Synthesis, characterization and biological activity of 2-(5-arylidene-2,4-dioxotetrahydrothiazole-3-yl) propanoic acid derivatives
(Elsevier Science Bv, Amsterdam, 2017)
A series of six novel 2-(5-arylidene-2,4-dioxotetrahydrothiazole-3-yl) propanoic acids and six corresponding methyl esters were synthesized. All compounds were characterized by melting points, elemental analysis, FT-IR, ...
On the choice of optimal conformation in linear free-energy relationships. Reactivity of 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Rate constants for the esterification of eleven 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane in ethanol at 30 degrees C were determined, and correlated with substituent constants using ...
Titanium coated with high-performance nanocrystalline ruthenium oxide synthesized by the microwave-assisted sol-gel procedure
(Springer, New York, 2016)
Ruthenium oxide coating on titanium was prepared by the sol-gel procedure from well-defined colloidal oxide dispersions synthesized by the microwave (MW)-assisted hydrothermal route under defined temperature and pressure ...
Cloud Point Phenomena in the (Aniline or N,N-Dimethylaniline plus Water) Solutions, and Cosolvent Effects of Liquid Poly(ethylene glycol) Addition: Experimental Measurements and Modeling
(Amer Chemical Soc, Washington, 2015)
In this work, liquid phase behavior (cloud point phenomena) was studied for two binary and four aqueous pseudobinary systems containing aniline or N,N-dimethylaniline and poly(ethylene glycol) 200 Or poly(ethylene glycol) ...
In Vivo Performance of Fenofibrate Formulated With Ordered Mesoporous Silica Versus 2-Marketed Formulations: A Comparative Bioavailability Study in Beagle Dogs
(Wiley-Blackwell, Hoboken, 2016)
The present study aims to evaluate the in vitro and in vivo performance of ordered mesoporous silica (OMS) as a carrier for the poorly water-soluble compound fenofibrate. Fenofibrate was loaded into OMS via incipient wetness ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Conservation of resources in the pulp and paper industry derived from cleaner production approach
(Resources Conservation and Recycling, 2011)
This paper analyses the utilization of water and recycled fiber from waste paper for the production in one Serbian cardboard mill. Water and fiber consumption, wastewater generation and its characteristics, as well as ...
Diffusion and solubility of commercial poly(methyl methacrylate) denture base material modified with dimethyl itaconate and di-n-butyl itaconate during water absorption/desorption cycles
(Wiley-Blackwell, Hoboken, 2012)
This study evaluated the water absorption, solubility, kinetics of water diffusion and residual monomer content of commercial poly(methyl methacrylate) (PMMA) denture base material modified with dimethyl itaconate (DMI) ...
The Role of SnO2 on Electrocatalytic Activity of PtSn Catalysts
(Springer, New York, 2018)
In our previous paper, we described in detail studies of Sn influence on electrocatalytic activity of PtSn catalyst for CO and formic acid oxidation (StevanoviAc et al., J. Phys. Chem. C, 118 (2014) 278-289). The catalyst ...
Synthesis, structure, and solvatochromic properties of pharmacologically active 5-substituted 5-phenylhydantoins
(Springer Wien, Wien, 2011)
A series of 5-substituted 5-phenylhydantoins was synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability ...
