| 1 | High-temperature tribological properties of Ni-P alloy coatings deposited by electro-brush plating显示文摘High-temperature tribological properties of Ni-P alloy coatings processed by electro-brush plating on 20CrMo steel have been investigated. A ball-on-disc configuration was employed and 4 mm diameter Si3N4 balls were used as static counterpart. All the wear tests were carried out at 450°C for 180 min without lubricants. The electro-brush plating Ni-P coating is amorphous in as-deposited condition, and it becomes polycrystalline with the formation of Ni and Ni3P after heat treatment at 450°C for 1 h. The friction coefficient of the Ni-P coating is just 50% of that of the 20CrMo steel at the friction temperature of 450°C. A mild adhesive wear mechanism was found for the electro-brush plating Ni-P coating tested at 450°C, whereas for the 20CrMo steel at the same temperature a mixed adhesive and abrasive wear mechanism was observed. | LI Zhiming QIAN Shiqiang WANG Wei SHEN Hongwei LONG Hesun | 2011 | Rare Metals2011，30，6： | 6 |

| 8 | The Relationship between Plant Community Structure and Their Ability to Absorb and Subtract PM_(2.5)显示文摘The research aimed to study absorption and reduction of PM_(2.5)by different plant community structure,and explore which plant community can have better or best comprehensive absorption efficiency,thereby improving and optimizing urban vegetation structure,further promoting improvement of urban air quality,improving people's quality of life,and ensuring a good living environment.In this paper,the method of quadrat survey commonly used in field survey was adopted to record the height,coverage,DBH and other indicators of statistical plants,and corresponding comprehensive value was calculated through these indexes.PM_(2.5)was measured at forest edge,4 and 8 m in the forest,with three repetitions.Subtraction amount of PM_(2.5)determined at different layers was analyzed,as well as its relationship with comprehensive value of community structure.The results showed that PM_(2.5)amount decreased significantly at forest edge,4 and 8 m in the forest,and better community structure had a positive effect on PM_(2.5)absorption.The higher the comprehensive indexes of community structure such as plant height,DBH(arbor),density and coverage,the better the ability of absorbing and reducing PM_(2.5).Therefore,it must pay attention to the diversity of plant species per unit area,to build a good plant community structure,which could better improve structure of local ecosystem,and play a good role in absorbing and reducing PM_(2.5)pollutants in the atmosphere. | Yuyuan HUANG Haiyang WEN Huina YANG Chengxi JIANG Hong LIANG Song MA Zhijie CHEN Zhiming YANG Lijuan HUANG Xinfan YU Long HE Suni DENG Wanmin ZHOU Shengyuan WU | 2021 | Meteorological and Environmental Research2021，12，3： | 1 |
| 9 | Rational design of eco-friendly Mn-doped nonstoichiometric CuInSe/ZnSe core/shell quantum dots for boosted photoelectrochemical efficiency显示文摘Colloidal core/shell quantum dots(QDs)with environment-friendly feature and controllable optoelectronic properties are promising building blocks in emerging solar technologies.In this work,we rationally design and tailor the eco-friendly CuInSe(CISe)/ZnSe core/shell QDs by Mn doping and stoichiometric optimization(i.e.,molar ratios of Cu/In).It is demonstrated that Mn doping in In-rich CISe/ZnSe core/shell QDs can effectively engineer the charge kinetics inside the QDs,enabling efficient photogenerated electrons transfer into the shell for retarded charge recombination.As a result,a solar-driven photoelectrochemical(PEC)device fabricated using the optimized Mn-doped In-rich CISe/ZnSe core/shell QDs(Cu/In ratio of 1/2)exhibits improved charge extraction and injection,showing a~3.5-fold higher photocurrent density than that of the pristine CISe/ZnSe core/shell QDs under 1 sun AM 1.5G illumination.The findings indicate that transition metal doping in“green”nonstoichiometric core/shell QDs may offer a new strategy for achieving high-efficiency solar energy conversion applications. | Rui Wang Xin Tong Zhihang Long Ali Imran Channa Hongyang Zhao Xin Li Mengke Cai Yimin You Xuping Sun Zhiming Wang | 2022 | Nano Research2022，15，8： | 1 |

