Indian scientists decode new class of materials for energy harvesting, power generation

New Delhi, June 20 (IANS) Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) Bengaluru, an autonomous institution under the Department of Science & Technology (DST), on Thursday provided groundbreaking insights into a new class of materials for energy harvesting and power generation.

Their work unraveled the electronic mechanisms governing chemical bonding of new class of materials called incipient metals with metavalent bonding (MVB) within a single 2D layer of Group IV “chalcogenides” that can boost energy harvesting and power generation.

Chalcogenides can transition reversibly between amorphous and crystalline phases in response to changes in temperature, pressure or electrical fields.

The study by Professor Umesh Waghmare from Theoretical Sciences Unit at JNCASR, explored the possibility of introducing the metavalent bonding (MVB) within a single 2D layer of Group IV chalcogenides, investigating its mechanisms and the resulting consequences on material properties.

“These materials, termed incipient metals, possess a combination of properties that defy conventional understanding. They exhibit electrical conductivity akin to metals, high thermoelectric efficiency characteristic of semiconductors, and unusually low thermal conductivity, creating a triad of properties that cannot be explained by traditional chemical bonding concepts,” explained Professor Waghmare.

The study, published in Angewandte Chemie International Edition and supported by JC Bose National Fellowship of the Science and Engineering Research Board-DST and JNCASR research fellowship, provides a first-principle theoretical analysis focusing on the bonding nature within five different 2D lattices of Group IV chalcogenides.

This category includes compounds which exhibit remarkable properties, transitioning reversibly from a glassy amorphous structure to a crystalline form in less than 100 nanoseconds when subjected to heating or cooling.

Driven by an idea presented by Professor CNR Rao, the study aimed to unravel the electronic mechanisms governing the chemical bonding in these materials.

The findings, which took nearly two years of theoretical and computational work, have shed light on the unique properties of these materials, challenging conventional chemical bonding ideas.

 long surgery in Kerala

New Delhi, July 25 (IANS) A team of doctors in Kerala performed a five-hour heart transplant operation, giving a new lease of life to a 13-year-old girl suffering from severe cardiomyopathy — a disease of the heart muscle.

The procedure was carried out at the Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), an autonomous institute under the Department of Science and Technology (DST). Paediatric heart transplants are rare due to the limited availability of donor hearts and high costs, making such treatment inaccessible to many.

The young patient had been on a ventilator for two months, confined to the ICU.

The breakthrough came when the Kerala State Organ and Tissue Transplant Organisation (K-SOTTO) allocated a donor heart to SCTIMST.

The organ came from a 47-year-old school teacher declared brain dead following a ruptured intracranial aneurysm at KIMSHEALTH hospital. The Kerala Police facilitated a green corridor to ensure the swift transport of the organ.

A multidisciplinary team led by Baiju S Dharan, from the Department of Cardiovascular and Thoracic Surgery performed the complex operation.

Agricultural pesticide may pose cancer risk as bad as smoking: Study

New Delhi, July 25 (IANS) While pesticides are essential for ensuring high crop yields and food security, they also increase the risk of cancer akin to smoking, finds a study.

The research published in the journal Frontiers in Cancer Control and Society found that even non-farmers living in areas with heavy agricultural activity are exposed to many pesticides.

The study revealed that in such environments, the impact of pesticide use on cancer incidence rivalled that of smoking, particularly for non-Hodgkin lymphoma, leukaemia, and bladder cancer.

“In our study, we found that for some cancers, the effect of agricultural pesticide usage is comparable in magnitude to the effect of smoking,” Isain Zapata, associate professor at the Rocky Vista University College of Osteopathic Medicine in Colorado, US.

“We present a list of major pesticide contributors for some specific cancers, but we highlight strongly that it is the combination of all of them and not just a single one that matters,” Zapata emphasised.

The study included data on 69 pesticides from the US Geological Survey, acknowledging that people are generally exposed to a “cocktail” of pesticides rather than just one.

This comprehensive evaluation marks the first large-scale study to assess cancer risk from a population-based perspective, comparing it with a well-established risk factor like smoking.

Zapata noted the importance of considering the broader impact of pesticide use, including geographic factors. For example, regions like the Midwest, known for corn production, showed more pronounced associations between pesticide exposure and cancer incidence.

The study aims to raise awareness of the risks posed by pesticide use, even for those not directly involved in agriculture.
