A new paper describes how an accurate statistical description of heterogeneous particulate materials, which is used within statistical micromechanics theories, governs the overall thermo-mechanical properties.
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.
Besides achieving greater resolution and sensitivity, the materials used in these new devices are much cheaper and more versatile than the ones used in current technologies (mainly gold and noble metals) so they could offer a potential alternative in the design of biomedical sensors.
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.
The outcome of science research benefits us all, but knowledge doesn't come cheap. Crowdfunding - promoted by government incentives - may be the best way to meet these costs and garner greater awareness of scientific research priorities.
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.
Chemists have devised an inexpensive, portable sensor that can detect gases emitted by rotting meat, allowing consumers to determine whether the meat in their grocery store or refrigerator is safe to eat.
