| 2 | Hierarchical ZSM-11 with intergrowth structures:Synthesis,characterization and catalytic properties显示文摘Hierarchical ZSM-11 microspheres with intercrystalline mesoporous properties and rod-like crystals intergrowth morphology have been synthesized using a spot of tetrabutylammonium as a single template.XRD,FTIR,SEM,TEM and N2 adsorption analysis revealed that each individual particle was composed of nanosized rod crystals inserting each other and the intercrystalline voids existing among rods gave a significant mesopore size distribution.Steam treatment result demonstrated the excellent hydrothermal stability of samples.Various crystallization modes including constant temperature crystallization (one-stage crystallization) and two-stage temperature-varying crystallization with different 1st stage durations were investigated.The results suggested that the crystallization modes were mainly responsible for the adjustable particle size and textural properties of samples while the small amount of tetrabutylammonium bromide was mainly used to direct the formation of both ZSM-11 framework and its intergrowth morphology.Furthermore,the performance of optimal ZSM-11 as an active component for the catalytic pyrolysis of heavy oil was also investigated.Compared with the commercial pyrolysis catalyst,the hierarchical ZSM-11 catalyst exhibited a high selectivity to desired products(LPG+gasoline+diesel),as well as a much lower dry gas and coke yield,plus a high selectivity and yield of light olefins(C=3 C=4)and very poor selectivity to benzene.Therefore,fully open micropore-mesopore connectivity would make such hierarchically porous ZSM-11 zeolites very attractive for applications in clean petrochemical catalysis field. | Qingjun Yu Chaoyue Cui Qiang Zhang Jing Chen Yang Li Jinpeng Sun Chunyi Li Qiukai Cui Chaohe Yang Honghong Shan | 2013 | Journal of Energy Chemistry2013,22,5: | 10 |
| 3 | High-performance silicon−graphene hybrid plasmonic waveguide photodetectors beyond 1.55μm显示文摘Graphene has attracted much attention for the realization of high-speed photodetection for silicon photonics over a wide wavelength range.However,the reported fast graphene photodetectors mainly operate in the 1.55μm wavelength band.In this work,we propose and realize high-performance waveguide photodetectors based on bolometric/photoconductive effects by introducing an ultrathin wide silicon−graphene hybrid plasmonic waveguide,which enables efficient light absorption in graphene at 1.55μm and beyond.When operating at 2μm,the present photodetector has a responsivity of ~70 mA/W and a setup-limited 3 dB bandwidth of >20 GHz.When operating at 1.55μm,the present photodetector also works very well with a broad 3 dB bandwidth of >40 GHz(setup-limited)and a high responsivity of ~0.4 A/W even with a low bias voltage of−0.3 V.This work paves the way for achieving highresponsivity and high-speed silicon-graphene waveguide photodetection in the near/mid-infrared ranges,which has applications in optical communications,nonlinear photonics,and on-chip sensing. | Jingshu Guo Jiang Li Chaoyue Liu Yanlong Yin Wenhui Wang Zhenhua Ni Zhilei Fu Hui Yu Yang Xu Yaocheng Shi Yungui Ma Shiming Gao Limin Tong Daoxin Dai | 2020 | Light(Science & Applications)2020,9,1: | 10 |
| 4 | Simulation and Field Testing of Multiple Vehicles Collision Avoidance Algorithms显示文摘A global planning algorithm for intelligent vehicles is designed based on the A* algorithm, which provides intelligent vehicles with a global path towards their destinations. A distributed real-time multiple vehicle collision avoidance(MVCA)algorithm is proposed by extending the reciprocal n-body collision avoidance method. MVCA enables the intelligent vehicles to choose their destinations and control inputs independently,without needing to negotiate with each other or with the coordinator. Compared to the centralized trajectory-planning algorithm, MVCA reduces computation costs and greatly improves the robustness of the system. Because the destination of each intelligent vehicle can be regarded as private, which can be protected by MVCA, at the same time MVCA can provide a real-time trajectory planning for intelligent vehicles. Therefore,MVCA can better improve