    nano composites are likely to see a wide variety of defense related application once it can be made in industrial scale .The biggest advantage of these type of materail is it can be tailored to meet a specific need from aerospace components to flak jackets of a soldier to gun barrels -the range is limitless .
    more specifically it will make the aircraft fly faster with same engine power or make a submarine sink deeper without going for a very heavy pressure hull thereby making it more easily defensible in an underwater combat

    India develops affordable nano sensors to detect heart attack


    2010-01-06 16:10:00

    A team of Indian scientists and engineers has developed affordable sensors using nano materials to detect a heart attack quickly.
    'The device with nano sensors can not only detect a heart attack, but also transmit its signal through a wireless interface to doctors located remotely for quick diagnosis and treatment,' Indian Institute of Technology (IIT-Mumbai) professor V. Ramgopal Rao said Wednesday.

    Rao told delegates at the 97th Indian Science Congress here that the prototype would soon be introduced as a portable device in the market to help thousands of people prone to sudden cardiac disease wear it and carry on with their lives.

    'The three-dimension sensors use nano electrical mechanical system (NEMS) of its polymer material to convert any abnormal movement in the heart muscles into an electrical signal for detecting a cardiac symptom,' Rao said at a plenary session on 'Nano Technology and Education' at the country's premier science event.

    The team has built a cantilever in the sensor using tiny or nano-particles of the polymer to measure the stress symptom (myocardial infarction) in the heart and convert it into an electrical signal.

    Nano-particles, measured as one billionth of a metre (39 inches), in a polymer generate electrical current through biochemical process of the enzymes produced in the heart.

    The department of electrical engineering at IIT Mumbai took up the project in 2007, with funding from multiple agencies to develop affordable sensors for early detection of heart disease.

    'When the heart goes through severe stress or strain, it suddenly releases enzymes (protein molecules) in excess, causing pressure on its blood vessels and exertion, which manifest as chest pain, perspiration or even a cardiac arrest.

    Heart attacks, a cardiac disease, are on the rise in India owing to improper food habits and sedentary lifestyle of the people, especially in urban areas and hazardous occupations causing stress and strain.

    According to a recent study by Medwin Heart Foundation, a health organisation based in Hyderabad, about 60 percent of heart diseases worldwide are likely to occur in India by this year-end.

    'With so many Indians prone to heart diseases irrespective of age and gender, the portable device will enable cardiac diagnosis affordable and quick as against multiple and expensive tests carried out presently using conventional methods,' Rao noted.

    The study also revealed that half of all heart attacks across the country occur to people below 50 years and 25 percent under the age of 40 due to unhealthy diet, smoking, chewing tobacco, physical inactivity and changing lifestyle of the growing urban populace.

    The Telegraph - Calcutta (Kolkata) | Jharkhand | ISM scientist creates ‘cyclone’

    Dhanbad, Jan. 14:An ISM scientist has developed a “cyclone” that can disintegrate even the finest impure particles clinging to raw coal.

    Nikkam Suresh, the head of the fuel and mineral engineering department, has designed a “dense medium cyclone”, an equipment for use in coal washeries, after two years of rigorous research with engineers of Weir Minerals, the world leader in design and manufacture of processing equipment.

    Recipient of a number of awards, including the national mineral award from the Union ministry of coal in 2002 and the distinguished teacher award 2000, Suresh is now filing for a patent right along with Weir Minerals.

    The new equipment is an improved version of existing cyclones that are made of hard materials. The new version has 28 times more resistibility than the older cyclone and boasts of a longer life span.

    The equipment is expected to limit, if not end, India’s dependence on foreign suppliers. The device will also come in handy for the steel industry as it would help cleansing coal of impurities.

    Suresh, who has also won the Arti Bhatnagar award in 1996 instituted by Mining Geological and Metallurgical Institute of India, Calcutta, said: “The equipment can wash impurities as fine as 3mm or below”.

    Recently conferred the coal benefaction award at an international conference in Jamshedpur, Suresh lamented that more and more open cast mines were leading to bulk production, but the quality of coal had suffered.

    “I hope my equipment will help procure high quality coal and benefit allied industries and the country as a whole,” he added.

    Team BEL hands over the first prototype module to Dr Anna, Scientist, CERN, Geneva

    Bharat Electronics Ltd (BEL) contributed to the Big Bang experiment carried out by the European Organisation for Nuclear Research (CERN) recently. One of India’s leading Defense Public Sector Undertakings (DPSU), BEL supplied 32-channel silicon strip sensors to the Large Hadron Collider to detect subatomic particles generated after high-energy particle beams collided. “The BEL-made detectors were placed near the point of collision so as to capture the properties of these particles, thus giving an insight into the aftermath of the Big Bang explosion,” I.V. Sarma, BEL’s director of research & development, told Aviation Week.

    India to be part of 'robotic network' on red planet

    India has signed a statement of intent with space-faring nations including the US to work on the concept of establishing a "robotic network" on the surface of the Moon to conduct detailed scientific investigations.

    Replying to a question in Rajya Sabha, Minister of State for Science and Technology Prithviraj Chavan said the network called 'International Lunar Network' will carry out detailed scientific investigations on the Moon.

    "This is an international cooperative effort and will not constitute any binding commitments on the participating nations," he said.