| 11 | Dispersion and support dictated properties and activities of Pt/metal oxide catalysts in heterogeneous CO oxidation显示文摘The source of activity of metal/metal oxides has always been an interesting,important but highly challenging research topic in heterogeneous catalysis.In CO oxidation reaction,this work clarifies dispersion and support dictated activities of Pt including single-atom(Pt1),2.8 nm(PtNP-S)and 36 nm(PtNP-L)Pt supported on both reducible TiO_(2) and“inert”Al_(2)O_(3) supports.The X-ray absorption fine structure(XAFS)shows that chemical state of Pt is affected by both dispersion and support:Pt1 presents fully oxidized state in both Pt1/TiO_(2) and Pt1/Al_(2)O_(3);PtNP-S in PtNP-S/TiO_(2) appear nearly oxidized state while about half of Pt is metallic state in PtNP-S/Al_(2)O_(3);PtNP-L in both PtNP-L/TiO_(2) and PtNP-L/Al_(2)O_(3) exhibit metallic state.All the Pt species supported on TiO_(2) present much lower apparent activation barriers(Eapp)than that on Al_(2)O_(3).Moreover,Pt1/TiO_(2) possesses dozen times of efficiency than PtNP-S/TiO_(2) although they have similar Eapp values.A truth is finally made clear that a reducible metal oxide with low oxygen vacancy formation energy is critical to endow Pt/metal oxide a high activity and the single-atom dispersion of Pt is the way to maximize the active sites of Pt/metal oxide. | Jiaojiao Song Yixuan Yang Shoujie Liu Lei Li Nan Yu Yuteng Fan Zhiming Chen Long Kuai Baoyou Geng | 2021 | Nano Research2021，14，12： | 1 |

| 13 | YSO coded aperture camera based on depth of interaction for location correction显示文摘Purpose Coded aperture imaging was a widely used imaging method for radiation sources.However,the traditional gamma camera based on two-dimensional projection information for coded aperture imaging ignored the influence of the interaction depth of particles and detectors on the projection information,which reduced the imaging quality of the camera to some extent.Therefore,a method of correcting the coded gamma camera based on the interaction depth of particles and detectors is proposed to improve the location accuracy of detectors.Methods The camera developed in this work uses a 7×7 YSO crystal array coupled with two 7×7 Si-PM arrays.The crystal is evenly divided into 11 parts in the depth direction,with a voxel size of 3×3×3 mm3.The coded mask is a 13×13 array,which is a mosaic of two cycles of 7×7 modified uniformly redundant array mask.The depth resolution of the detector is obtained via the subsurface laser engraving dual-end readout method.After obtaining the three-dimensional position information of the interaction point the projection information obtained by the detector is layered,and the image is reconstructed.According to the spatial position information of the detector and the coded mask,the corresponding field of view of each layer of the detector is calculated,and the reconstructed image of each layer is amplified and superimposed according to the ratio of the field of view to obtain the reconstructed image combined with the depth information.Results and conclusion According to Monte Carlo simulation and radiation source imaging experiment results,this method can effectively improve the positioning ability of the detector.For the experimental scenario mentioned in the paper,the location accuracy can be improved by up to 1.54°. | Yiding Han Xiaopan Jiang Haohui Tang Xiuzuo Liang Xuanhou Hu Xianchao Huang Zhiming Zhang Lei Shuai Jing Guo Long Wei | 2023 | Radiation Detection Technology and Methods2023，7，4： | 0 |
| 14 | An efficient method and system for simultaneously measuring the performance of vast scintillating materials显示文摘A method and system for automatically and simultaneously measuring the light output of multiple scintillators,or each scintillating unit of an array,were developed.Using a large area flat panel PSPMT H8500,the light output and energy resolution were obtained automatically by comparing with reference scintillators or array using an Energy Table,Look-up Table and energy spectrum data.The aim of developing an efficient performance evaluation of scintillators was achieved.Using the method,a scintillator performance testing system was set up and six LYSO crystals and a 3×3 LYSO array were measured.The results showed that the light output and energy resolution were accurately measured automatically.The deviation of repeat measurements for the same sample was not more than 2%,and the nonlinear deviation of the system was not more than 3%.The system is suitable for measuring the performance of crystals,especially where the mass measurement of crystals and arrays is required. | CHEN Yan ZHANG Zhiming LI Daowu SHUAI Lei HUANG Xianchao TANG Haohui LI Ting ZHUANG Kai WANG yingjie LIU Yantao ZHANG Yiwen CHAI Pei LIU Shuangquan ZHU Meiling WANG Baoyi WEI Long | 2012 | Nuclear Science and Techniques2012，23，3： | 0 |
