The angiotensin‑converting enzyme (ACE) converts angiotensin‑I to angiotensin‑II – the protein known to induce hypertension. The gene that encodes ACE comes in two forms: one with a deletion (D) and another with an insertion (I) of 287 base pairs of gene sequence. The earlier studies had shown the linkage of hypertension with the D form of the gene.

In the present study, 46 healthy young men with normal blood pressure, who lived in plains, were taken to Ladakh (3500m), where they stayed for 30 days. During this period 18 of them developed hypertension. Their DNA analysis showed that those who developed hypertension had a significantly higher amount of ACE D than those who remained normal. Results of the present study suggest that environmental changes and pre‑existing genetic factors, viz. the ACE D allele, might be the two of the factors predisposing natives of low altitudes to systemic hypertension, a polygenic disease, at high altitude.

Sudden changes in desert water-level may help in earthquake prediction

SIGNIFICANT changes in water levels of shallow and deep borewells before and after earthquake events were observed in the Thar Desert of India and reported for the first time by D. Muralidharan, R. Andrada and U. Satayanarayana of the National Geophysical Research Institute, (NGRI) Hyderabad, in their presentation at Conference of the Society of Petroleum Geophysists held in Hyderabad, during 16-17 January 2004. Rise in water level of the deep well (165-m depth) was of the order of 5 to 50 cm and was observed prior to earthquake events having epicenters at distances ranging between 100-800 km. Analysis show the water level changes directly proportional to the magnitude-distance ratio (magnitude/epicentral distance) and inversely proportional to the epicentral distance. Sudden drop in water level of 1-2 m is a unique experience observed on 13 occasions during a four-month period of observation (Dec 2001-March 2002) at deep borewell. The fall in water levels was associated with global events in some cases and signifies the sensitivity of the site in arid conditions for earthquake precursory studies. The plot of epicenters is found to be falling in two major trends of N-S and NE-SW directions, which are transverse to the Himalayan arc and sub-parallel to the Aravalli Range respectively. These preliminary observations signify the favourable conditions of the desert environment to be a good sensor for earthquake hazard management of densely populated northern continent of India.


Correlation of changes in water level between December 2001 and March 2002 in the Dumki deep-bore well in the Thar Desert with earthquake occurring at various distances from the well. The changes in water level in the
 24 hours before a quake provide a means of earthquake prediction, but there is currently no
 information about where the quake will strike

Annual Day Celebrations


CDRI Forges Ahead


THE Central Drug Research Institute (CDRI), Lucknow, celebrated its 53 Annual Day on 17 February 2004. The occasion was graced by the presence of Dr R.A. Mashelkar, Director General, CSIR and Dr R. Kumar, Emeritus Professor, Indian Institute of Science, Bangalore, who presided over the function. The event was also accompanied with the inauguration of second International Conference on `Current Trends in Drug Discovery Research – 2004' (CTDDR‑04) by Dr Mashelkar. Prof. David J. Triggle of USA, delivered the key‑note address on `The shape of medicines to come: Pharmaceuticals in the 21st century'.

Earlier, in the forenoon, Prof. Goverdhan Mehta, Director, Indian Institute of Science, Bangalore, delivered the CDRI's coveted Sir Edward Mellanby Memorial Lecture on `Natural Products, Organic Synthesis and Drug Discovery: Triumvirate for Human Welfare'.

The Charitable Foundation Scientific Partnership, Moscow, in recognition of CDRI's contribution to world science and international scientific collaboration, awarded a Gold Medal to the institute for the year 2004.

The highlight of the Annual Day celebrations was the presentation of CDRI Annual Report by Dr C.M. Gupta, Director, CDRI. This was the seventh annual report presented by Dr Gupta as the institute's Director, and while highlighting the achievements of the past one year, he also recalled some of the significant milestones achieved during his overall tenure as the Director.

Dr Gupta said that the major agenda given to him at the time of his joining as the Director of the institute was to strengthen the institute's foundations by inducting young talents to improve the quality of manpower, and basic science, modernizing the infrastructure and expertise to bring the institute at par with international standards in drug discovery research, developing a strong pipeline of candidate drugs, licensing of the existing technologies, improving the quality and number of publications in SCI journals. He informed that the institute has progressed well and if the present level of progress was maintained for the next 4‑5 years, he was confident that the institute would become one of the best institutions in the area of new drug discovery research and development.

