The hydrodynamic radius of a macromolecule or colloid particle is . The macromolecule or colloid particle is a collection of subparticles. This is done most commonly for polymers; the subparticles would then be the units of the polymer. is defined by where is the distance between subparticles and , and where the angular brackets represent an ensemble average. The theoretical hydrodynamic radius was originally an estimate by John Ga… WebWe find that the polymer radius of gyration (Rgpoly), hydrodynamic radius (Rh), and the mixture correlation length (ξ) remain unchanged …
WebIn structural engineering, the two-dimensional radius of gyration is used to describe the distribution of cross sectional area in a beam around its centroidal axis. The radius of gyration is given by the following formula. where I is the second moment of area and A is the total cross-sectional area. The gyration radius is useful in estimating ... WebRg (radius of gyration) – it describes the mass distribution of the object around its centre of gravity. Rs (Stokes or hydrodynamic radius) - It is the radius of an equivalent sphere that diffuses identically to the molecule of interest.

In particular, starting from basic concepts in polymer physics, we derive a relationship between the radius of gyration of a structure and its hydrodynamic ratio, which in turn can be used, for example, to compare a simulated ensemble of confor-mations to NMR diffusion measurements.
Web1 jul. 2014 · The radius of gyration is a general measure of the distribution of an object's mass. The radius of gyration about an axis, raxis r axis, is computed as the root mean square of the distances of the object's component parts from the specified axis. The radius of gyration is related to the mass moment of inertia: raxis = √I axis m r axis = I ...
