Encapsulated Organohydrogel Couplants for Wearable Ultrasounds

open access: yesAdvanced Electronic Materials, EarlyView.
Hydrogels are ideal for wearable ultrasonic devices but suffer from water loss during long‐term monitoring. Adding excessive glycerol increases attenuation, while elastomer encapsulation causes uneven interfaces due to shrinkage and scattering acoustic waves.

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.

A High Throughput Platform to Minimize Voltage and Fill Factor Losses

open access: yesAdvanced Energy Materials, EarlyView.
A high‐throughput workflow is developed to determine the Langevin reduction factor in organic photovoltaics autonomously and accurately within seconds. Using UV–Vis spectra, current–voltage curves, and transient absorption kinetics, intrinsic charge absorption cross‐sections are calculated.

The Role of Thermally Activated Charge Separation in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Charge separation mechanism in state‐of‐the‐art system has been a part of intense debate. Here, it is presented that as, the system moves toward the low‐offset regime the thermal contribution plays an important role to derive the charge separation. The rational guide is provided to achieve the maximum CSE and maximum VOC simultaneously within the mid ...

Dynamic Defect Tolerance in Metal Halide Perovskites: From Phenomena to Mechanism

open access: yesAdvanced Energy Materials, EarlyView.
Defect tolerance is the key feature that dominates the high performance of perovskite devices. MHPs exhibit dynamic defect tolerance at practical working condition, which is intrinsically relevant to their soft‐lattice thus mixed ionic‐electronic conduction, and intimately correlated with charge carrier, phonon, lattice, and mobile ions and determine ...

Efficient Forward‐Bias Bipolar Membrane CO2 Electrolysis in Absence of Metal Cations

open access: yesAdvanced Energy Materials, EarlyView.
Alkali‐metal cations are assumed to be indispensable for CO2 reduction, but often lead to undesired failure mechanism such as salt precipitation due to the non‐electrochemical CO2 conversion to (bi)carbonates. A promising alternative CO2 reduction cell design involves the use of pure water and a metal cation‐free forward‐bias bipolar membrane ...