Describing the achievements, he pointed out that  CDRI had successfully licensed Bulaquin (anti‑relapse antimalarial drug) and Guglip (cholesterol lowering herbal preparations) to Nicholas Piramal Ltd, and the Compound 80/574 (Hypolipidaemic) to Cadila Pharma, the CT‑1 (herbal anti‑diabetic) to Nicholas Piramal Ltd, herbal cream Consap (strong spermicidal and select antimicrobicidal) to Hindustan Latex Ltd, Standardized Brahmi Extract (memory enhancer) to Lumen Marketing Company and among the formerly developed drugs Centbutindole (analeptic) and Centpropazine (antidepressant) to Merind. While Bulaquin with the trade name Aablaquine was released in 2000 and the standardized Brahmi Extract with the trade name Promind was released for marketing in 2002, the Consap was ready for release for limited marketing on that day.

The external cash flow (ECF) (excluding lab reserve) had continuously increased since 1998, and last year onwards it had crossed Rs 90 million mark. The position with regard to research publications had remarkably improved since 1998 when CDRI published only 90 papers in SCI journals with an average impact factor of about 1.7, but in the year 2003, 126 papers were published in SCI indexed journals with an average impact factor of about 2.1. The number of papers published in journals having an impact factor of more than two had steadily increased over the last 6 years. In 2003, this number was 63 as compared to 25 in 1998. Similarly, the number of patents filed abroad had also showed a steady increase. The total number of foreign patents filed during 1998‑2003 was close to 125, of which 39 patents had been granted. In addition, 79 patents had been filed in India.

Owing to restrictions on new manpower induction, little or no induction of fresh manpower could be made during 1988‑97. A large number of senior scientists superannuated during this period, but the positions could not be filled by fresh manpower. It was absolutely essential to induct young blood in large numbers at various levels to carry on the drug development programme at the desired pace. During the last 6 years, over 50 appointments were made and out of these 40 new scientists were in position and 5 more were expected to join.

New blood induction has enabled the institute initiate some new activities, virtually absent but required for upgrading the current approaches in new drug discovery. New blood induction helped strengthen several of core divisions such as Division of Medicinal Chemistry, Pharmacology, Microbiology, Pharmaceutics, Pharmacokinetics, Toxicology, Endocrinology, etc.

The institute also laid considerable emphasis on the recruitment process for research fellows. Also, an MoU was signed with the Jawaharlal Nehru University for recognizing CDRI for the purpose of the award of Ph.D. degree. These steps significantly improved the quality of Ph.D. students, evident from the fact that the number of CSIR‑UGC NET qualified Ph.D. students had increased from 10 in 1997 to exceeding 80 now. The net effect of the overall efforts made in this direction can be co‑related with the improvement in quality and number of CDRI publications and patents.

Dr Gupta said that CDRI has continuously focused on some select disease areas of high national relevance, i.e. Malaria, Tuberculosis, Diabetes and Associated disorders, and Osteoporosis. For all these disease areas CDRI has complete set of animal models and required expertise in biology and chemistry. Besides, traditional herbal therapeutics have been identified as an important activity of the institute.

He thanked CSIR and DST for their financial support for modernization, resulting in the establishment of full‑fledged faculties in combinatorial chemistry, high throughput screening, macromolecular x‑ray crystallography, DNA micro array, proteomics and several other state‑of the‑art facilities.

Regarding the CDRI's drugs in pipeline, Dr Gupta informed that the herbal hepatoprotective, Picroliv and anti‑diabetic CT‑1 had reached phase III and phase II trials, respectively. In addition, two synthetic compounds, namely 97/98 (anti‑malarial), 99/373 (anti‑osteoporotic) and four natural product preparations, namely, CDRI‑134 (anti‑diabetic), fish oil (hypolipidaemic), plant 109 K022 (anti‑stress) and a herbal medicament (anti‑cerebral stroke) had reached the stage of pre‑clinical toxicity studies. In addition, there were a number of promising leads in the areas of anti‑tubercular, anti‑leishmania, anti‑breast cancer and anti‑osteoporosis.

Highlighting the accomplishments of the past one year, Dr Gupta said that the ECF was expected to be more than Rs 90 million.

