| 1 | Ultrathin, flexible, and high-strength Ni/Cu/metallic glass/Cu/Ni composite with alternate magneto-electric structures for electromagnetic shielding显示文摘Electromagnetic interference(EMI)shielding materials with ultrathin,flexible,superior mechanical and thermal management properties are highly desirable for smart and wearable electronics.Here,ultrathin and flexible Ni/Cu/metallic glass/Cu/Ni(Ni/Cu/MG)multilayer composite with alternate magnetic and electrical structures was designed via facial electroless plating of Cu and Ni on an Fe-based metallic glass.The resultant 0.02 mm-thick Ni/Cu/MG composite displays a superior EMI shielding effectiveness(EMI SE)of 35 dB and a great EMI SE/t of 1750 dB/mm,which is greater than those of composites with monotonous multilayer or homogeneous structures.The improved EMI SE originates from the massive ohmic losses,the enhanced internal reflection/absorption,and the abundant interfacial polarization loss.Particularly,Ni/Cu/MG exhibits a high tensile strength of up to 1.2 GPa and outstanding mechanical stability,enabling the EMI SE remains unchanged after 10,000 times of bending.Moreover,Ni/Cu/MG has excellent Joule heating characteristics and thermal stability,which is very suitable for heating components of wearable hyperthermia devices. | Zenan Ma Jiawei Li Jijun Zhang Aina He Yaqiang Dong Guoguo Tan Mingqiang Ning Qikui Man Xincai Liu | 2021 | Journal of Materials Science & Technology2021,,22: | 3 |
| 2 | The roles of stress state and pre-straining on Swift effect for an extruded AZ31 Mg alloy显示文摘The Swift effect of Mg alloy is sensitive to initial texture.However,dislocation slip is the main deformation mechanism during torsion of Mg alloy.The underlying relation of Swift effect and dislocation slip is still not clarified.The effect of stress state and pre-straining on Swift effect was studied experimentally during free-end torsion for an extruded AZ31 alloy.The free-end torsion was performed with axial tension and compression stress which is lower than yield stress.It is found that the transition of axial deformation from contraction to elongation occurs when the axial stress changes from negative to positive.The pre-dislocations introduced by pre-tension promote axial shortening during torsion.While the pre-twins introduced by pre-compression are inhibition of axial shortening.The change of axial deformation is attributed to competition between twinning and prismatic slip.The axial shortening of extruded Mg alloy is generated by tensile twinning leading to c-axis strain.In contrast,the axial elongation can be generated by the activation of prismatic slip.The magnitude of axial strain generated by twinning is larger than that by prismatic slip.Moreover,the occurrence of detwinning results in axial elongation at low shear strain. | Chong Yang Guoguo Zhu Hui Zhao Yan Peng Baodong Shi | 2023 | Journal of Magnesium and Alloys2023,11,5: | 1 |

| 6 | Magnetic-electric composite coating with oriented segregated structure for enhanced electromagnetic shielding显示文摘Manipulation of the internal architecture is essential for electromagnetic interference(EMI)shielding performance of metal-based coatings,which can address the electromagnetic pollution in large-size,complex geometries,and harsh environments.In this work,oriented segregated structure with conductive networks embedded in magnetic matrix was achieved in Fe-based amorphous coatings via Ni-Cu-P functionalization of(Fe_(0.76)Si_(0.09)B_(0.1)P_(0.05))_(99)Nb_(1)amorphous powder precursors and then thermal spraying them onto aluminum(Al)substrate.Benefiting from the unique magnetic-electric structure,the coating@Al composite delivered prominent EMI shielding performance.The EMI shielding effectiveness(SE)of modified coating@Al composite is~41 dB at 8-12 GHz,doubling the value of Al substrate and is 15 dB greater than that of Ni-Cu-P-free coating@Al composite.Microstructure analysis showed that the introduced Ni−Cu−P insertions forcefully suppress the serious oxidation of the magnetic precursors during thermal spraying and form a dense conductive network in the magnetic matrix.Electron holography observation and electromagnetism simulation clarified that the modified coating can effectively trap and attenuate