| 1 | Dependence of nitrogen concentration in type Ib diamonds on synthesis temperature显示文摘Type Ib diamonds were grown by the temperature gradient method (TGM) at 5.5 GPa and 1500-1560 K in a china-type cubic anvil high pressure apparatus using Ni70Mn25Co5 alloy as solvent/catalyst. The concentration of nitrogen (CN) in type Ib diamonds synthesized at different synthesis temperatures was measured by a Fourier transform infrared (FTIR) spectrometer. The dependence of CN in diamond on synthesis temperature was studied. For the type Ib diamonds synthesized using Ni70Mn25Co5 as catalyst, its CN decreases along with the increase of synthesis temperature. | TIAN Yu JIA XiaoPeng ZANG ChuanYi LI ShangSheng XIAO HongYu ZHANG YaFei HUANG GuoFeng LI Rui HAN QiGang MA LiQiu LI Yong CHEN XiaoZhou ZHANG Chong MA HongAn | 2009 | Chinese Science Bulletin2009，54，9： | 5 |

| 4 | Bending Resistance and Anisotropy of Basalt Fibers Laminate Composite with Bionic Helical Structure显示文摘The appendages of mantis shrimp often bear bending loads from different directions during the in the process of preying on prey with its grazing limb.Hence,it has excellent bending resistance and isotropy to confront complex and changeable external load.The outstanding performance owes to the helical Bouligand structure with a certain interlayer corner,which is also widely found in other natural materials.Hence,the bio-inspired materials with basalt fiber are fabricated with outstanding bending resistance,isotropy and toughness.The research shows laminates with 18°interlayer corners exhibit relatively excellent bending resistance and isotropy,and the laminate with 11.25°interlayer corner has best toughness.Compared with traditional composites,average bending strength along different loading direction of bio-inspired materials increased by 28%,and anisotropy decreased by 86%.Besides,the maximum toughness of laminates can increase to 1.7 times of the original.Following the introduction of interlayer corners,the bio-inspired composite tends to be isotropic.To explore the reason for the change of the isotropic performance caused by diverse interlayer corners,the Finite Element Analysis based on classical laminate theory and Tsai–Wu and Tsai–Hill failure criterion.Besides,further experiments and observations are conducted to explore possible reasons.In conclusion,following the introduction of interlayer corners,the bio-inspired composites tend to be isotropic.This bio-inspired composites are expected to be applied to various complex modern engineering fields,such as vehicle,rail transit and aerospace. | Binjie Zhang Qigang Han Hanlin Qin Junqiu Zhang Shichao Niu Zhiwu Han Luquan Ren | 2022 | Journal of Bionic Engineering2022，19，3： | 0 |
| 5 | Optimal Design and Mechanical Simulation of Rubber bushing with Convex Hull Structure Based on Bionics显示文摘Inspired by the safe landing of cats falling from high altitudes,a bionic flexible rubber bushing structure is proposed and its motion characteristics are systematically studied to explore its potential application in the suppression of vibration.The convex hull structure on the bushing surface is abstracted from the cat’s claw pad,and the hyper-viscoelastic model is selected as the constitutive model of the rubber material.In addition,the design with the best vibration damping effect is finally obtained by reasonably adjusting the amount of radial compression and distribution of bionic structures.Finally,under the same conditions,the test results of the dynamic characteristics of the bushing verify the accuracy of the simulation results.Research results show that the convex hull bionic structure designed in this paper can effectively change the motion characteristics of the rubber bushing under various working conditions,which provides new inspiration or potential possibility for the design of rubber bushing in the future. | Ce Liang Min Li Jicai Liang Shaoqiang Wang Qigang Han Yi Li | 2023 | Journal of Bionic Engineering2023，20，5： | 0 |
| 6 | Etiological characteristics of influenza-like illness in Jiangsu province from 2012 to 2016显示文摘Influenza-like illness(ILI)is an acute respiratory infection caused by various pathogens.However,the epidemiologic characteristics of ILI pathogens in Jiangsu province are unclear.To better understand the ILI etiology,the characteristics of the pathogens from nasopharyngeal swab samples of patients with ILI collected from 2012 to 2016 in 6 hospitals in Jiangsu province were studied.The pathogens,including influenza virus,respiratory syncytial virus(RSV),rhinovirus(HRV),adenovirus(ADV),herpes simplex virus(HSV),human coronavirus(hCoV),Streptococcus pneumoniae and Haemophilus influenzae,were detected by real-time PCR.At least one pathogen was identified in 1334 of the patients(40.23%).Among viruses,HRV,influenza A virus(Flu A),ADV and RSV were the most frequently detected.ADV was the only pathogen that was distributed evenly in different years and regions(P>0.05).The etiological distribution varied in different age groups.Streptococcus pneumoniae was the most common pathogen in co-infections with a co-detection rate of 64.57%(319/494).The spectrum of etiologies could help to estimate disease burden and provide guidance for vaccination. | Ke Xu Xiang Huo Rongqiang Zu Shenjiao Wang Yuanfang Qin Qigang Dai Xian Qi Huiyan Yu Lilin Chen Lei Hong Yangting Xu Qianhua Yi Weixiang Wang Xuan Wang Wenjun Dai Jie Zha Weining Han Changjun Bao | 2019 | The Journal of Biomedical Research2019，33，6： | 0 |