“We have not only licensed the contraceptive cream 'Consap' to the Hindustan Latex Ltd but also finalized licensing of herbal medicament for treatment of cerebral stroke to a company, with the CSIR approval”, he informed. The collaboration with Novo Nordisk had moved quite well during the past four years, leading to identification of a number of promising leads in diabetes and dyslipidaemia with the possibility of entering second phase of collaboration and for that the agreement had been extended by another six months. It was hoped that something worthwhile would emerge from the collaboration, Dr Gupta said.

Of the 140 research publications, 126 were published in SCI journals with an average impact factor of 2.1, and 19 Indian patents and 32 foreign patents had been filed. He reported satisfactory progress in phase III clinical trials of Picroliv (hepatoprotective), grant of DCGI's permission for clinical trials of CT‑1 (anti‑diabetic) and submission of dossiers on aArteether to DCGI for undertaking phase III clinical studies for its use in children and on CDR‑134 (anti‑diabetic) for undertaking phase I clinical trial. A number of `hits' in various disease areas including cancers had been identified through high throughput screening of the institute's chemical libraries. Some of those `hits' were being structurally diversified using combinatorial chemistry to identify leads under collaboration with an Indian pharma company. In all, about 15,000 samples have been tested during the year.

To strengthen CDRI's armamentarium of in vitro models, the institute has pursued a programme to acquire or develop as many in vitro models as possible leading to addition of some in vitro models for osteoporosis and tuberculosis. Similar efforts were on in the area of malaria and leishmania. Institute's chemical library has steadily grown to over 15,000 compounds. It is hoped that the target of 50,000 compounds would be achieved in the next 3‑4 years.

The institute staff received several honours and awards during the year. Dr Gupta was awarded Prof. B.N. Ghosh Memorial Oration of the Indian Pharmacological Society and R.K. Dutt Memorial Award of the Indian Science Congress. Dr Vinod Bhakuni was elected to the Fellowship of Indian Academy of Sciences, Dr Ashim Ghatak was awarded K.G. Nair Oration Award of Indian Society of Hypertension and the Hindi Officer, Dr V.N. Tewari was honoured with the prestigious Indira Gandhi Official Language Award. Further, Dr Pradip Srivastava and Shri R.P.S. Parti were awarded the Indian Science Writer's Association National Award and Best Poster Award, respectively. Dr K.R. Arya was elected to the Fellowship of Society of Ethno botanist.

Dr S.P.S. Khanuja, Director, CIMAP, welcomed the visitors and guests and mentioned about the major achievements of the institute during 2003‑04. Dr Khanuja stated that CIMAP is committed to make available the plant‑based technologies, products and molecules for green entrepreneurship to the rural entrepreneurs and pharma industry in a mission mode. After achieving the remarkable success in development and dissemination of menthol mint, CIMAP is now focussing its attention on dissemination of geranium and other plants through demonstrations, training and interactions. Dr Khanuja further said that process knowhow and product formulations developed by CIMAP are attracting the industries and entrepreneurs from across the country. Under the 'Mission Tarang' programme, Dr Khanuja informed, CIMAP would be setting up the herbal gardens in schools and adopt them as 'Gyanika'. On this day the three 'Gyanikas' adopted were Spring Dale Inter College, Indira Nagar and Kanpur Branch, Maharishi Vidya Mandir, Sitapur Road. This would facilitate CIMAP in providing scientific basis and education to the students about utilization and conservation of medicinal and aromatic plants.

Delivering his special lecture, Dr Nitya Anand dwelt upon the technological and industrial development that have taken place in the country, which are paving the way for the further realization of targets in various sectors. Now India has reached the stage where Indian pharma company are able to manufacture the drugs needed from basic stage, at prices which could be lowest in the world. India has become an important generic resource for production of cost‑effective generic drugs. There has been a virtual Pharma Revolution, he added. Elaborating his view point on the unified picture of the universe, Dr Nitya Anand said that there are two facets of our scientific life with medicinal and aromatic plants, one is the opportunity to provide medical, agricultural and industrial benefits to the society and the second facet is the opportunity it provides us to understand our place and position in the universe, our 'communion' with all that exists; the former gives us the passion for work and is the opportunities of understanding life in full and to live with 'compassion'. Living with passion and compassion gives much meaning to our life, Dr Nitya Anand emphasised. On this occasion he also released CIMAP newsletter both in print form and in CD and also planted a chandan sapling in the campus. The winners of the previously organised competitions were awarded on this occasion.

