| 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 | 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 | 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 |

| 17 | Structure tailorable triple-phase and pure double-polar-phase flexible IF-WS_(2)@poly(vinylidene fluoride)nanocomposites with enhanced electrical and mechanical properties显示文摘A new low-cost high-permittivity flexible nanocomposite consisting of a polyvinylidene fluoride(PVDF)matrix and fullerene-like tungsten disulfide nanoparticle(IF-WS2 NP)filler was fabricated via a simple solution route.A comprehensive investigation by X-ray diffraction,attenuated total reflection-infrared spectroscopy,and differential scanning calorimetry(DSC)showed that 0.5e1 vol% of IF-WS_(2) induced a nonpolar α-phase to coexisting triple-phase transition in PVDF,whereas a slightly higher loading of 2 vol% induced pure double-polar β- and γ-phases.These results indicate that the structure and properties of the fabricated nanocomposite are easily tailorable.DSC during heating and cooling cycles and morphology observations further indicated that a polar phase was induced by the nucleation effect of the IF-WS2 NPs and electrostatic interactions.As a consequence of the multiphase coexistence and structure homogeneity,nanocomposites with approximately 0.5-1 vol% of IF-WS_(2) NPs showed enhanced dielectric and energy-storage performance as well as enhanced tensile strength and elongation.The new phase-tailorable nanocomposites with balanced properties are promising for applications as energystorage capacitors,piezoelectric sensors,and other flexible multifunctional components.The results of this study will serve to deepen the understanding of the polymer polymorph and provide directions on new routes for fabrication of smart materials. | Dong Guo Kai Cai Pingye Deng Guoning Si Liangying Sun Fahui Chen Honglong Ning Li Jin Jingtao Ma | 2020 | Journal of Materiomics2020，6，3： | 0 |
| 18 | Neglected acidity pitfall:boric acid-anchoring hole-selective contact for perovskite solar cells显示文摘The spontaneous formation of self-assembly monolayer(SAM) on various substrates represents an effective strategy for interfacial engineering of optoele ctronic devices.Hole-selective SAM is becoming popular among high-performance inverted perovskite solar cells(PSCs),but the presence of strong acidic anchors(such as-PO_(3)H_(2)) in state-of-the-art SAM is detrimental to device stability.Herein,we report for the first time that acidity-weakened boric acid can function as an alternative anchor to construct efficient SAM-based hole-sele ctive contact(HSC) for PSCs.Theoretical calculations reve al that boric acid spontaneously chemisorbs onto indium tin oxide(ITO) surface with oxygen vacancies facilitating the adsorption progress.Spectroscopy and electrical measurements indicate that boric acid anchor significantly mitigates ITO corrosion.The excess boric acid containing molecules improves perovskite deposition and results in a coherent and well-passivated bottom interface,which boosts the fill factor(FF) performance for a variety of perovskite compositions.The optimal boric acid-anchoring HSC(MTPA-BA) can achieve power conversion efficiency close to 23% with a high FF of 85.2%.More importantly,the devices show improved stability:90% of their initial efficiency is retained after 2400 h of storage(ISOS-D-1) or 400 h of operation(ISOS-L-1),which are 5-fold higher than those of phosphonic acid SAM-based devices.Acidity-weakened boric acid SAMs,which are friendly to ITO,exhibits well the great potential to improve the stability of the interface as well as the device. | Huanxin Guo Cong Liu Honglong Hu Shuo Zhang Xiaoyu Ji Xiao-Ming Cao Zhijun Ning Wei-Hong Zhu He Tian Yongzhen Wu | 2023 | National Science Review2023，10，5： | 0 |
