Water behaves in remarkable ways when heated and pressurized beyond its critical point. Under these extreme conditions, known as supercritical water, it no longer acts like an ordinary liquid. Instead ...

When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of ...

Water, though familiar, still hides astonishing secrets. When squeezed into nanosized channels, it can enter a bizarre “premelting state” that is both solid and liquid at once. Using advanced NMR ...

For the first time, Northwestern University scientists have watched water molecules in real-time as they prepared to give up electrons to form oxygen. In the crucial moment before producing oxygen, ...

Tiny machines built from individual molecules are moving from science fiction into working hardware, promising to reshape ...
