2Design and field tests of a deck-extension bridge with small box girder显示文摘A jointless bridge could fundamentally eliminate vulnerable deck joints, thereby meeting the need for sustainable development of bridges, especially for an expressway with highspeed traffic. In this paper, one jointless bridge(deck-extension bridge) with a small box girder in an expressway was chosen as a case study to examine the structural design,construction and field test. The field tests of the bridge indicated that the designed and constructed structures can satisfy the requirement for service performance of the deckextension bridge. Some key technologies, such as the position of longitudinal reinforcements in the superstructure-approach slab connections and the arrangement of the sliding material layers, were introduced. The longitudinal thermal movement of the superstructure in the deck-extension bridge with a small box girder could be predicted accurately by using the average temperature of the cross section of a small box girder. The finite element model, built by using the MIDAS program, was used to analyze the temperature distribution on the cross section of a small box girder, the accuracy of which could be verified by comparing with the measured values. The maximum longitudinal thermal movement of the superstructure in deck-extension bridges with a small box girder under historically extreme temperature conditions was predicted.Junqing Xue Bruno Briseghella Jianhui Lin Fuyun Huang Baochun Chen 2018Journal of Traffic and Transportation Engineering(English Edition)2018,5,6:7
3Simulation of electro-slag re-melting process of 120t large ingot for nuclear power station and its application显示文摘Further research on metallic materials for the super critical rotator and the main pipe line of a nuclear power station is very important for developing the nuclear power industry. In this study, the mathematical model for 120 t large ingot was established, and the computer program ESR3D was developed to simulate the whole electro-slag re-melting (ESR) process. This includes the electrode melting, metallic droplet falling, metal pool forming, metal pool and slag pool rising and moving, installation of top crystallizer, ingot solidifying, etc. The simulated average melting rate of the electrode was in good agreement with that in practical production. The optimized parameters were used to produce 80-120 t large ingots, and the quality of the ingots satisfied the specifications of nuclear power and the super critical generating unit.Liu Xihai Wang Junqing Jia Weiguo Gao Jianjun Zhao Lin Tang Zuobin 2011China Foundry2011,8,4:6
4Metal-organic frameworks nanoswitch:Toward photo-controllable endo/lysosomal rupture and release for enhanced cancer RNA interference显示文摘Endo/lysosomal escape and gene release are two critical bottlenecks in gene delivery.Herein,a novel photo-controllable metal-organic frameworks(MOFs)nanoswitch is rationally designed for enhancing small interfering RNA(siRNA)delivery.One single laser triggers the“off-to-on”switching of MOFs nanocomplexes,inducing significant siRNA release accompanied by rapid MOFs dissociation into protonatable 2-methylimidazalo and osmotic rupturing Zn2+ions,which cooperatively contribute to remarkable endo/lysosomal rupture(∼90%).The simultaneous endo/lysosomal rupture and release enable a high spatio-temporal control on RNA interference for effective cancer therapy.Notably,the“off-to-on”switching also activates fluorescence recovery for real-time monitoring siRNA delivery.The nanoswitch could easily be extended to deliver other therapeutic agents(e.g.,DNA,protein,anticancer drug)for overcoming endo/lysosomal entrapment.Gan Lin Yang Zhang Long Zhang Junqing Wang Ye Tian Wen Cai Shangui Tang Chengchao Chu JiaJing Zhou Peng Mi Xiaoyuan Chen Gang Liu 2020Nano Research2020,13,1:5
5Intrinsically Stretchable Organic-Tribotronic-Transistor for Tactile Sensing显示文摘Stretchable electronics are of great significance for the development of the next-generation smart interactive systems.Here,we propose an intrinsically stretchable organic tribotronic transistor(SOTT)without a top gate electrode,which is composed of a stretchable substrate,silver nanowire electrodes,semiconductor blends,and a nonpolar elastomer dielectric.The drain-source current of the SOTT can be modulated by external contact electrification with the dielectric layer.Under 0-50%stretching both parallel and perpendicular to the channel directions,the SOTT retains great output performance.After being stretched to 50%for thousands of cycles,the SOTT can survive with excellent stability.Moreover,the SOTT can be conformably attached to the human hand,which can be used for tactile signal perception in human-machine interaction and for controlling smart home devices and robots.This work has realized a stretchable tribotronic transistor as the tactile sensor for smart interaction,which has extended the application of tribotronics in the human-machine interface,wearable electronics,and robotics.Junqing Zhao Tianzhao Bu Xiaohan Zhang Yaokun Pang Wenjian Li Zhi Zhang Guoxu Liu Zhong Lin Wang Chi Zhang 2020Research2020,,1:4
