| 2 | 'Chameleon-like' optical behavior of lanthanide-doped fluoride nanoplates for multilevel anti-counterfeiting applications显示文摘Lanthanide-based luminescent anti-counterfeiting materials are widely used in various kinds of products.However,the emission color of traditional lanthanide-based luminescent materials usually remains nearly unaltered upon different excitation lights,which may only work for single-level anti-counterfeiting.Herein,the NaYbF4∶2%Er@NaYF4 core/shell nanoplates (NPs) with 'chameleon-like' optical behavior are developed.These NPs display single-band red or green downshifting (DS) emission upon excitation at 377 or 490 nm,respectively.Upon 980 nm excitation,the color of upconversion (UC) emission can be finely tuned from green to yellow,and to red with increasing the excitation power density from 0.1 to 4.0 W/cm^2.The proposed materials readily integrate the advantages of excitation wavelength-dependent DS single-band emissions and sensitive excitation power-dependent UC multicolor emissions in one and the same material,which has never been reported before.Particularly,the proposed NPs exhibit excellent performance as security labels on trademark tag and security ink on painting,thus revealing the great potential of these lanthanide-doped fluoride NPs in multilevel anti-counterfeiting applications. | Wenwu You Datao Tu Renfu Li Wei Zheng Xueyuan Chen | 2019 | Nano Research2019，12，6： | 3 |

| 4 | Highly efficient luminescent Ⅰ-Ⅲ-Ⅵ semiconductor nanoprobes based on template-synthesized CuInS2 nanocrystals显示文摘CuInS2 semiconductor nanocrystals (NCs) exhibit large absorption coefficient, size-dependent photoluminescence and low toxicity, making them excellent candidates in a variety of bioapplications. However, precise control of both their composition and morphology to improve the luminescent efficiency remains a great challenge via conventional direct synthesis. Herein, we present a novel low-temperature template synthesis of highly efficient luminescent CuInS2 nanoprobes from In2S3 NCs via a facile cation exchange strategy. The proposed strategy enables synthesis of a series of CuInS2 NCs with broad size tunability from 2.2 to 29.6 nm. Through rationally manipulating the stoichiometry of Cu/In, highly efficient luminescence of CuInS2 with the maximum quantum yield of 28.6% has been achieved, which is about one order of magnitude improvement relative to that of directly synthesized NCs. By virtue of the intense emission of CuInS2 nanoprobes, we exemplify their application in sensitive homogeneous biodetection for an important biomolecule of adenosine triphosphate (ATP) with the limit of detection down to 49.3 nM. Moreover, the CuInS2 nanoprobes are explored for ATP-targeted cancer cell imaging, thus revealing their great potentials in the field of cancer diagnosis and prognosis. | Xian Li Datao Tu Shaohua Yu Xiaorong Song Wei Lian Jiaojiao Wei Xiaoying Shang Renfu Li Xueyuan Chen | 2019 | Nano Research2019，12，8： | 3 |
| 5 | Porosity Effects on Mechanical Properties of 3D Random Fibrous Materials at Elevated Temperatures显示文摘In this study,we prepare the specimens of three-dimensional random fibrous(3D RF)material along its through-the-thickness(TTT)and in-plane(IP)directions.The experimental tests of tensile and compressive properties as well as fracture toughness of 3D RF material are performed at elevated temperatures.Then,the porosity(83%,87%and 89%)and temperature dependence of the tensile and compressive strength,elastic modulus,fracture toughness and fracture surface energy of the 3D RF materials for both the TTT and IP directions are analyzed.From the results of the tensile strength and elastic modulus versus material porosities at various temperatures,we find that tensile strength and elastic modulus for the TTT direction are more sensitive to the porosity,but not for the IP direction.Fracture toughness increases firstly and then decreases at a certain critical temperature.Such critical temperature is found to be the lowest for the porosity of 83%.On the other hand,at below 1073 K,the temperature-dependent fracture surface energies with three porosities for the TTT direction show similar variation trends. | Datao Li Wenshan Yu Wei Xia Qinzhi Fang Shengping Shen | 2020 | Acta Mechanica Solida Sinica2020，33，1： | 2 |
