Notes:
Using platinum nanocatalyst, a two-member team at the IIT Madras has successfully converted petroleum waste-product toluene into benzoic acid. Benzoic acid is used as a food preservative (E210) and medicine for fungal/bacterial infection. Toluene is converted into benzoic acid through selective and controlled oxidation in the presence of a catalyst — binaphthyl-stabilised platinum nanoparticles (Pt-BNP). Generally, organic reactions are carried out using organic solvents, which makes it expensive and also generates toxic waste. So, the team led by G. Sekar used water as solvent to make it environment-friendly. Also, a green oxidant (70% aqueous tert-butyl hydroperoxide or TBHP) is used for converting toluene into benzoic acid. When toluene is oxidised, it gives four products. But, the team used catalyst that they developed and then only benzoic acid is produced. No alcohol, aldehyde or ester is produced. The yield of benzoic acid varied from 68-96% depending on whether the toluene used is electron-deficient or electron-rich.

Notes:
The Government of India (GoI) has constituted a tribunal to adjudicate if there exists sufficient cause to ban the Jamaat-e-Islami Jammu and Kashmir (JeL) and the Jammu and Kashmir Liberation Front-Yasin Malik (JKLF-Y) faction. The tribunal will be headed by Justice Chander Shekhar of the Delhi High Court. The decision has been taken by the Union Home Ministry exercising the powers conferred under the Unlawful Activities (Prevention) Act of 1967. The JeI and the JKLF-Y were declared as unlawful associations on February 28 and March 22 respectively.

Batman will be first inductee into the Comic-Con Museum’s Character Hall of Fame. The honor was announced during the “Happy Birthday Batman!” panel at WonderCon on March 30, when Batman turned 80. The ceremony will take place at the Federal Building in San Diego’s Balboa Park — which is the future site of the Comic-Con Museum, on 17th July 2019. The ceremony will be accompanied by an exhibit of Batman-themed memorabilia and related props and will feature appearances by celebrities and creators whose careers have interacted with the Dark Knight across the years. Batman first appeared in the ‘Detective Comics No. 27’ published on March 30, 1939, created by Bob Kane and Bill Finger.

Notes:
Researchers led by Kavli Institute for the Physics and Mathematics of the Universe in Japan has put a theory speculated by the late Stephen Hawking to its most rigorous test to date, and their results have ruled out the possibility that primordial black holes smaller than a tenth of a millimeter make up most of dark matter. They used the gravitational lensing effect to look for primordial black holes between Earth and the Andromeda galaxy. However, gravitational lensing effects are very rare events because it requires a star in the Andromeda galaxy, a primordial black hole acting as the gravitational lens, and an observer on Earth to be exactly in line with one another. In order to maximise the chances of capturing an event, the researchers used the Hyper Suprime-Cam digital camera on the Subaru telescope in Hawaii, which can capture the whole image of the Andromeda galaxy in one shot. Taking into account how fast primordial black holes are expected to move in interstellar space, the team took multiple images to be able to catch the flicker of a star as it brightens for a period of a few minutes to hours due to gravitational lensing. The team’s results showed primordial black holes can contribute no more than 0.1% of all dark matter mass. Therefore, it is unlikely the theory is true.

Notes:
South Korea will launch the world’s first fully-fledged 5G mobile networks on 5th April 2019. Hyper-wired South Korea has a reputation for technical prowess, and Seoul has made the 5G rollout a priority as it seeks to stimulate stuttering economic growth. The superfast communications heralded by fifth-generation wireless technology will bring smartphones near-instantaneous connectivity – 20 times faster than the existing 4G. It is crucial for the future development of devices ranging from self-driving vehicles that send data traffic to one another in real time, industrial robots, drones and other elements of the Internet of Things. 5G’s hyper speed can connect one million devices within a one square kilometre zone simultaneously. Until now, no mobile networks have offered nationwide 5G access. Japan is expected to roll out a limited deployment in 2019 before full services start in time for 2020 Tokyo Olympics.

Notes:
On March 28, President Ram Nath Kovind became the first-ever Indian President to visit Bolivia. Here, President Evo Morales Ayma conferred the highest State Honour of Bolivia – Condor de los Andes en el Grado de Gran Collar – on President Kovind. Both the countries have agreed to facilitate Bolivian supplies of lithium Carbonate to India and foster joint ventures for Lithium battery / cell production plants in India. This move will make Bolivia, which is known to have one-fourth of the world’s lithium reserves, one of the major provider of metal for India’s e-mobility and e-storage needs. To mark the 150th Birth Anniversary of Mahatma Gandhi, India offered two busts of Gandhiji to Bolivia. The Bolivian side accepted the offer and is likely to place the busts in its capital La Paz and its largest city Santa Cruz. This South American nation has also joined the International Solar Alliance (ISA) by signing the framework agreement on ISA. In a total, India and Bolivia have signed 8 MoUs in various fields of mining, space, traditional medicine during President’s Kovid three day visit to the country.

Notes:
