Catalysis
- NCL has developed
world class technologies in the areas of petroleum refining, petrochemicals
refining, and fine chemicals.Notable success are catalysts and processes
for isomerisation of xylenes, ethylbenzene, C6/C9
trans-alkylation, maleic anhydride, ethyl methyl ketone, acetic
acid, benzofuran, guaiacol, m-hydroxyanisole and propionic acid The accent
is on ecofriendly greeen processes, in which the use of hazardous chemicals
is eliminated. A process is jointly developed with Reliance Industries
Ltd. for linear alkyl benzene (LAB) that uses zeolites catalysts instead
of the highly corrsive and toxic hydrogen fluaride is a recent example.The
area of catalysis at NCL has the unique record of being the only one form
which a hi-tech product ( a state-of -the-art catalyst) has been exported
to an advanced wertern country.
Polymers
- In the area
of polymers, the laboratory has developed a fibre-reinforced thermoplastic
material and successfully used it for producing some critical components
of two wheeler engines. NCL and CBRI have jointly developed Beck-Bond,
a polyurethane waterproofing compound based on an eco friendly raw material.
NCL's Jalshakthi, a superabsorbing material with uses in agriculture,
horticulture, and aforestation is already well known. Functionally-grafted
cable compounds, meeting the stringent specification of the cable industry,
have been developed in collaboration with Cable Corporation of India Ltd.
Membrane filters for Oxygen enriched air, membrane filters for drinking
water, controlled release formulation of drugs, vaccines and pesticides,
and composite bearing bush are among the other products that are at various
stages of development.
- Frontier-area
research in the field of polymers being carried out at NCL includes the
design of novel membrane materials for gas seperation through mollecular
modelling; polymers with controlled mollecular properties for use as viscosity
index omprovers; novel self-associating polymers for drag reduction in
oil pipelines; inteligent materials such as smart gels for application
is seperation technology, enzyme mimics, etc.; manipulation of polymer
surfaces/intersurfaces for improving their barrier/adhesive properties,
and water-borne adhesives and surface coatings eith enhanced ecofriendliness.
Organic
Chemical Technology
- NCL has strong
linkages with chemical industry and is uniquely equipped to tacle current
and futuristic problems of the industry. One of the recent successes include
novel oligonucleotide probes for replacing hazardous radioactive probes.
- Some other success
in this area include complex synthesis of brassionolide, biotin, prostaglandins,
and vitamin B6 . A unique synthesis of the ranitidine intermediate,
methylamino methylthionitroethane with a zeolite catalyst, and that of
a key intermediate of carbomate pesticides illustrate NCL's commitment
to clean technology. An example of interdisciplinary research is the microdial
transformation-based synthesis of phenylglycine.
- Probing nature
for obtaining useful molecules also finds an important niche in NCL's programme.
This has lead to the isolation of two anti-cancer agents, vinblastine
and vincristine from the plant Catharantus roseus, two biopesticides
from the Indian neem, and a process for morphine and codeine
starting from opium.There is also considerable stress for synthesis
for new molecules with commercial potential like anti-cancer and anti-HIV
agents, cardiac and anti-malarial drugs, plant growth promoters and dye-intermediates.NCL's
early concern about heavy loss of agricultural products cuased by insect
pests resulted in the development of processes for endusulfan, dimethoate
and ethion, three pesticedes thar are still widely used.
Biotechnology
- NCL's strength
in biotechnology lie in enzyme engineering, fermentation technology, plant
molecular biology and plant tissue culture. An actinomycete strain Chainla
capable of improving the quality of dissolving pulp by removing xylans
from it; and alkalophilic Bacillus with a similar property; a high activity
alkaline protease secreting a strain of Conidiobolous; a high activity
Myrothecium verrucaria capable of producing chitinase; and the identification
chitin-degrading enzymes mark NCL's success in enzyme engineering.The continuous
fermentation technology (Encillium) for producing alcohol from molasses
using an immobalized yeast has been NCL's chief acheivement in the recent
years in the area of fermentation technology.In the area of plant molecular
biology RFLP and genetic engineering are being applied for breeding protein
enriched varities of rice and tur dal.
- A very significant
acheivement in the area of plant tissue culture in the development of a
fast growing variety of bamboo, in which the flowering time is reduced
from a few years to only a few weeks. Its other successes include a development
of a disease resistant and high yielding variety of sugarcane, and elite
varieties of forrestry trees like eculaiptus and salvadora; an isolation
of superior variants like Cardamom, turmeric and ginger. NCL's Superior
cardamom variety commercialised by A.V. Thomas & Co., has helped boost
India's export of this spice.
- Currently the
focus in on recovery of natural products from marine organisms; enhancement
of oil recovery using aerobic and anearobic microbes; isolation of oil
degrading yeast, bacteria and fungi; use of enzyme inhibitors as drugs,
a use of microbial products against plant pathogens. The National Collection
of Industrial Micro-organisms at NCL is a unique facility that reflects
India's rich biodiversity.
Basic Research
- NCL's policy
is that globally competitive technologies can be built only on a strong
science base.
- Important basic
research has been carried out at NCL that has potential applications in
materials, organic reactions, plant tissue culture and polymers. The discovery
that films of amphiphiles can be obtained through self organization without
the agency of a condensed solid-phase Langmuir monolayer has opened new
possibilities in material synthesis. NCL's exploration of nano particle
science has provided pointers to potential electro-chemical applications
including electrocatalysis, energy conversion and storage. Studies of Langmuir-Blodgett
films have not only thrown new light on the basic mechanisms but has laid
to deposition of TiO2 nanoparticles which can be employed in the harvest
of solar energy. The breakthrough in bamboo research, already described
also belongs to this category.
- NCL's current
research interests in basic science include photoinduced electron transfer
reactions, orgranometallic compounds in asymmetric synthesis, synthesis
of fluorescent probes, living anionic polymerisations, coupled cluster
methods in quantam chemistry, and non-linear dynamics of chemical reactions,
etc.
- NCL's innovation
in inducing enzyme-like activity in polymeric gels responsive to stimuli
(Gelzymes), and it's expolration of zeolites with enzyme like activity
(Zeozymes) are but two examples of NCL's diverse strengths interacting
with each other to produce novel results.
