| 1 | Water in coesite: Incorporation mechanism and operation condition,solubility and P-T dependence, and contribution to water transport and coesite preservation显示文摘A series of coesite,coexisting with or without a liquid phase,was synthesized in the nominal system SiO2-H2O at800-1450℃and 5 GPa.Micro-Raman spectroscopy was used to identity the crystalline phase,electron microprobe and LA-ICP-MS were employed to quantity some major and trace elements,and unpolarized FTIR spectroscopy was applied to probe the different types of hydrogen defects,explore water-incorporation mechanisms and quantify water contents.Trace amounts of A1 and B were detected in the coesite.Combining our results with the results in the literatures,we have found no positive correlation between the Al contents and the'Al'-based hydrogen concentrations,suggesting that previously proposed hydrogen-incorporation mechanism H^++Al^3+■Si^4+does not function in coesite.In contrast,we have confirmed the positive correlation between the B contents and the B-based hydrogen concentrations.The hydrogen-incorporation mechanism H^++B3^+■Si^4+readily takes place in coesite at different P-T conditions,and significantly increases the water content at both liquid-saturated and liquid-undersaturated conditions.For the SiO2-H2O system,we have found that type-Ⅰhydrogarnet substitution plays a dictating role in incorporating water into coesite at liquid-saturated condition,type-II hydrogarnet substitution contributes significantly at nearly dry condition,and both operate at conditions in between.The water solubility of coesite,as dictated by the type-Ⅰhydrogarnet substitution,positively correlates with both P and T,cH2O=-105(30)+5.2(32)×P+0.112(26)×T,with cH2O in wt ppm,P in GPa and T in℃.Due to its low water solubility and small fraction in subducted slabs,coesite may contribute insignificantly to the vertical water transport in subduction zones.Furthermore,the water solubility of any coesite in exhuming ultra-high pressure metamorphic rocks should be virtually zero as coesite becomes metastable.With an adequately fast waterdiffusion rate,this metastable coesite should be completely dry,which may have been the key factor to the partial preservation of most natural Coe.As a byproduct,a new IR experimental protocol for accurate water determination in optically anisotropic nominally anhydrous minerals has been found.Aided with the empirical method of Paterson(1982)it employs multiple unpolarized IR spectra,collected from randomly-orientated mineral grains,to approximate both total integrated absorbance and total integrated molar absorption coefficient.Its success relies on a high-level orientation randomness in the IR analyses. | Wei Yan Yanyao Zhang Yunlu Ma Mingyue He Lifei Zhang Weidong Sun Christina Yan Wang Xi Liu | 2021 | Geoscience Frontiers2021,12,1: | 3 |
| 2 | Light-triggered nitric oxide release and structure transformation of peptide for enhanced intratumoral retention and sensitized photodynamic therapy显示文摘Tumor-targeted delivery of nanomedicine is of great importance to improve therapeutic efficacy of cancer and minimize systemic side effects.Unfortunately,nowadays the targeting efficiency of nanomedicine toward tumor is still quite limited and far from clinical requirements.In this work,we develop an innovative peptide-based nanoparticle to realize light-triggered nitric oxide(NO)release and structural transformation for enhanced intratumoral retention and simultaneously sensitizing photodynamic therapy(PDT).The designed nanoparticle is self-assembled from a chimeric peptide monomer,TPP-RRRKLVFFK-Ce6,which contains a photosensitive moiety(chlorin e6,Ce6),aβ-sheet-forming peptide domain(Lys-Leu-Val-Phe-Phe,KLVFF),an oligoarginine domain(RRR)as NO donor and a triphenylphosphonium(TPP)moiety for targeting mitochondria.When irradiated by light,the constructed nanoparticles undergo rapid structural transformation from nanosphere to nanorod,enabling to achieve a significantly higher intratumoral accumulation by 3.26 times compared to that without light irradiation.More importantly,the conversion of generated NO and reactive oxygen species(ROS)in a light-responsive way to peroxynitrite anions(ONOO)with higher cytotoxicity enables NO to sensitize PDT in cancer treatment.Both in vitro and in vivo studies demonstrate that NO sensitized PDT based on the well-designed transformable nanoparticles enables to eradicate tumors efficiently.The light-triggered transformable nanoplatform developed in this work provides a new strategy for enhanced intratumoral retention and improved therapeutic outcome. | Lingdong Jiang Danyang Chen Zhaokui Jin Chao Xia Qingqing Xu Mingjian Fan Yunlu Dai Jia Liu Yuanpei Li Qianjun He | 2022 | Bioactive Materials2022,7,6: | 3 |
| 3 | Adsorptive Behavior of Methyl Blue on Graphene Aerogel:A Mechanism Study显示文摘Graphene aerogel was synthesized and used for the removal of methyl blue from aqueous solutions.The effect of solution pH,temperature and adsorption time on the adsorption performance of the graphene aerogel was studied systematically.In addition,investigations were also performed to determine the nature of adsorption.The experimental results show that graphene aerogel is a highly efficient adsorbent for the treatment of methyl blue in aqueous solutions.In addition,the adsorption of methyl blue proceeds through a single layer physical adsorption on the graphene aerogel.The findings herein are useful for the future development of adsorbent for in water. | 宋旭艳 HE Yunlu PAN Xi WEI Min LI Ran ZHOU Xiaoyu 郑莹 李俊升 TANG Haolin | 2021 | Journal of Wuhan University of Technology(Materials Science)2021,36,2: | 2 |
