Solar oscillations as a guide to solar structure
The Astrophysical Journal, 1976 The theoretical spectrum of frequencies for the radial oscillations of a solar model is shown to depend on the treatment of convection near the model surface. For example, the period of the fundamental radial mode can vary from 48 minutes to 66 minutes, depending on the treatment.

Molecular Conversion of Thermally Stable Cu‐Ag Networks for Mechanically Robust Printed Electronics
Advanced Science, EarlyView.An air‐processable Cu–Ag reactive ink enables in situ formation of an Ag‐surface‐enriched Cu conductive network. Optimized Ag distribution suppresses Cu oxidation while preserving continuous electrical pathways, allowing printed conductors to achieve high conductivity, reduced migration, and stable operation at extreme temperatures up to 800 °C in air.

Developing slurries for carbon capture: From synthetic gas mixtures to flue gas
AIChE Journal, EarlyView.Abstract Deep eutectic solvent (DES)‐based systems have recently emerged as promising alternatives to conventional liquid sorbents for CO2 capture due to their tunable properties and potential for enhanced mass transfer. In this work, two DES‐based slurry systems previously developed for CO2 capture, one aqueous and one non‐aqueous, were further ...

Angewandte Chemie International Edition, EarlyView.The overpotential constitutes an electrochemical potential difference at the solid–liquid interface, which can manifest itself in different ways. In general, it can not only drive the reaction along the reaction coordinate, but also modulate chemical potentials in the extended environment that shape activation barriers, without necessarily being a ...
