An atom-thick graphene membrane for industrial gas separation

Chemical engineers at EPFL have demonstrated for the first time that an atom-thick graphene membrane can separate gas mixtures with a high-efficiency. The "ultimate" membrane is scalable, making it a breakthrough for industrial ...

Researchers probe hydrogen bonds using new technique

Researchers at Carnegie Mellon University have used nuclear resonance vibrational spectroscopy to probe the hydrogen bonds that modulate the chemical reactivity of enzymes, catalysts and biomimetic complexes. The technique ...

Why battery-powered vehicles stack up better than hydrogen

Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. The other 80% is lost through oil extraction, ...

A hydrogen sensor that works at room temperature

Researchers at TU Delft have developed a highly sensitive and versatile hydrogen sensor that works at room temperature. The sensor is made of a thin layer of a material called tungsten trioxide.

Team's pic of crack in the act could prevent engineering failures

In work that could help prevent the failure of everything from bridges to dental implants, a team led by a researcher at Texas A&M University has taken the first 3-D image of a microscopic crack propagating through a metal ...

Astronomers witness slow death of nearby galaxy

Astronomers from The Australian National University (ANU) and CSIRO have witnessed, in the finest detail ever, the slow death of a neighbouring dwarf galaxy, which is gradually losing its power to form stars.
