| 1 | Effects of Citric Acid on Hydration Process and Mechanical Properties of Thermal Decomposed Magnesium Oxychloride Cement显示文摘In order to make full use of salt lake magnesium resources and improve the strength of the thermal decomposed magnesium oxychloride cement(TDMOC), the effects of citric acid on the hydration process and mechanical properties of TDMOC was studied. The hydration heat release at initial 24 h and strengths at 3, 7, and 28 days of TDMOC specimens were conducted. The hydration products and paste microstructure were analyzed by XRD, FT-IR and SEM, respectively. The results showed that citric acid can not only reduce the 24 h hydration heat release and delay the occurring time of second peak of TDMOC, but also produce more 5Mg(OH)2·MgCl 2·8H2O and less Mg(OH)2 in hydration process of TDMOC. More perfect and slender crystals were observed in the microstructure of the TDMOC pastes with citric acid. The results demonstrated that citric acid as an additive of TDMOC can decrease the hydration heat release and increase the compressive strength and flexural strength of TDMOC. The possible mechanism for the strength enhancement was discussed. | 文静 余红发 LI Ying WU Chengyou DONG Jinmei | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，1： | 7 |
| 2 | Bruceine D inhibits HIF-1α-mediated glucose metabolism in hepatocellular carcinoma by blocking ICAT/β-catenin interaction显示文摘Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related deaths,characterized by highly hypoxic tumor microenvironment.Hypoxia-inducible factor-1α(HIF-1α)is a major regulator involved in cellular response to changes of oxygen levels,supporting the adaptation of tumor cells to hypoxia.Bruceine D(BD)is an isolated natural quassinoid with multiple anti-cancer effects.Here,we identified BD could significantly inhibit the HIF-1α expression and its subsequently mediated HCC cell metabolism.Using biophysical proteomics approaches,we identified inhibitor of β-catenin and T-cell factor(ICAT)as the functional target of BD.By targeting ICAT,BD disrupted the interaction of bcatenin and ICAT,and promoted β-catenin degradation,which in turn induced the decrease of HIF-1α expression.Furthermore,BD could inhibit HCC cells proliferation and tumor growth in vivo,and knockdown of ICAT substantially increased resistance to BD treatment in vitro.Our data highlight the potential of BD as a modulator of β-catenin/HIF-1α axis mediated HCC metabolism. | Rui Huang Lijun Zhang Jinmei Jin Yudong Zhou Hongwei Zhang Chao Lv Dong Lu Ye Wu Hong Zhang Sanhong Liu Hongzhuan Chen Xin Luan Weidong Zhang | 2021 | Acta Pharmaceutica Sinica B2021，11，11： | 4 |
| 3 | Macroporous 3D carbon-nitrogen(CN)confined MoO_(x) catalyst for enhanced oxidative desulfurization of dibenzothiophene显示文摘Macroporous 3D carbon doped with nitrogen confined Mo catalyst(MoO_(x)@CN)had been prepared by a facile one-step pyrolysis technique using silica as a template and was employed for oxidative desulfurization(ODS)of dibenzothiophene(DBT)in model fuel with H2O_(2) as oxidant.The effect of different ope rating conditions(i.e.,reaction te mperature and time,catalyst dosage,H2O_(2)/DBT(O/S)molar ratio)were also systematic investigated.Under the optimal reaction condition,MoO_(x)@CN catalyst exhibited highly excellent ODS performance toward DBT,the highest sulfur removal efficiency can be up to 99.9%and sulfur content was wiped out from 800 ppm to 10 ppm.Due to the robust 3D structure promoting rapid transfer,in addition to the increased number of active sites induced by the Mo vacancies,the catalyst,prepared using chitosan and ammonium heptamolybdate in a mass ratio of 1:0.5,displayed rapid kinetics and low activation energy in the oxidation of dibenzothiophene.Moreover,it exhibited excellent recyclability after five cycles without any obvious decrease in catalytic activity for the oxidative desulfurization reaction. | Jinmei Ye Jie Wen Dongdong Zhao Peilun Zhang Airong Li Lianhong Zhang Hui Zhang Mengqi Wu | 2020 | Chinese Chemical Letters2020，31，10： | 3 |
| 4 | Stable isotope geochemical characteristics of dissolved inorganic carbon in the Jiulong River Estuary, Fujian Province, China显示文摘The isotopic composition of dissolved inorganic carbon(DIC) in estuarine environments has been studied for its significant role in determining the isotopic composition of inorganic/organic matter and its applications to the study of various natural processes. In this paper, based on the stable isotope geochemical characteristics of dissolved inorganic carbon in the Jiulong River Estuary, the following conclusions are drawn:(1) δ13CDIC values are mainly controlled by the mixing ratio of fresh water and sea water;(2) δ13Cphytoplankton values are linearly related to the δ13CDIC values;(3) δ13CPOM values for the Jiulong River Estuary are affected by anthropogenic pollution significantly; and(4) the comprehensive analysis of δ13Cphytoplankton, δ13CPOM and δ13CDIC shows that along with increasing salinity, the proportion of POM derived from the degradation of phytoplanktons gradually increases. | LIU Qiming WU Qiong CAO Yinglan LIN Jinmei JIAO Yupei | 2014 | Chinese Journal Of Geochemistry2014，33，2： | 2 |
| 5 | High-power linear-polarization burst-mode all-fibre laser and generation of frequency-adjustable microwave signal显示文摘Narrowband microwave generation with tuneable frequency is demonstrated by illuminating a photoconductive semiconductor switch(PCSS)with a burst-mode fibre laser.The whole system is composed of a high-power linearly polarized burst-mode pulsed fibre laser and a linear-state PCSS.To obtain a high-performance microwave signal,a desired envelope of burst is necessary and a pulse pre-compensation technique is adopted to avoid envelope distortion induced by the gain-saturation effect.Resulting from the technique,homogenous peak power distribution in each burst is ensured.The maximum energy of the laser burst pulse reaches 200μJ with a burst duration of 100 ns at the average power of 10 W,corresponding to a peak power of 4 kW.When the PCSS is illuminated by the burst-mode fibre laser,narrowband microwave generation with tuneable frequency(0.80-1.12 GHz)is obtained with a power up to 300 W.To the best of the authors’knowledge,it is the first demonstration of frequency-tuneable narrowband microwave generation based on a fibre laser.The high-power burst-mode fibre laser reported here has great potential for generating high-power arbitrary microwave signals for a great deal of applicable demands such as smart adaptive radar and intelligent high-power microwave systems. | Xuan He Bin Zhang Shuailin Liu Jinmei Yao Qilin Wu Yuxin Zhao Tao Xun Linyong Yang Jing Hou | 2021 | High Power Laser Science and Engineering2021，9，2： | 2 |

