| 1 | Ultrafast epitaxial growth of metre-sized single-crystal graphene on industrial Cu foil显示文摘A foundation of the modern technology that uses single-crystal silicon has been the growth of highquality single-crystal Si ingots with diameters up to 12 inches or larger. For many applications of graphene, large-area high-quality(ideally of single-crystal) material will be enabling. Since the first growth on copper foil a decade ago, inch-sized single-crystal graphene has been achieved. We present here the growth, in 20 min, of a graphene film of(5 ×50) cm^2 dimension with >99% ultra-highly oriented grains.This growth was achieved by:(1) synthesis of metre-sized single-crystal Cu(1 1 1) foil as substrate;(2)epitaxial growth of graphene islands on the Cu(1 1 1) surface;(3) seamless merging of such graphene islands into a graphene film with high single crystallinity and(4) the ultrafast growth of graphene film.These achievements were realized by a temperature-gradient-driven annealing technique to produce single-crystal Cu(1 1 1) from industrial polycrystalline Cu foil and the marvellous effects of a continuous oxygen supply from an adjacent oxide. The as-synthesized graphene film, with very few misoriented grains(if any), has a mobility up to ~23,000 cm^2 V^(-1)s^(-1)at 4 K and room temperature sheet resistance of ~230 Ω/□. It is very likely that this approach can be scaled up to achieve exceptionally large and high-quality graphene films with single crystallinity, and thus realize various industrial-level applications at a low cost. | Xiaozhi Xu Zhihong Zhang Jichen Dong Ding Yi Jingjing Niu Muhong Wu Li Lin Rongkang Yin Mingqiang Li Jingyuan Zhou Shaoxin Wang Junliang Sun Xiaojie Duan Peng Gao Ying Jiang Xiaosong Wu Hailin Peng Rodney S.

| 2 | Seasonal variation of potential denitrification rates of surface sediment from Meiliang Bay, Taihu Lake, China显示文摘The regulatory effects of environmental factors on denitrification were studied in the sediments of Meiliang Bay, Taihu Lake, in a monthly sampling campaign over a one-year period. Denitrification rates were measured in slurries of field samples and enrichment experiments using the acetylene inhibition technique. Sediment denitrification rates in inner bay and outer bay ranged from 2.8 to 51.5 nmol N2/(g dw (dry weight)·hr) and from 1.5 to 81.1 nmol N2/(g dw·hr), respectively. Sediment denitrification rates were greatest in the spring and lowest in the summer and early autumn, due primarily to seasonal differences in nitrate concentration and water temperature. For each site, positive and linear relationships were regularly observed between denitrification rate and water columnn itrate concentration. Of various environmental factors on denitrification that we assessed, nitrate was determined to be the key factor limiting denitrification rates in the sediments of Meiliang Bay. In addition, at the two sites denitrification rates were also regulated by temperature. The addition of organic substrates had no significant effect on denitrification rate, indicating that sediment denitrification was not limited by organic carbon availability in the sediments. Nitrate in the water column was depleted during summer and early autumn, and this suppressed effective removal of nitrogen from Taihu Lake by denitrification. | Jicheng Zhong, Chengxin Fan, Guofeng Liu, Lei Zhang, Jingge Shang, Xiaozhi GuState Key Laboratory of Lake Science and Environment, Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Nanjing 210008, China. | 2010 | Journal of Environmental Sciences2010,22,7: | 29 |
| 3 | Impact of different benthic animals on phosphorus dynamics across the sediment-water interface显示文摘As a diagenetic progress, bioturbation influences solute exchange across the sediment-water interface (SWI). Different benthic animals have various mechanical activities in sediment, thereby they may have different effects on solute exchange across the SWI. This laboratory study examined the impacts of different benthic animals on phosphorus dynamics across the SWI. Tubificid worms and Chironomidae larvae were introduced as model organisms which, based on their mechanical activities, belong to upward-conveyors and gallery-diffusers, respectively. The microcosm simulation study was carried out with a continuous flow culture system, and all sediment, water, and worms and larvae specimens were sampled from Taihu Lake, China. To compare their bioturbation effects, the same biomass (17.1 g wet weight (ww)/m 2 ) was adopted for worms and larvae. Worms altered no oxygen penetration depth in sediment, while larvae increased the O 2 penetration depth, compared to the control treatment. Their emergence also enhanced sediment O 2 uptake. The oxidation of ferrous iron in pore water produced ferric iron oxyhydroxides that adsorbed soluble reactive phosphorus (SRP) from the overlying water and pore water. Larvae built obviously oxidized tubes with about 2 mm diameter and the maximum length of 6 cm in sediment, and significantly decreased ferrous iron and SRP in the pore water compared to the control and worms treatments. Worms constructed no visually-oxidized galleries in the sediment in contrast to larvae, and they did not significantly alter SRP in the pore water relative to the control treatment. The adsorption of ferric iron oxyhydroxides to SRP caused by worms and larvae inhibited SRP release from sediment. Comparatively, worms inhibited more SRP release than larvae based on the same biomass, as they successively renewed the ferric iron oxyhydroxides rich oxidation layer through their deposition. | Lei Zhang Xiaozhi Gu Chengxin Fan Jingge Shang Qiushi Shen Zhaode Wang Ji Shen | 2010 | Journal of Environmental Sciences2010,22,11: | 14 |
