| 1 | Ultrahigh-Q silicon racetrack resonators显示文摘An ultrahigh-Q silicon racetrack resonator is proposed and demonstrated with uniform multimode silicon photonic waveguides.It consists of two multimode straight waveguides connected by two multimode waveguide bends(MWBs).In particular,the MWBs are based on modified Euler curves,and a bent directional coupler is used to achieve the selective mode coupling for the fundamental mode and not exciting the higher-order mode in the racetrack.In this way,the fundamental mode is excited and propagates in the multimode racetrack resonator with ultralow loss and low intermode coupling.Meanwhile,it helps achieve a compact 180°bend to make a compact resonator with a maximized free spectral range(FSR).In this paper,for the chosen 1.6μm wide silicon photonic waveguide,the effective radius Reffof the designed 180°bend is as small as 29μm.The corresponding FSR is about 0.9 nm when choosing 260μm long straight waveguides in the racetrack.The present high-Q resonator is realized with a simple standard single-etching process provided by a multiproject wafer foundry.The fabricated device,which has a measured intrinsic Q-factor as high as 2.3×10~6,is the smallest silicon resonator with a>106Q-factor. | LONG ZHANG LANLAN JIE MING ZHANG YI WANG YIWEI XIE YAOCHENG SHI DAOXIN DAI | 2020 | Photonics Research2020,8,5: | 7 |

| 4 | High-resolution characterization of hexagonal boron nitride coatings exposed to aqueous and air oxidative environments显示文摘六角形的硼氮化物(h-BN ) 被相信由于它的绝缘的性质比 graphene 把更好的钝化提供给金属性的表面,它便于堵住电子的流动,从而阻止流电的反应的出现。不过,当 h-BN-protected 材料暴露于水的环境时,这不能是盒子。在这个工作,我们分析了暴露于 H 2 O 2 和大气的条件。当暴露了到 H 2 O 2 。多层的 h-BN 提供了保护的好度。单层 h-BN 被发现也在空气气氛无效。甚至 10-15 层厚的 h-BN 栈不能完全在考虑下面保护金属的表面。由联合钻电子光谱学和第二等的离子团 spectrometry 技术,我们观察到氧能通过 h-BN 栈的谷物边界扩散到达金属性的底层。因为这个过程的散开的性质,一旦一个浸透的状态被到达,幸好,氧化区域没与时间增加。这成为多层(不单层) h-BN 一个合适的长期的氧化障碍。氧渗入不能被 X 光检查光电子光谱学观察。这种技术不能估计材料的更深的层的化学作文。因此,以前的报告,依靠了 XPS 分析 h-BN 和 graphene 的使钝化的性质,可能忽略了一些重要表面下的现象。在这研究获得的结果在水的媒介和暴露于空气环境的 h-BN-coated 金属的降级动力学提供新卓见进单音、多层的 h-BN 的使钝化的性质。 | Lanlan Jiang Na Xiao Bingru Wang Enric Grustan-Gutierrez Xu Jing Petr Babor Miroslav Kogbal Guangyuan Lu Tianru Wu Haomin Wang Fei Hui Yuanyuan Shi Bo Song Xiaoming Xie Mario Lanza | 2017 | Nano Research2017,10,6: | 2 |

| 8 | Enhanced intermolecular interactions to improve twisted polymer photovoltaic performance显示文摘In polymer solar cells(PSCs), twisted polymer donors usually have low photovoltaic efficiencies due to their poor photoactive layer morphologies. Herein, we successfully improved twisted polymer(PBDT-3T) photovoltaic efficiency by employing C=O groups(PBDT-3TCO) to enhance intermolecular interactions. The maximum power conversion efficiency(PCE) of PBDT-3T is only 1.05%, while the PCE of PBDT-3TCO reaches 11.77% in non-fullerene(NF) PSCs. Both polymers-based PSCs show very similar open-circuit voltages but remarkable differences in their short-circuit currents and fill factors. The single crystals of both functionalized terthiophenes with methyl substituents demonstrate that the terthiophene with C=O units changes molecular pattern by forming intra/inter molecular S???O and O???H interactions but its molecular planarity does not significantly improve.Our comparative studies show that PBDT-3TCO with C=O units possesses a strong aggregation property and optimal photoactive layer morphology in NF PSCs. This study provides important insight into the design of high-performance twisted polymer donors for NF PSCs. | Cunbin An Jingming Xin Lanlan Shi Wei Ma Jianqi Zhang Huifeng Yao Sunsun Li Jianhui Hou | 2019 | Science China Chemistry2019,62,3: | 1 |
| 9 | Identify Landslide Precursors from Time Series InSAR Results显示文摘Landslides cause huge human and economic losses globally.Detecting landslide precursors is crucial for disaster prevention.The small baseline subset interferometric synthetic-aperture radar(SBAS-InSAR)has been a popular method for detecting landslide precursors.However,non-monotonic displacements in SBAS-InSAR results are pervasive,making it challenging to single out true landslide signals.By exploiting time series displacements derived by SBAS-InSAR,we proposed a method to identify moving landslides.The method calculates two indices(global/local change index)to rank monotonicity of the time series from the derived displacements.Using two thresholds of the proposed indices,more than 96%of background noises in displacement results can be removed.We also found that landslides on the east and west slopes are easier to detect than other slope aspects for the Sentinel-1 images.By repressing background noises,this method can serve as a convenient tool to detect landslide precursors in mountainous areas. | Meng Liu Wentao Yang Yuting Yang Lanlan Guo Peijun Shi | 2023 | International Journal of Disaster Risk Science2023,14,6: | 0 |