Workshop on Organic Synthesis Directed Towards Chemical Biology & Chemical Genetics

ORGANIC chemistry has been undergoing a lot of changes for the last decade or so.  More and more research groups are using new small molecules available in organic chemistry realms and applying them to perturb a biological system in order to understand various complicated biosynthetic pathways.  It is felt that the concept popularly known as Chemical Genetics is going to have a lot of impact in the years to come.  It has been recognized that India has got a great pool of knowledge in the art of practicing Organic and Natural Product Chemistry.  However, collaborative efforts at the interface of chemistry and biology by industry and academia are not intense so far in India.  In order to inculcate active collaborative efforts in this growing field, a two‑day workshop was organized on 2‑3 February 2004 at the National Chemical Laboratory (NCL), Pune. The eminent people working in combinatorial chemistry delivered a series of lectures covering variety of topics like Combinatorial Chemistry, Chemical Genetics, Diversity Oriented Synthesis of Combinatorial Libraries, Catalytic Antibodies, Nucleic Acids and Nucleotide Chemistry.

Dr K.N. Ganesh, Convener (extreme right) seen along with the distinguished speakers at the
 Workshop on Organic Synthesis Directed Towards Chemical Biology & Chemical Genetics

 More than fifty delegates from major pharmaceutical companies and academic institutions attended the workshop.  Dr S. Sivaram, Director, NCL, in his address emphasized that organic chemistry alone would not be sufficient to discover new bio‑active molecules and suggested that collaborative efforts would give more success than individual endeavours.  Dr K.N. Ganesh, Convener of the workshop and Head, Organic Chemistry Division, in his keynote lecture introduced the state‑of‑the‑art facilities established in the Combi Chem ‑ Bio Resource Center at NCL.

On the first day of the workshop, Prof. Prabhat Arya, National Research Council, Canada, delivered two lectures and introduced the modern methods in combinatorial chemistry and natural products chemistry.  Prof. Michael Blackburn, University of Sheffield, UK, spoke on how catalytic antibodies would be useful in catalyzing various biochemical reactions. Prof. Larry McLaughlin, Boston College, USA, in his lecture highlighted how nucleic acid chemistry can impact novel drug discovery. Dr Srinivas Hotha, Scientist, NCL, while speaking on diversity oriented synthesis (DOS), explained basics of DOS‑based drug discovery.

Prof. Prabhat Arya delivered two more lectures on the second day of the workshop covering the paradigm shift of organic chemistry to the field of combinatorial chemistry and stressing the role of natural products and natural product‑like molecules in the post genomic era.  Prof. Michael Blackburn highlighted their group efforts in understanding a variety of problems in biology using small molecule probes. Dr Yogesh Sanghvi, Rasayan Inc., USA, discussed at length the development of novel protecting groups for nucleosides.  Dr Srinivas Hotha delivered a lecture on the discovery of HR22C16, an Eg5 inhibitor, by chemical genetic screening.  Dr Sami Mukhopadhay of VLife Sciences Technologies gave a demonstration of their Molecular Drug Discovery Suite package.  Later, all the participants of the workshop visited the newly established state‑of‑the art facilities available at the Combi Chem – Bio Resource Center of the NCL.  Overall, this workshop has enlightened the participants on the role that organic chemists are going to play in the post‑genomic era.



Workshop on `Safety Aspects of Chemicals and Biological Hazards


A one‑day workshop on `Safety Aspects of Chemicals and Biological Hazards', was organized at the Industrial Toxicology Research Centre (ITRC), Lucknow, on 10 February 2004, for scientific and technical staff as well as research students to apprise them with safety precautions while working in the laboratory and to manage the maintenance of laboratory chemicals, disposal of wastes and washing etc. in a safe manner. The workshop began with the inaugural lecture by Prof. (Smt.) Sita Naik SGPGI, Lucknow, on `Safety aspects for handling of biological sample with reference to human'. Presiding over the workshop, Dr R.C. Srimal, former Director, ITRC, stressed the need for orientation of young scientists towards safe use of modern tools with judicious applications of safety measures to avoid the element of risk while working in laboratory. He expressed that such workshops are very useful for everybody involved in laboratory working and management.

Dr (Smt.) Ranjana Srivastava, Scientist, CDRI, Lucknow, in her lecture on `Safety guidelines for working with infectious organisms', highlighted the basic requirements for any laboratory using infectious toxic agents and their biosafety levels defining those condition under which such agents can be safely handled. She also illustrated various classes of biological agents based on their risk factors.

