HBT devices are instrumental in helping silicon-based millimetre-wave circuits penetrate what is known as the terahertz (THz) gap. They enable enhanced imaging systems for security, medical and scientific applications, according to the researchers. The team says the HBT devices are very fast and have a fully self-aligned architecture: self-alignment of the emitter, base and collector […]
Plastic for bees? Research shows it works
It is well known that bees play a crucial role in securing food for humans, due to their outstanding pollination activities on plant crops. But the bee population is shrinking and researchers are on a quest to get to the bottom of this problem. A combination of various factors like agricultural chemicals, loss of habitat, […]
Scientists develop techniques to trace cocaine hidden in alcohol
Imaginative techniques aimed at smuggling cocaine, one of the most widely used drugs of abuse, through border controls have been used in recent years, including dissolving cocaine in liquids. A UK man died last year after unknowingly drinking from a contaminated bottle of rum. However, it is currently impossible for customs to check alcohols for […]
Researchers develop method for detailed imaging of fragile bone structures
The researchers from the Technische Universitaet Muenchen (TUM) in Germany, the Paul Scherrer Institute in Switzerland and the Swiss Federal Institute of Technology (ETH-Zurich) said osteoporosis is currently diagnosed almost exclusively by establishing an overall reduction in bone density. This new method will give much greater information about the associated local structure and bone density […]
