Solar radiation exposure accelerates decomposition and biotic activity in surface litter but not soil in a semiarid woodland ecosystem in Patagonia, Argentina
(Springer, 2019-12)
Aims: Photodegradation of senescent plant material has been identified as an important vector of aboveground carbon (C) loss in aridland ecosystems, but the consequences for biotic activity and soil C in the field are not ...
Photodegradation routes of the herbicide bromoxynil in solution and sorbed on silica nanoparticles
(Royal Society of Chemistry, 2014)
Evaluation of the rate of abiotic and biotic degradation of oxodegradable polyethylene
(Elsevier, 2016-08)
The recent introduction of oxo-degradable additive in the Argentinean market has motivated the study of the effect of abiotic (temperature and ultraviolet (UV) radiation) and biotic (aerobic in compost) degradation on the ...
Effect of Silver Addition on the Structure and Methylene Blue Photodagradation Capacity of Titania Synthesised via a Surfactant Template Route
(Asociación Química Argentina, 2010-12)
Mesoporous titania was synthesized by a surfactant template route and was doped with Ag2O by treatment with AgNO3. Commercial anatase was also used as reference material. The obtained materials were characterized by nitrogen ...
Photochemistry of tyrosine dimer: when an oxidative lesion of proteins is able to photoinduce further damage
(Royal Society of Chemistry, 2019-04)
The tyrosine dimer (Tyr2), a covalent bond between two tyrosines (Tyr), is one of the most important modifications of the oxidative damage of proteins. This compound is increasingly used as a marker of aging, stress and ...
Oxidation of ophthalmic drugs photopromoted by inorganic radicals
(Elsevier Science SA, 2012-09)
The rate constants of the reactions of the sulfate (SO4radical dot−) and hydrogen phosphate (HPO4radical dot−) radicals with the imidazoline derivatives naphazoline, tetrahydrozoline, oxymetazoline, xylometazoline, and the ...
On the natural fate of maleic hydrazide. Kinetic aspects of the photochemical and microbiological degradation of the herbicide
(Elsevier Science Sa, 2014-04)
Kinetic and mechanistic aspects of the photochemical and microbiological degradation of the herbicide Maleic Hydrazide (MH) have been studied. Riboflavin (Rf, vitamin B2) was employed as a main photosensitizer whereas Humic ...
UV-C radiation effect on nuclear tracks of different ions in polycarbonate
(Pergamon-Elsevier Science Ltd, 2020-08)
The neutron autoradiography technique was developed in our laboratory using polycarbonate nuclear track detectors, to qualitatively and quantitatively analyze boron distribution and concentration in biological samples from ...
Reactive dyes remotion by porous TiO2-chitosan materials
(Elsevier Science, 2008-04)
In this work, the aim was to evaluate the remotion (adsorption plus degradation) of two reactive dyes, Methylene Blue (MB) and Benzopurpurin (BP), from aqueous solutions by the utilization of TiO2-chitosan microporous ...
Influence of TIO2-rGO optical properties on the photocatalytic activity and efficiency to photodegrade an emerging pollutant
(Elsevier Science, 2019-06)
TiO 2 -reduced graphene oxide (TiO 2 -rGO) photocatalysts with different mass ratios (GO:TiO 2 0.1-0.5-1%) were synthesized via a hydrothermal method and compared through their physico-chemical properties and photocatalytic ...