Prof. U.C. Chaturvedi, Emeritus Professor, ITRC, in his lecture outlined `The principle of microbiological safety and how to identify the associated risk. Explaining different categories of microbes and protective measures to be followed, he outlined how the microbial waste could be organized before its disposal.

The afternoon session was assigned for chemical safety measures, and it started with a lecture by Dr D.K. Agarwal, Scientist, ITRC, on `Reactive and toxic chemical hazards'. He described the chemical decomposition and classification of reactive chemicals, elaborating on the physical and chemical properties of compounds leading to potential health hazards. He stressed that the biological system response to a chemical must also be defined by species, sex, age and individual variations, and pointed out that  information on the dose or exposure is the prerequisite for the evaluating toxic hazards. He discussed the consequences of acute chronic exposure to such chemicals on different body systems. A knowledge regarding incompatible chemicals is necessary to avoid danger in storage of such combinations together. Proper disposal of chemical waste after neutralization, dilution and adsorption in a landfill while keeping the records of the quantities was also pointed out.

Delivering his lecture on `Laboratory chemical spills and hazardous waste management', by Dr J.R. Behari, Scientist, ITRC, and convener of the workshop, he explained how minimum exposure to chemical could ensure safety and avoid risk and how the liquid and solid chemicals spill in the laboratory could be managed. The clean up procedure was illustrated with example of inorganic mercury spill. Handling of acids, specially perchloric acid, with proper precaution was illustrated. Hazardous characteristics of chemical substances were explained and the role of personal behaviour in ensuring laboratory safety discussed. An overview of laboratory safety consideration was presented by Dr R.K. Upreti, Scientist, ITRC. Besides general lab safety measures, Dr Upreti also discussed the change in the physico chemical properties with alteration in molecular structure leading to health hazards. Some chemical hazards owing to strong acids, alkalies, organic substances, mercury and microorganisms were discussed and the first‑aid measures outlined.

In the concluding session, Er. K.K. Gupta, the then Officiating Director, ITRC, emphasized the significance of such workshops.



Workshop on Modelling of Creep in Engineering Alloys


A 2‑day workshop on modelling of creep in engineering alloys was held at the National Aerospace Laboratories (NAL), Bangalore, in the recent past. This formed a part of the international collaboration National Metallurgical Laboratory (NML), Jameshedpur, had with the Department of Materials, Imperial College, London over a period of three years. The Engineering and Physical Sciences' Research Council of UK supported this interaction.

The progress in modelling the creep behaviour of power generation and aerospace materials that has been achieved at Imperial College, London, NML, and elsewhere was presented at the workshop. The main focus has been on how to explicitly incorporate knowledge of the microstructural evolution and the deformation mechanisms using the formalism of Continuum Damage Mechanics. It is believed that with the availability of increased power of computing microstructure explicit modelling will replace the current life prediction methods for high temperature components, which is based on empiricism and requires costly long‑term experiments to be carried out.

Prof. Malcolm McLean, Department of Materials, Imperial College, introduced the topic and described the limitation of current method of creep life prediction of engineering materials. He also explained the evolution of continuum damage mechanics and its potential in describing structural changes taking place in engineering alloys during high temperature service. The illustrations clearly revealed that although the nature of the creep strain time plots of various materials may look similar the underlying mechanisms might be entirely different. He further explained how by conducting diagnostic tests one could identify this.

Prof. David Hayhurst of Department of Aerospace & Manufacturing Engineering, University of Manchester, explained how the information collected from uniaxial tests could be used in the design of components having a multi‑axial stress field. The stresses get redistributed owing to creep. The presence of a variable temperature field could make this even more complex. With the growing computational power it is possible to use continuum mechanics based formulation to map not only the evolving stress field but also plot damages accumulating at various places. Case studies depicting use of this method to map the performance of a welded joint were presented.

Prof. Brian Dyson of the Department of Materials, Imperial College, explained how our current knowledge of material behaviour, evolution of microstructure, phase transformation and environmental interaction could be used to develop the basic formalism of a model based approach for creep life prediction. The main advantage of this approach is that many of the parameters describing the creep behaviour can be calculated from our basic understanding of the underlying physical processes.

Dr Hector Basoalto displayed the main features of user‑friendly computer software developed by him incorporating the formalisms developed by Dyson and McLean. A number of case studies on nickel and aluminium based alloys were presented. It was shown that how by incorporating an additional mechanism depicting cavitation it was possible to explain the creep behaviour of conventionally cast nickel based superalloy using the material database for a directionally solidified alloy.