the safety of intelligent vehicles. The simulation was conducted in MATLAB, including crossroads scene simulation and circular exchange position simulation. The results show that MVCA behaves safely and reliably. The effects of latency and packet loss on MVCA are also statistically investigated through theoretically formulating broadcasting process based on one-dimensional Markov chain. The results uncover that the tolerant delay should not exceed the half of deciding cycle of trajectory planning, and shortening the sending interval could alleviate the negative effects caused by the packet loss to an extent. The cases of short delay(< 100100 ms) and low packet loss(< 5%) can bring little influence to those trajectory planning algorithms that only depend on V2 V to sense the context, but the unpredictable collision may occur if the delay and packet loss are further worsened. The MVCA was also tested by a real intelligent vehicle, the test results prove the operability of MVCA. | Chaoyue Zu Chao Yang Jian Wang Wenbin Gao Dongpu Cao Fei-Yue Wang | 2020 | IEEE/CAA Journal of Automatica Sinica2020,7,4: | 6 |
| 5 | Microfluidic 3D printing polyhydroxyalkanoates-based bionic skin for wound healing显示文摘Biomimetic scaffolds with extracellular matrix(ECM)-mimicking structure have been widely investigated in wound healing applications,while insufficient mechanical strength and limited biological activity remain major challenges.Here,we present a microfluidic 3D printing biomimetic polyhydroxyalkanoates-based scaffold with excellent mechanical properties and hierarchical porous structures for enhanced wound healing.This scaffold is composed of poly(3-hydroxybutyrate-4-hydroxybutyrate)and polycaprolactone,endowing it with excellent tensile strength(2.99 MPa)and degradability(80%of weight loss within 7 d).The ECM-mimicking hierarchical porous structure allows bone marrow mesenchymal stem cells(BMSCs)and human umbilical vein endothelial cells(HUVECs)to proliferate and adhere on the scaffolds.Besides,anisotropic composite scaffolds loaded with BMSCs and HUVECs can significantly promote re-epithelization,collagen deposition and capillary formation in rat wound defects,indicating their satisfactory in vivo tissue regenerative activity.These results indicate the feasibility of polyhydroxyalkanoates-based biomimetic scaffolds for skin repair and regeneration,which also provide a promising therapeutic strategy in diverse tissue engineering applications. | Wentai Guo Xiaocheng Wang Chaoyu Yang Rongkang Huang Hui Wang Yuanjin Zhao | 2022 | Materials Futures2022,1,1: | 1 |
| 6 | PD0325901, an ERK inhibitor, enhances the efficacy of PD-1 inhibitor in non-small cell lung carcinoma显示文摘ERK pathway regulated the programmed death ligand-1(PD-L1)expression which was linked to the response of programmed death-1(PD-1)/PD-L1 blockade therapy.So it is deducible that ERK inhibitor could enhance the efficacy of PD-1 inhibitor in cancer immunotherapy.In this study,PD0325901,an oral potent ERK inhibitor,strongly enhanced the efficacy of PD-1 antibody in vitro and in vivo models in non-small cell lung carcinoma(NSCLC)cells.Mechanistically,PD0325901 or shRNA-ERK1/2 significantly downregulated the PD-L1 expression in NSCLC cells and increased the CD3+T cells infiltration and functions in tumor tissue.There was a positive correlation between the p-ERK1/2 expression and PD-L1 expression in patients with NSCLC.And the patients with low p-ERK1/2 expression were observed a high response rate of PD-1/PD-L1 blockage therapy.Our results demonstrate that PD0325901,an ERK inhibitor,can enhance the efficacy of PD-1 blockage against NSCLC in vitro and in vivo models.And the combination of ERK inhibitor such as PD0325901 and PD-1/PD-L1 blockage is a promising regimen and encouraged to be further confirmed in the treatment of patients with NSCLC. | Min Luo Yuhui Xia Fang Wang Hong Zhang Danting Su Chaoyue Su Chuan Yang Shaocong Wu Sainan An Suxia Lin Liwu Fu | 2021 | Acta Pharmaceutica Sinica B2021,11,10: | 1 |
