Permselectivity reveals a cool side of nanopores

Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have ...

Microfluidics: The tiny, beautiful tech hidden all around you

When you think of micro- or nanotechnology, you likely think of small electronics like your phone, a tiny robot or a microchip. But COVID-19 tests—which have proven to be central to controlling the pandemic—are also a ...

A Rubik's microfluidic cube

Scientists have recently engineered a modular system based on the Rubik's cube to design and reconfigure microfluidic systems. Research teams had previously pursued the arrangement of microfluidic blocks in diverse conformations ...
