Scientists have cooked up a clever way to turn CO2 into useful stuff without needing fancy equipment or lots of energy. They made a special material called a covalent organic framework (COF) that acts like a tiny, super-strong net. This net traps tiny bits of palladium, a special metal, to create a powerful catalyst. The catalyst is super good at turning CO2 into ot...
Enzymes are like tiny workers in our body, speeding up chemical reactions. But they can get tired or damaged easily. Scientists found a way to protect them using something called covalent organic frameworks (COFs). Think of COFs as tiny, strong boxes that can hold enzymes safely inside. The team used a simple, one-step method in water to put enzymes inside these COF...
Ion separation is a big deal in many fields. It's like sorting out different types of ions in a crowded room. But it's tricky. Most membranes struggle with this task, especially when there are mixed ions around. They just can't pick and choose effectively. Now, there's a new approach using something called covalent organic frameworks, or COFs. These are like tiny, s...
Lithium metal batteries are back in the spotlight. To make them work better, researchers are focusing on improving the electrolytes. These electrolytes need to move ions around efficiently and manage the surfaces where different parts of the battery meet. One exciting approach involves creating special materials called 3D covalent organic frameworks (COFs). These...
The quest for efficient hydrogen storage has led scientists to explore various materials. One such material is covalent organic frameworks (COFs). These structures are known for their large surface areas and adjustable pores. However, their interaction with hydrogen is often too weak. This is a problem because weak interaction means hydrogen doesn't stick around long...
Cobalt is a key player in a new method that turns CO2 into useful stuff. This isn't just any method. It uses sunlight to power the reaction. The process involves special materials called metal-covalent organic frameworks (MCOFs). These MCOFs have tiny, super-efficient parts called catalytic active sites (CASs). These CASs are where the magic happens. The more of thes...
Covalent-organic frameworks, or COFs, are like the superheroes of the materials world. These materials are designed with specific molecular structures to perform amazing tasks, like detecting tiny amounts of ammonia (NH3) at room temperature. Imagine two COFs, β-keto-AnCOF and imine-AnCOF, which have the same building blocks but different connections. Both are porous...
Ever wonder how our bodies signal trouble? Turns out, tiny molecules called malondialdehyde, or MDA, get involved. When our bodies face oxidative stress, they produce more of these molecules. Think of MDA as red flags for possible health issues. Scientists have been on the hunt for a better way to detect these red flags. They've come up with a smart sensor using...
Like a factory with two functions, some metal-organic cages (MOCs) can either store the pollutant SO2 or turn it into a less harmful form. The key? Different chemical companions, known as counterions. By swapping these companions, scientists can flip the switch between just trapping SO2 or converting it into sulfate. Take Pd6L8 MOCs for instance, which can hold up to...
