Silence as a Quiet Strategy: Understanding the Consequences of Workplace Ostracism Through the Lens of Sociometer Theory.

Existing research has predominantly framed defensive silence as an avoidance response to interpersonal mistreatments. Moving beyond this view, this study theorizes defensive silence as a proactive strategy for managing interpersonal relationships through the lens of sociometer theory. We posit that workplace ostracism will reduce employees' organization-based self-esteem (OBSE), which in turn increases their subsequent defensive silence to avert further damage to relationships.

Fluorine- and Trifluoromethyl-Substituted Biphenyl Derivatives: Promising Antimicrobial Agents Targeting Escherichia coli FabH.

This study investigates the synthesis, antibacterial activity, structure-activity relationships (SARs), and molecular docking of F- and CF-substituted biphenyl derivatives (5A-5K) as potential antimicrobial agents. Ten novel biphenyl derivatives were synthesized, incorporating trifluoromethyl (CF) and fluorine (F) substitutions, to evaluate their efficacy against various bacterial strains, including Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae. Antimicrobial assays demonstrated that the F substitution significantly enhanced antibacterial activity, with the bis-F derivative (5D) showing improved potency compared to the other compounds.

Quasi-Homojunction Based on 1D-Chained Alloyed SbSe for High-Performance Broadband Photodetection and Matrix Imaging.

Junction-based photodiodes play a crucial role in integrated devices due to their compactness and efficient rectification. However, three-dimensional (3D) semiconductor heterojunctions suffer from high interface defects caused by lattice mismatch, while one-dimensional (1D) semiconductors feature large interchain gaps that alleviate lattice matching requirements and provide high strain relaxation, making them highly promising for homojunction construction. Herein, a quasi-homojunction is constructed via in situ Bi doping in 1D SbSe.

Highly flexible TFT monolithic-integrated (Bi,Sb)Se SWIR photodetector for wearable health monitoring and curved-surface imaging.

Flexible short-wavelength infrared (SWIR) detectors are significant for wearable health monitoring, artificial vision systems, etc. However, it is difficult to realize flexibility in mainstream SWIR photodetectors, like InGaAs and HgCdTe, because of high fabrication temperature and epitaxial growth on single-crystal substrates. Herein, we report a highly flexible thin-film transistor (TFT) monolithic-integrated SWIR photodetector based on one-dimensional (Bi,Sb)Se.

Drivers of the emergence and dissemination of high-risk resistance genes in cattle farm.

Extended spectrum β-lactamase (ESBL)- and carbapenemase-producing Enterobacterales (CPE) are recognized by WHO as critical concerns. The high cephalosporin resistance rate in a cattle farm in 2018 prompted us to conduct long-term (2019-2023) and extensive monitoring to explore risk factors for the import and transmission of ESBLs and CPE in this farm. Among 1288 samples from cattle, the environment, milk, and biological vectors, 48.

Mechanisms of anthraquinone dye Vat Blue 4 biodegradation by Pseudomonas aeruginosa WYT and genotoxicity assessment of its transformation products.

Dye biodegradation products may cause genotoxicity, raising concerns about the safety of bioremediated water. The underlying biotransformation mechanism and related genotoxicity during anthraquinone degradation remain unclear. In this study, we employed Pseudomonas aeruginosa WYT (PaWYT) to investigate the biotransformation of Vat Blue 4 (VB4), a dye with a typical anthraquinone structure and low bioavailability.

Spatial variations in health service utilization among migrant population: a perspective on health equity.

As health equity becomes a prioritized goal in global health policy, extensive research has revealed that socio-economic and geographical factors jointly exacerbate barriers to medical service access for both internal and international migrant populations, further accelerating existing health disparities. This study explores healthcare service utilization disparities among internal migrants in China, a population profoundly affected by the country's economic reforms and urbanization since the late 1970s. These transformations have led to significant migratory movements and subsequent healthcare challenges for these populations.

