In the paper, uniaxial compressive and tensile deformation on nanocrystalline Ni were conducted at a confining pressure of 6 GPa and temperatures up to 900 C. The determined compressive yield strength is 0.8 GPa, identical to the tensile yield strength obtained in the same deformation experiment, indicating that the Bauschinger effect is absent in nanocrystalline Ni. The yield strength obtained at 6 GPa is also comparable to that at ambient pressure, suggesting that the dislocation-mediated mechanisms are no longer activated during plastic deformation. Based on peak intensity and peak width analyses, grain rotation and grain growth are main factors underlying the plastic deformation.

16) On Aug. 24, Prof. Wang visited the North University of China in Taiyuan, and give an invited talk entitled " High Pressure: a new window in condensed matter physics" (If you can read Chinese, please click the following link for details: http://3y.nuc.edu.cn/shownews.php?newstype=D&id=928).
15) On Aug. 5, paper "Grain Size Effects on the Compressibility and Yield Strength of Copper" was accepted for publication by Journal of Physics and Chemistry of Solids. In the paper, a pair of copper samples with different grain sizes was comparatively studied under high pressure and temperature conditions by synchrotron X-ray diffraction technique. The results reveal that grain sizes negligibly affect the compressibility of Cu, and, however, the yield strength was significantly enhanced by nanocrystals.
14) On July 5, an invited review paper intituled "From Soft to Superhard: Fifty years of experiments on cold-compressed graphite" coauthored by Yuejian and Kanani (Yale) was accepted by Journal of Superhard Materials. In the paper, the journey of 50 years' efforts accompanied with controversies on elucidating the enigma of the phase transition of graphite induced by cold compression was reviewed. It includes the foremost observation of the phase transformation of graphite by electricity measurement under high pressure at room temperature, and the following many evidences that corroborate the phase transition by using various characterization techniques, as well as the recent debates on the crystal structure of the high pressure graphite phase, and the latest experiments ending those disputes among numerous theoretical predictions and showing this high pressure phase is superhard with monoclinic structure.
13) On July 2, paper intituled "Crystal structure of graphite under room-temperature compression and decompression" was accepted by Scientific Reports, a new open access journal of Nature Publishing Group. The paper focusing on the high-pressure behaviors of graphite as well as the identification of high-pressure graphite phase was prepared by Yuejian, Joseph & Kannai (Yale University), and Boris (New Mexico State University). This paper, for the first time, provides concrete experimental evidence showing that under high-pressure graphite transits into M-carbon, a monoclinic carbon allotrope, rather than other numerous crystal structures predicted by computational methods.
