Abstract

PEO-based solid polymer electrolytes are considered as a promising solid electrolyte in the field of solid-state lithium batteries.PEO/LiClO4 solid polymer electrolyte(SPE) was prepared through electrostatic spinning technology, in order to meet the demand of industrial production. The effects of spinning voltage, spinning solution concentration and lithium salt content on the morphology and diameter of the fiber were studied.The morphology of SPE fiber was observed by scanning electron microscope and the diameter of SPE fiber was analysed by Image J.Furthermore, the composition, structure and properties of solid polymer electrolyte fiber membranes prepared by electrospinning were studied by DSC, XRD, FTIR-ATR and tensile testing.The results show that the PEO/LiClO4 solid polymer electrolyte membrane prepared by electrostatic spinning method has good fiber morphology, when the spinning voltage is 15 kV, and the concentration of PEO/LiClO4 spinning solution is 6%, and the molar ratio ([EO]: [Li+]) is 10:1.Meanwhile, the average diameter of the fibers is 557 nm, giving relatively uniform distribution.When[EO]: [Li+]=10:1, the melting point of PEO in the SPE fiber membrane is only 53.8℃, with the crystallinity as low as 18.9%. And the ionic conductivity of the prepared SPE exhibits as high as 5.16×10-5 S·cm-1 at 30℃.Moreover, the prepared electrospun SPE has good electrochemical stability and interfacial stability.

Subjects
Environmental sciences, GE1-350
Abstract

Based on Innojoy patent search engine, this paper analyzes the patent type, technical fields, innovation activity, life cycle and patent value of green building in China. The development trend of green building in China is summarized. Suggestions were put forward to promote the development of China’s green building industry. It is found that the overall development trend of China’s green building is good, and it is in the growth stage of the technology life cycle, and the development potential is huge. Green building gradually runs through the whole process of construction, and the application scope continues to expand. Technological innovation is the core driving force for the development of green building.

180. The effects of coronavirus news on travel and leisure stocks: Evidence from the NARDL model

Abstract

This study employs the NARDL model to investigate the asymmetric effects of COVID-19 news on the return and volatility of travel and leisure stocks in both the United States and the global context. Our findings reveal distinct longand short-term impacts of COVID-19 news on these stocks, exhibiting asymmetry and lag effects. Various types of news, including panic-inducing reports, entity-related coronavirus news, and misleading information, contribute to adjustments in travel and leisure stock returns over the long term. Notably, panic-inducing news has a more pronounced long-term impact on stock volatility compared to a higher volume of news sources reporting coronavirus-related information in similar situations. We argue that regulatory bodies can influence the stock market by ensuring the accuracy and reliability of news content.

184. Penalized-Likelihood Reconstruction with High-Fidelity Measurement Models for High-Resolution Cone-Beam Imaging

Abstract

We present a novel reconstruction algorithm based on a general cone-beam CT forward model which is capable of incorporating the blur and noise correlations that are exhibited in flat-panel CBCT measurement data. Specifically, the proposed model may include scintillator blur, focal-spot blur, and noise correlations due to light spread in the scintillator. The proposed algorithm (GPL-BC) uses a Gaussian Penalized-Likelihood objective function which incorporates models of Blur and Correlated noise. In a simulation study, GPL-BC was able to achieve lower bias as compared to deblurring followed by FDK as well as a model-based reconstruction method without integration of measurement blur. In the same study, GPL-BC was able to achieve better line-pair reconstructions (in terms of segmented-image accuracy) as compared to deblurring followed by FDK, a model based method without blur, and a model based method with blur but not noise correlations. A prototype extremities quantitative cone-beam CT test bench was used to image a physical sample of human trabecular bone. These data were used to compare reconstructions using the proposed method and model based methods without blur and/or correlation to a registered {\mu}CT image of the same bone sample. The GPL-BC reconstructions resulted in more accurate trabecular bone segmentation. Multiple trabecular bone metrics, including Trabecular Thickness (Tb.Th.) were computed for each reconstruction approach as well as the {\mu}CT volume. The GPL-BC reconstruction provided the most accurate Tb.Th. measurement, 0.255 mm, as compared to the {\mu}CT derived value of 0.193 mm, followed by the GPL-B reconstruction, the GPL-I reconstruction, and then the FDK reconstruction (0.271 mm, 0.309 mm, and 0.335 mm, respectively).
