Synthesis and characterization of Cr3+ doped TiO2 nanometric powders
(Elsevier, 2016)
Simple route was used for synthesis of nanostructured titania samples doped with 3 and 6 mol% of Cr3+ Titanium(IV)-isopropoxide and water were used as starting materials and as an agents for controlling hydrolysis and ...
Soluplus (R), Eudragit (R), HPMC-AS foams and solid dispersions for enhancement of Carvedilol dissolution rate prepared by a supercritical CO2 process
(Elsevier Sci Ltd, Oxford, 2019)
The present work is aimed towards designing advanced materials by means of sustainable processes. In that sense, the utilization of supercritical CO2 (scCO(2)) for processing of pharmaceutical polymers (Soluplus (R), ...
The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (J(0)/J(L)) at low level of surface coarseness on the polarization characteristics of the ...
Structure and properties of thermoplastic polyurethanes based on poly(dimethylsiloxane): Assessment of biocompatibility
(Wiley-Blackwell, Hoboken, 2014)
Properties and biocompatibility of a series of thermoplastic poly(urethane-siloxane)s (TPUSs) based on alpha,omega-dihydroxy ethoxy propyl poly(dimethylsiloxane) (PDMS) for potential biomedical application were studied. ...
The electrochemical reduction of trinitrotoluene on a platinum wire modified by chemisorbed acetonitrile
(Elsevier, 2010)
The electrochemical reduction of 2,4,6-trinitrotoluene (TNT) was investigated by cyclic voltammetry on a platinum electrode in aqueous sodium chloride solutions with acetonitrile containing different concentrations of TNT. ...
Functional bioreactor characterization to assess potentials of nanocomposites based on different alginate types and silver nanoparticles for use as cartilage tissue implants
(Wiley, Hoboken, 2019)
In this work, functional characterization of biomaterials concerning potential application as articular cartilage implants was performed by using a biomimetic bioreactor with dynamic compression in the physiological regime ...
Pt supported on nano-tungsten carbide as a beneficial catalyst for the oxygen reduction reaction in alkaline solution
(Elsevier, 2012)
Platinum nanocatalyst at nano-tungsten carbide was synthesized, characterized and tested for oxygen reduction reaction (ORR) in 0.1 mol dm−3 NaOH, at 25 °C. Tungsten-carbide islands on nano-tungsten particles (WC) was ...
Effect of solution pH on crack initiation and propagation in glass-polyester pipes subjected to impact
(Wiley-Blackwell, Hoboken, 2012)
The objective of this study was the determination of the influence of alkaline and acidic solutions on the impact properties of glass-polyester composite pipes. First, the impact test was performed on virgin samples (without ...