| 4 | Brain-derived neurotrophic factor induces neuron-like cellular differentiation of mesenchymal stem cells derived from human umbilical cord blood cells in vitro显示文摘Human umbilical cord blood was collected from full-term deliveries scheduled for cesarean section.Mononuclear cells were isolated,amplified and induced as mesenchymal stem cells.Isolated mesenchymal stem cells tested positive for the marker CD29,CD44 and CD105 and negative for typical hematopoietic and endothelial markers.Following treatment with neural induction medium containing brain-derived neurotrophic factor for 7 days,the adherent cells exhibited neuron-like cellular morphology.Immunohistochemical staining and reverse transcription-PCR revealed that the induced mesenchymal stem cells expressed the markers for neuron-specific enolase and neurofilament.The results demonstrated that human umbilical cord blood-derived mesenchymal stem cells can differentiate into neuron-like cells induced by brain-derived neurotrophic factor in vitro. | Lei Chen Zhongguo Zhang Bing Chen Xiaozhi Liu Zhenlin Liu Hongliang Liu Gang Li Zhiguo Su Junfei Wang Guozhen Hui | 2011 | Neural Regeneration Research2011,6,13: | 8 |
| 5 | Band structure engineering in metal halide perovskite nanostructures for optoelectronic applications显示文摘Metal halide perovskite nanostructures have emerged as low-dimensional semiconductors of great significance in many fields such as photovoltaics,photonics,and optoelectronics.Extensive efforts on the controlled synthesis of perovskite nanostructures have been made towards potential device applications.The engineering of their band structures holds great promise in the rational tuning of the electronic and optical properties of perovskite nanostructures,which is one of the keys to achieving efficient and multifunctional optoelectronic devices.In this article,we summarize recent advances in band structure engineering of perovskite nanostructures.A survey of bandgap engineering of nanostructured perovskites is firstly presented from the aspects of dimensionality tailoring,compositional substitution,phase segregation and transition,as well as strain and pressure stimuli.The strategies of electronic doping are then reviewed,including defect-induced self-doping,inorganic or organic molecules-based chemical doping,and modification by metal ions or nanostructures.Based on the bandgap engineering and electronic doping,discussions on engineering energy band alignments in perovskite nanostructures are provided for building high-performance perovskite p-n junctions and heterostructures.At last,we provide our perspectives in engineering band structures of perovskite nanostructures towards future low-energy optoelectronics technologies. | Qingdong Ou Xiaozhi Bao Yinan Zhang Huaiyu Shao Guichuan Xing Xiangping Li Liyang Shao Qiaoliang Bao | 2019 | Nano Materials Science2019,1,4: | 5 |
| 6 | Scalable and ultrafast epitaxial growth of single-crystal graphene wafers for electrically tunable liquid-crystal microlens arrays显示文摘The scalable growth of wafer-sized single-crystal graphene in an energy-efficient manner and compatible with wafer process is critical for the killer applications of graphene in high-performance electronics and optoelectronics. Here, ultrafast epitaxial growth of single-crystal graphene wafers is realized on singlecrystal Cu90Ni10(1 1 1) thin films fabricated by a tailored two-step magnetron sputtering and recrystallization process. The minor nickel(Ni) content greatly enhances the catalytic activity of Cu, rendering the growth of a 4 in. single-crystal monolayer graphene wafer in 10 min on Cu90Ni10(1 1 1), 50 folds faster than graphene growth on Cu(1 1 1). Through the carbon isotope labeling experiments, graphene growth on Cu90Ni10(1 1 1) is proved to be exclusively surface-reaction dominated, which is ascribed to the Cu surface enrichment in the Cu Ni alloy, as indicated by element in-depth profile. One of the best benefits of our protocol is the compatibility with wafer process and excellent scalability. A pilot-scale chemical vapor deposition(CVD) system is designed and built for the mass production of single-crystal graphene wafers, with productivity of 25 pieces in one process cycle. Furthermore, we demonstrate the application of single-crystal graphene in electrically controlled liquid-crystal microlens arrays(LCMLA), which exhibit highly tunable focal lengths near 2 mm under small driving voltages. By integration of the graphene based LCMLA and a CMOS sensor, a prototype camera is proposed that is available for simultaneous light-field and light intensity imaging. The single-crystal graphene wafers could hold great promising for highperformance electronics and optoelectronics that are compatible with wafer process. | Bing Deng Zhaowei Xin Ruiwen Xue Shishu Zhang Xiaozhi Xu Jing Gao Jilin Tang Yue Qi Yani Wang Yan Zhao Luzhao Sun Huihui Wang Kaihui Liu Mark H.

