3-D printed electrodes free the gas

Alkaline water electrolysis has been touted as a path to establish a hydrogen economy by converting intermittent renewable energies into clean hydrogen-based chemical energy.

Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

Making terahertz waves: Why liquids prefer long optical pulses

Laser-induced ionization in matter—gas, cluster, liquid, and solid—occurs when a laser pulse with sufficient intensity is focused into a target material, creating electrons and ions through nonlinear processes of laser-matter ...

The world of plastics, in numbers

From its early beginnings during and after World War II, the commercial industry for polymers – long chain synthetic molecules of which "plastics" are a common misnomer – has grown rapidly. In 2015, over 320 million tons ...
