Metal patterns printed on a III-V semiconductor material can control the appearance and positions of droplets arising on its surface when heated. The result is a significant step forward for controlled device fabrication on a chip.
Researchers at Linköping University in Sweden are developing a promising new method to selectively convert carbon dioxide and water to various types of fuel. Driving this reaction is solar energy. The recent study, published in ACS Nano, combines the material graphene and the semiconductor cubic silicon carbide in a process which essentially mimics photosynthesis in plants.
Scientists demonstrated a strong coupling of very thin ferromagnetic permalloy layers to the antiferromagnetic spintronics compound Manganese Gold. This enabled them to apply well-established read-out methods commonly applied to ferromagnets in antiferromagnetic spintronics as well.
A team from the Swedish company Alfa Laval used MAX IV beamline MAXPEEM to gain unprecedented insights on the oxide layer of stainless steel. The information they obtained will be highly beneficial for the company’s R&D activities.
