Journal of Energy Chemistry 2025年第1期100卷 481-497页

作者： Wei Song Penggao liu Xinyue Chen Ting Wang Chunrong He rui Hao Kaiyu liu State Key Laboratory of Chemistry and Utilization of Carbon Based Energy Resources College of Chemistry Xinjiang University College of Chemistry and Chemical Engineering Henan Polytechnic University Hunan Provincial Key Laboratory of Chemical Power Sources College of Chemistry and Chemical Engineering Central South University

Coal direct liquefaction technology is a crucial contemporary coal chemical technology for efficient and clean use of coal resources. The development of direct coal liquefaction technology and the promotion of alternative energy sources are important measures to guarantee energy security and economic security. However, several challenges need to be addressed, including low conversion rate, inadequate oil yield, significant coking, demanding reaction conditions, and high energy consumption. Extensive research has been conducted on these issues, but further exploration is required in certain aspects such as pyrolysis of macromolecules during the liquefaction process, hydrogen activation, catalysts' performance and stability, solvent hydrogenation, as well as interactions between free radicals to understand their mechanisms better. This paper presents a comprehensive analysis of the design strategy for efficient catalysts in coal liquefaction, encompassing the mechanism of coal liquefaction, catalyst construction,and enhancement of catalytic conversion efficiency. It serves as a comprehensive guide for further research endeavors. Firstly, it systematically summarizes the conversion mechanism of direct coal liquefaction, provides detailed descriptions of various catalyst design strategies, and especially outlines the catalytic mechanism. Furthermore, it addresses the challenges and prospects associated with constructing efficient catalysts for direct coal liquefaction based on an understanding of their action mechanisms.

Design and characterization study of dual D-shaped no-core fiber based SPR sensor for refractive index and temperature measurement

引用

Optoelectronics Letters 2025年

作者： liu Yinggang Li rui Li Fei Xu Xinyi Zhou rui Shaanxi Engineering Research Center of Oil and Gas Resource Optical Fiber Detection & Shaanxi Key Laboratory of Measurement and Control Technology for Oil and Gas wells， Xi'an Shiyou University

To address the issue of temperature cross-sensitivity in refractive index （RI） measurement， a fiber-optic Surface Plasmon Resonance （SPR） sensor based on dual D-shaped no-core fiber （NCF） is proposed and designed. The sensor mainly consists of D-shaped NCF， Ag/Fe2O3composite film， and polydimethylsiloxane （PDMS）， where the silver and Fe2O3are successively coated on both D-shaped surfaces of NCF to generate SPR and enhance the oxidation resistance. The layer of PDMS coated on one D-shaped surface acts as a tunable ambient medium sensing the temperature variation and affecting the transmission spectrum of the sensor. Since the surface plasmon waves are excited in the two D-shaped surfaces with different films， the two RI and temperature-dependent spectral resonance peaks with different wavelengths will be produced. Research results demonstrate that the two peaks’ wavelengths have different responses to the variations of ambient RI and temperature. In the refractive index range of 1.36-1.376 and temperature range of 10-100 °C， the RI and temperature sensitivities reach to 5000 nm/RIU and -0.546 nm/°C， respectively. With the sensitivity coefficient matrix， simultaneous measurement of refractive index and temperature can be realized， and the corresponding accuracy is superior to 0.4×10-5RIU and 0.037°C.

Tunable non-Markovian and quantum coherence in the single-qubit dephasing noise channel

引用

Science China(Physics,Mechanics & Astronomy) 2025年

作者： Na-Na Zhang Chao-Yi Wu Xu Zhou Qi-Yuan liu Cheng-Ge liu Yong-rui Guo Ren-Pu Li School of Optoelectronic Engineering Chongqing University of Posts and Telecommunications Department of Physics Applied Optics Beijing Area Major Laboratory Beijing Normal University

In this paper, we construct a single-qubit dephasing noise channel based on the nuclear magnetic resonance（NMR） system by employing the bath-engineering technology, and achieve the construction of the tunable non-Markovian environment in the dephasing noise channel. Our findings indicate that for the single-qubit system, the transition of system dynamics from Markovian to non-Markovian can be achieved by adjusting the base frequency of the noise power spectrum. However, the base frequency corresponding to this phase transition point is not fixed, and there is a certain relationship between it and the total evolution time of the single-qubit system. Through our research, we discovered a fundamental relationship: if the single-qubit system dynamics undergoe a transition from Markovian to non-Markovian at ω0within 0-2t ms, shortening the evolution time to 0-t ms results in an increase of the phase transition point to 2ω0. This insight offers crucial guidance for artificially crafting non-Markovian environments across arbitrary time scales in single-qubit systems, and it is not limited by the type of noise. Apart from system dynamics, quantum coherence is also a focal point of our research. We find that when the system dynamics exhibit non-Markovian behavior, the quantum coherence of the single-qubit system experiences revivals. Notably, the timing of these coherence revivals aligns with the instants of the non-Markovianity enhancement. Therefore, our research also serves as a pivotal foundation for the artificial manipulation and realization of quantum coherence revivals within diverse single-qubit systems.

为探究不同时空尺度下不同湖泊类型土地利用对水质的影响差异,以四川省自贡市富顺西湖(河成湖)和云南省腾冲市青海湖(火山湖)为研究对象,提取6个空间尺度(50、60、70、80、90、100 m湖岸带缓冲区)的景观格局指数,结合雨季(2022年7月)和旱季(2023年4月)湖泊水质参数,采用冗余分析法定量探究不同时空尺度下土地利用对两类湖泊水质影响的差异性。结果表明:(1)富顺西湖与腾冲青海湖水质参数季节性差异显著,雨季水质优于旱季,两个湖泊水环境质量存在显著差异,腾冲青海湖水环境质量优于富顺西湖,腾冲青海湖符合地表水环境Ⅱ类、Ⅲ类水质标准,富顺西湖达到Ⅳ类、Ⅴ类水质标准。(2)富顺西湖在旱季和50~60 m湖岸带缓冲区尺度下土地利用参数对水质变量的解释率最大,腾冲青海湖在雨季和60 m湖岸带缓冲区尺度下土地利用参数对水质变量的解释率最大。(3)土地利用指数对两类湖泊水质的影响各不相同。富顺西湖流域内斑块密度、景观形状指数和聚合度指数与多数水质指标呈正相关,“源”景观聚集程度和破碎化程度高会加剧对水质的威胁。腾冲青海湖流域内林地面积占比和聚合度指数对水质具有正效应,能够改善水环境质量;斑块指数和景观形状指数值的增加会加剧斑块破碎化,导致水质恶化。本研究基于不同时空尺度对土地利用与两类湖泊水质关系的差异性进行深入探讨,指导不同类型湖泊的区域规划与管理,为湖泊环境质量评价及保护和制定针对性的湖泊缓冲带设置、生态修复等策略提供科学依据,进而促进湖泊水质安全和水资源可持续利用。