| 7 | Porous Pt nanoframes decorated with Bi(OH)3 as highly efficient and stable electrocatalyst for ethanol oxidation reaction显示文摘High-quality Pt-based catalysts are highly desirable for ethanol oxidation reaction(EOR),which is of critical importance for the commercial applications of direct ethanol fuel cells(DEFCs).However,most of the Pt-based catalysts have suffered from high cost and low operation durability.Herein a two-step method has been developed to synthesize porous Pt nanoframes decorated with Bi(OH)3,which show excellent catalytic activity and operation durability in both alkaline and acidic media.For example,the nanoframes show a mass activity of 6.87 A·mgPt−1 in alkaline media,which is 13.5-fold higher than that of commercial Pt/C.More importantly,the catalyst can be reactivated simply,which shows negligible activity loss after running for 180,000 s.Further in situ attenuated total reflection-infrared(ATR-IR)absorption spectroscopy and CO-stripping experiments indicate that surface Bi(OH)3 species can greatly facilitate the formation of adsorbed OH species and subsequently remove carbonaceous poison,resulting in a significantly enhanced stability towards EOR.This work may favor the tailoring of desired electrocatalysts with high activity and durability for future commercial application of DEFCs. | Xiaolei Yuan Bei Jiang Muhan Cao Congyang Zhang Xiaozhi Liu Qinghua Zhang Fenglei Lyu Lin Gu Qiao Zhang | 2020 | Nano Research2020,13,1: | 3 |

| 9 | AEG-1 expression correlates with CD133 and PPP6c levels in human glioma tissues显示文摘Astrocyte elevated gene-1(AEG-1) is associated with tumor genesis and progression in a variety of human cancers.This study aimed to explore the significance of AEG-l in glioma and investigate whether it correlated with radioresistance of glioma cells.Immunohistochemical staining showed that the intensity of AEG-l,CD133 and PPP6 c protein expression in glioma tissues increased significantly,mainly in the cytoplasm.The expression rate of AEG-l,CD133 and PPP6c were 85.9%(67/78),60.3%(47/78) and 65.8%(51/78),respectively.AEG-l expression was correlated with age(r=0.227,P=0.045),clinical stage(r=0.491,P<0.001) and clinical grade(r=0.450,P<0.001).No correlation was found between AEG-l expression and other clinicopathologic parameters(P>0.05).The expression of AEG-1 was positively correlated with the expression of CD133(r=0.240,P = 0.035) and PPP6c(r= 0.250,P = 0.027).In addition,retrieved data on TCGA implied co-occurrence of genomic alterations of AEG-l and PPP6 c in glioblastoma.Our findings indicate that AEG-l is positively correlated with CD133 and AEG-l expression.It may play an important role in the progression of glioma and may serve as potential novel marker of chemoresistance and radioresistance. | Jia Guo Xin Chen Ruxing Xi Yuwei Chang Xuanwei Zhang Xiaozhi Zhang | 2014 | The Journal of Biomedical Research2014,28,5: | 3 |
| 10 | Optimizing the grain size and grain boundary morphology of (K,Na) NbO_(3)-based ceramics: Paving the way for ultrahigh energy storage capacitors显示文摘Relaxor dielectric ceramic capacitors are very attractive for high-power energy storage.However,the low breakdown strength severely restricts improvements to the energy storage density and practical application.Here,a strategy of designing small grain sizes and abundant amorphous grain boundaries is proposed to improve the energy storage properties under the guidance of phase field theory.0.925(K_(0.5)Na_(0.5))NbO_(3)-e0.075Bi(Zn_(2/3)(Ta_(0.5)Nb_(0.5))1/3)O_(3)(KNNe-BZTN)relaxor ferroelectric ceramic is taken as an example to verify our strategy.The grain sizes and grain boundaries of the KNNeBZTN ceramics are carefully controlled by the high-energy ball milling method and twoestep sintering strategy.Impedance analysis and diffusion reflectance spectra demonstrate that KNNeBZTN ceramics with a small grain size and abundant amorphous grain boundary exhibit a lower charge carrier