Graphene for UPSC IAS
  • Graphene is composed of a monolayer of closely packed carbon atoms that form a hexagonal honeycomb lattice.
  • It is the building block of Graphite.
  • It is the thinnest, most electrically and thermally conductive material in the world.
  • It is also tremendously strong—about 200 times stronger than steel and flexible, as well as transparent.
  • It is also known as a wonder material due to its vast potential in the energy and medical world.

Applications of Graphene

  • Electronics: It has the potential to create the next generation of electronics like Faster transistors, bendable phones etc.
  • Biomedical: Graphene’s unique properties allow for ground-breaking biomedical applications. Targeted drug delivery, improved brain penetration etc.
  • Battery: Graphene could dramatically increase the lifespan of a traditional lithium-ion battery i.e., devices can be charged quicker – and hold more power for longer.
  • Sensors: Ultra-sensitive sensors made from graphene could detect minute dangerous particles, helping to protect potentially dangerous environments.
  • Graphene Membranes: Graphene oxide membranes are capable of forming a perfect barrier when dealing with liquids and gasses. They have even been proven to stop helium, the hardest gas to block.

Coral Reef

A coral reef is an underwater ecosystem characterized by reef-building corals.

Reefs are formed of colonies of coral polyps held together by calcium carbonate.

Most coral reefs are built from stony corals, whose polyps cluster in groups.

Flash Drought

Flash Drought is the rapid onset or intensification of drought.

A considerably long dry spell with significantly low precipitation anomalies during the monsoon result in an increase in air temperature.

Increased air temperature and precipitation deficit together cause a rapid depletion of soil moisture leading to flash drought.