| 15 | Image reconstruction for the coded aperture system in nuclear safety and security using a Monte Carlo-based system matrix显示文摘Purpose Accurate localization of radioactive materials is critical to nuclear safety and nuclear security.A coded aperture imaging system provides a visualization solution.However,the correlation method has poor reconstruction performance for sources with low counts and for extended sources.Methods In this study,a Monte Carlo optimization-based MLEM algorithm(MC-MLEM)is proposed.The system matrix was obtained by accurate Monte Carlo simulation,so the physical effects such as mask penetration that affect the imaging process were taken into account in the MLEM algorithm.In the simulation process,the normalization of the system matrix was realized by controlling the source at different position of the source plane to have the same activity and emission angle.Results The experimental results showed that compared with the correlation method,the MC-MLEM algorithm could improve the signal-to-noise ratio and angular resolution and locate the source position quickly and accurately under low count conditions.Furthermore,the MC-MLEM algorithm could reconstruct the shape of the extended source and the expected activity ratio of cold-hot sources with large activity differences.Conclusion The MC-MLEM algorithm improved the imaging results and enhanced the reconstruction performance. | Yue Yu Xiaoli Sun Zhiming Zhang Shuangquan Liu Xiuzuo Liang Daowu Li Lei Shuai Tingting Hu Long Wei | 2023 | Radiation Detection Technology and Methods2023，7，2： | 0 |

| 17 | Experiment validation of the high stability of long-term transmitted gamma photon counting of a new CdZnTe semiconductor detector and its preliminary applications显示文摘Purpose To develop a detector system with high stability in counting the detection of transmitted gamma photons,which can be applied in the area of non-destructive testing.Method We used the cadmium zinc telluride(CZT)detector with single-polarity electrodes to substitute the traditional scintillator detector and front-end read-out electronics based on our self-designed low-noise charge-sensitive amplifier.Results and conclusion The energy resolution of 662 keV from 137Cs radioactive source was improved to 1.9%,and the relative standard deviation of different total counts of transmitted photons detected decreased to 0.05%when the counts were more than 5×107,which means the impact from the statisticalfluctuation of long-term gamma photons counting will not be a main obstacle to achieving high precision in the area of non-destructive testing.The preliminary experiment of inspecting the inner gaps in the metal rodsfilled with samples also proved to have good prospects for the CZT detector in non-destructive testing. | Chao Wang Yantao Liu Xiaopan Jiang Xianchao Huang Xiaoming Wang Yu Xiang Yiding Han Long Wei Zhiming Zhang | 2022 | Radiation Detection Technology and Methods2022，6，3： | 0 |
| 18 | Value Production,Value Transfer and Accumulation:A Political Economics Analysis of Uneven Regional Development in China显示文摘This paper aims to understand China’s uneven regional development in recent years on the basis of on political economics theories.We summarizes two theories from the political economics on uneven regional development-framework of production and framework of exchange-and unifi es them by theories of labor value and capital circulation.It means to show that uneven regional development will be explained with value production,value realization and capital accumulation,and their interactions as well.This framework can not only explain regional disparities in a static sense,but also presents dynamically developments of regional disparities-first rising and then falling.Empirical research finds China’s regional disparities result mainly from the value production gap.During the period of analysis,China went through a capital accumulation biased towards less developed regions,jointly shaped by market logic and government behavior.It made the effect of reducing regional disparities stronger than the“polarization effect”around 2007,producing a narrowing of disparities across regional development. | Zhixuan Feng Bangxi Li Zhiming Long Chen Zhang | 2022 | China Finance and Economic Review2022，11，1： | 0 |
