After that, the chapter introduces the measurement of osmotic pressure, which involves osmometer, semipermeable membrane, the method of measurement, and more. Based on the principle of osmotic pressure, one of the most important technologies, that is, reverse osmosis and its applications in water ...
aThis movement is called osmosis: osmotic pressure is the force that causes water to flow across a membrane to the side with a higher concentration of ions. 这运动称渗透作用: 渗透压是造成水横跨膜流动对边以离子的更高的浓度的力量。[translate]...
osmotic pressure (redirected fromosmotic pressures) Thesaurus Medical Encyclopedia Related to osmotic pressures:tonicity osmotic pressure n. The pressure exerted by the flow of water through a semipermeable membrane separating two solutions with different concentrations of solute. ...
The Characteristics of the osmotic solutions are needed for the optimization of mass transfer during osmotic process, and for the improvement of final product quality. The vant Hoff equation and Gibbs Duhem theorem are commonly used to estimate osmotic pressure and solute activity. Water activities ...
Osmotic pressure modulates single cell cycle dynamics inducing reversible growth arrest and reactivation of human metastatic cells Article Open access 29 June 2021 Introduction When a difference between intracellular and extracellular osmolality develops, cells inevitably become swollen or shrunken following os...
In 1877, Pfeffer used a semipermeable membrane to separate sugar solution from pure water and found that osmotic pressure is proportional to the solute concentration and temperature. It was Van't Hoff who identified the proportionality between osmotic pressure, solute concentration, and temperature. ...

Defrozen raspberries were osmotically dehydrated in sucrose solution initially at low pressure (1.33 kPa for 8 min), and then at ambient pressure (4 h). Moisture decreased from 84% to 49% (wet basis), and almost one half of water removal occurred at the vacuum period. Two different transpo...
