| 1 | One-Pot Synthesis and Strong Near-Infrared Upconversion Luminescence of Poly(acrylic acid)-Functionalized YF3:Yb^(3+)/Er^(3+) Nanocrystals显示文摘This paper describes the synthesis of new upconverting luminescent nanoparticles that consist of YF_(3):Yb^(3+)/Er^(3+)functionalized with poly(acrylic acid)(PAA).Unlike the upconverting nanocrystals previously reported in the literature that emit visible(blue-green-red)upconversion fluorescence,these as-prepared nanoparticles emit strong near-infrared(NIR,831 nm)upconversion luminescence under 980 nm excitation.Scanning electron microscopy,transmission electron microscopy,and powder X-ray diffraction were used to characterize the size and composition of the luminescent nanocrystals.Their average diameter was about 50 nm.The presence of the PAA coating was confirmed by infrared spectroscopy.The particles are highly dispersible in aqueous solution due to the presence of carboxylate groups in the PAA coating.By carrying out the synthesis in the absence of PAA,YF_(3):Yb^(3+)/Er^(3+)nanorice materials were obtained.These nanorice particles are larger(~700 nm in length)than the PAA-functionalized nanoparticles and show strong typical visible red(668 nm),rather than NIR(831 nm),upconversion fluorescence.The new PAA-coated luminescent nanoparticles have the pottential be used in a variety of bioanalytical and medical assays involving luminescence detection and fluorescence imaging,especially in vivo fluorescence imaging,due to the deep penetration of NIR radiation. | Leyu Wang Yi Zhang Yanyu Zhu | 2010 | Nano Research2010，3，5： | 13 |

| 3 | Heredity in the Microstructure and Mechanical Properties of Hot-rolled Spring Steel Wire 60Si2MnA during Heat Treatment Process显示文摘Heredity in the microstructure and mechanical properties of hot-rolled spring steel wire 60Si2MnA during heat treatment process was investigated comprehensively. The steel was isothermally transformed to obtain various hot-rolled microstructure (pearlite fineness within the range of 140-510 nm) and mechanical properties, and followed by some quenching-tempering treatment. Afterwards, microstructure was characterized by optical microscopy, scanning electron microscopy and quantitative metallography, and mechanical properties were determined by tensile test. The results indicated that the hot-rolled microstructure with a coarsen pearlite structure had been changed after reheating, to a austenite microstructure with bigger and more uneven grain size, and finally to a coarsen tempered microstructure. And the average austenite grain size and standard deviation of its distribution in quenched microstructure were observed to depend linearly on the interlamellar spacing in hot-rolled microstructure. Besides, to obtain a good combination of the final strength and plasticity, an optimum value range (190-280 nm) of the interlamellar spacing had been determined for the interlamellar spacing in hot-rolled microstructure. | Chaolei Zhang Leyu Zhou Yazheng Liu | 2013 | Journal of Materials Science & Technology2013，29，1： | 9 |
| 4 | 3D nickel-cobalt diselenide nanonetwork for highly efficient oxygen evolution显示文摘Active, stable and low-cost oxygen evolution reaction(OER) catalyst for electrochemical water splitting is key to efficient energy conversion and storage. Here, we report a three-dimensional(3D) nanonetwork as noble-metal-free electrode consisting of nickel cobalt diselenide(NiCoSe_2) nanobrush arrays on Ni foam(NF) through the initial hydrothermal reaction and subsequent thermal selenization process. Introducing ammonium fluoride as surface controller, different NiCoSe_2 hierarchical architecture can be modulated from nanorods, nanobrush to nanosheets. The unique brush-like NiCoSe_2 possesses high surface area for mass transfer, rough surface with rich active sites, 3D nanostructure preventing the accumulation of O2 bubbles. Compared to NiCoSe_2 nanorods/NF, NiCoSe_2 nanosheets/NF and commercial Ru O2,NiCoSe_2 nanobrush/NF exhibits an enhanced OER performance in alkaline media to reach a low overpotential of 274 m V at the current density of 10 m A/cm2, small Tafel slope and a long-term stability. The developed 3D nanonetwork highlights the nanoscale engineering and offers a promising alternative to noble metal catalysts for electrochemical water oxidation. | Hengli Zhu Rui Jiang Xiaoqing Chen Yueguang Chen Leyu Wang | 2017 | Science Bulletin2017，62，20： | 7 |

