Fuel cells are like the heart of clean energy. They convert hydrogen into electricity. But there's a catch. The process isn't as smooth as it could be. Especially in alkaline environments. The hydrogen oxidation reaction (HOR) is often slow and easily disrupted by carbon monoxide (CO). This is a big problem for anion exchange membrane fuel cells (AEMFCs). Scientists...
Researchers recently responded to feedback about their study on formamidinium tin iodide nanocrystals. The original work aimed to reduce impurities in these tiny particles, specifically focusing on tin(IV) impurities. The feedback came from A. Dhingra, who raised some points about the research. The study is important because it deals with materials that could be use...
Perovskite nanocrystals are tiny particles that have amazing light-managing abilities. These particles, specifically CsPbX3, are crucial for advanced optoelectronic devices. Among them, cyan-emitting perovskites show great promise for high-quality lighting. It is important to note that light can significantly alter the optical properties of these materials during po...
Scientists have found a clever way to improve the light-emitting properties of tiny crystals called Cs₂NaBiCl₆. They added a bit of indium to the mix and discovered that the crystals shone brighter and more steadily. These crystals are special because they don't contain any lead, making them safer for the environment. The researchers started by creating the crystals...
Have you ever wondered why blue light-emitting perovskite materials aren't as efficient as they could be? The problem lies in intrinsic defects that trap charge carriers. Scientists have found a clever solution: wrap CsPb(Cl/Br)3 nanocrystals in silica. This combination, known as CsPb(Cl/Br)3 NCs@SiO2, shows higher photoluminescence intensity and lifetime compared to...
You know how tiny nanocrystals are super important for light-driven reactions? Well, scientists are looking at CsPbBr3 nanocrystals, or CPB NCs, because they're fantastic at absorbing light. But they've got a downside: they struggle with charge recombination, which affects their ability to catalyze reactions efficiently. To fix this, researchers paired CPB with ferro...
Have you heard about mixing stuff really quickly to make cool things happen? Scientists are doing just that with sound waves. They've found a clever trick to speed up the growth of tiny particles called nanocrystals. These tiny crystals are part of a group called lead halide perovskites, and they're great for working with light. The secret lies in a special mixer th...
