Properties of silk III fibroin at the air-water interface
The silk macromolecule fibroin is used in biomedicine in the silk I and II conformations, which have well characterized structures and properties. It was hypothesized that the fibroin crystalline structure silk III could have similar properties. This research assessed key properties of silk III fibroin to facilitate future manufacture and biomedical applications.
Surface morphology and electrical properties of GaN layers
Gallium nitride is a semiconductor used in a number of electronic devices. This study observes the growth of gallium nitride crystals at high temperatures, opening the way for further research into techniques to improve the quality and effectiveness of transistors.
