Scientists report on nanofibers, which enable for the first time a directed energy transport over several micrometers at room temperature. This transport distance can only be explained with quantum coherence effects along the individual nanofibers.
Researchers have developed tiny nanocrystals that could be used in the next generation of medical imaging technologies to light up cancer cells. In a new study, the team of researchers describe how they make these films which are based on the heavy metals lanthanum and europium.
Advances in manufacturing technology for quantum dots may soon lead to a new generation of LED lighting that produces a more user-friendly white light, while using less toxic materials and low-cost manufacturing processes that take advantage of simple microwave heating.
Researchers have made a surprising discovery about hybrid organic/inorganic solar cells. Contrary to expectations, a diode composed of the conductive organic PEDOT:PSS and an n-type silicon absorber material behaves more like a pn junction between two semiconductors than like a metal-semiconductor contact (Schottky diode).
Researchers used a synchrotron X-ray source to investigate the existence of instabilities in the arrangement of the electrons in metals as a function of both temperature and pressure, and to pinpoint, for the first time, how those instabilities arise.
One of the striking features of self-organization in biomolecular systems is the capacity of assemblies of filamentous particles for synchronous motion. Physicists now provide new insights into how such movements are coordinated.
