Effect of controlled oxidation processes on the emission and excitation of porous silicon
… the quantum efficiency under various surface oxidation treatments. We have found that, although the overall quantum efficiency (and hence the brightness of the porous surface) can vary a lot as a function of surface conditions, the time behavior of the luminescence is only weakly affected by …

Development of quantitative techniques for the study of discharge events during plasma electrolytic oxidation processes
Plasma electrolytic oxidation, or PEO, is a surface modification process for the production of ceramic oxide coatings upon substrates of metals such as aluminium, magnesium and titanium. Two methodologies for the quantitative study of electrical breakdown (discharge) events observed during plasma …

Understanding the impact of the scavenging capacity on costs of the UV chlorine advanced oxidation process for drinking water treatment using the external calibration method and the development of cost curves.
UV-driven advanced oxidation processes (e.g. UV/H2O2, UV/Cl) that couple UV irradiation with oxidizing chemicals to generate highly reactive species such as ·OH radicals and reactive chlorine species are increasingly being recommended for the removal of recalcitrant organic contaminants in drinking …

Applications of microwave technology to wastewater treatment
A microwave enhanced advanced oxidation process using hydrogen peroxide (MW/H₂O₂-AOP) was used for the release of nutrients and the destruction of solids from secondary municipal sewage sludge. The significant factors affecting the MW/H₂O₂-AOP that would yield maximum soluble substrates were …
