Have you ever paused for a moment and thought about the marvel of technology, the humble kitchen sponge? can carry. It all would have been pretty miraculous if it hadn’t been so familiar.

But I have a slightly different question here. Can you make a liquid sponge? It’s kind of like the household variety, but instead of liquid you can suck in gas and pump it far. That makes it incredibly convenient. I guess. After all, we are in the midst of a climate emergency caused by emissions of greenhouse gases such as carbon dioxide and methane. Liquid sponges can provide a better way to soak up these gases and prevent harm.

The concept of spongy liquids may seem intimidating to the novice. As most of us learned in school, liquids are meant to fill the bottom of the vessel into which they are poured, and no holes or spaces are allowed. We have created and tested a wide variety of liquid sponges designed for We’re trying to find out just how useful this exotic technology is in practice.

What is a porous liquid

The history of liquid sponges (also called porous liquids) began in 2007 when chemist Stuart James began working at Queen’s University Belfast, UK. He was working on solids known as metal-organic frameworks (MOFs), cage-like compounds made of metal ions and carbon-based molecules. something special about
