Definitions

Raney nickel Raney nickel () is a solid catalyst composed of fine grains of a nickel -aluminium alloy , used in many industrial processes. It was developed in 1926 by American engineer Murray Raney Raney, Murray (1927). "Method of producing Finely Divided Nickel ". US Patent 1628190, issued 19 more

Equipartition theorem

Equipartition theorem peptide . The jittery motion is random and complex, and the energy of any particular atom can fluctuate wildly. Nevertheless, the equipartition theorem allows the average kinetic energy of each atom to be computed, as well as the average potential energies of many vibrationa more

Titanium

Titanium Titanium () is a chemical element with the symbol Ti and atomic number 22. It is a light, strong, lustrous, corrosion -resistant (including resistance to sea water and chlorine ) transition metal with a grayish color . Titanium can be alloy ed with other elements such as iron , alumin more

Enzyme

Enzyme of the enzyme TIM , surrounded by the space-filling model of the protein. TIM is an extremely efficient enzyme involved in the process that converts sugar s to energy in the body. Enzymes are protein s that catalyze (i.e. accelerate ) chemical reaction s. In enzymatic reactions, the molec more
