| 2 | Microstructure and Properties of W-Cu Alloys Prepared with Mechanically Activated Powder显示文摘W-15% Cu (mass fraction) alloys were sintered with mechanically activated powder in order to develop new preparing processes and improve properties of alloys. The microstructures of the activated powder and the sintered alloy were observed. Properties such as density were measured. The results show that through mechanical activation, the particle size of the powder becomes finer to sub-micron or nanometer level, some copper was soluble in tungsten, and high density W-Cu alloys can be obtained by mechanically activated powder for its action to the activation sintering. | Chengchang Jia, Xiuhu Guan, Xuekuan Su, Changheng Hou, Shimin Fan, Jun Zhao, Zizhang Xie (Material Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China) (Beijing Research Institute of Powder Metallurgy, Beiji | 2001 | Journal of University of Science and Technology Beijing2001，8，2： | 5 |

| 11 | Identification of a class of potent USP25/28 inhibitors with broad-spectrum anti-cancer activity显示文摘Dear Editor,An increasing body of evidence suggests that USP28 could be a target for cancer treatment^(1-4).To identify its inhibitors,we screened a 100-thousand synthetic compound library and found 3 lead compounds,CT1001-1003,that showed significant inhibitory activity(Supplementary Fig.1a).The optimization of these compounds led to CT1018,a much stronger inhibitor(Supplementary Fig.1b). | Jin Peng Kun Jiang Xiao Sun Lingzhi Wu Jiewei Wang Xiaomei Xi Xu Tan Tingbo Liang Changheng Tan Pumin Zhang | 2023 | Signal Transduction and Targeted Therapy2023，8，1： | 0 |
| 12 | Phase Relationship in Nd_2(Fe_(1-x)Ni_x)_(14) B and Pr_2(Co_(1-y)Ni_y)_(14)B Pseudo-ternary Compounds显示文摘The melting behavior,solid state phase transformation and structure of pseudo-ternary compounds Nd2(Fe1-xNix)14B andPr2(Co1-yNiy)14B were studied using differential thermal analysis,optical microscopy X-ray diffraction,and electron probemicro-analysis techniques.At high temperature,eutectoid decomposition R2(Ni,M)17→R(Ni,M)5+x-Ni(M) takes place in thesetwo pseudo-ternary compounds,in the composition range x=0.6~1.0 and y=0.3~1.0,respectively.When x(or y)≤0.2,bothNd2(Fe1-xNix)14B and Pr2(Co1-yNiy)14B are single phase tetragonal.The phase constitutents of these two systems at room tempera-ture are similar in the composition range 0.6≤x(or y)≤1.0. | Wu Changheng Zhuang Yuzhi Xie Jinqiang Institute of Metal Research,Academia Sinica.Shenyang | 1989 | Rare Metals1989，9，2： | 0 |
| 13 | Second phase refining induced optimization of Fe alloying in Zn:Significantly enhanced strengthening effect and corrosion uniformity显示文摘Many non-toxic alloying elements,such as Fe,Ca,and Sr,have negligible solid solubilities in Zn matrix,leading to formation of coarse second phase particles.They exhibit low strengthening effects but highly detrimental to ductility.So refining second phase is a common pursuit for Zn alloys.The present paper takes Zn-0.3Fe alloy suffered from coarse FeZn_(13) second phase particles as a touchstone to testify microstructure refining effect through solidification with an accelerated speed and multi-pass rolling.FeZn_(13) particles are refined from 24 to 2μm,and Zn grains are refined to 5μm.As a result,the strengthening effect of Fe is enhanced significantly,with yield strength and the ultimate tensile strength of the alloy increased from 132 to 218 MPa and from 159 to 264 MPa,respectively.Furthermore,corrosion non-uniformity and penetration are much alleviated.These results show that microstructure refinement,especially on coarse intermetallic second phases,has a great potential to improve mechanical and degradation properties of biodegradable Zn alloys. | Zhangzhi Shi Changheng Li Meng Li Xiangmin Li Luning Wang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，4： | 0 |
| 14 | Crystallization and Dynamic Mechanical Behavior of Coir Fiber Reinforced Poly(Butylene Succinate)Biocomposites显示文摘The crystallization behavior,crystal morphology and form,and viscoelastic behavior of poly(butylene succinate)(PBS)and coir fiber/PBS composites(CPB)were investigated by differential scanning calorimetry(DSC),polarized optical microscopy(POM),X-ray diffraction(XRD)and dynamic mechanical analysis(DMA).The results of DSC measurement show that the crystallization temperature increases with the filling of coir fibers.POM images reveal that the spherulitic size and crystallization behavior of PBS are influenced by the coir fibers in the composites.XRD curves show that the crystal form of pure PBS and CPB are remaining almost identical.In addition,the storage modulus of CPB significantly increases comparing with the pure PBS.This predicted the dimensional stability and improved load-deformation temperature.In conclusion,the addition of coir fibers has a significant effect on the thermal properties of the matrix. | Xu Yan Changheng Liu Liang Qiao Kaili Zhu Hongsheng Tan Shuhua Dong Zhitao Lin | 2022 | Journal of Renewable Materials2022，10，4： | 0 |
| 15 | Breed identification using breed‑informative SNPs and machine learning based on whole genome sequence data and SNP chip data显示文摘Background Breed identification is useful in a variety of biological contexts.Breed identification usually involves two stages,i.e.,detection of breed-informative SNPs and breed assignment.For both stages,there are several methods proposed.However,what is the optimal combination of these methods remain unclear.In this study,using the whole genome sequence data available for 13 cattle breeds from Run 8 of the 1,000 Bull Genomes Project,we compared the combinations of three methods(Delta,FST,and In)for breed-informative SNP detection and five machine learning methods(KNN,SVM,RF,NB,and ANN)for breed assignment with respect to different reference population sizes and difference numbers of most breed-informative SNPs.In addition,we evaluated the accuracy of breed identification using SNP chip data of different densities.Results We found that all combinations performed quite well with identification accuracies over 95%in all scenarios.However,there was no combination which performed the best and robust across all scenarios.We proposed to inte-grate the three breed-informative detection methods,named DFI,and integrate the three machine learning methods,KNN,SVM,and RF,named KSR.We found that the combination of these two integrated methods outperformed the other combinations with accuracies over 99%in most cases and was very robust in all scenarios.The accuracies from using SNP chip data were only slightly lower than that from using sequence data in most cases.Conclusions The current study showed that the combination of DFI and KSR was the optimal strategy.Using sequence data resulted in higher accuracies than using chip data in most cases.However,the differences were gener-ally small.In view of the cost of genotyping,using chip data is also a good option for breed identification. | Changheng Zhao Dan Wang Jun Teng Cheng Yang Xinyi Zhang Xianming Wei Qin Zhang | 2023 | Journal of Animal Science and Biotechnology2023，14，5： | 0 |
