| 1 | Microstructural Evolution of 6061 Alloy during Isothermal Heat Treatment显示文摘The semi-solid billet of 6061 aluminum alloy was prepared by the near-liquidus semi-continuous casting(LSC) with rosette or near-spheroide grains.The pre-deformation processing was applied before partial remelting to further improve the microstructure and properties of the semi-solid alloy.The effects of different processing parameters,such as holding temperature and holding time,on the semisolid microstructures during partial remelting have been investigated.It was found that the optimal partial remelting parameters should be 630℃ and 10-15 min for 6061 alloy cold rolled with 60% reduction in height of pre-deformation.The coarsening rates were anasysed by Lifshitz-Slyozov-Wagner(LSW) theory.The pre-deformed 6061 alloy exhibits lower coarsening rate constants than that of the as-cast one,and also lower than other alloys processed by different method found in previous literature.It is because the coarsening rate is associated with the initial microstructure and composition of the alloy.The secondary phases in the alloy inhibit the migration of the liquid film grain boundaries.The microstructure obtained by using the combination of near-liquidus semicontinuous casting and pre-deformation treatment is better than that without pre-deformation processing,which demonstrates that the used method is promising for fabricating high quality semi-solid alloys. | Na Wang Zhimin Zhou Guimin Lu | 2011 | Journal of Materials Science & Technology2011，27，1： | 11 |
| 2 | Effects of operational and structural parameters on cell voltage of industrial magnesium electrolysis cells显示文摘电场是电解过程的精力基础和在一个镁电解房间的 multiphysical 地的来源。在这研究,一个三维的数字模型被开发并且过去常通过有限元素分析以稳定的状态计算电场。基于电场的模拟,运作、结构的参数例如当前的紧张,阳极厚度,阴极厚度,和阳极阴极距离(ACD ) ,被调查获得最小的房间电压。优化是获得在镁电解过程在精力消费上有重要效果的最小的电阻电压。结果显示电压上的当前的紧张的效果能被忽略, ACD 的效果是明显的。而且,在电压和阳极和阴极的厚度之间有线性减少;并且 anodecathode 工作高度也在电压上有重要效果。 | Ze Sun Chenglin Liu Guimin Lu Xingfu Song Jianguo Yu | 2015 | Frontiers of Chemical Science and Engineering2015，9，4： | 5 |
| 3 | Semi-solid extrusion of aluminum alloy ZL116显示文摘The semi-solid forward-extruding feasibility of reheated ZL116 alloy cast by the near-liquidus semi-continuous casting process was studied by analyzing the microstructures and properties of forward-extruded bars. The results show that the microstructure of the ZL116 alloy billets cast by near-liquidus semi-continuous casting is mainly made up of homogeneous, fine global-or rosette-shaped grains. The microstructure of the billets, reheated and held at 575℃, contains stable and net-spherical grains which are suitable for semi-solid thixoforming. The semi-solid forward-extruded bars of the ZL116 alloy billet are facially smooth, microstructurally fine and homogeneous. Therefore the feasibility of semi-solid forward-extrusion of ZL116 alloy is thus excellent. | Zhao Dazhi Lu Guimin Cui Jianzhong | 2008 | China Foundry2008，5，2： | 5 |
| 4 | Microstructures of an AlSi_7Mg alloy by near-liquidus casting显示文摘Semi-solid ingots of an AlSi7Mg alloy were obtained using the method of near liquidus casting. Their micro- structures exhibit the characteristics of fine, equiaxed, and non-dendrite, which are required for semi-solid forming. The in- fluences of casting temperature, heat preservation time, and cooling rate on the microstructure were also investigated. The results show that in the temperature region near liquidus the grain size becomes small with a decrease in casting temperature. Prolonging the heat preservation time makes grain crassitude at the same temperature. And increasing the cooling rate makes grain fine. The microstructure of the alloy cast with iron mould is finer than that with graphite mould. | GAO Ming WANG Ping LU Guimin CUI Jianzhong | 2007 | Rare Metals2007，26，3： | 5 |
