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

Advanced 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‐

Integral equation analysis of multiport H‐plane microwave circuits by using 2D rectangular cavity Green's functions accelerated by the Ewald Method

IET Microwaves, Antennas &Propagation, Volume 17, Issue 1, Page 13-25, January 2023., 2023
Abstract An integral equation technique for the analysis of multiport H‐plane microwave circuits composed of an unlimited number of arbitrarily shaped metallic and/or dielectric elements is proposed. The structure under study is divided into different regions after the application of the surface equivalence principle.

Photo‐Biomodulation of the Hippocampus Using Near‐Infrared Laser to Enhance Cognitive Function in Mice

Advanced Science, EarlyView.
Here a transcranial photo‐biomodulation approach is developed using near‐infrared (NIR) laser on hippocampus of mice, revealing significant improvements in learning and memory ability of mice under normal and disease conditions. The improvement results from the high‐density cell‐induced NIR local energy deposition, neuronal activation, and axonogenesis

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities

Advanced Science, EarlyView.
This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal

Enhancement of Optical Transparency and Electrical Conductivity of IZO/Ag/IZO Multilayer Film by Intense Pulsed Light and its Effect on the Photovoltaic Performances of Perovskite Solar Cells

Advanced Science, EarlyView.
The highly conductive IZO/Ag/IZO multilayer transparent electrode is successfully fabricated through flashlight annealing (FLA) process. A transient thermal effect of FLA maintains the continuous Ag interlayer and improves the crystallinity of the sandwich IZO layers. This combination increases both electric conductivity and optical transmittance.
