Direct and rapid detection of serum amino acid and monoamine neurotransmitters to assist the diagnosis of panic disorder

Science China Chemistry 2025年第01期 377-384页

作者： Shiwen Liu xuerui Wan Meng Zhao Jiaqi Wang Weilan Wu Linlin You Yonggui Yuan Qian xu Rong Gao Key Laboratory of Environmental Medicine Engineering Ministry of Education School of Public Health Southeast University Key Laboratory of Modern Toxicology of Ministry of Education Department of Hygienic Analysis and Detection School of Public HealthNanjing Medical University Department of Psychosomatics and Psychiatry Zhongda Hospital School of Medicine Southeast University

The measurement of amino acid and monoamine neurotransmitters（NTs） in serum plays a central role in the identification and monitoring of clinical panic disorder（PD）. However, the strong polarity and chemical heterogeneity of NTs make direct extraction and rapid detection extremely challenging. Herein, we developed a strategy that integrated solid phase extraction based on magnetic Fe3O4coated with polydopamine（Fe3O4@PDA） and direct analysis of mass spectrometry in real time（DART-MS） for quantification of 10 NTs. We systematically investigated the optimal conditions of this strategy to achieve good accuracy and precision. Compared with existing magnetic solid phase extraction methods for NTs detection in biological samples, this strategy could adsorb more targets while having similar adsorption efficiencies, and the total process time was reduced by an average of 69.42%. We rapidly determined the metabolic abnormality of 6 types of NTs in the serum of PD patients and demonstrated their diagnostic accuracy. In addition, an outstanding feature of PD in which tryptophan was more metabolized by the KYN pathway and the 5-hydroxytryptamine pathway was inhibited could be elucidated by this strategy. Our results highlighted the potential ability of Fe3O4@PDA coupled with DART-MS to assist in the clinical diagnosis of PD.

Design high-performance narrowband emitters for blue light-emitting diodes through manipulating resonance structure of aromatic heterocycles

引用

Science China Chemistry 2025年

作者： Yue Yu Lei xu Wenle Tan Yuyu Pan Jiyin Xiao Bohan Wang Guangjun Tian Yuguang Ma Lei Ying Institute of Polymer Optoelectronic Materials and Devices Guangdong Basic Research Center of Excellence for Energy and Information Polymer Materials State Key Laboratory of Luminescent Materials and Devices South China University of Technology School of Petrochemical Engineering Shenyang University of Technology Key Laboratory for Microstructural Material Physics of Hebei Province School of Science Yanshan University

Narrowband light-emitting materials play critical roles in improving the color gamut and energy consumption of electroluminescence. Herein we demonstrated that by regulating the ground state resonance structure form of emitters with polycyclic aromatic heterocycles, the high-energy vibration of the C–C bond can be effectively suppressed, resulting in narrow emission like classical cyanine dyes. The designed compounds consist of twist and planar conformation, while having differences in the orientation of the positioning electron-donating(nitrogen) and electron-accepting(carbonyl) groups in the polycyclic aromatic hydrocarbon skeleton. The resulting compound Ac-Ph-Ac with a dominated zwitterionic resonance structure exhibits a relatively wide electroluminescent profile with the full width at half maximum(FWHM) of 42 nm and moderate device performance. In contrast, the “soliton transition” of 2AcPh based on the cyanine limit character effectively suppresses C–C stretching vibration in the polycyclic aromatic heterocycle skeleton, leading to a narrow electroluminescent profile with FWHM of 30 nm(0.16 eV)associated with an impressively high external quantum efficiency of 28.52%, which is among the highest efficiencies of so far reported non-sensitized organic light-emitting diodes.

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.

Ni-catalyzed cross-electrophile alkyl-alkyl coupling reactions

引用

Science China Chemistry 2025年

作者： Li-xu You Lan Tian Chun-Ling Guo Shun-Xi Li Yu-Cheng Liu Yu-Long Li Wei Shu College of Chemistry and Environmental Engineering Key Laboratory of Green Catalysis of Higher Education Institutes of Sichuan Sichuan University of Science and Engineering Guangming Advanced Research Institute Shenzhen Grubbs Institute Department of Chemistry and Guangdong Provincial Key Laboratory of Catalysis Southern University of Science and Technology

Introducing saturated carbon-carbon bonds into organic molecules significantly increases the three-dimensional configuration,thus altering the physical and chemical properties as well as the functions of molecules. Transition-metal-catalyzed carboncarbon cross-couplings represent one of the most straightforward, efficient and modular alternatives to build saturation in a single step. However, the efficient construction of alkyl-alkyl bonds remains a formidable challenge due to the precise manipulation of multiple alkyl metallic intermediates as well as associated competitive side reactions and selectivity control. Over the past years, Ni-catalyzed cross-coupling under reductive conditions has gained more and more attention for alkyl-alkyl crosscoupling partially attributing to the low-valent state of metal centers under reducing conditions, which suppresses the competitive β-hydride elimination process, thus facilitating the formation of alkyl-alkyl bonds. In this review, the initiative and progress of Ni-catalyzed cross-electrophile alkyl-alkyl cross-coupling, including the efforts in racemic and enantioselective formation of alkyl-alkyl bonds, have been summarized and discussed. Moreover, the challenges and further opportunities in this area have also been discussed.

海上风机是低碳可持续能源的重要战略选择之一,其地震安全性问题是急需解决的重要课题。将近海单桩式风机三维地震响应问题看作波动散射问题,结合人工边界条件实现海域场地的波动输入,并基于广义饱和多孔介质统一计算框架,发展了一套海水-饱和海床-风机耦合作用高效分区分析方法,实现了综合考虑土-结构相互作用效应和流固耦合效应的近海单桩式风机三维地震响应分析,并分析了海水深度、海床波速和地震波入射角度对近海单桩式风机地震响应的影响。分析结果表明,海水深度和海床剪切波速的变化,一方面会改变自由场,另一方面会改变海域场地-风机体系的自振特性,从而影响风机结构的地震反应。当海水增加到某深度时,体系自振频率与地震波输入频率接近时,风机的地震响应会急剧增大;海床剪切波速对塔底弯矩的影响要比对位移的影响大;当入射角度增大时,塔顶水平向位移和加速度以及塔底弯矩均有不同程度的减小,塔顶竖向位移和加速度均有不同程度的增大。本文没有考虑海床和风机的非线性,考虑非线性时的影响规律需进一步研究。

20世纪三四十年代,中国马克思主义史学形成了一种新经世致用论。这种新经世致用论以马克思主义“科学性与革命性相统一”的原则为指导,是对传统经世致用论批判与继承的产物,具体表现为史学求真与致用的统一,体现了马克思主义的实践理性精神。马克思主义与中国传统文化都有实践理性精神,而传统经世致用思想则为马克思主义史家新经世致用论提供了历史解释的视域。马克思主义史家虽然认为革命性是以科学性为基础的,但往往为了革命性而忽视科学性。故史学要真正做到经世致用,必须以尊重史学科学性为前提。
