Lattice constant - Wikipedia

The lattice constant, or lattice parameter, ... However, the full set of lattice parameters consist of the three lattice constants and the three angles between them. For example, The lattice constant for diamond is a = 3.57 Å at 300 K. The structure is equilateral although its actual shape cannot be determined from only the lattice constant. Furthermore, in real applications, typically the ...

In thiourea, the recoveries for Zn and Pb were low, however 99 % Cu can be recovered. In regard to the economy, the extraction of Cu, Pb and Zn was studied in this work with the aspect of minimal energy consumption during milling. The maximum recoveries of non-ferrous metals in the solutions of ferric chloride and thiourea were found with the minimal grinding energy of 403 kWht-1. A favourable ...

Superoxide dismutase - Wikipedia

Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O 2 −) radical into ordinary molecular oxygen (O 2) and hydrogen peroxide (H 2 O 2).Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging and is degraded by other ...
