Photocatalytic discoloration of aqueous Malachite Green solutions by UV-illuminated TiO2 nano-particles under air and nitrogen atmospheres: Effects of counter-ions and pH
(Royal Society of Chemistry, 2011-01)
Under air atmosphere, the photocatalytic discoloration of malachite green (MG) aqueous solutions (atriphenylmethane dye) in the presence of TiO2 and UV light followed an oxidative pathway, involving an N-demethylation ...
Core–sheath nanofibrous membranes based on poly(acrylonitrile-butadiene-styrene), polyacrylonitrile, and zinc oxide nanoparticles for photoreduction of Cr(VI) ions in aqueous solutions
(John Wiley & Sons Inc, 2020-03)
This investigation addresses the design of a series of poly(acrylonitrile-butadiene-styrene)/polyacrylonitrile–zinc oxide(ABS/PAN–ZnO) membranes by coaxial electrospinning. In the first instance, an optimization of ABS and ...
Emission properties of dihydropterins in aqueous solutions
(Royal Society of Chemistry, 2011-04)
Pterins belong to a class of heterocyclic compounds present in a wide range of living systems and accumulate in the skin of patients affected by vitiligo, a depigmentation disorder. The study of the emission of 7,8-dihydropterins ...
Electrochemical synthesis of palladium nanoparticles in PVP solutions and their catalytic activity in Suzuki and Heck reactions in aqueous medium
(Royal Society of Chemistry, 2014-02)
Small palladium nanoparticles (PdNPs) with large-surface area were synthesized in aqueous media in the presence of poly(N-vinylpyrrolidone) (PVP) using a simple electrochemical method. Electroreduction of Pd(II) species ...
Early instability of MIL-125-NH2in aqueous solution and mediation of the visible photogeneration of an NADH cofactor
(Royal Society of Chemistry, 2021-05)
Metal organic frameworks (MOFs) based on titanium and carboxylic acid derivatives have been recently proposed as mediators of multiple photoinduced processes in substitution of traditional semiconductor materials. In the ...
Biosorption of silver from aqueous solutions using wine industry wastes
(Taylor & Francis, 2018-03)
The potential of wine industry wastes (grape peel, seed, and stem) as alternative biosorbents to remove Ag from aqueous media was investigated in this work. Wine industry wastes were washed, lyophilized and pulverized to ...
A model-guided determination of Δdis G2 ∞ for slightly soluble gases in water using solubility data: From the solvent's freezing point to its critical point
(Springer/Plenum Publishers, 2008-03)
There is continuing interest in the description of the solubility of nonpolar gases in water over a wide range of temperatures. On one hand, the solubility data are used in many fields of science and technology; and on the ...
Isotope effects in aqueous solvation of simple halides
(American Institute of Physics, 2018-03)
We present a path-integral-molecular-dynamics study of the thermodynamic stabilities of DOH⋯ X- and HOD⋯ X- (X = F, Cl, Br, I) coordination in aqueous solutions at ambient conditions. In agreement with experimental evidence, ...
Electrical Conductivity of Supercooled Aqueous Mixtures of Trehalose with Sodium Chloride
(American Chemical Society, 2000-11)
The viscosity and electrical conductivity of aqueous solutions of trehalose and other saccharides containing 1:1 electrolytes have been measured. The decrease in the molar conductivity of each of these electrolytes with ...
Dilatational properties of soy globulin adsorbed films at the air–water interface from acidic solutions
(Elsevier, 2005-06)
In this paper we present surface dilatational properties of soy globulins (b-conglycinin,glycinin, and reduced glycinin with 10 mM of dithiothreitol (DTT)) adsorbed on the air–water interface,as a function of adsorption ...
