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 ...
Improved Oxygen Reduction on GC-Supported Large-Sized Pt Nanoparticles by the Addition of Pd
(Švajcarska : MDPI, 2022)
PdPt bimetallic nanoparticles on carbon-based supports functioning as advanced electrode materials have attracted attention due to their low content of noble metals and high catalytic activity for fuel cell reactions. ...
Thermal analysis and phase changes of mechanochemically activated sodium carbonate
(Elsevier, 2022)
Sodium carbonate is a well-known material for being used as a good sorbent of carbon dioxide from the atmosphere, and as such has gained increasing importance in environmental protection. In order to enhance its sorption ...
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 ...
Structural, Mechanical and Electrical Characteristics of Copper Coatings Obtained by Various Electrodeposition Processes
(MDPI, 2022)
Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current ...
PtAu Nanoparticles Supported by Reduced Graphene Oxide as a Highly Active Catalyst for Hydrogen Evolution
(Catalysis, 2022)
PtAu nanoparticles spontaneously deposited on graphene support, PtAu/rGO, have shown
remarkably high catalytic activity for hydrogen evolution reaction (HER) in sulfuric acid solution.
SEM images of the PtAu/rGO electrode ...
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 ...
The development of a process simulator transport model for RO systems
(Elsevier, 2022)
This paper introduces solute-solvent interactions onto a universal transport modeling approach that has been recently introduced for predicting RO membrane performance. The mathematical modeling framework utilizes chemical ...
Inhibitory effect of cysteine and lanthanides on AA7075‐T6 in neutral NaCl solution
(Weinheim, Germany : Wiley‐VCH GmbH., 2022)
The inhibitory effect of cysteine in the presence of selected lanthanide chlorides (LaCl3, NdCl3, and CeCl3) in a neutral 0.1M NaCl solution was analyzed. The cysteine concentration of 0.3mMwas determined as an optimal ...
