Metals face a big problem: rust. It's a natural process, but it can be a real pain. Scientists have been working on ways to slow it down. One promising idea is using tiny containers to hold special chemicals that fight rust. But making these containers strong, long-lasting, and effective is tough. Recently, researchers created something special. They made a porous, ...
Sodium-ion batteries (SIBs) are stepping up as strong contenders in the world of energy storage. They are seen as a promising alternative to lithium-ion batteries, especially for large-scale applications. However, making SIBs that can handle different temperatures, deliver high performance, and last a long time is still a big challenge. Scientists have recently deve...
There's a big problem with certain chemicals. Nitroaromatic compounds (NACs) and radioactive iodine can hurt people and the environment. Scientists are working hard to find ways to detect and clean up these harmful substances. They've created two special materials called HTAEA and HTMB. These are like super sponges that can sense and soak up dangerous chemicals. Ima...
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...
A team of researchers recently developed a unique material that can split water into hydrogen and hydrogen peroxide using just visible light. This isn't just any material, though. It's a special kind of framework made from organic molecules. This framework has a clever design that helps it do its job better. It has three different building blocks and two types of...
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...
