Gum arabic microcapsules as protectors of the photoinduced degradation of riboflavin in whole milk
(American Dairy Science Association, 2014-06)
Microcapsules (MC) made with gum arabic (GA) as shell material without and with b-carotene (bc) as core material were prepared by the spray-drying technique. The effect of these MC on the photodegradation of riboflavin ...
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 ...
Multifactorial optimization of the decolorisation parameters of wastewaters resulting from dyeing flowers.
(IWA PUBLISHING, 2009-01-01)
This work deals with the treatment of the wastewaters resulting from the process of dyeing flowers. In some local cases for growing flowers near to Medellin (Colombia), wastewater color was found to be one of the main ...