the incident radiations because of the electric loss from Ni−Cu−P conductive network,magnetic loss from Fe-based amorphous coating,and the electromagnetic interactions in the oriented segregated architectures.Moreover,the optimized thermal isolation and mechanical properties brought by structural improvement enable the coating to shield complex parts in thermal shock and mechanical loading environments.Our work gives an insight on the design strategies for metal-based EMI shielding materials and enriches the fundamental understanding of EMI shielding mechanisms. | Jijun Zhang Zexuan Wang Jiawei Li Yaqiang Dong Aina He Guoguo Tan Qikui Man Bin Shen Junqiang Wang Weixing Xia Jun Shen Xin-min Wang | 2022 | Journal of Materials Science & Technology2022,,1: | 1 |

| 12 | In-situ constructed Ru-rich porous framework on NiFe-based ribbon for enhanced oxygen evolution reaction in alkaline solution显示文摘Exploiting economical and high-efficient electrocatalysts of oxygen evolution reaction(OER)remains urgent in the field of sustainable hydrogen generation by water electrolysis.Ru-and Ir-based materials are benchmark electrocatalysts towards the OER,yet the precious metals are expensive and scarce.Herein,we develop a kind of Ru-doped NiFe-based catalyst with three-dimensional nanoporous surface(NP-Ru_(x)),which fulfils both performance and cost requirements for the OER electrocatalysis.This novel material can directly work as a support-free electrode and exhibits excellent OER performance with an ultralow overpotential of 245 mV at 10 mA cm^(-2) and a small Tafel slope of 15 mV dec^(-1) as well as low charge transfer resistance.The superior performance could be rationalized as follows:(1)Generated Ru-rich nanoporous architecture can not only supply a large number of active sites but also facilitate mass transfer at the electrode/electrolyte interface;(2)Multiple metals(hydro)oxides generated on the surface have the synergistic catalytic effect for the OER;(3)The in-situ generation of(hydro)oxides and the firm bonding of nanoporous layer and the substrate allow for easy electron transfer.These features make NP-Ruxa promising oxygen-evolving electrode material toward water electrolysis. | Guoguo Xi Lei Zuo Xuan Li Yu Jin Ran Li Tao Zhang | 2021 | Journal of Materials Science & Technology2021,,11: | 0 |
| 13 | Efficacy of Ganshuang granules(肝爽颗粒)on non-alcoholic fatty liver and underlying mechanism:a network pharmacology and experimental verification显示文摘OBJECTIVE:To investigate the potential pharmacological mechanisms of Ganshuang granules(肝爽颗粒,GSG)in treating non-alcoholic fatty liver(NAFLD).METHODS:All the active components and targets of GSG were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.Protein-Protein interaction network,Kyoto Encyclopedia of Genes and Genomes and Gene Ontology function annotation of common targets were analyzed to predict the mechanisms of action of GSG in the treatment of NAFLD.Then,the mouse models of NAFLD were constructed in a diet-induced manner and treated with GSG.The levels of interleukin 6(IL-6),tumor necrosis factor-alpha(TNF-α)and phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT)pathway-related proteins in the liver of mice in each group were measured by enzyme linked immunosorbent assay and Western blot,respectively.RESULTS:Network pharmacology revealed a total of 159 potential targets of GSG for the treatment of NAFLD.Functional enrichment analysis indicated that the PI3K/AKT signaling pathway may be involved during GSG treatment of NAFLD.Further experiments showed that the significantly decreased alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase,total cholesterol,triglyceride and low-density lipoprotein cholesterol levels in NAFLD model mice serum after GSG treatment,as well as the expression levels of IL-6 and TNF-αin the liver.Furthermore,drug intervention increased the protein expression levels of phosphorylated-PI3K(P-PI3K)and P-AKT in the liver of the model group mice,and decreased the protein expression level of sterol regulatory element-binding protein 1.CONCLUSION:We found that GSG is effective in treating NAFLD and the potential therapeutic targets may be involved in PI3K/AKT signaling pathway. | ZHI Guoguo SHAO Bingjie ZHENG Tianyan JI Shaoxiu LI Jingwei DANG Yanni LIU Feng WANG Dong | 2024 | Journal of Traditional Chinese Medicine2024,44,1: | 0 |
