Muon Precession used for mapping magnetism. Muon spins can be used to map magnetic fields inside superconductors. The best yet measurement of the gravitational constant, G, provides a higher precision mass for the Earth. The use of a gated probe helps to sharpen STM spectroscopy of small gold clusters. Carbon nanotubes, used as emitters of electrons, have been fashioned into a full-color display.
New simulations suggest that very thin gold nanowires are actually zigzag shaped.
A single carbon nanotube, bestriding three gold electrodes, has been made into a diode by doping one half of the nanotube. Quantized vortices have been observed in Bose Einstein condensates of rubidium atoms. Freestanding single carbon nanotubes can now be grown on a grid pattern. A new method using nonlinear optics allows the imaging of low-contrast biological samples. A striking stepwise change in friction occurs when an atomic force microscope probe is scraped across a monolayer of strandlike molecules.
