Acetogenic bacteria, known for turning carbon dioxide and hydrogen into acetate, have a unique way of gobbling up hydrogen. Scientists studied three types of these bacteria to see how fast they can consume hydrogen at different levels. Surprisingly, all three types followed a simple rule: the more h
Three-dimensional printing has revolutionized the way we think about creating tissue replacements. What makes this technique so versatile is the ink used to print the tissues. Ideally, this ink should be safe to use in the body, stable, and capable of maintaining its shape, size, and function after
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
Imagine trying to grow plants in a freezing environment. Sounds tough, right? Cold stress makes it super hard for plants to grow, produce food, and even survive. But what if there was a secret weapon that could help plants rough it out? Enter hydrogen sulfide (H₂S), a gas that's found almost everywh
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
Hydrogen evolution reaction (HER) is vital for generating hydrogen fuel through water splitting. To make this process sustainable, researchers are searching for abundant materials like silicates. A recent study synthesized various metal metasilicates using a simple wet-chemical method followed by hi
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
We all know that lead-based metal halide perovskites are great at converting light into electricity. But they're also toxic, which holds them back from wider use. What if there's a safer alternative? Scientists have been exploring a series of perovskite microcrystals called CsCuClxBr3-x. This time,
Have you ever wondered how to make composting more efficient? A recent study found that combining special bacteria with iron can speed up the breakdown of plastics and keep more nitrogen in the soil. These scientists used a mix of biochar (which is like charcoal made from plants) and specific bacter
