Scientists concoct new coating to protect gun barrels from wear

In a recent study, researchers from the Indian Institute of Technology Kanpur have explored the use of a new blend of chromium (III) as an eco-friendly electrolyte for depositing chromium-based coatings on metallic barrels. They reinforced chromium with carbon nanotubes (CNTs) and a ceramic compound called yttria stabilised zirconia (YSZ), to improve the properties of the coat.

Imagine just switching on your lights and downloading a movie in a second. The world demands high-speed internet connectivity at a lower price. This increasing clamour for speed and bandwidth is opening up new avenues, and one such evolving domain is LiFi - a wireless technology that makes use of light-emitting diodes (LEDs) to transmit data. Light waves are 10,000 times denser than WiFi signals, so there is vast untapped potential here.

India's new heat wave prediction system could be our first line of defence against the scorching heat

A recent assessment by the World Meteorological Organisation has declared heat waves as the deadliest extreme weather event in the years 2015–2019, causing more than 8,900 deaths globally. In May 2015, temperatures crossed 45°C in Odisha and Telangana in the fifth deadliest heat wave in history, with a death toll of 2,300. With 30% of the global population living in regions susceptible to 20 heat wave days in a year and the rising global temperatures, one can conclude that its toll will only increase in the years to come. In such situations, warnings about impending heat waves can be lifesavers. However, very few studies have focused on such a prediction system to date, with none looking at real-time predictions. Now, researchers have developed a prediction system to predict heat waves a couple of weeks in advance. The study, funded by the Ministry of Earth Sciences, Govt. of India, was published in the journal Scientific Reports.

New insight into genetic mutation may revolutionise bladder cancer treatment

Among the various types of cancer, Urothelial Bladder Cancer (UBC) is responsible for around 2 lakh deaths per year around the world. This cancer affects the inner lining of the bladder and is the most common form of bladder cancer. It usually affects aged individuals, with blood in urine and painful urination as the first sign of its manifestation. Conventional methods of treatment involve surgical removal of cancerous tissue in the bladder and chemotherapy.

New Possibilities for Nano-sized Optical Filters

Prof Bhaskaran Muralidharan and Dr Alestin Mawrie of the Indian Institute of Technology Bombay have researched a specific category of two-dimensional nanomaterials, called semi-Dirac materials. Their theoretical studies show that it is possible to engineer semi-Dirac materials to make optical filters and efficient thermoelectric nanodevices.

New Way to Determine Arrow of Time

One of the annoying side effects of being absorbed in a gripping novel is that the cup of tea on the table becomes cold! Unfortunately, the tea would not heat itself by absorbing the heat around it, just as pieces of a broken egg would not put themselves together or milk mixed in coffee would not separate by itself. Such things are irreversible, and define a fixed direction of time—that from the past towards the future. This apparent progression of time is called the ‘arrow of time’. In a recent study, Prof Mahendra Verma of the Indian Institute of Technology Kanpur, suggests a way, different from any previous ones,  to determine the direction in which time is progressing. He uses the concept of energy cascade to define the arrow of time.

Indian research barely covered on social media, finds study

In a recent study, published in the journal Current Science, researchers from Banaras Hindu University (BHU), Varanasi, South Asian University, New Delhi, and Leibniz Institute for the Social Sciences, Germany, have studied how much attention Indian research gets on social media.

Fighting floods the 'expert' way

 During the fag end of 2015, Chennai experienced severe floods resulting in the death of about 500 people and economic losses of about INR 50,000 crores. The flooding stranded the city and was termed a 'man-made disaster' resulting from irresponsible water management and rapid urbanisation. The northeast monsoon of the year left most parts of South India marooned, exposing how vulnerable our cities are to such catastrophes. That's when the Office of the Principal Scientific Advisor took a major initiative to develop a real-time, integrated, urban flood forecasting system that was non-existent in our country. Soon after, a team of scientists from various institutes across the country, swung into action to develop the first-ever expert system in India to forecast floods. In a recent study, published in the journal Current Science, the researchers shed light on the development of the automated flood forecasting expert system.
