HAL partners with CeNS to promote science
In an attempt to popularise science and promote social outreach, Hindustan Aeronautics Limited (HAL) on Friday signed a Memorandum of Agreement with the Centre for Nano and Soft Matter Sciences (CeNS) for the establishment of a HAL Advanced Academic Initiation Centre, under its CSR initiatives. The HAL Advanced Academic Initiation Centre will be established at the CeNS' Arkavathi Campus in Karnataka. It will serve as a dedicated hub for science education under CeNS' flagship Vigyaani Vidyarthi Vichar Vinimay (V4) programme, which has already engaged over 20,000 students from 200 institutions and introduced them to the latest advancements in science and technology. 'The HAL Advanced Academic Initiation Centre will enable CeNS to reach out to a greater number of students and foster curiosity among young minds, especially those from rural areas who have limited exposure to advanced scientific concepts,' said D.K. Sunil, chairman and managing director, HAL.

CeNS scientists develop pocket-sized sensor to detect toxic sulfur dioxide
Scientists from the Centre for Nano and Soft Matter Sciences (CeNS) have developed a pocket-sized sensor that can help detect toxic Sulfur Dioxide (SO2), which is responsible for respiratory irritation, asthma attacks, and long-term lung damage, even at extremely low concentrations. According to the Department of Science and Technology, SO2 is a toxic air pollutant commonly released from vehicles and industrial emissions, and even minute exposure can cause serious health issues and long-term lung damage. It is said that SO2 is hard to detect before it has an adverse effect on health. 'Monitoring SO2 levels in real-time is crucial for public safety and environmental protection, yet existing technologies are often expensive, energy-intensive, or unable to detect the gas at trace levels,' it said. To overcome this, the CeNS scientists have fabricated a sensor by combining two metal oxides, Nickel Oxide (NiO) and Neodymium Nickelate (NdNiO3), through a simple synthesis process. 'While NiO acts as the receptor for the gas, NdNiO3 serves as the transducer that efficiently transmits the signal, enabling detection at concentrations as low as 320 parts per billion (ppb), far surpassing the sensitivity of many commercial sensors,' the department said. To demonstrate the capabilities of this material, the team led by S. Angappane developed a portable prototype that incorporates the sensor for real-time SO2 monitoring. The prototype features a straightforward threshold-based alert system that activates visual indicators, green for safe, yellow for warning, and red for danger, allowing easy interpretation and response, even by users without scientific expertise. Its compact and lightweight design makes it suitable for use in industrial areas, urban locations, and enclosed spaces where continuous air quality monitoring is necessary. 'With its high sensitivity, portability, and user-friendly operation, this sensor system offers a practical solution to monitor and manage SO2 pollution, supporting public health and environmental safety. This work demonstrates the potential of material science to create accessible technologies for real-world challenges,' the department added.

Indian Scientists Unlock Secret To Clean Fuel Using Only Sunlight. Here's How
In a significant breakthrough, scientists at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have developed a revolutionary device that harnesses solar energy to produce green hydrogen. This innovative technology has the potential to power homes, vehicles, and industries while reducing reliance on fossil fuels. The Science Behind the Breakthrough Led by Dr Ashutosh K Singh, the research team designed a state-of-the-art silicon-based photoanode using an n-i-p heterojunction architecture. This device splits water molecules into hydrogen and oxygen using only solar energy and earth-abundant materials. The materials were deposited using magnetron sputtering, a scalable and industry-ready technique that ensures precision and efficiency. This thoughtful engineering approach allowed better light absorption, faster charge transport, and reduced recombination loss, key ingredients for efficient solar-to-hydrogen conversion. Key Features of the Device High Efficiency: Achieved an excellent surface photovoltage of 600 mV and a low onset potential of around 0.11 VRHE. Long-Term Stability: Operated continuously for over 10 hours in alkaline conditions with only a 4% performance drop. Scalability: Demonstrated successful performance at a large scale with a 25 square centimetre photoanode delivering excellent solar water-splitting results. Implications and Future Prospects This breakthrough aligns with India's National Green Hydrogen Mission, aiming for carbon neutrality and energy independence. The technology could fuel hydrogen-based energy systems, powering everything from homes to heavy industries sustainably. "By selecting smart materials and combining them into a heterostructure, we have created a device that not only boosts performance but can also be produced on a large scale," said Dr Singh. "This brings us one step closer to affordable, large-scale solar-to-hydrogen energy systems." The work has been published in Journal of Materials Chemistry A, published by the Royal Society of Chemistry, and the researchers believe this is just the beginning. With further development, the technology could fuel hydrogen-based energy systems, from homes to factories, all powered by the sun.

India's rare-earth doping breakthrough hints at future of energy storage
New Delhi: Indian scientists have engineered a new energy storage material that demonstrated 118 per cent energy retention and 100 per cent coulombic efficiency , marking a major development in supercapacitor performance. The breakthrough has been achieved by researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, in collaboration with Aligarh Muslim University. The research team, led by Dr Kavita Pandey at CeNS — an autonomous institute under the Department of Science and Technology — used silver niobate (AgNbO₃), a lead-free material, as the base and introduced lanthanum doping to improve performance. According to the findings, the addition of lanthanum, a rare-earth element, improved the electronic conductivity of the material and reduced particle size, increasing surface area available for energy storage. The doped material retained 118 per cent of its initial capacity after repeated use and achieved 100 per cent coulombic efficiency, with no loss of energy during charge-discharge cycles. A prototype asymmetric supercapacitor developed using the new material was able to power an LCD display. The research has been published in the Journal of Alloys and Compounds. 'This research demonstrates the potential of lanthanum doping as a method to tailor silver niobate for high-performance supercapacitors,' the research paper stated. The study highlights the role of rare-earth doping in improving the properties of silver niobate nanoparticles for electrochemical energy storage. The team said future research would explore doping strategies in other perovskite materials and focus on scaling up lanthanum-doped silver niobate for commercial use.
