Taking advantage of a germanium wafer coated with a layer of virtually pristine graphene a team of engineers has devised a simpler, reproducible and less expensive manufacturing approach using directed self-assembly.
Scientists have harnessed a scanning transmission electron microscope (STEM) to directly write tiny patterns in metallic ink, forming features in liquid that are finer than half the width of a human hair.
Researchers have managed to synthesize and characterize two previously unknown, record-large silver nanoclusters of 136 and 374 silver atoms. These diamond-shaped nanoclusters, consisting of a silver core of 2 to 3 nanometers and a protecting layer of silver atoms and organic thiol molecules, are the largest ones whose structure is now known to atomic precision.
To understand how molecules undergo light-driven chemical transformations, scientists need to be able to follow the atoms and electrons within the energized molecule as it gains and loses energy. In a recent study, a team of researchers used ultrafast high-intensity pulsed X-rays to take molecular snapshots of these molecules.
New findings suggest that a few-atoms thin titanium carbide, one of about 20 two-dimensional materials of MXene family, can be more effective at blocking and containing electromagnetic interference, with the added benefit of being extremely thin and easily applied in a coating just by spraying it onto any surface - like paint.
