Nanoclusters
Nanoclusters have at least one dimension between 1 and 10 nanometers and a narrow size distribution. Scientists from the research center Forschungszentrum Rossendorf (Germany) use the survival mechanism of special bacteria to produce solid nanoclusters out of palladium. Bacteria-based nanoclusters ideally suited for building new nano-catalysts.
A new instrument of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University control the size of nanoclusters of 10 to 100 atoms with atomic precision. They created a model nanocatalyst of molybdenum sulfide which is used in hydrodesulphurization. Hydrodesulphurization is a process that removes sulphur from natural gas and petroleum products to reduce pollution.
