Summary: In this work, a penta-coordinated Fe single atom with N on a N-doped carbon support (Fe-N-5/C) was found to be an efficient catalyst for CO2RR to produce tunable compositions of syngas. The potential-limiting step for CO2RR on the Fe-N-5/C surface was identified as CO2 activation to COOH*, leading to enhanced CO2RR and suppressed hydrogen evolution reaction (HER). The H2/CO ratio ranged from 0.15 to 2.8 when Fe-N-5/C was used as the catalyst for CO2RR in 0.1 M KHCO3.

Summary: T-carbon, a newly discovered diamond-like phase, shows potential as a high-capacity Li storage material and Li battery anode. The adsorption of Li to T-carbon is influenced by the valence electrons of Li filling into the antibonding pi* orbitals of acetylene bonds. At low Li density, strong adsorption hinders Li release and anode discharge, while at high Li density, Li atoms push against each other and resist T-carbon adsorption, leading to a decrease in anode potential.

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.
