For better batteries, just add water

Lithium-ion batteries are now found everywhere in devices such as cellular phones and laptop computers, where they perform well. In automotive applications, however, engineers face the challenge of squeezing enough lithium-ion ...

Hybrid copper-gold nanoparticles convert CO2

Copper -- the stuff of pennies and tea kettles -- is also one of the few metals that can turn carbon dioxide into hydrocarbon fuels with relatively little energy. When fashioned into an electrode and stimulated with voltage, ...

Chip simulates metabolism of medicine in human body

(PhysOrg.com) -- A tiny electrochemical cell, developed by researchers of the MESA+ Institute for Nanotechnology, The Netherlands, is able to mimick the behaviour of medicine inside a human body. This chip is presented in ...

Adjusting acidity with impunity

(PhysOrg.com) -- How do individual cells or proteins react to changing pH levels? Researchers at the MESA+ Institute for Nanotechnology at the University of Twente, The Netherlands, have developed a technique for ‘gently’ ...

On-the-go ultrahigh vacuum storage systems

The train to Tsukuba, Japan often carries workers with briefcases and travelers with overnight bags, but recently a group of scientists took an unusual bit of luggage on board: a suitcase with an ultrahigh vacuum chamber ...
