13-06-21 The efficient conversion of sunlight into useful energy is one of the challenges which stand in the way of meeting the world's increasing energy demand in a clean, sustainable way without relying on fossil fuels. Photosynthetic(光合作用的) organis...
13-05-29 Quantum communication systems offer the promise of virtually unbreakable encryption(加密) . Unlike classical encryption, which is used to send secure data over networks today and whose security depends on the difficulty of solving mathematical pro...
13-05-09 The latest research from a Kansas State University chemical engineer may help improve humidity and pressure sensors, particularly those used in outer space. Vikas Berry, William H. Honstead professor of chemical engineering, and his research team ar...
13-02-18 A team of researchers at the University of Waterloo's Institute for Quantum Computing has proposed a new computational model that may become the architecture for a scalable quantum computer. In a paper to be published in the journal Science this wee...
13-02-03 The shortened daylight of a Maine winter may make for long, dark nights -- but it has shone a light on a novel experimental approach to fighting inflammatory breast cancer (IBC), an especially deadly form of breast cancer. The new approach enlists t...
12-12-17 While some theoretical physicists make predictions about astrophysics(天体物理学) and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theor...
12-11-08 Even empty gaps have a colour. Now scientists have shown that quantum jumps of electrons can change the colour of gaps between nano-sized balls of gold. The new results, published today in the journal Nature, set a fundamental quantum limit on how t...
12-10-12 At very low temperatures, close to absolute zero, chemical reactions may proceed at a much higher rate than classical chemistry says they should -- because in this extreme chill, quantum effects enter the picture. A Weizmann Institute of Science tea...
12-06-18 Scientists have managed to switch on and off the magnetism of a new material using quantum mechanics, making the material a test bed for future quantum devices. The international team of researchers led from the Laboratory for Quantum Magnetism (LQM...
12-05-21 A pioneering study to gauge(测量,估计) the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through na...
