Scientists are working on storing and processing information on the level of single molecules to create the smallest possible components that will combine autonomously to form a circuit. As recently reported, the researchers can switch on the current flow through a single molecule for the first time with the help of light.
The University of Nebraska-Lincoln has earned a $9.6 million grant from the National Science Foundation to support its Materials Research Science and Engineering Center and its nanotechnology research through 2020.
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.