| 6 | Multiplexed intracellular detection based on dual-excitation/dualemission upconversion nanoprobes显示文摘Multiplexed intracellular detection is desirable in biomedical sciences for its higher eficiency and accuracy compared to the single-analyte detection.However,it is very challenging to construct nanoprobes that possess multiple fluorescent signals to recognize the different intracellular species synchronously.Herein,we proposed a novel dual-excitation/dual-emission upconversion strategy for multiplexed detection through the design of upconversion nanoparticles(UCNP)loaded with two dyes for sensitization and quenching of the upconversion luminescence(UCL),respectively.Based on the two independent energy transfer processes of near-infrared(NIR)dye IR845 to UCNP and UCNP to visible dye PAPS-Zn,CIO-and Zn2+were simultaneously detected with a limit of detection(LOD)of41.4 and 10.5 nM,respectively.By tilizing a purpose built 830/980 nm dual-laser confocal microscope,both intrinsic and exogenous CIO and Zn2+in live MCF-7 cells have been accurately quantified.Such dual-excitation/dual-emission ratiometric UCL detection mode enables not only monitoring multiple intracellular analytes but also eliminating the detection deviation caused by inhomogeneous probe distribution in cells.Through modulation of NIR dye and visible dye with other reactive groups,the nanoprobes can be extended to analyze various intraellular species,which provides a promising tool to study the biological activities in live cells and diagnose diseases. | Jianxi Ke Shan Lu Zhuo Li Xiaoying Shang Xingjun Li Renfu Li Datao Tu Zhuo Chen Xueyuan Chen | 2020 | Nano Research2020，13，7： | 2 |

| 9 | Exosomes from antler stem cells alleviate mesenchymal stem cell senescence and osteoarthritis显示文摘Dear Editor,Stem cell therapy holds enormous and revolutionary promise to treat various age-related diseases,such as diabetes,heart failure,and Parkinson’s disease.However,low retention and survival rate of delivered stem cells,partially due to immunological rejection,constitute major hurdles for the clinical implementation of stem cell therapy(Lei et al.,2021a).Since mounting evidence showed that several types of stem cells mainly exert their therapeutic effects through the secretion of paracrine effects,exosomes,which are released by stem cells and execute most paracrine functions,have begun to draw attention in the field(Tran and Damaser,2015).Exosomes are membrane-enclosed vesicles with an average diameter of∼100 nanometers secreted by the cells,containing cytokines. | Jinghui Lei Xiaoyu Jiang Wei Li Jie Ren Datao Wang Zhejun Ji Zeming Wu Fang Cheng Yusheng Cai Zheng-Rong Yu Juan Carlos Izpisua Belmonte Chunyi Li Guang-Hui Liu Weiqi Zhang Jing Qu Si Wang | 2022 | Protein & Cell2022，13，3： | 1 |
| 10 | Enhanced Speech Based Jointly Statistical Probability Distribution Function for Voice Activity Detection显示文摘Most of Voice activity detection(VAD)methods are based on statistical model.In these methods,the noise signal is always assumed to satisfy and characterized by Gaussian distribution,while the assumption of noise does not always hold in practice and which causes that these kinds of method fail to distinguish speech from noise at low Signal-noise-ratio(SNR) level in nonstationary noise condition.For going further to improve the robustness of VAD,a enhanced speech based method is proposed.In the proposed method,the Laplacian distribution is used to model the remained noise since we find that the remained noise in enhanced speech satisfy Laplacian distribution;in addition,Gaussian mixture model is used to characterize the Discrete Fourier transform(DFT)coefficients of reconstructed speech in enhanced speech.Experimental results show that the proposed method performs better than the baseline method,especially in low SNR and non-stationary noise conditions. | LI Jie YOU Datao | 2017 | Chinese Journal of Electronics2017，26，2： | 1 |
| 11 | Modulator-directed assembly of hybrid composites based on metalorganic frameworks and upconversion nanoparticles显示文摘Hybrid composites made of metal-organic frameworks(MOFs)and lanthanide-doped upconversion nanoparticles(UCNPs)have attracted considerable interest for their synergistically enhanced functions in various applications such as chemical sensing,photocatalysis,anticounterfeiting and nanomedicine.However,precise assembly of MOF/UCNP hybrid composites with tunable morphologies remains a challenge due to the lack of effective synthetic methods and fundamental understanding of the growth mechanisms.Herein,we propose a modulator-directed assembly strategy to synthesize a series of ZIF-8@UCNP composites(ZIF-8=zeolitic imidazolate framework-8).The UCNPs densely paved on the surface of ZIF-8 