| 2 | Bioinspired Functional Surfaces for Medical Devices显示文摘Medical devices are a major component of precision medicine and play a key role in medical treatment,particularly with the rapid development of minimally invasive surgery and wearable devices.Their tissue contact properties strongly affect device performance and patient health(e.g.,heat coagulation and slipperiness on surgical graspers).However,the design and optimization of these device surfaces are still indistinct and have no supporting principles.Under such conditions,natural surfaces with various unique functions can provide solutions.This review summarizes the current progress in natural functional surfaces for medical devices,including ultra-slipperiness and strong wet attachment.The underlying mechanisms of these surfaces are attributed to their coupling effects and featured micronano structures.Depending on various medical requirements,adaptable designs and fabrication methods have been developed.Additionally,various medical device surfaces have been validated to achieve enhanced contact properties.Based on these studies,a more promising future for medical devices can be achieved for enhanced precision medicine and human health. | Liwen Zhang Guang Liu Yurun Guo Yan Wang Deyuan Zhang Huawei Chen | 2022 | Chinese Journal of Mechanical Engineering2022，35，3： | 1 |
| 3 | Gas Permeability and Free Volume Hole Properties of Interpenetrating Polymer Network Studied by Positrons显示文摘A series of polyurethane/epoxy resin interpenetrating polymer networks (PU/ER IPN) were studied by positron annihilation lifetime spectroscopy (PALS). The effects of epoxy resin type and content on the free volume properties in IPN were investigated. We found that in PU/ER IPN, the free volume hole size and fractional free volume showed a negative deviation due to closer segmental chain packing through some chemical bonding between PU and epoxy resin. Direct relationship between the gas permeability and the free volume has been established based on the free volume theory. Experimental results revealed that the free volume plays an important role in determining the gas diffusion and permeability. | QI Ning GONG Wei WANG Zhifen WANG Bo YANG Yurun HU Chunpu | 2007 | Wuhan University Journal of Natural Sciences2007，12，2： | 0 |
| 4 | Dynamic Modeling and Sensitivity Analysis for an MEA-Based CO_(2) Capture Absorber显示文摘The absorber is the key unit in the post-combustion monoethanolamine(MEA)-based carbon dioxide(CO_(2))capture process.A rate-based dynamic model for the absorber is developed and validated using steady-state experimental data reported in open literature.Sensitivity analysis is performed with respect to important model parameters associated with the reaction,mass transport and phy-sical property relationships.Then,a singular value decomposition(SVD)-based subspace parameter estimation method is proposed to improve the model accu-racy.Finally,dynamic simulations are carried out to investigate the effects of the feed rate of lean MEA solution and the flue inlet conditions.Simulation results indicate that the established dynamic model can reasonably reflect the physical behavior of the absorber.Some new insights are gained from the simulation results. | Hongwei Guan Lingjian Ye Yurun Wang Feifan Shen Yuchen He | 2023 | Intelligent Automation & Soft Computing2023，，6： | 0 |
| 5 | Dielectric properties of porous SiC/Si3N4 ceramics by polysilazane immersion-pyrolysis显示文摘The SiC nanotubes were synthesized on porous Si3N4 matrix by polysilazane immersion-pyrolysis. The β-SiC and free C contents increased with the increasing dipping times, which cause some clear vibration and loss peaks of the dielectric constant patterns emerged at around 12.9 GHz and 14.7 GHz in the samples of 20 wt% and 30 wt%benzoic acid, respectively. The reflectivity of the obtained ceramics were -7 dB ^-10 dB from the frequency of 8 GHz–18 GHz, which means that the amount of 80%–90% electromagnetic wave could be attenuated. The ceramics containing 40 wt% benzoic acid showed the high loss, low reflectivity and a wide absorbing band,indicating the high absorbing efficiency and good dielectric properties. | Xiao Lin Hongyu Gong Yujun Zhang Jianqiang Bi Yurun Feng Yu Liu Shan Wang | 2019 | Progress in Natural Science:Materials International2019，29，2： | 0 |
| 6 | Four-junction AlGaAs/GaAs laser power converter显示文摘Four-junction AlGaAs/GaAs laser power converters (LPCs) with n^+-Ga As/p^+-Al_(0.37)Ga_(0.63)As hetero-structure tunnel junctions (TJs) have been designed and grown by metal-organic chemical vapor deposition(MOCVD) for converting the power of 808 nm lasers. A maximum conversion efficiency ηc of 56.9% ± 4% is obtained for cells with an aperture of 3.14 mm^2 at an input laser power of 0.2 W, while dropping to 43.3% at 1.5 W.Measured current–voltage (I–V) characteristics indicate that the performance of the LPC can be further improved by increasing the tunneling current density of TJs and optimizing the thicknesses of sub-cells to achieve current matching in LPC. | Jie Huang Yurun Sun Yongming Zhao Shuzhen Yu Jianrong Dong Jiping Xue Chi Xue Jin Wang Yunqing Lu Yanwen Ding | 2018 | Journal of Semiconductors2018，39，4： | 0 |
| 7 | The structures of noncrystalline rocks显示文摘The structural studies of noncrystalline rocks by total radial distribution function (RDF) which was derived from the wide angular X-ray scattering (WAXS) have been reported. In order to make a further study of the structural features shown by RDF, the unsymmetric peaks in total RDF were separated into the approximately symmetric peaks by the multi-peaks separation processing. By analyzing the relationship of the peak parameters with the compositions, the information of further structures has been discussed. | CHEN Jizhou WANG Junqiao Bl Yurun LIU Pingan | 2000 | Chinese Science Bulletin2000，45，9： | 0 |
