Published: Sept. 25, 2023

Abstract Aqueous zinc ion batteries are attracting broad interest in stationary energy storage where low cost, robust security, and satisfactory capacity matter most. However, metal anodes suffer from destructive dendrite issues during repeated charging/discharging process, decreasing the cycle life of batteries. Herein, smoother plating/striping behaviors achieved by group modification structural unit polymer separator. Experimental results theoretical simulations reveal that skeleton can release more easily when modified with carbonylation side groups contribute to much faster transfer capability. Typically, symmetric Zn cells a thin thickness separator 21 µm exhibit ultralong over 2800 h at 1 mA cm −2 within mAh 300 under high current density 5 areal 3 . Full using sodium vanadium oxide cathode also show stable reversible performance after 2000 cycles A g −1 This work is expected inspire promising strategies molecular design polymeric toward stabilizing beyond this anode itself.

A Biomass-Based Colorimetric Sulfur Dioxide Gas Sensor for Smart Packaging

ACS Nano, Journal Year: 2023, Volume and Issue: 17(7), P. 6849 - 6856

Published: March 27, 2023

Sulfur dioxide (SO2) gas, which can effectively prohibit the growth of pathogenic microorganisms, has been internationally used in commercial food packaging to maintain high-quality and reduce incidence foodborne illnesses. However, current mainstream methods for SO2 detection are either large expensive instruments or synthesized chemical-based labels, not suitable large-scale gas packaging. Recently, we discovered that petunia dye (PD), is extracted from natural flowers, demonstrates a highly sensitive colorimetric response with its total color difference (ΔE) modulation reaching up 74.8 limit down 1.52 ppm. To apply smart real-time sensing food-quality prediction, flexible freestanding PD-based label prepared by incorporating PD biopolymers assembling films through layer-by-layer approach. The developed utilized predict grapes' quality safety monitoring embedded concentration. could potentially be as an intelligent sensor status prediction daily life, storage, supply chains.

Non‐Contact Triboelectric Nanogenerator

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(52)

Published: Sept. 8, 2023

Abstract With the rapid development of science and technology, there is an increasing demand for sustainable energy sources. Although triboelectric nanogenerators (TENGs) can realize self‐powered supply by using various weak mechanical energy, device's robustness reliability are seriously affected frequent, direct, long‐term shocks, as well negative environmental factors during equipment operation. Therefore, researchers have developed non‐contact (NC‐TENGs) based on principle electrostatic induction. This technology enables electricity generation via relative movement friction layers even when they not in direct contact, which consequently leads to enhance device robustness, prolonged service life, broadened operation scenarios. In this review, recent progress NC‐TENG from fundamental theory practical applications systematically summarized. The basic structure working first introduced, followed a discussion devices’ structural construction performance optimization methods. Furthermore, automatic force position detection system, human‐machine interface, electrical harvesting reviewed. Finally, brief prospectus future provided.
