In the present work, the Ni-V system was thermodynamically modelled using the Calphad approach. In the modelling, experimental data on mixing and formation enthalpies, and phase boundaries as well as first-principles data were included. Thermodynamic properties of stable phases of the modelled N...

The kinetics of V(V) extraction from acidic sulfate medium by primary amine N1923(RNH2) dissolved in sulfonated kerosene has been investigated using a falling single drop technique. The time of drop formation and coalescence was determined and considered for calculating the V(V) transfer flux. T...

V&V constitutes a powerful framework to demonstrate the capability of computational tools in several technological areas. Passing V&V requirements is a needed step before applications. Let's focus hereafter to the area of (transient) Nuclear Thermal-hydraulic (NTH) and let's identify V...

We studied the effect of inhibitors of methylation (p-aminosalicylic acid, sulfonamides, aminopterine) on the biosynthesis of the oligoketide antibiotics, monensins A and B, and their cometabolites, 3-O-demethylmonensins A and B. The inhibitors were supplied to the culture medium of Streptomyces...

Two transient species have been detected in the photoenolization of 2-methylbenzophenone by time-resolved resonance Raman spectroscopy. The shorter-lived species characterized by bands at 1522 and 1275 cm−1 is attributed to the cis dienol based on the vibrational assignments of these bands, the ...

The phosphorescence decays of benzophenone, 2-methylbenzophenone (OMBP), 3-methylbenzophenone, 4-methylbenzophenone (PMBP), and deuterated analogues of the ortho and para derivatives have been observed at 77 K in ether-pentane-alcohol glasses. The decays were fitted to gaussian distributions of ...

Various electrochemical methods have been applied to establish the electrochemical characteristics of the electrical double layer capacitor (EDLC) consisting of the 1 M triethylmethylammonium tetrafluoroborate solution in acetonitrile and activated carbon based electrodes. Activated microporous ...

Polychlorinated biphenyls (PCBs), dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) binding with the aryl hydrocarbon receptor (AhR) have been correlated with many toxic responses. Hence, it is very necessary to study the interactions between these ligands and AhR for further understanding of ...

There is concern about the growing environmental levels of brominated dioxins. Brominated dioxins are known to bind and activate the transcription factor aryl hydrocarbon receptor (AhR), as their chlorinated congeners do. However, data on the potency of brominated dioxins for immunotoxicity in v...

SummaryObjectivesTo evaluate the effect of photo-irradiation time to the adhesive on the regional bond strength of a dual-cure resin core material to root canal dentine using photo and dual-cure adhesives with self-etching primer.

PurposeTo evaluate the shear bond strengths of two gingiva-colored materials (an indirect composite material and a denture base acrylic resin) to zirconia ceramics and determine the effects of surface treatment with various priming agents.

BackgroundAs a mechanism for assessing continuing competence, many regulatory jurisdictions have implemented continuing competence frameworks, using a variety of competence assessment indicators. It is argued that a well-developed competence framework provides assurance to the regulator and the ...

New fluoroalkylated 2-(methacryloxy ) ethane sulfonic acid homo-oligomers were prepared in excellent to moderate yields by the reactions of fluoroalkanoyl peroxides with 2-(methacryloxy) ethane sulfonic acid (MES) under very mild conditions. These fluoroalkylated oligomers were easily soluble no...

In the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(0), chlorodisilanes of type MenSi2Cl6−n (n = 2–5) add to acetylene to afford 1,2-bis(chlorosilyl)ethenes in reasonable yields.

In order to determine the importance of the two ester pharmacophores in high affinity, conformationally constrained DAG-lactones (Lac-1–5) as PK-C ligands, we have independently replaced the sn-1 and sn-2 carbonyl esters in these compounds by ketone (2, 10, 11), amide (3, 25–28), and hydroxyl ...

Deoxycholic acid derivatives were designed as P-glycoprotein (Pgp, ABCB1) inhibitors. Thus the synthesis and the biological activity of methyl deoxycholate derivatives 5–10 and their ether analogs 15–20 have been reported. The potency of these compounds to modulate Pgp-mediated MDR was evaluat...

N,N′-Bis(chlorodimethylsilyl)tetramethylcyclodisilazane, which is obtained along with minor proportions of 1,3-dichloro-1,1,3,3-tetramethyldisilazane, 1,5-dichloro-1,1,3,3,5,5-hexamethyltrisilazane, and N-(chlorodimethylsilyl)-N′-(3-chloro-1,1,3,3-tetramethyldisilazanyl)tetramethylcyclodisilaz...

Mg-promoted reductive coupling of aromatic carbonyl compounds (1) with chlorosilanes, such as trimethylsilyl chloride (TMSCl:2), 1,2-bis(chlorodimethylsilyl)ethane (3) and 1,5-dichlorohexamethyltrisiloxane (4), in N,N-dimethylformamide (DMF) at room temperature brought about selective and facile...

Structural and electronic properties of vacancy, water and ethylenediamine substitutions in nitromethane were calculated using the first-principles density-functional theory. The results indicate both vacancy and substitution decrease the band gaps, which suggests the sensitivity of nitromethane...

The pyrolysis and oxidation of nitromethane (NM) were studied in a plug flow reactor over the temperature range of 735–1476 K at 5 Torr and in a jet-stirred reactor over the temperature range of 600–875 K at atmospheric pressure, respectively. Mole fraction profiles of major products and inter...
