2Triboelectric–Electromagnetic Hybrid Generator for Harvesting Blue Energy显示文摘Progress has been developed in harvesting lowfrequency and irregular blue energy using a triboelectric–electromagnetic hybrid generator in recent years. However,the design of the high-efficiency, mechanically durable hybrid structure is still challenging. In this study, we report a fully packaged triboelectric–electromagnetic hybrid generator(TEHG), in which magnets were utilized as the trigger to drive contact–separation-mode triboelectric nanogenerators(CS-TENGs) and coupled with copper coils to operate rotary freestanding-mode electromagnetic generators(RF-EMGs). The magnet pairs that produce attraction were used to transfer the external mechanical energy to the CS-TENGs, and packaging of the CS-TENGpart was achieved to protect it from the ambient environment. Under a rotatory speed of 100 rpm, the CS-TENGs enabled the TEHG to deliver an output voltage, current,and average power of 315.8 V, 44.6 μA, and ~ 90.7 μW,and the output of the RF-EMGs was 0.59 V, 1.78 m A, and 79.6 μW, respectively. The cylinder-like structure made the TEHG more easily driven by water flow and demonstrated to work as a practical power source to charge commercial capacitors. It can charge a 33μF capacitor from 0 to 2.1 V in 84 s, and the stored energy in the capacitor can drive an electronic thermometer and form a self-powered water-temperature sensing system.Huiyun Shao Ping Cheng Ruixuan Chen Lingjie Xie Na Sun Qingqing Shen Xiaoping Chen Qianqian Zhu Yi Zhang Yina Liu Zhen Wen Xuhui Sun 2018Nano-Micro Letters2018,10,3:9
3Review of ice-pavement adhesion study and development of hydrophobic surface in pavement deicing显示文摘Ice adhesion to materials is a significant concern in many fields. Hydrophobic surface has been used for anti-icing in fields of aircraft or transmission line, which prove to be efficacious and economical. However, such technique is seldom employed for road deicing,because of the texture and service environment of pavement. Instead, deicers such as rock salt are frequently used, which leads to serious corrosion problem of roads and bridges. In this paper, a number of studies that characterize mechanism of ice adhesion to common substrates, specifically to pavement, are reviewed. The most important researches undertaken on ice adhesion strength affecting factors are presented. An overview of studies carried out to find hydrophobic surface for asphalt and cement concrete pavement antiicing are presented. It was verified that the hydrophobicity had high correlation with icephobicity, and nano-engineered asphalt and cement concrete pavement surface exhibited favorable hydrophobicity, and also had good performance on weakening pavement-ice bonding. However, most ice-repelling pavements obtain hydrophobic surface via low surface energy coating, which could not exist on pavement for a long time under wheel abrasion. And the nano/micro structures on hydrophobic surfaces are also vulnerable and consumable. Thus, the long-term effect of hydrophobic surface still need to be improved,and durability of the hydrophobic surface should be the research and development priorities of ice-repelling pavement.Huaxin Chen Yongchang Wu Huiyun Xia Bingyin Jing Qingjiang Zhang 2018Journal of Traffic and Transportation Engineering(English Edition)2018,5,3:9
4Low-noise 1.3 μm InAs/GaAs quantum dot laser monolithically grown on silicon显示文摘We report low-noise, high-performance single transverse mode 1.3 μm InAs/GaAs quantum dot lasers monolithically grown on silicon(Si) using molecular beam epitaxy. The fabricated narrow-ridge-waveguide Fabry–Perot(FP) lasers have achieved a room-temperature continuous-wave(CW) threshold current of 12.5 mA and high CW temperature tolerance up to 90°C. An ultra-low relative intensity noise of less than-150 dB∕Hz is measured in the 4–16 GHz range. Using this low-noise Si-based laser, we then demonstrate 25.6 Gb/s data transmission over13.5 km SMF-28. These low-cost FP laser devices are promising candidates to provide cost-effective solutions for use in uncooled Si photonics transmitters in inter/hyper data centers and metropolitan data links.MENGYA LIAO SIMING CHEN ZHIXIN LIU YI WANG LALITHA PONNAMPALAM ZICHUAN ZHOU JIANG WU MINGCHU TANG SAMUEL SHUTTS ZIZHUO LIU PETER M.SMOWTON SIYUAN YU ALWYN SEEDS HUIYUN LIU 2018Photonics Research2018,,11:7
