Summary: The study examines ultrafast transmission changes around the fundamental trion resonance in a negatively charged II-VI quantum dot after exciting a p-shell exciton. The biexcitonic induced absorption reveals quantum beats between hot-trion states at 133 GHz. The relaxation of the P-shell hole within 390 fs dominates interband dephasing, while trionic coherence remains stored in the spin system for 85 ps due to Pauli blocking of the triplet electron.

Summary: This study theoretically determines the electronic and optical signatures of CdSe/CdS core/shell dot-in-hexagonal platelet nanocrystals, showing a reduction in excitonic band gaps with increasing CdS shell sizes and a decrease in oscillator strengths, excitonic binding energies, and stokes shift with increasing CdSe shell sizes.

Summary: Hierarchical porous copper (HPC) was synthesized by Cu-Zn liquid phase alloying on a Cu tube followed by vapor pressure dealloying. The HPC exhibited ligament sizes of 0.61-1.97 μm and residual Zn contents of 29-2 at%. The coarsening exponent and activation energy suggested that the ligament formation and coarsening were dominated by surface diffusion of Cu atoms on the Cu surface. The HPC showed significantly enhanced double-layer capacitance and current density for CO2 reduction compared to electropolished Cu. The CO2 reduction products transformed from formic acid to carbon monoxide and ethanol. (c) 2022 Elsevier B.V. All rights reserved.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