| 7 | Twinning,phase boundary structure and development of high coercivity in Fe-rich Sm_(2)Co_(17)-type magnets显示文摘The microstructure of twinning as well as the phase boundary between 1:5 H and 2:17 R phase in Fe-rich Sm_(2)Co_(17)-type magnets was characterized at atomic scale using nanobeam diffraction and highresolution STEM-HAADF imaging,and the reason for the dramatic increase of coercivity during slow cooling was investigated based on the microchemistry analysis.The twinning relationship in the 2:17 R phase originates from ordered substitution of Sm atoms by Co-Co atomic pairs on every three(3033)and(3033)planes,leading to formation of two corresponding equivalent twin variants.The basal plane of the 2:17 R phase,the 1:3 R platelet phase across the 2:17 R cell and the 1:5 H cell boundary phase between two adjacent 2:17 R cells all can act as effective twin boundary.The cell boundary phase is precipitated along the pyramidal habit plane,and a fully coherent phase boundary(PB)is formed between the 1:5 H and 2:17 R phases with the orientation relationship to be PB//(1121)1:5 H//(1011)_(2):17 R.The phase boundary may either be parallel to or intersect with the pyramidal planes occupied by Co-Co atomic pairs.The substantial increase of coercivity during slow cooling is ascribed to the development of large gradient of the elements concentration within the cell boundary phase,resulting in large gradient of domain wall energy,and thus the pinning strength of the cell boundary phase against magnetic domain wall motion is significantly enhanced. | Haichen Wu Zhuang Liu Chaoyue Zhang Qiqi Yang Huanming Lu Guoxin Chen Xinming Wang Yong Li Renjie Chen Aru Yan | 2022 | Journal of Rare Earths2022,40,1: | 1 |
| 8 | FeCo-based mesoporous carbon shells modified N-doped porous carbon spheres for oxygen reduction reaction显示文摘Fe Co-based non-noble metal electrocatalysts(NNMEs)of Fe Co/MCS-NPCS was fabricated by immobilization of hemin on mesoporous carbon shells modified N-doped porous carbon spheres(MCS-NPCS).The obtained Fe Co/MCS-NPCS exhibits a half-wave potential(E1/2)of 0.851 V versus the reversible hydrogen electrode(vs.RHE)and a limited-diffusion current density(JL)of 5.45 m A cm^(-2).In addition,Fe Co/MCS-NPCS shows comparable oxygen reduction reaction(ORR)performances to 20 wt%Pt/C in terms of E1/2 and JL and better electrochemical properties,including the methanol tolerance and durability in alkaline solution.Such outstanding electrochemical activities of Fe Co/MCS-NPCS can be ascribed to Fe and/or Co-based nitrides and carbides as well as N-doped carbon matrixes modified with mesoporous carbon shells.This research introduces a promising path to design and synthesize highly efficient Fe Co–N–C electrocatalysts towards ORR. | Xinxin Jin Yan Xie Chaoyue Zhao Yinghao Xu Yang Lv He Wang Li Chen Jiahui Huang | 2021 | Progress in Natural Science:Materials International2021,31,4: | 1 |
| 9 | Revealing the correlation between structure evolution and electrochemical performance of high-voltage lithium cobalt oxide显示文摘Lithium cobalt oxide(LCO)is the dominating cathode materials for lithium-ion batteries(LIBs)deployed in consumer electronic devices for its superior volumetric energy density and electrochemical performances.The constantly increasing demands of higher energy density urge to develop high-voltage LCO via a variety of strategies.However,the corresponding modification mechanism,especially the influence of the long-and short-range structural transitions at high-voltage on electrochemical performance,is still not well understood and needs further exploration.Based on ss-NMR,in-situ X-ray diffraction,and electrochemical performance results,it is revealed that the H3 to H1-3 phase transition dictates the structural reversibility and stability of LCO,thereby determining the electrochemical performance.The introduction of La and Al ions could postpone the appearance of H1-3 phase and induce various types of local environments to alleviate the volume variation at the atomic level,leading to better reversibility of the H1-3 phase and smaller lattice strain,and significantly improved cycle performance.Such a comprehensive long-range,local,and electronic structure characterization enables an in-depth understanding of the structural evolution of LCO,providing a guiding principle for developing high-voltage LCO for high energy density LIBs. | Jiajia Wan Jianping Zhu Yuxuan Xiang Guiming Zhong Xiangsi Liu Yixiao Li Kelvin H.L.Zhang Chaoyu Hong Jianming Zheng Kai Wang Yong Yang | 2021 | Journal of Energy Chemistry2021,30,3: | 1 |