microcrystals and endowed the composites with intense upconversion blue emission,which were verified by steady-state/transient photoluminescence(PL)spectroscopy and single-particle imaging.Ethylenediamine(EDA)was firstly used as a modulator to fine-tune the predominant MOF facets and realized distinct morphologies of the composites.By adjusting the concentration of EDA from 0 to 25 mmol/L,the morphology of the ZIF-8@UCNP composites was tuned from rhombic dodecahedron(RD)to truncated rhombic dodecahedron(TRD),cube with truncated edges(CTE),cube,and finally a unique form of interpenetration twins(IT).The nucleation and growth process of the ZIF-8@UCNP composites was monitored by time-dependent scanning electron microscopy(SEM)images and the formation mechanism was thoroughly revealed.Furthermore,we demonstrated that the strategy for assembly of morphology-controllable ZIF-8@UCNP composites was generally applicable to various UCNPs with different sizes and shapes.The proposed strategy is expected to open up new avenues for the controllable synthesis of MOF/UCNP composites toward diverse applications. | Yanhui Feng Xingjun Li Shan Lu Renfu Li Zhongliang Gong Xiaoying Shang Yifan Pei Wei Zheng Datao Tu Xueyuan Chen | 2023 | Nano Research2023，16，1： | 0 |
| 12 | Temporoparietal Fascia Flaps for Surgical Treatment of Cartilage Exposure After the First-Stage Microtia Reconstruction显示文摘Significant improvements have been achieved in microtia reconstruction using an autogenous costal cartilage framework.However,complications such as skin necrosis and cartilage exposure often destroy the final contour of the reconstructed auricle.Local fascia flaps are commonly used in salvage surgery because of their reliability and satisfactory results.Here,we report the case of a 26-year-old woman with multiple skin necroses and cartilage exposure on day 21 after the first-stage microtia reconstruction.The exposure area was covered by a temporoparietal fascia flap as a single-stage procedure.The most essential subunits survived,and the esthetic concours were harmonious and natural at 12 months postoperatively.Temporoparietal fascia flaps are recommended as the surgical treatment for multiple skin necroses and cartilage exposure in microtia reconstruction.The axial-pattern temporoparietal fascia flap is reliable for salvage auricular reconstruction and ensures satisfactory results at long-term follow-up. | Zhicheng XU Ruhong ZHANG Qun ZHANG Feng XU Datao LI Yiyuan LI Xia CHEN | 2021 | Chinese Journal Of Plastic and Reconstructive Surgery2021，3，2： | 0 |
| 13 | Lanthanide-Doped Inorganic Nanoprobes for Luminescent Assays of Biomarkers显示文摘Tremendous progress in nanomaterial and nanotechnology has been made in recent years,which greatly contributes to the development of inorganic nanoparticles(NPs)as luminescent probes in diverse biomedical applications.In particular,these luminescent nanoprobes are widely employed for sensitive assays of biomarkers like disease markers.Generally,the luminescent bioassay technologies mainly rely on conventional molecular probes such as lanthanide(Ln3+)chelates or organic dyes,which suffer from inferior photochemical stability,low photobleaching,potential long-term toxicity,or high background noise.In contrast,Ln3+-doped NPs possess distinct physicochemical properties including better photostability,lower toxicity,and superior optical properties like long photoluminescent(PL)lifetime,narrow emission band,and tunable spectral range from the ultraviolet to the second near-infrared(NIR-II),which make them extremely ideal as luminescent nanoprobes.As such,enormous research enthusiasm has been invested in this fascinating field of Ln3+-doped luminescent nanoprobes in recent years.Accordingly,background-free luminescent bioassays with high signal-to-noise have been achieved by employing Ln3+-doped NPs on the basis of their downshifting luminescence(DSL)with a long PL lifetime,NIR-II luminescence with long-wavelength emissions,or upconverting luminescence(UCL)upon NIR excitation.However,there are still key challenges for Ln3+-doped nanoprobes owing to their low brightness and quantum yield,which restrict their biomedical applications.During the past decade,we have explored efficient approaches for the synthesis and design of highly efficient Ln3+-doped nanoprobes toward ultrasensitive luminescent bioassay of disease markers.In this Account,we summarize our most recent endeavors toward the development of inorganic Ln3+-doped NPs as sensitive nanoprobes for luminescent