2Multiplexed Five-Color Molecular Imaging of Cancer Cells and Tumor Tissues with Carbon Nanotube Raman Tags in the Near-Infrared显示文摘Single-walled carbon nanotubes(SWNTs)with five different C13/C12 isotope compositions and well-separated Raman peaks have been synthesized and conjugated to five targeting ligands in order to impart molecular specificity.Multiplexed Raman imaging of live cells has been carried out by highly specific staining of cells with a five-color mixture of SWNTs.Ex vivo multiplexed Raman imaging of tumor samples uncovers a surprising up-regulation of epidermal growth factor receptor(EGFR)on LS174T colon cancer cells from cell culture to in vivo tumor growth.This is the first time five-color multiplexed molecular imaging has been performed in the near-infrared(NIR)region under a single laser excitation.Near zero interfering background of imaging is achieved due to the sharp Raman peaks unique to nanotubes over the low,smooth autofluorescence background of biological species.Zhuang Liu Scott Tabakman Sarah Sherlock Xiaolin Li Zhuo Chen Kaili Jiang Shoushan Fan Hongjie Dai 2010Nano Research2010,3,3:11
3A self-recovery fragile watermarking scheme for image authentication with superior localization显示文摘To address the problems of the inferior localization and high probability of false rejection in existing self-recovery fragile watermarking algorithms,this paper pro-poses a new self-recovery fragile watermarking scheme with superior localization,and further discusses the probability of false rejection (PFR) and the probability of false acceptance (PFA) of the proposed scheme. Moreover,four measurements are defined to evaluate the quality of a recovered image. In the proposed algorithm,the original image is divided into 2×2 blocks to improve localization precision and de-crease PFR under occurrence of random tampering. The PFR under occurrence of region tampering can be effectively decreased by randomly embedding the water-mark of each block in conjunction with a novel method of tamper detection. Com-pared with the current self-recovery fragile watermarking algorithms,the proposed scheme not only resolves the tamper detection problem of self-embedding water-marking,but also improves the robustness against the random tampering of self-embedding watermarking. In addition,the subjective measurements are pro-vided to evaluate the performance of the self-recovery watermarking schemes for image authentication.HE HongJie ZHANG JiaShu CHEN Fan 2008Science in China(Series F)2008,51,10:7
4The mixing of multi-source fluids in the Wusihe Zn–Pb ore deposit in Sichuan Province, Southwestern China显示文摘The Sichuan-Yunnan-Guizhou(SYG)metallogenic province of southwest China is one of the most important Zn-Pb ore zones in China,with^200 Mt ZnPb ores at mean grades of 10 wt.%Zn and 5 wt.%Pb.The source and mechanism of the regional Zn-Pb mineralization remain controversial despite many investigations that have been conducted.The Wusihe Zn-Pb deposit is a representative large-scale Zn-Pb deposit in the northern SYG,which mainly occurs in the Dengying Formation and yields Zn-Pb resources of^3.7 Mt.In this paper,Zn and S isotopes,and Fe and Cd contents of sphalerite from the Wusihe deposit were investigated in an attempt to constrain the controls on Zn and S isotopic variations,the potential sources of ore-forming components,and the possible mineralization mechanisms.Both theδ66Zn andδ34S values in sphalerite from the Wusihe deposit increase systematically from the bottom to the top of the strata-bound orebodies.Such spatial evolution inδ66Zn andδ34S values of sphalerite can be attributed to isotopic Rayleigh fractionation during sphalerite precipitation with temperature variations.The strong correlations between the Zn-S isotopic compositions and Fe-Cd concentrations in sphalerite suggest that their variations were dominated by a similar mechanism.However,the Rayleigh fractionation mechanism cannot explain the spatial variations of Fe and Cd concentrations of sphalerite in this deposit.It is noted that the bottom and top sphalerites from the strata-bound orebodies document contrasting Zn and S isotopic compositions which correspond to the Zn and S isotopic characteristics of basement rocks and host rocks,respectively.Therefore,the mixing of two-source fluids with distinct Zn-S isotopic signatures was responsible for the spatial variations of Zn-S isotopic compositions of sphalerite from the Wusihe deposit.The fluids from basement rocks are characterized by relatively lighter Zn(~0.2‰)and S(~5‰)isotopic compositions while the fluids from host rocks are marked by relatively heavier Zn(~0.6‰)and S(~15‰)isotopic compositions.Hongjie Zhang Haifeng Fan Chaoyi Xiao Hanjie Wen Lin Ye Zhilong Huang Jiaxi Zhou Qingjun Guo 2019Acta Geochimica2019,38,5:6