| 7 | Preparation and upconversion luminescence cell imaging of O-carboxymethyl chitosan-functionalized NaYF_4:Yb^(3+)/Tm^(3+)/Er^(3+) nanoparticles显示文摘Upconversion luminescence nanoparticles(UCNPs)have shown promising applications in biomedical fields as luminescent probes because of their excellent advantages such as single excitation with multicolor emission,low autofluorescence,and deep penetration.But the biological applications of such nanomaterials are still restricted due to the unfavorable surface properties.In this work,we develop a facile one-pot hydrothermal route to obtain O-carboxymethyl chitosan(OCMC)-wrapped NaYF4:Yb3+/Tm3+/Er3+red UCNPs which have been used for targeted cell luminescence imaging directly and efficiently.The successful coating of the UCNPs by OCMC has been confirmed by Fourier-transform infrared(FTIR)spectroscopy and dynamic light scattering(DLS)studies.Transmission electron microscopy(TEM),powder X-ray diffraction(XRD),thermogravimetric analysis(TGA),and photoluminescence(PL)spectra have been used to characterize the size,composition and emission color of the samples,respectively.Due to the good biocompatibility,water-solubility,and strong UC luminescence,these hydrophilic nanocrystals will open up new avenues in further bioapplications. | LI Hao WANG LeYu | 2013 | Chinese Science Bulletin2013，58，33： | 5 |
| 8 | Microstructure Control of Non-quenched and Tempered CT80Grade Coiled Tubing Steel显示文摘Complex working condition of coiled tube(CT) steel demands high strength and low ratio of yield strength(YS) to tensile strength(TS). Reasonable microstructure control is a key problem of CT steel. Controlled rolling and controlled cooling experiments were carried out by two kinds of tested steels with different chemical compositions to develop the non-quenched and tempered CT80 steel. Mechanical properties of the tested steels at different processes are all in good agreement with the properties requirement of CT80. Increasing of Mo and Nb contents improves transformation of acicular ferrite and martensite–austenite(M–A) islands. 4 vol% of fine M/A islands increase TS and decreases ratio of YS/TS. Cooling rate increasing also improves acicular ferrite transformation and enhances TS, but has little effect on ratio of YS/TS. To meet the requirement of high strength and low ratio of YS/TS, optimized complex microstructure of the CT80 steel is composed of acicular ferrite, about 30 vol% of bainite and 4 vol% of M–A islands. | Leyu Zhou Bo Jiang Mingyang Li Fuchun Yuan Chaolei Zhang Yazheng Liu | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，3： | 5 |

| 10 | Heat Treatment Properties of 42CrMo Steel for Bearing Ring of Varisized Shield Tunneling Machine显示文摘The heat treatment properties of 42 CrMo steel for bearing ring of varisized shield tunneling machine were investigated by optical microscope(OM), scanning electron microscope(SEM), transmission electron microscope(TEM),and impact tests. The addition of 0.03 wt% C into 42 CrMo steel can increase the hardness. But it reduces the impact energy by 46 J because of the appearance of coarser carbides in the matrix and the carbides along the austenite grain boundary.The addition of 0.40 wt% Mn into 42 CrMo steel can improve hardenability. However, the toughness of steel is also reduced by 26 J mainly because of the coarsening of carbides and the strengthening of matrix. Both hardenability and toughness of 42 CrMo steel can be improved by adding 1.49 wt% Ni and reducing 0.32 wt% Cr. The depth of hardening layer can be raised to 45 mm, and the impact energy at-20 °C is 120 J. Thus, it is concluded that a good combination of hardness, hardenability, and toughness of 42 CrMo steel can be achieved by alloying with adding some content of C and Ni.Detailed content of C and Ni should be on the requirements of heat treatment properties of steel for bearing ring of varisized shield tunneling machine. | Bo Jiang Leyu Zhou Xinli Wen Chaolei Zhang Yazheng Liu | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，3： | 3 |
| 11 | Self-assembled monolayer enabling improved buried interfaces in blade-coated perovskite solar cells for high efficiency and stability显示文摘Despite the rapidly increased power conversion efficiency(PCE)of perovskite solar cells(PVSCs),it is still quite challenging to bring such promising photovoltaic technology to commercialization.One of the challenges is the upscaling from small-sized lab devices to large-scale modules or panels for production.Currently,most of the efficient inverted PVSCs are fabricated on top of poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine](PTAA),which is a commonly used hole-transporting material,using spin-coating method to be incompatible with large-scale film deposition.Therefore,it is important to develop proper coating methods such as blade-coating or slot-die coating that can be compatible for producing large-area,high-quality perovskite thin films.It is found that due to the poor wettability of PTAA,the blade-coated perovskite films on PTAA surface are often inhomogeneous with large number of voids at the buried interface of the perovskite layer.To solve this problem,self-assembled monolayer(SAM)-based hole-extraction layer(HEL)with tunable headgroups on top of the SAM can be modified to provide better wettability and facilitate better interactions with the perovskite coated on top to passivate the interfacial defects.The more hydrophilic SAM surface can