Summary: This study demonstrates the tuning of ZnO nanosheet-nanowire morphology by adjusting the NaOH concentration in a low-temperature chemical bath, resulting in a variety of nano/microstructures with different sizes and aspect ratios. Photoluminescence spectra were mainly influenced by violet emission from Zn interstitial related defects formed during growth. In dye-sensitized solar cells, ZnO nanosheets with a thickness of 30-40 nm exhibited superior performance in terms of J-V characteristics and transport dynamics.

Summary: Porous sea urchin-like nickel-doped ZnO with various nickel contents were synthesized and showed superior sensing performance for VOCs. The 10% Ni-doped ZnO sea urchin sensor exhibited a high response of 84.4 and short response/recovery times for formaldehyde vapor. These superior sensing behaviors were attributed to suitable Ni content, high oxygen defects, small nanocrystals, and a porous hierarchical structure with high specific surface area.

Summary: The combination of electric double-layer and pseudo-capacitive materials can enhance the specific energy and specific capacitance of electrode materials in supercapacitors. In this study, nanocomposites of Lily-based Porous activated Carbon Material (LPCM) loaded with Ni-Co Layered Double Hydroxide (LDH) were prepared using a hydrothermal method. The LPCM@NiCo-LDH-N2H4 electrode exhibited a high specific capacitance of 705C g-1 at 1 A g-1 (577C g-1 at 30 A g-1), three times higher than the LPCM electrode. The assembled LPCM@NiCo-LDH-N2H4//LPCM asymmetric supercapacitor demonstrated excellent specific energy (53.3 Wh kg-1) at 800 W kg-1 with minimal capacitance loss after 10,000 cycles, outperforming other supercapacitor devices. Connecting two asymmetric devices could power a colored snowball and a small LED for over 13 minutes.

Summary: A sieve-like interface assembled with ZnO porous sheets is reported to stabilize zinc anodes in Zn-based electrochemical energy storage systems. The sieve-like structure effectively homogenizes the Zn2+ flux during zinc plating and restricts zinc dendrite growth, while the hydrophobic feature of ZnO porous sheets alleviates corrosion behavior. Under the protection of the sieve-like interface, the electrochemical properties of zinc anodes are significantly improved, leading to prolonged cycling life and enhanced stability in zinc-ion batteries and zinc-ion hybrid supercapacitors.

Summary: This study found that serum zinc levels decreased with the progression of liver diseases and were independently associated with serum albumin and cholinesterase levels, as well as daily furosemide dose. In patients receiving zinc supplementation, a serum zinc level of less than 50 μg/dL was associated with the development of overt hepatic encephalopathy, while furosemide use was not associated. The Child-Pugh score at baseline was the only factor associated with the maintenance of sufficient serum zinc levels.

Summary: Most studies on WC-based cermet coatings have focused on their erosion, corrosion, and wear resistance. However, there is limited research on the effect of WC-based cermet coatings on the mechanical properties of the coating system. In this study, a WC-10Co4Cr coating was prepared using High-Velocity Oxygen Fuel technology (HVOF) on AISI 4135 steel substrate, and the tensile and fatigue properties of the HVOF-sprayed WC-10Co4Cr coating system were investigated. The results showed that the WC-10Co4Cr coating degraded the tensile properties of the coating system, with a more noticeable effect observed with thicker coatings. Additionally, the fatigue life of the coating system decreased under different loads when sprayed with WC-10Co4Cr coating.

Summary: In this article, an intelligent feedforward prediction and compensation scheme combined with a dual-loop high-bandwidth controller is proposed for high-speed and high-precision tracking controls of a nanopositioning stage. The dual-loop controller, consisting of an inner loop damping and an outer loop tracking controller, is developed with optimized parameters to provide a control bandwidth over the first resonant frequency of the stage. The effectiveness of the intelligent tracking error prediction method and the excellent performance of the control strategy for high-precision tracking of high-frequency reference trajectories are validated through experimental investigations on a self-made piezoelectric-actuated stage.

Summary: Continuous plant growth relies on cell division and elongation, which is regulated by brassinosteroids (BR). In this study, the researchers used cotton fiber to investigate cell-specific BR signaling and found that the transcriptional activator GhBES1 promotes fiber elongation by activating GhCERP, a protein related to cell elongation. GhCERP then transmits the BR signal to its target gene GhEXPA3-1, which ultimately promotes fiber cell elongation. Furthermore, the BR-mediated BES1-CERP-EXPA3 signaling cascade also promotes root and hypocotyl growth in Arabidopsis, indicating its broad significance in regulating BR-promoted cell elongation.

Summary: We conducted the first multi-color light curves analysis of the eclipsing binary V2769 Ori. The photometric solution using the Wilson-Devinney method revealed that V2769 Ori is a deep, low-mass-ratio contact binary with a reliable contact degree and mass ratio. We constructed and analyzed the O-C diagram and found a long-term period decrease and a periodic oscillation. The period decrease can be attributed to mass transfer and angular momentum loss, while the periodic oscillation may be caused by the light-travel time effect.

Summary: Mimicking brain perceptual processing and using biocompatible and biodegradable materials in neuromorphic devices are both important for the design of bionic intelligent systems. In this study, a gelatin/carboxylated chitosan composite electrolyte film was used as the gate dielectric in oxide neuromorphic transistors, successfully mimicking synaptic plasticity. A quantitative processing method for tactile recognition based on spike number dependent synaptic plasticity was proposed, and an artificial neural network achieved a recognition accuracy of over 90% for MNIST handwritten digits. The results show that the proposed GEL/C-CS gated neuromorphic device has promising application potential in the design of bionic intelligent systems and brain-inspired neuromorphic systems.

Summary: This paper proposes a general parametric repetitive control (GPRC) method based on the IIR filter to address the limitations of repetitive control in terms of sensitivity to frequency shift and undesired gain amplification. By analyzing its sensitivity function, it is found that the design of GPRC can be converted to the explicit parametric design of an IIR high pass filter. Comparative experiments show that GPRC exhibits excellent robustness against frequency shift and advanced performance at the aperiodic frequencies.
