Belle – II
It is an experiment carried out by The High Energy Accelerator Research Organisation, Japan to study violations of the standard model and dark matter. It has a highly sensitive particle detector which has better sensitivity, higher than its predecessor, Belle. Complementary to the direct search experiments being carried out at the Large Hadron Collider in CERN, Belle-II […]
Quantum supremacy
It is a term proposed in 2012 by John Preskill, professor of theoretical physics at the California Institute of Technology. It describes the point where quantum computers can do things that classical computers cannot. In Google’s case, researchers at the University of California, Santa Barbara have claimed to have developed a processor that took 200 seconds to do a calculation that […]
Lithium-ion batteries
Nobel Prize in chemistry 2019 awarded for work on lithium-ion batteries About The first rechargeable battery came about in 1859. These were made from lead-acid, and are still used to start gasoline- and diesel-powered vehicles today. Stanley Whittingham discovered an extremely energy-rich material, which he used to create an innovative cathode in a lithium battery. This battery was made from titanium […]
Lithium-Sulfur Battery
Researchers who have developed this new Li-S battery claim it has an “ultra-high capacity” and has better performance and less environmental impact. This means that they may be able to outperform the Li-ion batteries by more than four times. With Li-ion batteries, some disadvantages include their susceptibility to overheating and their being prone to damage […]
Biorock or mineral accretion technology
What is Biorock? It is the name given to the substance formed by electro accumulation of minerals dissolved in seawater on steel structures that are lowered onto the sea bed and are connected to a power source, in this case solar panels that float on the surface. How they are formed? The technology works by passing a […]
TYRE PYROLYSIS
About: What is it? Tyre pyrolysis refers to a technique of breaking down used tyres in the absence of oxygen. Shredded tyres, at temperatures between 250º C and 500º C, produce liquid oil and gases. NGT Ruling (2014): The National Green Tribunal in 2014 prohibited used tyres from being burnt in the open or being used as […]
TechSagar
It is a platform to discover India’s technological capability through a portal. It is a consolidated and comprehensive repository of India’s cyber tech capabilities which provides actionable insights about capabilities of the Indian Industry, academia and research across 25 technology areas like internet of things (IoT), Artificial Intelligence (AI), Machine Learning (ML), blockchain, cloud & […]
Elastocaloric Effect
When rubbers bands are twisted and untwisted, it produces a cooling effect. This is called the “elastocaloric” effect, and it has been suggested that it can be used in a very relevant context today. How will it work in a fridge? Researchers have found that the elastocaloric effect, if harnessed, may be able to do away […]
Indigenous Fuel Cell System
On the occasion of the Council of Scientific and Industrial Research (CSIR) Foundation Day, the President of India recently introduced India’s first indigenously developed high-temperature based Fuel Cell System. It is developed under the Public-Private Partnership (PPP) model by the Council of Scientific and Industrial Research (CSIR) in partnership with Indian industries. It is built under India’s flagship programme named ‘New Millennium Indian […]
Hydrogen-powered vehicles over Electric vehicles
China, Japan and South Korea have set ambitious targets to put millions of hydrogen-powered vehicles on their roads. But, Hydrogen fuel cell vehicles (FCVs) have been upstaged by electric vehicles (EVs). It becomes a mainstream option due to the success of Tesla Inc’s luxury cars as well as sales and production quotas set by China. […]