concentration and higher band gap.As a consequence,the breakdown electric field of KNNeBZTN ceramics increases from 222 kV/cm to 317 kV/cm when the grain size is decreased from 410 nm to 200 nm,accompanied by a slightly degraded maximum polarization.KNNeBZTN ceramics with an average grain size of~250 nm and abundant amorphous grain boundaries exhibit optimum energy storage properties with a high recoverable energy density of 4.02 J/cm^(3) and a high energy efficiency of 87.4%.This successful local structural design opens up a new paradigm to improve the energy storage performance of other dielectric ceramic capacitors for electrical energy storage. | Xiaozhi Wang Yu Huan Peiyao Zhao Xiaoming Liu Tao Wei Qiwen Zhang Xiaohui Wang | 2021 | Journal of Materiomics2021,7,4: | 3 |

| 12 | Crystal phase-controlled growth of PtCu and PtCo alloys on 4H Au nanoribbons for electrocatalytic ethanol oxidation reaction显示文摘Crystal phase can greatly affect the physicochemical properties and applications of nanomaterials.However,it stil remains a great challenge to synthesize nanostructures with the same composition and morphology but different phases in order to explore the phase-dependent properties and applications.Herein,we report the crystal phase-controlled synthesis of PtCu alloy shells on 4H Au nanoribbons(NRBs),referred to as 4H-Au NRBs,to form the 4H-Au@PtCu core-shell NRBs.By tuning the thickness of PtCu,4H-PtCu and face-centered cubic(cc)phase PICu(cc-PtCu)alloy shells are successtully grown on the 4H-Au NRB cores.This thickness-dependent phase-controlled growth strategy can also be used to grow PtCo alloys with 4H or fcc phase on 4H-Au NRBs.Significantly,when used as electrocatalysts for the ethanol oxidation reaction(EOR)in alkaline media,the 4H-Au@4H-PtCu NRBs show much better EOR performance than the 4H-Au@fcc-PtCu NRBs,and both of them possess superior performance compared to the commercial Pt black.Our study provides a strategy on phase-contolled synthesis of nanomaterials used for crystal phase-dependent applications. | Jie Wang Jian Zhang Guigao Liu Chongyi Ling Bo Chen Jingtao Huang Xiaozhi Liu Bing Li An-Liang Wang Zhaoning Hu Ming Zhou Ye Chen Hongfei Cheng Jiawei Liu Zhanxi Fan Nailiang Yang Chaoliang Tan Lin Gu Jinlan Wang Hua Zhang | 2020 | Nano Research2020,13,7: | 2 |
| 13 | Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing显示文摘Complex oxides with tunable structures have many fascinating properties,though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach.Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic(1-x)BiTi(1-y)/2FeyMg(1-y)/2O3–(x)CaTiO3(BTFM–CTO)solid solution in large area,confirming its ferroelectricity at the atomic scale with strong spontaneous polarization.Careful compositional tuning leads to a bulk magnetization of 0.07±0.035μB/Fe at room temperature,enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0×10^-7 s/m.This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film,making it possible to explore a much wider space of composition,phase,and structure that can be easily scaled up for industrial applications. | Cong Liu Feng An Paria S.M.Gharavi Qinwen Lu Junkun Zha Chao Chen Liming Wang Xiaozhi Zhan Zedong Xu Yuan Zhang Ke Qu Junxiang Yao Yun Ou Zhiming Zhao Xiangli Zhong Dongwen Zhang Nagarajan Valanoor Lang Chen Tao Zhu Deyang Chen Xiaofang Zhai Peng Gao Tingting Jia Shuhong Xie Gaokuo Zhong Jiangyu Li | 2020 | National Science Review2020,7,1: | 2 |

