New Laser-Based Method for Measuring Millimeter Distances More Accurately than Ever

A new laser-based method for measuring millimeter distances more accurately than ever before - with an uncertainty of 10 picometers (trillionths of a meter) - has been developed and demonstrated by a physicist at the National Institute of Standards and Technology (NIST).

Researchers Expand the Tool Kit of Colloid Particles Making New Coloured Finishes Possible

Scientists at the Max Planck Institute of Colloids and Interfaces have used ion bombardment and gold metallisation to produce a new family of particles whose bonding behaviour can be chemically tailored. With these particles, scientists hope not only to be able to perform better research on the dynamics of solids and molecules. The discovery could also bring about, among other things, the development of new finishes which change their colour with temperature.

Exponential Decay Lifetimes of Excitons in Individual Single-Walled Carbon Nanotubes

Carbon nanotubes have shown great promise for creating single-molecule biosensors for detecting disease, mostly a result of the fact that the electrical conductivity of a carbon nanotube changes markedly when they bind to specific molecules.
