Abstract

A novel pumped hydro combined with compressed air energy storage ( PHCA) system is proposed in this paper to resolve the problems of bulk energy storage in the wind power generation industry over an area in China, which is characterised by drought and water shortages. Thermodynamic analysis of the energy storage system, which focuses on the pre-set pressure, storage volume capacity, water air volume ratio, pump performance, and water turbine performance of the storage system, is also presented. This paper discovers how such parameters affect the performance of the whole system. The ideal performance of this novel system has the following advantages: a simple, highly effective and low cost structure, which is comparable to the efficiency of a traditional pumped hydro storage system. Research results show a great solution to the current storage constraints encountered in the development of the wind power industry in China, which have been widely recognised as a bottleneck in the wind energy storage industry.

Analysis of a hybrid heat and underwater compressed air energy storage system used at coastal areas

Zhan Liu, Jialu Ding, Xinyu Huang, Zhengguang Liu, Xuewen Yan, Xianglei Liu, Xiaohu Yang

Summary: Offshore wind power has gained attention in recent years for its advantages of high wind speed, constant wind direction, abundant wind energy resources, and sufficient utilization hours. The integration of underwater compressed air energy storage into offshore wind farms has been recognized as one of the most competitive technologies. However, the economics of this storage device become a challenge in shallow-water areas. To address this issue, a hybrid heat and underwater compressed air energy storage system is proposed to integrate with fluctuating renewable energies. The study examines both the thermodynamics and economics of the system under constant or varying power input and finds that the water depth has a significant impact on system behavior. The results demonstrate the greater value of the system integrating with solid thermal energy storage in managing offshore renewable powers. It also suggests that using a larger diameter underwater pipe can improve system performance.

Phase junction crystalline carbon nitride nanosheets modified with CdS nanoparticles for photocatalytic CO2 reduction

Gongjie Chen, Fen Wei, Ziruo Zhou, Bo Su, Can Yang, Xue Feng Lu, Sibo Wang, Xinchen Wang

Summary: Polymeric carbon nitrides, especially the crystalline allotrope known as poly(triazine imide) (PTI), have been found to have great potential for photocatalytic CO2 reduction. However, the poor visible light absorption of pristine PTI significantly hinders its photocatalytic performance. In this study, crystalline carbon nitride nanosheets composed of PTI and melon phase junctions were synthesized via one-pot polycondensation and modified with CdS nanoparticles to create CCN/CdS hybrids with double-junction structures. The resulting CCN/CdS heterostructures demonstrated broad visible-light harvesting, enhanced CO2 adsorption/activation, and improved separation and transfer of photoinduced charges. Thus, the optimized CCN/CdS hybrid exhibited remarkable activity and high stability for photocatalytic CO2-to-CO conversion.

Summary: We report on measurements of sequential Y suppression in Au + Au collisions at RHIC with the STAR detector. The nuclear modification factors (RAA) for Y(1S) and Y(2S) in the 0%-60% centrality class are 0.40 and 0.26, respectively, while the upper limit of the Y(3S) RAA is 0.17. This provides experimental evidence that the Y(3S) is significantly more suppressed than the Y(1S) at RHIC, and the level of suppression for Y(1S) is comparable to that observed at the Large Hadron Collider.

Summary: We report on the production of tritons (t) in Au + Au collisions at midrapidity ( |η| < 0.5) with beam energies of √sNN 7.7-200 GeV. The yield ratio Nt x Np/N2d, which is sensitive to the fluctuation of local neutron density, decreases monotonically with increasing charged-particle multiplicity (dNch/dη) and follows a scaling behavior. Enhancements in the yield ratios are observed in central collisions at 19.6 and 27 GeV, with a combined significance of 4.1 sigma, and are not seen in peripheral collisions or calculations without critical fluctuation. The implications of these results on the QCD phase structure and the production mechanism of light nuclei in heavy-ion collisions are discussed.

Summary: This study presents a low-energy search for the Chiral Magnetic Effect (CME) in Au+Au collisions at RHIC and finds consistency between CME and flow-driven background hypothesis based on the definition of event planes and centrality range. This work opens up a possible roadmap for future CME exploration with high-statistics data from RHIC.

Charged particle therapy for high-grade gliomas in adults: a systematic review

Yuhang Wang, Ruifeng Liu, Qiuning Zhang, Meng Dong, Dandan Wang, Junru Chen, Yuhong Ou, Hongtao Luo, Kehu Yang, Xiaohu Wang

Summary: High-grade gliomas remain difficult to treat despite standard therapy. Charged particle beams, especially carbon ion beams, have the potential to improve treatment outcomes. This systematic review assessed the safety, efficacy, and dosimetry of carbon-ion or proton radiotherapy for high-grade gliomas. The analysis of eleven eligible articles showed that charged particle radiotherapy was effective with manageable side effects. Carbon ion boost appeared to be superior to proton boost, but dose-escalation using proton boost was associated with severe brain necrosis. Further randomized control trials are needed, along with systemic therapeutic options.

How about the evidence assessment tools used in education and management systematic reviews?

Hui Lan, Xuan Yu, Zhe Wang, Ping Wang, Yajia Sun, Zijun Wang, Renfeng Su, Ling Wang, Junxian Zhao, Yue Hu, Shouyuan Wu, Mengjuan Ren, Kehu Yang, Xingrong Liu, Yaolong Chen

Summary: This study aims to examine the usage of evidence assessment tools in systematic reviews of management and education. The results show that only 34.8% of the systematic reviews used evidence assessment tools, with a total of 66 different tools being utilized. "Risk of Bias" and its updated version were the most frequently used tools. The study also highlights the need for improved understanding and reporting of evidence assessment tools among researchers and users.

Squeeze flow of a Maxwell fluid between two parallel disks or two spheres

Zhaolin Zheng, Haiou Xie, Xuedong Chen, Xuhui Liu, Wei Yang, Yong Xu, Wenbin Huang

Summary: In this study, the squeeze flow behavior of an upper convected Maxwell fluid between two rigid disks or spheres was investigated. It was found that the velocity field of the Maxwell squeeze flow between two disks is similar to that of a Newtonian fluid when the Deborah number is low. Based on the Newtonian fluid velocity field, the pressure distribution between two parallel disks was analyzed, and a theoretical model of normal squeeze force was developed. The same method was also used to analyze the interaction between two nearly contacting, arbitrary rigid spheres. Analytical expressions for the pressure distribution and normal squeeze force were obtained, which can be used in the contact model for discrete element simulation of wet particle systems with the Maxwell fluid.