5Porosity and Oxide Layer Dependence of Thermal Shock Behavior of Porous Silicon Nitride Ceramics显示文摘A water-quenching technique has been adopted to evaluate thermal shock fracture and fatigue behaviors of porous Si3N4 ceramics in an air atmosphere. The high-porosity Si3N4 ceramics exhibit a higher strength retention and a better resistance to thermal shock fatigue because of its role of the pores as crack arresters.A dense and coherent surface oxide layer leads to a significant benefit in residual strength during thermal fatigue, however, an increased fatigue number to 30 th cycle cannot cause a further influence although a thicker oxide layer presents, which is attributed to holes defect and disappearance of part intergranular phase.Xuefeng Lu Yin Wei Hongjie Wang Jiangbo Wen Jun Zhou Jinpeng Fan 2014Journal of Materials Science & Technology2014,30,12:5

7A Cloud Detection Scheme for the Chinese Carbon Dioxide Observation Satellite(TANSAT)显示文摘Cloud detection is an essential preprocessing step for retrieving carbon dioxide from satellite observations of reflected sunlight.During the pre-launch study of the Chinese Carbon Dioxide Observation Satellite(TANSAT),a cloud-screening scheme was presented for the Cloud and Aerosol Polarization Imager(CAPI),which only performs measurements in five channels located in the visible to near-infrared regions of the spectrum.The scheme for CAPI,based on previous cloudscreening algorithms,defines a method to regroup individual threshold tests for each pixel in a scene according to the derived clear confidence level.This scheme is proven to be more effective for sensors with few channels.The work relies upon the radiance data from the Visible and Infrared Radiometer(VIRR)onboard the Chinese Feng Yun-3A Polar-orbiting Meteorological Satellite(FY-3A),which uses four wavebands similar to that of CAPI and can serve as a proxy for its measurements.The scheme has been applied to a number of the VIRR scenes over four target areas(desert,snow,ocean,forest)for all seasons.To assess the screening results,comparisons against the cloud-screening product from MODIS are made.The evaluation suggests that the proposed scheme inherits the advantages of schemes described in previous publications and shows improved cloud-screening results.A seasonal analysis reveals that this scheme provides better performance during warmer seasons,except for observations over oceans,where results are much better in colder seasons.Xi WANG Zheng GUO Yipeng HUANG Hongjie FAN Wanbiao LI 2017Advances in Atmospheric Sciences2017,34,1:4
8Solid ion transition route to 3D S-N-codoped hollow carbon nanosphere/graphene aerogel as a metal-free handheld nanocatalyst for organic reactions显示文摘新奇没有金属的体积 nanocatalyst, S-N-codoped 空碳 nanosphere/graphene aerogel (SNC-GA-1000 ) ,成功地用一条灵巧、干净的稳固的离子转变线路被制作了。在这个方法, ZnS 被用作难模板和 S 来源,当 polydopamine 充当一个减少的代理人和碳来源时。在高退火温度, Zn 金属被减少并且蒸发,离开仅仅自由的 S 蒸汽扩散进碳层。有趣地,同样获得的 SNC-GA-1000 比卸掉的赤裸的 S-N-codoped 碳 nanospheres 在器官的减小反应展出许多更高催化的活动。与 ZnS@polydopamine 核心壳 nanospheres (ZnS@PDA ) 装载的 graphene 氧化物表的热水的减小负担得起三维的体积 graphene aerogel。尽管 nanosized 催化剂展出高催化的活动,他们的随后的分离不总是是令人满意的,成为处理以后困难。这条途径完成在活动和可分性之间的一宗交易。更重要地,由于 3D,结构的自然,如此的体积和手持 nanocatalysts 能容易被分开并且再循环。Jing Pan Shuyan Song Junqi Li Fan Wang Xin Ge Shuang Yao Xiao Wang Hongjie Zhang 2017Nano Research2017,10,10:3
9Analysis of electromagnetic propagation in birefringent thin film显示文摘In general, the propagating behavior of extraordinary wave in anisotropic materials is different from that in isotropic materials. With the tangential continuity of Maxwell’s equations, the electromagnetic propagating behaviors have been investigated at the incident and exit interfaces of the uniaxial anisotropic thin film. The emphasis was placed on two interesting optical phenomena such as homolateral refraction behavior and wide-angle Brewster’s phenomenon, which occurred at the interfaces of uniaxial anisotropic thin film.QI Hongji WANG Jianguo SHAO Jianda FAN Zhengxiu 2005Science China(Physics,Mechanics & Astronomy)2005,48,5:3
