Rare earth metal-organic frameworks (RE-MOFs) have drawn wide attention owing to diverse network structures and various application ***,due to the unpredictable formation of the nodes,it is still challenging to design novel RE-MOFs.A novel versatile strategy was developed employing a RE-acetate complex (RE2(CH3COO)6·4H2O) as a precursor to construct RE-MOFs.2D RE-MOFs (RE-DBP) and 3D RE-MOFs (RE-TCPP) could be obtained by using dicarboxylic porphyrin ligands H2DBP and tetracarboxylic porphyrin ligands H2TCPP,*** RE-MOFs were further synthesized to verify the universality of the *** crystalline RE-MOFs could also be prepared at room temperature via the developed strategy,which could significantly promote large-scale preparation and practical application of *** proof of the concept,the performance of porphyrin-based RE-MOFs was investigated in the photocatalytic cycloaddition of CO2with *** the RE-DBP(Co) MOFs,Tb-DBP(Co) exhibited the best photocatalytic performance,which was also greater than that of the corresponding 3D MOF Tb-TCPP(Co) due to the optimal 2D structure and thus the accelerated photogenerated charge separation and transfer *** work not only provides a novel versatile strategy to design and develop RE-MOFs,but also proposes a promising approach for the potential bulk production of RE-MOFs at room temperature.

An Additional Harmonic Current Based Line Protection Method of Active Distribution Network

Zhongguo Dianji Gongcheng Xuebao/Proceedings of the Chinese Society of Electrical Engineering 2025年第4期45卷 1409-1423页

作者： deng, jinglei Yao, Liangzhong Xu, jian cheng, Fan Mao, Beilin Chen, Rusi School of Electrical Engineering and Automation Wuhan University Hubei Province Wuhan 430072 China Electric Power Research Institute of Hubei Electric Power Company Hubei Province Wuhan 430077 China

With the penetration of inverter-interfaced distributed generators (IIDGs) raised, the fault characteristics of distributed network have also changed. Affected by the current limiting of power electronics and converter control strategies, the amplitude of fault current is weakened and the characteristics of fault become complex, rendering traditional protection schemes potentially. Hence, this paper proposes a line protection scheme of distribution network based on additional harmonic current. Based on the flexible and controllable characteristics of the IIDGs, the proposed method actively injects a harmonic current signal into the protection system after a fault by changing the amplitude limiting control of IIDG. Meanwhile, considering the influence of this harmonic signal on the control of IIDG, a corresponding filter is designed. Further, a new protection criterion is constructed based on the amplitude of this harmonic current signal and its phase relationship with the protection positive sequence measurement voltage. A 10 kV active distribution network case study is simulated in PSCAD/EMTDC, and the results verify that the proposed protection scheme can operate correctly and rapidly under both symmetrical and asymmetrical faults. ©2025 *** ***. 1409.

Traceability is the fundamental premise of all metrological activities. The establishment of a traceability chain characterized by a shortened structure, while simultaneously enabling on-site traceability, represents a key trend in the advancement of metrology. This study explores the periodic accuracy and overall uniformity of self-traceable gratings, employing multilayer film gratings with a nominal period of 25.00 nm as the medium. We present a comparative analysis of measurement capabilities in a self-traceable grating calibration system characterized by a ‘top-down’ calibration approach and a Si lattice constant calibration system characterized by a ‘bottom-up’ calibration approach. The results indicate that the values obtained for the multilayer film grating periods, calibrated using the self-traceable grating system, are 24.40 nm with a standard deviation of 0.11 nm. By comparing with the values derived from the Si lattice constant, which yield 24.34 nm with a standard deviation of 0.14 nm, the validity and feasibility of the self-traceable calibration system are confirmed. This system extends and complements existing metrological frameworks, offering a precise pathway for traceability in precision engineering and nanotechnology research.
