Even in a crowded room full of background noise, the human ear is remarkably adept at tuning in to a single voice—a feat that has proved remarkably difficult for computers to match. A new analysis of the underlying mechanisms, ...

Adding a polymer stabilizes collapsing metal-organic frameworks

Metal-organic frameworks (MOFs) are a special class of sponge-like materials with nano-sized pores. The nanopores lead to record-breaking internal surface areas, up to 7800 m2 in a single gram. This feature makes MOFs extremely ...

'Swiss cheese' membrane with adjustable holes

A new membrane, developed by University of Twente scientists, can be made more or less porous 'on demand'. In this way, smart switching between 'open' and 'closed' is possible, which opens the way to innovative applications ...
