Introduction: According to career construction theory, middle school students are in a critical phase of growth and exploration that requires self-reflection on their interests, values, and aspirations. Career adaptability is a key indicator of career development for middle school students and a crucial ability for achieving career success. Research indicates that many Chinese middle school students face significant hurdles in their career development, including a lack of motivation, limited self-awareness, and unclear career trajectories.

Objective: To identify the potential metabolic biomarkers of fluorosis and the pathogenesis of fluorosis.
Methods: Sprague Dawley rats in this study were randomly divided into fluoride exposure and control groups. In the fluoride exposure group, six offspring rats without dental fluorosis were defined as group A, and six offspring rats with dental fluorosis were defined as group C.
The demand for miniaturized and integrated multifunctional devices drives the progression of high-performance infrared photodetectors for diverse applications, including remote sensing, air defense, and communications, among others. Nonetheless, infrared photodetectors that rely solely on single low-dimensional materials often face challenges due to the limited absorption cross-section and suboptimal carrier mobility, which can impair sensitivity and prolong response times. Here, through experimental validation is demonstrated, precise control over energy band alignment in a type-II van der Waals heterojunction, comprising vertically stacked 2D TaNiSe and the topological insulator BiSe, where the configuration enables polarization-sensitive, wide-spectral-range photodetection.

Therefore, it is necessary to improve the heat dissipation capacity and light utilization efficiency of the color converter through appropriate microstructural adjustments. In this study, what we believe to be a novel laminated structure consisting of AlO and YAG:Ce was designed and fabricated for transmissive laser lighting.

Compared with traditional onsite construction, prefabricated construction has a more complex working environment, resulting in more safety risks. While cognitive failure has been identified as a primary cause of intentional unsafe behaviors, there remains a lack of knowledge on the formation mechanism underlying intentional unsafe behaviors among workers in precast construction. Using the Theory of Planned Behavior and the risk preference variable, this study constructs a theoretical model for intentional unsafe behaviors of precast construction workers.

Polyacrylonitrile/TiCTMXene/silver nanoparticles fiber membranes with different silver nanoparticles contents and thickness of porous structure have been successfully prepared by electrospinning. Through the measurement of terahertz time domain spectrum, the shielding effect of the fiber membrane with 1% silver nanoparticles content can reach up to 12 dB. Moreover, the thickness of the spinning fiber membranes is controlled by adjusting the spinning time, so as to better analyze the influence of the thickness of the shielding performance in terahertz band.
