The New Generation Eco-friendly Potent Plant Protection Agents
Abstract:
The importance of controlling pests has led to the
development of a variety of insecticides that prevent agriculture losses
and spread of diseases. Intensified research is leading to
chemically-modified substances with improved insecti-cidal activity in
terms of selectivity towards insects and low toxicity to the
environment.
The article gives a good comprehensive overview of the new
gener-ation plant protection chemicals. Latest non-chemical alternatives
are also described.
About the author:
Dr. Prem Dureja (PhD in Organic Chemistry and post
doctorate from University of California) Head, Division of Agricultural
Chemicals, IARI, New Delhi, has made significant contribution in
understanding environment chemodynamics of pesticides. Her research work
involves broad areas ranging from nature-based insecticides and
pesticides to new and efficient processes for existing pesticides, new
analytical techniques and synthesis of biodegradable organophosphorus
compounds. She has been honoured with several prestigious awards
notably, Rafi Ahmed Kidwai Award, Best Woman Agriculture Scientist award
(ICAR) and several awards for her excellency in teaching. She is Fellow
of National Academy of Agricultural Sciences and Society of Pesticide
Science, India.
Standards for Energy Efficient Motors and Calculation of Efficiency
Abstract:
For cost efficient operations, energy efficiency is paramount. Motors
are ubiquitous and are energy intensive. Therefore energy efficient
motors are today a fundamental necessity. The calculations involved in
energy saving, energy cost saving and pay back period are known to all.
The grey area is the ‘efficiency figures’. There are a few standards
with their own mathematics for efficiency calculation and allowable
tolerances on the efficiency figures. It may so happen, that a motor not
qualifying to be an EEM as per one standard, may fulfill all criteria to
be an EEM according to another standard.
The article gives an overview of EEM standards and the procedure for
calculating efficiency.

Machine & Drives) is a consultant in the field of design, application,
selection & energy audit of electric motors since last 10 years. Earlier
he was with Crompton Greaves Ltd for 20 years.
Rediscover
National Chemical Laboratory
Is there more to National Chemical Laboratory than
what is already known ?
There is a lot of exciting research going on at NCL, on many new areas
of
significant importance to Indian industry and Indian society, many of it
at the intersection of disciplines of frontier sciences. As NCL
celebrates its diamond jubilee year (2009-10), Chemical Industry Digest
visited NCL and interacted with the young breed of scientists who are
leading research efforts in diverse areas and discovered some of the
amazing work going on.
In the March’09 issue of Chemical Industry Digest,
the first part of the fascinating saga of research at NCL was covered,
where we presented a brief overview on the range of research activities
and detailed accounts of specific research going on like how unusual
media like water accelerate reactions and increase productivitites; on
the tremendous potential of microreactors, on solid state and structural
chemistry and on complex fluids which lie at the interaction between a
fluid and a solid like material.
Now read the second and concluding part of this first hand account.
Water and
Wastewater Management for Process Industries
Abstract:
Water is one of the most extensively used input in the process
industry (PI), whether it is in boilers for steam generation, reactors,
cooling towers or washing of equipment etc. Therefore, its conservation
and reuse are vital for the commercial success of any PI. Due to
increasing shortage in availability of ground water and surface water
resources, the strategies employed for water management and wastewater
treatment assume great significance.
This article provides a review of water use in process plants as well
as different ways of minimizing water consumption. The major focus is on
technology leads that could assist in controlling the quality of feed
water as well as treat effluents effectively for economical generation
of recyclable water.

5 th
BASF Boron Conference
New advances in organometallic
reagents for
commercial scale API synthesis
Recent developments in the use of borane reagents for
commercial scale API synthesis were highlighted at a March meeting of
over 150 scientists in Hyderabad, India.
The 5th
BASF Boron Conference featured presentations from leading academic and
pharmaceutical researchers from the global chemical community under the
banner "From Lab to Launch – Discover New Horizons." As such the focus
was on new innovations in organometallic cross-coupling reactions, and
the practical application of boron and organozinc reagents for the
commercial scale synthesis of complex molecules.
Some highlights from this conference are summarized here.
