| 1 | Functional Characterization of the Promoter and Second Intron of CUM1 During Flower Development in Cucumber(Cucumis sativus L.)显示文摘The characterization of flower specific promoter is critical during flower development by cucumber transformation technology.AGAMOUS(AG)is an organ identity gene that is required for carpel and stamen development in Arabidopsis.The promoter and second intron of AG contain multiple regulatory elements that confer proper spatial and temporal expression.Cucumber is an important vegetable with unisexual flowers.Cucumber MADS-box 1(CUM1)is the AG homolog in cucumber,belonging to the eu AG lineage along with AG.In situ hybridization showed that CUM1 was specifically expressed in the stamens and carpels of cucumber.GUS staining indicated that the second intron of CUM1 confers stamen-specific expression,while the promoter of CUM1 drives both stamen-and carpel-specific expression during the early stages of flower development,but is restricted to carpel-and connectivum-specific expression during the late stages of flower development.Furthermore,a yeast one-hybrid assay demonstrated that two auxin response factors(Cs ARF13 and Cs ARF17)had bound directly to the second intron of CUM1.Our data suggest that different regulatory circuits operate in AG homologs in plant species with distinct sex types. | GU Ran LIU Xiaofeng ZHAO Wensheng YAN Shuangshuang SUN Linhan WU Binning ZHANG Xiaolan | 2018 | Horticultural Plant Journal2018，4，3： | 9 |
| 2 | Experiment and simulation on the pyrite removal from the recirculating load of pulverizer with a dilute phase gas-solid fluidized bed显示文摘In order to reduce the energy consumption and subsequent air pollution of coal-fired power station, based on the analysis to size and density distribution of particles from the recirculating load of the classifier of pulverizer, the separation experiment on sampling material from power plant with a dilute phase fluidized bed to remove pyrite and other minerals and numerical simulation on the separation process were done. The results show that the minimum fluidization velocity is 1.62 cm/s. Pyrite and other minerals in the material are separated. Ash of the upper and bottom layer material account for 33.34% and 73.42% respectively and sulfur content occupy 1.12% and 8.96% respectively. Scanning electron microscopy and spectroscopy tests show that sulfur in the bottom material exist in the form of pyrite. Numerical simulation on the flow field form of the dilute phase separation bed with gas-solid two phase and particle motion verifies the experimental results. | Wang Shuai He Yaqun He Jingfeng Ge Linhan Liu Qing | 2013 | International Journal of Mining Science and Technology2013，23，2： | 6 |
| 3 | Pathogenesis of allergic diseases and implications for therapeutic interventions显示文摘Allergic diseases such as allergic rhinitis (AR), allergic asthma (AAS), atopic dermatitis (AD), food allergy (FA), and eczema aresystemic diseases caused by an impaired immune system. Accompanied by high recurrence rates, the steadily rising incidence ratesof these diseases are attracting increasing attention. The pathogenesis of allergic diseases is complex and involves many factors,including maternal-fetal environment, living environment, genetics, epigenetics, and the body’s immune status. The pathogenesisof allergic diseases exhibits a marked heterogeneity, with phenotype and endotype defining visible features and associatedmolecular mechanisms, respectively. With the rapid development of immunology, molecular biology, and biotechnology, manynew biological drugs have been designed for the treatment of allergic diseases, including anti-immunoglobulin E (IgE), antiinterleukin(IL)-5, and anti-thymic stromal lymphopoietin (TSLP)/IL-4, to control symptoms. For doctors and scientists, it is becomingmore and more important to understand the influencing factors, pathogenesis, and treatment progress of allergic diseases. Thisreview aimed to assess the epidemiology, pathogenesis, and therapeutic interventions of allergic diseases, including AR, AAS, AD,and FA. We hope to help doctors and scientists understand allergic diseases systematically. | Ji Wang Yumei Zhou Honglei Zhang Linhan Hu Juntong Liu Lei Wang Tianyi Wang Haiyun Zhang Linpeng Cong Qi Wang | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 3 |
