Summary: A novel solid-liquid two-phase precipitation method was proposed for the synthesis of high-quality fullerene nanowires, showing a narrower diameter distribution compared to the widely-used liquid-liquid interfacial precipitation method. The gradual melting of the solid-phase C-60 in m-xylene is believed to provide a more stable interface for crystal growth.

Summary: The pressure-dependent structural properties of the metallofullerene salt Li+@C-60][PF6](-) were studied, and it was found that the structure remains a primitive cubic at both ambient and low temperatures, without any phase transition. The interaction between the endohedral Li+ and the interstitial [PF6](-) unit has little influence on the structure, as indicated by the comparable bulk moduli to other cubic close-packed fullerene solids.

Summary: Weberite-type sodium transition metal fluorides show potential as high-performance sodium intercalation cathodes, but the inconsistencies in the structure and properties of Na2Fe2F7 have hindered the understanding of structure-property relationships. In this study, a combined experimental-computational approach is used to reconcile the structural characteristics and electrochemical behavior of Na2Fe2F7, revealing the presence of multiple polymorphs and their transformation to more stable phases upon cycling. These findings emphasize the importance of controlling polymorphism and phase stability for improved performance.

Summary: Research has shown that encapsulating fullerene C-60 inside zeolitic imidazolate framework-8 can act as a catalyst for the oxygen reduction reaction, with significant interactions between the host ZIF-8 and guest C-60 modifying the electrochemical behavior of C-60. Mono-confinement of C-60 inside ZIF-8 also effectively maintains its dilute solution-like behavior and enhances its electrochemical performance.

Summary: Developing a low-cost, non-toxic, efficient, and high electrochemical activity supercapacitor device requires careful selection of electrode materials. Metal phosphate based electrode materials are preferred due to their open framework structure and enhanced ionic conductivity. In this report, Ammonium Oxonium Dodeca Molybdophosphate (NH4)2.6(H3O)0.4(PMo12O40) open channel microcubes are synthesized using a simple co-precipitation method. These microcubes exhibit a maximum specific capacitance of 752 F g-1 at a current density of 2 A g-1.

Summary: The potential of a single boron-doped fullerene in catalytic reduction of nitrogen monoxide was examined using density functional theory calculations. The results showed that the boron atom effectively activated the nitrogen monoxide and resulted in the formation of different molecules at different coverages. Based on the Gibbs free energy diagram, it was inferred that the boron-doped fullerene exhibited excellent catalytic activity for nitrogen monoxide reduction at ambient conditions.

Summary: The study found that exposure to FC60 led to increased oxidative stress in clams, significant changes in antioxidant enzyme activities in gills, and damage to lipids and proteins in digestive glands. FC60 accumulation was higher in digestive glands compared to gills, and haemolymph parameters were slightly affected by FC60 exposure. Overall, clam gills were identified as the target tissue for FC60 toxicity, with potential long-term consequences for the organism due to damage to lipids and proteins.

Summary: This study presents a simple method using rubrene as a structure-directing agent to transform 2D C-60 microsheets into highly ordered nanorod arrays. The results suggest that the intermolecular charge-transfer interactions between rubrene and C-60 enable the reassembly of dissolved C-60 into ordered nanorod arrays. The aligned structures and charge-transfer interactions contribute to a 31.2% improvement in photocurrent density of the nanorod arrays in the UV region compared to randomly oriented counterparts.

Summary: The molecular and ionic assemblies at the electrode/liquid electrolyte interfaces play a crucial role in defining battery performance. The dielectric nature of the electrode material greatly affects the composition of the interfacial metal-anion-solvent, leading to different interphase chemistry. This suggests that different initial cycling conditions should be established for forming the desired interphase on a case-by-case basis.

Summary: The dynamics of Sc3N@C-80 and C-60 in crystal lattice containing NiOEP were studied using VT-XRD. The result suggests that fullerene cages exhibit stronger libration than NiOEP, while the Sc3N cluster rotates perpendicular to the NiOEP plane driven by temperature. The difference in temperature dependent behavior of the Sc3N cluster compared to other similar structures like Ho2LuN and Lu3N indicates the influence of metal ion mass and size.

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.