| 10 | In Situ 3D Bioprinting Living Photosynthetic Scaffolds for Autotrophic Wound Healing显示文摘Three-dimensional(3D)bioprinting has been extensively explored for tissue repair and regeneration,while the insufficient nutrient and oxygen availability in the printed constructs,as well as the lack of adaptive dimensions and shapes,compromises the overall therapeutic efficacy and limits their further application.Herein,inspired by the natural symbiotic relationship between salamanders and algae,we present novel living photosynthetic scaffolds by using an in situ microfluidic-assisted 3D bioprinting strategy for adapting irregular-shaped wounds and promoting their healing.As the oxygenic photosynthesis unicellular microalga(Chlorella pyrenoidosa)was incorporated during 3D printing,the generated scaffolds could produce sustainable oxygen under light illumination,which facilitated the cell proliferation,migration,and differentiation even in hypoxic conditions.Thus,when the living microalgae-laden scaffolds were directly printed into diabetic wounds,they could significantly accelerate the chronic wound closure by alleviating local hypoxia,increasing angiogenesis,and promoting extracellular matrix(ECM)synthesis.These results indicate that the in situ bioprinting of living photosynthetic microalgae offers an effective autotrophic biosystem for promoting wound healing,suggesting a promising therapeutic strategy for diverse tissue engineering applications. | Xiaocheng Wang Chaoyu Yang Yunru Yu Yuanjin Zhao | 2022 | Research2022,,3: | 1 |
| 11 | Comparison of the meat quality and fatty acid profile of muscles in finishing Xiangcun Black pigs fed varied dietary energy levels显示文摘To study the effects of dietary energy level on the meat quality of different muscles in finishing pigs,400Xiangcun Black pigs(BW=79.55±4.77 kg)were randomly assigned to 5 treatments with varied calculated digestive energy(DE)at 3,050,3,100,3,150,3,200 and 3,250 kcal/kg,respectively.Each treatment had 8replicates with 10 pigs per replicate.Meat quality,amino acid and fatty acid composition were tested in this study.No differences in average daily gain,average daily feed intake or feed-to-gain ratio(P>0.05)were observed among dietary treatments.Glycogen concentrations of longissimus dorsi(LD)muscle in DE3150was higher than those in other groups(P<0.05).The crude fat concentration of biceps femoris(BF)muscle in DE3250 tended to be higher than that in DE3150 and DE3100 groups(P<0.05).Pigs in DE3250 and DE3200 had higher fiber density and smaller cross-sectional area of BF muscle than those in DE3150(P<0.05).Pigs in DE3150 had the highest Cu concentration in LD muscle compared with those in DE3200,DE3250(P<0.05).The C16:1 proportion of LD muscle was lower(P<0.01)and C20:1 was higher(P<0.05)in DE3050 than that in the other dietary treatments.The C18:3n6 and C20:3n6 proportions of BF muscle in DE3150 were higher than those in DE 3050,DE3200 and DE3250(P<0.05).For LD muscle,m RNA expressions of type I and IIa MyHC in group DE3150 were higher than other treatments(P<0.01).The LD muscle in DE3150 expressed higher PPARd than in other groups(P<0.01).Pigs in DE3100 expressed higher FOX1 than in DE3200 and DE3250(P<0.05).Sterol-regulatory element binding proteins(SREBPa)mRNA expression decreased linearly when dietary energy level increased in BF muscle(P<0.01).In conclusion,a200 kcal/kg decrease in digestible energy for 4 consecutive weeks did not affect growth performance of Xiangcun Black pigs.Furthermore,LD and BF muscle respond differently to dietary energy level,and meat quality was improved by the medium energy level during the finishing phase. | Can Yang Wenlong Wang Xiaowu Tang Ruilin Huang Fengna Li Wenxuan Su Yulong Yin Chaoyue Wen Jian Liu | 2022 | Animal Nutrition2022,,4: | 1 |
