| 1 | Dietary supplementation with Clostridium butyricum improves growth performance of broilers by regulating intestinal microbiota and mucosal epithelial cells显示文摘Clostridium butyricum has been widely considered an antibiotic substitute in recent years.It can promote growth performance,improve the immune response and enhance the intestinal barrier function of the host.In the present study,1-d-old Arbor Acres(AA)broilers were fed C.butyricum(1×109 cfu/kg)for 28 d.The transcriptomic characteristics of epithelial cells of the cecal mucosa were determined by RNA-sequence,and the cecal microbiota composition was explored by 16 S ribosomal RNA gene sequencing.The changes in the intestinal mucosa of broilers were then analyzed by tissue staining.Gene Ontology(GO)annotations identified substance transport and processes and pathways that might participate in intestinal development and cell viability.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis revealed that the differentially expressed genes are involved in numerous pathways related to amino acid and vitamin metabolism and antioxidant and defensive functions,among others.The relative expression of some genes associated with intestinal barrier function(claudins 2,15,19,and 23,tight junction proteins 1,2,and 3 and mucin 1)was significantly increased in the treatment group(P<0.05 or P<0.01).Moreover,the proportion of Firmicutes was higher in the C.butyricum-treated group,whereas the proportion of Proteobacteria was higher in the control group.At the genus level,the relative abundances of Butyricicoccus and Lactobacillus,among other bacteria,were increased after C.butyricum supplementation.The tissue staining analysis showed that the cecal mucosa of broilers was significantly ameliorated after the addition of C.butyricum(P<0.05 or P<0.01).These results showed that dietary supplementation with C.butyricum can enhance the antioxidant capacity,mucosal barrier function,and stabilize the cecal microbiota,resulting in improving the growth performance. | Laipeng Xu Xiangli Sun Xianhua Wan Keke Li Fuchun Jian Wenting Li Ruirui Jiang Ruili Han Hong Li Xiangtao Kang Yanbin Wang | 2021 | Animal Nutrition2021，，4： | 12 |
| 2 | High-Sensitivity Temperature Sensor Based on Polarization Maintaining Fiber Sagnac Loop显示文摘A high-sensitivity all-fiber temperature sensor based on a Sagnac interferometer is demonstrated by splicing a section of polarization maintaining fiber(PMF)between two sections of standard single mode fibers(SMFs).In this sensor,the SMF-PMF-SMF structure in the Sagnac loop is bent into a circle to enhance the sensitivity.The length and curvature of the PMF in the loop are investigated and can be optimized to further increase the temperature sensitivity of the sensor. Results show that the radius of the circle has an important effect upon temperature sensitivity due to the bend-induced birefringence variation of the PMF.The SMF-PMF-SMF structure bent into a circle with a radius of 30mm exhibits a high-sensitivity temperature of 1.73nm/℃.The sensor is provided with the advantages of easy fabrication,low-insertion loss,and high sensitivity,which may find potential applications in the field of high precision temperature measurement. | Laipeng SHAO Junhui HU Hanglin LU Jing DU Tianyin WU Yiping WANG | 2019 | Photonic Sensors2019，9，1： | 10 |
| 3 | Progress of graphene growth on copper by chemical vapor deposition:Growth behavior and controlled synthesis显示文摘Recently,chemical vapor deposition (CVD) on copper has been becoming a main method for preparing large-area and highquality monolayer graphene.In this paper,we first briefly introduce the preliminary understanding of the microstructure and growth behavior of graphene on copper,and then focus on the recent progress on the quality improvement,number of layers control and transfer-free growth of graphene.In the end,we attempt to analyze the possible development of CVD growth of graphene in future,including the controlled growth of large-size single-crystal graphene and bilayer graphene with different stacking orders. | MA LaiPeng REN WenCai DONG ZaiLi LIU LianQing CHENG HuiMing | 2012 | Chinese Science Bulletin2012，57，23： | 6 |

| 17 | Self-energy dynamics and the mode-specific phonon threshold effect in Kekulé-ordered graphene显示文摘Electron-phonon interaction and related self-energy are fundamental to both the equilibrium properties and non-equilibrium relaxation dynamics of solids.Although ele ctron-phonon interaction has been suggested by various time-resolved measurements to be important for the relaxation dynamics of graphene,the lack of energy-and momentum-resolved self-energy dynamics prohibits direct identification of the role of specific phonon modes in the relaxation dynamics.Here,by performing time-and angle-resolved photoemission spectroscopy measurements on Kekulé-ordered graphene with folded Dirac cones at theΓpoint,we have succeeded in resolving the self-energy effect induced by the coupling of electrons to two phonons atΩ;=177 meV andΩ;=54 meV,and revealing its dynamical change in the time domain.Moreover,these strongly coupled phonons define energy thresholds,which separate the hierarchical relaxation dynamics from ultrafast,fast to slow,thereby providing direct experimental evidence for the dominant role of mode-specific phonons in the relaxation dynamics. | Hongyun Zhang Changhua Bao Michael Schüler Shaohua Zhou Qian Li Laipeng Luo Wei Yao Zhong Wang Thomas P.Devereaux Shuyun Zhou | 2022 | National Science Review2022，9，5： | 0 |
