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: A study on the filling of a carbon matrix with pores of distinct sizes using LiBH4 was conducted, revealing that smaller pores are filled faster. Different resins were mixed to create a material with micropores and four populations of mesopores, leading to experiments with various volumes of LiBH4 and subsequent thermodynamic analysis. A two-step pore filling protocol was proposed to investigate the efficiency of doping the matrix with boron for improved filling, highlighting the inherent difficulties in reversibility of the system.

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: The thermochemical reaction between MgH2 and Li2CO3, with and without nickel as a catalyst, was investigated for CO2 transformation into fuels. Successful production of high-yield CH4 was achieved by controlling reaction conditions such as microstructural refining, MgH2:Li2CO3 molar ratio, temperature, and time. The presence of nickel catalyst significantly improved the methane yield. The results demonstrate the potential of thermochemical activation of MgH2:Li2CO3 mixture for CH4 generation and CO2 utilization.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.

Summary: A detailed understanding of the interaction between molecules and two-dimensional materials is crucial for incorporating functional molecular films into next-generation 2D material-organic hybrid devices. This study compares the energy level alignment of different-sized fullerenes on a Moire superstructure and finds that C-84 fullerenes can be either neutral or negatively charged depending on slight variations of the electrostatic potential. This discovery suggests a new path to achieve ambipolar charge transfer without overcoming the electronic gap of fullerenes.
