New Delhi :
Researchers of Indian Institute of Technology, Guwahati (IIT Guwahati) has developed a method to transform industrial waste into valuable chemicals. Researchers formulated efficient ‘pincer’ catalytic systems for the same.
The conversion of valuable intermediates –
Tiny amounts of these “pincer catalysts” repeatedly convert large amounts of industrial waste such as glycerol into lactic acid and hydrogen. Such catalysts also efficiently convert bioethanol, a low-energy density fuel, into high-energy density butanol. The conversion of valuable intermediates such as glycerol and ethanol, produced during the processing of biomass, into industrially useful chemicals has elicited much interest worldwide.
Various types of pincer ligands that are –
IIT Guwahati The pincer ligand is most often an anionic, two-electron donor to the metal centre. It consists of a rigid, planar backbone usually consisting of aryl frameworks and has two neutral, two-electron donor groups at the meta-positions.There are various types of pincer ligands that are used in transition metal catalysis.

Can be transformed into lactic acid and hydrogen –
This can be more understood as, Glycerol, which is a by-product in biodiesel production, can be transformed into lactic acid and hydrogen – the former is extensively used in food, pharmaceutical, cosmetic and polymer industries, and the latter in the energy sector. Similarly, ethanol obtained from biomass can be converted into high quality fuel. Bioethanol, which has lower energy density than gasoline and corrodes engine parts when used directly, can be transformed into higher energy butanol that is non-corrosive in nature.
Dr Srivastava who is the part of the leading team says, “Our computational studies have attributed the unprecedented activity of the pincer catalysts to the minimal crowding present at the metal centre and have enabled good understanding of the electronic and steric (crowding) factors that control reactivity.”
Research will have global impact on production of biofuels –
The research team has been led by IIT Guwahati professors, Dr Akshai Kumar, Alape Seetharam and Dr Hemant Kumar Srivastava. Researchers formulated efficient ‘pincer’ catalytic systems that can transform industrial wastes to useful chemicals. This research will have global impact on production of biofuels & help the environment.

UP Govt notifies guidelines to reopen universities and colleges from November 23
Uttar Pradesh Government has notified guidelines to reopen universities, colleges from November 23 after the Government of India has allowed to reopen colleges but with the permission of state governments only. “Universities and degree colleges across UP will reopen from November 23 but only with 50% attendance of students on roaster basis,” an official said.
Higher educational institutions were asked to resume classes –
The state government on Tuesday notified the guidelines for reopening of the universities and colleges, which have been closed since March in view of the Covid-19 pandemic- a gap of more than 8 months. The higher educational institutions were asked to resume classes in a phased manner to avoid crowding on campuses, said additional chief secretary, higher education, Monika Garg in her order sent to all district magistrates and registrars of universities.
