| 1 | Effects of aspect ratio on shock-cylinder interaction显示文摘Interaction of a planar shock wave with a discontinuous SF& elliptic gas cylinder surrounded by air is investigated. Special attention is given to the effects of aspect ratio on wave pattern, interface evolution, and material mixing. An ideal discontinuous two-dimensional gas cylinder is created by the soap film technique in experiments, and the shocked flow is captured by schlieren photography combined with a high-speed video camera. The surface of the gas cylinder is clear enough to observe the shock motions, and the distinct interface boundaries allow us to extract more details. As aspect ratio varies, the shock focusing process is quite different. For the prolate gas cylinder, an inward jet is produced although an internal shock focusing firstly occurs. The inward jet has never been observed in membraneless prolate ellipse experiments probably because the inward jet is so faint due to less vorticity generation on membraneless interface that it is difficult to be observed. For the oblate gas cylinder, a secondary vortex pair, which has not been described clearly in previous work, is derived from the downstream interface. The material lines at early stages are extracted from experiments, which grow faster as aspect ratio increases. The in terfacial area, the mean volume fraction and the mixing rate are presented from computations, and the results show that the increase of aspect ratio promotes the mixing between gases. | Junfeng Ou Zhigang Zhai | 2019 | Acta Mechanica Sinica2019，35，1： | 4 |

| 7 | A mediator-free self-powered glucose biosensor based on a hybrid glucose/MnO_(2) enzymatic biofuel cell显示文摘Self-powered glucose biosensor(SPGB)is of great interest due to the advantages including single configuration,good stability and particularly no need of external power sources.Herein,a mediator-free SPGB with high sensitivity and good selectivity is constructed based on a hybrid enzymatic biofuel cell(EBFC)composed of a glucose oxidase/cobalt phthalocyanine/1-pyrenebutyric acid/buckypaper(GOD/CoPc/PBA/BP)bioanode and a MnO_(2)/PBA/BP capacitive cathode.The efficient electron transfer from GOD to electrodes is achieved successfully through the anode oxidation of hydrogen peroxide(H_(2)O_(2)),one nature product of glucose oxidation catalyzed by GOD,thus avoiding the potential drawbacks posed by the use of redox mediators.CoPc servers as an efficient catalyst to lower the anode potential required by the reaction of H_(2)O_(2) to 0.17 V.The MnO_(2)/PBA/BP capacitive cathode is utilized because it can not only provide a high discharge potential and adequate capacitance to match the bioanode well,but also exhibit no potential interference to the anodic reaction.The concentration of glucose can be detected simply by measuring the output of the SPGB and a wide linear detection range from 0.5 to 8 mM has been obtained with high sensitivities of 48.66 and 32.12μA·cm^(−2)·mM^(−1) with and without stirring,respectively.The recoveries of glucose in grape juice and human serum are in the range from 99.5%to 101.2%with the relative standard deviation(RSD)less than 8%,indicating the good promise of the SPGB in sensing glucose in real samples. | Shuai Hao He Zhang Xiaoxuan Sun Junfeng Zhai Shaojun Dong | 2021 | Nano Research2021，14，3： | 0 |
| 8 | Anti-fatigue Effect of L-arginine Complex Preparation on Mice显示文摘Objective:To investigate the anti-fatigue effect of L-arginine complex preparation on mice.Methods:The experimental mice were divided into a blank group,low dose group,medium dose group and high dose group.L-arginine complex preparation mice were intragastrically administered for 30 days,and the mice were tested for exhaustive swimming time.At the same time,contents of plasma lactic acid,lactate dehydrogenase,urea nitrogen and hepatic glycogen were measured.Results:Compared with the blank control group,the weight-bearing swimming time and hypoxia-tolerant survival time of the low,middle and high dose groups was significantly increased(P<0.05).Whereas,the serum urea nitrogen levels and lactose content were significantly decreased(P<0.05).However,compared with the blank control group,the liver glycogen content of the middle and high dose groups was increased significantly(P<0.05),and there was no significant difference in the low dose group.Conclusion:The L-arginine complex preparation has an anti-fatigue function in mice. | Qian Tan Xiaodong Dong Junfeng Zhai Yaxian Gu Honghui Hao Wen Ren Chuanbao Gong Chengqiang Yin | 2019 | Proceedings of Anticancer Research2019，3，1： | 0 |

| 10 | A new FTO/TiO_(2)/PbO_(2)electrode for eco-friendly electrochemical determination of chemical oxygen demand显示文摘Eco-friendly chemical oxygen demand(COD)sensors are highly desired with respect to the importance of COD determination in environmental protection.In this work,a new FTO/TiO_(2)/PbO_(2)(FTO=fluorine-doped tin oxide)electrode was fabricated with a two-step method and used as an eco-friendly electrochemical COD sensor.The interlayer TiO_(2)was employed to strengthen the adhesion of PbO_(2)on the FTO substrates by providing a large TiO_(2)/PbO_(2)interface area.The effects of the factors including applied potential,supporting electrolyte concentration and stirring speed on the sensing performance were investigated.Under the optimized conditions,linear responses to the COD of water with different COD sources were achieved,and a linear range from 5 to 120 mg/L was obtained in the case of sucrose as the COD source.The relative standard deviations(RSD)were determined to be less than 9%for the glucose solutions with the COD of 7.5,12.5 and 17.5 mg/L.For real sample analysis,the obtained results were comparable with those measured with the conventional dichromate method,with a relative error less than 11%. | Lei Wang Yuehan Zhang Xiaoxuan Sun Yunhui Li Junfeng Zhai Shaojun Dong | 2023 | Nano Research2023，16，8： | 0 |