| 12 | Nonlinear electronic and ultrafast optical signatures in chemical vapor-deposited ultrathin PtS_(2) ribbons显示文摘The emerging two-dimensional(2D)platinum disulfide(PtS_(2))has driven increasing attentions due to its high electron mobility,good air-stability,and strong interlayer interaction which leads to a widely tunable electronic structure.However,a detailed study on its covalent-like layer-dependent properties remains infant.Herein,we demonstrate the successful production of ultrathin 1T-PtS_(2) ribbons with thickness centralized almost at monolayer 1L-4L and large domain size up to 210 μm on Au foils using chemical vapor deposition(CVD)technique,which enables macro-and microscopic study of its extraordinary layer-dependent features with precise control of the number of layers.Using electron energy loss spectroscopy(EELS)and optical pump-probe spectroscopy(OPPS),we reveal that both the electron and ultrafast optical absorption signals of the as-grown 2D PtS_(2) show strong nonlinear layer-dependent responses which manifest discriminated transition in 1L-4L PtS_(2) ribbons.The layer-dependent nonlinear response of 2D PtS_(2) can be well interpreted in the frame of calculated electron and phonon structures.These achievements offer a platform for successfully fabricating large-sized ultrathin 2D PtS_(2) and facilitating our knowledge about its electronic and optoelectronic properties. | Shaolong Jiang Jin Yang Liang Zhu Jiafeng Xie Weiteng Guo Erding Zhao Chaoyu Chen Tianwu Wang Fuhai Su Yanfeng Zhang Junhao Lin | 2022 | Nano Research2022,15,5: | 1 |

| 16 | Chronic pulmonary bacterial infection facilitates breast cancer lung metastasis by recruiting tumor-promoting MHCII^(hi) neutrophils显示文摘Breast cancer can metastasize to various organs,including the lungs.The immune microenvironment of the organs to be metastasized plays a crucial role in the metastasis of breast cancer.Infection with pathogens such as viruses and bacteria can alter the immune status of the lung.However,the effect of chronic inflammation caused by bacteria on the formation of a premetastatic niche within the lung is unclear,and the contribution of specific immune mediators to tumor metastasis also remains largely undetermined.Here,we used a mouse model revealing that chronic pulmonary bacterial infection augmented breast cancer lung metastasis by recruiting a distinct subtype of tumor-infiltrating MHCII^(hi) neutrophils into the lung,which exhibit cancer-promoting properties.Functionally,MHCII^(hi) neutrophils enhanced the lung metastasis of breast cancer in a cell-intrinsic manner.Furthermore,we identified CCL2 from lung tissues as an important environmental signal to recruit and maintain MHCII^(hi) neutrophils.Our findings clearly link bacterial-immune crosstalk to breast cancer lung metastasis and define MHCII^(hi) neutrophils as the principal mediator between chronic infection and tumor metastasis. | Teng Ma Yu Tang Taolin Wang Yang Yang Yige Zhang Ruihuan Wang Yongxin Zhang Yi Li Mingbo Wu Miao Tang Xueli Hu Chaoyu Zou Yuan Ren Huan Liu Qianhua Zhang Heyue Li Min Wu Jing Li Xikun Zhou | 2023 | Signal Transduction and Targeted Therapy2023,8,9: | 0 |
| 17 | Using silk-derived magnetic carbon nanocomposites as highly efficient Nanozymes and electromagnetic absorbing agents显示文摘Functional carbon nanomaterials have become the stars of many active research fields,such as electronics,energy,catalysis,imaging,sensing and biomedicine.Herein,a facile and one-pot strategy for generating ferromagnetic nanoparticles loaded on N-doped carbon nanosheets(Fe-N-CNS)is presented by salt-assisted high-temperature carbonization of natural silk proteins.Due to their graphitic structures,N-doping and ferromagnetic nanoparticles(FeN_(x),FeO_(y),FeC_(z)),the silk-derived Fe-N-CNS can act as excellent mimics of both peroxidase and oxidase.Benefiting from the combined character of the graphene-like structures and enzyme-like activities,Fe-N-CNS can be further applied to highly efficient dye removal via synergistic adsorption and degradation.Meanwhile,the as-prepared Fe-N-CNS with intrinsic magnetism and electrical conductivity can also serve as an efficient electromagnetic wave absorption agent.The broadest effective absorption bandwidth(EAB)of as-obtained absorbing material yields a 6.73 GHz with 1 mm thickness,with a maximum reflection loss of-37.33 dB(11.41 GHz).The EAB can cover2~18 GHz with a tunable absorber thickness from 1.0 mm to 5.0 mm.Collectively,Fe-N-CNS,as a dualfunctional material,can tackle the aggravating environmental pollution issues of both dyes and electromagnetic waves. | Hao Wang Xianhui Zhang Yonghua Tang Weifeng Rong Jiachen Zhao Chaoyu Fan Zhisen Zhang Zhijun Sun Yun Yang Youhui Lin | 2023 | Chinese Chemical Letters2023,34,9: | 0 |
