A team of researchers has developed a theory to explain how hydrodynamic electron flow could occur in 3D materials and observed it for the first time using a new imaging technique. Electrons flow ...

Flow Imaging Microscopy (FIM), also referred to as Dynamic Image Analysis (DIA), combines the advantages of traditional particle counters with high-resolution imaging to efficiently and expeditiously ...

A low-cost carbon filter reduces arsenic in contaminated well water below safety limits, offering an affordable option for households.

EPFL researchers have shown theoretically that, in highly ordered materials, heat can flow toward warmer regions without violating the laws of thermodynamics. Their work could help design electronics ...