6Electromagnetic and microwave absorption properties of Er-Ho-Fe alloys显示文摘The Er_xHo_(2-x)Fe_(17)(x = 0.0, 0.1,0.2, 0.3, 0.4) powders were prepared by arc melting and high energy ball milling method. The influence of the Er substitution on phase structure, morphology, saturation magnetization,electromagnetic parameters was investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM), vibrating sample magnetometer(VSM) and vector network analyzer(VNA),respectively. The results show that the saturation magnetization increases and the average particle size increases with the increase of Er content. The minimum absorption peak frequency shifts towards a lower frequency region with the increase of Er content. The Er_(0.3)Ho_(1.7)Fe_(17) powder can achieve the minimum RL of-24.07 dB at 6.96 GHz with a thickness of 2.0 mm and the minimum RL is less than-20 dB at the thickness range from 2.0 to 3.0 mm. The minimum RL of Er_(0.3)Ho_(1.7)Fe_(17) is-37.26 dB at5.68 GHz and the frequency bandwidth of R<-10 dB reaches about 1.2 GHz with a thickness of 2.4 mm.And the microwave absorbing properties of the composite with different weight ratios of Er_(0.3)Ho_(1.7)Fe_(17)/graphene were researched. The microwave absorbing peaks of the composite shift to lower frequency with the increase of graphene content. The values of the minimum RL of Er_(0.3)Ho_(1.7)Fe_(17)/graphene are close to-10 dB with absorbing coating thicknesses increased.Jialiang Luo Shunkang Pan Lichun Cheng Peihao Lin Yu He Junqing Chang 2018Journal of Rare Earths2018,36,7:3

8Clinicopathologic Characteristics and Surgical Outcome of Gastric Cancer in Patients Younger than 36 Years of Age显示文摘OBJECTIVE This study was designed to determine theclinicopathologic features of young patients who underwentgastrectomy for gastric cancer and to improve the clinicalmanagement of this disease.METHODS From 1981 to 2000,among 1,830 gastric cancerpatients were admitted in our hospital for surgical treatment,66of them were<36 years of age.The clinicopathologic data of theseyoung patients were collected and reviewed.RESULTS The male:female ratio was 1.2:1.Most tumors werelocated in the lower third of the stomach(63.1%).The overall5-year survival rate of 66 cases was 28.7%.The 5-year survivalrates in the patients with early stages and with advanced stages ofgastric carcinoma were 77.8%(7/9)and 21.1%(12/57),respectively.Unfavorable prognostic factors associated with poor 5-yearsurvival included the degree of the invasion in the gastric wall(P<0.05),and curability of resection(non-curative vs.curative;P<0.05).CONCLUSION Gastric cancer in young adults tends to be moreadvanced presentation when diagnosed.However,young patientswith early gastric cancer can tolerate radical treatments well.Itis important to promptly make a precise diagnosis for gastriccarcinoma in young patients and to treat it in early stage.Dapeng Lin Ping Lu Caigang Liu Huimian Xu ShubaoWang Junqing Chen 2009Clinical oncology and cancer resexreh2009,6,4:1
9Upper Paleozoic total petroleum system and geological model of natural gas enrichment in Ordos Basin, NW China显示文摘Based on the analysis of Upper Paleozoic source rocks, source-reservoir-caprock assemblage, and gas accumulation characteristics in the Ordos Basin, the gas accumulation geological model of total petroleum system is determined. Then, taking the Carboniferous Benxi Formation and the Permian Taiyuan Formation and Shanxi Formation as examples, the main controlling factors of gas accumulation and enrichment are discussed, and the gas enrichment models of total petroleum system are established. The results show that the source rocks, faults and tight reservoirs and their mutual coupling relations control the distribution and enrichment of gas. Specifically, the distribution and hydrocarbon generation capacity of source rocks control the enrichment degree and distribution range of retained shale gas and tight gas in the source. The coupling between the hydrocarbon generation capacity of source rocks and the physical properties of tight reservoirs controls the distribution and sweet spot development of near-source tight gas in the basin center. The far-source tight gas in the basin margin is mainly controlled by the distribution of faults, and the distribution of inner-source, near-source and far-source gas is adjusted and reformed by faults. Generally, the Upper Paleozoic gas in the Ordos Basin is recognized in four enrichment models: inner-source coalbed gas and shale gas, inner-source tight sandstone gas, near-source tight gas, and far-source fault-transported gas. In the Ordos Basin, inner-source tight gas and near-source tight gas are the current focuses of exploration, and inner-source coalbed gas and shale gas and far-source gas will be important potential targets in the future.JIANG Fujie JIA Chengzao PANG Xiongqi JIANG Lin ZHANG Chunlin MA Xingzhi QI Zhenguo CHEN Junqing PANG Hong HU Tao CHEN Dongxia 2023Petroleum Exploration and Development2023,50,2:1

