In article number 2300628, Park, Cho, Im, and co-workers delve into charge transport characteristics of organic transistors, depending on the alkyl chain length of organic semiconductors and the surface polarity of polymer dielectric layers. The in-depth interface analysis reveals that the surface polarity can be abated with the introduction of an alkyl chain in organic semiconductors, resulting in high-performance organic devices.
In article number 2301049, Wang, Liu, and Fan summarize the design of signal amplification strategies in nanozyme-based biosensors for highly sensitive detection of trace disease biomarkers. This review aims to serve not only as a reference for enhancing the sensitivity of nanozyme-based biosensors but also as a catalyst for exploring nanozyme properties and their broader applications in biosensing.
In article number 2300718, Tonti, Giorgetti, and co-workers demonstrated the formation of charge state inhomogeneities inside the Manganese hexacyanoferrate cathode material via synchrotron-based transmission soft X-ray microscopy. Special image treatment procedure was adopted to highlight the heterogeneities on Fe and Mn oxidation state. The advantage of using Na-ion system over Li-one were detected.
In article number 2300848, Yue, Qian, Yang and co-workers developed a novel near-infrared photothermal method to manipulate cellular excitability and animal behaviors in Caenorhabditis elegans (illustrated as a light bulb) in vivo via the thermosensitive TRPV1 channels (illustrated as a switch) with indocyanine green, which is an FDA-approved photothermal agent.

Oxide‐Halide Perovskite Composites for Simultaneous Recycling of Lead Zirconate Titanate Piezoceramics and Methylammonium Lead Iodide Solar Cells
- 10 December 2023
Graphical Abstract
Recycling hazardous but widely used electronic components will benefit addressing global energy- and environmental issues. This study demonstrates simultaneous recycling of broken piezoceramics used for sensors and waste perovskite-based solar cells by creating oxide-halide perovskite composites. The recycling procedure consumes only marginal energy compared to manufacturing new materials. The recycled materials are also given a second life for sensing application.
Hetero-Solvation-Diluted Strongly-Coordinated Zn2+-Cosolvent Pairs Downshifting Zn Electrode Potential for High-Voltage Hybrid Batteries
- 10 December 2023
Graphical Abstract
With a mild hybrid electrolyte containing in situ-derived diluted strongly-coordinated Zn2+-cosolvent pairs, a considerable Zn anode potential downshift is initially achieved. The electrolyte environment with hetero-solvation-diluted strongly-coordinated Zn2+-cosolvent pairs remarkably lowers Zn2+ activity, responsible for the downshift (−0.330 V vs Zn). As-assembled Zn-MnO2 hybrid battery delivers a ca. 0.278-V higher voltage plateau (1.57 V) than that in common hybrid electrolytes.
Enhancing Performance of GaN/Ga2O3 P-N Junction Uvc Photodetectors via Interdigitated Structure
- 10 December 2023
Graphical Abstract
GaN/Ga2O3 PN junction photodetector with improved responsivity and outstanding response speed is prepared by utilizing the interdigitated electrode structure to enhance carrier collection efficiency and intensified electric field. Notably, the fast decay time at 0 V is only 2.76 µs, which is the fastest values ever reported. This work also proves the pivotal role of perimeter in influencing device performance.

A Review of Direct Z‐Scheme Photocatalysts
- 18 April 2017
Graphical Abstract
The direct Z-scheme heterojunction is applied to enhance photocatalytic performance due to its ability to spatially separate photogenerated electron–hole pairs and optimize the redox potential of a photocatalytic system. Future development of direct Z-scheme photocatalysts will greatly stimulate the practical application of photocatalysis in energy conversion and environmental remediation.

Recent Progress of Rechargeable Batteries Using Mild Aqueous Electrolytes
- 19 September 2018
Graphical Abstract
Rechargeable batteries using mild aqueous electrolytes (pH is close to 7) provide a promising solution for the large-scale energy storage and wearable/biocompatible applications due to the high safety and low cost. Three development tendencies of these batteries are summarized: charge carriers from monovalent ions to multivalent ions; electrolyte composition from “salt-in-water” to “water-in-salt”; electrodes from inorganic materials to organic materials.

Graphical Abstract
Searching for highly efficient and stable electrocatalysts for N2 fixation is critical to NH3 synthesis. Here, it is proposed that a single tungsten atom anchored on g-C3N4 exhibits superior catalytic performance for N2 reduction to NH3 due to its low limiting potential, significant suppressing effect for HER, and good stability.
