A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 - the purified germanium semiconductor -and now researchers here are on the forefront of a new germanium milestone.
Researchers have long viewed molybdenum sulfide (MoS2) as a promising, much cheaper alternative to platinum. The drawback is that MoS2's catalytic performance is far worse than platinum's. To get around that problem, researchers have been trying to find ways to improve MoS2's catalytic performance. And now they may be on to something.
The photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology represents a first step toward harnessing that lost energy.
The objective of this paper is to explore the relationship between atomic structure and thermal expansion, to study if the thermal expansion coefficient can be predicted in atomic scale and to find how many atoms are sufficient to perform this prediction.
Die Möglichkeiten des Nachstellens hochkomplexer Vorgänge auf der atomaren Ebene mithilfe von genau kontrollierbaren Quantensystemen erforscht eine internationale Forschungsgruppe unter Beteiligung der Freien Universität Berlin.
Researchers have developed so-called nanomimics of host cell membranes that trick the parasites. This could lead to novel treatment and vaccination strategies in the fight against malaria and other infectious diseases.
New technology (the size of a USB memory stick) could revolutionize genomic sequencing of drug-resistant bacteria. Researchers proved the utility of the new device by successfully mapping multi-drug resistance genes in a Typhoid-causing strain of bacteria - which has recently emerged globally. They say that the technology could enable bacterial identification, diagnosis of infectious diseases and detection of drug-resistance at the point of clinical need.
The same research team that developed the first laser based on a living cell has shown that use of fluorescent proteins in a solid form rather than in solution greatly increases the intensity of light produced, an accomplishment that takes advantage of natural protein structures surrounding the light-emitting portions of the protein molecules.
