Indian Navy Steps Up Anti-piracy Patrol

• The Navy deployed its P-8I long-range maritime surveillance aircraft for anti-piracy sorties from Salalah in Oman to patrol the Gulf of Aden under its Mission Based Deployments (MBD) in the Indian Ocean Region (IOR),
• Under the MBD concept, the Navy maintains a ship at every choke point in the IOR at any point of time.

P-8I Aircraft

The P-8I is a long-range anti-submarine warfare, anti-surface warfare, intelligence, surveillance and reconnaissance aircraft capable of broad-area, maritime and littoral operations.

IIT Madras Develops New Material

• Recently, Indian Institute of Technology (IIT) Madras has developed a material with properties suitable for quantum optoelectronics.
• The materials like tungsten diselenide and molybdenum diselenide were being studied for their opto-electronic properties – a combination of optics and electronics.
• Researchers from IIT Madras have found a way of enhancing this property of these materials about 30 times in tungsten diselenide, by drop-casting gold nanoparticles on to a two-dimensional film.
• A key property of these materials is photoluminescence which can be used in various devices such as quantum LEDs which can be used in communication and computation.

Photoluminescence: Photoluminescence is a process in which a molecule absorbs a photon in the visible region, exciting one of its electrons to a higher electronic excited state, and then radiates a photon as the electron returns to a lower energy state.

Optoelectronics: Optoelectronics concerns the study and application of electronic devices that source, detect and control light.
