Summary: In this study, K2NiF6 was used as an additive to improve the dehydrogenation properties of LiAlH4. The addition of K2NiF6 significantly reduced the decomposition temperature and enhanced the dehydrogenation kinetics of LiAlH4. The morphology study showed that the LiAlH4 particles became smaller and less agglomerated when K2NiF6 was added. The in situ formation of new phases during the dehydrogenation process, as well as a reduction in particle size, were believed to contribute to the improved dehydrogenation characteristics of LiAlH4.

Summary: The dehydrogenation temperature of LiAlH4 can be significantly reduced by producing mixtures with ZrCl4 through ball milling at low temperatures. This method allows for efficient hydrogen release by achieving small aggregate size and preventing substantial decomposition. However, the LiAlH4/ZrCl4 mixtures are unstable and difficult to handle. The dehydrogenation pathway is changed in the mixtures, resulting in the formation of Al, LiCl, Zr, and H2 as the main products.

Summary: Hydrolysis of LiAlH4 is a promising way to produce hydrogen at low temperatures, and an anti-icing aqueous solution is necessary. In this study, an optimized solution containing 27.1% KOH and 30.0% ethylene glycol was found to achieve full and controllable hydrolysis kinetics of LiAlH4 at -40 to 0 degrees C. The effects of compactness, mass, and temperature on the hydrolysis were investigated, and it was observed that the reaction followed the shrinking core model controlled by liquid film diffusion.

Summary: Mixtures of LiAlH4/FeCl2 and LiBH4/FeCl2 were prepared under cryogenic conditions using ball milling, with the optimal production conditions being milling for 30 minutes at -196 degrees C and 15 Hz oscillation frequency. Hydrogen release in LiAlH4/FeCl2 mixtures starts at around 60 degrees C, while LiBH4/FeCl2 mixtures exhibit dehydrogenation starting at 40 degrees C and finishing at about 300 degrees C. The formation of LiCl is considered the driving force behind the decomposition reactions in these reactive mixtures. Cryogenic ball-milling has a positive effect on production and low-temperature dehydrogenation of the studied samples.

Summary: In this study, rare earth oxide nano-CeO2 additives with different morphologies (nanoparticles, nanocubes, and nanorods) were prepared by the hydrothermal method, and their intrinsic properties were characterized. The addition of nano-CeO2 to LiAlH4 improved its dehydrogenation behavior, with the LiAlH4-CeO2-nanorod composite exhibiting the optimal dehydrogenation behavior. The hydrogen release was facilitated by the in-situ formed CeH2.73 and the facile transition between the oxidation states of Ce4+ and Ce3+.

Summary: This research aims to investigate the effect of adding titanium silicate (TiSiO4) on the dehydrogenation behavior of lithium alanate (LiAlH4). The addition of 10 wt% TiSiO4 resulted in lower dehydrogenation temperatures for LiAlH4, with the first-step reaction occurring at 92 degrees C and the second-step reaction at 128 degrees C. The TiSiO4-added LiAlH4 composite was able to release more hydrogen (about 6.0 wt%) compared to undoped LiAlH4 at 90 degrees C for 2 hours. The addition of TiSiO4 also reduced the activation energies for hydrogen liberation from LiAlH4.

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: It is reported that the addition of activated carbon (AC) improves the hydrogen storage ability of ball-milled lithium alanate (LiAlH4). LiAlH4-10 wt.% AC composite exhibits lower onset decomposition temperature, enhanced desorption kinetics, and higher hydrogen release compared to as-received and as-milled LiAlH4. The presence of Li3AlH6 and carbon bonding in the LiAlH4-10 wt.% AC composite is verified by XRD and FTIR measurements.

Summary: LiAlH4 is a promising material for hydrogen storage due to its high hydrogen storage capacity and release at a moderate temperature. However, it suffers from slow kinetics and irreversibility issues. This study focused on reducing the onset desorption temperature and quickening the desorption kinetics of LiAlH4. By adding 10 wt.% of LaCoO3, the desorption temperature of LiAlH4 decreased to 70℃ for the first stage and 156℃ for the second stage. Moreover, LiAlH4 + 10 wt.% LaCoO3 desorbed 3.37 wt.% H2 at 90℃ in 80 min, which was 10 times faster than the unsubstituted samples. The in situ formation of AlCo and La or La-containing species in the presence of LaCoO3 contributed to the enhanced hydrogen desorption kinetics of LiAlH4.

Summary: The renal vasculature plays a crucial role in kidney function both in normal physiology and in disease. However, current imaging techniques lack sufficient resolution to assess its structure and function. To develop realistic models and diagnostic methods, we propose a hybrid framework that combines automated segmentation and optimization algorithms to create subject-specific models of the renal vascular network. Our results demonstrate a close agreement with existing anatomical data, validating the accuracy of our approach.

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.

It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
