Computer analysis fills gaps in antibody blueprint

Thu, 11/30/2017 - 16:24
Antibodies defend our bodies against intruders. These molecules consist of proteins with attached sugars. However, the blueprint directing the processing of these sugars on the protein was not well understood until now. Scientists have now used computer analysis to complete this blueprint and confirmed their findings in the laboratory.

The future of electronics: New catalytic effect discovered for producing gallium oxide

Thu, 11/30/2017 - 14:39
Semiconducting oxides are a new class of materials that are currently enjoying great attention in the field of semiconductor technology. Gallium oxide is the archetypal example for its ability to handle extremely high voltages and its optical transparency in the deep ultraviolet region. Such components are based on very thin, ultrapure semiconductor layers produced by special deposition methods. Physicists have now drastically increased the yield of gallium oxide with a catalytic effect observed for the first time during crystal growth.

'Magnetoelectric' material shows promise as memory for electronics

Wed, 11/29/2017 - 18:09
Smartphones and computers wouldn't be nearly as useful without room for lots of apps, music and videos. Devices tend to store that information in two ways: through electric fields (think of a flash drive) or through magnetic fields (like a computer's spinning hard disk). Each method has advantages and disadvantages. However, in the future, our electronics could benefit from the best of each, say researchers.
