| 2 | Fast nanoparticle sizing by image dynamic light scattering显示文摘In this paper,an image dynamic light scattering method for nanoparticle sizing is introduced.The spatial distribution of the scattered lights from nanoparticles undergoing Brownian motion was captured at a high frame rate by a digital camera within one second,which is considerably faster than the conventional photon correlation spectroscopy method.The captured series of photographs were meshed into thousands of small units for calculating the intensity autocorrelation functions in parallel.Experimental results from the measurements of three reference nanoparticle samples(27,80,and 352 nm in diameters)demonstrated the feasibility of this method. | Chengze Xu Xiaoshu Cai Jie Zhang Lili Liu | 2015 | Particuology2015，13，2： | 3 |
| 3 | Boundary-aware texture region segmentation from manga显示文摘Due to the lack of color in manga(Japanese comics), black-and-white textures are often used to enrich visual experience. With the rising need to digitize manga, segmenting texture regions from manga has become an indispensable basis for almost all manga processing, from vectorization to colorization. Unfortunately, such texture segmentation is not easy since textures in manga are composed of lines and exhibit similar features to structural lines(contour lines). So currently, texture segmentation is still manually performed, which is labor-intensive and time-consuming. To extract a texture region, various texture features have been proposed for measuring texture similarity, but precise boundaries cannot be achieved since boundary pixels exhibit different features from inner pixels. In this paper, we propose a novel method which also adopts texture features to estimate texture regions. Unlike existing methods, the estimated texture region is only regarded an initial, imprecise texture region. We expand the initial texture region to the precise boundary based on local smoothness via a graph-cut formulation. This allows our method to extract texture regions with precise boundaries. We have applied our method to various manga images and satisfactory results were achieved in all cases. | Xueting Liu Chengze Li Tien-Tsin Wong | 2017 | Computational Visual Media2017，3，1： | 2 |
| 4 | Degradation of tetracycline hydrochloride by ultrafine TiO_(2) nanoparticles modified g-C_(3)N_(4) heterojunction photocatalyst:Influencing factors,products and mechanism insight显示文摘The unique heterojunction photocatalyst of graphite carbon nitride (g-C_(3)N_(4)) modified ultrafine TiO_(2) (g-C_(3)N_(4)/TiO_(2)) was successfully fabricated by electrochemical etching and co-annealing method. However, the effects of various environmental factors on the degradation of TC by g-C_(3)N_(4)/TiO_(2) and the internal reaction mechanism are still unclear. In this study, the effects of initial pH, anions, and cations on the photocatalytic degradation of tetracycline hydrochloride (TC) by g-C_(3)N_(4)/TiO_(2) were systematically explored, and the scavenging experiment and intermediate detection were conducted to better reveal the mechanism on photocatalytic degradation of TC. The results showed that the removal efficiency of photocatalytic degradation of TC by g-C_(3)N_(4)/TiO_(2) could reach 99.04% under Xenon lamp irradiation within 120 min. The unique g-C_(3)N_(4)/TiO_(2) heterojunction photocatalyst showed excellent photocatalytic performance for the degradation of TC at pH 3~7, and possesses outstanding anti-interference ability to NO_(3)^(-), Cl^(-), Na^(+), Ca^(2+) and Mg^(2+) ions in natural waters during the photocatalytic degradation TC process. Superoxide radicals (O_(2)^(·-)) and hydroxyl radicals (^(·)OH) were proved as the main reactive species for TC degradation, and the possible mechanism of the unique photocatalytic system for g-C_(3)N_(4)/TiO_(2) was also proposed. The above results can provide a reliable basis and theoretical guidance for the design and application of visible photocatalyst with high activity to degrade the actual wastewater containing TC. | Bin Zhang Xu He Chengze Yu Guocheng Liu Dong Ma Chunyue Cui Qinghua Yan Yingjie Zhang Guangshan Zhang Jun Ma Yanjun Xin | 2022 | Chinese Chemical Letters2022，33，3： | 2 |
| 5 | The influence of microtexture on the formation mechanism of nodules in Zircaloy-4 alloy tube显示文摘Corrosion re sistance of Zircaloy-4 alloy tube in superheated steam at 673 K/10.3 MPa is anisotropic.A part of the surface undergoes uniform corrosion while the other suffers nodular corrosion.Narrow and wide nodules are observed after an exposure period of 3 and 30 days,respectively.A new matrix transformation method is established in order to study the formation mechanism of nodules in the cross-section(CS) of Zircaloy-4 alloy tube using the EBSD technique,while the CS perpendicular to axial direction(AD).The results reveal that the microtexture is a key factor behind the two types of corrosion.Furthermore,the oxide layers grow anisotropically over the corroded surface.A thick oxide layer forms over the nodular corrosion region on the grains with c-axis oriented in the range of 40° around tangential direction(TD),whereas a thin oxide layer over the uniform corrosion region is detected on the grains with c-axis oriented in the range of 68° around TD.In short,the anisotropic growth of oxide layer was caused by the change of microtexture of the Zr-4 alloy tube,and this anisotropic growth of oxide layer contributed to the nodules formation. | Yingdong Zhang Fusen Yuan Fuzhou Han Muhammad Ali Wenbin Guo Geping Li Chengze Liu Hengfei Gu | 2020 | Journal of Materials Science & Technology2020，47，12： | 2 |

