Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
Antimicrobial Activity of Thiocarbohydrazones: Experimental Studies and Alignment-Independent 3D QSAR Models
(Wiley-VCH Verlag Gmbh, Weinheim, 2018)
Due to the rise of microbial strains resistant to conventional therapies, there is an urgent need for finding the new antimicrobial chemotypes. Heterocyclic compounds such as thiocarbohydrazones (TCHs) are able to interact ...
Improvement of the Textile Industry Wastewater Decolorization Process Using Capillary Microreactor Technology
(Springer International Publishing Ag, Cham, 2019)
Dyes are an important class of pollutants because large amounts are often found in the environment as a result of their extensive industrial use. Traditional wastewater treatment methods often lead to high energy costs, ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNaH(2)PO(4)+(1-y)KH2PO4}(aq) System at T=298.15K
(Springer/Plenum Publishers, New York, 2019)
Isopiestic measurements have been made for aqueous mixtures of NaH2PO4 and KH2PO4 at T=(298.15 +/- 0.01) K, at NaH2PO4 ionic strength fractions y=(0, 0.19108, 0.38306, 0.58192, and 1), assuming that both electrolytes ...
Antibacterial activity of metal-containing clinoptilolite in natural seawater
(Desalination Publ, Hopkinton, 2019)
Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol of Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains of Gram-negative bacteria - Escherichia coli and Acinetobacter ...
Structurally and surface-modified alumina particles as a reinforcement in polyester-based composites with an improved toughness
(Springer, New York, 2020)
Commercial gamma - Al2O3 particles, Al2O3 n, and synthesized Al2O3 doped with iron oxide (Al2O3 Fe) were used as reinforcements to enhance the toughness of an unsaturated polyester resin (UPR). Alumina modification with ...
Modelling, simulation and optimisation of pulse-reverse regime of copper, silver and gold electrodeposition
(Carl Hanser Verlag, 2018)
Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, ...
Electrochemical decolorization of CI Acid Orange 3 in the presence of sodium chloride at iridium oxide electrode
(Springer International Publishing Ag, Cham, 2017)
The electrocatalytic degradation of C.I. Acid Orange 3 from simulated wastewater by indirect electrochemical oxidation using an IrOx electrode was investigated. The effects of different operating parameters on the rate of ...
Quantitative Structure-Retention Relationships Modeling and Multivariate Data Analysis of Lipophilicity Data of New Spirohydantoin Derivatives
(Akademiai Kiado Zrt, Budapest, 2016)
Modeling properties of newly synthesized compounds is important for both understanding their activity and predicting their interactions. This paper describes the evaluation of the lipophilicity of the newly synthesized ...
Influence of surface modification to mechanical and thermal properties of nanomodified acrylic dental resin
(Inst Materials Physics, Bucharest, 2018)
This paper investigated the processing and characterization of dental nanocomposites based on poly(methyl methacrylate) (PMMA) matrix reinforced with zirconium dioxide (ZrO2) nanoparticles were prepared by in-situ free ...
