Hydrodynamics of concentrated proteoglycan solutions.

Structure of Concentrated HCl Solutions

A pentagonal ring is suggested as the basic structural unit of HCl(H2O)6 and (HCl)2(H2O)6 in solution. Modeled after the X-ray structure of a caged H13O6 compound, it contains bridged H5O2 and Clions, each with a coordination number around four. In the most concentrated HCl solutions, one of the ligands solvating Clis HCl, giving rise to a bichloride moiety. The proposed structure explains qual...

Analytic solutions of hydrodynamics equations

Many similarity solutions have been found for the equations of one-dimensional (1-D) hydrodynamics. These special combinations of variables allow the partial differential equations to be reduced to ordinary differential equations, which must then be solved to determine the physical solutions. Usually, these reduced ordinary differential equations are solved numerically. In some cases it is poss...

Multicomponent Concentrated Aqueous Electrolyte Solutions

New exact solutions of relativistic hydrodynamics

A new class of simple and exact solutions of relativistic hydrodynamics is presented, and the consequences are explored in data analysis. The effects of longitudinal work and acceleration are taken into account in an advanced estimate of the initial energy density and the life-time of the reaction.

Component dynamics in polyvinylpyrrolidone concentrated aqueous solutions.

(2)H-nuclear magnetic resonance (NMR) and neutron scattering (NS) on isotopically labelled samples have been combined to investigate the structure and dynamics of polyvinylpyrrolidone (PVP) aqueous solutions (4 water molecules/monomeric unit). Neutron diffraction evidences the nanosegregation of polymer main-chains and water molecules leading to the presence of water clusters. NMR reveals the s...
