Lithium-Ion Battery Performance Enhancement Technique
IIT Guwahati researchers have developed a technology to boost the efficiency of rechargeable lithium-ion batteries, which power the majority of today`s portable devices.
Highlights:
♦ The 2019 Nobel Prize in Chemistry was shared by Stanley Whittingham, John Goodenough, and Akira Yoshino for their contributions to the production of lithium-ion batteries.
♦ Most cell phones, smart phones, tablets, laptops, power banks, and other machines use these batteries.
♦ The majority of electric vehicles (EVs) today use lithium-ion batteries, but they are approaching their theoretical limit of 300 watt-hours of electrical energy per kilogramme of energy.
♦ These batteries may also be used to store solar and wind energy, which means that if they are widely used, we can be able to live in a world without using fossil fuels.
New Services of National Internet Exchange of India:
The National Internet Exchange of India has introduced three new programs/services, according to the Ministry of Electronics and Information Technology (MeitY) (NIXI).
Three new services:
♦ IPv6 Expert Group (IP Expert): The team assists all Indian organisations who are having technical difficulties migrating to and adopting IPv6. It will provide services at no cost. The Department of Telecommunications (DOT), MeitY, and industry have collaborated on this project.
♦ NIXI Academy: The NIXI Academy was founded to teach technical and non-technical staff in India how to learn and re-learn IPv6 and other technologies that are not typically taught in educational institutions. Effective candidates will receive an NIXI certificate after passing the test, which will assist them in finding/upgrading jobs in the industry.
♦ NIXI-IP-INDEX: For the Internet world, the National Internet Exchange of India has created an IPv6 index portal. The NIXI-IP-INDEX portal will show the adoption rate of IPv6 in India and around the world.
♦ It can be used to equate the rate of IPv6 adoption in India to that of other countries.
♦ It will also provide extensive details on the Web`s adoption in IPv6, IPv6 traffic, and other topics.
♦ Since 2003, NIXI has been dedicated to spreading Internet infrastructure to Indian people, as specified by Article 8 of the 2013 Companies Act.
Outbreak of Suspected African Swine Fever:
In Mizoram`s Longri area, a suspected outbreak of African swine fever (ASF) has killed 276 domestic pigs. Local authorities banned the purchase and supply of live pigs from the affected areas and the surrounding areas as part of preventative measures.
Highlights:
♦ ASF is a highly infectious and lethal animal disease that usually causes acute hemorrhagic fever in domestic pigs and wild boars.
♦ In the 1920s, it was found in Africa for the first time.
♦ The mortality rate is close to 100%, and because the disease cannot be cured, the only way to stop it from spreading is to cull animals.
♦ ASF is not a threat to humans since it only spreads from one species to another.
♦ “Its extremely high capacity for cross-border transmission puts all countries in the area at risk, once again allowing the spectre of ASF to escape from Africa,” according to the FAO. This is becoming a more significant factor in global food security and household income. Diseases of strategic importance"
###Discovery of Narrow-Line Seyfert 1 Galaxy:
A new active galaxy has been discovered by astronomers. The galaxy was discovered to be the farthest gamma-ray emitting galaxy ever discovered.
Highlights:
♦ The Narrow-line Sever 1 (NLS1) galaxy, which is about 31 billion light-years away, is an active galaxy. It paves the way for the discovery of more gamma-ray emitting galaxies.
♦ Through the Sloan Digital Sky Survey (SDSS), scientists from ARIES, the Autonomous Research Institute of the Department of Science and Technology (DST) of the Government of India, researched around 25,000 luminous active galactic nuclei (AGN) and discovered a unique object. The object emits high-energy gamma rays with a high redshift (greater than 1). They named it as the NLS1 galaxy, which is a peculiar gamma-ray emitting galaxy in space.
♦ For the last 20 years, the SDSS has become the primary optical imaging and spectroscopy study of astronomical phenomena. The University of Chicago founded it.
