Reply by the Central Pollution Control Board (CPCB) in compliance to the National Green Tribunal (NGT) order dated January 21, 2024 in the matter of ‘News item titled “Feeling anxious? Toxic air could be to blame” appearing in Times of India dated 10.10.2023’. NGT had directed CPCB to file a …
Using mercury nanotubes india may be able to produce solar cells with a greater capacity to absorb solar energy. The secret behind this extra capacity lies in mercury compound nanotubes, scientists at iit Delhi have found out. Nanotubes, because of their structure, exhibit electrical and optical properties, which help in …
Nanotechnology can be risky, but no one is regulating its use Thanks to nanotechnology, that allows grinding particles to atomic levels, you now have face creams that spread so smoothly on your skin that only a transparent sheen is visible, no layers. While that seamless make-up is desirable, cosmetics using …
Technological innovation vital for wealth generation, said University of Surrey Advanced Technology Institute Director Professor Ravi Silva. He was addressing a workshop on Exploring Opportunities in Nanoscience and Nanotechnology organised by the Postgraduate Institute of Science (PGIS), University of Peradeniya and the Institute of Engineers, Sri Lanka, in collaboration with …
Holistic understanding of nanotechnology using systems analysis tools is essential for evaluating claims about the potential benefits of this emerging technology. This article presents one of the first assessments of the life cycle energy requirements and environmental impact of carbon nanofibers (CNFs) synthesis. Life cycle inventory data are compiled with …
Researchers in the United States announced on Friday they had created a paper-like membrane made of nano-scale materials that could clean up oil pollution and other chemical spills. The substance can absorb up to 20 times its own weight in oil and be recycled again and again for future use, …
Norwegian-born philanthropist Fred Kavli awarded seven scientists his first batch of $1 million prizes for astrophysics, neuroscience and nanotechnology on Wednesday. Kavli, a physicist who left Norway in 1955 with $300 and turned it into a $340 million fortune in California, set up the prize for advances in research ranging …
Could nanotechnology revive an old killer? That's the fear being raised by the discovery that carbon nanotubes shred the lung lining in a similar way to asbestos fibres. Ken Donaldson at the University of Edinburgh, UK, and colleagues injected carbon nanotubes into the abdominal cavity of mice. One week later, …
there is help at hand for those undergoing bone implants. A new and stronger material paves the way for better recovery after knee or hip surgeries. Researchers from the Department of Chemistry at iit, Chennai, have developed a biocompatible and easy-to-produce nanocomposite
Cornell, Stanford and Texas A&M; universities each will receive grants of $20 million to $25 miliion from a new Saudi Arabian research institution to study nano materials solar energy and computational science. The grants come from King Abdullah University of Science and Technology or KAUST a graduate-level research school set …
scientists have designed a method that may make production of aroma in fruits easier, and also cheaper. Alternatively, the product can also be used to get rid of impurities in insulin made in a laboratory, or recombinant protein (produced artificially), as it is termed. So, what is the product? It …
Barry Castleman, an environmental consultant and expert on workplace health hazards, tells Arnab Pratim Dutta about nanotechnology's impacts We hear about nanotechnology everywhere but we seldom hear of its impacts. Is it good or bad? We are just beginning to understand the nature and the extent of adverse effects that …
a new nanowire promises to revolutionalize the world of nanotechnology. Developed by scientists at Harvard University, the wire, which is a fraction of the width of human hair, will function as a solar cell, generating power for its own use, and other nanodevices. Scientists say the nanowire is more efficient …
Despite criticism by ngos and consumer groups, the us food regulator has announced that cosmetics, drugs and other products that use nanotechnology will now not require special regulations or labelling. A task force of the us Food and Drug Administration (fda) concluded that although nano-sized materials may have completely different …
singing iceberg: Scientists monitoring earth movements in Antarctica believe they have found a singing iceberg. Sound waves from the iceberg had a frequency of around 0.5 Hertz, too low to be heard by humans, but by playing them at higher speed, the iceberg sounded like a swarm of bees or …
