The filter material to analyze particulate matter with Raman or FTIR microspectroscopy plays a vital role. Their simple task is to filter liquids to isolate solids onto filters – but as soon as you ...

A new material made from several layers of graphene is an effective shield for terahertz and microwave radiation, while letting visible light through. So say researchers in the US, who have created ...

Scientists in Australia have developed new ultra-thin filters that can separate valuable chemicals from liquid mixtures fast ...

A new material can pull a toxic, hard-to-degrade industrial chemical from drinking water more effectively than current methods. Perfluorooctanoic acid, or PFOA, hangs around in the environment for ...

N95 masks look simple enough: two outer layers of fabric that form the shape of the mask, with a thin filter between. It's that sandwiched inner layer that complicates the mask's construction and ...

Researchers at the Department of Energy’s Oak Ridge National Laboratory are tackling a global water challenge with a unique material designed to target not one, but two toxic, heavy metal pollutants ...

When it comes to auto care, your car requires a lot of routine maintenance to stay in prime condition. Those tasks include things like fluid top-offs and replacements, belt changes, as well as wheel ...
