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 ...
Spontaneous Symmetry Breaking: The Case of Crazy Clock and Beyond
(MDPI AG, 2022)
In this work, we describe the crazy-clock phenomenon involving the state I (low iodide and iodine concentration) to state II (high iodide and iodine concentration with new iodine phase) transition after a Briggs–Rauscher ...
The HEV Ventilator: at the interface between particle physics and biomedical engineering
(The Royal Society, 2022)
A high-quality, low-cost ventilator, dubbed HEV, has been developed by the particle physics community working together with biomedical engineers and physicians around the world. The HEV design is suitable for use both in ...
Deep Eutectic Solvent (DES) for In Situ Templating Carbon Material: Carbon Characterization and Application in Supercapacitors Containing Multivalent Ions
(MDPI, 2022)
The development of carbon materials with desirable textures and new aqueous electrolytes is the key strategy to improve the performance of supercapacitors. Herein, a deep eutectic solvent (DES) was used for in situ templating ...
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 ...
Synthesis and Application of Domestic Glassy Carbon TiO2 Nanocomposite for Electrocatalytic Triclosan Detection
(MDPI AG, 2022)
Nanoparticles of TiO2 are suitable for many catalytic and photocatalytic applications due to their extraordinary properties such as superhydrophobicity, semiconductivity, electron-rich, and environmental compatibility. The ...
Influence of Al2O3 Nanoparticles Addition in ZA-27 Alloy-Based Nanocomposites and Soft Computing Prediction
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Three different and very small amounts of alumina (0.2, 0.3 and 0.5 wt. %) in two sizes
(approx. 25 and 100 nm) were used to enhance the wear characteristics of ZA-27 alloy-based nanocomposites.
Production was realised ...
Photoluminescent and Photocatalytic Properties of Eu3+-Doped MgAl Oxide Coatings Formed by Plasma Electrolytic Oxidation of AZ31 Magnesium Alloy
(MDPI, 2022)
The synthesis of Eu3+-doped MgAl oxide coatings containing MgO and MgAl2O4 was accomplished through plasma electrolytic oxidation of AZ31 magnesium alloy in aluminate electrolyte with the addition of Eu2O3 particles in ...
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 ...
