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 ...

Unraveling the chemical processes in soot particle filters reveals new ways to produce synthetic fuels. Carbon particles are present in many aspects of our daily lives. Soot, which consists of tiny ...

Carbon particles are present in many aspects of our daily lives. Soot, which consists of tiny carbon particles, is generated when energy sources such as oil or wood are not completely burned. Soot ...

Filters fitted to vehicle exhaust systems to remove particulate matter pollution have limited impact on ultrafine particles, new research shows. Filters fitted to vehicle exhaust systems to remove ...

Not many people would voluntarily fly through plumes of smoke emitted from wildfires. But atmospheric scientists from the U.S. Department of Energy's Brookhaven National Laboratory do, over and over, ...

As semiconductor devices become more complex and the critical particle size for today’s cutting-edge technology nodes falls into the sub-10 nm size range, controlling and mitigating potentially ...

A philosopher has put forward an argument for rethinking how particles are defined within the standard model of particle ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — must be incomplete, because there are a host of phenomena it cannot ...