10Rare-earth based materials:an effective toolbox for brain imaging,therapy,monitoring and neuromodulation显示文摘Brain diseases, including tumors and neurodegenerative disorders, are among the most serious health problems. Non-invasively high-resolution imaging methods are required to gain anatomical structures and information of the brain. In addition, efficient diagnosis technology is also needed to treat brain disease. Rare-earth based materials possess unique optical properties, superior magnetism, and high X-ray absorption abilities, enabling high-resolution imaging of the brain through magnetic resonance imaging, computed tomography imaging, and fluorescence imaging technologies. In addition, rare-earth based materials can be used to detect, treat, and regulate of brain diseases through fine modulation of their structures and functions. Importantly, rare-earth based materials coupled with biomolecules such as antibodies, peptides, and drugs can overcome the blood-brain barrier and be used for targeted treatment. Herein, this review highlights the rational design and application of rare-earth based materials in brain imaging, therapy, monitoring, and neuromodulation. Furthermore, the development prospect of rare-earth based materials is briefly introduced.Zheng Wei Yawei Liu Bo Li Jingjing Li Shuang Lu Xiwen Xing Kai Liu Fan Wang Hongjie Zhang 2022Light(Science & Applications)2022,11,8:3
11Probabilistic total transfer capability analysis based on static voltage stability region integrated with a modified distributed-level nodal-loading model显示文摘In this paper, a new evaluation method of probabilistic TTC based on SVSR calculation is developed through a hierarchical simulation. A smooth technology based on the non-parametric kernel estimator is adapted to obtain the time-dependent probabilistic density function of the feeder-head load data. In order to describe possible operating change directions of the operating point, the original hyper-cone-like(HCL) model is constructed to consider the probabilistic distribution function(PDF) extracted from feeder-head load data to replace the simple Normal Distribution model and the uncertain generator outputs. To realize the fast TTC calculation of the current operating point in random conditions, a sub-hyper-cone-like(SHCL) model in full power injections space is proposed, which is a similarity transformation of the original one.WANG Dan ZHOU Yue JIA HongJie WANG ChengShan LU Ning FAN MengHua 2015Science China(Technological Sciences)2015,58,12:2
12Biological composite fibers with extraordinary mechanical strength and toughness mediated by multiple intermolecular interacting networks显示文摘Numerous strategies involving multiple cross-linking networks have been applied for fabricating robust hydrogels.Inspired by this,the development of mechanically strong and tough biological fibers by the incorporation of intermolecular linking networks is becoming important.Herein,we present a versatile strategy for the fabrication of protein-saccharide composite fibers through protein-initiated double interacting networks.Three types of lysine-rich bioengineered proteins were introduced and the present multiple cross-linking interactions including electrostatic forces and covalent bonds significantly enhanced the mechanical properties of as-obtained composite fibers.In stark contrast to pristine saccharide or other polymer fibers,the as-obtained composite fibers exhibited outstanding mechanical performance,showing a breaking strength of~768 MPa,Young’s modulus of~24 GPa,and toughness of~69 MJ∙m^(–3),respectively.Thus,this established approach has great potentials to fabricate new generation renewable biological fibers with high performance.Sikang Wan Wenhao Cheng Jingjing Li Fan Wang Xiwen Xing Jing Sun Hongjie Zhang Kai Liu 2022Nano Research2022,15,10:2
