Boosting the UV-vis-NIR Photodetection Performance of MoS through the Cavity Enhancement Effect and Bulk Heterojunction Strategy.

Navigating more effective methods to enhance the photon utilization of photodetectors poses a significant challenge. This study initially investigates the impact of morphological alterations in 2H-MoS on photodetector (PD) performance. The results reveal that compared to layered MoS (MoS NLs), MoS nanotubes (MoS NTs) impart a cavity enhancement effect through multiple light reflections.

Boosting the Photocatalytic Performance of g-CN through MoS Nanotubes with the Cavity Enhancement Effect.

The development of catalysts with high photon utilization efficiency is crucial for enhancing the catalytic performance of photocatalysts. Graphitic carbon nitride (g-CN) is a prominent material in the field of photocatalysis. However, it still exhibits drawbacks such as low utilization of visible light and severe recombination of photogenerated carriers.

Organic pollutant degradation for micro-molecule product emission over SiO layers-coated g-CN photocatalysts.

In this study, a SiO layer-coated g-CN catalyst was prepared by a sol-gel method to overcome the poor adsorption ability and high recombination rate of charge carriers of pristine g-CN. SEM and TEM images indicated that SiO nanoparticles were coated on the surface of g-CN nanoparticles with a layered structure and the layers were tightly contacted with g-CN. XRD patterns, FTIR spectra, UV-vis spectra and XPS spectra revealed that the structure of g-CN was not destroyed and its photoelectric catalytic properties were not suppressed by the coating of SiO layers.

Two new alkaloids isolated from Turcz.

Two new quinoline alkaloids (-) together with twenty-two known alkaloids (-) were isolated and identified from Turcz. Compounds -, , , -, and were isolated from for the first time. The structures of all compounds were characterised by spectroscopic methods (1D, 2D NMR and HRESIMS).

Mantuoluosides A-H, new steroids isolated from the leaves of Datura stramonium L.

Eight new steroids, designated mantuoluosides A-H (1-8), were obtained from the enrichment of steroids of the Datura stramonium L. using HPD-BJQH macroporous resin. Their respective structures were elucidated based on spectroscopic methods and comparison data with literature.

Spatial Analysis on the Role of Multi-Dimensional Urbanizations in Carbon Emissions: Evidence from China.

Using the panel data of 30 provinces in China from 1997 to 2015, this paper studies the impacts of urbanization on carbon emission. We use the entropy weight method to measure the weight of the indicator to evaluate four-dimensional urbanizations, including population, economic, consumption and living urbanization. In addition, we investigated the spatial correlation of carbon emissions, taking the spatial differences into consideration.
