A team chemically engineered carbon nanotubes to synthesize and trap trions at room temperature. Trions are quasi particles that can potentially carry more information than electrons in applications from bioimaging to chemical sensing and quantum computing. The research makes it possible to manipulate trions and study their fundamental properties in ways that have never been possible before.
Read moreThe researchers used machine-vision automation and parallelization to simultaneously produce globally aligned, single-wall carbon nanotubes using pressure-driven filtration.
Read moreScientists are studying the fabrication of polymeric nanofibers and microfibers — very thin fibers made up of polymers. The fibers can be woven into textile-like structures but depending on the use, different fiber thicknesses may be necessary. To study the effects of various parameters on fiber fabrication, the researchers compared the characteristics of fibers created in different ways.
Read moreA phenomenon that has previously been seen when researchers simulate the properties of planet cores at extreme pressures has now also been observed in pure titanium at atmospheric pressure. Chains of atoms dash around at lightning speeds inside the solid material.
Read moreUsing a range of theoretical and simulation approaches, physicists have shown that liquids in contact with substrates can exhibit a finite number of classes of behavior and identify the important new ones.
Read moreAn oscillation assisted digital light processing (DLP) based 3D printing approach is developed to enable ultrafast fabrication of microlens arrays with optically smooth surface (1 nm surface roughness) via a single 1-3 seconds exposure of grayscale UV light.
Read moreCalcium-based batteries promise to reach a high energy density at low manufacturing costs. This lab-scale technology has the potential for replacing lithium-ion technology in future energy storage systems. Using the electrolytes available, however, it has been impossible so far to charge calcium batteries at room temperature. Researchers of Karlsruhe Institute of Technology (KIT ) now present a promising electrolyte class, with which this will be possible.
Read moreElectromagnetism was discovered 200 years ago, but the origin of the very large electromagnetic fields in the universe is still a mystery.
Read moreTiny magnetic vortices known as skyrmions form in certain magnetic materials, such as Cu2OSeO3. These skyrmions can be controlled by low-level electrical currents — which could facilitate more energy-efficient data processing. Now a team has succeeded in developing a new technique at the VEKMAG station of BESSY II for precisely measuring these vortices and observing their three different predicted characteristic oscillation modes (Eigen modes).
Read moreTungsten diselenide emits light with very special properties. Nobody could tell why — but now, scientists have solved the riddle: a combination of atomic defects in the material and microscopic distortion is responsible for the remarkable effect.
