Imagine powering your car or home with nothing but water and air. That's the promise of proton exchange membrane fuel cells (PEMFCs). But to make this a reality, scientists need to find a way to make a crucial process called oxygen reduction reaction (ORR) happen more efficiently in acidic environme
You might have heard that vitamin D is good for your bones. But did you know it might also help people with inflammatory bowel disease (IBD)? IBD is a group of long-term conditions that cause inflammation in the gut. Some studies have shown that taking vitamin D supplements can help IBD patients, bu
Scientists have long known that nickel-iron catalysts are great at producing oxygen from water, especially in alkaline conditions. But how they do it so well was a mystery—until now. A recent study looked at a special catalyst, nickel-iron phosphide (NiFeP), which is super active and stable. It only
Scientists are always on the hunt for better ways to split water into hydrogen and oxygen. This time, they've designed special Ru-B-Cr parts within RuO₂ nanofibers to make the Ru sites more active. This overcomes the hurdles of RuO₂ catalysts, which usually aren't very good at producing hydrogen and
Did you know that ruthenium dioxide (RuO2) is a star player in generating oxygen from water, also known as the oxygen evolution reaction (OER)? Well, it's not always perfect. Scientists found that adding a bit of manganese (Mn) to RuO2 can make it work better and last longer. When they tested this M
Scientists have uncovered new data from the Upper Doushantuo Formation in South China that sheds light on a significant event known as the Shuram Excursion. This event, marked by a steep drop in carbon isotopes, is one of the largest in geological history. But until now, its exact age has been a mys
Scientists have been exploring how oxygen affects the burning of coal. They conducted experiments by changing the amount of oxygen and heat. They examined the oxidized parts of the coal to see how easily they could be ignited. By increasing the coal from 5 to 300 grams, they found that the needed te
In the world of electronics, heat management is crucial. Polymer composites, especially those with boron nitride (BN), are widely used for this purpose. However, their effectiveness depends on how well the fillers are arranged and how they interact with the surrounding material. This study dives int
Bone tissue engineering faces challenges that require advanced materials. One strategy is to create composite scaffolds. These scaffolds need to support bone repair and have enough strength. Researchers tried making a scaffold from bacteria, mineral, and graphene. Each part is sourced from waste, li
You’ve probably heard that microplastics (MPs) are bad for the environment, but did you know they also help antibiotics move around in groundwater? This happens because MPs can carry antibiotics like oxytetracycline (OTC) as they journey through soil and surface water. According to research, this me
