India’s AMCA Programme Takes Flight: A Stealth Leap into the Future of Air Combat

By
In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative.

Graphene: The Wonder Material with Quantum Potential

Recent Discovery

  • Researchers have discovered a new quantum state in twisted bilayer-trilayer graphene.
  • Electrons in this state form a lattice but still allow resistance-free edge currents, making it valuable for quantum computing.
  • This discovery enhances stability against noise, a major challenge in quantum computing.

What is Graphene?

  • Graphene is a single layer of carbon atoms arranged in a hexagonal honeycomb lattice.
  • It is an allotrope of carbon, like graphite and diamond.

Key Properties of Graphene

  1. Thinnest & Lightest Material
    • Only one atom thick.
    • 1,000 times lighter than paper.
  2. Strongest Known Material
    • 200 times stronger than steel.
  3. High Conductivity
    • Conducts electricity better than copper.
    • High thermal conductivity.
  4. Highly Transparent
    • 98% transparent to light.
  5. Flexible and Stretchable
    • Can be used in bendable electronics.
  6. Chemically Stable & Impermeable
    • Does not react easily and prevents gas or liquid penetration.

Applications of Graphene

  • Quantum Computing: New quantum states improve computational stability.
  • Flexible Electronics: Used in bendable displays and wearable devices.
  • Supercapacitors & Batteries: Enhances energy storage efficiency.
  • Biomedical Applications: Used in drug delivery and biosensors.
  • Water Purification: Graphene-based membranes for desalination.
  • Aerospace & Defense: Lightweight yet strong material for space tech.

Future Potential

  • Graphene’s unique electronic and quantum properties could revolutionize:
    • Ultra-fast computing
    • Transparent solar panels
    • Next-gen AI chips

This recent discovery in bilayer-trilayer graphene further strengthens its role in next-generation quantum devices.

Manasvi: IIT Delhi’s Bold Step Toward Empowering High School Girls in STEM

By
In a world increasingly shaped by technological advancement, ensuring gender equality in STEM (Science, Technology, Engineering, and Mathematics) is no longer a choice—it’s a necessity. Recognizing this, the Indian Institute of Technology (IIT) Delhi launched a pioneering initiative titled ‘Manasvi’ , a STEM mentorship programme for high school girls . The programme, unveiled in New Delhi today, is spearheaded by the institute’s Academic Outreach and New Initiatives Office . Manasvi is not merely an educational engagement; it is a transformative platform aimed at inspiring and empowering young girls to pursue careers in STEM, fields traditionally dominated by men. At the heart of Manasvi lies the ambition to address the deep-rooted gender disparity in STEM education and careers . Despite producing the largest number of science graduates globally, India continues to see disproportionately low female representation in STEM careers —a statistic that underscores the urgent need for su...
