We report results on the searches of weakly interacting massive particles (WIMPs) with sub-GeV masses (mχ) via WIMP-nucleus spin-independent scattering with Migdal effects and bremsstrahlung emissions incorporated. Analysis on time-integrated (TI) and annual modulation (AM) effects on CDEX-1B data are performed, with 737.1 kg·day exposure and 160 eVee threshold for TI analysis, 1107.5 kg·day exposure and 250 eVee threshold for AM analysis. The sensitive windows in mχare expanded by an order of magnitude. New limits on σSIχNat 90% confidence level at mχ∼ 0.05-0.18 GeV/c2and 0.075-3.0 GeV/c 2in the TI and AM analysis are derived, respectively. Copyright © 2019, The Authors. All rights reserved.

IOP Conference Series: Earth and Environmental Science 2019年第1期257卷

作者： Xiaojuan Wu Ling He Danhui Gao Yuanyuan Zhu Associate professor School of Automation Engineering University of Electronic Science and Technology of China Chengdu China Student School of Automation Engineering University of Electronic Science and Technology of China Chengdu China Lecturer Department of biology and chemical engineering ZhiXing College of HuBei University Wuhan China

For solid oxide fuel cell (SOFC) development, maximizing its electrical efficiency and minimizing its cost are two important optimization objects. A new optimization strategy is proposed in this work, which can maximize the SOFC electrical efficiency and minimize the cost in the case of an air leakage fault. The proposed optimization method involves a fault diagnosis module, a switching module and two backup optimizers. The fault diagnosis part is employed to identify the SOFC current fault type, and the switching module is used to select the appropriate backup optimizer. For the efficiency and cost are two conflicting objectives, the multi-objective optimization strategy based on a non-dominated sorting particle swarm optimization algorithm is applied to determine the trade-off solutions. The optimization results show the proposed method can achieve the maximum efficiency and the minimum cost in the case of SOFC normal, and even in the air leakage fault.

Earthquake engineering and engineering Vibration 2016年第4期15卷 657-672页

Orthotropic membrane components and structures are widely used in building structures, instruments and meters, electronic engineering, space and aeronautics, etc., because of their light weights. However, the same lightweight combined with low stiffness make membranes prone to vibration under dynamic loads, and in some cases the vibration may lead to structural failure. Herein, the undamped nonlinear vibration response of pretension rectangular orthotropic membrane structures subjected to impact loading is studied by analytical and numerical methods. The analytical solution is obtained by solving the governing equations by the Bubnov-Galerkin method and the Lindstedt-Poincare perturbation method. Numerical analysis has also been carried out based on the same theoretical model. The analytical and numerical results have been compared and analyzed, and the influence of various model parameters on membrane vibration discussed. The results obtained herein provide some theoretical basis for the vibration control and dynamic design of orthotropic membrane components and structures.

We present the constraints on the effective kinetic mixing parameter κ of dark photon with two p-type point-contact germanium detectors of CDEX-10 experiment at the China Jinping Underground Laboratory. We determine the exclusive limits on the κ of solar dark photon from the 205.4 kg×day exposure at 90% confidence level, probing new parameter space at masses of 10 to 300 eV in direct detection experiments. Considering dark photon as a dark matter candidate, the constraints for dark photon masses within 0.1-4.0 keV are set from the 449.6 kg×day data, with a minimum of 1.3×10−15 for 200 eV dark photon dark matter at 90% confidence level.

We present the improved constraints on couplings of solar axions and more generic bosonic dark matter particles using 737.1 kg-days of data from the CDEX-1B experiment. The CDEX-1B experiment, located at the China Jinping Underground Laboratory, primarily aims at the direct detection of weakly interacting massive particles using a p-type point-contact germanium detector. We adopt the profile likelihood ratio method for analysis of data in the presence of backgrounds. An energy threshold of 160 eV was achieved, much better than the 475 eV of CDEX-1A with an exposure of 335.6 kg-days. This significantly improves the sensitivity for the bosonic dark matter below 0.8 keV among germanium detectors. Limits are also placed on the coupling gAe −11 from Compton, bremsstrahlung, atomic-recombination and de-excitation channels and gANeff ×gAe −17 from a 57Fe M1 transition at 90% confidence level.

