| 1 | Quality prediction of freshly-harvested wheat using Gluto Peak during postharvest maturation显示文摘Much recent researches have demonstrated that the quality of freshly-harvested wheat could be improved during postharvest maturation by determinating the rheological properties.However,this process is time-consuming and complex.This study aimed to provide a rapid and convenient method for predicting wheat quality during postharvest maturation by use of Gluto Peak device.Farinograph and Extensograph were used to determine the rheological properties of four wheat samples(WT1,WT2,WT3,WT4)stored under different conditions(WT1:15℃,50%RH;WT2:20℃65%RH;WT3:28℃75%RH;WT4:35℃85%RH)for a total of 10 weeks,and Gluto Peak test was used to determine the gluten aggregation properties of the four samples.Correlation analysis was also conducted between the rheological properties and the gluten aggregation properties.Results of rheological properties showed that all Extensographic properties(dough extensibility,resistance,maximum resistance and area)of the four samples increased along with the storage time,and the Farinographic properties(water absorption,dough development time,dough stability time,and farinograph quality number(FQN))had the same tendency,indicating that the rheological properties were improved considerably with storage time extending.The Gluto Peak curves revealed that Peak Maximum Time(PMT),Brabender Equivalents Maximum(BEM)and Energy to Maximum Torque(En MT)of wheat flour of the four samples varied greatly,particularly the PMT and En MT of the samples WT3 and WT4 increased remarkably.Results of correlation analysis showed that En MT had significant correlation with water absorption and area(P<0.05)for sample WT1,and also showed significant correlation with dough development time(P<0.05)for sample WT2.For sample WT3,PMT was significantly correlated with the dough development time,extensibility,area(P<0.05),and FQN(P<0.01);and En MT was in significant correction with water absorption(P<0.01),and dough stability time,FQN,extensibility,maximum resistance and area(P<0.05).For sample WT4,both PMT and En MT had significant correction with area(P<0.05).The study indicated that the Gluto Peak test is effective in quality prediction for the freshly-harvested wheat during postharvest maturation,making it possible to realize rapid wheat quality detection and evaluation in storage period. | Mengyu Mu Ruidie Geng Yuanyuan Yue Feng Jia Xia Zhang Jinshui Wang | 2021 | Grain & Oil Science and Technology2021，4，4： | 5 |

| 3 | Microstructures and Mechanical Properties of Al-Mg-Sc-Zr Alloy Additively Manufactured by Laser Direct Energy Deposition显示文摘An Al-Mg-Sc-Zr alloy was additively manufactured by laser direct energy deposition(DED)under different laser powers,and the microstructures and mechanical properties of the as-deposited samples were investigated.The samples showed a fully equiaxed grain structure with grain sizes of 2–30μm.Most of the blocky primary Al3(Sc,Zr)-precipitated phases(<5μm)were arranged along the grain boundaries.A small amount of fine granular secondary Al3(Sc,Zr)phases(<0.5μm)were precipitated owing to the cyclic heat treatment during the DED forming process.According to the EBSD(Electron backscatter diffraction)results,the texture index and strength of the sample were only slightly greater than 1,indicating that the material structure exhibited a certain but not obvious anisotropy.The sample in the horizontal direction had better yield strength,tensile strength,and elogation properties(399.87 MPa,220.96 MPa,9.13%)than that in the building direction(385.40 MPa,219.40 MPa,8.24%),although the sample in the〈XOZ〉plane had the finest equiaxed grains.The ductility of the〈XOZ〉sample deteriorated as the number of pores increased. | Qian Hua Wenjun Wang Ruidi Li Hongbin Zhu Zehuan Lin Rong Xu Tiechui Yuan Kai Liu | 2022 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2022，1，4： | 1 |

