Scientists at Oak Ridge National Laboratory recently discovered an unanticipated factor in the performance of polymer-based solar devices that gives new insight on how these materials form and function.
Researchers are developing a disease diagnostic system that offers results that could be read using only a smart phone and a $20 lens attachment. This new device relies on specific chemical interactions that form between something that causes a disease - a virus or bacteria, for example - and a molecule that bonds with that one thing only, like a disease-fighting antibody.
Scientists have built the thinnest-known LED that can be used as a source of light energy in electronics. The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.
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.
