'Swiss cheese' membrane with adjustable holes

A new membrane, developed by University of Twente scientists, can be made more or less porous 'on demand'. In this way, smart switching between 'open' and 'closed' is possible, which opens the way to innovative applications ...

Water purification at the molecular level

(Phys.org) —Fracking for oil and gas is a dirty business. The process uses millions of gallons of water laced with chemicals and sand. Most of the contaminated water is trucked to treatment plants to be cleaned, which is ...

Student develops filter for clean water around the world

Roughly 780 million people around the world have no access to clean drinking water. According to the World Health Organization (WHO), 3.4 million people die from water-related diseases every year. ETH student Jeremy Nussbaumer ...

Hollow-fiber membranes could cut separation costs, energy use

Researchers have developed a microfluidic technique for fabricating a new class of metal-organic framework (MOF) membranes inside hollow polymer fibers that are just a few hundred microns in diameter. The new fabrication ...

Additive stops aging in super glassy polymer membranes

(Phys.org) —Putting a stop to aging has now been made possible for highly porous polymer membranes whose efficiency in the separation of gases falls off fast when parts of their polymer chains rearrange, as so do their ...

Tests prove electrolytic cells are stable at 850 degrees

Siemens researchers have demonstrated the long-term stability of ceramic electrolytic cells that are used to produce hydrogen. The results represent a step in the development of new energy storage systems. The use of electricity ...