| 10 | High-entropy alloy catalysts:From bulk to nano toward highly efficient carbon and nitrogen catalysis显示文摘High-entropy alloys(HEAs)have attracted widespread attention as both structural and functional materials owing to their huge multielement composition space and unique high-entropy mixing structure.Recently,emerging HEAs,either in nano or highly porous bulk forms,are developed and utilized for various catalytic and clean energy applications with superior activity and remarkable durability.Being catalysts,HEAs possess some unique advantages,including(1)a multielement composition space for the discovery of new catalysts and fine-tuning of surface adsorption(i.e.,activity and selectivity),(2)diverse active sites derived from the random multielement mixing that are especially suitable for multistep catalysis,and(3)a high-entropy stabilized structure that improves the structural durability in harsh catalytic environments.Benefited from these inherent advantages,HEA catalysts have demonstrated superior catalytic performances and are promising for complex carbon(C)and nitrogen(N)cycle reactions featuring multistep reaction pathways and many different intermediates.However,the design,synthesis,characterization,and understanding of HEA catalysts for C-and N-involved reactions are extremely challenging because of both complex high-entropy materials and complex reactions.In this review,we present the recent development of HEA catalysts,particularly on their innovative and extensive syntheses,advanced(in situ)characterizations,and applications in complex C and N looping reactions,aiming to provide a focused view on how to utilize intrinsically complex catalysts for these important and complex reactions.In the end,remaining challenges and future directions are proposed to guide the development and application of HEA catalysts for highly efficient energy storage and chemical conversion toward carbon neutrality. | Lanlan Yu Kaizhu Zeng Chenghang Li Xiaorong Lin Hanwen Liu Wenhui Shi Hua-Jun Qiu Yifei Yuan Yonggang Yao | 2022 | Carbon Energy2022,4,5: | 0 |
| 11 | Game Theoretic Simulation on the Mimicry Honeypot显示文摘A mimicry honeypot framework based on game theory is presented in our work, which can calculate the equilibrium strategy of the deceptive game using non-cooperative incomplete dynamic game theory, and make decisions for the mimicry framework to deploy the simple service, the honeypot and the fake honeypot. A mimicry prototype is implemented using NS2 platform, and simulation experiments are launched to validate the decision-making result and the deceptive performance of the mimicry honeypot. The empirical study shows that the mimicry honeypot framework based on game theory can be able to influence the equilibrium strategy results by dynamically changing the deployment vector of the mimicry system. It validates that the mimicry honeypot framework has better flexibility, activeness and fraudulence than the traditional honeypot. | SHI Leyi ZHAO Junnan JIANG Lanlan XING Wenjuan GONG Jian LIU Xin | 2016 | Wuhan University Journal of Natural Sciences2016,21,1: | 0 |
| 12 | Physical and Mechanical Properties of Catalpa bungei Clones and Estimation of the Properties by Near-Infrared Spectroscopy显示文摘Air-dry density,modulus of rupture(MOR),modulus of elasticity(MOE),compressive strength parallel to grain,and hardness of Catalpa bungei clones were investigated in this study with feasibility of predicting these properties by near infrared(NIR)spectroscopy.The best candidate Luoqiu 3'has been selected from three clones based on wood physical and mechanical property indices.Lower values of wood physical and mechanical properties have been found in the corewood compared to the outerwood.There were significant positive correlations between the air-dry density and mechanical properties.Information from Cross section for air dry density,compressive strength parallel to grain,and hardness yielded prediction models with better effects,along with the best MOR and MOE modeling effects resulted from average sections'spectra collection.Multiplicative scatter correction(MSC)+Savitzky-Golay(S-G)smoothing method has been proved to be the most applicable way.In addition,the predictions from five point sampling method were slightly better than three point one.Overall,results suggest NIR spectroscopy was viable to predict the physical and mechanical properties of C bungei dones with methods developed in this study proved effective in preliminary screening. | Rui Wang Lanlan Shi Yurong Wang | 2022 | Journal of Renewable Materials2022,10,12: | 0 |