5Novel soybean peptide iglycin ameliorates insulin resistance of high-fat diet fed C57BL/6J mice and differentiated 3T3L1 adipocytes with improvement of insulin signaling and mitochondrial function显示文摘Soy consumption has been associated with potential health benefits in reducing chronic diseases.These physiological functions have been attributed to soy proteins or more commonly to bioactive peptides.Thus,more studies are required to identify these bioactive peptides,and elucidate their biological mechanisms of action.In the present study,a novel peptide iglycin was purifi ed from soybean seeds with a molecular mass of 3.88 k Da.Thereafter,iglycin reduced fasting blood glucose and restored insulin sensitivity of C57 BL/6 J mice on a high-fat diet with increased phosphorylation of insulin receptor substrate 1(IRS1)and AKT in adipose tissue.Furthermore,it improved glucose uptake,induced translocation of intracellular GLUT4 to plasma membrane and activation of insulin signaling in adipocytes under insulin-resistant condition.In addition,it decreased reactive oxygen species production,lipid peroxidation and inhibited adipocyte apoptosis with improved mitochondrial function as evidenced by up-regulation of succinate dehydrogenase activity,mitochondrial membrane potential and intracellular ATP store.These data suggested that iglycin ameliorated insulin resistance via activation of insulin signaling,which was associated with inhibition of oxidative stress,adipocyte apoptosis,and improvement of mitochondrial function.Yinghuan Wu Ran Zhao Minxia Li Huiyun Li Zhengwang Chen Yanying Zhao 2022Food Science and Human Wellness2022,11,6:3
6Chitosan and β-cyclodextrin Microspheres as Pulmonary Sustained Delivery Systems显示文摘Chitosan andβ-cyclodextrin were used to prepare microspheres with theophylline for pulmonary delivery by spray drying method.The characteristics,mucociliotoxicity,permeation rate and drug release were studied.The drug entrapments of microspheresⅠ,ⅡandⅢ were from 35.70%to 21.09% and 13.33%,while yields and encapsulation efficiencies were higher than 45% and about 90% respectively. The microspheres possessed low tap densities(0.34-0.48 g/cm3),appropriate diameters(3.35-3.94μm)and theoretical aerodynamics diameters(2.20-3.04μm).SEM images showed the microspheres were spherical with smooth or wrinkled surface surfaces.FT-IR demonstrated theophylline had formed hydrogen bonds with chitosan and β-cyclodextrin.The microspheres could effectively reduce the ciliotoxicity and easy to penetrate the memberine.The in vitro release of the microspheres was related to the ratio of drug/polymer and microspheresⅡ had a prolong release,providing the release of 72.00%in 12 h.The results suggestes that chitosan/β-cyclodextrin microspheresⅡare a promising carrier as sustained release for pulmonary delivery.ZHANG Weifen CHEN Xiguang LI Piwu HE Qiangzhi ZHOU Huiyun CHA Dongsu 2008Journal of Wuhan University of Technology(Materials Science)2008,23,4:2
7VGLUT3 neurons in median raphe control the efficacy of spatial memory retrieval via ETV4 regulation of VGLUT3 transcription显示文摘The raphe nucleus is critical for feeding, rewarding and memory. However, how the heterogenous raphe neurons are molecularly and structurally organized to engage their divergent functions remains unknown. Here, we genetically target a subset of neurons expressing VGLUT3. VGLUT3 neurons control the efficacy of spatial memory retrieval by synapsing directly with parvalbumin-expressing GABA interneurons(PGIs) in the dentate gyrus. In a mouse model of Alzheimer's disease(AD mice),VGLUT3→PGIs synaptic transmission is impaired by ETV4 inhibition of VGLUT3 transcription. ETV4 binds to a promoter region of VGLUT3 and activates VGLUT3 transcription in VGLUT3 neurons. Strengthening VGLUT3→PGIs synaptic transmission by ETV4 activation of VGLUT3 transcription upscales the efficacy of spatial memory retrieval in AD mice. This study reports a novel circuit and molecular mechanism underlying the efficacy of spatial memory retrieval via ETV4 inhibition of VGLUT3 transcription and hence provides a promising target for therapeutic intervention of the disease progression.Aodi He Chen Zhang Xiao Ke Yao Yi Quntao Yu Tongmei Zhang Hongyan Yu Huiyun Du Hao Li Qing Tian Ling-Qiang Zhu Youming Lu 2022Science China(Life Sciences)2022,65,8:2
