The mechanism and kinetics of the tungsten (vi)-oxide reduction in the vertical tube reactor
(Editura Stiintifica Fmr, Bucharest, 2012)
Presented study shows the analysis of the process of reduction of WO 3 powder with hydrogen in the vertical tube reactor, representing a new approach in comparison to the conventional methods in the horizontal tube reactor. ...
Linear free energy relationships applied to the reactivity and the C-13 NMR chemical shifts in 4-[[(substituted phenyl)imino]methyl]benzoic acids
(Elsevier Science Bv, Amsterdam, 2012)
Linear free energy relationships (LFER) were applied to the kinetic data and C-13 NMR chemical shifts in 4-[[(substituted phenyl)imino]methyl]benzoic acids. The correlation analysis for the kinetic data and substituent-induced ...
Possibility of carbon steel eafd solidification/stabilization in concrete
(Editura Stiintifica Fmr, Bucharest, 2013)
Steel scrap recycling is generally performed by direct smelting of scrap in an electric arc furnace, generating about 2% of dust per charge. Electric arc furnace dust (EAFD) is characterized as a hazardous material, due ...
Linear Free-Energy Relationships Applied to the C-13 NMR Chemical Shifts in 4-Substituted N-[1-(Pyridine-3-and-4-yl)ethylidene]anilines
(Wiley-Blackwell, Hoboken, 2014)
Two series of 4-substituted N-[1-(pyridine-3- and -4-yl)ethylidene]anilines have been synthesized using different methods of conventional and microwave-assisted synthesis, and linear free-energy relationships have been ...
In Silico Study of Chromatographic Lipophilicity Parameters of 3-(4-Substituted Benzyl)-5-Phenylhydantoins
(Combinatorial Chemistry and High Throughput Screening, 2016)
New synthesized compounds, particularly those with biological activity, are potential drug candidates. This article describes experimental studies performed to estimate lipophilicity parameters of new 3-(4-substituted ...
Sensitivity analysis of the variational model for the particulate expansion of fluidized beds
(Taylor & Francis Inc, Philadelphia, 2020)
Fluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: U-mf, epsilon(mf) and U-t. Several correlations for U-mf, ...
Analytical Model for Drift Region Voltage Drop in 4H-SiC Vertical Double Implanted Metal Oxide Semiconductor Field Effect Transistor: Effect of Anisotropy
(IOP Publishing Ltd, Bristol, 2013)
Silicon carbide (H-4-SiC as well as H-6-SiC) is known to be an anisotropic material. Among others, the transport parameters in the c-direction such as low field mobility and saturation velocity, are moderately different ...
Polypyrrole-based Enzyme Electrode with Immobilized Glucose Oxidase for Electrochemical Determination of Glucose
(Electrochemical Science Group, Beograd, 2016)
Polypyrrole enzyme electrode was formed by immobilization of glucose oxidase via glutaraldehyde into electrochemically synthesized polypyrrole on glassy carbon electrode. Electrochemical synthesis was performed in 0.5 mol ...
Challenging analytical task: analysis and monitoring of arsenic species in water
(Gheorghe Asachi Technical University of Iasi, Romania, 2014)
Analysis and monitoring of arsenic is still a challenging analytical task. Due to its complex behaviour (different forms of arsenic that can be present depending on pH and oxidation states of arsenic) as well as demanding ...
Helicobacter Pylori Eradication Therapy is Not Associated with the Onset of Inflammatory Bowel Diseases. A Case-Control Study
(Medical Univ Press, Cluj-Napoca, 2018)
Background & Aims: A negative association between H. pylori and inflammatory bowel disease (IBD) has been previously reported. There were also case reports suggesting a new onset of IBD 6-12 months after H. pylori eradication ...
