Rahul Deb, Debajyoti Bhattacharjee, and Syed Arshad Hussain, all from Tripura University, investigate the use of bio-organic materials to create these innovative memory devices. Their work explores how naturally derived substances can achieve reliable resistive switching, a process where a material's electrical resistance changes in response to a stimulus, enabling data storage. This research significantly advances the field by demonstrating the viability of sustainable, biocompatible materials for next-generation memory applications and opens new avenues for developing environmentally friendly and high-performance electronic devices. Simple device structures, low power requirements, rapid switching…...

6+ hour, 25+ min ago (667+ words) A new study has found that many everyday chemicals can harm the good bacteria living in your gut. These bacteria are important for keeping your body healthy, but researchers have discovered that 168 different human-made substances can stop these microbes from growing properly. Many of these chemicals are found in food, drinking water, and the environment, but until now, they were not believed to affect gut bacteria. The study was done by scientists at the University of Cambridge. They tested over 1,000 different chemicals to see how they affected 22 common types of gut bacteria in a lab setting. These chemicals included pesticides like herbicides and insecticides used on crops, and industrial chemicals found in plastics and flame retardants. Our gut is home to thousands of different kinds of bacteria that help with digestion, the immune system, mental health, and more. If something…...

6+ hour, 27+ min ago (428+ words) A rocky exoplanet outside the Earth's solar system may have an atmosphere, according to new evidence gathered by NASA researchers. The exoplanet's low density has surprised and baffled scientists, NASA said. It may have an unusual composition from planets in Earth's solar system. It could also be surrounded by a thick atmosphere, which would not be expected on an exoplanet with these features. But the James Webb Space Telescope helped scientists gather data that showed that unlikely scenario might be the case. Researchers used the telescope's Near-Infrared Spectrograph to measure the exoplanet's dayside temperature. If the exoplanet has no atmosphere, scientists estimated its dayside temperature would be about 4,900 degrees Fahrenheit. But the spectrograph found TOI-561b's temperature closer to 3,200 degrees Fahrenheit, far cooler than expected. Just determining the temperature of the exoplanet doesn't confirm if there is an atmosphere there,…...

7+ hour, 3+ min ago (185+ words) Dr. Yu Lei, chair of the UAH Department of Chemical & Materials Engineering. "PFAS are often called forever chemicals because their carbon'fluorine bonds are among the strongest in chemistry, making them very hard to break down," the researcher notes. "They can move from one place to another, for example, from water into soil or sludge, instead of being truly destroyed. That persistence makes them difficult to manage. The work entails a combination of both laboratory research and computational modeling with seven universities collaborating closely across their respective areas of expertise. "Beyond the research, the project also emphasizes workforce development ' training graduate students, postdocs and junior faculty through collaborative research and exchanges across the three states. It's not just about addressing the PFAS challenge, but also about building the next generation of scientists and engineers ready to take on future environmental problems....

7+ hour, 39+ min ago (658+ words) Doping the cathode material with high-valent tantalum and adding 0.5 mole percent of tantalum oxide (Ta'O) reduced the rate of battery capacity decay per cycle by nearly half. Researchers in Russia have improved the cathode material, which helped them improve battery lifespan. Skoltech researchers proposed doping the cathode material with high-valent tantalum and discovered that adding 0.5 mole percent of tantalum oxide (Ta'O) reduced the rate of battery capacity decay per cycle by nearly half. The work paves the way for creating more durable, safe, and powerful lithium-ion batteries for electric vehicles, electronic devices, and energy storage systems.The research team revealed that modern lithium-ion batteries use layered nickel-rich oxide cathodes to store more energy. However, the higher the nickel content, the faster the battery degrades. Repeated charging and discharging causes cracks to slowly form in the material particles, leading to capacity…...

8+ hour, 17+ min ago (532+ words) By removing electricity from the equation, researchers found lithium behaves very differently inside charged membranes. A simple laboratory experiment at the University of Michigan has revealed an unexpected way to extract lithium from brines long dismissed as uneconomical. The discovery could unlock vast lithium resources trapped in magnesium-rich waters, offering a more sustainable route to meet rising demand from batteries, electric vehicles, and renewable energy systems. Lithium supply already faces mounting pressure. Mining from hard rock remains costly and environmentally damaging, while conventional brine extraction depends on vast evaporation ponds that consume land and water. Although brines hold more than half of the world's lithium, most remain unused because high magnesium levels complicate extraction. "In some natural brines, the conventional approach isn't economical, so people aren't utilizing the resource," said Jovan Kamcev, an associate professor of chemical engineering and the…...

10+ hour, 28+ min ago (435+ words) Toxic PFAS "forever chemicals" are found in'nearly half of all U.S. drinking water. These harmful chemicals are linked to cancer, developmental issues, and immune system damage. They enter our water systems through industrial discharges, firefighting foams, and landfill runoff. Once present, they are nearly impossible to remove using traditional methods. For years, families, utilities, and local governments have faced a difficult choice: accept unsafe water or pay for costly, slow, and incomplete cleanup methods. After 10 years of research and development, Eco World Water'has the solution. At Eco World Water, we have completed four months of rigorous pilot testing with an independent laboratory, under protocols reviewed by the Florida Department of Environmental Protection. The verified lab results confirm that our system can reduce PFAS to non-detectable levels in a safe, reliable, and quick manner. More importantly, the system produces clean, safe water…...

12+ hour, 27+ min ago (908+ words) Home " Research " Materials We really need to do something about our cement. We live in the Age of Concrete. Look around you. If you're inside, the building likely has a lot of concrete. If you're outside, you're standing on concrete. It's the skeleton of our modern world, the ubiquitous grey material that builds our cities. It's reliable, it's cheap, and it's slowly cooking up the planet. Concrete alone is responsible for around 8% of our global emissions. If it were a country, it would rank third in the global emissions table, right behind China and the US. But we've accepted this as a dark pact necessary for civilization. Nima Rahbar and his team at Worcester Polytechnic Institute (WPI) believe we can do better. They've developed a new material that is cheap, strong, and actually carbon negative. It's remarkable that we've become…...
