Future flash memory could be faster and store more data without changing its basic design by using a clever nanocrystal material. Scientists propose a new logical element made with the rare earth material gadolinium.
Scientists have shown that magnetic memory, logic and sensor cells can be made faster and more energy efficient by using an electric, not magnetic, field to flip the magnetization of the sensing layer only about halfway, rather than completely to the opposite direction.
Using powerful lasers, physicists have discovered a new way to recognize currents of spinning electrons within a semiconductor. Their findings could lead the way to development of superior computers and electronics.
Scientists report progress in using a common virus to develop improved materials for high-performance, rechargeable lithium-ion batteries that could be woven into clothing to power portable electronic devices.
Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary to use other molecules as messengers.
The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers have now discovered how to control this effect in nanoscale semiconductors called "quantum dots," enabling the development of incredibly tiny new products.
Researchers have developed a nano-sized vehicle that can deliver chemotherapy drugs directly into cancer cells while avoiding interaction with healthy cells. The vehicle is very similar to a 'cluster bomb' and can be used to treat many different types of tumors, including lung, blood, colon and brain cancers.
