Oxalic Acid as a Sacrificial Agent in the Photoreduction of Water Contaminants
(Nova Science Publishers, 2012)
Oxalic acid (OA) as a sacrificial agent (hole scavenger) in the photoreduction of Cr(VI), was evaluated in a radiation efficient photocatalytic fluidized bed (FB) of a TiO2-quartz sand catalyst composite vis à-vis the ...
Silicate Ions as Corrosion Inhibitors for Carbon Steel in Chloride-Contaminated Concrete Pore Simulating Solutions
(NACE International, 2020-10)
Silicate ions were tested as corrosion inhibitors for construction steel using concrete pore simulating solutions contaminated with chloride ions. The results are compared to those from solutions with no silicate and with ...

Disinfection protocols to prevent cross-contamination between dental offices and prosthetic laboratories
(2013)
Control of cross-contamination between dental offices and prosthetic laboratories is of utmost importance to maintain the health of patients and dental office staff. The purpose of this study was to evaluate disinfection ...
Electronic nose: A useful tool for monitoring environmental contamination
(Elsevier Science Sa, 2000-10)
The advances in the technology of multisensor arrays and neural computation have allowed the development of 'electronic noses', which has enabled the discrimination of compounds by their odours and consequently, has played ...
Spin contamination in XOO radicals X = F, Cl, Br, HO: How is the investigation of the HOOO radical affected
(ELSEVIER SCIENCE BV, 2008)
We have analysed the effect of spin contamination in the wavefunction of HOOO. At least, two solutions can be found for the HF wavefunction. One, lower in energy, presents a high spin contamination and gives qualitatively ...
Impact of temperature changes and pH on aqueous solutions of TCAB, a derived propanil contaminant
(Pergamon-Elsevier Science Ltd, 2019-11)
3,4,3′,4′-tetrachloroazobenzene known as TCAB is an unwanted product derivate from the degradation of propanil herbicide. In this work UV–visible and infrared spectroscopies were used to experimentally explore the impact ...