8A regeneration system using cotyledons and cotyledonary node explants of Toona ciliata显示文摘We used the cotyledons and cotyledonary nodes of Toona ciliata(Chinese mahogany)as explants to examine callus and adventitious shoot induction when exposed to different ratios of hormones.We also investigated the effects of seedling age,inoculation method,and genotype on the efficient regeneration of T.ciliata.The results showed that different genotypes exhibited significantly different callus induction efficiency.The cotyledons and cotyledonary nodes of 20-day seedlings inoculated onto MS medium with 0.5 mg/L 6-benzylaminopurine(6-BA),0.5 mg/L kinetin(KT)and 0.05 mg/L 1-naphthylacetic acid(NAA)achieved a greater regeneration rate than did other concentrations of cytokinin and auxin.The numbers of shoots per cotyledon and cotyledonary node explant were 7.33 and 6.67.The optimal inoculation method for cotyledons was that the distal end of the explants was placed in contact with the medium.The optimal adventitious shoot differentiation medium for cotyledon explants was MS medium containing 0.3 mg/L 6-BA and 0.2 mg/L NAA,producing a 3.4 cm height of shoot on average.This study established an efficient regeneration system for T.ciliata with cotyledons and cotyledonary nodes as explants.Huiyun Song Wenmai Mao Yuanyuan Shang Wei Zhou Pei Li Xiaoyang Chen 2021Journal of Forestry Research2021,32,3:2

11Chronic hypoperfusion due to intracranial large artery stenosis is not associated with cerebralβ-amyloid deposition and brain atrophy显示文摘Background:Insufficient cerebral perfusion is suggested to play a role in the development of Alzheimer disease(AD).However,there is a lack of direct evidence indicating whether hypoperfusion causes or aggravates AD pathology.We investigated the effect of chronic cerebral hypoperfusion on AD-related pathology in humans.Methods:We enrolled a group of cognitively normal patients(median age:64 years)with unilateral chronic cerebral hypoperfusion.Regions of interest with the most pronounced hypoperfusion changes were chosen in the hypoperfused region and were then mirrored in the contralateral hemisphere to create a control region with normal perfusion.11C-Pittsburgh compound-positron emission tomography standard uptake ratios and brain atrophy indices were calculated from the computed tomography images of each patient.Results:The median age of the 10 participants,consisting of 4 males and 6 females,was 64 years(47-76 years).We found that there were no differences in standard uptake ratios of the cortex(volume of interest[VOI]:P=0.721,region of interest[ROI]:P=0.241)and grey/white ratio(VOI:P=0.333,ROI:P=0.445)and brain atrophy indices(Bicaudate,Bifrontal,Evans,Cella,Cella media,and Ventricular index,P>0.05)between the hypoperfused regions and contralateral normally perfused regions in patients with unilateral chronic cerebral hypoperfusion.Conclusion:Our findings suggest that chronic hypoperfusion due to large vessel stenosis may not directly induce cerebralβ-amyloid deposition and neurodegeneration in humans.Dongyu Fan Huiyun Li Dongwan Chen Yang Chen Xu Yi Heng Yang Qianqian Shi Fangyang Jiao Yi Tang Qiming Li Fangyang Wang Shunan Wang Rongbing Jin Fan Zeng Yanjiang Wang 2022Chinese Medical Journal2022,,5:1
12Extensive expansion of the chemical diversity of fusidane-type antibiotics using a stochastic combinational strategy显示文摘Fusidane-type antibiotics,represented by helvolic acid,fusidic acid and cephalosporin P1,are fungi-derived antimicrobials with little cross-resistance to commonly used antibiotics.Generation of new fusidane-type derivatives is therefore of great value,but this is hindered by available approaches.Here,we developed a stochastic combinational strategy by random assembly of all the post-tailoring genes derived from helvolic acid,fusidic acid,and cephalosporin P1 biosynthetic pathways in a strain that produces their common intermediate.Among a total of 27 gene combinations,24 combinations produce expected products and afford 58 fusidane-type analogues,of which 54 are new compounds.Moreover,random gene combination can induce unexpected activity of some post-tailoring enzymes,leading to a further increase in chemical diversity.These newly generated derivatives provide new insights into the structure-activity relationship of fusidane-type antibiotics.The stochastic combinational strategy established in this study proves to be a powerful approach for expanding structural diversity of natural products.Xiaojun Song Jianming Lv Zhiqin Cao Huiyun Huang Guodong Chen Takayoshi Awakawa Dan Hu Hao Gao Ikuro Abe Xinsheng Yao 2021Acta Pharmaceutica Sinica B2021,11,6:1