bioassays.First,we overview the approaches of controlled synthesis and optical manipulation to obtain highly efficient Ln3+-doped NPs with desirable optical properties.Second,we survey the design of Ln3+-doped nanoprobes with outstanding water dispersibility and excellent biocompatibility through surface functional bioconjugation of NPs.By employing these nanoprobes,we propose and exemplify several background-free luminescent bioassay strategies in an effort to suppress the interference of background noise from scattered lights and autofluorescence from biological samples.Third,we highlight the ultrasensitive bioassay of disease markers such as the time-resolved luminescent bioassay,NIR-II luminescent bioassay,and UCL bioassay.Finally,the major challenges,promising emerging trends,and future perspectives on this attractive field are discussed.Through this Account,we aim to offer a series of effective approaches to luminescent bioassay with high sensitivity and excellent specificity based on Ln3+-doped nanoprobes,which may broaden the roadway for clinical bioassays and accelerate the exploration of novel nanoprobes in versatile biomedical applications. | Luping Wang Siyuan Han Chenliang Li Datao Tu Xueyuan Chen | 2023 | Accounts of Materials Research2023，4，2： | 0 |
| 14 | Single-cell transcriptome reveals core cell populations and androgen-RXFP2 axis involved in deer antler full regeneration显示文摘Deer antlers constitute a unique mammalian model for the study of both organ formation in postnatal life and annual full regeneration.Previous studies revealed that these events are achieved through the proliferation and differentiation of antlerogenic periosteum(AP)cells and pedicle periosteum(PP)cells,respectively.As the cells resident in the AP and the PP possess stem cell attributes,both antler generation and regeneration are stem cell-based processes.However,the cell composition of each tissue type and molecular events underlying antler development remain poorly characterized.Here,we took the approach of single-cell RNA sequencing(scRNA-Seq)and identified eight cell types(mainly THY1^(+)cells,progenitor cells,and osteochondroblasts)and three core subclusters of the THY1^(+)cells(SC2,SC3,and SC4).Endothelial and mural cells each are heterogeneous at transcriptional level.It was the proliferation of progenitor,mural,and endothelial cells in the activated antler-lineage-specific tissues that drove the rapid formation of the antler.We detected the differences in the initial differentiation process between antler generation and regeneration using pseudotime trajectory analysis.These may be due to the difference in the degree of stemness of the AP-THY1+and PP-THY1^(+)cells.We further found that androgen-RXFP2 axis may be involved in triggering initial antler full regeneration.Fully deciphering the cell composition for these antler tissue types will open up new avenues for elucidating the mechanism underlying antler full renewal in specific and regenerative medicine in general. | Hengxing Ba Xin Wang Datao Wang Jing Ren Zhen Wang Hai-Xi Sun Pengfei Hu Guokun Zhang Shengnan Wang Chao Ma Yusu Wang Enpeng Wang Liang Chen Tianbin Liu Ying Gu Chunyi Li | 2022 | Cell Regeneration2022，11，1： | 0 |
| 15 | High areal capacity flexible sulfur cathode based on multi-functionalized super-aligned carbon nanotubes显示文摘Rational design of a robust carbon matrix has a profound impact on the performance of flexible/wearable lithium/sulfur batteries.Herein,we demonstrate a freestanding three-dimensional super-aligned carbon nanotube (SACNT) matrix reinforced with a multi-functionalized carbon coating for flexible,high-areal sulfur loading cathode.By employing the sulfur/nitrogen co-doped carbon (SNC)'glue',the joints in the SACNT scaffold are tightly welded together so that the overall mechanical strength of the electrode is significantly enhanced to withstand the repeated bending as well as the volume change during operation.The SNC also shows intriguing catalytic effect that lowers the energy barrier of Li ion transport,propelling a superior redox conversion efficiency.The resulting binder-free and current collector-free sulfur cathode exhibits a high reversible capacity of 1,079 mAh·g^-1 at 1 C,a high-rate capacity of ~ 800 mAh·g^-1 at 5 C,and an average capacity decay rate of 0.037% per cycle at 2 C for 1,500 cycles.Impressively,a large-areal flexible Li/S pouch cell based on such mechanically robust cathode exhibits excellent capacity retention under arbitrary bending conditions.With a high areal sulfur loading of 7 mg·cm^-2,the large-areal flexible cathode delivers an outstanding areal capacity of 6.3 mAh·cm^-2 at 0.5 C (5.86 mA·cm^-2),showing its promise for realizing practical high energy density flexible Li/S batteries. | Lujie Jia Jian Wang Zijin Chen Yipeng Su Wei Zhao Datao Wang Yang Wei Kaili Jiang Jiaping Wang Yang Wu Jia Li Wenhui Duan Shoushan Fan Yuegang Zhang | 2019 | Nano Research2019，12，5： | 0 |

