| 1 | Synthesis of three-dimensionally ordered porous perovskite type LaMnO_3 for Al-air battery显示文摘LaMnO_3 catalysts with three-dimensionally ordered holes perovskite structure were prepared via closepacked SiO_2 template synthesized by Stober-Frink method. SEM, XRD and BET were employed to characterize the microstructure, phases and specific surface area. CV method was used to the oxygen electrode beha-vior of catalysts. Diameter of the holes was about 330 nm, corresponding to the size of SiO_2 template. Full-cell discharge tests were performed on aluminum-air battery fabricated by porous LaMnO_3.Results showed that the discharge performance of porous LaMnO_3 were 1.54 V, 1.42 V and 1.24 V respectively when the discharge currents were set at 5 mA/cm^2,10 mA/cm^2 and 20 mA/cm^2, respectively, which were higher than that of LaMnO_3 prepared by coprecipitation method(1.33 V, 1.09 V, 0.63 V, respectively). | Fuwei Xiang Xiuhua Chen Jie Yu Wenhui Ma Yuping Li Ni Yang | 2018 | Journal of Materials Science & Technology2018，34，9： | 3 |
| 2 | Performance Validation and Analysis for Multi-Method Fusion Based Image Quality Metrics in A New Image Database显示文摘Considering that there is no single full reference image quality assessment method that could give the best performance in all situations, some multi-method fusion metrics were proposed. Machine learning techniques are often involved in such multi-method fusion metrics so that its output would be more consistent with human visual perceptions. On the other hand, the robustness and generalization ability of these multi-method fusion metrics are questioned because of the scarce of images with mean opinion scores. In order to comprehensively validate whether or not the generalization ability of such multi-method fusion IQA metrics are satisfying, we construct a new image database which contains up to 60 reference images. The newly built image database is then used to test the generalization ability of different multi-method fusion IQA metrics. Cross database validation experiment indicates that in our new image database, the performances of all the multi-method fusion IQA metrics have no statistical significant different with some single-method IQA metrics such as FSIM and MAD. In the end, a thorough analysis is given to explain why the performance of multi-method fusion IQA framework drop significantly in cross database validation. | Xiaoyu Ma Xiuhua Jiang Da Pan | 2019 | China Communications2019，16，8： | 3 |
| 3 | Loss of Lkb1 impairs Treg function and stability to aggravate graft-versus-host disease after bone marrow transplantation显示文摘Accumulating evidence suggests that a reduction in the number of Foxp3^(+) regulatory T cells(Tregs)contributes to the pathogenesis of acute graft-versus-host disease(aGVHD),which is a major adverse complication that can occur after allogeneic hematopoietic stem cell transplantation(allo-HSCT).However,the precise features and mechanism underlying the defects in Tregs remain largely unknown.In this study,we demonstrated that Tregs were more dramatically decreased in bone marrow compared with those in peripheral blood from aGVHD patients and that bone marrow Treg defects were negatively associated with hematopoietic reconstitution.Tregs from aGVHD patients exhibited multiple defects,including the instability of Foxp3 expression,especially in response to IL-12,impaired suppressor function,decreased migratory capacity,and increased apoptosis.Transcriptional profiling revealed the downregulation of Lkb1,a previously identified critical regulator of murine Treg identity and metabolism,and murine Lkb1-regulated genes in Tregs from aGVHD patients.Foxp3 expression in human Tregs could be decreased and increased by the knockdown and overexpression of the Lkb1 gene,respectively.Furthermore,a loss-of-function assay in an aGVHD murine model confirmed that Lkb1 deficiency could impair Tregs and aggravate disease severity.These findings reveal that Lkb1 downregulation contributes to multiple defects in Tregs in human aGVHD and highlight the Lkb1-related pathways that could serve as therapeutic targets that may potentially be manipulated to mitigate aGVHD. | Xiuhua Su Qianqian Wang Wei Guo Xiaolei Pei Qing Niu Maolan Liu Yuanyuan Liu Song Chen Sizhou Feng Yi He Donglin Yang Rongli Zhang Qiaoling Ma Weihua Zhai Aiming Pang Jialin Wei Yong Huang Yuechen Luo Mingzhe Han Xiaoming Feng Erlie Jiang | 2020 | Cellular & Molecular Immunology2020，17，5： | 3 |
