Harnessing the power of defects to improve metallic alloys

Two new studies from the Indian Institute of Bombay (IIT Bombay), Mumbai, show the importance of defects in the arrangement of atoms in a crystal, called dislocations, in shaping the physical properties of metallic alloys.

A ventilator can be a life-saver for patients whose lungs are damaged by the COVID-19 infection. But India, like all countries grappling with this pandemic, is likely to face a large shortage of ventilators. Manufacturers are unable to source key components such as sensors and flow controllers from abroad due to the current disruptions in global supply chains.To address this shortage, a team of engineers at the Indian Institute of Science (IISc) is currently building a prototype of an electro-mechanical ventilator from scratch, using only components found or made in India, based on guidelines issued by the UK Medicines and Healthcare Products Regulatory Agency. It is expected to be ready within the next couple of weeks.

Nature is an enigma; an ensemble of complex structures and functions come together to form a variety of mesmerising artefacts, including life. Richard Feynman, the well-known American Nobel Laureate and physicist, famously said—"Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy".