| 17 | Comparison of Biomechanical Characteristics during the Second Landing Phase in Female Latin Dancers:Evaluation of the Bounce and Side Chasse Step显示文摘Research on dance lower extremity joint motion has been limited.Thus,the purpose of this study was to investigate the lower limb biomechanics differences between the side chasse step(SCS)and the bounce step(BS)of the second landing phase in Jive.Thirteen female recreational Latin dancers(Age:22±2.5 years;Height:1.65±0.05 m;Weight:50±4.5 kg;Dance experience:4±2 years)were involved in the experiment.The same music was used throughout the data collection period.We intended to determine whether these two steps generate different kinematic and kinetic data.The ankle,hip,and knee joint angle,moment,velocity,and ground reaction force were calculated for each step.Results demonstrated that the lower limb biomechanics of the two different steps showed significant differences.As a result,strengthening the lower limb muscles(gastrocnemius,Tibialis muscle,and quadriceps)is significantly important to balance the joint strength and prevent foot injury.According to the training time reasonably increasing the heel height should be recognized as important.The current study could provide new insights into reducing lower extremity injuries and improving dance performance. | Fengfeng Li Huiyu Zhou Datao Xu Julien S.Baker Yaodong Gu | 2022 | Molecular & Cellular Biomechanics2022，19，3： | 0 |
| 18 | Luminescent nano-bioprobes based on NIR dye/lanthanide nanoparticle composites显示文摘Near-infrared(NIR)light,which has ignorable tissue scattering/absorption,minimal photodamage,and no autofluorescence interference,is highly favorable for bioapplications.NIR dye and lanthanide-doped nanoparticle(LnNP),as representative NIR-excited luminescence probes,have attracted increasing interest due to their unique optical property and low biological toxicity.Design of luminescence probes based on NIR dye/LnNP nanocomposites cannot only integrate the advantages but also achieve additional functions via regulating internal energy transfer pathways.In this review,we focus on the most recent advances in the development of NIR dye/LnNP nanocomposites as potential bioprobes,which cover from their fundamental photophysics to bioapplications,including energy transfer mechanisms,interface engineering(involving binding interaction,distance,and aggregation as key factors),and their applications for dye-sensitized upconversion/downshifting luminescent bioimaging,detection of biomolecules,and NIR-triggered diagnosis and therapy.Some future prospects and efforts toward this active research field are also envisioned. | Shan Lu Jianxi Ke Xingjun Li Datao Tu Xueyuan Chen | 2021 | Aggregate2021，2，5： | 0 |
| 19 | Boosting the Energy Migration Upconversion through Inter-Shell Energy Transfer in Tb^(3+)-Doped Sandwich Structured Nanocrystals显示文摘It remained challenging to fabricate Tb^(3+)-doped lanthanide nanocrystals(NCs)to simultaneously acquire strong energy migration upconversion(EMU)emissions of Tb^(3+)while suppressing the Tm3+UV upconversion emissions that cause background biofluorescence issues in bioapplications based on Tb^(3+)-doped EMU NCs.Herein,we report a novel sandwich structured core@shell@shell scheme for the design of EMU NCs,for example,NaLuF4∶Yb/Gd@NaGdF4∶Tm@NaLuF4∶Tb NCs,wherein Yb^(3+),Tm^(3+),and Tb^(3+)are incorporated separately into the inner core,middle shell,and outer shell,respectively.We found that in the sandwich structured NCs,the effective inter-shell energy transfer from Gd^(3+)in the middle shell to Tb^(3+)in the outer shell accelerated the Yb^(3+)-Tm^(3+)five-photon upconversion and the subsequent Tm^(3+)to Gd^(3+)energy transfer processes,which could eventually lead to almost complete inhibition of Tm^(3+)UV upconversion emissions,concurrent with the strong EMU emissions of Tb^(3+).Our findings might stimulate new concepts for manipulating upconversion emissions of lanthanide NCs. | Dan Xu Jin Xu Xiaoying Shang Shaohua Yu Wei Zheng Datao Tu Renfu Li Xueyuan Chen | 2022 | CCS Chemistry2022，4，6： | 0 |
