Swiss postage stamps from 1850 to 1908 weren’t just about postage. They were tiny canvases showing off the best pigments and dyes of the time. For the first time, researchers closely examined 98 of these stamps using advanced tools like Raman spectroscopy and scanning electron microscopy. Instead of
Dow, a major player in material science, has seen its stock climb despite a struggling wider market. The company stands out with a diverse product range and factories spread across the globe. Recently, its stock hit a fresh yearly peak of $42. 68, and it pays a steady dividend of 3. 32%. But experts
In the world of technology, there's a big push to make devices that can handle light in smart ways. One such device is a photodetector, which turns light into electrical signals. Recently, scientists made a big leap forward with a new type of photodetector. This isn't just any photodetector—it's sel
Borophene, a single layer of boron atoms, is a standout in the world of two-dimensional materials. Its unique structure gives it special properties, like high electron mobility and flexibility. But it's not all smooth sailing. Making borophene without flaws is tough, and it doesn't like being expose
Ever wondered how to make things slide smoothly and quietly? Scientists have been working on this problem for a while. They wanted to create materials that can handle water well and reduce friction and noise. This is important for things like machinery parts that need to move smoothly without making
In the world of materials science, tiny changes can lead to big surprises. Take EuVO2H films, for example. These films are special because they can handle a mix of europium ions (Eu2+ and Eu3+) without falling apart. Normally, when europium changes its valence, it causes big problems. The ions are d
Lithium-sulfur batteries are seen as a big deal for the future of energy storage. They can hold a lot of energy and are lightweight. But there are some big problems holding them back. One issue is the shuttle effect, where tiny particles move around and cause damage. Another problem is the growth of
Piezoelectric materials are special because they can turn mechanical energy into electrical energy and vice versa. Now, scientists are making these materials clear, like glass, which opens up new possibilities. These clear materials can be used in things like medical devices, acoustic systems, and e
Lithium-sulfur batteries hold great promise, but they have a big problem. The shuttle effect and slow sulfur conversion cause them to wear out quickly. To tackle this, scientists created a smart sulfur host called VGS@MoC/NCNF. This host is made of nitrogen-doped carbon nanofibers coated with graphe
Researchers have found a way to make rechargeable zinc-air batteries last longer and work better. They did this by mixing a special catalyst with a smart helper called CeO2. The catalyst, made of iron and cobalt atoms, is good at helping oxygen reactions. But it has problems. It wears out too fast a