| 8 | Nano-refinement of the face-centered cubic Zr(Fe,Cr)_(2)secondary phase particles in Zircaloy-4 alloy via localized-shearing/bending-driven fracture under high-temperature compression显示文摘Nanoparticles are extensively introduced to improve the mechanical,physical,and chemical properties of alloys.In the present study,the underlying nano-refinement mechanisms of face-centered cubic Zr(Fe,Cr)_(2)secondary phase particles(SPPs)that precipitated in Zircaloy-4 alloy under high-temperature compression were investigated in detail by utilizing high-resolution transmission electron microscopy(HRTEM)and conventional TEM techniques.The frequently observed Zr(Fe,Cr)_(2)SPPs were incoherent with the matrix and exhibited brittle fracture behaviors without measurable plasticity.HRTEM observations revealed two mechanisms underlying the nano-refinement of incoherent micro-sized SPPs via localized shear fracture on{11¯2}SPP and nanoprecipitate-assisted bending fracture,respectively.The latter was,for the first time,found to occur when the movements of large SPPs were blocked by nanometer-sized SPP during alloy deformation.Accordingly,two force models were proposed to visualize their potential nano-refinement processes.The knowledge attained from this study sheds new light on the deformation behaviors of Zr(Fe,Cr)_(2)SPPs and their associated size refinement mechanisms under high-temperature compression,and is expected to greatly benefit the process optimization of zirconium alloys to achieve precipitate nano-refinement. | Fuzhou Han Geping Li Fusen Yuan Wenbin Guo Jie Ren Qichen Wang Yingdong Zhang Ali Muhammad Chengze Liu Hengfei Gu | 2023 | Journal of Materials Science & Technology2023，，34： | 0 |
| 9 | Reference-guided structure-aware deep sketch colorization for cartoons显示文摘Digital cartoon production requires extensive manual labor to colorize sketches with visually pleasant color composition and color shading.During colorization,the artist usually takes an existing cartoon image as color guidance,particularly when colorizing related characters or an animation sequence.Reference-guided colorization is more intuitive than colorization with other hints,such as color points or scribbles,or text-based hints.Unfortunately,reference-guided colorization is challenging since the style of the colorized image should match the style of the reference image in terms of both global color composition and local color shading.In this paper,we propose a novel learning-based framework which colorizes a sketch based on a color style feature extracted from a reference color image.Our framework contains a color style extractor to extract the color feature from a color image,a colorization network to generate multi-scale output images by combining a sketch and a color feature,and a multi-scale discriminator to improve the reality of the output image.Extensive qualitative and quantitative evaluations show that our method outperforms existing methods,providing both superior visual quality and style reference consistency in the task of reference-based colorization. | Xueting Liu Wenliang Wu Chengze Li Yifan Li Huisi Wu | 2022 | Computational Visual Media2022，8，1： | 0 |
| 10 | Piezoelectric bimorph MEMS speakers显示文摘One of the key requirements for MEMS speakers is to increase the sound pressure level(SPL)while keeping the size as small as possible.In this paper we present a MEMS speaker based on piezoelectric bimorph cantilevers that produces a higher SPL than conventional unimorph cantilever speakers.The active diaphragm size is 1.4×1.4 mm^(2).The bimorph cantilevers are connected in parallel to make full use of the actuation voltage.At 1 kHz,the measured SPL reached 73 dB and the peak SPL reached 102 dB at the resonance frequency of 10 kHz in a 711 ear simulator under a driving voltage of 10 V_(rms).The total harmonic distortion of the MEMS speaker was less than 3%in the range from 100 Hz to 20 kHz.Although the absolute SPL was not the highest,this work provides a better SPL for all piezoelectric MEMS speakers. | Yiming Lang Chengze Liu Ahmed Fawzy Chen Sun Shaobo Gong Menglun Zhang | 2022 | Nanotechnology and Precision Engineering2022，5，3： | 0 |
