Achieving Extraordinary Power Factors in GeTe Epitaxial Films through Carrier Transport Engineering.

GeTe-based films have attracted tremendous attention from the thermoelectric community owing to their excellent thermoelectric performance. It is vital to reduce the hole density and maintain a high carrier mobility for GeTe films; however, this remains a significant challenge. To overcome this drawback, we succeeded in fabricating high-crystalline quality GeTe-based films and remarkably improve their electrical properties using molecular beam epitaxy under a low substrate temperature and optimized Te/GeTe flux ratios.

The Relationship Between Fiber Intake and Gut Bacterial Diversity and Composition During the Third Trimester of Pregnancy.

Background/objectives: High fiber (34-36 g/day) diets are recommended during pregnancy due to inverse associations with constipation and adverse pregnancy health outcomes, including pre-eclampsia and gestational diabetes. However, the mechanism for this protective effect is poorly defined. Fiber may be protective due to its impact on the composition and function of specific bacteria within the pregnancy gut microbiome.

Spatiotemporal Patterns in Production and Consumption of Major Foods in Qinghai, China.

Food security is an important foundation of national security. Since China entered a new era in 2012, the supply of agricultural and animal husbandry products in Qinghai has continuously enhanced. However, the implementation of ecological policies such as Grain for Green and Grassland Ecological Compensation restricted the cultivation and grazing areas.

Degradation Efficiency and Mechanism Exploration of an FeSiB Metallic Glass Cathode in the Electro-Fenton Degradation of p-NP.

Fe-based metallic glass (MG) exhibits excellent performance as a heterogeneous catalyst in degradation but is rarely used as a working electrode in electro-Fenton (EF) systems. We used FeSiB MG as the working electrode to investigate the effect of the EF process on the degradation efficiency of p-nitrophenol (p-NP). The EF system had the highest catalytic efficiency (the reaction rate was 3.

RPT: An integrated root phenotyping toolbox for segmenting and quantifying root system architecture.

The dissection of genetic architecture for rice root system is largely dependent on phenotyping techniques, and high-throughput root phenotyping poses a great challenge. In this study, we established a cost-effective root phenotyping platform capable of analysing 1680 root samples within 2 h. To efficiently process a large number of root images, we developed the root phenotyping toolbox (RPT) with an enhanced SegFormer algorithm and used it for root segmentation and root phenotypic traits.