| 4 | Texture Characteristics of Thin Grain Oriented Silicon Steel Sheet Produced by Cross Shear Rolling显示文摘Commercial grain oriented silicon steel was cold rolled to thickness from 0.06 to 0.10 mm by cross shear rolling, then annealed in vacuum or a hydrogen atmosphere furnace. Deformation textures of the sheets were researched by ODF method and reverse pole figure quantitative analyses. The results indicate that: in the condition of the cross shear rolling, the deformation texture of rolled sheet is generally similar to that of conventional rolled sheet, however, the texture distribution through the thickness is asymmetrical. With mismatch speed ratio increasing, the amount of Goss texture increases. With reduction ratio increasing, the intensity of γ-fiber becomes strong. | Xiuhua GAO, Kemin QI, Renlong LI, Chunlin QIU, Bo MA and Guangrun BAI (Department of Metal Forming, Northeastern University, Shenyang 110006, China) | 2000 | Journal of Materials Science & Technology2000，16，2： | 2 |
| 5 | Enhanced efficiency of graphene-silicon Schottky junction solar cell through inverted pyramid arrays texturation显示文摘Nanostructures of silicon are gradually becoming hot candidate due to outstanding capability for trapping light and improving conversion efficiency of solar cell. In this paper, silicon nanowires(SiNWs) and silicon inverted pyramid arrays(SiIPs) were introduced on surface of Gr-Si solar cell through silver and copper-catalyzed chemical etching, respectively. The effects of SiNWs and SiIPs on carrier lifetime, optical properties and efficiency of Gr-SiNWs and Gr-SiIPs solar cells were systematically analyzed. The results show that the inverted pyramid arrays have more excellent ability for balancing antireflectance loss and surface area enlargement. The power conversion efficiency(PCE) and carrier lifetime of Gr-SiIPs devices respectively increase by 62% and 34% by comparing with that of Gr-SiNWs solar cells. Finally, the Gr-SiIPs cell with PCE of 5.63% was successfully achieved through nitric acid doping. This work proposes a new strategy to introduce the inverted pyramid arrays for improving the performance of Gr-Si solar cells. | Jiajia Qiu Yudong Shang Xiuhua Chen Shaoyuan Li Wenhui Ma Xiaohan Wan Jia Yang Yun Lei Zhengjie Chen | 2018 | Journal of Materials Science & Technology2018，34，11： | 2 |

| 9 | Study on the key technology of spectral reflectivity reconstruction based on sparse prior by a single-pixel detector显示文摘By studying the traditional spectral reflectance reconstruction method, spectral reflectance and the relative spectral power distribution of a lighting source are sparsely decomposed, and the orthogonal property of the principal component orthogonal basis is used to eliminate basis; then spectral reflectance data are obtained by solving a sparse coefficient. After theoretical analysis, the spectral reflectance reconstruction based on sparse prior knowledge of the principal component orthogonal basis by a single-pixel detector is carried out by software simulation and experiment. It can reduce the complexity and cost of the system, and has certain significance for the improvement of multispectral image acquisition technology. | Leihong Zhang Dong Liang Bei Li Yi Kang Zilan Pan Dawei Zhang Xiuhua Ma | 2016 | Photonics Research2016，4，3： | 1 |

| 12 | Graphene Quantum Dots Open Up New Prospects for Interfacial Modifying in Graphene/Silicon Schottky Barrier Solar Cell显示文摘Graphene/silicon(Gr/Si)Schottky barrier solar cells(SBSCs)are attractive for harvesting solar energy and have been gaining grounds for its low-cost solution-processing.The interfacial barrier between graphene and silicon facilitates the reducing excessive carrier recombination while accelerating the separation processes of photo-generated carriers at the interface,which empowers the performance of Gr/Si SBSCs.However,the difficulty to control the interface thickness prevents its application.Here,we introduce the graphene oxide quantum dots(GOQDs)as a unique interfacial modulation species with tunable thickness by controlling the GOQDs particle size.The power conversion efficiency(PCE)of 13.67%for Gr/Si-based SBSC with outstanding stability in the air is obtained with the optimal barrier thickness(26 nm)and particle size(4.15 nm)of GOQDs.The GOQDs in Gr/Si-based SBSCs provide the extra band bending which further enhances the PCE for its photovoltaic applications. | Chao Geng Xiuhua Chen Shaoyuan Li Zhao Ding Wenhui Ma Jiajia Qiu Qidi Wang Chang Yan Hua-jun Fan | 2021 | Energy Material Advances2021，，1： | 0 |
