Virial coefficient — Virial coefficients B i appear as coefficients in the virial expansion of the pressure of a many particle system in powers of the density. They are characteristic of the interaction potential between the particles and in general depend on the… … Wikipedia
Virial expansion — The classical virial expansion expresses the pressure of a many particle system in equilibrium as a power series in the density.The virial expansion was introduced in 1901 by Heike Kamerlingh Onnes as a generalization of the ideal gas law. He… … Wikipedia
Virial theorem — In mechanics, the virial theorem provides a general equation relating the average over time of the total kinetic energy, , of a stable system consisting of N particles, bound by potential forces, with that of the total potential energy, , where… … Wikipedia
Noro–Frenkel law of corresponding states — The Noro–Frenkel law of corresponding states is an equation in thermodynamics that describes the critical temperature of the liquid gas transition T as a function of the range of the attractive potential R. It states that, all short ranged… … Wikipedia
Static light scattering — is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein. Measurement of the scattering intensity at many angles allows… … Wikipedia
Amagat's law — or the Law of Partial Volumes of 1880 describes the behaviour and properties of mixtures of ideal (as well as some cases of non ideal) gases. Of use in chemistry and thermodynamics, Amagat s law states that the volume Vm of a gas mixture is equal … Wikipedia
Theta solvent — In a polymer solution, a theta solvent (or θ solvent) is a solvent in which polymer coils act like ideal chains, assuming exactly their random walk coil dimensions. Thermodynamically, the excess chemical potential of mixing between a polymer and… … Wikipedia
Boyle temperature — In thermodynamics, the Boyle temperature is defined as the temperature for which the second virial coefficient, B {2}(T) vanishes, i.e. B {2}(T)=0. Since higher order virial coefficients are generally much smaller than the second coefficient, the … Wikipedia
Hard spheres — are widely used as model particles in the statistical mechanical theory of fluids and solids. They are defined simply as impenetrable spheres that cannot overlap in space. They mimic the extremely strong repulsion that atoms and spherical… … Wikipedia
Methods to investigate protein–protein interactions — There are many methods to investigate protein–protein interactions. Each of the approaches has its own strengths and weaknesses, especially with regard to the sensitivity and specificity of the method. A high sensitivity means that many of the… … Wikipedia