| 15 | All in one theranostic nanoplatform enables efficient anti-tumor peptide I delivery for triple-modal imaging guided cancer therapy显示文摘Developing a reliable system to efficiently and safely deliver peptide drugs into tumor tissues still remains a great challenge since the instability of peptide drugs and low ability to traverse the cell membrane. Herein, we constructed a multifunctional nanoplatform based on porous europium/gadolinium (Eu/Gd)-doped NaLa(MoO4)2 nanoparticles (NLM NPs) to deliver antitumor peptide of B-cell lymphoma/leukemia-2-like protein 11 (BIM) for cancer therapy. The porous NLM NPs exhibited inherent photoluminescent, magnetic and X-ray absorbable properties, which enable them for triple-modal bioimaging, including fluorescence, magnetic resonance imaging (MRI) and computed tomography (CT). This triple-modal bioimaging can contribute to monitoring NLM NPs biodistribution and guiding therapy in vitro and in vivo. Furthermore, the NLM NPs showed negligible cytotoxicity in vitro and tissue toxicity in vivo. Importantly, NLM NPs could load the antitumor peptide of BIM and efficiently improve the resistance of peptide drugs to proteolysis. The BIM peptide was efficiently delivered into the tumor cells by NLM NPs, which can inhibit the growth and promote the apoptosis of cancer cells in vitro, significantly inhibit the tumor growth in vivo. Notably, NLM-BIM theranostic nanoplatform exhibits low systemic toxicity and fewer side effects in vivo. The NLM NPs can serve as a promising multifunctional peptide delivery nanoplatform for multi-modal bioimaging and cancer therapy. | Xiaoyan Qu Zhengqing Liu Bohan Ma Na Li Hongyang Zhao Tian Yang Yumeng Xue Xiaozhi Zhang Yongping Shao Ying Chang Jun Xu Bo Lei Yaping Du | 2019 | Nano Research2019,12,3: | 2 |
| 16 | Oxygen vacancies induced narrow band gap of BiOCl for efficient visible-light catalytic performance from double radicals显示文摘In this work,a high-efficiency photocatalytic BiOCl material with a visible light absorption range was successfully prepared by one-pot molecular self-assembly and particle recrystallization method at room temperature.In the process of crystal growth,tartaric acid,as a structure control agent,gradually transforms the stacked two-dimensional nano-sheet-like BiOCl into a hierarchical structure composed of petallike nano-sheets through hydrogen bonding.Besides,the acid etching of organic carboxylic acid on the crystal surface increases the number of micropores and mesopores,thereby the reaction interface.The thiourea(TU)molecules adsorbed on the BiOCl surface with a strong electronic effect introduce oxygen vacancies(OVs)under the condition of low oxygen content.The synergistic effect of hierarchical structure and OVs reduces the recombination of photogenerated carriers,but absorbs more O_(2)and OH−to generate a large number of superoxide radicals(·O_(2)−)and hydroxyl radicals(·OH)effectively.The photocatalytic performance of the synthesized BiOCl material has been significantly improved,and it can effectively degrade 94.15%of rhodamine B(RhB)within 20 min.Furthermore,90.95%of tetracycline(TC),93.76%of ciprofloxacin(CIP),and 85.53%of methyl orange(MO)can be removed in 80 min.Therefore,our work provides an effective method for preparing BiOCl with visible light catalytic activity,which,of course,can be used to treat and repair actual environmental problems under mild conditions. | Changyan Chen Ting Jiang Jianhua Hou Tingting Zhang Geshan Zhang Yongcai Zhang Xiaozhi Wang | 2022 | Journal of Materials Science & Technology2022,,19: | 2 |
| 17 | EXTENDED CORE STRUCTURE OF DISSOCIATED EDGE DISLOCATIONS IN FCC CRYSTALS WITH CONSIDERATION OF DISCRETENESS显示文摘The extended core structure of the dissociated edge dislocation in Al, Au, Ag, Cu and Ni is determined within lattice theory of dislocation. The 2D dislocation equation governing the displacements is coupled by the restoring forces that are determined by the parameterization of the generalized stacking fault energies. The Ritz variational method is presented to solve the dislocation equation and the trial solution is constituted by two arctan-type functions with two undetermined parameters. The core widths of partial dislocations are wider than that obtained in generalized Peierls-Nabarro model due to the consideration of discreteness of crystal. | Xiaozhi Wu Shaofeng Wang Huili Zhang | 2008 | Acta Mechanica Solida Sinica2008,21,5: | 1 |
