  • 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 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

  • Polymer — Appearance of real linear polymer chains as recorded using an atomic force microscope on surface under liquid medium. Chain contour length for this polymer is 204 nm; thickness is 0.4 nm.[1] A polymer is a large molecule (macromolecule …   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

  • Protein-protein interaction — Protein protein interactions refer to the association of protein molecules and the study of these associations from the perspective of biochemistry, signal transduction and networks. The interactions between proteins are important for many… …   Wikipedia

  • Absolute molar mass — is a process to determine the characteristics of molecules. TOC History The first absolute measurements (i.e. made without reference to standards) were based on fundamental physical characteristics and their relation to the molar mass. The most… …   Wikipedia
