| 1 | Revealing the atomic mechanism of diamond–iron interfacial reaction显示文摘Diamond,with ultrahigh hardness,high wear resistance,high thermal conductivity,and so forth,has attracted worldwide attention.However,researchers found emergent reactions at the interfaces between diamond and ferrous materials,which significantly affects the performance of diamond-based devices.Herein,combing experiments and theoretical calculations,taking diamond–iron(Fe)interface as a prototype,the counter-diffusion mechanism of Fe/carbon atoms has been established.Surprisingly,it is identified that Fe and diamond first form a coherent interface,and then Fe atoms diffuse into diamond and prefer the carbon vacancies sites.Meanwhile,the relaxed carbon atoms diffuse into the Fe lattice,forming Fe_(3)C.Moreover,graphite is observed at the Fe_(3)C surface when Fe_(3)C is over-saturated by carbon atoms.The present findings are expected to offer new insights into the atomic mechanism for diamondferrous material's interfacial reactions,benefiting diamond-based device applications. | Yalun Ku Kun Xu Longbin Yan Kuikui Zhang Dongsheng Song Xing Li Shunfang Li Shaobo Cheng Chongxin Shan | 2024 | Carbon Energy2024，6，3： | 0 |
| 2 | Genetic Diversity and Correlation Analysis of Main Botanical Traits of Chili Pepper Genetic Resources显示文摘A total of 398 chili pepper germplasms were used as test materials and genetic diversity and correlation analysis were performed on 17 botanical traits.The results of diversity analysis showed that the diversity indexes of the 17 botanical traits ranged from 0. 15 to 5. 97 with the average value of 4. 12. The data distributions of 11 quantitative traits were more dispersed than qualitative traits. The average value of coefficient of variation was 36. 90% and the variation ranges were one to six times larger than the average value. The results of correlation analysis showed that plant height had significantly positive correlations with plant breadth,leaf length,leaf width,petiole length,the first flower node and carpopodium length. The first flower node was significantly negatively correlated with fruit length,fruit width,flesh thickness and weight per fruit and significantly positively correlated with plant height and plant breadth. The flesh thickness was significantly positively correlated with leaf length,leaf width,petiole length,fruit length,fruit width and carpopodium length. The weight per fruit was significantly positively correlated with leaf length,leaf width,petiole length,fruit length,fruit width,carpopodium length and flesh thickness. Materials with low first flower node,moderate plant height and width and large fruit should be selected for the breeding of early-maturing and high-yield chili pepper varieties. The genetic distances between chili pepper traits were calculated based on the genotypic values of the 11 quantitative traits. The genetic distances between different traits ranged from 14. 26 to 32. 99.The 11 quantitative traits were divided into seven groups when the rescaled distance was ten,which further clarified the relationships between different traits. The research results laid a solid foundation for the new variety breeding of chili pepper. | Ziji LIU Longbin SHEN Yan YANG Zhenmu CAO | 2015 | Agricultural Biotechnology2015，4，4： | 0 |
