In a bid to improve the technology utilized by cleanup crews to manage and contain such large spills, researchers have invented a smart nanofiber-based oil-scavenging material or supergelators that could help clean up oil spills efficiently and rapidly to prevent secondary pollution.
By doping a thermoelectric material with minute amounts of sulfur, a team of researchers has found a new path to large improvements in the efficiency of materials for solid-state heating and cooling and waste energy recapture.
Graphene on silicon carbide could be an interesting candidate for future spintronics components. Squeezing gold atoms between the semiconducting substrate and graphene does enhance spin-orbit interaction at hot spots and shows ways to controll the spins.
Like drums in regular drumsets, graphene membranes at the nanoscale possess a distinct set of oscillating modes that correspond to specific oscillation frequencies. The modes can be excited by applying an external voltage.
A single drop with the volume of a millionth of a litre is really not very large and certainly does not look like something you can do a lot with. However, a simple device can split the microdroplet into a collection of equally-sized nanodroplets.
