Cu–Au nanoparticles produced by the aggregation of gas‐phase metal atoms for CO oxidation

open access: yesAggregate, Volume 3, Issue 6, December 2022., 2022
The aggregation of gas‐phase Cu and Au atoms into Cu–Au nanoparticles with non‐equilibrium structures and compositions is studied using molecular dynamics. Density functional calculations reveal the significant effect of the structure of the obtained realistic models of Cu–Au nanoparticles on their CO and O binding properties as well as their CO ...

Toward Sustainable Photocatalysis: Addressing Deactivation and Environmental Impact of Anodized and Sol–Gel Photocatalysts

open access: yesAdvanced Sustainable Systems, EarlyView.
A life‐cycle evaluation of TiO2 photocatalysts for water purification compares the effectiveness of Sol–Gel vs anodic oxides in tetracycline mineralization, targeting deactivation, regeneration, and environmental impact from a cradle‐to‐grave perspective.

Charge generation in organic solar cells: Journey toward 20% power conversion efficiency

open access: yesAggregate, Volume 3, Issue 6, December 2022., 2022
Herein, a photophysicist's views on charge generation in organic solar cells is discussed. Recent steady‐state and time‐resolved spectroscopic studies regarding the exciton diffusion to donor:acceptor interfaces, charge transfer at the donor:acceptor interface, and long‐range spatial dissociation of charge transfer states are highlighted.

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

open access: yesAdvanced Theory and Simulations, EarlyView.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,