    New vistas for Indian researchers

    Ananya Dutta
    KOLKATA: A dedicated beam line for Indian researchers at the Photon factory, a synchrotron, at the High Energy Accelerator Research Organisation (KEK) in Japan has become operational, according to authorities of the Saha Institute of Nuclear Physics (SINP), the nodal institute for the project.

    They told The Hindu here that the facility is available to Indian researchers as a result of an agreement signed between the Prime Ministers of the two countries in 2007 and the project is being conducted under the auspices of the Central Department of Science & Technology.

    Full capacity next year

    “The facility has been set up this month and scientists from several institutes across the country are currently in Japan to conduct their experiments. It will function at full capacity a year from now,” said Prof Milan K. Sanyal, Director of SINP.

    Currently researchers can apply for beam time at the Raja Ramanna Centre for Advanced Technology in Indore but the access to the synchrotron at KEK will increase the number of students who can avail of the facility, he added.

    As a budding inventor and scientist, Shree Bose, in second grade, tried to make blue spinach. In fourth grade she built a remote-controlled garbage can. In eighth grade she invented a railroad tie made out of recycled plastic and granite dust, an achievement that got her to the top 30 in a national science competition for middle school students.

    In 11th grade Ms. Bose, a 17-year-old in Fort Worth, tackled ovarian cancer, and that research won her the grand prize and $50,000 in the Google Science Fair last week.

    For the winning research Ms. Bose looked at a chemotherapy drug, cisplatin, that is commonly taken by women with ovarian cancer. The problem is that the cancer cells tend to grow resistant to cisplatin over time, and Ms. Bose set out to find a way to counteract that.

    She found the answer in a cellular energy protein known as AMPK, or adenosine monophosphate-activated protein kinase. She observed that when AMPK was paired with cisplatin at the beginning of treatment the combination diminished the effectiveness of cisplatin. But added later on, when the cancer cells were growing resistant, the AMPK worked to maintain the effectiveness of cisplatin, allowing it to continue killing the malignant cells, at least in cell cultures.

    “That opens up a lot of new avenues for research,” Ms. Bose said. Her research was supervised by Dr. Alakananda Basu at the University of North Texas Health Science Center in Fort Worth.

    More than 10,000 students from 91 countries entered the science fair, which was Google’s first. The entries, submitted over the Web, were winnowed down to 60 semifinalists and then 15 finalists who presented their findings to judges at Google’s Silicon Valley headquarters last week.

    Ms. Bose’s research was named best in the age 17-18 category and best of show over all. Her prize includes $50,000 for future college studies, a 10-day trip to the Galapagos Islands and a separate trip to visit the CERN particle physics laboratory in Switzerland.

    Girls swept all three age categories in the competition, a contrast to generations past when women were largely excluded from the science world.

    “Personally I think that’s amazing, because throughout my entire life, I’ve heard science is a field where men go into,” Ms. Bose said. “It just starts to show you that women are stepping up in science, and I’m excited that I was able to represent maybe just a little bit of that.” She will start her senior year of high school in the fall.

    “At the end, we were like, ‘Yeah, girl power!’ ” said Naomi Shah of Portland, Ore., who won the age 15-16 category with a study of the effects of air quality on lungs, particularly for people who have asthma. Ms. Shah recruited 103 test subjects, performed 24-hour air quality measurements at their homes and workplaces and had each blow into a device that measured the force of their breath.

    Lauren Hodge of Dallastown, Pa., won the age 13-14 category for research on whether marinades reduce the amount of cancer-causing compounds produced by the grilling of meat. She found that lemon juice and brown sugar cut the level of carcinogens sharply, while soy sauce increased them.

    Vint Cerf, Google’s chief Internet evangelist and one of the judges, said that gender did not play a role in deciding the winners. “This was a gender-neutral evaluation of all the work that was done,” he said. Nonetheless, “I was secretly very pleased to see that happen,” Dr. Cerf said. “This is just a reminder that women are fully capable of doing same or better quality work than men can.”

    The gender tables are not entirely turned among budding scientists. Nowadays the competitors at science fairs are pretty evenly split between boys and girls, both Ms. Bose and Ms. Shah said, and 9 of the 15 finalists in the Google Science Fair were boys.

    “I think that was just, like, pure coincidence,” Ms. Shah said of the girls’ sweep, “because all 15 finalists had great projects.”

    Perhaps belying a bit the notion that American students are falling behind in science, the United States dominated the top slots. All three of the winners were American, as were nearly three-quarters of the finalists. About 60 percent of the entries came from Americans.

    Dr. Cerf said that a common thread among the finalists was that they had explored science enthusiastically for years with the encouragement of their parents.

    For Ms. Bose, it was the blue spinach that got her started. “I actually decided that children didn’t want to eat their vegetables because they were green, and so my fantastic idea for the science fair project was to turn a spinach plant blue,” she recalled.

    She repeatedly injected blue food coloring into a spinach plant, and a few weeks later she took to school a shriveled, stained vegetable — she had forgotten to water it — and explained that children would happily eat spinach if only it were blue.

    “Sounds like a weird beginning, but after that I just realized that science is cool, it’s something I want to do,” said Ms. Bose, who eventually hopes to get a doctorate and a medical degree so that she can both treat patients and look for new cures. “And it’s just been getting better from there.”
