Preparation, characterization, and antibacterial application of cross-linked nanoparticles composite films.

This study aimed to prepare a composite film by blending cross-linked tapioca starch (CLTS) with sodium alginate (SA), silver nanoparticles (AgNPs), and ZnO nanoparticles (ZnOs). The effects of SA, AgNPs, and ZnOs at different concentrations (1-3 wt%) on the mechanical properties, optical properties, thermal stability, and antibacterial activity of cross-linked starch films were also investigated. The structures of the films were examined by Fourier transform infrared spectroscopy and X-ray diffraction.

Photoinduced Long-Distance Charge Transfer in Silicanes: The Stacking Matters.

The generation of interlayer charge transfer excitons upon photoexcitation is strongly desirable for two-dimensional (2D) materials stacked through van der Waals interactions. In this work, we investigate photoinduced charge transfer in silicanes (SiH) with three typical stackings. A concept of the regional natural hole orbital and its conjugated particle orbital is developed to characterize excited states in solids.

Multiexposure Grayscale Patterns with Low-Energy Electrons.

High-energy electron beam exposure is generally recognized as the standard for achieving high-precision nanofabrication. Low-energy electron beam exposure techniques offer advantages in 3D manufacturing; however, they have received limited attention in traditional processes due to precision limitations and insufficient exposure, leading to an underestimation of their potential. In this article, we introduce a nanofabrication strategy using low-energy electrons in ice-assisted electron-beam lithography (iEBL) alleviating the compatibility issue between resolution and quasi-3D manufacturing.

Single-cell RNA sequencing reveals intrahepatic signature related to pathobiology of duck hepatitis A virus type 3 (DHAV-3) infection.

DHAV-3 is one of the main causative agents of duck viral hepatitis (DVH), an acute and highly lethal infectious disease in duck industry. However, the understanding of the pathogenesis of this virus in ducklings is limited. To dissect the molecular characteristics associated with pathobiology of ducklings to DHAV-3, we applied single-cell RNA-sequencing approach to profile the transcriptome of 1.

Influence of Different Mixing Methods for Cementitious Capillary Crystalline Waterproofing Materials on the Self-Healing Capacity of Concrete Under Various Damage Types.

Cementitious Capillary Crystallization Waterproofing Material (CCCW), as an efficient self-healing agent, can effectively repair damage in concrete structures, thereby extending their service life. To address the various types of damage encountered in practical engineering applications, this study investigates the impact of different mixing methods for CCCW (including internal mixing, curing, and post-crack repair) on the multi-dimensional self-healing performance of concrete. The self-healing capacity of concrete was evaluated through water pressure damage self-healing tests, freeze-thaw damage self-healing tests, mechanical load damage self-healing tests, and crack damage self-healing tests.
