Transient Creep in Olivine at Shallow Mantle Pressures: Implications for Time‐Dependent Rheology in Post‐Seismic Deformation

open access: yesGeophysical Research Letters
Transient creep in olivine aggregates has been studied by stress‐relaxation experiments at pressures of 1.7–3.6 GPa and at temperatures of ≤1020 K in a DIA apparatus. Time‐dependent deformation of olivine at small strains (

Updated Insights Into the Mechanism of Salt‐Induced Aggregation‐Based Single‐Molecule Surface‐Enhanced Raman Spectroscopy

open access: yesAdvanced Science, EarlyView.
A salt‐gradient model is proposed to investigate the physical nature and update insights into the single molecule surface‐enhanced Raman spectroscopy (SM‐SERS). The release of Ag+ ions from the Ag NPs and the final formation of precipitate of AgCl with Cl‐ on the surface of the aggregated Ag NPs plays as the active and packaging shell to improve the SM‐

Constructing High‐Performance Inverted Perovskite Solar Cells Using Chiral Organic Molecules

open access: yesAdvanced Science, EarlyView.
This study presents a strategy for passivating defects at perovskite interfaces using chiral molecules. A comparison between the chiral R‐, S‐, and rac‐MBACl molecules reveals that S‐MBACl exhibits the strongest chelating ability and defect passivation effect on the perovskite surface. Finally, PSCs based on S‐MBACl modification achieve a PCE of 24.07%.

Electrical Manipulation of Field‐Free Magnetization Switching Driven by Spin‐Orbit Torque in Amorphous Gradient‐Mn3Sn

open access: yesAdvanced Science, EarlyView.
A highly efficient spin current with z‐polarization is achieved in amorphous Mn3Sn with a spontaneous composition gradient, which allows field‐free magnetization switching. Spin current efficiency and magnetization switching polarity are reversibly manipulated by ionic liquid gating, enabling logic functions by pure electrical methods. This work offers

Dissolution of Spent Lithium‐Ion Battery Cathode Materials: Overlooked Significance of Aluminum Impurities

open access: yesAdvanced Science, EarlyView.
During the mechanical crushing of retired lithium‐ion batteries, aluminum foil from current collectors may penetrate NCM active crystals through frictional contact, forming more stable Al─O bonds. The dissolution behavior of critical metals in NCM cathodes will be influenced to varying extents by different mechanisms in various hydrometallurgical ...