| 19 | A preliminary study on 3D position reconstruction ofmonolithic crystal readout显示文摘Purpose Compared to pixelated crystal detectors,monolithic crystal detectors present more advantages.Without reflective layer between crystal pixel,monolithic crystal detectors provide higher detection efficiency while being cheaper.Another important feature is that monolithic crystal detectors can provide depth of interaction(DOI)information,which can improve image quality in nuclear imaging systems.In this article,we aim to study a new positioning scheme of this kind of detector in order to push its applications in nuclear imaging systems.Methods Fan-beam collimation and convolutional neural network are combined to reconstruct interaction points in crystal.Firstly,we built a monolithic detector model based on Geant4 and validated this positioning scheme with simulation data.Then,we constructed a monolithic GAGG(Ce)detector and evaluated its performance with experimental data.Results With proposed positioning scheme,in experiment,we obtained~1.7 mm FWHM resolution on average in x-/ydirection,while~2.5 mm FWHM resolution on average in DOI direction for a 33×33×10 mm3 monolithic GAGG(Ce)crystal coupled with 8×8 SiPM array.Conclusion Through simulations and experiments,we validated our positioning scheme,i.e.,fan-beam collimation and convolutional neural network.Convolutional neural network can reconstruct 3D positions of gamma-rays interaction points in a high resolution,and fan-beam collimation can provide high calibration efficiency;with combination of them,we established a high position resolution and high calibration efficiency positioning scheme for monolithic crystal detector. | Wen He Xianchao Huang Yingjie Wang Baotong Feng Meiling Zhu Shuangquan Liu Zhiming Zhang Long Wei | 2021 | Radiation Detection Technology and Methods2021，5，1： | 0 |
| 20 | Simulation research on time resolution based on Cherenkov radiation显示文摘Purpose A faster time performance can be achieved by focusing on prompt emitted photons,such as Cherenkov photons.In this study,the time fluctuations of Cherenkov photons transmission in the three Cherenkov radiators were first simulated,and we evaluated the detector performance and discussed ways to improve the coincidence time resolution(CTR)results for the detector with the three radiators.Finally,we compared detection efficiency of Cherenkov radiation in three radiators.Methods In this work,we recorded the step-by-step information of Cherenkov photons and the electrons that produced them in the radiator,information of photons on the photon outputting surface,and the step-by-step information tracing of the par-ent charged particles(electrons)to evaluate the factors influencing the performance time of the detector based on Geant4.Specially,we usually use a photon amplitude timing in the experimental implements,and the arrival time of an event is defined as the arrival time of the first photon of the event accordingly.Results The time fluctuations of Cherenkov photons transmission in the three Cherenkov radiators with a 5 mm length were simulated as 28.5 ps for PbF,40.1 ps for PbWO_(4),and 24.7 ps for Al_(2)O_(3).After considering other factors such as quantum efficiency(QE)of 30%and transit time spread(TTS)of 10 ps from the process of practical electronics,the CTR of a pair of single-pixel detectors were 56.6 ps for PbF_(2),78.8 ps for PbWO_(4),and 46.3 ps for Al_(2)O_(3) with a thickness of 5 mm.The detection efficiency of PbF_(2) is 32.25%,PbWO_(4) of 31.91%and Al_(2)O_(3) of 8.14%in the case of 5 mm length.Conclusions The simulation results indicated that using the Cherenkov photons produced in PbF_(2),PbWO_(4),Al_(2)O_(3) for detec-tor timing can obtain good CTR results.In this study,it demonstrates that it is possible to achieve a pretty good CTR with an improved QE and a reduced TTS of the photodetector. | Xiaorou Han Long Wei Xianchao Huang Haohui Tang Yingjie Wang Wen He Daowu Li Zhiming Zhang | 2021 | Radiation Detection Technology and Methods2021，5，3： | 0 |
