Summary: The addition of TiO2 in magnesium based materials improves the efficiency of mechanical milling and enhances the hydrogen storage performance, especially in the as-milled (x = 5) alloy. The alloy exhibits an amorphous and nanocrystalline structure, and the TiO2 content has a slight effect on the thermodynamic properties of the alloys. The optimal hydrogen storage property is shown in the as-milled (x = 5) alloy due to its minimum dehydrogenation apparent activation energy.

Summary: Molybdenum carbides, specifically the alpha-MoC phase, exhibit enhanced CO2 adsorption, making them more efficient catalysts for CO2 hydrogenation at 130 degrees C. The synergistic effect of photothermal catalysis results in at least a 45% increase in activity compared to thermocatalysis on the same catalysts, due to light-promoted surface intermediate dissociation, specifically formate species. This study provides new insights into the photothermocatalytic synergistic effect.

Summary: Solid-state hydrogen storage with Mg added with high efficiency catalysts shows promise in breaking through the barrier of hydrogen storage materials. By adding single-metal (Al) and bimetal (Al, Zr) into Mg nanoparticles using the hydrogen plasma-metal reaction (HPMR) method, Mg-Al and Mg-Al-Zr nanocomposites with an approximate size of 100 nm were prepared. The addition of Al and Zr significantly accelerates the hydrogen absorption and desorption kinetics of Mg, with the Mg-Al-Zr nanocomposites showing enhanced kinetics compared to the Mg-Al nanocomposites. The nanostructure of Mg and the synergistic catalytic effects of active catalytic sites and H diffusion channels provided by the multiphase nanocatalysts contribute to the reduction of activation energy.

Summary: Al-Ti oxides supported noble-metal catalysts were prepared through mechanical ball-milling method and incipient wetness impregnation method, in which the etching of Al-Ti mixed oxides by phosphoric acid enhanced the propane oxidation performance. The phosphate-modified Pd/Al2O3-TiO2 catalyst with an Al/P ratio of 3:1 exhibited high catalytic activity, achieving over 90% conversion of C3H8 at 380 degrees C and GHSV of 100000 h-1, with the addition of 5 vol% H2O and 10 vol% CO2. The incorporation of Al2O3 and TiO2 provided a high specific surface area and excellent pore structure, while the phosphate modification enhanced the interaction between Pd species and the support, leading to better dispersion and catalytic stability. The presence of brilliant redox ability and abundant surface oxygen species in phosphate-modified Pd/Al2O3-TiO2 catalysts contributed to the activation of O2 and increased catalytic activity.

Summary: This study investigated the corrosion process of MgSi nano-precipitates in an Al-Mg-Si alloy using transmission electron microscopy. It was found that coarsened beta' precipitates in the over-aged state were corroded through dissolution of Mg and oxidation of Si, transforming into amorphous SiO2 precipitates. This newly discovered crystalline-to-amorphous phase transformation plays a role in intragranular corrosion behavior, explaining the reduced susceptibility of over-aged Al-Mg-Si alloys to pitting and intergranular corrosion.

Summary: This paper proposes a simple and efficient method for disposing of waste low-density polyethylene (LDPE) express packaging bags, aiming to minimize waste and address the energy shortage. Carbon nanotubes (CNTs) derived from LDPE were produced and tried as electrodes for supercapacitors. Waste LDPE bags were pyrolyzed and carbonized using a dual-temperature reaction system, and the effect of different carbonization temperatures and treatment durations on the product was investigated. CNTs synthesized at 750 degrees C showed the best properties with a high yield of 41.9% and carbon conversion of 61.2%. The electrode demonstrated good performance with a capacitance retention of 93.16% and a Coulomb efficiency of 92.85% after 10,000 cycles. The dual-temperature reaction system offers an efficient way to recycle waste LDPE, and LDPE-derived CNTs can be applied in supercapacitors.

Summary: Magnesium and its alloys are extensively studied for solid-state hydrogen storage, but there are challenges in the kinetics and thermodynamics of hydrogenation and dehydrogenation. Severe plastic deformation methods have been utilized to improve the activation, air resistance, and kinetics of Mg-based hydrogen storage materials by introducing ultrafine/nanoscale grains and crystal lattice defects. These deformed materials, particularly with alloying additives or second-phase nanoparticles, exhibit fast hydrogen absorption/desorption kinetics and good cycling stability. The study also highlights the application of severe plastic deformation methods in hydrogen binding-energy engineering and the synthesis of new magnesium alloys for reversible low/room-temperature hydrogen storage.

Summary: In this study, varying amounts of FeOOH were generated in situ on an amorphous Fe78Si9B13 alloy ribbon through potentiostatic cathodic corrosion treatments of different durations. These samples, labeled R-0.5h, R-1h, R-2h, and R-5h, were then evaluated as electrocatalysts for the oxygen evolution reaction (OER) in 1 M KOH. The optimal catalytic performance was observed in the R-1h sample, which achieved an overpotential of 356 mV at a current density of 10 mA cm-2 and a Tafel slope of 45 mV dec-1.

Summary: This study characterized the tribological behaviors of a Zr-based BMG material against GCr15 steel balls under different loads and frequencies. It was found that high coefficient of friction (COF) was observed under low load and high frequency, while low COF was observed under high loads or at low frequencies. The specific wear rate increased with both load and frequency, with frequency playing a more crucial role. Transition of wear mechanisms from oxidative wear and abrasive wear to adhesive wear was detected with increasing load and frequency, and the role of plastic deformation of BMG was illustrated. This study helps to understand the tribological properties of Zr-based BMGs under sliding conditions.

Summary: Severe plastic deformation (SPD) processes are effective methods to refine grains, introduce crystal defects, and improve mechanical properties and functionality. High-pressure torsion (HPT) is particularly useful for preparing hydrogen storage materials, as it can process powders and induce greater plastic deformation. HPT technology not only allows for the preparation of bulk samples and enhances various properties of hydrogen storage materials, but also enables the synthesis of new alloys, intermetallics, composites, and even immiscible Mg-based alloys.
