Permeance, Diffusion and Partition Coefficients: Units and Their Conversion,system are (among others) metre (m), kilogram (kg), mol, seconds (s), Pascal (Pa) and Kelvin (K). This has not always been the case, and before 1960 the CGS system (cm, g, s) was common in the natural sciences. In engineering, a great variety of non-metric units (i.e., inch, pound, fluid ounce, andRejuvenate 发表于 2025-3-23 15:53:23

Water Permeability,spiration at 25°C and 50% humidity is —95MPa, and at lower humidity it is even greater.Water supply is often short. Higher plants, insects and mammals use similar strategies to save water. They have generated membranes of very low water permeability at their interface with the dry air surrounding thexpire 发表于 2025-3-23 22:18:36
Penetration of Ionic Solutes,s the lipophilic pathway. The polymer matrix contains polar polymers which sorb water and swell. This hydration water is continuous, and gives rise to aqueous pores which traverse the cuticle (Sect. 4.5).Waxes occur both sorbed in cutin and as epicuticular wax on the surface of the polymer matrix.

Diffusion of Non-Electrolytes,ility in lipids. Agrochemicals and environmental xenobiotics are often lipophilic, and these compounds are sorbed and accumulate in lipophilic compartments of the environment, such as the organic fraction in soil, the storage lipids of man, animals or plants.

Accelerators Increase Solute Permeability of Cuticles,ion of active ingredients by soil microorganisms. Binding to constituents of the soil is also avoided. Systemic active ingredients must penetrate cuticles before they reach their sites of action in the leaves or in other organs of the plants following translocation (Kirkwood 1999).

Effects of Temperature on Sorption and Diffusion of Solutes and Penetration of Water,e (donor) and enter the membrane phase in which they are sorbed. These sorbed molecules then diffuse in the membrane via a random hopping mechanism. Eventually they arrive at the opposite membrane interface facing the receiver. In cuticles, penetration is complicated, because they consist of more th
