Nanocatalysts are catalysts made up of nanoparticles or some other nanostructure such as a nanofoam. A catalyst is a material which increases the rate of a chemical reaction, without itself being altered or changed by the reaction. Nanostructures are engineered structures with features at the nanoscale — between one and 100 nanometers. An obvious advantage…

Nanostructures are engineered structures with features at the nanoscale — between 1 and 100 nanometers. They include nanotextured surfaces, nanoparticles and nanotubes, as well as more complex nano-scale structures. A nanometer (nm) is one billionth of a meter, which is just slightly larger than the atomic scale — individual atoms in a solid are between…

Nanoparticles are engineered particles of between one and 100 nanometers in diameter, a size known as the nanoscale. To put this into context, a nanometer (nm) is one billionth of a meter, and the distance between individual atoms in a solid is between 0.1 nm and 0.4 nm. Nanoparticles therefore range in size from tens…

A Bristol-led team of physicists has found a way to operate mass manufacturable photonic sensors at the quantum limit.

Sensors to detect viruses, explosives or drugs often use a technique called surface-enhanced Raman spectroscopy (SERS) in which light wavelengths from a chemical or biological species adsorbed on metal nanostructures are detected and mapped to the identity of the species. In SERS, detection efficiency depends on the surface morphology of the nanostructure. Now, scientists have…

Nanoengineering deals with structures at the nanoscale — between one and 100 nanometers. A nanometer (nm) is one billionth of a meter, and the distance between individual atoms in a solid is between 0.1 nm and 0.4 nm. The nanoscale is therefore about as small as materials can get, without becoming individual atoms. Nanotechnology and…