| 13 | Cancer-macrophage hybrid membrane-camouflaged photochlor for enhanced sonodynamic therapy against triple-negative breast cancer显示文摘Sonodynamic therapy(SDT)has aroused considerable momentum in cancer therapy due to its abilities of deep penetration,low toxicity,and noninvasion,while insufficient tumor accumulation of sonosensitizers is a major obstacle for SDT effect.Here,we developed a 4T1 cancer cell-macrophage hybrid membrane(HM)-camouflaged sonosensitizer nanoplatform by encapsulating photochlor(HPPH)-loaded albumin nanoparticles(PHNPs).The experimental results proved that the HM-coated biomimetic NPs(PHNPs@HM)could express the characteristic membrane proteins of both cancer cells and macrophages,remarkedly enhancing the effective targeting and endocytosis to 4T1 cells through homologous adhesion recognition and immune escaping.Meanwhile,as a novel sonosensitizer,HPPH could generate amount of reactive oxygen species(ROS)under ultrasound(US)irradiation and exhibit obvious SDT efficiency to inhibit 4T1 tumor growth through ROS-induced cell apoptosis.This study provides a novel and multifunctional biomimetic sonosensitizer system to enhance SDT efficiency. | Lishan Zhang Ting Yin Baozhen Zhang Chong Yan Chengyu Lu Lanlan Liu Ze Chen Hui Ran Qingxia Shi Hong Pan Aiqing Ma Lintao Cai | 2022 | Nano Research2022,15,5: | 0 |

| 15 | Selecting small molecule DNA aptamers with significant conformational changes for constructing transcriptional switches and biosensors显示文摘Small molecule aptamers discovered by traditional selection methods usually lack conformational changes upon target binding.This limits the use of aptamers as molecular probes for small molecule detection and regulatory elements of genetic circuits.Here,we report a new method called capture and in vitro transcription-systematic evolution of ligands by exponential enrichment(CIVT-SELEX)to select DNA aptamers that can not only bind to small molecule ligands but also undergo significant conformational changes.Through this method,we select a structure-switching aptamer of uridine-5′-diphosphate(UDP).Taking advantage of its conformational changes,we first construct a UDP-responsive transcriptional switch by inserting the aptamer in a genetic circuit and demonstrate that it can respond to the addition of UDP and regulate the transcription of downstream genes.We also build a UDP aptamer-based biosensor that can be used for active glycosyltransferase screening.We believe this method can provide a universal platform for selecting small molecule aptamers with conformational changes and expand the use of aptamers in small molecule detection and genetic regulation. | Shaobin Guo Jingjing Lin Lujie Lin Wen Xu Yan Guo Zipeng Xu Chunhua Lu Xianai Shi Lanlan Chen Huanghao Yang | 2023 | Science China Chemistry2023,66,5: | 0 |
| 16 | Gut microbiota and differential genes-maintained homeostasis is key to maintaining health of individuals with Yang-deficiency constitution显示文摘OBJECTIVE:Yang-deficiency constitution(YADC)is a common unbalanced constitution that predisposes individuals to certain diseases.However,not all people with YADC manifest develop diseases.This calls for delineation of the underlying molecular mechanisms.Previous studies suggested that the gut microbiota and gene differential expression should be considered.METHODS:In the present study,we compared profiles of gut microbiota between four healthy YADC individuals and those of five healthy balanced constitution(BC)counterparts,based on 16 S r RNA gene sequence analysis.Furthermore,YADC relevant genes identified by comparing 62 healthy YADC and 58 healthy BC individuals in total to perform intersection analysis,functional clustering and pathway enrichment analyses.RESULTS:The levels of harmful gut microbiota(Prevotellaceae,LDA score>4.0,P=0.0141)and beneficial gut microbiota(Ruminococcaceae,LDA score>4.0,P=0.0025,Faecalibacterium,LDA score>4.0,P=0.0484)were both elevated in healthy YADC individuals.Also,we found that the specific metabolic pathway with 2,6-Dichloro-p-hydroquinone 1,2-Dioxygenase(Pcp A)as the core in gut microbiota and the glutathione transferase activity has been enriched by YADC relevant genes in healthy YADC individuals were both responsible for the detoxification of halogenated aromatic hydrocarbon substances.CONCLUSIONS:Both beneficial and harmful factors had been detected in healthy YADC individuals,functionally,they may have triggered homeostasis to maintain the health of individuals with YADC.The homeostasis may be maintained by beneficial and harmful factors from gut flora and genes.Future studies are expected to focus on halogenated aromatic hydrocarbons and their detoxification processes. | ZHANG Huixiang WANG Limei GUO Jipeng WANG Jiai ZHANG Qianqian WANG Yutao LIU Xun ZHANG Lihuan SHI Lanlan WU Hongxiang CAO Xue | 2022 | Journal of Traditional Chinese Medicine2022,42,1: | 0 |
