Nitrogenous pollutants from wastewater pose a serious environmental concern and have to be managed by an efficient treatment technique. In this context, the main objective of this study was to remove nitrogenous pollutants (NH 4 + , NO 3 − , and NO 2 − ) from real brewery effluent using an adsorption (AD) process and to regenerate the saturated adsorbent through a direct anodic oxidation (DAO) process. The regeneration aimed at enabling the reuse of the adsorbent for additional applications. The experiments were conducted on brewery effluent sampled in N’Djamena (Chad). Adsorption tests were performed in batch mode by mixing a volume of effluent with a specific amount of activated carbon (AC) prepared from the core shell of Balanites Aegyptiaca . Based on the characterization results, the activated carbon exhibited an amorphous graphitic structure with the main functional groups (O–H, C-O, C = O), and a micro- and mesoporous structure showing a specific surface area of 153 m 2 g −1 . DAO was employed to enhance adsorption efficiency and to regenerate the active sites of the AC that had been previously saturated with pollutants. The maximum adsorption capacities for NH 4 + , NO 3 − , and NO 2 − ions were 40.16, 34.13, and 28.82 mg/g, respectively. The adsorption kinetics followed a pseudo-second-order model. Thermodynamic analysis revealed that the adsorption is endothermic with low enthalpy values (ΔH° = 3.40—9.02 kJ/mol), confirming that the adsorption mechanism is predominantly governed by physisorption involving Van der Waals forces and electrostatic interactions. The regeneration efficiency of saturated activated carbon via the DAO process was 84.29%, 88.57%, and 40.83% for NH 4 + , NO 2 − , and NO 3 − ions, respectively. Based on these findings, coupling AD and DAO processes is a viable method for treating effluents containing nitrogenous pollutants and effectively regenerates AC.

This work investigates the thermomagnetic response of La 2 O 3 ‐doped ZrO 2 /CoFeB heterostructures for energy harvesting applications. La 2 O 3 ‐doped ZrO 2 ceramic tapes were fabricated via tape casting, followed by the deposition of CoFeB ferromagnetic thin films using magnetron sputtering. This combined approach enabled the realization of hybrid systems exhibiting enhanced thermoelectric performance driven by the anomalous Nernst effect (ANE). Structural characterization by scanning electron microscopy and X‐ray diffraction confirmed the formation of La 2 O 3 ‐related phases in the ceramic matrix. Surface polishing improved the ceramic–ferromagnet interface, promoting the growth of soft magnetic CoFeB layers. The thermomagnetic response was evaluated by measuring the ANE under varying thermal gradients and external magnetic fields. The heterostructure with 2% La 2 O 3 doping exhibited the highest performance, with an effective coefficient of . These results demonstrate the potential of La 2 O 3 ‐doped ZrO 2 /CoFeB heterostructures for thermomagnetic energy harvesting and highlight the effectiveness of this fabrication route for achieving tunable thermomagnetic responses.

Magnetic skyrmions in heavy-metal/ferromagnet multilayers are promising building blocks for low-power spintronic devices; however, achieving thermally robust and field-free stability at room temperature remains a key challenge. Here, we present a combined experimental and micromagnetic investigation of confined skyrmions in Pt/Co/Ta multilayer nanodisks, with diameters ranging from 200 to 1000 nm, focusing on their switching behavior and numerical layer-resolved topological properties. Using polar magneto-optical Kerr effect, magnetic force microscopy, and micromagnetic simulations based on experimentally determined magnetic parameters, we show that lateral confinement strongly governs magnetization reversal and skyrmion stability. While continuous films exhibit labyrinthine stripe domains due to competing interfacial Dzyaloshinskii–Moriya interaction, exchange, and dipolar energies, nanodisks display pronounced size-dependent behavior: large disks remain multidomain, intermediate sizes favor skyrmion-mediated reversal, and sub-250 nm disks approach single-domain states. Notably, 400 nm nanodisks stabilize isolated Néel-type skyrmions at zero magnetic field and room temperature. Simulations reproduce the experimental hysteresis and reveal that confinement lowers the demagnetizing energy, stabilizing the skyrmion state. Layer-resolved topological analysis further uncovers two distinct remanent three-dimensional skyrmion configurations, selectable via modest fields (∼60 mT), with different chirality profiles and total topological charge. This controllable bistability provides a natural binary encoding scheme and, in a magnetic tunnel junction geometry, would enable nonvolatile memory operation through distinct resistance states.

The magnetization dynamics of Yttrium iron garnet (YIG)/ SnTe thin film heterostructure were investigated using the Magnetoimpedance effect. The oriented growth of the YIG layer on a (111) Gadolinium Gallium Garnet substrate was confirmed using X-ray Diffraction and the static magnetic properties were verified through Vibrating Sample Magnetometer (VSM). The magnetoimpedance response was used to evaluate the effect of the SnTe layer on the mechanisms behind the spin-pumping of two distinct YIG thicknesses, when compared to a reference sample of YIG/Ag. The results indicated that the SnTe successfully modified the effective damping parameter ( α eff ), as observed through peak broadening in the MI response and the related ferromagnetic resonance (FMR) parameters. The discussion is based on the different contributions to the FMR linewidth ( Δ H ). To elucidate the mechanisms underlying the modifications in the magnetoimpedance response, a theoretical approach is proposed, based on changes in two-magnon scattering and spin pumping, with YIG thickness as a variable to expand the simulations. Simulated results agree well with the experimental data. • Yttrium Iron Garnet heterostructures • Magnetoimpedance for FMR studies • Tin Telluride thin films for spin-pumping enhancement • Magnetron Sputtering for multistructure deposition

