The issue in news

The Income Tax Department launched the Faceless Income Tax Appeals.

Main points

  • Under Faceless Appeals, all Income Tax appeals will be finalised in a faceless manner under the faceless ecosystem with the exception of appeals relating to serious frauds, major tax evasion, sensitive & search matters, International tax and Black Money Act.
  • From now on, in income tax appeals, everything from e-allocation of appeal, e-communication of notice/questionnaire, e-verification/e-enquiry to e-hearing and finally e-communication of the appellate order – the entire process of appeals will be online, dispensing with the need for any physical interface between the appellant and the Department.
  • There will be no physical interface between the taxpayers or their counsel/s and the Income Tax Department. The taxpayers can make submissions from the comfort of their homes and save their time and resources.


  1. Graphene

The issue in news

A new low-cost method of upscaling most conductive material ‘graphene’ developed.

About the Study:

  • Researchers from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute under the Department of Science & Technology, Government of India, through their recent research work have upscaled graphene production while retaining its thin layered properties.
  • The researchers used a combination of two techniques to understand and quantify how much single layer like behaviour exists in the graphene system.
  • Raman spectroscopy – a technique to understand whether a graphene species has single layer like behaviour arising because of no interlayer interaction.
  • Electron diffraction – a technique to study the morphology of the given twisted system.



  • The new low-cost method of upscaling production of graphene while preserving its single layered properties may reduce the cost of producing this thinnest, strongest and most conductive material in the world.


What is Graphene?

  • Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice.
  • The 2010 Nobel Prize in Physics was awarded to Andre Geim and Konstantin Novoselov for their research on graphene.
  • Graphene is a transparent and flexible conductor that holds great promise for various material/device applications, including solar cells, light-emitting diodes (LED), touch panels, and smart windows or phones.
  • Smartphone products with graphene touch screens are already on the market.
  • Graphene is a boon for energy storage, coatings, sensors as well as superconductivity applications.
