Theoretical prediction of a novel 2D TiOBr monolayer with negative Poisson's ratio using first-principles calculations.

Two-dimensional (2D) materials with novel mechanical behaviors and electronic characteristics have attracted extensive attention in multiple cutting-edge fields in recent years. Based on first-principles calculations, we systematically investigate the mechanical properties and electronic characteristics of transition metal oxyhalide TiOBr in this work. Results demonstrate that the TiOBr monolayer exhibits metallic characteristics with Dirac points located above the Fermi level.

Deciphering the enzymatic responses, composition, network complexity, and functional degraders of the marine sediment bacterial community in response to 2-methyl-4-isothiazoline-3-one exposure.

2-Methyl-4-isothiazoline-3-one (MIT) is a widely employed antimicrobial agent frequently detected in environments; however, current documentation regarding its impacts on microbial communities and biodegradation processes remains limited. Herein, marine sediment systems were established to investigate the MIT impacts under tiered concentrations (CK, 0 μg/L; LC, 5 μg/L; MC, 50 μg/L; HC 5 mg/L). The extracellular polymeric substance contents increased in the LC and MC groups, but not in the HC group, after one day of exposure.

Strong Oxide-Support Interaction Induced Thermal Stabilization of Pt Single Atoms for Durable Catalytic CO Oxidation.

Supported metal nanoparticle catalysts often suffer from sintering-induced size-dependent deactivation, limiting their high-temperature applications. Although high-temperature redispersion offers a potential solution, this strategy remains restricted to reducible support materials, severely limiting the selection of catalyst supports with versatile compositions and tunable functionalities. Here, we engineer cationic vacancies at AlO-LaO interface via strong oxide-support interaction (SOSI)-driven interfacial reconstruction during calcination.

Exploring psychological distress among lung cancer patients through the stress system model.

Lung cancer, a leading cause of cancer-related mortality globally, often leads to anxiety, fear and other psychological distress due to its poor prognosis, treatment challenges, and financial burden. Prolonged distress may progress to depression or other mental health disorders, adversely affecting patients' quality of life and treatment outcomes. This study examines the prevalence and determinants of psychological distress in lung cancer patients, offering a theoretical basis for timely clinical interventions.

Under the trend of frozen ground degradation caused by global warming， the study on the spatial-temporal evolution and driving forces of ecological environment quality in different frozen ground regions of the Three-River Headwater Region （TRHR） can provide a theoretical basis for regional ecological environment governance and ecological civilization construction. The remote sensing ecological index （RSEI） was constructed based on the MODIS data set of google earth engine from 2000 to 2022， and the spatial-temporal evolution of ecological environment quality in different frozen ground regions of the TRHR was explored by coefficient of variation， migration of gravity center， Theil-Sen slope estimation， Mann-Kendall test， and Hurst index. The driving force of natural and human factors on the spatial differentiation of ecological environment quality was compared and analyzed by Geodetector.

Large negative Poisson's ratios and multiple single-spin Dirac cones in 2D VOX (X = F, Cl, Br, I) monolayers.

Half-metallicity and negative Poisson's ratio (NPR) are critical physical properties of two-dimensional (2D) materials. In this work, using first-principles calculations, we predicted a new class of stable 2D non-planar materials VOX (X = F, Cl, Br, I) that exhibit both half-metallicity and NPR characteristics. Among these, the VOF monolayer achieves an impressive NPR of -1.

Frequent water table depth fluctuations due to warm-dry conditions can significantly trigger carbon emissions from coastal salt marshes.

Coastal salt marshes are crucial for blue carbon storage, but their carbon emission patterns are uncertain due to frequent fluctuations in water table depth (WTD). This uncertainty is caused by the simultaneous impacts of global warming and rising sea levels. This study assessed carbon emission patterns in the Yellow River Delta under different hydrological fluctuation modes (high fluctuation of WTD scenario (HF-WTD) and low fluctuation of WTD scenario (LF-WTD)) and hydrothermal conditions through a 3-year in-situ observational experiment.

Cyanobacterial blooms specifically alter the dispersal-mediated taxonomic and functional vertical similarity of microbial communities in a subtropical reservoir.

Harmful cyanobacterial blooms, including Raphidiopsis raciborskii (basionym Cylindrospermopsis raciborskii), are an increasing environmental concern in freshwater ecosystems globally. However, the ecological consequences of cyanobacterial blooms for the vertical similarity of microbial community structure have yet to be thoroughly investigated, especially in deep waters. Here, we explored the taxonomic and functional similarity of microbial communities at different depths in a subtropical reservoir over a 7-year period following multiple R.

WTAP-mediated m6A modification on BASP1 mRNA contributes to ferroptosis in AAA.

Background: Abdominal aortic aneurysm (AAA) is a common aneurysm that is often associated with atherosclerosis and can lead to artery rupture and death. Brain abundant membrane attached signal protein 1 (BASP1) is related to a variety of pathophysiological processes, but its role in AAA has not been reported.

Methods: Real-time quantitative polymerase chain reaction (qRT-PCR) and western blot were used to detect the expressions of BASP1 and Wilms' tumor 1-associated protein (WTAP).

Modulation of NF-κB/Nrf2 signaling by nobiletin mitigates airway inflammation and oxidative stress in PM2.5-exposed asthmatic mice.

Exposure to fine particulate matter (PM) is a significant risk factor for asthma, promoting airway inflammation and oxidative stress. This study evaluates Nobiletin's (NOB) efficacy in mitigating airway inflammation and oxidative lung damage in asthma-induced mice exposed to PM. Using an ovalbumin (OVA) plus PM-induced asthma model in BALB/c mice, we investigated the therapeutic impacts of NOB compared to dexamethasone (DEX).

Urbanization leads to convergent succession and homogenization of phytoplankton functional traits in a subtropical watershed over 11 years.

Urbanization can significantly drive biodiversity loss in river ecosystems, yet the underlying mechanisms require further study. Here, we used a trait-based approach to investigate temporal succession and variation in the dissimilarity of phytoplankton community functional traits along an urbanizing subtropical river over 11 years - during which time the downstream of catchment underwent rapid urbanization. Our results indicated that urbanization altered the interannual succession of phytoplankton.

Manipulating Dynamic Light-Driven Solid-Liquid Transition and Static Reversible Photochromism by an Organic Cocrystal Strategy.

Developing of molecular crystalline materials with light-induced multiple dynamic deformation in space dimension and photochromism on time scales has attracted much attention for its potential applications in actuators, sensoring and information storage. Nevertheless, organic crystals capable of both photoinduced dynamic effects and static color change are rare, particularly for multi-component cocrystal system. In this study, we first report the construction of charge transfer cocrystal allows their light-induced solid-to-liquid transition and photochromic behaviors to be controlled by trans-stilbene (TSB) as an electron donor and 3,4,5,6-tetrafluorophthalonitrile (TFP) as an electron acceptor.

Impaired visual attention and numerical processing in children with anisometropic amblyopia and after visual acuity recovery.

Amblyopia affects more than visual acuity. To compare the performances of visual selective attention and numerical processing in children with anisometropic amblyopia and children with normal vision, and investigate whether performance would be improved after visual acuity recovery, we performed 3 visual attention tasks (identifying number location task, numerical comparison task, and specific number comparison task) in children with anisometropic amblyopia, children who had recovered from anisometropic amblyopia, and children with normal vision in 6-8 and 9-11 years groups. The numerical processing ability, visual selective attention, and numerical distance effect were assessed by their reaction time of different tasks.
