Microsoft launches India’s first Cybersecurity Engagement Center in Delhi

Technology giant Microsoft has launched its first full-scale Cybersecurity Engagement Center (CSEC) in Delhi.

It is first-of-its-kind Cybersecurity Centre in India and overall 7th in the world including in Tokyo, Seoul, Beijing, Singapore, Berlin and Washington DC.

Key Facts

  • The CSEC will bring together Microsoft capabilities to foster deeper Cybersecurity collaborations with public and private sector organisations.
  • The centre will also build a trusted and secure computing environment, a critical enabler for India’s digital transformation.
  • The CESC will offer their expertise and work with partners to detect and take evasive measures to tackle cyber threats in India.
  • The centre is a part of Microsoft Consultancy Services (MCS), a dedicated response team based in India that will offer security consultancy services to business organisations.
  • It will offer services such as cyber monitoring, threat detection using machine learning based technology and take evasive measures to combat cyber threat.

IISER researchers use human hair to produce cheaper cathodes for solar cells

Researchers from Kolkata based Indian Institute of Science Education and Research (IISER) have produced cost-effective, metal-free cathodes using human hair for use in solar cells.

Significance: This is the first instance where a bio-waste-derived electrode (in this case human hair) has been used as cathode in a quantum dot sensitised solar cell device.

Key Facts

  • IISER researchers have developed graphitic porous carbon cathode by cleaning and drying human hair and treating with sulphuric acid to achieve precarbonisation.
  • It was then heated at different temperatures in the presence of inert gas for six hours to carbonise and bring better electrical conductivity for efficient charge transfer.
  • This efficient green cathode achieves highly catalytic graphitic porous carbon stage at optimum temperature of 850 degrees C.

Advantages

  • Producing graphitic porous carbon cathode using human hair is simple, quick and inexpensive. It has potential to bring down the cost of solar cells.
  • The bio-waste-derived cathode has higher efficiency to convert visible sunlight to electricity. It also enhances the power conversion efficiencies.
  • It generates high open-circuit voltage compared to conventional platinum and activated carbon cathodes.
  • It is metal-free cathode, while commonly used cathode is made of platinum metal and metal sulfides.
