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. […]
Optoelectronics
Optoelectronics is the study and application of electronic devices and systems that source, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light. Materials such as tungsten diselenide (WSe2) and molybdenum diselenide […]
Artificial gravity
A team from the University of Colorado is working on making a device which could create artificial gravity in space Artificialgravityis a force that simulates the effect of gravity in a spaceship. It is not caused by the attraction to the Earth but is instead caused by acceleration or centrifugal force. Artificial gravity or rotational gravity is thus the appearance of […]
Short Wave Transmission
Prasar Bharati has asked All India Radio to come up with a proposal to phase out Short Wave (SW) transmitters. About SW: Shortwave radio is radio transmission using shortwave radio frequencies, the range always includes all of the high frequency band (HF), and generally extends from 3-30 MHz (10 to 100 meters), above the medium […]
