Shiv Nadar University researchers develop rare-earth-free composite material for multifunctional applications

By A Representative

Researchers at Shiv Nadar University, Delhi-NCR, have announced the development of a rare-earth-free composite material, ZnO@β-SiC, with applications in energy-efficient lighting, artificial intelligence, and environmental solutions. This groundbreaking innovation marks a significant advancement in materials science.

Led by Professor Aloke Kanjilal and research scholar Mr. Bisweswar Santra, the research addresses global challenges by providing a sustainable, scalable alternative to rare-earth elements. The composite demonstrates exceptional optical, neuromorphic, and photocatalytic properties, making it suitable for solid-state lighting, memory storage systems, AI technologies, and water purification.

One of the highlights of this material is its dual-band photoluminescence spanning visible to near-infrared regions, developed through optimized annealing conditions. It reduces dependence on scarce rare-earth materials and supports India's self-reliance in lighting technologies.

The researchers demonstrated the composite’s forming-free resistive switching devices with ultra-low power consumption (~100 μW) and rapid response times (40 ns), as well as its ability to retain data for extended periods. Its neuromorphic properties open pathways for energy-efficient AI applications, including robotics and intelligent systems.

Additionally, the composite exhibits outstanding photocatalytic properties, efficiently degrading organic pollutants like methylene blue under UV radiation within 25 minutes, offering scalable solutions for wastewater treatment. Its radiation hardness ensures stability under extreme conditions, including space and nuclear environments.

Prof. Kanjilal emphasized the transformative impact of the material, stating, “This innovation not only improves existing technologies but creates new possibilities by integrating sustainability and performance.”

This research underscores Shiv Nadar University’s commitment to interdisciplinary advancements that address real-world challenges.

A fearless spirit lost: Rebecca Thomson dies at 17-hour Catalina Swim Mark

By Harsh Thakor On July 26, 2026, Rebecca “Becky” Thomson suffered cardiac arrest while attempting the Catalina Channel Swim — a marathon open water crossing from Catalina Island to the California mainland. After swimming for 17 hours, Thomson collapsed in the water. Despite the painstaking efforts of emergency responders and the medical staff at Harbor-UCLA Medical Center, she succumbed to a devastating hypoxic brain injury and died Friday evening.

Hyderabad-based Urdu university "bars" entry of its new chancellor, who had "initiated" reforms in institute

Counterview Desk In an unusual controversy, Aslam Parvaiz, vice-chancellor of of the Hyderabad-based Maulana Azad National Urdu University (MANUU) has restricted the entry of its newly appointed Chancellor, Firoz Bakht Ahmed, allegedly because he was trying to initiate reforms, including setting up of a Maulana Azad Center for Composite Culture and Progressive Studies, Model Madrasa, Center for Empowerment of Muslim Women, Course for the Development of Legal Vocabulary and Legal Consciousness in Urdu, and so on.

Defying anti-insurgency campaign, Maoists hold demonstrate in West Bengal and Punjab

By Harsh Thakor* In a notable development, despite the Government of India's sustained campaign against the Maoist insurgency in recent years, organisations in West Bengal and Punjab have continued to hold public programmes associated with the movement's political legacy. Recently, groups in Kolkata and Moga organised separate events focusing on the legacy of the Maoist movement, contemporary political developments, and issues relating to education, democratic rights and social movements.
