28 de may. de 2024 · The derived Cu clusters composed of at least three Cu atoms can efficiently promote CO–CO coupling, as revealed by kinetic analyses. We extend the modeling to other typical Cu SACs and reveal that all of the Cu 1 sites are inactive, while the C 2+ performance of the derived Cu-cluster catalysts is substrate-dependent.
Hace 2 días · The experimentally determined nuclear quadrupole coupling constants (NQCC) for molecules and molecular complexes, denoted as χ, are proportional to the electric field gradient at the quadrupolar nucleus, making χ a reflection of the local electron distribution and an indicator of the nature of the chemical bond involving the quadrupolar nucleus.
Hace 5 días · Coupling and Cohesion are two key concepts in software engineering that are used to measure the quality of a software system’s design. Both coupling and cohesion are important factors in determining the maintainability, scalability, and reliability of a software system.
16 de may. de 2024 · Abstract. Metal sulfides exhibit good catalytic activity for the oxygen evolution reaction (OER) due to their distinctive electronic and structural properties; however, their inadequate electrical conductivity hinders electron transfer, while easy agglomeration obstructs active sites.
13 de may. de 2024 · As the CO–CO coupling is the rate-determining step for the eCO 2 R reaction towards the C 2 products, the good alignment between the Fermi level of Cu and these frontier MOs is proposed to be the origin of Cu as a unique catalyst for this reaction.
1 de jun. de 2024 · A one-to-one correlation between strong electron–phonon coupling, as reflected in the Fano antiresonance in Raman spectra, with q ≈ 0, and the geometrical rotation of the Fe–O–Fe bond angle that has been observed.
16 de may. de 2024 · Our study provides detailed insight into the exciton–phonon coupling and its role in carrier cooling in two-dimensional perovskites relevant for developing emerging hybrid semiconductor ...