13Recent progress in epitaxial growth of Ⅲ–Ⅴ quantum-dot lasers on silicon substrate显示文摘In the past few decades,numerous high-performance silicon(Si)photonic devices have been demonstrated.Si,as a photonic platform,has received renewed interest in recent years.Efficient Si-basedⅢ–Ⅴquantum-dot(QDs)lasers have long been a goal for semiconductor scientists because of the incomparable optical properties of Ⅲ–Ⅴcompounds.Although the material dissimilarity betweenⅢ–Ⅴmaterial and Si hindered the development of monolithic integrations for over 30 years,considerable breakthroughs happened in the 2000s.In this paper,we review recent progress in the epitaxial growth of various Ⅲ–ⅤQD lasers on both offcut Si substrate and on-axis Si(001)substrate.In addition,the fundamental challenges in monolithic growth will be explained together with the superior characteristics of QDs.Shujie Pan Victoria Cao Mengya Liao Ying Lu Zizhuo Liu Mingchu Tang Siming Chen Alwyn Seeds Huiyun Liu 2019Journal of Semiconductors2019,40,10:1
14CmMLO17 and its partner CmKIC potentially support Alternaria alternata growth in Chrysanthemum morifolium显示文摘The Mildew Resistance Locus O(MLO)gene family has been investigated in many species.However,there are few studies on chrysanthemum MLO genes.We report in this study that CmMLO17 in Chrysanthemum morifolium was upregulated after Alternaria alternata infection.Silencing of CmMLO17 by artificial microRNA resulted in reduced susceptibility of chrysanthemum to A.alternata infection.Genes in the abscisic acid(ABA)and Ca 2+signaling pathways were upregulated in the CmMLO17-silenced line R20 compared to the wild-type plants.We speculated that CmMLO17-silenced plants had a faster and stronger defense response that was mediated by the ABA and Ca 2+signaling pathways,resulting in reduced susceptibility of chrysanthemum to A.alternata infection.In addition,a candidate gene,CmKIC,that may interact with CmMLO17 was discovered by the yeast two-hybrid assay.The interaction between CmMLO17 and CmKIC was confirmed using the yeast two-hybrid assay and bimolecular fluorescence complementation(BiFC)analysis.CmMLO17 and CmKIC were both located on the plasma membrane,and CmKIC was also located on the nucleus.CmKIC overexpression increased the susceptibility of chrysanthemum to A.alternata,whereas CmKIC silencing resulted in reduced susceptibility.Therefore,CmMLO17 and CmKIC may work together in C.morifolium to support the growth of A.alternata.The results of this study will provide insight into the potential function of MLO and improve the understanding of plant defense responses to necrotrophic pathogens.Jingjing Xin Ye Liu Huiyun Li Sumei Chen Jiafu Jiang Aiping Song Weimin Fang Fadi Chen 2021Horticulture Research2021,8,1:1

17Two pseudo-polymorphic porous POM-pillared MOFs for sulfide-sulfoxide transformation: Efficient synergistic effects of POM precursors, metal sites and microstructures显示文摘Developing sustainable and powerful heterogeneous catalytic systems to convert sulfides into high-value sulfoxide products has become a particularly appealing field and an arduous challenge.In this work,two porous polyoxometalate-pillared metal-organic frameworks,formulated as H_(3n)[Cu_(3)(pidc)_(2)(H_(2)O)_(2.5)]_(2)[PW_(12)O_(40)]_n·x H_(2)O (n=1.5,x=6 for 1,n=1,x=12 for 2;and H_(3)pidc=2-(3-pyridinyl)-1H-imidazole-4,5-dicarboxylic acid),were consciously manufacture and employed for heterogeneously catalyzed sulfide-sulfoxide transformation.Structural analysis shows that 1 and 2 exhibit similar porous frameworks with nearly identical two-dimensional metal-organic layers further pillared by tetradentate POM ligands with different coordination modes,which also result in the porosity of 1 being almost twice that of 2.In catalyzing the conversion of methyl phenyl sulfide (MPS) to methyl phenyl sulfoxide (MPSO),1 can convert nearly 100%of MPS into MPSO within 30 min,while 2 achieved the similar results requires 50 min.The higher activity of 1 may be attributed to its larger channel that can provide more active sites and more efficient mass transfer process.Systematic structure-activity analyses and mechanistic studies revealed dual-reaction pathways driven by POM sites and metal sites assisted by the structural microenvironment.Yanhong Chen Haiyan An Shenzhen Chang Yanqin Li Tieqi Xu Qingshan Zhu Huiyun Luo Yaohui Huang Yuting Wei 2023Chinese Chemical Letters2023,34,7:0
