A catalyst can be switched on and off using mechanical means.
Wrapping Single-Walled Carbon Nanotubes (SWNTs) with a molecular sleeve made from an analog of Vitamin B2 protects the SWNTs from defects caused by oxygen and renders them much more useful for nanotech applications.
DNA origami structures act as seeds to program the construction of structures up to 100 times larger.
A major advance in molecular machine fabrication allows the construction of rotaxane molecular shuttles in which organic and inorganic components are mechanically linked in the same molecular structure.
20 years ago, in the wake of the cold fusion excitement-turned-debacle, I noticed an interesting fact. The people doing the experiments were divided into two classes: The electrochemists who believed that fusion was happening were doing their experiments in plastic tubs and glassware, whereas the physicists who believed that no fusion was really happening were… Continue reading "Cold fusion" redux?
An atomic force microscope (AFM) can be used to write and erase two-nanometer-thick conducting lines at the interface between atomic layers of two different metal oxide insulators.
The discovery that nitrogen-doped, metal-free carbon nanotubes make better electrodes than do platinum nanoparticles may open the way for inexpensive nanotech fuel cells.
A sawing and annealing process that creates regular nanoscale features on the surface of a sapphire crystal promises a way of making nanotech memories of up to 10 Terabits per square inch without the need of photolithography.
Two independently controlled nanomechanical devices can be positioned on a two-dimensional DNA grid so that they can cooperate to capture between them one of four DNA building blocks, determined by which of two possible states each device is set to.
Advances in using amorphous metal alloys may make possible an inexpensive nanotech version of the molding technique used to make DVDs.
