| 1 | Hydrochlorination of Acetylene Using SiC Foam Supported Structured C/Au Catalysts显示文摘AUCI_3 loaded structured catalysts were prepared on SiC foam supported with pre-coated activated carbon layers.The catalytic properties of the structured catalysts towards hydrochlorination of acetylene were tested in a fixedbed reactor with the AuCI_3 loaded on activated carbon pellets as a reference.For isopyknic catalysts,the structured catalyst with only one fifth of the Au amount as that was used on the reference catalyst exhibited even a little higher acetylene conversion and much better stability than the latter no matter what the gas hourly space velocities of acetylene were used.The results indicated that the more homogeneous distribution of AUCI_3 particles and better heat transfer along the fixed-bed reactor originated from the low pressure drop and high thermal conductivity of the SiC foam supported structured catalysts might be able to account for their improved efficiency and stability.It is believed that these novel structured C/Au catalysts can be potentially applied in VCM industrialization in view of their greatly reduced cost and much prolonged life. | Xiaodan Yang Chunhai Jiang Zhenming Yang Jinsong Zhang | 2014 | Journal of Materials Science & Technology2014，30，5： | 6 |
| 2 | Nitrogen-doped amorphous carbon coated mesocarbon microbeads as excellent high rate Li storage anode materials显示文摘A composite anode material consisting of a stable inner core of mesocarbon microbeads and a porous nitrogen-doped amorphous carbon shell active for lithium storage is prepared. The thin birnessite MnO_2 nanosheets hydrothermally deposited on mesocarbon microbeads are in situ replaced by polypyrrole,which is then transformed to nitrogen-doped amorphous carbon layer by calcination in nitrogen atmosphere. The surface modified mesocarbon microbeads exhibit average discharge capacities of 444 and103 m A h g^(-1) at the current densities of 0.1 and 3 A g^(-1) , respectively, obvious higher than the corresponding values of the bare sample, 371 and 60 mA h g^(-1) . Moreover, the composite anode maintains a discharge capacity of 306 mA h g^(-1) after 500 cycles at 1 A g^(-1) , suggesting an excellent cycle stability. It is believed that the nitrogen-doped amorphous carbon layer has provided additional lithium storage capacity and stabilized the structure integrity of mesocarbon microbeads. This work demonstrates that the capacity and rate performance of commercial graphitic carbons can be much improved by simply introducing a nitrogen-doped carbon coating layer active for Li storage, making them attractive for high power Li-ion batteries. | Zhimin Zou Chunhai Jiang | 2019 | Journal of Materials Science & Technology2019，35，4： | 3 |
| 3 | Superresolution imaging of telomeres with continuous wave stimulated emission depletion (STED) microscope显示文摘The significant role of telomeres in cells has attracted much attention since they were discovered.Fluorescence imaging is an effective method to study subcellular structures like telomeres.However,the diffraction limit of traditional optical microscope hampers further investigation on them.Recent progress on superresolution fluorescence microscopy has broken this limit.In this work,we used stimulated emission depletion(STED) microscope to observe fluorescence-labeled telomeres in interphase cell nuclei.The results showed that the size of fluorescent puncta representing telomeres under the STED microscope was much smaller than that under the confocal microscope.Two adjacent telomeres were clearly separated via STED imaging,which could hardly be discriminated by confocal microscopy due to the diffraction limit.We conclude that STED microscope is a more powerful tool that enable us to obtain detailed information about telomeres. | Shaopeng Wang Suhui Deng Xiaoqing Cai Shangguo Hou Jiajun Li Zhaoshuai Gao Jiang Li Lihua Wang Chunhai Fan | 2016 | Science China Chemistry2016，59，11： | 3 |
| 4 | Genetically encoded X-ray cellular imaging for nanoscale protein localization显示文摘Spatial resolution defines the physical limit of microscopes for probing biomolecular localization and interactions in cells.Whereas synchrotron-based X-ray microscopy(XRM)represents a unique approach for imaging a whole cell with nanoscale resolution due to its intrinsic nanoscale resolution and great penetration ability,existing approaches to label biomolecules rely on the use of exogenous tags that are multi-step and error-prone.Here,we repurpose engineered peroxidases as genetically encoded X-ray-sensitive tags(GXET)for site-specific labeling of protein-of-interest in mammalian cells.We find that 3,3-diaminobenzidine(DAB)polymers that are in-situ catalytically formed by fusion-expressed peroxidases are visible under XRM.Using this new tag,we imaged the protein location associated with the alteration of a DNA-methylation pathway with an ultra-high resolution of 30 nanometers.Importantly,the excellent energy resolution of XRM enables multicolor imaging using different peroxidase tags.The development of GXET enlightens the way to nanoscopic imaging for biological studies. | Huating Kong Jichao Zhang Jiang Li Jian Wang Hyun-Joon Shin Renzhong Tai Qinglong Yan Kai Xia Jun Hu Lihua Wang Ying Zhu Chunhai Fan | 2020 | National Science Review2020，7，7： | 3 |
