Molecular buoyancy and osmotic equilibrium.

چکیده
Measurements of osmotic equilibrium of colloidal solutions, ranging from 170,000 to 20,000 in molecular weight, show that the negative buoyancy of the solute molecules is additive to the osmotic pressure. Seen together with earlier measurements of positive buoyancy of oil suspensions, these data confirm that the osmotic interaction between solute and solvent at equilibrium is purely a force-coupling at the free surface.

Water transport in aquaporins: molecular dynamics simulations.
Aquaporins and aquaglyceroporins are membrane channel proteins that selectively transport water and small molecules such as glycerol across biological membranes. Molecular dynamics simulations have made substantial contributions toward understanding the permeation mechanisms of aquaporins in atomic detail. Osmotic pressure is the driving force of the transport by aquaporins. The osmotic water p...
متن کاملDynamics of osmotic fluid flow
The classical thermodynamic treatment of osmotic pressure is quite sufficient to describe equilibrium situations and compute most quantities of interest without reference to any molecular model (see, for example, Finkelstein, 1987). However, one's intuition is always aided by molecular models, and a microscopic picture can be quite useful when thinking about osmotic flow in unfamiliar situation...
متن کاملPoroelastic bulk properties of the tectorial membrane measured with osmotic stress.
The equilibrium stress-strain relation and the pore radius of the isolated tectorial membrane (TM) of the mouse were determined. Polyethylene glycol (PEG), with molecular mass (MM) in the range 20-511 kDa, added to the TM bathing solution was used to exert an osmotic pressure. Strain on the TM induced by isosmotic PEG solutions of different molecular masses was approximately the same for MM > o...
متن کاملCore histone associations in solutions of high salt. An osmotic pressure study.
We have measured the concentration dependence of the osmotic pressure for solutions of core histones in 2.0 M NaC1, pH 8.0, over the concentration range from 1 to 20 mg/ml at 25°C. The ratio of the osmotic pressure to the protein concentration is nearly constant over this range, with a value corresponding to an apparent number average molecular weight of 75,000. Gel filtration of a typical core...
متن کاملSwelling and collapse of polyelectrolyte gels in equilibrium with monovalent and divalent electrolyte solutions.
The swelling of polyelectrolyte (PE) gels by 1:1 and 2:1 salts is studied via osmotic ensemble Monte Carlo simulations at constant osmotic pressure and electrolyte chemical potential of a reservoir phase in equilibrium with a model PE network. Large molecular weight gels exhibit a remarkable swelling response to small changes in 2:1 salt concentration. Gel collapse is accompanied by the formati...
