In this study, the use of unsupervised machine learning for grouping organic coatings performance during corrosion testing is evaluated. Coatings with various pigments and pigment volume concentrations (PVC) were applied to AA2024-T3 and cold-rolled mild steel. The coated specimens were immersed in selected environments and periodically monitored with electrochemical impedance...
Gd2O3, a rare-earth oxide, is difficult to reduce because of its high thermodynamic stability. In the present study, the electrochemical reduction of Gd2O3 was attempted in the presence of less stable oxide, Fe2O3, in molten LiCl and CaCl2 melts at 650 and 900 °C, respectively. Gd2O3-Fe2O3 oxide precursor was electrochemically reduced by the FFC Cambridge process for the...
Free base and Cu(II)5-(4-carboxyphenyl)-10,15,20-tris(4-bromophenyl)porphyrin were synthesized and used to functionalize TiO2 nanoparticles. The porphyrins and conjugates were used to modify glassy carbon electrode for use as electrocatalysts for the electrochemical sensing of nitrite. The nanoparticles were synthesized via sol–gel procedure. The free base porphyrin was...
Results of an investigation of the action of various pyridinic and acetylenic brighteners during the electrodeposition of nickel are reported here. The focus was on the qualitative and quantitative analysis of the individual compounds 1-(3-sulphopropyl)-pyridinium betaine (PPS) and sulphopropylated 2-butyne-1,4-diol (HBOPS) and their reaction products. High performance liquid...
The global demand for poultry meat has increased, but consumers have become more picky in their nutritional choices. The fat content of poultry meat has risen since genetic advancement has resulted in higher rates of body weight gain and fat deposition, which are closely linked. The increase in further processing for fast-food poultry items has resulted in larger birds with more...
Manganese dioxide (MnO2) is a promising electrode material for supercapacitors due to its high theoretical specific capacitance. In this study, MnO2 particles were synthesized using a simple hydrothermal method and subsequently coated onto silver, nickel, and aluminum foils via dip coating. The structural, morphological, and functional properties of the resulting MnO2...
Maskless anodic oxidation with a continuous free jet of electrolyte can be used for the local surface functionalization and structuring of aluminum materials. In this study, a two-phase jet was applied with the aim of enhanced lateral confinement of the anodic oxide on the aluminum alloy EN AW-7075. The two-phase jet was realized by a coaxial arrangement. While the inner...
Green hydrogen can contribute significantly to combating climate change by helping to establish an energy economy that is both sustainable and carbon-free.
