| 1 | Relationship between the parent charge transfer gap and maximum transition temperature in cuprates显示文摘One of the biggest puzzles concerning the cuprate high temperature superconductors is what determines the maximum transition temperature(Tc,max), which varies from less than 30 to above 130 K in different compounds.Despite this dramatic variation, a robust trend is that within each family, the double-layer compound always has higher Tc,maxthan the single-layer counterpart. Here we use scanning tunneling microscopy to investigate the electronic structure of four cuprate parent compounds belonging to two different families. We find that within each family, the double layer compound has a much smaller charge transfer gap size(DCT), indicating a clear anticorrelation between DCTand Tc,max. These results suggest that the charge transfer gap plays a key role in the superconducting physics of cuprates, which shed important new light on the high Tc mechanism from doped Mott insulator perspective. | Wei Ruan Cheng Hu Jianfa Zhao Peng Cai Yingying Peng Cun Ye Runze Yu Xintong Li Zhenqi Hao Changqing Jin Xingjiang Zhou Zheng-Yu Weng Yayu Wang | 2016 | Science Bulletin2016，61，23： | 3 |
| 2 | Laser-assisted grinding of RB-SiC composites:Laser ablation behavior and mechanism显示文摘Laser ablation is an important process during Laser-Assisted Grinding(LAG)of hard and brittle materials.To realize controllable material removal during laser ablation of RB-SiC composites,ablation experiments under different Laser Energy Density(LAED)and LAG experiments are conducted.Evolution rules and mechanism of physical phase,ablation morphology and crack characteristics caused by laser irradiation are investigated.The forces of LAG and Conventional Grinding(CG)are compared.The results show that ablation surface changes from slight oxidation to obvious material removal with LAED increasing,and ablation depth increases gradually.The ablation products change from submicron SiO_(2)particles to nanoscale particles and floccule.High LAED promotes SiC decomposition and sublimation,which leads to the increase of C element.The SiC phase forms corrugated shape in recast layer and columnar shape in Heat Affected Zone(HAZ)at 56 J/mm^(2).The cold and heat cycle leads to formation of fishbone crack.For ablation specimen under 30 J/mm^(2),the grinding force can be reduced by a maximum of 39%and brittle damage region is reduced.The material removal and microcrack generated will significantly reduce the hardness and improve machinability,which can promote grinding efficiency. | Zhigang DONG Wenchao SUN Xintong CAI Feng YANG Yan BAO Renke KANG Dongjiang WU Guangyi MA Fangyong NIU | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |
| 3 | Role of selenoprotein M knockdown in the melatonin antagonism of nickel-induced apoptosis and endoplasmic reticulum stress in mouse heart显示文摘The aim of this study was to investigate the role of selenoprotein M(SelM)in endoplasmic reticulum stress and apoptosis in nickel-exposed mouse hearts and to explore the detoxifying effects of melatonin.At 21 d after intraperitoneal injection of nickel chloride(NiCl_(2))and/or melatonin into male wild-type(WT)and SelM knockout(KO)C57BL/6J mice,NiCl_(2)was found to induce changes in the microstructure and ultrastructure of the hearts of both WT and SelM KO mice,which were caused by oxidative stress,endoplasmic reticulum stress,and apoptosis,as evidenced by decreases in malondialdehyde(MDA)content and total antioxidant capacity(T-AOC)activity.Changes in the messenger RNA(mRNA)and protein expression of genes related to endoplasmic reticulum stress(activating transcription factor 4(ATF4),inositol-requiring protein 1(IRE1),c-Jun N-terminal kinase(JNK),and C/EBP homologous protein(CHOP))and apoptosis(B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),Caspase-3,Caspase-9,and Caspase-12)were also observed.Notably,the observed damage was worse in SelM KO mice.Furthermore,melatonin alleviated the heart injury caused by NiCl_(2)in WT mice but could not exert a good protective effect in the heart of SelM KO mice.Overall,the findings suggested that the antioxidant capacity of SelM,as well as its modulation of endoplasmic reticulum stress and apoptosis,plays important roles in nickel-induced heart injury. | Xintong ZHANG Xiaoxue GAI Lihua XU Wenxue MA Qiaohan LIU Bendong SHI Cheng FANG Jingzeng CAI Ziwei ZHANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，5： | 0 |
