| 1 | Acupuncture preconditioning protects hippocampal neurons from transient ischemia/reperfusion injury显示文摘The present study established a model of brain ischemia in aged rats using four-vessel occlusion.We observed hippocampal CA1 neuronal apoptosis and apoptosis-mediated protease caspase-3 expression following preconditioning of electroacupuncture at Baihui(GV 20).Our results showed that the number of hippocampal CA1 normal neurons was decreased,and degenerated neurons were increased 12 hours to 3 days following cerebral ischemia/reperfusion.The number of hippocampal CA1 apoptotic neurons and caspase-3-positive neurons in rats with cerebral ischemia/reperfusion injury was significantly decreased following acupuncture preconditioning.Acupuncture preconditioning protects aged rats against ischemia/reperfusion injury by regulating caspase-3 protein expression. | Mingshan Wang Haipeng Zhou Fei Shi Shilong Ma Yanlin Bi Yuqiu Liu Hong Liu Haiou Li | 2011 | Neural Regeneration Research2011，6，15： | 12 |
| 2 | Polarized holographic lithography system for high-uniformity microscale patterning with periodic tunability显示文摘Periodic microscale array structures play an important role in diverse applications involving photonic crystals and diffraction gratings.A polarized holographic lithography system is proposed for patterning high-uniformity microscale two-dimensional crossed-grating structures with periodic tunability.Orthogonal two-axis Lloyd’s mirror interference and polarization modulation produce three sub-beams,enabling the formation of two-dimensional crossed-grating patterns with wavelength-comparable periods by a single exposure.The two-dimensional-pattern period can also be flexibly tuned by adjusting the interferometer spatial positioning.Polarization states of three sub-beams,defining the uniformity of the interference fringes,are modulated at their initial-polarization states based on a strict full polarization tracing model in a three-dimensional space.A polarization modulation model is established considering two conditions of eliminating the unexpected interference and providing the desired identical interference intensities.The proposed system is a promising approach for fabricating high-uniformity two-dimensional crossed gratings with a relatively large grating period range of 500–1500 nm.Moreover,our rapid and stable approach for patterning period-tunable two-dimensional-array microstructures with high uniformity could be applicable to other multibeam interference lithography techniques. | Gaopeng Xue Qihang Zhai Haiou Lu Qian Zhou Kai Ni Liyu Lin Xiaohao Wang Xinghui Li | 2021 | Microsystems & Nanoengineering2021，7，2： | 2 |
| 3 | Precisely installing gold nanoparticles at the core/shell interface of micellar assemblies of triblock copolymers显示文摘Two reduction-cleavable ABA triblock copolymers possessing two disulfide linkages,PMMA-ssPMEO_3MA-ss-PMMA and PDEA-ss-PEO-ss-PDEA were synthesized via facile substitution reactions from homopolymer precursors,where PMMA,PMEO_3MA,PDEA,and PEO represent poly(methyl methacrylate),poly(tri(ethylene glycol) monomethyl ether methacrylate,poly(2-(diethylamino)ethyl methacrylate),and poly(ethylene oxide),respectively.Spherical micelles were obtained through supramolecular self-assembly of these two triblock copolymers in aqueous solutions.The resultant micelles with abundant disulfide bonds could serve as soft templates and precisely accommodate gold nanoparticles in the core/shell interface as a result of the formation of Au-S bonds. | Kangning Zhu Zhiyuan Zhu Haiou Zhou Jingyan Zhang Shiyong Liu | 2017 | Chinese Chemical Letters2017，28，6： | 2 |

| 9 | An Innovative Finite Element Geometric Modeling of Single-Layer Multi-Bead WAAMed Part显示文摘Finite element (FE) coupled thermal-mechanical analysis is widely used to predict the deformation and residualstress of wire arc additive manufacturing (WAAM) parts. In this study, an innovative single-layermulti-bead profilegeometric modeling method through the isosceles trapezoid function is proposed to build the FE model of theWAAMprocess. Firstly, a straight-line model for overlapping beads based on the parabola function was establishedto calculate the optimal center distance. Then, the isosceles trapezoid-based profile was employed to replace theparabola profiles of the parabola-based overlapping model to establish an innovative isosceles trapezoid-basedmulti-bead overlapping geometric model. The rationality of the isosceles trapezoid-based overlapping model wasconfirmed by comparing the geometric deviation and the heat dissipation performance index of the two overlappingmodels. In addition, the FE-coupled thermal-mechanical analysis, as well as a comparative experiment of thesingle-layer eight-bead deposition process show that the simulation results of the above two models agree with theexperimental results. At the same time, the proposed isosceles trapezoid-based overlappingmodels are all straightlineprofiles, which can be divided into high-quality FE elements. It can improve the modeling efficiency andshorten the simulation calculation time. The innovative modeling method proposed in this study can provide anefficient and high-precision geometricmodelingmethod forWAAMpart FE coupled thermal-mechanical analysis. | Xiangman Zhou Jingping Qin Zichuan Fu Min Wang Youlu Yuan Junjian Fu Haiou Zhang Seyed Reza Elmi Hosseini | 2024 | Computer Modeling in Engineering & Sciences2024，138，3： | 0 |
| 10 | Reasonable start time of carbon dioxide injection in enhanced coalbed methane recovery involving thermal-hydraulic-mechanical couplings显示文摘Injection of gas (CO_(2)) into coal seams is an effective method to benefit from both CO_(2) geological storage and coalbed methane recovery. Based on the dual pore structure of coal mass, and the Weibull distribution of fracture permeability, a menmal-hydraulic-mechanical (THM) coupling mathematical model is proposed involving the non-isothermal adsorption of binary gases, dynamic gas diffusion between matrix and fractures, multiphase seepage, coal deformation, heat conduction and heat convection. This mathematical model is applied to study the process of CO_(2)-enhanced coalbed methane recovery (CO_(2)-ECBM). Results show that the CH4 content of CO_(2)-ECBM in coal seam decreases significantly when compared with that of regular drainage, and decreases rapidly in the early stage but slowly in the later stage. Coal seam permeability evolution is triggered by changes in gas adsorption/desorption, temperature and effective stress. For regular drainage, the early permeability shows a decreasing trend dominated by the increase of effective stress, while the later permeability shows an increasing trend dominated by the CH4 desorption caused shrinkage of coal matrix. For CO_(2)-ECBM, the permeability in coal seam generally shows a downward trend due to both matrix swelling induced by gas adsorption and thermal expansion, particularly near injection well. There appears an increased and delayed peak production rate of CH4. The CH4 production rate of CO_(2)-ECBM is always higher than that of regular drainage. The CH4 cumulative production and CO_(2) cumulative storage linearly increase with time, and the CH4 cumulative production of CO_(2)-ECBM increased by 39.2% in the duration of 5000 d compared with regular drainage. Reasonable CO_(2) injection starting time can overcome the issue of early CO_(2) breakthrough and ineffective increase of CH4 production. In the studied case, the optimal injection starting time is 2500 d. Compared with the simultaneous CH4 extraction and CO_(2) injection, the CH4 cumulative production of optimal time has increased by 30.1%. The research provides a reference for determining the reasonable CO_(2) injection time under similar conditions. | Chaojun FAN Lei YANG Bin XIAO Lijun ZHOU Haiou WEN Hao SUN | 2023 | Frontiers of Earth Science2023，17，3： | 0 |