(Bi,Sb) Se Alloy Thin Film for Short-Wavelength Infrared Photodetector and TFT Monolithic-Integrated Matrix Imaging.

Short-wavelength infrared photodetectors play a significant role in various fields such as autonomous driving, military security, and biological medicine. However, state-of-the-art short-wavelength infrared photodetectors, such as InGaAs, require high-temperature fabrication and heterogenous integration with complementary metal-oxide-semiconductor (CMOS) readout circuits (ROIC), resulting in a high cost and low imaging resolution. Herein, for the first time, a low-cost, high-performance, high-stable, and thin-film transistor (TFT) ROIC monolithic-integrated (Bi,Sb) Se alloy thin-film short-wavelength infrared photodetector is reported.

Molecular Ferroelectric Crystals with Superior Pyroelectricity, Plasticity, and Recyclability.

The pyroelectric effect is used in a wide range of applications such as infrared (IR) detection and thermal energy harvesting, which require the pyroelectric materials to simultaneously have a high pyroelectric coefficient and a low dielectric constant for high figures of merit. However, in conventional proper ferroelectrics, the positive correlation between the pyroelectric coefficient and the dielectric constant imposes an insurmountable challenge in upgrading the figures of merit. Here, we explored superior pyroelectricity in [(CH)N][FeCl] (TMA-FC) and [(CH)N][FeClBr] (TMA-FCB) molecular ferroelectric plastic crystals, which could decouple this positive correlation due to the nature of improper polarization behavior.

Logic Control of Directional Long-Range Resonance Energy Transfer On 2D DNA Nanosheet.

By arranging fluorophores in a directional way on a 2D DNA nanosheet that transfers energy from the initial donor to the acceptor through homogeneous Förster resonance energy transfer (homo-FRET), it is found that the photonic wires (PWs) based on cascade long-range resonance energy transfer (LrRET) up to 15.6 nm can be effectively achieved through the rational selection of the fluorophores and the adjustment of their position with different distance. Then, logic control of directional energy transfer is achieved with the blocking of the energy transfer pathway, making two tumor-associated microRNA (miRNA) inputs produce an obvious output with the association of tumor diagnosis only when they present simultaneously.

Direct asymmetric reductive amination of α-keto acetals: a platform for synthesizing diverse α-functionalized amines.

We report an efficient and straightforward method to synthesize enantio-enriched -unprotected α-amino acetals ruthenium-catalyzed direct asymmetric reductive amination. The α-amino acetal products are versatile and valuable platform molecules that can be converted to the corresponding α-amino acids, amino alcohols, and other derivatives by convenient transformations.

Homo-FRET enhanced ratiometric fluorescence strategy for exonuclease III activity detection.

In this work, homo-FRET (Förster resonance energy transfer between the same kind of fluorophores) takes place in a hetero-FRET (FRET between two different fluorophores) system and can effectively improve the energy transfer efficiency. Herein, a novel ratiometric fluorescence method was developed for the detection of nuclease activity. Exonuclease III (Exo III), an enzyme which has a high exodeoxyribonuclease activity for double-stranded DNA (dsDNA) in the 3' to 5' direction, was chosen as a proof of concept of this strategy.

Submicron-Sized Nb-Doped Lithium Garnet for High Ionic Conductivity Solid Electrolyte and Performance of Quasi-Solid-State Lithium Battery.

The garnet LiLaZrO (LLZO) has been widely investigated because of its high conductivity, wide electrochemical window, and chemical stability with regards to lithium metal. However, the usual preparation process of LLZO requires high-temperature sintering for a long time and a lot of mother powder to compensate for lithium evaporation. In this study submicron LiLaZrNbO (LLZNO) powder-which has a stable cubic phase and high sintering activity-was prepared using the conventional solid-state reaction and the attrition milling process, and Li stoichiometric LLZNO ceramics were obtained by sintering this powder-which is difficult to control under high sintering temperatures and when sintered for a long time-at a relatively low temperature or for a short amount of time.