| 4 | Colonization of endophyte Acremonium sp. D212 in Panax notoginseng and rice mediated by auxin and jasmonic acid显示文摘Endophytic fungi can be beneficial to plant growth. However, the molecular mechanisms under-lying colonization of Acremonium spp. remain unclear. In this study, a novel endophytic Acremonium strain was isolated from the buds of Panax notoginseng and named Acremonium sp. D212. The Acremonium sp. D212 could colonize the roots of P. notoginseng, enhance the resistance of P. notoginseng to root rot disease, and promote root growth and saponin bio-synthesis in P. notoginseng. Acremonium sp. D212 could secrete indole-3-acetic acid (IAA) and jasmonic acid (JA), and inoculation with the fungus increased the endogenous levels of IAA and JA in P. noto-ginseng. Colonization of the Acremonium sp. D212 in the roots of the rice line Nipponbare was dependent on the concentration of methyl jasmonate (MeJA) (2–15μmol/L) and 1-naphthalenacetic acid (NAA) (10–20μmol/L). Moreover, the roots of the JA signaling-defective coi1-18 mutant were colonized by Acremonium sp. D212 to a lesser degree than those of the wild-type Nipponbare and miR393b-overexpressing lines, and the colonization was res-cued by MeJA but not by NAA. It suggests that the cross-talk between JA signaling and the auxin biosynthetic pathway plays a crucial role in the colonization of Acremonium sp. D212 in host plants. | Li Han Xuan Zhou Yiting Zhao Shusheng Zhu Lixia Wu Yunlu He Xiangrui Ping Xinqi Lu Wuying Huang Jie Qian Lina Zhang Xi Jiang Dan Zhu Chongyu Luo Saijie Li Qian Dong Qijing Fu Kaiyuan Deng Xin Wang Lei Wang Sheng Peng Jinsong Wu Weimin Li JiǐíFriml Youyong Zhu Xiahong He Yunlong Du | 2020 | Journal of Integrative Plant Biology2020,62,9: | 2 |
| 5 | Synthesis and Characterization of Fluorodinitrobenzenes with Tunable Melting Point:Potential Low Sensitive Energetic Plasticizer and Melt-Cast Carrier显示文摘of main observation and conclusion In order to explore the effects of fluoro substituents on the energy and safety of energetic compounds,a series of fluorodinitrobenzenes including l,3-difluoro-2,4-dinitrobenzene(1),1,5-difluoro-2,4-dinitrobenzene(2),1,2,3-trifluoro-4,6-dinitrobenzne(3)and 1,3,5-trifluoro-2,4-dinitrobenzene(4)were prepared.All the compounds were fully characterized.The structures of 2 and 3 were further confirmed by single crystal X-ray diffraction analysis.The results show that these compounds exhibit comparable detonation properties(D=6703-6978 m s^-1,and p=21.3-23.76Pa)to those of 2,4,6-trinitrotoluene(TNT)due to the significantly increased density of fluorine introduced.Low sensitivity(IS>40 J,and FS>360 N)of these compounds along with different melting points make them potential candidates for different allocation.Among them,1 and 4 with the melting point of 42.5℃and 55.2℃,respectively,show promise for application in the field of energetic plasticizer.Compounds 2 and 3 are potential low sensitive melt-cast carrier due to their similar melting point and superior detonation performance to that of TNT. | Yunlu Li Peng Chen Yan Liu Ping Yin Chunlin He Siping Pang | 2020 | Chinese Journal of Chemistry2020,38,12: | 2 |

| 9 | Deposition of IrO_(2) on Nb-doped SnO_(2) as Electrocatalysts for Oxygen Evolution Reactions显示文摘We reported sol-gel-derived Nb-doped SnO_(2) which is an effective catalyst carrier for deposition of IrO_(2),and the electrocatalytic activity of the synthesized catalysts for OER was investigated.It is found that the doping of Nb can refine the SnO_(2) crystal grains and improve the electrical conductivity of SnO_(2).When the doping amount of Nb is 7%,the electrical conductivity of Nb-SnO_(2) reaches a maximum value of 3.54 S/cm.With the increase in the loading amount of IrO_(2),the electrocatalytic activity towards OER of the thus-synthesized catalysts is improved,reaching a comparable OER activity with pristine IrO_(2) with the loading content of about 44wt%. | 宋旭艳 HE Yunlu PENG Sanwen WANG Bo DONG Ping TANG Haolin 余军 | 2022 | Journal of Wuhan University of Technology(Materials Science)2022,37,6: | 0 |
| 10 | Non-cooperative game for network access selection in heterogeneous integrated networks显示文摘The integration of different heterogeneous access networks is one of the remarkable characteristics of the next generation network,in which users with multi-network interface terminals can independently select access network to obtain the most desired service.A kind of unified quantification model of non-monotone quality of service(QoS) and a model of non-cooperative game between users and networks are proposed for heterogeneous network access selection.An optimal network pricing mechanism could be formulated by using a novel strategy which is used in this non-cooperative game model to balance the interests of both the users and the networks.This access network selection mechanism could select the most suitable network for users,and it also could provide the basis when formulating QoS standards in heterogeneous integrated networks.The simulation results show that this network selection decision-making algorithm can meet the users' demand for different levels service in different scenes and it can also avoid network congestion caused by unbalanced load. | 郭洪尧 Zhang Xin He Yunlu Jiang Rui Xie Jiangbo | 2014 | High Technology Letters2014,20,3: | 0 |