Dr R.N. Ghosh of NML explained that how by incorporating the concept of crystallographic slip in the model it is possible to explain creep anisotropy exhibited by single crystal superalloy. He also presented a case study illustrating how our current knowledge on the mechanisms of creep deformation and environmental attack could help in estimating lives of ageing high temperature components made of ferritic steel.

Dr Sanjay Sondhi of NML, showed evidence of negative creep in nickel based alloys used as turbine disc having bimodal distribution of particles. He further explained how modelling coupled with planned experiments could help establish the cause. Disc alloys are made through powder metallurgical route. A compressive stress field surrounding the precipitates is responsible for the phenomenon under tensile loading.

The workshop had about 40 delegates from various organizations like Indian Institute of Science, Bangalore; National Institute of Technology; Surathkal; Indira Gandhi Centre for Atomic Research, Kalpakkam; Defence Metallurgical Research Laboratory, Hyderabad; Gas Turbine Research Establishment, Bangalore; Hindustan Aeronautics Limited; GE Bangalore; CEMILAC; ALSTOM Power, Vadodara; Central Power Research Institute, Bangalore; NAL and NML.  The delegates actively participated in the lively discussion all through the proceedings.

Dr B.R. Pai, Director, NAL, inaugurated the workshop. Dr R.V. Krishnan of NAL welcomed the delegates. Prof. M. McLean apprised the participants about the workshop. Dr R.N.Ghosh acknowledged the generous support provided by EPSRC, UK; Department of Materials, Imperial College, London; NAL; NML; and a host of other organizations who sponsored the delegates in organizing this event.

Training Programme on Work Culture, Managerial Excellence and Decision Making


A one‑day training programme on `Work Culture, Managerial Excellence and Decision Making in the context of Globalization' was held at the Indian Institute of Petroleum (IIP), Dehra Dun, on 19 February 2004 for its senior and middle‑level scientists and officers from administration. The programme was conducted by Shri S.K. Sabherwal, a senior management consultant and was attended by 30 participants.

During the past 15 years, India has witnessed an era of monumental economic reforms. The emphasis has shifted from control to incentive, regulation to promotion, and autarky to globalization. This has generated tremendous competitive pressure in the economic environment. It has become necessary to improve the skills to cope up with challenge posed by globalization.

The training programme highlighted the additional core managerial competencies required for achieving further performance enhancement and better professional work commitment, and the unique and critical Globalised Managerial Skills – qualitatively and dimensionally different from run‑of‑the milk skills – which drive other world class institutions for achievement of globalized standards of Performance Efficiency, the key `mantra' for survival in this era of fierce world wide competition.

Maintaining that the best world class institutions don't do different things, but do things differently, Shri Sabherwal advocated four powerful strategies to meet and beat the competition headlong:



Short‑term Course on Earthquake‑resistant Design & Construction

EARTHQUAKE Engineering has assumed much greater significance since the deadly earthquake that struck Bhuj on 26 January 2001. The visible issues requiring a review of the current approach included ignorance of earthquake‑resistant design, continuation of age‑old traditional construction practices and disregard to the coal provisions. With a view to generating awareness regarding earthquake preparedness and mitigation among the middle and senior level engineers of Delhi Development Authority (DDA) and Municipal Corporation of Delhi (MCD), the Central Building Research Institute (CBRI), Roorkee, organized a training course on `Earthquake‑resistant Design & Construction' during March 2004. Twenty‑five participants from DDA and MCD participated in the course, which comprised eight technical sessions covering a wide spectrum of earthquake engineering. The aspects covered include seismicity, lessons from earlier earthquakes, design philosophies and principals, codal provisions, seismic evaluation and retrofitting and soil liquifaction. An interactive session was also held which specially addressed pragmatic problems faced by the engineers.

Prof. Prem Vrat, Director, IIT‑Roorkee, inaugurated the course and Shri V.K. Mathur, Director, CBRI, presided over. Speaking on the occasion Prof. Prem Vrat stressed the need to synergize the theoretical concepts in earthquake engineering with practice and organization of such courses will help in this task.