| 5 | Robust and efficient direct multiplex amplification method for large-scale DNA detection of blood samples on FTA cards显示文摘Deoxyribonucleic acid (DNA) damage arising from radiations widely occurred along with the development of nuclear weapons and clinically wide application of computed tomography (CT) scan and nuclear medicine. All ionizing radiations (X-rays, γ-rays, alpha particles, etc.) and ultraviolet (UV) radiation lead to the DNA damage. Polymerase chain reaction (PCR) is one of the most wildly used techniques for detecting DNA damage as the amplification stops at the site of the damage. Improvements to enhance the efficiency of PCR are always required and remain a great challenge. Here we establish a multiplex PCR assay system (MPAS) that is served as a robust and efficient method for direct detection of target DNA sequences in genomic DNA. The establishment of the system is performed by adding a combination of PCR enhancers to standard PCR buffer. The performance of MPAS was demonstrated by carrying out the direct PCR amplification on 1.2 mm human blood punch using commercially available primer sets which include multiple primer pairs. The optimized PCR system resulted in high quality genotyping results without any inhibitory effect indicated and led to a full-profile success rate of 98.13%. Our studies demonstrate that the MPAS provides an efficient and robust method for obtaining sensitive, reliable and reproducible PCR results from human blood samples. | JIANG Bowei XIANG Fawei ZHAO Xingchun WANG Lihua FAN Chunhai | 2013 | Nuclear Science and Techniques2013，24，3： | 3 |
| 6 | A Nano-and Micro-Integrated Protein Chip Based on Quantum Dot Probes and a Microfluidic Network显示文摘A novel nano-and micro-integrated protein chip(NMIPC)that can detect proteins with ultrahigh sensitivity has been fabricated.A microfl uidic network(μFN)was used to construct the protein chips,which allowed facile patterning of proteins and subsequent biomolecular recognition.Aqueous phase-synthesized,water-soluble fl uorescent CdTe/CdS core-shell quantum dots(aqQDs),having high quantum yield and high photostability,were used as the signaling probe.Importantly,it was found that aqQDs were compatible with microfluidic format assays,which afforded highly sensitive protein chips for cancer biomarker assays. | Juan Yan Mei Hu Di Li Yao He Rui Zhao Xingyu Jiang Shiping Song Lianhui Wang Chunhai Fan | 2008 | Nano Research2008，1，6： | 3 |
| 7 | Copolymerization-Assisted Preparation of Porous LiMn_2O_4 Hollow Microspheres as High Power Cathode of Lithium-ion Batteries显示文摘Porous LiMn2O4 hollow microspheres were facilely prepared by incorporation of Li and Mn elements into a spherical polymeric precursor through copolymerization of lithium and manganese acetates with resorcinol and hexamethylenetetramine and then burning off the organic matrix at appropriate temperatures in air. The LiMn_2O_4 inherited the spherical morphology of the polymeric precursor but showed hollow porous structure assembled by nanocrystals of about 50–100 nm in size. When tested as cathode of Li-ion batteries, the LiMn_2O_4 hollow spheres exhibited excellent rate capability and cycle stability.A discharge capacity of above 90 mAhg^(-1)was maintained at 10 C(1C = 120 mAg^(-1)), and the cells can still deliver a discharge capacity over 100 mAhg^(-1)after another 115 cycles at 0.5 C. With such excellent electrochemical properties, the prepared LiMn_2O_4 hollow microspheres could be promising cathode of Li-ion batteries for long term and high power applications. | Zhimin Zou Zhaojin Li Hui Zhang Xiaohui Wang Chunhai Jiang | 2017 | Journal of Materials Science & Technology2017，33，8： | 2 |
| 8 | Sub-diffraction-limit cell imaging using a super-resolution microscope with simplified pulse synchronization显示文摘Stimulated emission depletion(STED) microscope is one of the most prominent super-resolution bio-imaging instruments, which holds great promise for ultrahigh-resolution imaging of cells. To construct a STED microscope, it is challenging to realize temporal synchronization between the excitation pulses and the depletion pulses. In this study, we present a simple and low-cost method to achieve pulse synchronization by using a condensed fluorescent dye as a depletion indicator. By using this method, almost all the confocal microscopes can be upgraded to a STED system without losing its original functions. After the pulse synchronization,our STED system achieved sub-100-nm resolution for fluorescent nanospheres and single-cell imaging. | Zhaoshuai Gao Suhui Deng Jiang Li Kun Wang Jiajun Li Lihua Wang Chunhai Fan | 2017 | Science China Chemistry2017，60，10： | 2 |

