Detecting explosives using chemical compounds

Molecules made of a metal ion attached to an organic compound can be used to detect explosives made of nitroaromatic compounds, like picric acid and trinitrotoluene (TNT). With further research, these can go on to replace the conventional metal detectors we all walk through in airports and malls. Bappaditya Gole and others from P S Mukerjee’s research group in the department of Inorganic and Physical Chemistry have been involved with developing a metal-organic combination that can detect nitroaromatic compounds efficiently. The research project has been published in a series of three papers in the international journal, Chemistry: A European Journal.

IISc Professor wins DRDO Academy Excellence Award

Prime Minister Narendra Modi gave away a series of awards at the Defence Research and Development Organisation (DRDO), in the presence of Defense Minister Arun Jaitley and a host of other dignitaries. Academy Excellence Awards were presented to Professor S Mohan, a Visiting Professor at the Centre for Nanoscience at IISc and Prof Kamakoti from IIT Chennai.

Photons take a detour

Researchers have proposed an experiment to show that, sometimes, photons may choose longer paths over the shorter ones. Though this result may look too simple, it is expected to influence physics over a large scale: from the way quantum mechanics is introduced to students to better understanding of quantum computing applications.

Software for managing Bengaluru's water supplies

A state of the art water management system, which can change how the water supply in the city is managed, is now ready for Bengaluru. Researchers at IISc, in collaboration with IBM and Bengaluru Water Supply and Sewage Board (BWSSB), presented the software at the 12th International Conference on Computing and Control for the Water Industry in Italy. The proceedings have been published in the international journal Procedia Engineering.

17 new species of geckos from the Himalayas

The number of species of bent toed geckos in the Himalayas has gone up from five to about seventeen, a new study has revealed. The geckos, belonging to the genus Cyrtodactylus, are distant relatives of the common house gecko that adorns our walls.

Overcoming barriers to effective Hepatitis C treatment

Among viruses, the Hepatitis C virus is extremely persistent – a patient sometimes cannot get rid of the virus after infection, and it remains in their cells over long periods of time. The standard HCV treatment is effective over time only in half the patients, making Hepatitis C the bane of doctors and scientists worldwide. Researchers at the Therapeutic Engineering Lab at the Department of Chemical Engineering, Indian Institute of Science, think they may know more about why the disease is persistent. Using simulations, they found that the Hepatitis C virus and the body’s immune system get into a deadlock when the body is fighting the virus.

Classifying agricultural land into crop types using satellite images

Looking at satellite images of an area and being able to tell what crop is being grown, will be a great resource to improve agricultural productivity. Though satellite images show crop growth from planting to harvest and abnormalities, using them to identify crop type accurately is a challenging problem.

Antiviral properties of pomegranate peel extract

The hepatitis C virus is one of the main causes of chronic liver disease, which can lead to liver fibrosis, cirrhosis and hepatocellular carcinoma. Around 170 million people are infected with the virus worldwide. Compounds isolated from the extract of Pomegranate peel inhibit the growth of the hepatitis C virus (HCV), a recent study has found.
