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, ...
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 ...
Oxidized pentacene micro-rods obtained by thermal annealing of pentacene thin films in air
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Prolonged annealing of pentacene thin films in air leads to the formation of nano- and micro-scale rod-shaped structures at temperatures equal to or higher than 130 degrees C. Scanning electron microscopy measurements ...
Structural Properties of the Multiwall Carbon Nanotubes/Poly(Methyl Methacrylate) Nanocomposites: Effect of the Multiwall Carbon Nanotubes Covalent Functionalization
(Wiley, Hoboken, 2017)
The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. ...
A facile route for hydroxyapatite densification with an increased heating rate
(Elsevier Science Bv, Amsterdam, 2017)
The densification behavior of hydroxyapatite nanorods prepared by chemical precipitation method in open reactor conditions was investigated by application of different heating rates. The non-isothermal processing was ...
Microencapsulation of anthocyanin-rich black soybean coat extract by spray drying using maltodextrin, gum Arabic and skimmed milk powder
(Taylor & Francis Ltd, Abingdon, 2017)
Black soybean coat is insufficiently valorised food production waste rich in anthocyanins. The goal of the study was to examine physicochemical properties of spray dried extract of black soybean coat in regard to carrier ...
Nanoscale zerovalent iron (nZVI) supported by natural and acid-activated sepiolites: the effect of the nZVI/support ratio on the composite properties and Cd2+ adsorption
(Springer Heidelberg, Heidelberg, 2017)
Natural (SEP) and partially acid-activated (AAS) sepiolites were used to prepare composites with nanoscale zerovalent iron (nZVI) at different (SEP or AAS)/nZVI ratios in order to achieve the best nZVI dispersibility and ...
Preliminary investigation on the use of the Q-switched Nd:YAG laser to clean corrosion products on museum embroidered textiles with metallic yarns
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2017)
The classic methods of cleaning old-fashioned textile museum objects with metallic yarns do not often yield expected results. The use of laser in the conservation of these objects plays an important role as a very efficient ...
Chemometric evaluation of binary mixtures of alginate and polysaccharide biopolymers as carriers for microencapsulation of green tea polyphenols
(Taylor & Francis Inc, Philadelphia, 2017)
In this study principal component analysis and artificial neural networks were used to evaluate the potential of using binary mixtures of sodium alginate and other polysaccharide biopolymers as the carriers for microencapsulation ...
Structural, thermal, mechanical, swelling, drug release, antibacterial and cytotoxic properties of P(HEMA)/PVP semi-IPN hydrogels
(Inst Chemical Engineers, Rugby, 2017)
The aim of this work was to synthesize a series of semi-interpenetrating polymer networks (semi-IPNs) of 2-hydroxyethyl acrylate and itaconic acid, in the presence of poly(N-vinylpyrrolidone). Samples were synthesized by ...
