A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices - too small to see without a microscope - use opposing magnetic and electrophoretic forces to precisely stretch the cells and molecules, holding them in position so that the activity of receptors and other biochemical activity can be studied.
A team of physicists has mapped the inner atomic workings of a compound within the mysterious class of materials known as spin-orbit Mott insulators. The findings confirm the properties that theorists predict could lead to discoveries in superconductivity, the topological phases of matter and new forms of magnetism.
Applications are open for the allocation of one research fellowship, under the project 'Nanomaterials for the uptake of pollutant metal ions: efficiency, selectivity and recyclability' from the Associate Laboratories CICECO and CESAM of the University of Aveiro.
Flawed but colorful diamonds are among the most sensitive detectors of magnetic fields known today, allowing physicists to explore the minuscule magnetic fields in metals, exotic materials and even human tissue.
The multi-university project is aimed at designing more durable and cost-effective alloys for tomorrow's military vehicles; the award also will fund the development of new magnesium alloys that do not require expensive and scarce rare earth elements.
Researchers have made major improvements in computer processing using an emerging class of magnetic materials called 'multiferroics,' and these advances could make future devices far more energy-efficient than current technologies.
