2D Protein Monolayer

Scientists have successfully fabricated a 2D protein monolayer using lysozyme molecules. It serves as a model protein for understanding diseases like Amyloidosis. This research not only paves the way for a more profound comprehension of Amyloidosis but also establishes a versatile platform for probing disease mechanisms. Lysozyme is a naturally occurring enzyme found in various bodily secretions like tears, saliva, mucus. It plays a crucial role in the body’s defence system against bacteria. Amyloidosis is a rare condition characterized by the accumulation of a protein called amyloid in various organs. This buildup can adversely affect the functioning of vital organs such as the heart, kidneys, liver, spleen, nervous system, and digestive tract, ultimately leading to multi-organ dysfunction.

ISRO works on semi-cryogenic engine that uses liquid oxygen kerosene.

ISRO said it is developing a 2,000 kN (kilonewton) thrust semi-cryogenic engine working on a Liquid Oxygen (LOX) Kerosene propellant combination for enhancing the payload capability of Launch Vehicle Mark-3 (LVM3) and for future launch vehicles. Liquid Propulsion Systems Centre (LPSC) is the lead centre for the development of semi-cryogenic propulsion systems with the support of other launch vehicle centres of ISRO. The assembly and testing of the propulsion modules were done at the ISRO propulsion complex (IPRC), Mahendragiri .
