Revival of Hückel Aromatic (Poly)benzenoid Subunits in Triplet State Polycyclic Aromatic Hydrocarbons by Silicon Substitution
(Wiley, 2022)
By employing density functional theory (DFT)
calculations we show that mono- and disilicon substitution in
polycyclic aromatic hydrocarbons, having two to four
benzene units, quenches their triplet state antiaromaticity ...
Cerium citrate as ecologically friendly corrosion inhibitor for AA7075 alloy
(Wiley, 2022)
The corrosion behaviour of high-strength AA7075 aluminium alloy in NaCl solution, without and in the presence of environmentally friendly corrosion inhibitors (Ce-chloride and Ce-citrate) in low concentrations ( lt 0.5 ...
Analysis of the Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate as corrosion inhibitor of the aluminum alloys in NaCl solution
(Wiley, 2022)
Green corrosion inhibitors, Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate, were tested in NaCl solution with the aim to evaluate their inhibitory effect on 7049 aluminum alloy and to propose a mechanism of their ...
Cobalt(II) and magnesium(II) complexes with 1,3-pdta-type of ligands: influence of an alkyl substituent at 1,3-propanediamine chain on the structural and antimicrobial properties of the complex
(Taylor &Francis, 2022)
To investigate how modification in the structure of 1,3-propanediamine chain of 1,3-pdta (1,3-propanediamine-N,N,N′,N′-tetraacetate) ligand affects the structural and biological properties of the corresponding metal ...
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 ...
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 ...
Removal of methyl orange using combined ZnO/Fe2O3/ZnO-Zn composite coated to the aluminium foil in the presence of simulated solar radiation
(Switzerland : Springer Nature, 2022)
In this paper, the optimal preparative conditions (current density, deposition temperature, calcination temperature) for the original electrochemical synthesis of ZnO-Zn coating on aluminum foil support (ZnAF) were examined ...
Protection of Digital Elevation Model - One Approach
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
The quality of DEMs is especially being considered based on the spatial resolution of the created digital models and the type of terrain of the interest area. DEM analysis was performed specifically for LiDAR-based DEMs, ...
Sensitivity and fading of irradiated RADFETs with different gate voltages
(Elsevier, 2022)
The radiation-sensitive field-effect transistors (RADFETs) with an oxide thickness of 400 nm are irradiated with gate voltages of 2, 4 and 6 V, and without gate voltage. A detailed analysis of the mechanisms responsible ...
