Unveiling the emission mechanism in analog-doped carbazole-based organic afterglow materials
Abstract Afterglow from purely organic solids has drawn increasing attention over the past decade. In carbazole-based systems, recent studies revised earlier aggregation-state explanations and implicated trace carbazole analog impurities as the origin. However, the widely assumed charge-trapping mechanism cannot account for exponential decay kinetics, lacks robust experimental validation and leaves some photophysical features unexplained.

Thermal conductivity of linear and network polyesters
Keywords polyesters biaxially oriented polymers thermal conductivity anisotropy coefficient of thermal expansion condensation polymerization aliphatic-aromatic polymers temperature-dependent thermal conductivity Introduction The small range of thermal conductivities that is typically found in polymeric materials limits their performance in a variety of applications that require the control of heat transfer.1 Lower thermal conductivity is desirable for creating better thermal insulators and...
Dual Enhancement of *CO Binding and *H Supply by Photothermal Heterojunction Nanosheets toward High-Efficiency CO2 Methanation
Abstract Click to copy section linkSection link copied! Photocatalytic CO2 methanation presents a sustainable route to mitigate greenhouse effect and advance carbon neutrality. However, the pivotal *CO protonation step to *CHO, essential for CH4 formation, is kinetically and thermodynamically disfavored over *CO desorption, limiting the overall efficiency.

A Space-Time Absolute Nodal Coordinate Formulation Cable Element and the Study of Its Accuracy and Efficiency
5. The Simulation and Experimental Verification of the Free Flexible Pendulum The free flexible pendulum serves as a common illustration of ANCF cable for precise validation. This chapter employs a simulation and an experiment to authenticate the two categories of SAC element with consideration to air resistance. For the simulation and experiment, a 0.5-meter gutta-percha cable is utilized in the free-pendulum setup. The characteristics of this cable are presented in Table 9.
Fractional Derivative Viscosity of ANCF Cable Element
Abstract : Typical engineering cable structures, such as high-voltage wire and wire rope, usually bring a damping effect which cannot be ignored due to the technological problems of manufacturing. For such problems, especially the damping of cable structures undergoing large displacement and severe deformation, few studies have been reported in the past. In this work, the fractional derivative viscosity model is introduced into the cables described by the absolute nodal coordinate formulation.
High Serum Iron level is Associated with Increased Mortality in Patients with Sepsis
In this large cohort of ICU patients, a higher serum iron quartile was associated with increased 90-day mortality in patients with sepsis. Furthermore, a dose-response analysis indicated that the risk of death on day 90 increased as the quartiles of serum iron levels upon ICU admission increased. In animal models, bacterial proliferation has been shown to be driven by iron sufficiency and suppressed by iron starvation8,9,10.
Molecular Epidemiology and Mechanism of Sulbactam Resistance in Acinetobacter baumannii Isolates with Diverse Genetic Backgrounds in China
Sulbactam is a plausible option for treating Acinetobacter infections because of its intrinsic antibacterial activity against the members of the Acinetobacter genus, but the mechanisms of sulbactam resistance have not been fully studied in Acinetobacter baumannii. In this study, a total of 2,197 clinical A. baumannii isolates were collected from 27 provinces in China.
