| 1 | 3D Hessian deconvolution of thick light-sheet z-stacks for high-contrast and high-SNR volumetric imaging显示文摘Due to its ability of optical sectioning and low phototoxicity,z-stacking light-sheet microscopy has been the tool of choice for in vivo imaging of the zebrafish brain.To image the zebrafish brain with a large field of view,the thickness of the Gaussian beam inevitably becomes several times greater than the system depth of field(DOF),where the fluorescence distributions outside the DOF will also be collected,blurring the image.In this paper,we propose a 3D deblurring method,aiming to redistribute the measured intensity of each pixel in a light-sheet image to in situ voxels by 3D deconvolution.By introducing a Hessian regularization term to maintain the continuity of the neuron dis-tribution and using a modified stripe removal algorithm,the reconstructed z stack images exhibit high contrast and a high signal-to-noise ratio.These performance characteristics can facilitate subsequent processing,such as 3D neuron registration,segmentation,and recognition. | ZHE ZHANG DONGZHOU GOU FAN FENG RUYI ZHENG KE DU HONGRUN YANG GUANGYI ZHANG HUITAO ZHANG LOUIS TAO LIANGYI CHEN HENG MAO | 2020 | Photonics Research2020，8，6： | 1 |
| 2 | Li_(x)Na_(2-x)W_(4)O_(13) nanosheet for scalable electrochromic device显示文摘The printed electronics technology can be used to efficiently construct smart devices and is dependent on functional inks containing well-dispersed active materials.Two-dimensional(2D)materials are promising functional ink candidates due to their superior properties.However,the majority 2D materials can disperse well only in organic solvents or in surfactant-assisted water solutions,which limits their applications.Herein,we report a lithium(Li)-ion exchange method to improve the dispersity of the Na_(2)W_(4)O_(13) nanosheets in pure water.The Li-ion-exchanged Na_(2)W_(4)0_(13)(Li_(x)Na_(2-x)W_(4)O_(13))nanosheets show highly stable dispersity in water with a zeta potential of-55 mV.Moreover,this aqueous ink can be sprayed on various substrates to obtain a uniform LixNa2_xW4O13 nanosheet film,exhibiting an excellent electrochromic performance.A complementary electrochromic device containing a Li_(x)Na_(2-x)W_(4)O_(13) nanosheet film as an electrochromic layer and Prussian white(PW)as an ion storage layer exhibits a large optical modulation of 75% at 700 nm,a fast switching response of less than 2 s,and outstanding cyclic stability.This Na2W4Oi3-based aqueous ink exhibits considerable potential for fabricating large-scale and flexible electrochromic devices,which would meet the practical application requirements. | Yucheng LU Xin YANG Hongrun JIN Kaisi LIU Guoqun ZHANG Liang HUANG Jia LI Jun ZHOU | 2021 | Frontiers of Optoelectronics2021，14，3： | 0 |
| 3 | Cobalt doping boosted electrocatalytic activity of CaMn3O6 for hydrogen evolution reaction显示文摘The development of earth-abundant-metal-based electrocatalysts with high efficiency and long-term stability for hydrogen evolution reaction(HER)is crucial for the clean and renewable energy application.Herein,we report a molten-salt method to synthesize Co-doped CaMn_(3)O_(6)(CMO)nanowires(NWs)as effective electrocatalyst for HER.The as-obtained CaMn_(3-x)Co_(x)O_(6)(CMCO)exhibits a small onset overpotential of 70 mV,a required overpotential of 140 mV at a current density of 10 mA·cm^(-2),a Tafel slope of 39 mV·dec^(-1)in 0.1 M HClO_(4),and a satisfying long-term stability.Experimental characterizations combined with density functional theory(DFT)calculations demonstrate that the obtained HER performance can be attributed to the Co-doping which altered CMO’s surface electronic structures and properties.Considering the simplicity of synthesis route and the abundance of the pertinent elements,the synthesized CMCO shows a promising prospect as a candidate for the development of earth-abundant,metal-based,and cost-effective electrocatalyst with superior HER activity.Our results also establish a strategy of rational design and construction of novel electrocatalyst toward HER by tailoring band structures of transition metal oxides(TMOs). | Qun Li Kaisi Liu Siwei Gui Jiabin Wu Xiaogang Li Zaifang Li Hongrun Jin Hui Yang Zhimi Hu Wenxi Liang Liang Huang | 2022 | Nano Research2022，15，4： | 0 |
