| 1 | Design of a hexagonal air-coupled capacitive micromachined ultrasonic transducer for air parametric array显示文摘An air parametric array can generate a highly directional beam of audible sound in air,which has a wide range of applications in targeted audio delivery.Capacitive micromachined ultrasonic transducer(CMUTs)have great potential for air-coupled applications,mainly because of their low acoustic impedance.In this study,an air-coupled CMUT array is designed as an air parametric array.A hexagonal array is proposed to improve the directivity of the sound generated.A finite element model of the CMUT is established in COMSOL software to facilitate the choice of appropriate structural parameters of the CMUT cell.The CMUT array is then fabricated by a wafer bonding process with high consistency.The performances of the CMUT are tested to verify the accuracy of the finite element analysis.By optimizing the component parameters of the bias-T circuit used for driving the CMUT,DC and AC voltages can be effectively applied to the top and bottom electrodes of the CMUT to provide efficient ultrasound transmission.Finally,the prepared hexagonal array is successfully used to conduct preliminary experiments on its application as an air parametric array. | Xiaoli Zhang Hui Zhang Dachao Li | 2021 | Nanotechnology and Precision Engineering2021，4，1： | 4 |
| 2 | Superconducting quantum computing: a review显示文摘Over the last two decades,tremendous advances have been made for constructing large-scale quantum computers.In particular,quantum computing platforms based on superconducting qubits have become the leading candidate for scalable quantum processor architecture,and the milestone of demonstrating quantum supremacy has been first achieved using 53 superconducting qubits in 2019.In this study,we provide a brief review on the experimental efforts towards the large-scale superconducting quantum computer,including qubit design,quantum control,readout techniques,and the implementations of error correction and quantum algorithms.Besides the state of the art,we finally discuss future perspectives,and which we hope will motivate further research. | He-Liang HUANG Dachao WU Daojin FAN Xiaobo ZHU | 2020 | Science China(Information Sciences)2020，63，8： | 3 |
| 3 | Review of minimally invasive continuous glucose monitoring technology & instruments显示文摘Continuous blood glucose monitoring is important for the diagnosis,treatment,and study of diabetes. many organizations have been working on this subject in recent two decades. Glucose concentration in interstitial fluid is closely related to the blood glucose levels. Minimally invasive continuous blood glucose monitoring technology based on the glucose detection in interstitial fluid develops rapidly and gets more and more attentions from the patients and the doctors,due to its instantaneous real-time display of glucose level,'24/7'coverage,and the ability to characterize glycemic variability. According to the different detection methods,most of the continuous glucose monitoring technology could be divided into two kinds: subcutaneous implantation method and transdermal extraction method. This paper review s the recent development of minimally invasive blood glucose monitoring technology and instruments. The mainly remained challenges and related research directions are presented as well. | YU Haixia LI Dachao XU Kexin | 2016 | Instrumentation2016，3，4： | 2 |

| 5 | A Rubik’s microfluidic cube显示文摘A Rubik’s cube as a reconfigurable microfluidic system is presented in this work.Composed of physically interlocking microfluidic blocks,the microfluidic cube enables the on-site design and configuration of custom microfluidics by twisting the faces of the cube.The reconfiguration of the microfluidics could be done by solving an ordinary Rubik’s cube with the help of Rubik’s cube algorithms and computer programs.An O-ring-aided strategy is used to enable self-sealing and the automatic alignment of the microfluidic cube blocks.Owing to the interlocking mechanics of cube blocks,the proposed microfluidic cube exhibits good reconfigurability and robustness in versatile applications and proves to be a promising candidate for the rapid deployment of microfluidic systems in resource-limited settings. | Xiaochen Lai Zhi Shi Zhihua Pu Penghao Zhang Xingguo Zhang Haixia Yu Dachao Li | 2020 | Microsystems & Nanoengineering2020，6，1： | 1 |

| 7 | Effect of Pingan Fang, a Traditional Chinese Medicine compound, on behavioral sensitization and conditioned place preference induced by ethanol in mice显示文摘OBJECTIVE:To observe the effect of Pingan Fang(PG)on behavioral sensitization and conditioned place preference(CPP)induced by ethanol in mice,and to determine the intervention mechanism of PG on alcohol addiction.METHODS:A behavioral sensitization mouse model induced by ethanol was established to observe the effect of PG on the development and expression of behavioral sensitization induced by ethanol by recording the spontaneous activity of mice.The resident time of mice in a white box was measured to evaluate the effect of PG on developing CPP induced by ethanol.Concentrations of dopamine(DA),Glutamate(Glu),and?-aminobutyric acid(GABA)in the corresponding mesolimbic region of mice were determined by enzyme-linked immunosorbent assay.RESULTS:Although PG did not alter spontaneous activity in mice,it reduced the growth of spontaneous activity stimulated by ethanol.The residence time in the white box after-ethanol-training of mice in CPP experiments was decreased.CONCLUSION:Our data suggested that PG blocked the development and expression of behavioral sensitization induced by ethanol and the development of CPP in mice.The mechanism might be related to the decreased content of DA and Glu and increased content of GABA in the mesolimbic dopamine system.This suggests that PG might be useful for the prevention and treatment of alcohol addiction. | Jia Lingyan Li Yibei Hu Xiaoyu Lin Wu Wen Dachao Zhong Sen | 2016 | Journal of Traditional Chinese Medicine2016，36，2： | 1 |