| 12 | Nanoengineering Titania for High Rate Lithium Storage: A Review显示文摘Nanostructured titania have been intensively investigated as anode materials of Li-ion batteries for their excellent high rate performance. The size effects of TiO2 polymorphs (mainly rutile, anatase and TiO2-B) on their electrochemical performance and the latest efforts in nanoengineering titania anodes through enhancing their ionic or electronic transportation or both are reviewed in this work. We suppose that micron- or submicronsized porous structures assembled by TiO2 nanoparticles, nanowires/nanotubes or nanosheets with a high percentage of exposing high reactive facets together with a conductive percolating network are ideal anodes not only for high rate lithium storage but also for high packing densities of the active materials. | Chunhai Jiang Jinsong Zhang | 2013 | Journal of Materials Science & Technology2013，29，2： | 1 |

| 14 | Functional DNA Structures and Their Biomedical Applications显示文摘Since the discovery of the double-helix structure in 1953,nucleic acids have been developed from natural genetic codes into functional building blocks in a wide range of biotechnology and materials sciences.Taking advantage of their design diversity and biocompatibility,functional nucleic acids facilitate the“bottom-up”fabrication of nanomaterials that are highly potential for molecular medicine to treat different diseases,such as cancers.The present perspective article introduces recent advances in the use of these unique properties of nucleic acid biopolymers for biomedical applications.Specifically,nanomaterial/nucleic acid hybrid structures for sensing,controlled drug release,programmable intracellular imaging,and apoptosis,as well as logic calculation,are discussed.Furthermore,the detailed operation for both extracellular and intracellular bioactivity regulation with these new design functional nucleic acid nanostructures are fully illustrated. | Ziyuan Li Chen Wang Jiang Li Junji Zhang Chunhai Fan Itamar Willner He Tian | 2020 | CCS Chemistry2020，2，5： | 1 |

| 16 | Phase transferring luminescent gold nanoclusters via single-stranded DNA显示文摘Atomically precise gold nanoclusters(Au NCs) are an emerging class of quantum-sized nanomaterials with discrete electronic energy levels, which has led to a range of attractive electronic and optical applications. Nevertheless, the lack of general methods to transfer Au NCs protected with hydrophobic ligands to an aqueous solution hampers their use in physiological settings. Here,we developed a single-stranded DNA-based approach that could transfer ~90% hydrophobic Au NCs into an aqueous solution.We experimentally and theoretically established that multivalent electrostatic and hydrophobic interactions between DNA strands and the hydrophobic ligand layer on Au NCs resulted in monodispersed DNA-coated Au NCs with high physical integrity in an aqueous solution. The fluorescence quantum yield of Au NCs was increased by ~13 fold, and surface-constrained DNA retained the specific recognition ability for biosensing. We further demonstrated the versatility of this phase-transfer approach, which thus holds great potential to advance biological and medical applications of Au NCs. | Yu Li Hui Lu Zhibei Qu Mingqiang Li Haoran Zheng Peilin Gu Jiye Shi Jiang Li Qian Li Lihua Wang Jing Chen Chunhai Fan Jianlei Shen | 2022 | Science China Chemistry2022，65，6： | 1 |

| 19 | Novel TiC/Ti Open Cellular Foams Prepared by a Modified Sponge-coating Method Using High Frequency Induction Heating Process显示文摘A new kind of open cellular foam material with three dimensionally interconnected TiC/Ti struts was prepared by a two-step sponge-coating and high frequency induction heating process.The microstructure,composition and compression strength of the prepared TiC/Ti foam materials were characterized.It was confirmed that the incorporation of Ti into TiC resulted in an inter-bonded Ti-TiC-Ti layered structure in the struts,which enhanced the plasticity of the composite foam materials. | Yong Gao Xingxiang Xu Zhenming Yang Junqi Zhang Chunhai Jiang Jinsong Zhang | 2013 | Journal of Materials Science & Technology2013，29，4： | 1 |
| 20 | Photocatalytic Activities of TiO_2 Coated on Different Semiconductive SiC Foam Supports显示文摘Different semiconductive SiC foam supports were prepared by varying the sintering temperature and atmosphere,and with or without alkaline solution treatment and high temperature oxidation following a macromolecule pyrogenation combined with reaction bonding method.Nano-TiO_2 particles were immobilized onto these SiC foam supports by a composite sol—gel method.The phase,surface morphology,the type of conduction and the photocatalytic activity of the TiO_2—SiC composite photocatalysts were studied.The TiO_2coated on p-type Si-free SiC support showed the highest photocatalytic efficiency in degradation of 4-aminobenzenesulfonic acid(4-ABS) in aqueous solution as compared to that coated on n-type SiC support and p-type SiC supports with residual Si or SiO_2 on the surface.The result showed that the TiO_2 coatings immobilized on p-type semiconductive SiC foam supports exhibited obviously higher photocatalytic activity in comparison to that coated on n-type SiC foam support.The p—n heterojunctions formed between the p-type SiC supports and n-type TiO_2 coatings might be able to account for the better charge separation and transfer as well as the photocatalytic activity of the TiO_2—SiC composite photocatalyst. | Dong Hao Zhenming Yang Chunhai Jiang Jinsong Zhang | 2013 | Journal of Materials Science & Technology2013，29，11： | 1 |
