Studies on trimethoprim: Hydroxypropyl-β-cyclodextrin: Aggregate and complex formation
(Elsevier, 2010-11)
The present study is focused on the characterization of the interaction between trimethoprim, a dihydropteroate synthesase inhibitor, and hydroxypropyl-β-cyclodextrin (HP-β-CD) in aqueous solution and solid state. The ...
Biosorption of chromium(III) by two brown algae Macrocystis pyrifera and Undaria pinnatifida: Equilibrium and kinetic study
(Wiley VCH Verlag, 2012-02)
Two brown algae, Macrocystis pyrifera and Undaria pinnatifida, were employed to remove Cr(III) from aqueous solutions. Both seaweeds were characterized in terms of alginate yields. The alginate contents were 20 and 30% of ...
Solubility of CO2 in three cellulose-dissolving ionic liquids
(John Wiley & Sons Inc, 2020-07)
The solubility of CO2 in three cellulose-dissolving ionic liquids (1-ethyl-3-methylimidazolium diethylphosphate, [Emim][DEP], 1-allyl-3-methylimidazolium chloride, [Amim][Cl], and 1-butyl-3-methylimidazolium chloride, ...
Pressure-Induced Hexagonal to Monoclinic Phase Transition of Partially Hydrated CePO 4
(American Chemical Society, 2019-03)
We present a study of the pressure dependence of the structure of partially hydrated hexagonal CePO 4 up to 21 GPa using synchrotron powder X-ray diffraction. At a pressure of 10 GPa, a second-order structural phase ...
Effect of pressure cycling on iron: Signatures of an electronic instability and unconventional superconductivity
(American Physical Society, 2013-08)
High pressure electrical resistivity and x-ray diffraction experiments have been performed on Fe single crystals. The crystallographic investigation provides direct evidence that in the martensitic bcc → hcp transition at ...
Magnetic Fe3O4atSiO2-Pt and Fe3O4atSiO2-PtatSiO2 structures for HDN of indole
(Multidisciplinary Digital Publishing Institute, 2019-12)
The effect of a second porous SiO2 shell in the activity and selectivity of the Fe3O4atSiO2-Pt catalyst in the hydrodenitrogenation of indole is reported. The double Fe3O4atSiO2-PtatSiO2 structure was prepared by coating ...
Adsorption of the antibiotic minocycline on cerium(IV) oxide: Effect of pH, ionic strength and temperature
(Elsevier Science, 2012-07)
Adsorption of the antibiotic minocycline (MC) on cerium(IV) oxide, CeO 2, has been studied in batch experiments by performing adsorption isotherms/kinetics under different conditions of pH, supporting electrolyte concentration, ...
Design and Effects of the Cinnamic Acids Chemical Structures as Organocatalyst on the Polymerization of Benzoxazines
(MDPI, 2020-07)
This study focuses on the catalytic effect of the two geometric isomers of a cinnamic acid derivative, E and Z-forms of 3-methoxycinnamic acid (3OMeCA), analyzing the influence of their chemical structures. E and Z-3OMeCA ...
Impact of Prosopis alba exudate gum on sorption properties and physical stability of fish oil alginate beads prepared by ionic gelation
(Elsevier, 2018-06)
This study was conducted to evaluate the effect of Prosopis alba exudate gum (G) as encapsulating matrix component on water-solid interactions, physical state, oxidative damage and appearance properties of alginate-chitosan ...
Powdered grape seeds (PGS) as an alternative biosorbent to remove pharmaceutical dyes from aqueous solutions
(IWA Publishing, 2017-09)
An alternative, low-cost and efficient biosorbent, powdered grape seeds (PGS), was prepared from wastes of a wine industry, and used to remove brilliant blue (BB) and amaranth red (AR) dyes from aqueous solutions. The ...
