Researchers have shown they can replace the lithium ions, each of which carries a single positive charge, with magnesium ions, which have a plus-two charge, in battery-like chemical reactions, using an electrode with a structure like those in many of today's devices.

A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels.

For a condition such as epilepsy, it is essential to act at exactly the right time and place in the brain. For this reason, researchers have developed an organic electronic micropump which, when combined with an anti-convulsant drug, enables localized inhibition of epileptic seizure in brain tissue in vitro.

Light must travel in a straight line and at a constant speed, or so the laws of nature suggest. Now, researchers have demonstrated that laser light traveling along a helical path through space, can accelerate and decelerate as it spins into the distance.

This new technique, termed coaxial lithography (COAL), offers a combination of radial and longitudinal degrees of compositional freedom within the nanowire. Synthetic control over the radial dimension combined with the possibility of selectively deleting features used to build the nanowires significantly expands the range of architectures that can be synthesized using COAL.
