| 1 | Corrosion mechanism of micro-arc oxidation treated biocompatible AZ31 magnesium alloy in simulated body fluid显示文摘The rapid degradation of magnesium(Mg) based alloys has prevented their further use in orthopedic trauma fixation and vascular intervention,and therefore it is essential to investigate the corrosion mechanism for improving the corrosion resistance of these alloys. In this work, the effect of applied voltage on the surface morphology and the corrosion behavior of micro-arc oxidation(MAO) with different voltages were carried out to obtain biocompatible ceramic coatings on AZ31 Mg alloy. The effects of applied voltage on the surface morphology and the corrosion behavior of MAO samples in the simulated body fluid(SBF) were studied systematically. Scanning electron microscope(SEM) and X-ray diffractometer(XRD)were employed to characterize the morphologies and phase compositions of coating before and after corrosion. The results showed that corrosion resistance of the MAO coating obtained at 250 V was better than the others in SBF. The dense layer of MAO coating and the corrosion precipitation were the key factors for corrosion behavior. The corrosion of precipitation Mg(OH)2and the calcium phosphate(Ca–P) minerals on the surface of MAO coatings could enhance their corrosion resistance effectively. In addition, the mechanism of MAO coated Mg alloys was proposed. | Ying Li Fang Lu Honglong Li Wenjun Zhu Haobo Pan Guoxin Tan Yonghua Lao Chengyun Ning Guoxin Ni | 2014 | Progress in Natural Science:Materials International2014，24，5： | 7 |
| 2 | Miura-origami-inspired electret/triboelectric power generator for wearable energy harvesting with water-proof capability显示文摘One of the critical issues for electret/triboelectric devices is the poor charge viability and stability in humid environments.Herein,we propose a new origami-inspired“W-tube”-shaped triboelectric nanogenerator(W-TENG)with two thin-film electrets folded based on Miura-origami.The Miura-origami fold is capable of transforming flat materials with large surface areas into reduced and compressed complex 3D structures with parallelogram tessellations.The triboelectric power generation components can thus be hermetically sealed inside the“W-tube”to avoid contact with the external humid environment.Furthermore,the elastic nature of the Miura-origami fold endows the proposed W-TENG device with excellent deformability,flexibility,and stretchability.Therefore,it is capable of harvesting kinetic energy from various directions and forms of movement,including horizontal pressing,vertical tapping,and lateral bending.The compact,light weight,and self-rebounding properties of the origami structure also make it convenient for integration into wearable devices.Various parameters of the W-TENG are intensively investigated,including the number of power generation units,original height of the device,acceleration magnitude,excitation direction,and water-proof capability.Triggered by hand tapping impulse excitation in the horizontal and vertical directions,the instantaneous open-circuit voltages can reach 791 V and 116 V with remarkable optimum powers of 691μW at 50MΩand 220μW at 35 MΩ,respectively.The outcomes of this work demonstrate the fusion of the ancient art of origami,material science,and energy conversion techniques to realize flexible,multifunctional,and water-proof TENG devices. | Kai Tao Haiping Yi Yang Yang Lihua Tang Zhaoshu Yang Jin Wu Honglong Chang Weizheng Yuan | 2020 | Microsystems & Nanoengineering2020，6，1： | 6 |

| 5 | Doping-free tandem white organic light-emitting diodes显示文摘Tandem white organic light-emitting diodes(WOLEDs) are of great research interest since they can greatly boost the performance compared with the single-unit counterparts. However, their structures are more complicated than those of single-unit OLEDs. Besides, to achieve high performance, the doping technology is required to tandem OLEDs, particularly for tandem WOLEDs, further complicating the structures. Herein, doping-free tandem WOLEDs, for the first time, have been demonstrated. By managing an effective doping-free charge generation layer to interconnect doping-free emitting layers/charge transport layers, high-performance doping-free tandem WOLEDs have been developed. The blueyellow device accomplishes the simplified structure/short fabrication time/reduced cost/high efficiency/low efficiency roll-off/low voltage/high luminance trade-off, which cannot be achieved by previous tandem WOLEDs. Remarkably, the efficiency(81.2 cd A^(-1)) is ~2-fold higher than the highest efficiency of previous doping-free WOLEDs and even higher than those of some best doping tandem WOLEDs. The maximum luminance is 44,886 cd m^(-2), which is the highest for doping-free WOLEDs.Besides, the blue-red device can exhibit a color rendering index(CRI) of 67, which is even higher than that of some representative three-color tandem WOLEDs. Such findings may not only represent a significant step for doping-free WOLEDs, but unlock a novel avenue that doping-free tandem WOLEDs are promising to achieve the simplicity and high performance trade-off. | Baiquan Liu Lei Wang Hong Tao Miao Xu Jianhua Zou Honglong Ning Junbiao Peng Yong Cao | 2017 | Science Bulletin2017，62，17： | 3 |
