Protecting organic devices against water vapour is a concern for many scientists. Organic devices are known to be highly reactive to atmospheric water vapour, a significant cause for their premature degradation. A successful solution was generated by a team of four researchers at the Department of Chemical Engineering in IISc. Using a polymeric nanocomposite, they have devised an efficient and economical barrier to protect organic devices.

IISc researchers have successfully found a way to navigate tiny, geometrically identical filaments, and subsequently place them at predefined positions with respect to each other. The method works without any physical contact with the filaments, and this can have important applications in nanomedicine.
Researchers at the Indian Institute of Science, Bangalore have now devised a technology which can efficiently extract energy from vibrations that are almost always present around us. Though not from thin air, this development has a wide scope of applications and could power smalls LED lights, fire and smoke alarms, biomedical devices to name a few.
Researchers from the IISc have developed a new way to design thin, porous membranes that can be used for water filtration. By carefully mixing two polymers, and adding some nanostructures, they obtained membranes with ultra small holes in it. They have also shown that these membranes are more efficient in killing the bacteria commonly found in drinking water.
One possible means of bridging the gap between India’s abundant, varied natural resources and her ever-increasing requirements like clean water, food and rapid, low cost diagnostic machinery is the use of nanotechnology, write Arindam Ghosh and Yamuna Krishnan in the international journal Nature Nanotechnology.
