Current Affair 1:
Management & Entrepreneurship and Professional Skills Council (MEPSC)
Why this body?
The Council is being driven by senior industry leaders and seasoned professional leaders.
Current Affair 2:
What are aerogels?
Their graphene-modified silica aerogel can remove over 76% of pollutants (parts per million level) when water is flowing, making it possible to scale up the experiment, researchers said.
Aerogels are among the lightest solid materials known to man. They are created by combining a polymer with a solvent to form a gel, and then removing the liquid from the gel and replacing it with air. Aerogels are extremely porous and very low in density. They are solid to the touch. This translucent material is considered one of the finest insulation materials available.
Since their invention, aerogels have primarily been made of silica. The silica is combined with a solvent to create a gel. Silica-based aerogels are very light, as they are about 95% porous. Silica aerogels are very useful, but they have limitations—they are very fragile.
Current Affair 3:
A new mushroom species from the Western Ghats
A tiny, fragile-looking mushroom sporting a honey-yellow ‘cap’ found on the campus of the Jawaharlal Nehru Tropical Botanic Garden and Research Institute (JNTBGRI) at Palode here has been identified as a new species.
Researchers at the JNTBGRI identified and described the new species as belonging to the genus Candolleomyces, a relatively small genus with just 35 species recognised worldwide.
Current Affair 4:
Nanophotonic electron accelerator (NEA)
What are particle accelerators?
It is a device that accelerates charged particles, such as electrons or protons, to very high speeds and energies. These accelerated particles are then used for various scientific and practical purposes, including fundamental research in particle physics, medical treatments, and industrial applications.
These are powerful scientific instruments that accelerate charged particles, such as electrons or protons, to extremely high speeds and energies.
However, these machines are typically massive and demand extensive spaces within research facilities. To address this issue, physicists have created the world's tiniest particle accelerator.
Developed by the Friedrich-Alexander University of Erlangen–Nuremberg (FAU) in Germany, this miniature particle accelerator is roughly the size of a small coin.
This technology employs nanophotonic principles, a field that deals with the interaction of light and matter on the nanoscale, to create ultra-miniaturized accelerators.
The nanophotonic electron accelerator’s main acceleration tube is incredibly small, measuring merely 0.02 inches (0.5 millimeters) in length. It is reportedly 54 million times shorter than the ring-shaped tunnel that forms the Large Hadron Collider (LHC) at CERN in Switzerland. The LHC is the world's largest and most powerful particle accelerator, with a circular ring spanning 16.8 miles (27 kilometers).
