(Phys.org)—Self-assembled monolayers are organic molecules that spontaneously coordinate to a metal surface. If this metal surface is an electrode, then a current can pass through the organic monolayer and interact with ...
(Phys.org) —Angela Hight Walker of PML's Semiconductor and Dimensional Metrology Division and colleagues have succeeded in measuring a previously unknown but essential property − thermal conductivity −of an ultra-thin ...

(Phys.org) —Most materials behave very differently in bulk (3D) form than they do in monolayer (2D) form. The difference occurs because of weak forces holding the multiple layers of a bulk material together, which results ...
Cells are very good at protecting their precious contents—and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective ...
