Researchers have designed new liquid-coated air filters that allow for improved early detection and analysis of airborne bacteria and viruses, including the one that causes COVID-19. They developed a ...

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 ...

Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape ...

Filtering water is an incredibly important process, but it's not as simple as it seems. As the pores in a membrane inevitably get clogged with material, it takes time and energy to clean or replace ...

Researchers from the University of Maine and University of Massachusetts Amherst have designed new liquid-coated air filters that allow for improved early detection and analysis of airborne bacteria ...
