How impermeable is the impermeable graphene?

New experiments by researchers at The University of Manchester have placed the best limits yet on impermeability of graphene and other two-dimensional materials to gases and liquids. The work has also revealed that the carbon ...

New carbon membrane generates a hundred times more power

Leiden chemists have created a new ultrathin membrane only one molecule thick. The membrane can produce a hundred times more power from seawater than the best membranes used today. The researchers have published their findings ...

Water was a winner in capturing carbon dioxide

Climate worries go hand in hand with CO2 emissions concerns. Emissions hit an all-time high last year. The CO2 level in the atmosphere may be higher than it's been in 3 million years.

Colorful solution to a chemical industry bottleneck

The nanoscale water channels that nature has evolved to rapidly shuttle water molecules into and out of cells could inspire new materials to clean up chemical and pharmaceutical production. KAUST researchers have tailored ...

Using bacteria to create a water filter that kills bacteria

More than one in 10 people in the world lack basic drinking water access, and by 2025, half of the world's population will be living in water-stressed areas, which is why access to clean water is one of the National Academy ...

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 ...
