Virial coefficients are fundamental parameters in the statistical description of fluids, encapsulating the effects of molecular interactions on macroscopic thermodynamic properties. Through the virial ...

THE second virial coefficient of krypton was determined for temperatures ranging from 109.95° K. to 270.3° K. The experimental technique has been described 1,2; one measures the difference between the ...

One of the challenges in biopharmaceutical development is measuring the 3-d structure of the active protein. The diffraction of X-ray beams through a crystalline structure can be measured to produce a ...

Abstract: A virial relation is an integral identity involving the solution of a differential equation. The identity can be derived from the equation itself or, if the equation can be formulated as a ...

The new, international theoretical study introduces a novel approach known as the ‘quantum virial expansion,’ offering a powerful tool to uncover the complex quantum interactions in two-dimensional ...

Static light scattering (SLS) is a non-invasive technique used for characterizing macromolecules in solution. A beam of monochromatic light is directed through a sample and the intensity of the light ...

Dynamic light scattering (DLS) is a technique used to determine particle size distributions of bioformulations. Traditionally, DLS measurements have been used for studying dilute solutions, but ...