| 6 | Microstructure and Mechanical Properties of Selective Laser Melted Al–2.51Mn–2.71Mg–0.55Sc–0.29Cu–0.31Zn Alloy Designed by Supersaturated Solid Solution显示文摘Selective laser melting(SLM)of aluminium alloys for lightweight application is arousing widespread interest,but the available alloy compositions are limited due to unsatisfactory mechanical performances.The rapid solidifi cation of SLM provides a pathway to design a novel alloy composition with extended solubility.This strategy is demonstrated by an additively manufactured novel Al–2.51 Mn–2.71 Mg–0.55 Sc–0.29 Cu–0.31 Zn alloy with the supersaturated solid solution in the present study.The microstructure of as-build sample is characterized with multi-modal grains with the fi ne equiaxed grain(FEG,~800 nm)at molten pool boundaries,coarse equiaxed grain(CEG,~2μm)and columnar dendrites(CD,~4μm)inside the molten pool,which relates to the precipitations type and distribution.It is observable that Al 3(Sc,Zr)precipitation particles with the size of~50 nm are dispersed in the FEG zone,while the interior of CEG shows no Al3(Sc,Zr)particle which only exists at the CEG boundaries.Regardless of FEG,CEG or CD,the slender Al6 Mn precipitation with the length of~500 nm is distributed along the grain boundaries.Meanwhile,a lot of vacancies and thickness fringes are detected in the FEG zone,which confi rms the supersaturated solid solution in laser rapid solidifi cation.The ultimate tensile strength and yield strength of the as-printed sample are~380 MPa and~330 MPa,respectively,with elongation~14%,which increase to~440 MPa and~410 MPa with a reduction of elongation to~9%after heat treatment. | Minbo Wang Ruidi Li Tiechui Yuan Haiou Yang Pengda Niu Chao Chen | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，3： | 1 |
| 7 | A Comparative Study on the Microstructure and Properties of ITO Targets and Thin Films Prepared from Two Different Powders显示文摘With the rapid development of indium tin oxide(ITO)in the electronic display industry,choosing which raw powders to prepare high-quality ITO targets has always been a controversial topic.In the work,in order to clearly understand the effect of the raw powders on the microstructure and properties of ITO targets and thin films,tin-doped indium oxide(dITO)and In_(2)O_3-SnO_(2)mixed(mITO)powders were chosen to prepare ITO targets for depositing the films and a comparative study on their microstructure and properties was conducted.It is found that,(1)dITO targets possess a higher solid solubility of tin in indium oxide and more uniform elemental distribution,while there are a higher density,a finer grain size and a higher mass ratio of In_(2)O_3 to SnO_(2)for the mITO targets;(2)dITO films with more coarser columnar grains and a rougher surface prefer to grow along the[100]direction in an Ar atmosphere;(3)the conductive property of ITO films only depends on the doping amount of tin and is independent of the raw powders and the preparation process of the target source;(4)dITO films possess the superior optical property and narrower optical band gap;(5)the etching property of mITO films is superior to that of dITO films due to the lower solid solubility of tin in indium oxide. | Fangsheng Mei Tiechui Yuan Ruidi Li Jingwei Huang | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，5： | 1 |

| 14 | Microstructure and mechanical properties of Al-Si-Ni coating on Cu-Cr substrate prepared by multi-permeation and friction stir processing显示文摘The surface of copper-chromium alloy was processed by Al-Si-Ni multi-permeation and friction stir processing,and the microstructure and mechanical properties of the surface layer were tested by scanning electron microscopy(SEM),energy dispersive spectroscopy(EDS),microhardness tester and friction testing machine.The results show that Al,Si and Ni elements are fully permeated into the surface of copper-chromium alloy after multielement co-infiltration and friction stir processing.In the observation of the microstructures,we found that the reticular structure is fragmented and distributed in the stir zone region.Microstructure becomes finer and grains refinement.The micro hardness of the copper-chromium alloy increased to 129 HV,44.9%higher than that of the original matrix.The main reasons of microhardness enhancement are solid solution strengthening,fine grains strengthening and dispersion strengthening.The friction test results show that the friction coefficient is basically stable at 0.69 and the wear mass is only 0.0017 g after 10 min of friction test.The improvement of wear resistance was attributed to the increase of microhardness of the alloy surface. | Yin Wang Ruidi Li Tiechui Yuan | 2019 | Nano Materials Science2019，1，3： | 1 |

