The world of water electrolysis is always looking for better catalysts. These tiny helpers speed up the process of splitting water into oxygen and hydrogen. One such process is called the oxygen evolution reaction. It's a big deal in proton exchange membrane water electrolysis. This is where a new kind of catalyst comes in. It's made of ruthenium dioxide, but with a ...
The world of organic chemistry is buzzing with excitement over a new type of catalyst. This catalyst uses visible light to drive chemical reactions. Most of the focus has been on oxygen and nitrogen-based catalysts, like acridinium and pyrylium salts. However, sulfur-based catalysts have been largely overlooked until now. A new sulfur-containing catalyst has eme...
Olive oil is famous for its health benefits. Two key compounds in olive oil are oleacein and oleocanthal. They are known for fighting inflammation, cancer, and even brain diseases. But there is a catch. These compounds are highly reactive. They quickly bond with primary amines. These amines are found in lab settings and in the human body. This makes it hard for scien...
Water is a superstar in the world of chemistry. It's everywhere, and it's great at breaking down molecules in a process called hydrolysis. This happens all the time in nature and in labs. But predicting how water will react with different substances is tricky. Small changes in a molecule can make a big difference. Plus, the acidity or basicity of the water can change...
Blood clots can be tricky to understand. They play a crucial role in stopping bleeding, but they can also cause problems if they form in the wrong place. One key factor in how clots behave is their permeability, or how easily blood can flow through them. This is important because it affects how platelets, tiny blood cells that help with clotting, move and stick to th...
In the dead of winter, Beijing's air quality often takes a nosedive. The city's notorious smog is a complex mix of pollutants. One key player in this mix is sulfur-containing aerosols. These tiny particles come from the chemical reactions happening in the air. But how do they form? Let's dive into the science behind it. Fossil fuels are a big part of the problem. Wh...
Chemists have found a clever way to turn certain compounds into useful chemicals. They use a special substance called PPh3 and light to make this happen. This process is gentle and works with many different types of chemicals. It's like having a magic wand that can change one thing into another without causing any harm. First, let's talk about the magic wand, PPh3. ...
Imagine a world where your clothes can monitor your health and movements without needing a power source. Sounds like science fiction, right? Well, scientists have taken a big step towards making this a reality. They've created a new type of flexible pressure sensor that doesn't need external power. This sensor is made using a process called electrospinning and electr...
Imagine peeking into the world of tiny molecules to figure out their structures. This is exactly what some clever chemists have done. They found a new and exciting way to make stable compounds called osmate esters. And why are these esters important? Well, they make it easier to figure out the shape and positioning of molecules using a technique called X-ray analysis...
Photochemical reactions are like mysterious puzzles in the world of chemistry. Unlike regular chemical reactions, where understanding the energy surface is key, photochemical reactions involve light absorption, leading to a nonstationary state in molecules. This state allows for internal conversions, where electrons and nuclei interact, a process ignored by the Born-...