12An FPS-ZM1-encapsulated zeolitic imidazolate framework as a dual proangiogenic drug delivery system for diabetic wound healing显示文摘Inhibitors that target diabetes pathology-related signaling pathways have great therapeutic potential for diabetic wound healing.Metal–organic frameworks(MOFs)are increasingly popular drug delivery systems that have high loading capacity and can release their intrinsic metal ions to act as bioactive agents.In light of this,a receptor for advanced glycation end products(RAGE)inhibitor,4-chloro-N-cyclohexyl-N-(phenylmethyl)-benzamide(FPS-ZM1),was loaded into a cobalt(Co)-based MOF(zeolitic imidazolate framework-67,ZIF-67)to fabricate FPS-ZM1 encapsulated ZIF-67(FZ@ZIF-67)nanoparticles(NPs).As a result,FZ@ZIF-67 NPs could dually deliver Co ions and FPS-ZM1 in a controlled manner for over 14 days.Our in vitro study showed that FZ@ZIF-67 NPs not only enhanced angiogenesis by delivering Co ions but also released FPS-ZM1 to promote M2 macrophage polarization and attenuated high glucose(HG)-and/or inflammation-induced impairment of angiogenesis through RAGE inhibition.Moreover,in an in vivo study,FZ@ZIF-67 NPs markedly improved re-epithelialization,collagen deposition,neovascularization,and relieved inflammation in diabetic wounds in rats.This study not only provides a low-cost,effective,and synergistic proangiogenic bioactive agent but also demonstrates that targeting diabetes-related pathological signaling pathways is necessary to ameliorate vascularization impairment during diabetic wound healing.Yi Sun Bingbo Bao Yu Zhu Junjie Shen Xuanzhe Liu Tao Gao Junqing Lin Tengli Huang Jia Xu Yimin Chai Xianyou Zheng 2022Nano Research2022,15,6:0
13BI-GreenNet:Learning Green’s Functions by Boundary Integral Network显示文摘Green’s function plays a significant role in both theoretical analysis and numerical computing of partial differential equations(PDEs).However,in most cases,Green’s function is difficult to compute.The troubles arise in the following threefold.Firstly,compared with the original PDE,the dimension of Green’s function is doubled,making it impossible to be handled by traditional mesh-based methods.Secondly,Green’s function usually contains singularities which increase in the difficulty to get a good approximation.Lastly,the computational domain may be very complex or even unbounded.To override these problems,we develop a new framework for computing Green’s function leveraging the fundamental solution,boundary integral method and neural networkswith reasonably high accuracy in this paper.We focus on Green’s function of Poisson and Helmholtz equations in bounded domains,unbounded domains.We also consider Poisson equation and Helmholtz equations in domains with interfaces.Extensive numerical experiments illustrate the efficiency and accuracy of our method for solving Green’s function.In addition,Green’s function provides the operator from the source term and boundary condition to thePDEsolution.We applyGreen’s function to solve PDEs with different sources,and obtain reasonably high-precision solutions,which shows the good generalization ability of our method.However,the requirements for explicit fundamental solutions to remove the singularity of Green’s function hinder the application of our method in more complex PDEs,such as variable coefficient equations,which will be investigated in our future work.Guochang Lin Fukai Chen Pipi Hu Xiang Chen Junqing Chen Jun Wang Zuoqiang Shi 2023Communications in Mathematics and Statistics2023,11,1:0
14Tumor Microenvironment-Specific Chemical Internalization for Enhanced Gene Therapy of Metastatic Breast Cancer显示文摘Benefiting from treating diseases at the genetic level,gene therapy has been considered a new revolution in the biomedical field.However,the extracellular and intracellular barriers during gene transport such as enzymatic degradation and endo-/lysosomal sequestration significantly compromise the therapeutic efficacy.Though photochemical internalization(PCI)has emerged as a promising approach for causing endo-/lysosomal leakage with translocation of the internalized molecules into the cytosol,its effect is still unsatisfactory due to the insufficient light penetration depth.Here,we develop tumor microenvironment-specific enhanced gene delivery by means of ROS generated from the in situ cascaded catalytic reactions in tumors involving GOx-mediated redox reaction and Mn2+-mediated Fenton-like reaction.The efficient enzymatic protection and successful endo-/lysosomal escape of cargo gene complexes have been demonstrated.Moreover,anti-Twist siRNA-loaded G@MMSNs-P exhibit tumor-specific biodegradation,excellent T1-weighted MR imaging,and significant inhibitory effects against breast cancer growth and pulmonary metastasis.Yun Zhou Mian Yu Changjun Tie Yang Deng Junqing Wang Yunfei Yi Fan Zhang Chenyi Huang Hairong Zheng Lin Mei Meiying Wu 2021Research2021,,1:0