| 18 | Design of a finite impulse response filter for rapid single-flux-quantum signal processors based on stochastic computing显示文摘Rapid‐Single‐Flux‐Quantum(RSFQ)circuit technology is well known for its low power consumption and latency,which enables digital signal processing up to tens of GHz.As a fundamental digital filter,the Finite Impulse Response(FIR)filter has wide applications in communication systems.A design of an FIR filter based on RSFQ circuit technology is proposed.However,the FIR filter consumes large amounts of adders and multipliers.Based on Stochastic Computing(SC)theory with which adder and multiplier are much simpler,the hardware cost of FIR filter is dramatically reduced.A novel stochastic number generator(SNG),a stochastic‐tobinary converter(SBC),and the FIR filter were designed and verified via logic simulation with a target frequency of 10 GHz.The results indicated the FIR filter performs correct operations.The proposed FIR filter consists of 2255 Josephson junctions(JJs)without wiring cells(i.e.,Josephson Transmission Lines(JTLs),Passive Transmission Lines(PTLs)),which is acceptable,making it possible to be used in RSFQ digital signal processors. | Ruidi Qiu Peiyao Qu Xiangyu Zheng Guangming Tang | 2023 | Superconductivity2023，，2： | 0 |
| 19 | Involvement of GluA1-AMPAR-mediated LTP in time-dependent decline of cognitive function in rats with temporal lobe epilepsy显示文摘Background:Cognitive impairment is one of the common comorbidities in patients with temporal lobe epilepsy(TLE),but the underlying mechanisms remain largely unknown.Previous studies have found significant decay of hippocampal long-term potentiation(LTP)in TLE rats with cognitive impairment.As the activation ofα-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors(AMPARs)is responsible for LTP formation and learning and memory,we investigated whether AMPARs are involved in the LTP inhibition and the TLE-associated cognitive impairments.Methods:TLE rat model was established by intraperitoneal injection of lithium chloride-pilocarpine on postnatal day 21(P21).Learning and memory performance,hippocampal expression of membrane GluA1-AMPARs,and hippocampal LTP were tested by behavioral tests,western blotting,and field potential recording,respectively,at 1,5 and 13 weeks after induction of status epilepticu(SE).Finally,the effects of(S)-AMPA,an agonist of AMPARs,on LTP and cognitive function were tested.Results:Results of behavioral tests revealed an time-dependent decline in the learning and memory of TLE rats when compared to the age-matched controls at week 5 and 13,rather than at week 1 after the induction of SE.Western blotting showed that the hippocampal expression of membrane GluA1 was significantly decreased in a time-dependent manner in the TLE rats when compared to the age-matched controls at weeks 5 and 13,rather than at week 1 after the induction of SE.Similarly,the hippocampal LTP was inhibited in a time-dependent manner in TLE rats at weeks 5 and 13,rather than at week 1 after the induction of SE.Moreover,intra-hippocampal injection of(S)-AMPA ameliorated the deficits in learning as well as spatial and emotional memory in a dosedependent manner,and partially reversed the inhibition of CA1 LTP in the TLE rats at week 13 after the induction of SE.Conclusions:The reduced expression of hippocampal membrane GluA1 may be involved in LTP decay in CA1 and cognition impairment in TLE rats. | Xiaoqing Luo Xiaoli Yu Jufang Liang Ruidi Sun Cheng Li Jun Jiang | 2021 | Acta Epileptologica2021，3，1： | 0 |
| 20 | Formation mechanism of inherent spatial heterogeneity of microstructure and mechanical properties of NiTi SMA prepared by laser directed energy deposition显示文摘Ni51Ti49 at.%bulk was additively manufactured by laser-directed energy deposition(DED)to reveal the microstructure evolution,phase distribution,and mechanical properties.It is found that the localized remelting,reheating,and heat accumulation during DED leads to the spatial heterogeneous distribution of columnar crystal and equiaxed crystal,a gradient distribution of Ni4Ti3 precipitates along the building direction,and preferential formation of Ni4Ti3 precipitates in the columnar zone.The austenite transformation finish temperature(Af)varies from-12.65℃(Z=33 mm)to 60.35℃(Z=10 mm),corresponding to tensile yield strength(σ0.2)changed from 120±30 MPa to 570±20 MPa,and functional properties changed from shape memory effect to superelasticity at room temperature.The sample in the Z=20.4 mm height has the best plasticity of 9.6%and the best recoverable strain of 4.2%.This work provided insights and guidelines for the spatial characterization of DEDed NiTi. | MengJie Luo Ruidi Li Dan Zheng JingTao Kang HuiTing Wu ShengHua Deng PengDa Niu | 2023 | International Journal of Extreme Manufacturing2023，5，3： | 0 |