| 13 | Improving open-circuit voltage and short-circuit current of high-efficiency silicon-based planar heterojunction solar cells by combining V_(2)O_(5)with PEDOT:PSS显示文摘In recent years,a novel PEDOT:PSS/n-Si planar heterojunction solar cell has been extensively studied in the photovoltaic field.Different V_(2)O_(5)-IPA concentrations mixed in PEDOT:PSS samples as hole transport layer were prepared by means of spin coating technique and mechanical mixing of organic and inorganic materials.V_(2)O_(5)was studied for its effects on the surface morphology,chemical composition,and optical transmittance of PEDOT:PSS films.The findings of the study show that the addition of V_(2)O_(5)particles changes the surface morphology of PEDOT:PSS films and promotes its superior ohmic contact with the Si interface.Furthermore,PEDOT:PSS incorporated with V_(2)O_(5)particles that have outstanding optical and semiconductor properties reduces the rate of carrier recombination at the device interface and blocks electron transport to the anode in the fabricated Si-based solar cells.When compared to conventional PEDOT:PSS/Si planar heterojunction solar cells,the fill factor,photoelectric conversion efficiency,open-circuit voltage,and short-circuit current density of the devices prepared in this study can be significantly improved,reaching up to 70.98%,15.17%,652 mV and 32.8 mA/cm^(2),respectively.This research provides a promising and effective method for improving the photoelectric conversion performance of PEDOT:PSS/Si heterojunction solar cells,which enables the application of V_(2)O_(5)in Si solar cells. | Zhiting Luo Chen Yang Xiuhua Chen Wenhui Ma Shaoyuan Li Kaixin Fu | 2023 | Journal of Materiomics2023，9，3： | 0 |
| 14 | Enhanced aging and thermal shock performance of Mn_(1.95-x)Co_(0.21)Ni_(0.84)Sr_(x)O_(4) NTC ceramics显示文摘The Mn_(1.95-x)Co_(0.21)Ni_(0.84)Sr_(x)O_(4)(MCNS)(0≤x≤0.15)based negative temperature coefficient(NTC)materials are prepared by co-precipitation method.The replacement of Mn by Sr plays a critical role in controlling the lattice parameter,relative density,microstructure,and electrical properties.The lattice parameter and relative density increase with the increase of Sr content.A small amount of Sr restrains the grain growth and increases the bulk density.Moreover,the room resistivityρ25,material constant B25/50,activation energy Ea,and temperature coefficientαvalues of MCNS ceramics are influenced by the Sr content and ranged in 1535.0–2053.6Ω·cm,3654–3709 K,0.3149–0.3197 eV,and(–4.173%)–(–4.111%),respectively.The X-ray photoelectron spectroscopy(XPS)results explain the transformation of MCNS ceramics from n-to p-type semiconductors.The conduction could arise from the hopping polaron between Mn3+/Mn4+and Co^(2+)/Co^(3+) in the octahedral sites.The impedance data analysis also discusses the conduction mechanism of the MCNS ceramic,whereas grain resistance dominates the whole resistance of the samples.Furthermore,the aging coefficient(△R/R)of MCNS ceramics is found to be<0.2%,which indicates the stable distribution of cations in the spinel.Finally,the MCNS ceramics demonstrate excellent thermal durability with<1.3%of resistance shift after 100 thermal shock cycles. | Haibing Li Huimin Zhang Slapley Thayil Aimin Chang Xu Sang Xiuhua Ma | 2021 | Journal of Advanced Ceramics2021，10，2： | 0 |
| 15 | Genetic diversity and population genetic structure of Python bivittatus in China显示文摘The Burmese python(Python bivittatus) has recently suffered large population declines in the wild in China due to illegal capture, overexploitation, deforestation and the loss of its natural habitat. Greater knowledge of the genetic diversity and structure of wild P. bivittatus populations is needed to help ensure its effective management.In this study, we investigated the genetic diversity and population genetic structure of wild P. bivittatus in China in detail. 109 P. bivittatus individuals from five distribution areas in Guangdong(GD), Guangxi(GX), Hainan(HN),Fujian(FJ) and Yunnan(YN) province of China were collected, and their genetic structure and diversity were analyzed. Eight highly polymorphic microsatellite loci were utilized to reveal high levels of genetic diversity in the P. bivittatus population. Genetic diversity was highest in GX, and lowest in GD. All geographic populations demonstrated a bottleneck effect indicating recent population decline. Fstand AMOVA analyses revealed that there was moderate genetic differentiation among the five populations, and that only 10.59 % of total genetic diversity occurred among populations. Fstvalues between populations were positively correlated with their geographical distances. Genetic structure analyses revealed that the HN,GX and GD populations, which were geographically closest, were assigned to a genetic cluster, while the YN and FJ populations constituted a single cluster,respectively. | Yubao Duan Yingshu Wang Suying Bai Xiuhua Tian Ke Rong Jianzhang Ma | 2017 | Journal of Forestry Research2017，28，3： | 0 |
