The dark-blue phosphorus-containing heteropolymolybdate P[Mo 12 O 40] 3− is used for the spectroscopic detection of phosphorus. [31] The broad range of oxidation states of molybdenum is reflected in various molybdenum chlorides: [26] Molybdenum(II) chloride MoCl 2, which exists as the hexamer Mo 6 Cl 12 and the related dianion [Mo 6 Cl 14] 2-.
Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...
The name honors the French Engineer Henry Darcy who first described the flow of water through sand filters for potable water supply. Permeability values for most materials commonly range typically from a fraction to several thousand millidarcys. The unit of square centimetre (cm 2) is also sometimes used (1 cm 2 = 10 −4 m 2 ≈ 10 8 d).
The Fermi liquid is qualitatively analogous to the non-interacting Fermi gas, in the following sense: The system's dynamics and thermodynamics at low excitation energies and temperatures may be described by substituting the non-interacting fermions with interacting quasiparticles, each of which carries the same spin, charge and momentum as the original particles.
Diamagnetism is a property of all materials, and always makes a weak contribution to the material's response to a magnetic field. However, other forms of magnetism (such as ferromagnetism or paramagnetism ) are so much stronger such that, when different forms of magnetism are present in a material, the diamagnetic contribution is usually ...
Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility). The magnetic moment induced by the applied field is linear in the field strength, and it is rather weak. It typically requires a sensitive analytical balance to detect the ...
Mottness – Materials classically predicted to be conductors, that are actually insulators; Quantum spin liquid – Phase of matter; Ferromagnetism – Mechanism by which materials form into and are attracted to magnets; Diamagnetism – Magnetic property of ordinary materials
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
