Cherniak (2010b) reviews diffusion in the accessory minerals zircon, monazite, apatite, and xenotime, phases important in geochronologic studies. Diffusion in other minerals, including carbonates, sulfide minerals, fluorite and diamond, is reviewed by Cherniak (2010c).
Diffusion and Transport Across Cell Membranes II. LIPID DIFFUSION: THE MAJOR MEANS OF DRUG ABSORPTION AND PERMEATION The rate at which a molecule diffuses across a membrane depends on its size and its degree of hydrophobicity (Fig. 2). Hydrophobic substances such as gases and steroid hormones diffuse across membranes easily. Due to the fact that they are repelled by the hydrophobic interior of the bilayer, polar molecules do not diffuse
