Nano particles, such as aluminum powder, quartz and multiwalled carbon nanotubes were added to aniline prior to its polymerization." Glass transition temperature depended on whether nucleating agent was present or not." Addition of nucleating particles also decreased degradation rate to various degrees depending on the particle size and its specific surface area." ... 

Micro and nano-particles nsed for oral administration of drugs are solvent cast using water or organic solvents. The stirring rate and temperature under which the particles are processed greatly affects their dmg release rate and degradation properties. 

Xenobiotics are chemical compounds identified in organisms that do not normally produce or require them. In most cases the term "xenobiotic" is referred to pollutants and to their effect on biological systems, where they are considered as antigenic substances. Examples of xenobiotics are mercuric chloride, platinum salts, and silica (nano)particles, but xenobiotics are also antibiotics and many other substances produced by humans that are incorporated in microorganisms and human body even if they are not part of a normal diet. The role of xenobiotics has recently been studied for its link with antigen degradation and presentation, and the consequent antigen-driven autoimmune response. ... 

However, the reaction of using palladized iron particles is not clear. TCE degradation by Pd/Fe nano-particles is assumed to follow pseudo-first-order kinetics. The pseudo-first-order decay coefficient and half life (fi/2) can be determined after plotting experimental data.

It is no surprise that a combination of different agents that cause polymer instability increases the degradation rate. For example, the presence of heavy metals (left behind catalyst or brought in with, for example, clay nano-particles) enhances photo- or thermo-oxidative degradation. Dynamic flow behavior of the polymeric nanocomposites (PNC) with either PS or PP matrix...
