ARCI developed technology to improve fuel efficiency of internal combustion engines:
International Advanced Centre for Powder Metallurgy & New Materials (ARCI) developed ultrafast laser surface texturing technology. The technology can improve the fuel efficiency of internal combustion engines.
Highlights:
♦ Laser surface micro-texturing offers precise control of the size and shape.
♦ The density of micro-surface texture features gains momentum as a way to control friction and wear.
♦ The special feature of the technology is a pulsating laser beam creates micro-dimples or grooves on the surface of materials in a very controlled manner.
♦ The texture traps wear debris when operating under dry sliding conditions. It provides effects like enhancing oil supply that can lower friction coefficients and may enable reduced wear rate. This will improve the fuel efficiency of internal combustion engines.
India to begin coronavirus antibody tests:
India is expected to begin coronavirus antibody tests to confirm whether a person has been previously infected with the virus. The change is intended to help you understand the country`s COVID-19 epidemiology.
Highlights:
♦ The antibody test is named as "serological test".
♦ The test looks for antibodies in the blood, it is different from the current, diagnostic tests that determine active infection through nasal or throat swabs.
♦ Serological tests will help the scientists and doctors to determine if a person has previously had a viral infection, based on the presence of antibodies in the blood, possibly even if they were asymptotic.
♦ It is not a confirmatory test. It will be used for the purpose of surveillance to generate data and understand whether people got exposed to the virus.
