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. […]
Hyperloop
What is Hyperloop Technology? Theoretical concept of hyperloop is mooted by maverick techno-entrepreneur Elon Musk in 2013. Hyperloop technology promises to move people and goods through low-pressure tubes far faster than commercial air travel, within earthly confines, of course. In hyperloop transportation, custom-designed capsules or pods are expected to zip smoothly through continuous steel tubes which are […]
5G Technology
Essentially, 5G is a set of technical ground rules. They define the workings of a cellular network, including the radio frequencies used and how various components like computer chips and antennas handle radio signals and exchange data. What are the advantages? Speed – The speed depends on where one is, and which wireless services is used. […]
