| 2 | Effect of solidification temperature range on the dendritic growth mode显示文摘Electromagnetic levitation technique was used to undercool bulk samples of Co-20% Cu and Co-60% Cu alloys and high undercoolings up to 303 and 110 K were achieved,respectively.The dendritic growth velocities were measured as a function of undercooling.The dendrite growth velocity of the Co-20% Cu alloy was much higher than that of the Co-60% Cu alloy.The experimental data were analyzed on the basis of the LKT/BCT dendritic growth model by taking into account non-equilibrium interface kinetics.It has been revealed that a transition from solute diffusion controlled dendritic growth to thermal diffusion controlled dendritic growth occurs at an undercooling of about 66 K for the Co-20% Cu alloy,whereas the dendrite growth in Co-60% Cu alloy proceeds in a solute diffusion controlled mode within a large solidification temperature range,and the solutal undercooling plays a dominant role.It is thus deduced that certain distinct solidification temperature ranges may be responsible for the different solidification modes for the two alloys. | CAO ChongDe WANG Fang DUAN LiBing BAI XiaoJun | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，1： | 0 |
| 3 | Limiting climatic factors in shaping the distribution pattern and niche differentiation of Prunus dielsiana in subtropical China显示文摘Subtropical forest in China has received much attention due to its complex geologic environment and bioclimatic heterogeneity.There have been very few studies addressing which climatic factors have shaped both distribution patterns and niche differentiation of species from this region.It also remains unclear whether phylogenetic niche conservatism retains in plant species from this biodiversityrich subtropical region in China.In this study,we used geographic occurrence records and bioclimatic factors of Prunus dielsiana(Rosaceae),a wild cherry species,combined with the classical ENM-based DIVA-GIS software to access contemporary distribution and richness patterns of its natural populations.The current distribution of P.dielsiana occupied a relatively wide range but exhibited an uneven pattern eastward in general,and the core distribution zone of its populations are projected to concentrate in the Wushan and Wuling Mountain ranges of western China.Hydrothermic variables,particularly the Temperature Seasonality(bio4)are screened out quantitatively to be the most influential factors that have shaped the current geographical patterns of P.dielsiana.By comparison with other sympatric families,climatic niche at regional scale showed a pattern of phylogenetic niche conservatism within cherry species of Ros aceae.The effect of habitat filtering from altitude is more significant than those of longitude and latitude.We conclude that habitat filtering dominated by limiting hydrothermic factors is the primary driving process of the diversity pattern of P.dielsiana in subtropical China. | Hong Zhu Xiangui Yi Yongfu Li Yifan Duan Xianrong Wang Libing Zhang | 2021 | Journal of Forestry Research2021，32，4： | 0 |
| 4 | Hepatoblastoma with neonatal necrotizing enterocolitis:Two case reports显示文摘We report two children with hepatoblastoma(HB)with a history of neonatal necrotizing enterocolitis(NEC).Case 1 was diagnosed with HB at 5 months of age.Liver enlargement was found during the NEC operation at 3 months of age and then was clinically diagnosed by imaging.After six chemotherapy courses,a partial hepatectomy was performed.Three months after ceasing the chemotherapy,a chest computed tomography scan suggested that distant metastasis of the tumor should be considered,and the lesion was removed.However,9 months after the operation,alpha-fetoprotein concentrations were increased,and abdominal imaging showed a recurrence of the tumor in situ,resulting in a hepatectomy.Case 2 was diagnosed with NEC shortly after birth and underwent an intestinal resection and anastomosis 1 month later.He was diagnosed with HB at 3 years of age.Hepatectomy was performed after five courses of chemotherapy.Chemotherapy was stopped after 10 courses,and alpha-fetoprotein concentrations were normal.At present,both children have survived and are in a healthy condition.Physicians should be aware of the possibility of HB and a history of NEC in children.Premature birth and low birth weight are common factors leading to the pathogenesis of HB and NEC.The association between these two diseases requires further study。 | Sidou He Xisi Wang Chao Duan Wen Zhao Chiyi Jiang Shihan Zhang Binglin Jian Wei Yang Tong Yu Libing Fu Huanmin Wang Xiaoli Ma | 2023 | Cancer Innovation2023，2，6： | 0 |
| 5 | Patterning single-layer materials by electrical breakdown using atomic force microscopy显示文摘The development of nanoelectronics and nanotechnologies has been boosted significantly by the emergence of 2D materials because of their atomic thickness and peculiar properties,and developing a universal,precise patterning technology for single-layer 2D materials is critical for assembling nanodevices.Demonstrated here is a nanomachining technique using electrical breakdown by an AFM tip to fabricate nanopores,nanostrips,and other nanostructures on demand.This can be achieved by voltage scanning or applying a constant voltage while moving the tip.By measuring the electrical current,the formation process on single-layer materials was shown quantitatively.The present results provide evidence of successful pattern fabrication on single-layer MoS2,boron nitride,and graphene,although further confirmation is still needed.The proposed method holds promise as a general nanomachining technology for the future. | Yajie Yang Jiajia Lu Yanbo Xie Libing Duan | 2024 | Nanotechnology and Precision Engineering2024，7，1： | 0 |
