Design of highly polarized achiral mesogenic composites
(2012)
The synthesis of one homologous series of methacrylate monomers and their polymers was carried out to observe the dependence between the polarization and some structural aliphatic features. Investigations of the thermoanalytical, ...
Remote regio- and stereocontrol by the sulfinyl group: Diels-Alder reaction of sulfinyl dienols and 8,8-dimethylnaphthalene-1,4,5(8H)-trione
(2013)
Diels-Alder cycloaddition of 8,8-dimethylnaphthalene-1,4,5(8H)-trione with diastereomeric hydroxysulfinyldienes proceeded with high yields and good π-facial and regioselectivities. The hydroxysulfoxide moiety controls the ...
RP-HPLC×HILIC chromatography for quantifying ertapenem sodium with a look at green chemistry
(2016-11-01)
Ertapenem sodium is a polar and ionizable compound; therefore, it has little retention on traditional C18 columns in reverse-phase high-performance liquid chromatography, even using a highly-aqueous mobile phase that can ...
Flow chemistry to control the synthesis of nano and microparticles for biomedical applications
(Bentham Science Publishers B.V., 2014)
In this article we review the flow chemistry methodologies for the controlled synthesis of different kind of nano and microparticles for biomedical applications. Injection mechanism has emerged as new alternative for the ...
Solvent-less method for efficient photocatalytic α-Fe2O3 nanoparticles using macromolecular polymeric precursors
(Royal Society of Chemistry, 2016)
© 2016 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique. We report a method for solvent-less growth of single crystalline hematite Fe2O3 nanoparticles from metal-containing polymeric ...

Polarographic behaviour and determination of ranitidine in pharmaceutical formulations and urine
(1994)
A polarographic method for the determination of ranitidine is described, based on the reduction of the nitro group at a dropping-mercury electrode. The proposed method permits the drug to be determined, without any prior ...
Synthesis of polymeric organic-inorganic hybrid materials. Partially deacetylated chitin-silica hybrid
(Wiley-VCH Verlag, 1997)
This work reports the synthesis of a novel polymeric organic-inorganic hybrid. The inorganic component is a silica network obtained by controlled hydrolysis of tetraethyl orthosilicate via sol-gel process and the organic ...
Rate Constants for Reactions in Viscous Media: Correlation between the Viscosity of the Solvent and the Rate Constant of the Diffusion-Controlled Reactions
(1988)
The kinetics of the quenching of excited pyrene by several molecules in a variety of hydrocarbon solvents and in a diol are reported. The rate constants for reaction of the excited pyrene are, for the most part, ...
