“…Xerogels are dry porous gels from solegel transition of wet gels by polymerization or evaporation. In the use of ColeeCole equation for dielectric relaxation, some recent progress was made to link the steepness factor with material fundamentals and derive it from the concept of a continuous time random walk (Coffey, 2004;Ishai, Lerner, Puzenko, & Feldman, 2013).
