Summary: Hydrogel electrolytes have been widely studied in Zn metal batteries for wearable electronics, but the mechanical stability of the hydrogel under repeated deformation has been overlooked, resulting in unsatisfactory performance. This study explores the compressive fatigue-resistance properties of the hydrogel electrolyte and identifies the critical roles of the salt and copolymer matrix in crack initiation and propagation. An optimal Zn(ClO4)(2)-polyacrylamide/chitosan hydrogel electrolyte (C-PAMCS) is found to exhibit an unprecedented lifespan and high areal capacity for Zn//Zn cells, enabling potential applications in flexible Zn-ion batteries.

Summary: With the development of flexible electronic devices, there is a growing demand for power sources with higher safety, lighter weight, and bending ability. Aqueous zinc-ion batteries have gained attention due to their low cost, abundant zinc resources, and high safety. Despite their potential, the practical application of aqueous zinc-ion batteries is hindered by the unsatisfactory performance of cathode materials and complex manufacturing processes. This research explores a Ce doped-MnO2 binder-free cathode electrode for flexible zinc-ion batteries, demonstrating high reversible specific capacity, significant energy density, and excellent stability. The energy storage mechanism of the flexible zinc-ion batteries with Mn-based oxides cathode is also investigated, providing insights into the reversible insertion/extraction of ions during charge/discharge processes. Overall, this research opens up new opportunities for the use of flexible zinc-ion batteries in portable and wearable electronics.

Summary: A simple and effective strategy was proposed to solve the hot issues of existing flexible batteries by providing a uniform and stable framework for bendable, portable, and semi-transparent all-in-one lithium-ion batteries (LIBs). The fabrication of the all-in-one flexible LIB involved electrospinning of a PVDF-HFP-based precursor solution loaded with active materials, including nanostructured graphite and LiFePO4 as anode and cathode active materials, respectively. The addition of an optimized amount of CNT in the electrospinning solutions enhanced the electronic conductivity of the fibrous electrodes, resulting in stable electrochemical performance.

Summary: The difficulty of fabricating ohmic contacts on wide bandgap semiconductors like 13-Ga2O3 is addressed by inserting an n+-doped metal oxide layer between metal and the semiconductor layers. Pulsed laser deposition was used to deposit high crystallinity films of 13-Ga2O3, Erbium-doped ZnO (ErZO), and Gallium-doped ZnO (GZO). Investigation of the band offsets and electrical properties of ErZO/13-Ga2O3 and GZO/13-Ga2O3 heterojunctions revealed nested gap (type I) structures. The solar blind UV detector with a fork electrode structure of as-grown 13-Ga2O3/ErZO/Ti/Au showed superior performance due to ErZO's low band offset and small work function difference.

Summary: Ion implantation is an effective method for introducing defects into semiconductors. In this study, we investigated the use of crystallographically aligned implants to control the balance between optically active defects in ZnO. Optical data and structural analysis confirmed the formation of different dominant crystalline defects in samples implanted along and off the [0001] direction. The proportions of extended and point defects in the initial as-implanted states of these samples were found to significantly influence the defect-related luminescence upon annealing. We conclude that channeling implants have value in functionalizing defects in semiconductors by tuning specific spectral contents in defect-related emission bands.

Summary: This study fabricates monoclinic phase (BixGa1-x)2O3 ternary alloys on c-plane sapphire via magnetron co-sputtering and investigates their electrical properties. It is found that alloying Ga2O3 with Bi2O3 decreases the bandgap and lowers the self-trapping energy for holes. The conductivity of (Bi0.04Ga0.96)2O3 film is lower than that of undoped Ga2O3, likely due to the compensation of shallow donors by acceptors activated by Bi2O3-induced upward shift of the valence band edge.

Summary: High precision nanorod based surface morphologies can simulate the function of sensory hairs with nanotechnology. The unique gas sensitive I-V characteristics of these surfaces require initialisation under voltage bias and temperature elevation to exploit their band structures and achieve optimal gas response. Optimising nanorod based sensors with effective approaches can provide efficient control to downsize and miniaturise current gas sensors. By using ultraviolet photoelectron spectroscopy (UPS), specific band structure parameters can be extracted to determine the optimal sensor initialisation bias. The results validate the correlation between the fabricated nanostructured Schottky barrier heights obtained from UPS data and their I-V data, and also demonstrate the experimental validity of the proposed band structure. The optimal biasing condition of 0.8 V is determined for Au-ZnO nanorod hydrogen gas sensory operation at 150 degrees C, and the gas response data exhibit exponential dependence with gas concentration, which is highly relevant for programmable trigger response controlled sensing function based applications.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