| 6 | Chip-based ion chromatography (chip-IC) with a sensitive five-electrode conductivity detector for the simultaneous detection of multiple ions in drinking water显示文摘The emerging need for accurate,efficient,inexpensive,and multiparameter monitoring of water quality has led to interest in the miniaturization of benchtop chromatography systems.This paper reports a chip-based ion chromatography(chip-IC)system in which the microvalves,sample channel,packed column,and conductivity detector are all integrated on a polymethylmethacrylate(PMMA)chip.A laser-based bonding technique was developed to guarantee simultaneous robust sealing between the homogeneous and heterogeneous interfaces.A five-electrode-based conductivity detector was presented to improve the sensitivity for nonsuppressed anion detection.Common anions(F^(−),Cl^(−),NO_(3)^(−),and SO _(4)^(2−))were separated in less than 8 min,and a detection limit(LOD)of 0.6 mg L^(−1) was achieved for SO_(4)^(2−).Tap water was also analyzed using the proposed chip-IC system,and the relative deviations of the quantified concentration were less than 10%when compared with that a commercial IC system. | Xiaoping Li Honglong Chang | 2020 | Microsystems & Nanoengineering2020，6，1： | 2 |
| 7 | Characterization of forced localization of disordered weakly coupled micromechanical resonators显示文摘The mode localization phenomenon of disordered weakly coupled resonators(WCRs)is being used as a novel transduction scheme to further enhance the sensitivity of micromechanical resonant sensors.In this paper,two novel characteristics of mode localization are described.First,we found that the anti-resonance loci behave as a linear function of the stiffness perturbation.The antiresonance behavior can be regarded as a new manifestation of mode localization in the frequency domain,and mode localization occurs at a deeper level as the anti-resonance approaches closer to the resonance.The anti-resonance loci can be used to identify the symmetry of the WCRs and the locations of the perturbation.Second,by comparing the forced localization responses of the WCRs under both the single-resonator-driven(SRD)scheme and the double-resonator-driven(DRD)scheme,we demonstrated that the DRD scheme extends the linear measurement scale while sacrificing a certain amount of sensitivity.We also demonstrated experimentally that the amplitude ratio-based sensitivity under the DRD scheme is approximately an order of magnitude lower than that under the SRD scheme,that is,the amplitude ratio-based sensitivity is−70.44%(Nm^(−1))^(−1) under the DRD scheme,while it is−785.6%(Nm^(−)1)^(−1) under the SRD scheme.These characteristics of mode localization are valuable for the design and control of WCR-based sensors. | Hemin Zhang Honglong Chang Weizheng Yuan | 2017 | Microsystems & Nanoengineering2017，3，1： | 2 |
| 8 | Recent advances in wireless epicortical and intracortical neuronal recording systems显示文摘An implantable brain-computer interface(BCI)has proven to be effective in the field of sensory and motor function restoration and in the treatment of neurological disorders.Using a BCI recording system,we can transform current methods of human interaction with machines and the environment,especially to help those with cognitive and mobility disabilities regain mobility and reintegrate into society.However,most reported work has focused on a simple aspect of the whole system,such as electrodes,circuits,or data transmission,and only a very small percentage of systems are wireless.A miniature,lightweight,wireless,implantable microsystem is key to realizing long-term,real-time,and stable monitoring on freely moving animals or humans in their natural conditions.Here,we summarize typical wireless recording systems,from recording electrodes,processing chips and controllers,wireless data transmission,and power supply to the system-level package for either epicortical electrocorticogram(ECoG)or intracortical local field potentials(LFPs)/spike acquisition,developed in recent years.Finally,we conclude with our vision of challenges in next-generation wireless neuronal recording systems for chronic and safe applications. | Bowen JI Zekai LIANG Xichen YUAN Honglai XU Minghao WANG Erwei YIN Zhejun GUO Longchun WANG Yuhao ZHOU Huicheng FENG Honglong CHANG Jingquan LIU | 2022 | Science China(Information Sciences)2022，65，4： | 2 |

| 18 | Alloy-Electrode-Assisted High-Performance Enhancement-Type Neodymium-Doped Indium-Zinc-Oxide Thin-Film Transistors on Polyimide Flexible Substrate显示文摘Flexible thin-film transistors with high current-driven capability are of great significance for the next-generation new display technology.The effect of a Cu-Cr-Zr(CCZ)copper alloy source/drain(S/D)electrode on flexible amorphous neodymiumdoped indium-zinc-oxide thin-film transistors(NdIZO-TFTs)was investigated.Compared with pure copper(Cu)and aluminum(Al)S/D electrodes,the CCZ S/D electrode changes the TFT working mode from depletion mode to enhancement mode,which is ascribed to the alloy-assisted interface layer besides work function matching.X-ray photoelectron spectroscopy(XPS)depth profile analysis was conducted to examine the chemical states of the contact interface,and the result suggested that chromium(Cr)oxide and zirconium(Zr)oxide aggregate at the interface between the S/D electrode and the active layer,acting as a potential barrier against residual free electron carriers.The optimal NdIZO-TFT exhibited a desired performance with a saturation mobility(μsat)of 40.3 cm^(2)·V-1·s^(-1),an Ion/Ioff ratio of 1:24×10^(8),a subthreshold swing(SS)value of 0.12 V·decade^(-1),and a threshold voltage(Vth)of 0.83 V.This work is anticipated to provide a novel approach to the realization of highperformance flexible NdIZO-TFTs working in enhancement mode. | Kuankuan Lu Rihui Yao Wei Xu Honglong Ning Xu Zhang Guanguang Zhang Yilin Li Jinyao Zhong Yuexin Yang Junbiao Peng | 2021 | Research2021，，1： | 1 |
