Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

open access: yesAdvanced Physics Research, EarlyView., 2023
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Precision Nanoconfined Self‐Assembly of ACQ Carbon Dots for Enhanced Solid‐State Fluorescence

open access: yesAdvanced Science, EarlyView.
Star‐liked polymer unimolecular micelles are used as a general and robust nanoconfined scaffold template to fabricate structurally ultra‐stable and solid‐state fluorescence CDs assemblies via the conduction of ACQ‐to‐Solid state fluorescence transition process with ACQ CDs as the building units, which realized potential applications in detecting latent

Exploration of Oxygen Reduction Reaction Catalyzed by FePPc and Pz‐FeTPr Conjugated Organic Polymer: Insights From Grand‐Canonical Density Functional Theory

open access: yesAdvanced Science, EarlyView.
At alkaline conditions (pH = 13), for FePPc and Pz‐FeTPr at low potential (less than 0.5 V), the ORR mechanism is the *O2 mechanism (O2→∗O2→∗OOH→∗O→∗OH→H2O${{\rm{O}}_2} \to ^*{O_2} \to ^*OOH \to ^*O \to ^*OH \to {H_2}O$), Fe is the active site; for Pz‐FeTPr at high potential (larger than 0.5 V), the Fe site is covered by O2−$O_2^ - $, the nearby C site

Effect of Inhomogeneous Temperature in Chip‐Scale Infrared Thermal Sources: A Revisited Blackbody Radiation Formula with Experimental Validation

open access: yesAdvanced Electronic Materials, EarlyView.
Revisited Black‐body radiation formula accounting for nonuniform temperature is proposed for calibration of planar thermal light sources. Calibration of optical power is based on measurement of the highest and lowest temperatures. Abstract Miniature and low‐cost light sources are highly desirable for numerous optical microsystems.
