Scientists Use a Sweetener to Make Materials for Bone Reconstruction

A team of researchers from the Indian Institute of Science, Bangalore, has developed a novel polymer that can accelerate healing of bone fractures. Dr. Kaushik Chatterjee, Assistant Professor in the Department of Materials Engineering in collaboration with Professor Giridhar Madras from Chemical Engineering at IISc are working on developing polymers that can serve as templates to facilitate bone growth. The team is working on developing maltitol-based biodegradable polyesters for accelerated healing.

A reactor to produce graphene, Made In India

Indian Institute of Science and KAS Tech have together developed India's first commercially available, graphene producing system. The Centre for Nano Science and Engineering (CeNSE), IISc developed the technology, and working together with KAS Tech, a Bengaluru based manufacturing company, they transformed the lab prototype into a commercial product. The product was launched during the recently held Bangalore INDIA NANO.

Technology transfers from a lab in CeNSE, IISc

Designing the world’s smallest speakers that are inspired by the chirping of crickets, writing some of the tiniest metal patterns in a frugal way and mechanically detecting cancer in living cells are some of the most exciting technology transfers brewing from one lab in the Centre for Nanoscience and Technology, Indian Institute of Science.

This Ultralight Foam Might Save Your Life

Nitrogen dioxide is toxic to humans when inhaled. Unfortunately, our noses get anaesthetised when exposed to low levels of nitrogen dioxide. This prevents us from sensing the otherwise acrid gas, creating a possibility for overexposure with harmful effects on health. This may lead to poisoning of the lung, which in some cases might prove to be fatal.

Lab Story: Imitating nature’s nano-machines: Optics, Nanostructures and Quantum fluids Lab

In 1959, physicist Richard Feynman, in his talk “There’s plenty of room at the bottom”, envisioned a future where we could engineer materials and devices from bottom up, by directly manipulating individual atoms. This field is now known as Nanotechnology. It involves developing devices and materials on a nanoscale, which is a just a billionth of a metre, a concept that nature seems to have perfected. From the nano-sized hair on a lizard’s feet that helps it grip vertical walls, to the nanostructures on a butterfly’s wing which create its appealing colours and the flagella on bacteria which assist in their movement, are all examples of nature using nanotechnology. Although humanity is yet to achieve the level of complexity we see in nature, recent advances in the field, some by imitating nature, have had an enormous impact, especially in the fields of technology and medicine. The idea of building helical nanostructures and then using them as propellers on tiny robots swimming inside the human body or blowing electron bubbles from a two dimensional sheet of electrons may sound futuristic, but this is the kind of research happening in the Optics, Nanostructures and Quantum fluids lab at the Indian Institute of Science (IISc).

Researchers at IISc fabricate the best hydrogen gas sensor in the world

“When hydrogen gas comes in contact with air, it becomes a bomb.” says Prof. Navakanta Bhat from the Centre for Nano Science and Engineering, and Department of Electrical Communication Engineering at the Indian Institute of Science (IISc). Hydrogen gas sensors have made it possible to detect leaks and maintain high levels of safety. Prof. Bhat and his group of scientists at IISc have succeeded in designing the best hydrogen gas sensor known till date.

Powering Electronic Devices Through a Mercury Droplet

Researchers at the Indian Institute of Science (IISc) have designed a new type of energy harvester that can scavenge electrical energy from weak vibrations. Vibration drives a liquid droplet and the motion of the liquid droplet produces electrical energy which can power portable electronic devices efficiently.
Conventional sources of energy are precious and they are getting exhausted at a very rapid pace. Scientists are looking for alternative sources of energy, like solar energy, wind energy, energy from bio waste etc., to replace the conventional sources. “Energy harvesting” is the conversion of unusual forms of energy, like heat, wind, vibration etc., which are otherwise wasted, into some usable form of energy. Efficient energy harvesting is the key to addressing our ever-increasing energy problem.
