Herein, four Fe–N<sub>x</sub>–Cs electrocatalysts synthesized with different methodologies and displaying different morphological and physicochemical features were tested for ORR with a rotating ring disk electrode (RRDE) in the whole pH range. The trends of onset potential (E<sub>on</sub>), half-wave potential (E<sub>1/2</sub>), peroxide yield, number of transferred electrons (n), charge transfer coefficient (α) and logarithm of kinetic current densities (logJ<sub>k</sub>) along the pH scale were reported. Among the electrocatalysts, both unique behaviors and common electrochemical trends were identified, each characterized by varying rates of change. The occurrence of Fe agglomeration, the surface area and chemistry were found to influence the trends of these physicochemical quantities, giving rise to differences among the tested electrocatalysts. Therefore, the study concluded that the ORR electrocatalysts investigated possess different morphological and physicochemical properties developed during the distinct synthesis processes. Although similar electrochemical activity patterns were exhibited by the samples under analysis, differences in the rate of variations within such trends were noticed, signifying modulations in the reaction kinetics or mechanistic pathways due to contrasting morphological and physicochemical characteristics.

The European project BELENUS explored new materials and coatings to raise the operating temperature to 600 °C, thereby improving plant efficiency. Among the coatings under investigation, a super high-hardness steel (SHS) modified with Al, applied by high velocity oxy-fuel (HVOF) thermal spray on ferritic steel SVM12, has demonstrated an improved performance in the laboratory, exposed to a model biomass environment containing KCl deposits for 8000 h at 600 °C. Microstructural analysis by field emission scanning electron microscopy (FESEM) and X-ray diffraction was conducted on the tested samples to examine the coating’s evolution in these environments, as well as the associated protection and degradation mechanisms. The presence of Al within the coating significantly enhanced its resistance to biomass corrosion when compared to uncoated SVM12 and the Al-free SHS coating.

This review critically examines both conventional and emerging methods—including mechanical recycling, incineration for energy recovery, pyrolysis, gasification, hydrogenation, hydrocracking, and solvent-based treatments—focusing on their technical efficacy, environmental footprint, and economic feasibility. Mechanical recycling remains the most widely adopted method, involving collection, sorting, grinding, washing, drying, and granulation processes. However, challenges such as polymer degradation, contamination, and incompatibility among mixed plastics limit the quality and applicability of recycled products. Advanced sorting technologies, including Near-Infrared (NIR) spectroscopy, Artificial Intelligence (AI), and electrostatic separation, are increasingly employed to enhance recycling outcomes.

These techniques respectively evaluated the mechanical properties, phase composition, morphological features, and electrochemical corrosion behavior of the deposited coatings. X-ray diffraction (XRD) analysis revealed that the coatings consisted predominantly of the Ni₃Sn₂ intermetallic phase. Scanning electron microscopy (SEM) examination demonstrated that the Ni-Sn coating deposited using PC current exhibited superior surface uniformity but lower density compared to the direct current (DC) deposited coating. Microhardness measurements showed an increase from 238 HV (DC) to 297 HV for the ramp-wave PC coating. Electrochemical impedance spectroscopy revealed substantial improvements in charge transfer resistance (Rct), with PC-deposited coatings showing increases of 1570% (ramp), 554% (sinusoidal), 324% (triangular), and 83% (rectangular) relative to DC coatings. Correspondingly, potentiodynamic polarization measurements demonstrated that the corrosion current density (icorr) was reduced by factors of 14.5 (ramp), 3.2 (sinusoidal), and 2.9 (triangular) compared to the DC-deposited coating.
