Silica gel has also been studied as a porosity-increasing additive [5]. The addition of 0.2wt.% resulted in improved capacity at both low and high rates. Although the addition of silica gel was not observed to cause significant physiochemical changes to the positive active-material, it is possible that silica gel promotes nucleation which consequently leads to a finer pore structure in the active material. Since this form of silica is porous, the additive may act as an acid reservoir. Further study of silica gel as an additive, especially at high discharge rates, has been recommended [6]. 

Physiochemical changes in enzyme structure, thermal denaturation and microbial contamination cause enzyme activity to continuously decrease with time. When enzymes or cells are compartmentalized in UF cells, biocatalyst losses can even occur due to the wrong choice of membrane molecular weight cut-off. It is conventional to measure the enzyme stability in terms of its half-life, tvs, that is the time at which enzyme activity is reduced to half its initial... 

During cellular signal transduction, proteins continuously sense various membrane compartments and associate with specific proteins or lipids in response to localized physiochemical changes. Huorescence imaging methods have been utilized to quantify and localize protein-protein and protein-lipid associations in cells. 

Thick-film lithography refers to the processes used to make thick films of photoresist, i.e., typically thick film is used to refer to films that are 5-100 pm (p) thick, and subsequently produce relief patterns in those Alms. The photoresist is a radiation-sensitive material that is applied to a substrate surface, exposed to radiation to create a physiochemical change in the exposed regions, and washed in a developer solution to produce the desired physical relief patterns. 

Thick Resist Lithography, Fig. 1 Schematic of the basic lithography process. First, a resist fihn is coated onto the substrate of interest that may contain either films to he etched or films that can be used to deposit other materials by techniques such as plating. The resist fihn is exposed pattern-wise to radiation which results in a physiochemical change in the exposed resist that...

Polymer-based DDS control the release of an active drug from the nanoparticle or polymer gel structure by a combination of diffusion and physiochemical changes in the in vivo system. Controlled aims to achieve a supply of the active component over a longer period of time or at a specific place or time. It is an objective to increase the retention time of drugs that otherwise rapidly disappear from circulation, which...