| 4 | Subsurface reconstruction and saturation of surface bonds显示文摘Surface reconstructions and stabilization mechanisms have been great challenges for insulators. Based on accurate determination of the long-sought atomic structure of the spinel(1 1 1) surface, here we show that the surface is stabilized by an unconventional mechanism. In general, solid surfaces have unsaturated chemical bonds and are prone to atomic reconstruction to saturate them. The spinel(1 1 1) surface,however, has the surface bonds fully saturated, while the unsaturated bonds remain only in the subsurface. It undergoes a reconstruction that keeps the topmost atomic layer unchanged, but has the subsurface atoms completely rearranged. Such a reconstruction results in a perfect compensation of the surface polarity and a large reduction in the surface energy. This work provides surprising insights into the surface stability and physical and chemical behaviors of complex oxides and insulators. | Linhan Liu Yonghao Sun Zhiying Cheng Jing Zhu Rong Yu | 2018 | Science Bulletin2018，63，23： | 2 |
| 5 | Opto-thermoelectric pulling of light-absorbing particles显示文摘Optomechanics arises from the photon momentum and its exchange with low-dimensional objects.It is well known that optical radiation exerts pressure on objects,pushing them along the light path.However,optical pulling of an object against the light path is still a counter-intuitive phenomenon.Herein,we present a general concept of optical pulling-opto-thermoelectric pulling(OTEP)—where the optical heating of a light-absorbing particle using a simple plane wave can pull the particle itself against the light path.This irradiation orientation-directed pulling force imparts self-restoring behaviour to the particles,and three-dimensional(3D)trapping of single particles is achieved at an extremely low optical intensity of 10^(−2)mWμm^(−2).Moreover,the OTEP force can overcome the short trapping range of conventional optical tweezers and optically drive the particle flow up to a macroscopic distance.The concept of selfinduced opto-thermomechanical coupling is paving the way towards freeform optofluidic technology and lab-on-achip devices. | Linhan Lin Pavana Siddhartha Kollipara Abhay Kotnala Taizhi Jiang Yaoran Liu Xiaolei Peng Brian A.Korgel Yuebing Zheng | 2020 | Light(Science & Applications)2020，9，1： | 1 |
| 6 | Photoswitchable quantum electrodynamics in a hybrid plasmonic quantum emitter显示文摘The design and preparation of quantum states free from environmen-tal decohering effects is critically important for the development of on-chip quantum systems with robustness.One promising strategy is to harness quantum state superposition to construct decoherence-free subspace(DFS),which is termed dark state.Typically,the exci-tation of dark states relies on anti-phase-matching on two qubits and the inter-qubit distance is of wavelength scale,which limits the de-velopment of compact quantum chips.In the current work,a hybrid plasmonic quantum emitter was proposed,which was composed of strongly correlated quantum emitters intermediated by a plasmonic nanocavity.Through turning the plasmonic loss from drawback into advantage,the anti-phase-matching rule was broken by rapidly de-caying the superposed bright state and preparing a sub-100 nm dark state with decay rate reduced by 3 orders of magnitudes.More inter-estingly,the dark state could be optically switched to a single-photon emitter with enhanced brightness through photon-blockade,with the quantum second order correlation function at zero delay showing a wide range of tunability down to 0.02. | Yuan Liu Hongwei Zhou Peng Xue Linhan Lin Hong-Bo Sun | 2023 | Chip2023，2，3： | 0 |
| 7 | Opto-thermoelectric microswimmers显示文摘Inspired by the“run-and-tumble”behaviours of Escherichia coli(E.coli)cells,we develop opto-thermoelectric microswimmers.The microswimmers are based on dielectric-Au Janus particles driven by a self-sustained electrical field that arises from the asymmetric optothermal response of the particles.Upon illumination by a defocused laser beam,the Janus particles exhibit an optically generated temperature gradient along the particle surfaces,leading to an opto-thermoelectrical field that propels the particles.We further discover that the swimming direction is determined by the particle orientation.To enable navigation of the swimmers,we propose a new optomechanical approach to drive the in-plane rotation of Janus particles under a temperature-gradient-induced electrical field using a focused laser beam.Timing the rotation laser beam allows us to position the particles at any desired orientation and thus to actively control the swimming direction with high efficiency.By incorporating dark-field optical imaging and a feedback control algorithm,we achieve automated propelling and navigation of the microswimmers.Our optothermoelectric microswimmers could find applications in the study of opto-thermoelectrical coupling in dynamic colloidal systems,active matter,biomedical sensing,and targeted drug delivery. | Xiaolei Peng Zhihan Chen Pavana Siddhartha Kollipara Yaoran Liu Jie Fang Linhan Lin Yuebing Zheng | 2020 | Light(Science & Applications)2020，9，1： | 0 |
