A catalyst's utility is influenced by its surface charge and how that charge is transferred. Until recently, studying charge transfer has relied on complex imaging techniques that are both expensive and time-consuming. Scientists now report an approach for studying charge transfer that does not rely on complicated equipment — simplifying the real-time observation of catalysis.

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 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 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.
Read moreA team of acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can also 'swallow' low frequencies very well, as they report.
Read moreResearchers have fabricated a self-assembled, carbon-based nanofilm where the charge state (ie, electronically neutral or positive) can be controlled at the level of individual molecules. Molecular self-assembly on a metal results in a high-density, 2D, organic quantum-dot array with electric-field-controllable charge state, with the organic molecules used as 'nano-sized building blocks' in fabrication of functional nanomaterials. Achieved densities are an order of magnitude larger than conventional inorganic systems.
