The solubility of esomeprazole magnesium trihydrate in methanol, ethanol, 1-propanol and 1-butanol was determined at temperatures ranging from 298.15 to 318.15 K at atmospheric pressure using gravimetrical method. The highest solubility is found in 1-butanol and lowest in ethanol. The experimental solubility data are…
In this study, we propose binary mask (BIM) designs with single- and double-layer absorber stacks with high optical contrast at a wavelength of 13.5 nm for use in extreme ultraviolet lithography (EUVL) and actinic defect inspection. The optimum thickness of the absorber stack was estimated using a method based on the…
In the salt solubility predictions for K+-Na+-Mg 4 2− aqueous solution the treatment of thermodynamic data of three-component systems at T = 298.15 K involved the application of the Extended Pitzer’s ion-interaction model for the pure and mixed electrolyte solutions and criteria of phase equilibrium. Osmotic coefficie…
Abstract Carbon dioxide is a greenhouse gas and substantially affects the global warming and climate change, so study on the adsorption of carbon dioxide is very urgent. As a new CO 2 captor, Ba 2 Fe 2 O 5 was prepared by the solid state reaction of Fe 2 O 3 with BaCO 3 , following formula Fe 2 O 3 + 2BaCO 3 = Ba 2 Fe…
Bifunctional mesoporous silicas with clearly distinguished localization of grafted groups on the surface of particles and inside their pores were obtained by means of sol-gel synthesis with postsynthetic vapor-phase treatment in vacuum. It was found that the synthesized materials have the hexagonally ordered porous st…
This paper describes the rheological and thermal behaviour of alkylated chitosan and hyaluronan derivatives and methylcellulose, Their behaviour is characterized by the formation of hydrophobic domains which may be considered as crosslinked points. Then, depending on the thermodynamic conditions (temperature, salt con…
A Myxococcus xanthus DspA contains 12 subdomains characteristic of eukaryotic-like protein kinases but with an atypical sequence, RDxSPHN, in the catalytic loop, different from the consensus motifs observed in Ser/Thr kinases (RDxKxxN) or Tyr kinases (RDx(A/R)A(A/R)N). DspA phosphorylated myelin basic protein (MBP) on…
In this paper, we propose an in-plane beam splitter for self-collimated beams in a two-dimensional photonic crystal. An optical filter inserted on the propagation path of the input self-collimated beam divides this beam into two parallel equi-power self-collimated beams. The optical filter has a multistage configurati…
The technological impact of porous structures in catalytic applications has stepped up the search for innovative shaping tools. A new approach to shape porous structures based on the assembly of hybrid micelles under the influence of a directional driving force, such as the electric field, is proposed in this work. Th…
We have used molecular dynamics (MD) simulations to study phase-separation kinetics in a binary fluid mixture (AB) confined in an antisymmetric thin film. One surface of the film (located at z = 0) attracts the A-atoms, and the other surface (located at z = D) attracts the B-atoms. We study the kinetic processes which…
The issues of dissolution, agglomeration, CO poisoning and high cost associated with the use of Pt electrode for fuel cells have been driving the search for alternative electrocatalysts with better technical and economic performances. In this study, we report the synthesis of alternative macroporous Pd and La2O3 incor…
Palladium Pd/polyaniline (PANI) nanocomposite was prepared by a thermal reflux method as the catalyst for direct ethanol fuel cells. The Pd/PANI catalysts were characterized by using FTIR transmission electron microscopy techniques. The electrocatalytic performances of Pd/PANI catalysts for ethanol oxidation were stud…
We theoretically study the quasiparticle resonance states around a nonmagnetic impurity in cuprate superconductors based on t-t'-J-U model. The purpose of introducing the Coulomb repulsive interaction U is to partially impose the double occupancy constraint by employing the Gutzwiller projected mean-field approximatio…
The present work investigated corrosion behaviour of J55 tubing steels and solution equilibrium chemistry of the produced water under simulated CO2 flooding environments at various temperatures. The corrosion rates were calculated by weight loss method carried out with or without one kind of imidazoline based inhibito…
The quantitative differentiation of liposomal encapsulated and non-encapsulated drug tissue concentrations is desirable, since the efficacy and toxicity are only related to the level of non-encapsulated drug. However, such separate concentration profiles in tissues have still not been reported due to lacking analytica…
The atmospheric microplasma metal organic chemical vapor deposition (AP-MOCVD) using titanium (IV) tetraisopropoxide (TTIP) as a metal alkoxide titanium source was investigated for depositing TiC and TiN hard coatings on stainless steel rods for improving the tool life of electroplated diamond tools. The components an…
Solving the time-dependent Bogoliubov–de Gennes equations, we calculate current–voltage characteristics (CVC) and conductances (G) of clean d-wave superconductor/ferromagnet/d-wave superconductor (DFD) junctions with transparent D/F interfaces. Due to the suppression of Andreev reflection (AR) by the exchange energy \…
Abstract We report that a nanoporous Au film capped with a dielectric surface layer enables the effective absorption of near‐infrared light and intense emission of two‐photon luminescence. In this approach, nanoscale pores in Au are incorporated by chemical dissolution and microscale surface patterns are added on the…
In the present study commercial available chromium based hardfacing alloy (CPET 071) was deposited on SS304 steel by manual metal arc welding process to investigate the erosion behaviour. Solid particle erosion study was carried out using air jet erosion tester rig. Erosion testing was done at room and 400°C temperatu…
Submerged arc welding (SAW) is a process in which welding joint is obtained by heating the metal with an arc set between bare electrode and work piece. Intense heat produced during the process fuses the metal and filler metal. Flux is used as a shielding agent which is placed over the welding area to protect the molte…
