Thanks to the math behind supersymmetry theory, engineers have achieved single-mode lasing from such a microlaser array. By calculating the necessary properties for 'superpartner' arrays, they can cancel out the unwanted extra modes.
Five years after introducing see-through wood building material, researchers have taken it to another level. They found a way to make their composite 100 percent renewable - and more translucent - by infusing wood with a clear bio-plastic made from citrus fruit.
Researchers have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side.
A study shows that graphene oxide nanomaterials, alone and combined with polycyclic aromatic hydrocarbons, pose a potential source of toxicity to fish, but at concentrations that are above the currently expected environmental levels.