| 11 | A new type face-centered cubic zirconium phase in pure zirconium显示文摘So far,only two orientation relationships(OR)between hexagonal close-packed(HCP)(αphase)and facecentered cubic(FCC)structures in zirconium and titanium alloys have been reported.Here a new type FCC phase(named γ phase)with OR:<11■0>_(α)‖<100>_(γ) and{0001}_(α)‖{002}_(γ) was observed for the first time in annealed pure zirconium by means of transmission electron microscopy(TEM)technique.The α→γ phase transformation can be accomplished via expansion along[1■00]direction and slip of Shockley partial dislocation with 1/3[1■00]on(0001)basal planes. | Fusen Yuan Geping Li Fuzhou Han Yingdong Zhang Ali Muhammad Wenbin Guo Jie Ren Chengze Liu Hengfei Gu Gaihuan Yuan | 2021 | Journal of Materials Science & Technology2021，，22： | 0 |

| 13 | A giant central red disk galaxy at redshift z=0.76:Challenge to theories of galaxy formation显示文摘We report a giant red central disk galaxy in the XMM-LSS north region. The region is covered with a rich variety of multi-band photometric and spectroscopic observations. Using the photometric data of the Canada-France-Hawaii Telescope Legacy Survey(CFHTLS) and spectroscopic observation of the baryon oscillation spectroscopic survey(BOSS), we find that the galaxy has a stellar mass of ~1011.6 M⊙. The galaxy has a red color and has an old stellar population, and thus its star formation has stopped.With the photometric image data of the Hyper Suprime-Cam(HSC) Subaru Strategic Program, we demonstrate that its luminosity profile is perfectly described by a Sérsic form with n=1.22 consistent with that of a disk. We also analyze its environment based on the VIMOS Public Extragalactic Redshift Survey(VIPERS) photometric catalog, and find that its close neighbors are all less massive, indicating that our observed galaxy is sitting at the center of its dark matter host halo. Existence of such a giant red central disk galaxy seriously challenges the current standard paradigm of galaxy formation, as there is no known physical mechanism to explain the quenching of its star formation. This conclusion is supported by state-of-the-art hydrodynamical simulations of galaxy formation. | Kun Xu ChengZe Liu YiPeng Jing Marcin Sawicki Stephen Gwyn | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，7： | 0 |
| 14 | Deformation twinning in octahe dron-base d face-centere d cubic metallic structures:Localized shear-force dipoles drive atomic displacements显示文摘Twinning is found to impart favorable mechanical,physical and chemical properties to nanostructured materials.Deformation twinning prevails in face-centered cubic(FCC)nanocrystalline materials upon loading.In FCC structures,the<112>{111}deformation twinning is traditionally believed to nucleate and grow through layer-by-layer emission of 1/6<112>Shockley partial dislocations on consecutive{111}planes.We report that deformation twinning is able to occur in crystalline(Fe,Nb)_(23)Zr_(6)nanoparticles(NPs)that have a large Mn 23 Th 6-type FCC structure with a Zr-octahedron as a motif.Based on direct atomic-scale observations,we discover a new zero-net-strain path for the<112>{111}deformation twin-ning in FCC structures.To form a[¯1¯12]/(111)twin,for example,short(¯1¯11)planes within two adjacent(111)plane layers in the repeated three-layer sequence of(111)planes are shear deformed continuously by a shear-force dipole along the[11¯2]direction like a domino effect,whereas the other(111)plane in the repeated sequence remains intact.In addition,a loading criterion for deformation twinning of a FCC NP under uniaxial compression is proposed based on our observations.Our work here not only extends the fundamental understanding on deformation twinning in FCC structures,but also opens up studies of deformation behaviors in a class of Mn 23 Th 6-type FCC materials. | Hengfei Gu Chengze Liu Fusen Yuan Fuzhou Han Yingdong Zhang Muhammad Ali Wenbin Guo Jie Ren Lifeng Zhang Songquan Wu Geping Li | 2022 | Journal of Materials Science & Technology2022，，31： | 0 |
| 15 | Formation of Face‑Centered Cubic Phase in Ti35 Alloy Under In Situ Heating Transmission Electron Microscopy显示文摘A thermally induced hexagonal close-packed(HCP)to face-centered cubic(FCC)phase transition was investigated in anα-type Ti35 alloy with twinned structure by in situ heating transmission electron microscopy(TEM)and ab initio calculations.TEM observations indicated that the HCP to FCC phase transition occurred both within matrix/twin and at the twin boundaries in the thinner region of the TEM film,and the FCC-Ti precipitated as plates within the matrix/twin,while as equiaxed cells at twin boundaries.The crystallographic orientation relationship between HCP-Ti and FCC-Ti can be described as:{111}FCC//{0002}HCP and<110>FCC//<1210>HCP.The HCP to FCC phase transition was accomplished by forming an intermediate state with a BB stacking sequence through the slip of partial dislocations.The formation of such FCC-Ti may be related to the thermal stress and temperature.Ab initio calculations showed that the formation of FCC-Ti may also be related to the contamination of interstitial atoms such as oxygen. | Jianan Hu Mengmeng Yang Wenlong Xiao Hao Wang Dehai Ping Chengze Liu Shewei Xin Songquan Wu Kai Zhang Yi Yang Lai‑Chang Zhang Aijun Huang | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，3： | 0 |