also facilitate the nucleation and growth of perovskite films fabricated by blade-coating methods,forming a compact and uniform buried interface.In addition,the SAM molecules can also be modified so their highest occupied molecular orbital(HOMO)levels can have a better energy alignment with the valence band maxima(VBM)of perovskite.Benefitted by the high-quality buried interface of perovskite on SAM-based substrate,the champion device shows a PCE of 18.47%and 14.64%for the devices with active areas of 0.105 cm^(2) and 1.008 cm^(2),respectively.In addition,the SAM-based device exhibits decent stability,which can maintain 90%of its initial efficiency after continuous operation for over 500 h at 40℃ in inert atmosphere.Moreover,the SAM-based perovskite mini-module exhibits a PCE of 14.13%with an aperture area of 18.0 cm^(2).This work demonstrates the great potential of using SAMs as efficient HELs for upscaling PVSCs and producing high-quality buried interface for large-area perovskite films. | Jie Zeng Leyu Bi Yuanhang Cheng Baomin Xu Alex K.-Y.Jen | 2022 | Nano Research Energy2022，1，1： | 3 |
| 12 | From waste of marine culture to natural patch in cardiac tissue engineering显示文摘Sea squirt,as a highly invasive species and main biofouling source in marine aquaculture,has seriously threatened the biodiversity and aquaculture economy.On the other hand,a conductive biomaterial with excellent biocompatibility,and appropriate mechanical property from renewable resources is urgently required for tissue engineering patches.To meet these targets,we presented a novel and robust strategy for sustainable development aiming at the marine pollution via recycling and upgrading the waste biomass-sea squirts and serving as a renewable resource for functional bio-scaffold patch in tissue engineering.We firstly demonstrated that the tunic cellulose derived natural self-conductive scaffolds successfully served as functional cardiac patches,which significantly promote the maturation and spontaneous contraction of cardiomyocytes both in vitro and enhance cardiac function of MI rats in vivo.We believe this novel,feasible and“Trash to Treasure”strategy to gain cardiac patches via recycling the waste biomass must be promising and beneficial for marine environmental bio-pollution issue and sustainable development considering the large-scale consumption potential for tissue engineering and other applications. | Yutong He Honghao Hou Shuqi Wang Rurong Lin Leyu Wang Lei Yu Xiaozhong Qiu | 2021 | Bioactive Materials2021，6，7： | 2 |
| 13 | Porous N-doped-carbon coated CoSe2 anchored on carbon cloth as 3D photocathode for dye-sensitized solar cell with efficiency and stability outperforming Pt显示文摘Photocathode with superior catalytic activity,long-term stability,and fast mass/electron transfer is highly desirable but challenging for dye-sensitized solar cell(DSC).Herein,the ZIF-67 grown on carbon cloth is successfully transformed into CoSe2 embedded in N-doped carb on nano cage(CoSe2/N-C)via a growth-carbonization-selenization process.The carb on cloth supported CoSe2/N-C,as photocathode of DSC,demonstrates a good long-term stability and high photovoltaic efficiency(8.40%),outperforming Pt.The good efficiency can be attributed to the high catalytic activity of CoSe2,fast mass tran sfer of porous three-dimensi on al(3D)structure,and good electr on transport derived from the intimate con tact between CoSe2 and highly conductive carb on cloth.The high stability would be ascribed to N-doped carbon coating that perfectly prevents CoSe2 from decomposition.This work will pave the way to develop highly efficient and stable Pt-free photocathode for DSC. | Wenli Lu Rui Jiang Xiong Yin Leyu Wang | 2019 | Nano Research2019，12，1： | 2 |
| 14 | Modeling De-No_(x) by Injection Ammonia in High Temperature Zone of Cement Precalciner显示文摘The quantity of NO_(x) emission from cement production is second only to thermal power generation and vehicle exhaust.In this paper,a phenomenon found by Taniguchi is used to achieve NO_(x) reduction in the cement precalciner.Based on his results,it is proposed to reduce NO_(x) that ammonia is injected in the high-temperature and lean-oxygen zone(HT-DeNO_(x))during pulverized coal combustion.For a large cement precalciner(3200 t/d),numerical simulation is used to evaluate the technology of HT-DeNO_(x) combined with the traditional selective non-catalytic reduction(SNCR)method.The results indicate that NH3 and HCN in HT-DeNO_(x) can reduce NO during the reaction process.With very little ammonia injection(normalized stoichiometric ratio NSR=0.1,the normalized stoichiometric ratio),the efficiency of NO reduction by HT-DeNO_(x) is 27.72%.Combining SNCR(NSR=1.1)and HT-DeNO_(x)(NSR=0.1),the reduction efficiency will be improved to 60.05%,compared with 50.83%efficiency when using only SNCR at NSR=1.2. | ZHANG Leyu WEI Xiaolin ZHANG Zhongxiao LI Sen | 2021 | Journal of Thermal Science2021，30，2： | 2 |
