Summary: A composite material of 0.71 LiBH4-0.29 NaBH4 and CMK-3 carbon with nanopores was successfully synthesized, showing improved hydrogen absorption-desorption kinetics. After five cycles, the composite maintained a consistent uptake of about 3.5 wt.% H-2. The enhanced kinetics were attributed to carbon-hydride surface interactions and the heat transfer capability of the carbon support. The nanopore confinement may also contribute to the improved reversibility.

Summary: The thermodynamic behavior of complex borohydrides confined in mesoporous hollow carbon spheres was investigated, showing no variation of equilibrium plateau pressure upon changes in the hydrogen sorption temperatures. This is interpreted as a result of the high pressure within the carbon nanopores, providing a means to control the thermodynamics of nanosized hydrides.

Summary: The study demonstrates a new approach to thermodynamically stabilizing metastable metal hydrides by coordinating them with nitrogen binding sites within nanopores. This allows for low-temperature hydrogen release and regeneration of LiAlH4 at high pressure, with a predicted decrease in Al-H bond dissociation energy. Additionally, solid-state reversibility is achieved through a combination of nanoconfinement effects, Li adatom formation, and charge redistribution between the metal hydride and the host.

Summary: Metal-organic frameworks (MOFs) show promise for hydrogen storage, with reversible and high-rate hydrogen adsorption as main benefits, but operation at very low temperatures as a drawback. Factors affecting hydrogen adsorption in MOFs are studied, and nanoconfinement of metal hydrides inside MOFs is proposed as a new approach for hydrogen storage. Incorporating metal nanoparticles in MOFs for future prospects as nanoscaffolds and/or H-2 sorbents is summarized.

Summary: Energy production, distribution, and storage are crucial for various applications in our daily lives, such as renewable energy systems, electric vehicles, and consumer electronics. Hydrogen is the only element that promises high energy, emission-free, and sustainable energy, and metal hydrides have been explored as promising materials for this purpose. However, metal hydrides have limitations in terms of kinetics, operating temperatures, recyclability, stability, and environmental concerns. Nanotechnology offers a strategy to overcome these limitations by embedding reactive hydride compounds in nanosized graphene supports.

Summary: The formation of homogeneous solid solutions at high temperatures, as well as the decomposition into two chemically different solid solutions during annealing, have been studied in AuCuNiPdPt and AuNiPdPt alloys. Different annealing treatments result in different microstructures, allowing for the evaluation of the effect of chemical compositions and their size on the mechanical properties. Softening of the alloys is observed, along with a decrease in hardness with increasing concentration modulation amplitude and decomposed solid solution size.

Summary: We present advancements in in-situ magneto-transport measurements using a transmission electron microscope. This approach allows for simultaneous magnetic imaging, high-resolution structural analysis, and chemical characterization of the same sample. Our proof-of-principle measurements on nickel thin films, supported by micromagnetic simulations, demonstrate the importance of detailed knowledge of the sample's structure and composition for accurate interpretation of the magneto-transport data. This in-situ approach is expected to enhance our understanding of the Hall effect in more complex magnetic textures.

Summary: This study presents a simple strategy to control chemical gradients in solutions using local photo-electric surface charging of organic semiconducting thin films. By irradiating carbon nitride thin films with ultra-violet light, sustained surface charges are generated in illuminated regions, inducing chemical gradients in adjacent solutions. Experimental measurements show that these gradients respond to changes in temperature, chemistry, and concentration.

Summary: The domain structure of thin Nd2Fe14B lamellae is studied in this paper. Magnetic bubbles with a minimum diameter of 74 nm were observed at room temperature, approaching the range of magnetic skyrmions. Both the stripe domain width and the bubble size are dependent on the thickness. Moreover, a kind of bubble combining bubbles with opposite helicity was observed below the spin-reorientation transition temperature. The study reveals Nd2Fe14B to be a good candidate for high-density magnetic bubble-based memory.
