The thermal degradation of poly(ditetrahydrofurfuryl itaconate)
(Elsevier, Amsterdam, 2001)
The goal of this investigation was to study the thermal degradation of poly(ditetrahydro-furfuryl itaconate) (PDTHFI) by thermogravimetry (TG). The monomer was polymerized in bulk at 40 degreesC using AIBN as initiator. ...
Influence of microstructure and phase composition on the nanoindentation characterization of bioceramic materials based on hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2009)
The aim of the study was to investigate the influence of microstructure and phase composition on the mechanical behaviour of hydroxyapatite (HAp) and biphasic HAp/beta-tricalcium phosphate (beta-TCP) bioceramic materials ...
Fast estimation of quasi-steady states of cyclic nonlinear processes based on higher-order frequency response functions. Case study: Cyclic operation of an adsorption column
(Amer Chemical Soc, Washington, 2006)
A new method for fast approximate calculation of quasi-steady states of cyclic processes is presented. The method is based on the concept of higher-order frequency response functions. The system input is represented in the ...
Electrochemical polymerization and initial corrosion properties of polyaniline-benzoate film on aluminum
(Elsevier Science Sa, Lausanne, 2009)
Electrochemical synthesis of polyaniline (PANI) on aluminum electrode from aqueous Solution Of 0.25 mol dm(-3) aniline and 0.2 mol dm(-3) sodium benzoate has been investigated under potentiodynamic and galvanostatic ...
EXAFS and XANES study of the incorporation of Mn cations into a chabazite-like AlPO molecular sieve
(Int Union Crystallography, Chester, 1999)
The incorporation of Mn(II) cations into a chabazite-like MnAlPO material is studied with Mn K-edge XANES and EXAFS. Both methods show that Mn(II) is inserted exclusively into the tetrahedrally coordinated aluminum sites. ...
Insight in the regioselective enzymatic transgalactosylation of salicin catalyzed by beta-galactosidase from Aspergillus oryzae
(Elsevier Sci Ltd, Oxford, 2015)
In this study, enzymatic synthesis of galactoside of salicin, compound with potential physiological activity due to structural resemblance with galectin inhibitors, and analgesic and antipyretic properties of salicin, was ...
Study on the formation of an amoxicillin adduct with methanol using electrospray ion trap tandem mass spectrometry
(Wiley, Hoboken, 2008)
The possibility of using the protonated methanol-adduct of antimicrobial amoxicillin for its identification and quantification at residue levels has been investigated, since it is impossible to completely suppress the ...
Poly(acrylamide-co-itaconic acid) and semi-IPNS with poly(ethylene glycol): Preparation and characterization
(Wiley-VCH Verlag Gmbh, Weinheim, 2004)
A pH-responsive poly(acrylamide-co-itaconic acid) (PAAm/IA) hydrogel and semi-interpenetrating networks (semi-IPNs) with 5, 10 and 15 wt.-% of poly(ethylene glycol) (PAAm/IA/PEG), were synthesized. Their swelling behavior ...
Behavior of silicon carbide/cordierite composite material after cyclic thermal shock
(Elsevier Sci Ltd, Oxford, 2009)
In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 ...
Assessing the potential of para-donor and para-acceptor substituted 5-benzylidenebarbituric acid derivatives as push-pull electronic systems: Experimental and quantum chemical study
(Spectrochimica Acta Part A-Molecular and Biomolecular Spectroscopy, 2021)
Electronic interactions in donor-pi-linker-acceptor systems with barbituric acid as an electron acceptor and possible electron donor were investigated to screen promising candidates with a push-pull character based on ...
