Synthesis, physicochemical, and antimicrobial characteristics of novel poly(urethane-siloxane) network/silver ferrite nanocomposites
(Springer, 2022)
In situ polymerization was used to produce novel AgFeO2@PEG/polyurethane network nanocomposites (NP-PUs) with 30–60 wt% of soft poly(dimethylsiloxane) segments in polyurethane (PU), containing 1 wt% of PEG-coated AgFeO2 ...
Comparing artificial neural network algorithms for prediction of higher heating value for different types of biomass
(Springer Science and Business Media LLC, 2022)
A new set of software tools for the prediction of the higher heating values (HHV) of arbitrarily chosen biomass species is presented. A comparative qualitative and quantitative analysis of 12 algorithms for training ...
Movement and velocity of a particle in an inverse fluidized bed
(Informa UK Limited, 2022)
The movement of particles in the fluidized bed primarily determines the mixing in the bed and determines the transfer intensities that occur between the particles and the fluid. Experimental monitoring of the velocity of ...
Size-strain line-broadening analysis of anatase/brookite (TiO2)-based nanocomposites with carbon (C): XRPD and Raman spectroscopic analysis
(UK : International Union of Crystallography, 2022)
A size-strain line-broadening analysis of the XRPD patterns and Raman spectra for two anatase/brookite (TiO2)-based nanocomposites with carbon (C) was carried out and the results compared with those of a similar sample ...
Rietveld crystal structure refinement of a natural rhombohedral grossular-andradite garnet from Serbia
(Polish Geological Institute - National Research Institute, 2022)
Four macroscopically visible B–E (rim) zones, within a large natural ferric grossular garnet of Grs58–64Adr36–42Sps2 composition, are described by means of Rietveld refinements of the crystal structures in a series of six ...
Determination of lipophilicity and ionization of fentanyl and its 3‑substituted analogs by reversed-phase thin-layer chromatography
(Elsevier, 2022)
Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the piperidine ...
Indigo Carmine in a Food Dye: Spectroscopic Characterization and Determining Its Micro-Concentration through the Clock Reaction
(MDPI, 2022)
Indigo carmine is a commonly used industrial blue dye. To determine its concentration in a commercially available food dye composed of a mixture of indigo carmine and D-glucose, this paper characterizes it through (ATR, ...
Interfacial charge transfer complex between TiO2 and non-aromatic ligand squaric acid
(Elsevier, 2022)
The attachment of squaric acid, a non-aromatic molecule, to the surface of TiO2 powder induced the optical absorption of the obtained hybrid material in the visible spectral range due to the interfacial charge transfer ...
Concentration and mobility of trace elements (Li, Ba, Sr, Ag, Hg, B) and macronutrients (Ca, Mg, K) in soil-orchid system on different bedrock types
(Springer, 2022)
The mobility of chemical elements in the soil-orchid system has been poorly studied. The aim of this study is to evaluate the uptake and mobility of several trace (Li, Ba, Sr, Ag, Hg, and B) and macronutrients (Ca, Mg, and ...
Thermodynamic Properties of Caffeine in Ethylene Glycol at High Pressures and High Temperatures
(USA : American Chemical Society, 2022)
Ethylene glycol is recognized as a heat transfer fluid. To improve its performance, caffeine is added to pure ethylene glycol. The experimental measurements of densities at pressures of up to 60 MPa and in the range of ...