| 14 | The donor-dependent methoxy effects on the performance of hole-transporting materials for perovskite solar cells显示文摘In this work, a comprehensive study on the deliberate molecular design and modifications of electron donors is carried out to elucidate correlations between the methoxy effects and donor configuration of hole-transporting materials(HTMs). Our initial findings demonstrate the donor-dependent methoxy effects. Photovoltaic performance of the HTM with twisted donor highly depends on the methoxy substituent. In contrast, efficiency’s reliance on methoxy is insignificant for the HTM with planar donor. The HTM(M123) featuring the methoxy–substituted carbazole shows a decent power conversion efficiency of 19.33% due to synergistic effects from both planar structure and methoxy. This work gives a guideline to access HTMs reaching both high-performance and good stability. | Mengyuan Li Jinhua Wua Guoguo Wang Bingxue Wu Zhe Sun Song Xue Qiquan Qiao Mao Liang | 2020 | Journal of Energy Chemistry2020,29,8: | 0 |

| 18 | Soliton microcomb-assisted microring photonic thermometer with ultra-high resolution and broad range显示文摘Whispering gallery mode resonators(WGMRs)have proven their advantages in terms of sensitivity and precision in various sensing applications.However,when high precision is pursued,the WGMR demands a high-quality factor usually at the cost of its free spectral range(FSR)and corresponding measurement range.In this article,we propose a high-resolution and wide-range temperature sensor based on chip-scale WGMRs,which utilizes a Si_(3)N_(4)ring resonator as the sensing element and a Mg F_(2)-based microcomb as a broadband frequency reference.By measuring the beatnote signal of the WGM and microcomb,the ultra-high resolution of 58 micro-Kelvin(μK)was obtained.To ensure high resolution and broad range simultaneously,we propose an ambiguity-resolving method based on the gradient of feedback voltage and combine it with a frequency-locking technique.In a proof-of-concept experiment,a wide measurement range of 45 K was demonstrated.Our soliton comb-assisted temperature measurement method offers high-resolution and wide-range capabilities,with promising advancements in various sensing applications. | CHENG ZHANG JIN WANG GUOGUO KANG JIANXIN GAO ZHIER QU SHUAI WAN CHUNHUA DONG YIJIE PAN JIFENG QU | 2023 | Photonics Research2023,11,10: | 0 |
| 19 | A cell wall invertase modulates resistance to fusarium crown rot and sharp eyespot in common wheat显示文摘Fusarium crown rot(FCR) and sharp eyespot(SE)are serious soil-borne diseases in wheat and its relatives that have been reported to cause wheat yield losses in many areas. In this study, the expression of a cell wall invertase gene, TaCWI-B1,was identified to be associated with FCR resistance through a combination of bulk segregant RNA sequencing and genome resequencing in a recombinant inbred line population. Two biparental populations were developed to further verify TaCWI-B1 association with FCR resistance.Overexpression lines and ethyl methanesulfonate(EMS) mutants revealed TaCWI-B1 positively regulating FCR resistance. Determination of cell wall thickness and components showed that the TaCWI-B1-overexpression lines exhibited considerably increased thickness and pectin and cellulose contents. Furthermore, we found that TaCWI-B1 directly interacted with an alphagalactosidase(TaGAL). EMS mutants showed that TaGAL negatively modulated FCR resistance. The expression of TaGAL is negatively correlated with TaCWI-B1 levels, thus may reduce mannan degradation in the cell wall, consequently leading to thickening of the cell wall. Additionally, TaCWI-B1-overexpression lines and TaGAL mutants showed higher resistance to SE;however, TaCWI-B1 mutants were more susceptible to SE than controls.This study provides insights into a FCR and SE resistance gene to combat soil-borne diseases in common wheat. | Guoguo Lv Yixiao Zhang Lin Ma Xiangning Yan Mingjie Yuan Jianhui Chen Yongzhen Cheng Xi Yang Qi Qiao Leilei Zhang Mohsin Niaz Xiaonan Sun Qijun Zhang Shaobin Zhong Feng Chen | 2023 | Journal of Integrative Plant Biology2023,65,7: | 0 |
