Many people believe that slabs on ground typically should have some reinforcing, but most slabs in North America are unreinforced concrete and perform well. If reinforcing is utilized, the amount that should be used depends on what is to be accomplished.
Micelles are lipid molecules that arrange themselves in a spherical form in aqueous solutions. The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic regions (polar head groups) as well as hydrophobic regions (the long hydrophobic chain). Micelles contain polar head groups that usually form the outside as the surface of micelles.
Micelle. Micelles are aggregates of surfactants in a liquid medium which are formed when the surfactant concentration exceeds the critical micelle concentration(CMC).he term micelle should designate any soluble aggregate spontaneously and reversibly formed from amphiphilic molecules or ions. As the concentration of aqueous solutions of many amphiphilic substance increases, there is a pronounced change in the physical properties of the solution.
