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 ...

'Whiskey webs' are the new 'coffee ring effect'

Spilled coffee forms a ring as the liquid evaporates, depositing solids along the edge of the puddle. This "coffee ring effect" has fascinated scientists for decades, but now a team says they have uncovered the mechanism ...

A nanoscale device to generate high-power terahertz waves

Terahertz (THz) waves fall between microwave and infrared radiation in the electromagnetic spectrum, oscillating at frequencies of between 100 billion and 30 trillion cycles per second. These waves are prized for their distinctive ...

Two-dimensional metals open pathways to new science

An atomically thin materials platform developed by Penn State researchers in conjunction with Lawrence Berkeley National Lab and Oak Ridge National Lab will open a wide range of new applications in biomolecular sensing, quantum ...

Tough, flexible sensor invented for wearable tech

Researchers have used 3-D printing and nanotechnology to create a durable, flexible sensor for wearable devices to monitor everything from vital signs to athletic performance.

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 ...
