Scientists have known for years that membranes can do things such as act as a filter for saltwater. When salty ocean water is moved through a membrane, clean water comes out the other side that can be ...

Throughout her career, Ayse Asatekin, associate professor of chemical and biological engineering at Tufts University, has sought to use filters to prevent illness and protect the environment. One ...

Researchers at Monash University have developed a new filter designed to address the limitations of conventional water filters, which are often ineffective at removing smaller PFAS molecules. Image ...

Researchers developed a new membrane that selectively filters out lithium from brines, offering a faster, cleaner way to produce the element at the heart of nearly every rechargeable battery. The ...

Traditional water filters struggle to remove smaller PFAS molecules, but a new Monash-designed filter changes that. Researchers at Monash University have developed a water filtration membrane that ...

Most people on Earth get fresh water from lakes and rivers. But these account for only 0.007 percent of the world’s water. As the human population has grown, so has the demand for fresh water. Now, ...

A "straight out of science fiction" liquid membrane developed by a team of Penn State mechanical engineers acts as a "reverse filter" that lets large objects through while blocking small ones. The ...

To build a single filter that could both capture metals and remove salt, my colleagues and I first needed a material that could remove many different contaminants — mostly heavy metals — from water.
