However, because polymer in coating are susceptible to degradation [...]

The distribution of engineered nanoparticles (ENPs) in municipal wastewater treatment systems

Choi S., Eichhorn J., Johnston M., Huang C.P., University of Delaware, US

The objective of this research was to develop a method reliable for the detection and quantification of engineered nanoparticles in municipal wastewater treatment systems. Wastewater and sludge samples were sampled from four regional municipal wastewater [...]

An analytical method to quantify the release of silica nanoparticles from polymer nanocomposites exposed to UV radiation

Rabb S.A., Yu L.L., Nguyen T., National Institute of Standards and Technology, US

Silica nanoparticles are being utilized to enhance the mechanical performance of polymeric coatings used in automotive and construction industries. However, cumulative effects of UV radiation will degrade the polymeric molecules, resulting in a potential for [...]

Slurry sample injection for determination of ferrite nanocolloids chemical composition by ICP spectrometry

Sousa M.H., Lins E.S., Tourinho F.A., Depeyrot J., Martins W.D., Zara L.F., Castro C.F.S., de Castro G.R., Universidade de Brasilia, BR

In the biomedical field, some applications of nanomaterials require dynamically quantifying them in blood and tissues probes. Nevertheless, the usual methods which are employed to titrate the nanoparticles require their dissolution before the chemical analysis, [...]
