Synthesis and Structure of Uranium Disilyl-Substituted Alkylidene Complexes.

J Am Chem Soc

March 2025

State Key Laboratory of Coordination Chemistry, Jiangsu Key Laboratory of Advanced Organic Materials, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210023, China.

Understanding the participation of f-orbitals of actinide elements in covalent bond formations is less explored, compared to the well-studied d-orbitals of transition metals, leading to the significant interest in actinide-carbon multiple bonds. Uranium alkylidene complex, containing an alkylidene linkage of the form U═CR (R = H, alkyl, silyl), represents a key milestone in actinide-ligand multiple bonding, but their isolation and characterization have remained elusive. Herein, we present the synthesis of an unprecedented uranium disilyl-substituted alkylidene complex, achieved through sequential dehydrogenation reactions of a methyl group under mild conditions.

Preclinical application of a CD155 targeting chimeric antigen receptor T cell therapy for digestive system cancers.

Oncogene

March 2025

Henan Key Laboratory for Helicobacter pylori & Microbiota and GI cancer, Marshall Medical Research Center, The Fifth Affiliated Hospital of Zhengzhou University, Zhengzhou, 450052, Henan, China.

Despite intensive multimodal therapy, the prognosis for patients with digestive system cancers remains poor. Cancer cell heterogeneity and immunosuppressive microenvironments are the main barriers to the effective CAR-T cell therapy with solid malignancies. In parallel, tumor-associated macrophages (TAMs) are essential for tumor immunosuppressive microenvironment formation.

Background: Academic burnout is a common mental health issue among college students, particularly pronounced among students majoring in music education. Despite evidence that professional identity influences academic burnout, the mechanism of action remains unclear, particularly the relationship between academic self-efficacy and academic burnout. Furthermore, research specifically addressing the connection between professional identity and academic burnout among music majors is relatively limited.

The Trait Anxiety Attention Control Theory suggests an imbalance in high trait anxiety individuals between bottom-up and top-down processing. To investigate this theory, we designed an experimental paradigm combining task-switching and Stroop tasks to investigate behavioral and neuroelectrophysiological features in trait anxiety. The results revealed a significant negative correlation between trait anxiety levels and switch costs, indicating a preference for automatic processing among those with high trait anxiety.

School of Chemistry and Chemical Engineering/State Key Laboratory Incubation Base for Green Processing of Chemical Engineering, Shihezi University, Shihezi, 832003, PR China. Electronic address:

Hydrogen sulfide (HS) is a pivotal signaling molecule in plants and appropriate levels are essential for normal growth. As such the real-time detection of HS in plants is required since it enables timely targeted interventions. However, most fluorescent probes for detecting HS reported to date exhibit fluorescence quenching in aqueous solution thereby significantly constraining their potential for in vivo applications.

Occurrence, spatial-seasonal variation and air-soil exchange of traditional and novel organochlorine pesticides across 30° latitude in Eastern China: Old tales and new realities.

J Hazard Mater

February 2025

International Joint Research Center for Persistent Toxic Substances (IJRC-PTS), State Key Laboratory of Urban Water Resource and Environment, Harbin Institute of Technology, Harbin 150090, China.

While traditional organochlorine pesticides (OCPs) have been phased out under international regulations, novel OCPs are increasingly used as substitutes, however, their environmental behavior was not well clarified. Here, the first comprehensive study on the occurrence, seasonal-spatial variation, and air-soil exchange of both traditional and novel OCPs across a 30° latitudinal gradient (22°N to 52°N) in Eastern China were conducted. Air concentrations of ΣOCPs peaked during summer months, whereas soil concentrations were elevated in winter.

Enhanced Chemiluminescence Induced by Natural Light-Driven MIL-100(Fe)/TiO for Dopamine Detection.

Anal Chem

March 2025

State Key Laboratory of Environmental Chemistry and Eco-Toxicology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, 18 Shuangqing Road, P.O. Box 2871, Beijing 100085, China.

Luminol-based chemiluminescence (CL) systems, as a powerful tool for bioanalysis, are limited owing to their weak CL intensity and self-decomposition of the classic oxidant HO. Herein, we introduced a new luminol CL enhancer, the natural light-driven photocatalyst MIL-100(Fe)/TiO, for the selective determination of dopamine (DA). By employing MIL-100(Fe)/TiO for the first time as an efficient enhancer, the MIL-100(Fe)/TiO-luminol CL intensity was 100 times higher than that of the classical HO-luminol system.

As an important geological environment medium for engineering construction in southwest China, basalt generally contains hidden microcracks at a micro-scale, which leads to significant size effect on its mechanical properties, and relevant research is lacking and unsystematic. A synthetic rock mass model based on the combination of a micro-discrete fracture network method and a finite-discrete element method is used to systematically explore the size effect of the mechanical properties of basalt rock blocks with hidden microcracks. The results showed that: (1) the fracture angle is uniformly distributed, and the fracture length conforms to the logarithmic normal distribution, with an areal fracture intensity P20 of 0.

Tomato yellow leaf curl virus (TYLCV), a devastating pathogen of tomato crops, is vectored by the whitefly , yet the mechanisms underlying TYLVC epidemics are poorly understood. We found that TYLCV triggers the up-regulation of two β-myrcene biosynthesis genes in tomato, leading to the attraction of nonviruliferous . We also identified BtMEDOR6 as a key whitefly olfactory receptor of β-myrcene involved in the distinct preference of MED for TYLCV-infected plants.

Room-temperature sodium-sulfur (Na-S) batteries are emerging as a promising next-generation energy storage technology, offering high energy densities at low cost and utilizing abundant elements. However, their practical application is hindered by the shuttle effect of sodium-polysulfides and the sluggish kinetics of sulfur redox reactions. In this study, we demonstrate a heteronuclear diatomic catalyst featuring Fe and Co bimetallic sites embedded in nitrogen-doped hollow carbon nanospheres (Fe-Co/NC) as an effective sulfur host at the cathode of Na-S batteries.

Background: The mental health of first-generation college students has received much attention from researchers. The dual-factor model of mental health emphasizes the integration of psychopathology and well-being to achieve a comprehensive assessment of mental health. Previous research has focused on the psychopathology and well-being of first-generation college students in isolation while ignoring the overall mental health development.