We have developed a low-energy electron recoil (ER) calibration method with 220Rn for the PandaX-II detector. 220Rn, emanated from natural thorium compounds, was fed into the detector through the xenon purification system. From 2017 to 2019, we performed three dedicated calibration campaigns with different radon sources. The detector response to α, β, and γ particles was studied, with focus on low energy ER events. The amount of radioactive background, including 222Rn and thorium particulate, was measured and found to be manageable in two sources. The background contribution from 214Pb was also measured for the first time in PandaX-II with help from a 222Rn injection. Copyright © 2020, The Authors. All rights reserved.

We report a search for new physics signals using the low energy electron recoil events in the complete data set from PandaX-II, in light of the recent event excess reported by XENON1T. The data correspond to a total exposure of 100.7 ton-day with liquid xenon. With robust estimates of the dominant background spectra, we perform sensitive searches on solar axions and neutrinos with enhanced magnetic moment. We find that the axion-electron coupling gAe −12 for an axion mass less than 0.1 keV/c2 and the neutrino magnetic moment µν −11µB at 90% confidence level. The observed excess from XENON1T is within our experimental constraints. Copyright © 2020, The Authors. All rights reserved.

We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. Datasets with a total live time of 3.2 yr within a 4.2 yr span are analyzed with analysis threshold of 250 eVee. Limits on WIMP-nucleus (χ-N) spin-independent cross sections as function of WIMP mass (mχ) at 90% confidence level (C.L.) are derived using the dark matter halo model. Within the context of the standard halo model, the 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and 98% C.L., respectively. These results correspond to the best sensitivity at mχ2 among WIMP AM measurements to date. Copyright © 2019, The Authors. All rights reserved.

Bare and polymer coated iron oxide superparamagnetic nanoparticles for effective removal of U (VI) from acidic and neutral aqueous medium

作者： Zhu, Shan Leng, Yangchun Yan, Minhao Tuo, Xianguo Yang, Jianbo Almásy, László Tian, Qiang Sun, Guangai Zou, Lin Li, Qintang Courtois, Jérémie Zhang, Hong College of Nuclear Technology and Automation Engineering Chengdu University of Technology Chengdu61009 China State Key Laboratory Cultivation Base for Nonmetal Composites and Functional Materials Southwest University of Science and Technology Mianyang621010 China Sichuan University of Science and Engineering Zigong643000 China Institute for Solid State Physics and Optics Wigner Research Centre for Physics POB 49 Budapest1525 Hungary Mianyang621999 China

Superparamagnetic γ-Fe2O3nanoparticles (5 nm diameter) were synthesized in water. The bare particles exhibit good colloidal stability at ~ pH 2 because of the strong electrostatic repulsion with a surface charge of +25 m V. The polyacrylic acid (PAA)-coated particles exhibit remarkable colloidal stability at ∼ pH 7 with abundant free carboxyl groups as reactive sites for subsequent functionalization. In this work, we used zeta potential analysis, transmission electron microscopy, small angle X-ray scattering, and Inductively coupled plasma mass spectrometry to investigate the adsorption behavior of U (VI) on bare and coated colloidal superparamagnetic nanoparticles at pH 2 and pH 7. At pH 2, uranyl ion (UO22+) absorbed on the surface of the bare particles with decreasing particle surface charge. This induced particle agglomeration. At pH 7, uranyl ion (UO22+) hydrolyzed and formed plate-like particles of uranium hydroxide that were ∼ 50 nm in diameter. The PAA-coated iron oxide nanoparticles absorbed on the surface of these U (VI) hydroxide plates to form large aggregates that precipitate to the bottom of the dispersion. At both pH 2 and pH 7, the resulting U (VI)/nanoparticle complex can be easily collected and extracted from the aqueous environment via an external magnetic field. The results show that both bare and polymer-coated superparamagnetic γ-Fe2O3nanoparticles are potential absorbents for removing U (VI) from water. Copyright © 2018, The Authors. All rights reserved.
