Gibbs’ Paradox is shown to arise from an incorrect traditional definition of the entropy that has unfortunately become entrenched in physics textbooks. Among its flaws, the traditional definition predicts a violation of the second law of thermodynamics when applied to colloids. By adopting Boltzmann’s definition of the entropy, the violation of the second law is eliminated, the properties of co...

During the organ transplantation process, conservation solutions must address responses to the physiologic organ preservation and prevent ischemia-reperfusion injuries. The use of colloids seems beneficial especially for long ischemia time compared to the impermeant molecules used for short time. The colloids family includes molecules as hydroxyethyl starch (HES), albumin, dextran or polyethyle...

Colloidal crystallization has been explored for several years as a fabrication method for photonic crystals. While macroporous materials grown with silica or polymer colloids might exhibit pleasing opalescence, truly novel photonic behavior such as photonic band-gaps, is expected only for very high index of refraction contrast systems. This can possibly be achieved through electrodeposition of ...