Developing highly efficient and stable electrocatalysts for electrochemical water splitting remains a significant challenge. In this work, a high-performance catalyst based on ceramic materials (titanium and tungsten carbides (G)) supported by graphene (C) (G/C) was prepared, characterized, and applied for removing an organic model compound (methylene blue (MB) dye) and the generation of oxygen gas. Scanning electron microscopy coupled with energy-dispersive spectroscopy revealed details of the material. The structural properties demonstrated that the synthesized nanocomposite consists of graphene, titanium carbide, and tungsten carbide phases. The application of the material for removing MB dye from textile effluent exhibited a maximum adsorption capacity of 175.44 mg/g at ≈ pH 5.5, with an adsorbent mass of 0.015 g and an operation time of 20 min. Meanwhile, when the material was used as an electrocatalyst for promoting the oxygen evolution reaction (OER), its catalytic activity was found to be remarkably efficient with good durability in strong alkaline media. However, the G/C nanocomposite exhibited an OER overvoltage of about 266 mV at a current density ( j ) of 10 mA cm -2 , remaining stable during 30 h. These significant results could be attributed to the strong link between the graphene support and the transitional metal-based carbides, as well as to the mesoporous structure, which provides more active adsorption sites, facilitates oxygen bubble release, and enhances mass transfer during OER kinetics. The synthesis of the G/C nanocomposite in this work paves the way for future large-scale treatment applications and energy-saving production.

High Resolution Image Download MS PowerPoint Slide The discharge of contaminated effluents containing organic dyes is a persistent environmental issue due to their toxicity, stability, and resistance to biodegradation. Among these dyes, malachite green (MG) is particularly concerning because of its widespread industrial use and severe ecological and health impacts. To address this problem, SnO 2 /Zn 2 –SnO 4 heterostructures were synthesized via sol–gel and evaluated for MG degradation under ultraviolet irradiation. The SnO 2 /Zn 2 –SnO 4 catalyst has been characterized by X-ray diffraction (XRD), photoluminescence (PL), field-emission scanning electron microscopy coupled with energy-dispersive spectroscopy (FE-SEM-EDS), ultraviolet–visible (UV–vis) spectroscopy, Brunauer–Emmett–Teller method, and electrochemical impedance spectroscopy (EIS). Structural properties revealed that the catalyst presents a polycrystalline structure and crystallite sizes in the range of 11–25 nm. The band gap energy of the Sn:Zn (1:2) catalyst was 2.88 eV, which was lower than that of pure SnO 2 (3.33 eV), indicating enhanced light absorption. MG photocatalysis degradation tests were conducted under ultraviolet irradiation. The ZnSn 1:2 sample achieved a degradation efficiency of approximately 96% after 100 min, while the pure SnO 2, ZnSn 1:4, and ZnSn 1:6 samples reached only 81%, 88%, and 92%, respectively. This could be due to the presence of h + and • OH species, which were identified as the most active radicals during the photocatalytic process. Furthermore, the 1:2 ZnSn photocatalyst demonstrated good stability and maintained its photocatalytic performance after five successive degradation cycles. These results indicate that the Zn/Sn 1:2 ratio results in the highest photocatalytic efficiency, confirming the superior effect of Zn 2 –SnO 4 structure in enhancing charge separation and accelerating the degradation of malachite green compared with the other compositions.

The proton exchange membrane electrolysis cell (PEMEC) is a practical approach for sustainable hydrogen production. To date, several studies have aimed to improve hydrogen production efficiency. This work examined the impact of electrolyte type and ultrasonics on hydrogen generation under static mode using a PEMEC. Therefore, the effects of three electrolytes (water, sulfuric acid, and phosphoric acid) were studied. The influence of electrolysis time, voltage, electrolyte concentration, and current intensity was optimized. Using the optimized parameters, the sono‐electrochemical process under indirect sonolysis was explored to improve the enhancement of hydrogen production efficiency. The results showed that electrolysis time and voltage significantly affect hydrogen generation in the PEMEC. Hydrogen production was highest with sulfuric acid at a concentration of 0.15 M, and a more concentrated solution negatively affected the mass transfer. Ultrasonic‐assisted electrochemistry also helped reduce electrolysis time from 30 to 10 min while increasing hydrogen efficiency. When using sulfuric acid 0.15 M, low electrolysis time (10 min), a current intensity of 55.0 mA, and a potential of 1.9 V, the maximum hydrogen efficiency was 92.9%. On the other hand, these parameters combined with the ultrasound effect allow reaching the maximum hydrogen efficiency of 99.9% at only 10 min of electrolysis. At the same time, the energy efficiency under sono‐electrolysis was increased from 24.2% to 32.8%. Our findings highlight the potential of the sono‐electrochemical process with PEMEC as a promising, efficient, and low‐time method for green hydrogen production compared to traditional hydrogen production methods.