| 5 | Influence of NO2^- on the Microscopic Structure and Physical Properties of the Binary Nitrate Salts: a Molecular Dynamics Simulation Study显示文摘Molecular dynamics simulation method was used to study the influence of NO2^- on both the structure and properties of the binary nitrate salts(60 wt.% NaNO3 + 40 wt.% KNO3). The density and viscosity of the mixtures were experimentally measured and the simulation results met well with the experimental ones. The simulation results showed that, with the addition of NO2^-, the ionic clusters tended to loose and the mobilities of all the ions tended to increase. The density, viscosity, and heat capacity decreased while the thermal conductivity increased with the increase of NO2^- concentration. The correlation between the microscopic structure and physical properties of the mixtures were discussed and revealed. | NI Haiou WU Jie SUN Ze LU Guimin YU Jianguo | 2020 | Journal of Thermal Science2020，29，2： | 2 |
| 6 | Theoretical prediction on the local structure and transport properties of molten alkali chlorides by deep potentials显示文摘In this work,the local structure and transport properties of three typical alkali chlorides(LiCl,NaCl,and KCl)were investigated by our newly trained deep potentials(DPs).We extracted datasets from ab initio molecular dynamics(AIMD)calculations and used these to train and validate the DPs.Large-scale and long-time molecular dynamics simulations were performed over a wider range of temperatures than AIMD to confirm the reliability and generality of the DPs.We demonstrated that the generated DPs can serve as a powerful tool for simulating alkali chlorides;the DPs also provide results with accuracy that is comparable to that of AIMD and efficiency that is similar to that of empirical potentials.The partial radial distribution functions and angle distribution functions predicted using the DPs are in close agreement with those derived from AIMD.The estimated densities,self-diffusion coefficients,shear viscosities,and electrical conductivities also matched well with the AIMD and experimental data.This work provides confidence that DPs can be used to explore other systems,including mixtures of chlorides or entirely different salts. | Wenshuo Liang Guimin Lu Jianguo Yu | 2021 | Journal of Materials Science & Technology2021，，16： | 2 |

| 14 | Recycle-Friendly Aluminum Alloy Sheets for Automotive Applications Based on Hemming显示文摘Unavoidably,Fe impurities are mixed into Al alloys during recycling of aluminum automotive parts.High Fe content recyclefriendly aluminum alloy sheets(RASs)are discussed in terms of their applications to car body parts and closures.RASs have advantages,such as they are low cost and light weight,they require less energy to process,and they reduce emissions when used in vehicles.The hemming ability of RASs was investigated through various quenching rates and hot-rolling reduction rates.The hemming factor(HF)values of low Fe content samples(0.1 and 0.3 wt%Fe content)were 2 and 3.The hemming ability of samples with an Fe content of 0.5 wt%was unacceptable for applications to automotive outer closures(i.e.,HF values of 4 and 5).The HF values changed from 3 to 5 for even higher Fe content samples(0.8 wt%Fe),depending on the quenching and hot-rolling reduction rates.Lower quenching(air quenching)and lower hot-rolling reduction rates(6-pass hot rolling)both improved the hemming ability of the high Fe content samples.A low-cost and recycle-friendly aluminum alloy automotive sheet from end-of-life vehicles is presented,and its hemming properties are characterized. | Hongzhou Lu Junping Zhang Ni Tian Xinli Song Mingtu Ma Guimin Lu | 2018 | Automotive Innovation2018，1，1： | 1 |
| 15 | Rationalizing the isolation distance needed for field trials involving genetically modified rapeseed (Brassica napus L.) in China显示文摘The isolation distance required for field trials of genetically modified (GM) rapeseed varies widely worldwide, with a 50-400 m distance in most nations contrasting with a minimum 1000-m isolation distance in China. The goal of this study was to evaluate the relevance of current regulations in China regarding the isolation distance needed for GM rapeseed trials. A pollen flow experiment was conducted based on the design of concentric circles, with the GM plants in a 20-m diameter circle at the centre, surrounded by non-GM plants to a distance 60 m from the perimeter of the circle containing GM plants. The rate of pollen flow was the highest at the isolation distance of 0.5 m, where it ranged from 2.3091% to 2.6711%. The general pattern of the pollen flow rate (y) with distance (x) was well described by the equation y = 1.3936x-0.9136 (R 2 = 0.9950). The long-distance pollen flow tested at the isolation distance of 800 m was 0.0018%, which agrees with the theoretical prediction. The results suggested that 300 m, rather than 1000 m, is a reasonable distance to ensure a tolerable threshold of pollen flow (less than 0.01%) under conditions of winter rapeseed production in China. | ZHAO XiangXiang TANG Tang CHEN GuiMin LIU FuXia WANG XingLong BU CuiPing LU ChangMing | 2013 | Chinese Science Bulletin2013，58，13： | 1 |

