Ultra-Thin Heteroprotein Films
Consider the following statements:
- Recently, Indian scientists developed ultra-thin heteroprotein films which can pave the way for expanding applications of thin films in biomedical and food packaging industries.
- The ultrathin monolayer protein films consist of two globular proteins: bovine serum albumin (BSA) and lysozyme (Lys).
- The scientists used the Langmuir-Blodgett (LB) technique which gives the films thickness in the order of nanometer.

VL-SRSAM
Consider the following statements:
- Recently, the Vertical Launch Short Range Surface to Air Missile (VL-SRSAM) was successfully flight-tested by Defence Research & Development Organisation (DRDO) and the Indian Navy.
- It is meant for neutralising various aerial threats at close ranges including sea-skimming targets.
- The VL-SRSAM system has been designed to strike at the high-speed airborne targets at the range of 200km to 300km and at an altitude of around 15km.
