COVER STORY: Food in the Nano Platter
Food security has always been the biggest concern of the mankind. Nations, communities and Governments have been struggling with the issue since long.
Particularly, it's a prime agenda for the developing world including India,
will nanotechnology be an answer to this problem?
SPECIAL STORY: A Boon to Alternative Energy
Nanotechnology allows manipulation and adjustment of properties of materials used in the renewable energy generation. When we go to the nano scale we get to
use an enormous increase in surface area in low volume for reactions and
movement of charged particles made feasible by the nano scale.
Development in biomedical apparatus highlighted
The last decade has seen rapid progress and development in the biomedical apparatus; specifically the diseases of the cardiovascular systems contribute
to about 20 per cent of the mortality in older people. Arteriosclerosis a
problem appearing in the large and medium sized diameter arties, specifically
the aorta, coronary arteries and cerebral arteries is a major cause of death.
JNTUH to hold Nano Conference
The Centre for Nanoscience and Nanotechnology of Jawaharlal Nehru Technology University of Hyderabad will host two day national conference on Introduction
to Nanoscience, Nanotechnology and Applications (INTA – 2010) from September 2,
SUCCESS STORY: Nanomaterials can be Prepared with Water
The requirements of simple and reliable protocols for the preparation of nanomaterials with controlled morphology continue to be a major challenge in nanoscience.
INDUSTRY WATCH: Indigenous Nanomaterials Manufacturer
Quantum Materials Corp, Bangalore based nanomaterials and other smart materials manufacturer is one of leading nanotech companies in country and
intends to “take nanotechnology from the lab to market-place”. With the
intention of commecialising he nanotech products and nanomaterials, the company
has recently start the manufacturing unit at Bangalore and is already
manufacturing carbon Nanotubes (CNTs), graphene, smart polymers, Zinc Oxide
Nanoparticles and Nanowires.
THEME: Food packaging materials with Biodegradable plastics
Presently whole world seems to be wrapped in plastic. Almost all product we buy including food, come encased in plastic. Packaging is the
largest market for plastics. In the past 20 years, the production and the use
of plastics in the world have enormously increased, worsening the problem of
the waste disposal. The growing interest in environmental impact of discarded
plastics has directed research on the development of plastics that degrade more
rapidly in the environment, leading to a complete mineralisation or bioassimilation
of the plastics.
New Dimension to Food Industry
A derivative of chemistry, engineering, and physics, and micro falsity techniques, nanotechnology involves manipulating matter at the
nano scale level. It is responsible for determining not only that biological
and non-biological structures measuring less than 100 nm exist but also that
they have one-of-a-kind and novel functional applications. In fact, the
National Nanotechnology Initiative (NNI, 2006) defines nanotechnology as “the
understanding and control of matter at dimensions of roughly 1 to 100
nanometers, where one-of-a-kind phenomena enable novel applications.”
FEATURE: Nanovaccines against Hepatatis B
Vaccines are medications designed to stimulate the body's immune system to generate a response that will protect the individual from
disease by the pathogen in question. Vaccines generally consist of pathogens in
weakened or killed form. Vaccines are used as a measure of prevention of a
particular disease as well as a measure to cure ailments.
Nano for Energy: Demand of the Days
The energy shortage in the world is among the biggest concerns in the present time. We can
not cater the demands of the people with enough energy in the coming decades
using only electric power. The
production and use of oil and other fossil fuels continues to rise on a yearly
basis to record new levels. At the same time, fewer new oil fields are being
identified which means that sometime over the few decades oil production will also
not be able to satisfy the demand.
Nanotechnology in Agriculture
Research in nanotechnology has extremely high potential to benefit society through applications in agriculture and food systems. Over 400
companies around the world today are active in nanotechnology research and
development (R&D) and this number is expected to increase to above 1000
within the next 10 years. In developed countries, the food industry is driven
by consumer demand which is currently for fresher and healthier foodstuffs.
This is big business! For example the food industry in the UK is booming
with an annual growth rate of 5.2 per cent and the demand for fresh food has
increased by 10 per cent in the last few years.
Mumbai’s N Shankaran Nair Research Center (nsnRc) for Nanotechnology and Nanobiotechnology is a new abode for nanotech research in India.
This centre which has come up recently promises to deliver some exciting and
path-breaking results in the near future is spearheaded by Prof Maheshwar
Sharon, retired professor from IIT Bombay and Professor Emeritus CSIR and UGC.
The centre has come up under the South Indian Children Education Society
(SICES) and was inaugurated in March this year by Dr Michael Neumann-Spallart
of CNRS, Meudon France “with whom Professor Sharon has been collaborating since
1985 in the area of Photoelectrochemistry.”
