IIT Mandi develops environmentally safe and cost efficient catalysts

New Delhi :

Indian Institute of Technology (IIT) Mandi researchers has developed a carbon based nanosheet that can be used as environmentally safe and cost efficient catalyst that enables industrial hydrogenation reactions. The environment-friendly nanosheet can replace precious heavy metals currently in use, bringing down the process’ cost.

What is Hydrogenation? –
Hydrogenation is a process of adding hydrogen to a compound which is commonly used in industries to produce aromatic alcohols for perfumes, pharmaceutical products, agrochemicals and other chemical substances. Instead of using hydrogen gas, which can be inconvenient and expensive, industries use hydrogen donor chemicals that release hydrogen for the reaction. However, a catalyst is needed for the completion of the reaction.

What is a Catalyst? –
A catalyst is a compound that increases the rate of a reaction without getting consumed in the process. For hydrogenation, industries currently use precious metals such as rhodium, iridium, platinum and ruthenium that are expensive and lead to environmental pollution. The recovery of these metal catalysts is also difficult.

Researchers team includes-
The team from the School of Basic Sciences at IIT Mandi, in collaboration with researchers from IIT Ropar, have carried out these experiments.

The team tried various hydrogenation reactions using the carbon-based catalyst and found it produced high yields for these reactions, proving it to be versatile. In addition, these nanosheets can be recovered and reused for several runs without any loss in catalytic activity.

Education Minister Tweeted –
Dr. RP Nishank, Union Minister for Education on this new experiment congratulated the team members. He on his official Twitter handle wrote, “.@iit__mandi has developed a carbon-based nanosheet that can be used as a catalyst for industrial hydrogenation reactions. The environment-friendly nanosheet can replace precious heavy metals currently in use, bringing down the process’ cost.”

IIT Kharagpur launches Telemedicine System to provide Healthcare Support at Patient’s Doorstep

New Delhi :

Indian Institute of Technology (IIT) Kharagpur researchers has launched telemedicine software ‘iMediX’ which will provide critical healthcare support to patients at their doorstep. The patients will receive a consultation by physicians without having to go to the hospitals and clinics.

Standard internet browser –
The system iMediX which is accessible by any standard internet browser has been developed by the researchers at IIT Kharagpur Department of Computer Science and Engineering, said an Institute Spokesperson. This software provides with the facility to the patient to sign up and get an account by filling details like Email ID and their Contact Number. The patient can make a request for consultation by choosing a department of the hospital, entering their chief complaints and uploading necessary scanned medical records. The hospital administration processes the request and assigns a doctor. The doctor after logging in sets an appointment date and time for the patient and the system communicates the information to the patient by mail and SMS.