| 19 | Engineering human seleno-glutaredoxin containing consecutive rarecodons as an artificial glutathione peroxidase显示文摘The active center of human glutaredoxin(hGrx1)shares a common thioredoxin fold and specific affinity for substrate glutathione (GSH)with natural glutathione peroxidase(GPx).hGrx1 was redesigned to introduce the catalytic selenocysteine residue to imi- tate the function of antioxidant selenoenzyme GPx in vivo.The human hGrx1 scaffold is a good candidate for potential medical application compared with other animal-originated protein scaffolds.Two consecutive rare codons(AGG-AGG)in the open reading frame of hGrx1 mRNA encoding Arg26-Arg27 residues can reduce seleno-hGrx1 expression level significantly in the Cys auxotrophic Escherichia coli strain BL21cysE51.Therefore,we optimized the rare codons,which resulted in a remarkable in- crease of the expression level in the Cys auxotrophic cells,which may be sufficient for future medical production.The engineered artificial selenoenzyme displays high GPx catalytic activity,rivaling that of some natural GPx proteins.Kinetic analysis of the engineered seleno-hGrx1 showed a typical ping-pong kinetic mechanism;its catalytic properties are similar to those of some nat- urally occurring GPx proteins. | ZHANG Wei LUO Quan WANG XiaoPing ZHANG DongMei MIAO Lu XU JiaYun LUO GuiMin SHEN JiaCong LIU JunQiu | 2012 | Chinese Science Bulletin2012，57，1： | 0 |
| 20 | Novel strategy for disease risk prediction incorporating predicted gene expression and DNA methylation data:a multi-phased study of prostate cancer显示文摘Background:DNA methylation and gene expression are known to play important roles in the etiology of human diseases such as prostate cancer(PCa).However,it has not yet been possible to incorporate information of DNA methylation and gene expression into polygenic risk scores(PRSs).Here,we aimed to develop and validate an improved PRS for PCa risk by incorporating genetically predicted gene expression and DNA methylation,and other genomic information using an integrative method.Methods:Using data from the PRACTICAL consortium,we derived multiple sets of genetic scores,including those based on available single-nucleotide polymorphisms through widely used methods of pruning and thresholding,LDpred,LDpred-funt,AnnoPred,and EBPRS,as well as PRS constructed using the genetically predicted gene expression and DNA methylation through a revised pruning and thresholding strategy.In the tuning step,using the UK Biobank data(1458 prevalent cases and 1467 controls),we selected PRSs with the best performance.Using an independent set of data from the UK Biobank,we developed an integrative PRS combining information from individual scores.Furthermore,in the testing step,we tested the performance of the integrative PRS in another independent set of UK Biobank data of incident cases and controls.Results:Our constructed PRS had improved performance(C statistics:76.1%)over PRSs constructed by individual benchmark methods(from 69.6%to 74.7%).Furthermore,our new PRS had much higher risk assessment power than family history.The overall net reclassification improvement was 69.0%by adding PRS to the baseline model compared with 12.5%by adding family history.Conclusions:We developed and validated a new PRS which may improve the utility in predicting the risk of developing PCa.Our innovative method can also be applied to other human diseases to improve risk prediction across multiple outcomes. | Chong Wu Jingjing Zhu Austin King Xiaoran Tong Qing Lu Jong Y.Park Liang Wang Guimin Gao Hong-Wen Deng Yaohua Yang Karen E.Knudsen Timothy R.Rebbeck Jirong Long Wei Zheng Wei Pan David V.Conti Christopher A Haiman Lang Wu | 2021 | Cancer Communications2021，41，12： | 0 |
