Epitaxial growth of β-GaO nanowires on silicon substrates was realized by the low-pressure chemical vapor deposition (LPCVD) method. The as-grown Si/GaO heterojunctions were employed in the Underwater DUV detection. It is found that the carrier type as well as the carrier concentration of the silicon substrate significantly affect the performance of the Si/GaO heterojunction.

Organic molecules with reversible redox are emerging as promising materials for low power memristors. However, the structure-property relationship between the molecular structure and threshold voltage is not clear; achieving low threshold voltage memristors is still a challenge. To address this issue, a series of conjugated Blatter radicals with tunable redox were designed and synthesized by varying the functional groups.

Background: Carbapenemase-producing Citrobacter (CPC) species have recently been recognised as emerging pathogens associated with nosocomial infections in humans. The increased rate of Citrobacter freundii infections is a public health concern and there is a paucity of genomic data regarding its global transmission dynamics. We aimed to characterise the genetic features of CPC species, and their associated carbapenemase-encoding plasmids, obtained from hospitalised patients in China and from publicly available global data, with a particular focus on high-risk clones.

Phototransistors based on GaO are widely used in civil or military applications as a three-terminal device with solar-blind characteristics. This study constructed amorphous gallium oxide (a-GaO) thin film transistor (TFT)-based solar-blind photodetectors and explored the effect of the oxygen partial pressure on films and devices. It had been found that there is a strong correlation between oxygen partial pressure and photodetector properties.

Tigecycline is a last resort antibiotic that is used to treat serious infections; however, some bacteria have developed tigecycline resistance by producing a tigecycline-inactivating enzyme or tigecycline resistance efflux pump, encoded by (X) and genes, respectively. Tons of seafood are consumed annually in China; however, whether seafood harbors tigecycline-resistant bacteria is not known. In this study, we isolated various tigecycline-resistant bacteria from retail seafood; among these, was the predominant tigecycline-resistant genus (33/76, 43.

The retroperitoneal approach for RAPN minimizes interference with intraperitoneal organs but is constrained by a restricted operating space. The single-port (SP) robotic platform excels in navigating tight anatomical environments compared to the multi-port (MP) robotic system. However, there are not many studies that compare the results of surgery using these two platforms when the retroperitoneal approach is used.

Unlabelled: Plant height is a crucial agronomic trait in wheat, regulated by multiple genes, and significantly influences plant architecture and wheat yield. In this study, a novel dwarf mutant, designated as , was developed and characterized through the treatment of seeds from the common wheat cultivar Jinmai47 with ethyl methanesulfonate (EMS). Microscopic analysis revealed that the dwarf phenotype was attributed to a reduction in the longitudinal cell size of the stem.

Understanding the interaction of biotic and abiotic factors on ecosystem function is crucial for freshwater ecosystem management, However, the influence of nutrient enrichment, fungicide presence, and detritivore identity on leaf litter decomposition and associated fungal communities remains poorly understood. We conducted a microcosm experiment to examine: 1) the individual and combined effects of nutrient enrichment and a common fungicide on leaf litter decomposition and fungal communities; and 2) how two types of detritivore invertebrates (scrapers vs. shredders) influence these effects.

Despite improved sensitivity of iontronic pressure sensors with microstructures, structural compressibility and stability issues hinder achieving exceptional sensitivity across a wide pressure range. Herein, the interplay between ion concentration, mechanical properties, structural geometry, and aspect ratio (AR) on the sensitivity of lithium bis(trifluoromethanesulfonyl) imide/thermoplastic polyurethane (LiTFSI/TPU) ionogel is delved into. The results indicate that cones exhibit superior compressibility compared to pyramids and hemispheres, manifesting in an enhanced sensitivity toward the LiTFSI/TPU ionogel.

The articular cartilage is characterized by its gradient hierarchical structure, which exhibits excellent lubrication and robust load-bearing properties. However, its inherent difficulty in self-repair after damage presents numerous formidable challenges for cartilage repair. Inspired by the unique structure of articular cartilage, a biomimetic bilayer hydrogel composed of PAM (polyacrylamide) and PAM/SA (sodium alginate) is prepared using a two-stepswelling method.

This study examined the diversity and responses of intestinal microbiota in hybrid grouper ( ♀ × ♂) fed diets with varying levels of fishmeal replaced by black soldier fly larvae (BSFL). The 10% BSFL substitution (BSFL10) group showed the highest levels of trypsin and amylase. Substituting fishmeal with 30% and 50% BSFL weakened the intestinal wall, resulting in vacuoles, sparse striatal boundaries, and fewer villi.

Exciton-polariton condensates, due to their nonlinear and coherent characteristics, have been employed to construct spin Hamiltonian lattices for potentially studying spin glass, critical dephasing, and even solving optimization problems. Here, we report the room-temperature polariton condensation and polaritonic soft-spin XY Hamiltonian lattices in an organic-inorganic halide perovskite microcavity. This is achieved through the direct integration of high-quality single-crystal samples within the cavity.
