1. Agni P Ballistic missile

News Summary

Defense Research and Development Organisation (DRDO) successfully flight tested a New Generation Nuclear-Capable Ballistic Missile Agni P from Dr. APJ Abdul Kalam island off the coast of Odisha, Balasore at 1055 hrs on June 28, 2021

Prelims GS – Science & Technology

Agni P:
  • Agni P is a new generation advanced variant of the Agni class of missiles.
  • It is a canisterised missile with a range capability between 1,000 and 2,000 km.
  • Agni P is a New Generation Nuclear-Capable Ballistic Missile.
  • The time required to launch the missile is reduced through the canisterisation of missiles besides improving the storage and mobility.

2. Nanochannels and Spintronics

News Summary

Scientists have developed electrically configured nanochannels that can eliminate unwanted energy waste and promise wave-based computing.

Prelims GS – Science & Technology

  • Spintronics is also known as spin electronics.
  • It is the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices offer to harness electron spins.
  • Their collective precession can carry information encoded in its amplitude, phase, wavelength, and frequency without any physical motion of particles.
  • This eliminates unwanted energy waste and promising wave-based computing.
  • Electrically reconfigured parallel nanochannels tune the behavior of spin waves in nano-structure elements.
  • This has been done by periodically tailoring the property that confers a preferred direction on the spin of a system, also called anisotropy using the electric field which is technically called the principles of voltage-controlled magnetic anisotropy.
  • Spin-waves were efficiently transferred through these nanochannels, and this could be switched ‘ON’ and ‘OFF’ and its magnitude altered by a meager voltage of few volts.
  • This can revolutionize on-chip data communication and processing in the future.