13Enhanced Answer Selection in CQA Using Multi-Dimensional Features Combination显示文摘Community Question Answering(CQA) in web forums, as a classic forum for user communication,provides a large number of high-quality useful answers in comparison with traditional question answering.Development of methods to get good, honest answers according to user questions is a challenging task in natural language processing. Many answers are not associated with the actual problem or shift the subjects,and this usually occurs in relatively long answers. In this paper, we enhance answer selection in CQA using multidimensional feature combination and similarity order. We make full use of the information in answers to questions to determine the similarity between questions and answers, and use the text-based description of the answer to determine whether it is a reasonable one. Our work includes two subtasks:(a) classifying answers as good, bad, or potentially associated with a question, and(b) answering YES/NO based on a list of all answers to a question. The experimental results show that our approach is significantly more efficient than the baseline model, and its overall ranking is relatively high in comparison with that of other models.Hongjie Fan Zhiyi Ma Hongqiang Li Dongsheng Wang Junfei Liu 2019Tsinghua Science and Technology2019,24,3:2

15Birefringent non-polarizing thin film design显示文摘In this paper, 2×2 characteristic matrices of uniaxially anisotropic thin film for extraordinary and ordinary wave are deduced at oblique incidence. Furthermore, the reflectance and transmittance of thin films are calculated separately for two polarizations, which provide a new concept for designing non-polarizing thin films at oblique incidence. Besides, using the multilayer birefringent thin films, non-polarizing designs, such as beam splitter thin film at single wavelength, edge filter and antireflection thin film over visible spectral region are obtained at oblique incidence.QI Hongji HONG Ruijin HE Hongbo SHAO Jianda FAN Zhengxiu 2005Science China(Technological Sciences)2005,48,1:2
16Ultra-early treatment of bone marrow-derived mesenchymal stem cells for focal cerebral ischemia/ reperfusion injury显示文摘The time point at which bone marrow-derived mesenchymal stem cells (BMSCs) can be used in transplantation for the treatment of ischemic brain injury remains unclear. In the present study, BMSCs were transplanted to the ischemic site 90 minutes post-ischemia. The results demonstrated that the transplanted BMSCs improved neurological function, reduced infarct volume, increased survivin expression, decreased caspase-3 expression and reduced apoptosis. This suggests that BMSCs transplanted at an ultra-early stage ameliorated brain ischemia by increasing survivin expression, decreasing caspase-3 expression and reducing apoptosis at the ischemia/reperfusion injury site.Hongjie Fan Weidong Yu Zongli Wang Qian Wang Zhiyi He 2010Neural Regeneration Research2010,5,17:2
17Proteinaceous Fibers with Outstanding Mechanical Properties Manipulated by Supramolecular Interactions显示文摘Proteinaceous fibers based on spidroins have attracted widespread attention due to their lightweight and mechanically strong properties.Presently,mechanical modulation is mainly dependent on the ultrahigh molecular weight of recombinant proteins.This makes it difficult to construct and express the target proteins.It is thus significant to develop alternative strategies for the fabrication of robust biological fibers.Herein,we demonstrate one new type of engineered protein fibers using electrostatic complexation of the cationic elastins and anionic dihydroxyphenylalanine surfactants.Interestingly,the mechanical performance of the resulting fibers can be modulated by multiple supramolecular interactions in the system including electrostatic force,hydrogen bonding,metal coordination,cation-πand other aromatic interactions.Consequently,significant alternation of the fibers’breaking strength(from 32 to 160 MPa),Young’s modulus(from 0.8 to 17 GPa),and toughness(from 1.2 to 99 MJ·m-3)has been achieved.Moreover,the fibers exhibit high plasticity;for example,the formation of different helical structures,and strong fluorescence after the introduction of Tb chelation.Therefore,this study offers new strategies for the mechanical regulation of engineered protein fibers.Jing Sun Bo Li Fan Wang Jing Feng Chao Ma Kai Liu Hongjie Zhang 2021CCS Chemistry2021,3,6:2
