Ångstrom-depth resolution with chemical specificity at the liquid-vapor interface

Surfactants play an important role in every day life, for instance as major components in soaps. Since they feature hydrophilic and hydrophobic parts in their structure, they accumulate at water interfaces with air and can ...

Harpoons, robots and lasers: How to capture defunct satellites and other space junk and bring it back to Earth

More than half of the thousands of satellites in orbit are now defunct, and this accumulation of floating space debris has been described as a "fatal problem" for current and future space missions and human space travel.