18Variation for Resistance to Alternaria tenuissima and Potential Structural Mechanism among Different Cultivars of Chrysanthemum morifolium显示文摘Black spot disease,caused by the necrotrophic fungus Alternaria tenuissima(Fr.)Wiltsh(A.tenuissima),is considered a highly destructive disease of Chrysanthemum(Chrysanthemum morifolium Ramat.).A set of 17 accessions of commercial chrysanthemum cultivars were evaluated for resistance to A.tenuissima by seedling artificial inoculation.It was found that the reaction of the accessions to artificial inoculation ranged from resistant to highly susceptible.Five varieties of chrysanthemum(‘Zhongshan Taogui’,‘Jinba’,‘Zhongshan Jinguan’,‘Jinling Wanhuang’and‘Jinling Yangguang’)were resistant;two varieties of chrysanthemum(‘Zhongshan Xinggui’and‘Zhongshan Jinkui’)were moderately resistant;and others were susceptible to various degrees,four varieties of chrysanthemum(‘Zhongshan Zihe’,‘Zhongshan Jiuhong’,‘Zaoyihong’and‘Jinling Jiaohuang’)were highly susceptible,especially.Some leaf morphological features of two resistant and two highly susceptible cultivars were further researched.Trichome density,length,height,gland size and stomata density were found to be associated with plant passive resistance.Resistant varieties that were identified in present study will be promising germplasm for exploitation of breeding programmes aimed at developing A.tenuissima-resistant cultivars and increasing genetic diversity.Huiyun Li Ye Liu Sumei Chen Jiafu Jiang Aiping Song Weimin Fang Fadi Chen 2020Phyton-International Journal of Experimental Botany2020,89,4:0
19Quantum dot mode-locked frequency comb with ultra-stable 25.5 GHz spacing between 20℃ and 120℃显示文摘Semiconductor mode-locked lasers(MLLs)are promising frequency comb sources for dense wavelength-divisionmultiplexing(DWDM)data communications.Practical data communication requires a frequency-stable comb source in a temperature-varying environment and a minimum tone spacing of 25 GHz to support high-speed DWDM transmissions.To the best of our knowledge,however,to date,there have been no demonstrations of comb sources that simultaneously offer a high repetition rate and stable mode spacing over an ultrawide temperature range.Here,we report a frequency comb source based on a quantum dot(QD)MLL that generates a frequency comb with stable mode spacing over an ultrabroad temperature range of 20–120℃.The two-section passively mode-locked In As QD MLL comb source produces an ultra-stable fundamental repetition rate of 25.5 GHz(corresponding to a 25.5 GHz spacing between adjacent tones in the frequency domain)with a variation of 0.07 GHz in the tone spacing over the tested temperature range.By keeping the saturable absorber reversely biased at-2 V,stable mode-locking over the whole temperature range can be achieved by tuning the current of the gain section only,providing easy control of the device.At an elevated temperature of 100℃,the device shows a 6 d B comb bandwidth of 4.81 nm and 31 tones with>36 d B optical signal-to-noise ratio.The corresponding relative intensity noise,averaged between 0.5 GHz and 10 GHz,is-146 d Bc∕Hz.Our results show the viability of the In As QD MLLs as ultra-stable,uncooled frequency comb sources for low-cost,large-bandwidth,and low-energy-consumption optical data communications.SHUJIE PAN JIANOU HUANG ZICHUAN ZHOU ZHIXIN LIU LALITHA PONNAMPALAMZIZHUO LIU MINGCHU TANG MU-CHIEH LO ZIZHENG CAO KENICHI NISHI KEIZO TAKEMASA MITSURU SUGAWARA RICHARD PENTY IAN WHITE ALWYN SEEDS HUIYUN LIU SIMING CHEN 2020Photonics Research2020,8,12:0
20SINGLET OXYGEN DETECTION DURING PHOTOSENSITIZATION显示文摘Singlet oxygen(^(1)O_(2))is a highly reactive oxygen species involved in numerous chemical and photochemical reactions in diferent biological systems and in particular,in photodynamic therapy(PDT).However,the quantifcation of^(1)O_(2) generation during in vitro and in vivo pho-tosensitization is still technically challenging.To address this problem,indirect and direct methods for^(1)O_(2)detection have been intensively studied.This review presents the available methods currently in use or under development for detecting and quantifying^(1)O_(2) generation during photosensitization.The advantages and limitations of each method will be presented.Moreover,the future trends in developing PDT-^(1)O_(2) dosimetry will be briefly discussed.BUHONG LI HUIYUN LIN DEFU CHEN BRIAN C.WILSON YING GU 2013Journal of Innovative Optical Health Sciences2013,6,1:0