| 18 | Light-driven soft actuator based on graphene and WSe2 nanosheets composite for multimodal motion and remote manipulation显示文摘Remote controlled soft actuators have attracted ever-increasing interest in industrial,medical,robotics,and engineering fields.Soft actuators are charming than normal tools in executing dedicate tasks due to small volume and flexible body they have.However,it remains a challenge to design soft actuator that can adapt to multi-environments under remote stimuli with promising nano materials.Herein,we have developed a kind of near-infrared laser driven soft actuators with multi locomotive modes based on WSe2 and graphene nanosheets heterojunction.Different locomotion modes are driven by photothermal effect induced deformation to adapt to different working conditions.Moreover,the specially designed gripper driven by pulsed laser can lift a heavy load which is four times of its weight.This work broadens the choice of advanced nanomaterials for photothermal conversion of soft actuators.It is promising to realize applications including photothermal therapy and complex environment detection through the combination of the intelligent robot design and optical fiber system. | Zewen Su Yingjie Zhao Youqiang Huang Chaoyue Xu Xiaolei Yang Binrui Wang Beibei Xu Shiqing Xu Gongxun Bai | 2023 | Nano Research2023,16,1: | 0 |
| 19 | Hybrid piezo/triboelectric nanogenerator for stray magnetic energy harvesting and self‐powered sensing applications显示文摘Stray magnetic fields with a fixed frequency of 50/60 Hz are ubiquitous in buildings,factories,and power system equipment.Researchers are increasingly focusing on har-vesting electrical energy from stray magnetic fields to provide sustainable energy for the Internet of Things(IoT)devices.Magneto‐mechano‐electric energy conversion is the most efficient way to convert low‐frequency stray magnetic fields into electricity.In this study,we proposed a hybrid piezo/triboelectric nanogenerator(HP/TENG)on the basis of a cantilever beam to use stray magnetic fields from the surrounding environment.The hybrid nanogenerator provided high output voltage/current and power of∼176 V/375μA and 4.7 mW(matched impedance of 20 kΩ)in a magnetic field environment of 4 Oe.The device provided a stable 3.6 V direct current output by incorporating energy management circuitry to sustainably drive power to commercial wireless temperature/humidity sensors.The HP/TENG has a significant application potential in IoT,which can use stray magnetic energy and a power wireless sensor system. | Aijun Yang Chaoyu Wang Jing Ma Chengyu Fan Pinlei Lv Yuchen Bai Yiming Rong Xiaohua Wang Huan Yuan Mingzhe Rong | 2021 | High Voltage2021,6,6: | 0 |
| 20 | Regulating the coordination environment of Ru single-atom catalysts and unravelling the reaction path of acetylene hydrochlorination显示文摘In this work,DFT calculations were used firstly to simulate the nitrogen coordinated metal single-atom catalysts(M-N_(x)SACs,M=Hg,Cu,Au,and Ru) to predict their catalytic activities in acetylene hydrochlorination.The DFT results showed that Ru-N_(x)SACs had the best catalytic performance among the four catalysts,and Ru-N_(x)SACs could effectively inhibit the reduction of ruthenium cation.To verify the DFT results,Ru-N_(x)SACs were fabricated by pyrolyzing MOFs in-situ spatially confined metal precursors.The N coordination environment could be controlled by changing the pyrolysis temperature.Catalytic performance tests indicated that low N coordination number(Ru-N_(2),Ru-N_(3))exhibited excellent catalytic activity and stability compared to RuCl_(3)catalyst.DFT calculations further revealed that Ru-N_(2)and Ru-N_(3)had a tendency to activate HCl at the first step of reaction,whereas Ru-N4tended to activate C_(2)H_(2).These findings will serve as a reference for the design and control of metal active sites. | Yang Yang Chaoyue Zhao Xianliang Qiao Qingxin Guan Wei Li | 2023 | Green Energy & Environment2023,8,4: | 0 |