Prof. Holderich delivers Dow Endowment Lecture at NCL


PROF. Wolfgang F. Holderich, Director, Chemical Technology and Heterogeneous Catalysis, University of Technology, RWTH Aachen, Germany, delivered the first Dow Endowment lecture on 11 March 2004 in honour of Dr Paul Ratnasamy at National Chemical Laboratory, Pune. Dr Ratnasamy, who was Director of NCL from 1996 to 2002, made substantial contributions to both fundamental and applied research in catalysis. His research has resulted in the publication of 160 papers in international journals and about 125 patent applications. He established the Catalysis Division at NCL in 1980 and was its Head until he took over as the Director in 1996. Prof Holderich spoke on `New Heterogeneously Catalyzed Processes for Environmentally Benign and Sustainable Chemical Production'.

University of Technology, RWTH Aachen, Germany, delivering the first Dow Endowment lecture at NCL

In his lecture, Prof Holderich gave glimpses of the current chemical research in `Green chemistry'. He said, “In the past, we always thought that environmental protection was an expense. But environmental concerns and regulations have increased in the public, political and economic world over the last fifteen years because the quality of life is strongly connected to a clean environment.” Sustainable use of renewable natural resources was included in the agenda 21 of the Rio de Janeiro concept for the 21st Century.

He gave measures for sustainable development, economically benign and sustainable production and strategies for environment protection. For sustainable development, he said, “The chemical industry is targeting the sustainable improvement in the areas of environment, health and safety. Economic consideration should not be favoured over safety, health and environment.  The end product should be recyclable and easily disposable”. Presenting the criteria for economically benign and sustainable production, he said, “It is desirable to convert 100% of the raw materials into 100% of the desired product, no waste or by‑product formation, only one‑product, no emission and reducing reaction steps”. While elaborating on strategies for environment protection, he recommended that the waste produced in the chemical processes have to be destroyed in a consecutive procedure, in a separate unit and the formation of waste and by‑products should be avoided during the production of the desired compound by the application of catalysts.

The development of more efficient and selective catalysts and the realization of new and sustainable process technology are strongly related to environmental compatibility. This can be achieved in two ways:— One is the “end‑of pipe” technology in which processes are adapted to the more severe emission control regulations via consecutive costly separation procedures and catalytic transformations, such as in exhaust gas car converters. The second approach is the production or reactor integrated environment protection. In this approach, the formation of pollutants is minimized or even completely avoided by the development of alternative technology in chemical transformations. The interest of the chemical industry is in sustainable and green developments in which catalysts act as modern tools to carry out reactions that are very selective to the desired products. The catalyzed reactions, typically employed in the petrochemical and chemical industries, also enable the production of the desired products through utilization of the resources without the formation of by‑products and waste.

He gave examples of a few novel catalytic processes that are environmentally safer than the earlier processes. The new tert‑butylamine production via direct amination of isobutene over solid catalyst is an environment friendly and sustainable process in which the number of steps are reduced, no hazardous chemicals are produced and the amount of starting material per tonne of tertiary‑butylamine is reduced by 80% as compared to the conventional process. e Caprolactam, one of the top fifty chemicals, is an important precursor for nylon‑6 and plastics and development of a new sustainable production route to caprolactam is urgently necessary, since about 4.5 million tonnes of it are consumed every year. He said a new caprolactam process via Beckmann‑rearrangement over a zeolite catalyst has 97 to 98% selectivity and has been commercialized recently in Japan. He also cited the examples of new routes for aziridine production by direct dehydration of ethanolamine and for citral production using solid catalysts.

Due to economic and ecological reasons, renewable feedstocks are finding increasing interest in recent years.  These feedstocks can be based on the over‑capacities of our agricultural economy and save crude oil and gas resources.  At present in USA and in some parts of the Europe, renewable raw materials contribute ten per cent to the feedstock consumption of the chemical industry and it is estimated that 25% of organic chemicals will originate from renewable feed stocks by the year 2020.  He also listed a few of the chemicals being manufactured from renewable feedstocks including p‑cymene. Though a few chemicals have been commercialized so far, in most cases the products obtained from renewable raw materials are not competitive with the products of petrochemistry at present because of the low cost of crude oil. He urged chemists, biotechnologists and agriculturists to work together to develop oils and fats as renewable feedstocks for the chemical industry. “In the near future, we may see super absorbent diapers made from starch and cellulose,” he added.

Earlier, Dr S. Sivaram, Director, NCL and Chairman, NCL Research Foundation in his welcome remarks briefly outlined Dr Ratnasamy's seminal contribution to the chemistry of catalysis.
