Summary: The study found that adding polyurethane powder at low contents did not significantly alter the final properties of the foam, but instead increased the foam's ability to retain carbon fillers. The compressive properties of the hybrid foams were unaffected by the addition of graphite and graphene. Additionally, the hybrid composites showed selective absorption capacity, maintaining the hydrophobic nature of the foams while providing oil absorption capacity.

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.
