71Compounds of berkelium — Berkelium(IV) oxide Berkelium forms a number of chemical compounds where it normally exists in an oxidation state of +3 or +4 and behaves similarly to its lanthanide analogue, terbium. Contents …
72Dimensional analysis — In physics and all science, dimensional analysis is a tool to find or check relations among physical quantities by using their dimensions. The dimension of a physical quantity is the combination of the basic physical dimensions (usually mass,… …
73Synthetic diamond — Synthetic diamonds of various colors grown by the high pressure high temperature technique Synthetic diamond is diamond produced in a technological process; as opposed to natural diamond, which is created in geological processes. Synthetic… …

75Diffusion creep — refers to the deformation of crystalline solids by the diffusion of vacancies through their crystal lattice.[1] Diffusion creep results in plastic deformation rather than brittle failure of the material. Diffusion creep is more sensitive to… …
76Geometrically frustrated magnet — Geometrical frustration and ice rules The word frustration was introduced to describe the situation where a system cannot simultaneously minimize the interaction energies between its components [cite journal last = Schiffer first = P. authorlink …
77Classical XY model — The classical XY model (sometimes also called classical rotor (rotator) model or O(2) model) is a model of statistical mechanics. It is the special case of the n vector model for n = 2. Contents 1 Definition 2 General properties 2.1 One dimension …
78Electrical resistance — is a ratio of the degree to which an object opposes an electric current through it, measured in Ohms. Its reciprocal quantity is electrical conductance measured in Siemens. Assuming a uniform current density, an object s electrical resistance is… …
