A team of physicists has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes, it is possible to change the resistance and the resonant frequency of the diode.
Scientists have discovered more details about the way certain materials hold a charge even after two surfaces separate, information that could help improve devices that leverage such energy as a power source.
Engineers have devised a new method of measuring the stickiness of micro-scale surfaces. The technique could be useful in designing and building micro-electro-mechanical systems (MEMS), devices with microscopic moving parts.
In a rare move, a researcher is sharing his recipe for a new, more affordable way to make nanoparticles. This will empower any laboratory in the world to easily create similar nanoparticles and could lead to a whole new way of delivering biotherapeutic drugs and do it more quickly.
Scientists have developed a new strategy for dense, unobtrusive labeling of proteins. They utilize an inert peptide-tag in combination with a high affinity nanobody for close-grained fluorophore tagging with minimal linkage errors.
