The pursuit of advanced brain‐inspired electronic devices and memory technologies has led to explore novel materials by processing multimodal and multilevel tailored conductive properties as the next generation of semiconductor platforms, due to von Neumann architecture limits. Among such materials, antimony sulfide (Sb2S3) thin films exhibit outstanding optical and electronic properties, and therefore, they are ideal for applications such as thin‐film solar cells and nonvolatile memory systems. This study investigates the conduction modulation and memory functionalities of Sb2S3 thin films deposited via the vapor transport deposition technique. Experimental results indicate that the Ag/Sb2S3/Pt device possesses properties suitable for memory applications, including low operational voltages, robust endurance, and reliable switching behavior. Further, the reproducibility and stability of these properties across different device batches validate the reliability of these devices for practical implementation. Moreover, Sb2S3‐based memristors exhibit artificial neuroplasticity with prolonged stability, promising considerable advancements in neuromorphic computing. Leveraging the photosensitivity of Sb2S3 enables the Ag/Sb2S3/Pt device to exhibit significant low operating potential and conductivity modulation under optical stimulation for memory applications. This research highlights the potential applications of Sb2S3 in future memory devices and optoelectronics and in shaping electronics with versatility. [ABSTRACT FROM AUTHOR]

The high ionic conductivity and chemical stability of poly(aryl piperidinium) (PAP) underpin its extensive use in anion exchange membranes (AEMs) for water electrolysis (WE) and fuel cell (FC) applications. Nonetheless, the limited elongation of PAP-based AEMs negatively impacts cell performance and durability. Their high ion exchange capacity (IEC), while enhancing cell performance, often causes excessively high water uptake and diminishes the mechanical properties and phase separation performance. This study developed high-performance AEMs by crosslinking two polymers with contrasting characteristics: poly(dibenzyl N-methyl piperidine) (PDB), a rigid PAP-based unit, and poly(styrene-b-ethylene-co-butylene-b-styrene) (SEBS), a flexible unit with good phase separation. Notably, the pentafluorobenzoyl group was incorporated into SEBS to enhance microphase separation. AEMs were developed with pentafluorobenzoyl contents ranging from 4 to 12% (labeled as x-PDB-m-F5-SEBS, m = 4, 8, and 12), and the results were compared with the x-PDB-0-F5-SEBS membrane without the pentafluorobenzoyl group. All x-PDB-m-F5-SEBS membranes exhibit low hydrogen permeability, excellent chemical stability, and a conductivity retention of over 99% after 1080 h. x-PDB-4-F5-SEBS demonstrated the most pronounced microphase separation, coupled with high ionic conductivity. It also achieved excellent WE cell performance (3.204 A cm−2 at 1.8 V), significantly surpassing that of commercial membranes including FAA-3-50 and PiperION. Even when using a non-precious metal catalyst (Ni2Fe) in place of IrO2, the membrane exhibited a cell performance of 3.364 A cm−2 at 1.8 V, equivalent to that achieved with precious metal catalysts. When applied to AEM-based FCs, x-PDB-4-F5-SEBS also exhibited a high-power density of 785 mW cm−2, highlighting its significant potential as an AEM in WE and FC applications. [ABSTRACT FROM AUTHOR]

The increasing demand for electric vehicles (EVs) has prompted extensive research in the development of lithium-ion batteries (LIBs) with high volumetric energy density. The graphite anode possesses a tap density of 2.25 g cc−1, resulting in a volumetric energy density of over 770 W h L−1. However, the practical electrode density of 1.4–1.6 g cc−1 leads to a lower volumetric energy density of ∼550 W h L−1, and increasing electrode density beyond 1.6 g cc−1 is limited owing to the pore closure and poor electrolyte penetration, which leads to an imbalance in the N/P ratio resulting in Li metal plating. Hence, enhancing the electrolyte permeation into the densely packed graphite electrode is the crucial aspect for achieving high volumetric energy density. In this research, we coated a functional polymer (cyanoethyl polyvinyl alcohol), which has a high electrolyte absorption capability on a conventional graphite anode to enhance the electrolyte penetration into the highly densified graphite. As a result, the electrode demonstrated a high cycle stability under a high electrode density of 1.9 g cc−1 without any Li plating, and drastic degradation of capacity retention resulted in a remarkable volumetric energy density exceeding 650 W h L−1.

Orostachys spp., considered economically important succulent plants for both the medicinal and ornamental plant industries, are known to exhibit slow growth in their offsets during the long, cold winter months. Due to the slow growth, this study investigated the application of gibberellic acid (GA3) and determined the optimal GA3 concentration (control, 200 mg·L−1, 400 mg·L−1, and 600 mg·L−1) for promoting the propagation of three Orostachys species (i.e., O. fimbriata, O. japonica, and O. minuta), as well as its impact on their growth and development. According to our study findings, O. fimbrata and O. minuta influenced by GA3 exhibited higher survival rates (7–38%) and offset growth rates (3–87%) compared to the control. Similarly, its application resulted in significant shoot and root development, along with increased moisture content for the majority of the species. The results of this research demonstrate the potential and practical applications of using GA3 to increase the propagation and growth of Orostachys spp. during cold conditions for year-round propagation of these succulent plants, which could have ecological and horticultural significance for related species as well as other vegetatively propagated crops.