| 9 | The genomic and bulked segregant analysis of Curcuma alismatifolia revealed its diverse bract pigmentation显示文摘Compared with most flowers where the showy part comprises specialized leaves(petals)directly subtending the reproductive structures,most Zingiberaceae species produce showy“flowers”through modifications of leaves(bracts)subtending the true flowers throughout an inflorescence.Curcuma alismatifolia,belonging to the Zingiberaceae family,a plant species originating from Southeast Asia,has become increasingly popular in the flower market worldwide because of its varied and esthetically pleasing bracts produced in different cultivars.Here,we present the chromosome-scale genome assembly of C.alismatifolia“Chiang Mai Pink”and explore the underlying mechanisms of bract pigmentation.Comparative genomic analysis revealed C.alismatifolia contains a residual signal of whole-genome duplication.Duplicated genes,including pigment-related genes,exhibit functional and structural differentiation resulting in diverse bract colors among C.alismatifolia cultivars.In addition,we identified the key genes that produce different colored bracts in C.alismatifolia,such as F3′5'H,DFR,ANS and several transcription factors for anthocyanin synthesis,as well as chlH and CAO in the chlorophyll synthesis pathway by conducting transcriptomic analysis,bulked segregant analysis using both DNA and RNA data,and population genomic analysis.This work provides data for understanding the mechanism of bract pigmentation and will accelerate breeding in developing novel cultivars with richly colored bracts in C.alismatifolia and related species.It is also important to understand the variation in the evolution of the Zingiberaceae family. | Xuezhu Liao Yuanjun Ye Xiaoni Zhang Dan Peng Mengmeng Hou Gaofei Fu Jianjun Tan Jianli Zhao Rihong Jiang Yechun Xu Jinmei Liu Jinliang Yang Wusheng Liu Luke RTembrock Genfa Zhu Zhiqiang Wu | 2022 | aBIOTECH2022，3，3： | 1 |

| 12 | Highly selective kinetic resolution of D/L-syn-p-sulfone phenylserine catalyzed by D-threonine aldolase in two-phase ionic solvent显示文摘In the chemical synthesis of L-syn-p-methylsulfoxide phenylserine ethyl ester(D-ethyl ester),L-tartaric acid or enzymatic resolution is employed to resolve the racemate,and thus obtain the target compound,and the remaining isomer can be recycled to obtain the raw material.In this study,high-purity L-syn-p-methylsulfoxide phenylserine(L-syn-MPS)was obtained.The kinetics of the D-threonine aldolase enzymatic hydrolysis reaction reveals that D-syn-p-sulfoxylphenylserine resolves well in[BMIM][BF 4]ionic solvents.The D/L-syn-MPS racemate was resolved using a two-phase ionic solvent[BMIM][NTf 2]to afford L-syn-MPS(ee(enantiomeric excess)>99%)and a white solid in 41.7%yield.Therefore,this system is suitable for the separation of insoluble aldehydes and successfully avoids the condensation of hydroxyl aldehydes to form D-anti-MPS. | Fengfan Liu Zhihao Shi Jinmei Zhu Xiaobin Liang Mingming Liang Yuanyuan Xie Weike Su Jiequn Wu | 2023 | Green Chemical Engineering2023，4，2： | 0 |

| 14 | Nonlinear Phenomena Conveying Body Size Information and Improving Attractiveness of the Courtship Calls in the Males of Odorrana tormota显示文摘Nonlinear phenomena are commonly shown in the vocalization of animals and exerts different adaptive functions.Although some studies have pointed out that nonlinear phenomena can enhance the individual identification of male Odorrana tormota,whether the nonlinear phenomena play a specific role in the sexual selection of O.tormota remain unclear.Here we presented evidence that there was a significant negative correlation(Pearson:n=30,r=0.65,P<0.001)between the nonlinear phenomena content and snout-vent length in the male O.tormota,and two-choice amplexus experiments showed that female O.tormota preferred male with smaller body size containing higher nonlinear phenomena content in its calls.Phonotaxis experiments also revealed that females preferred calls with higher nonlinear phenomena content.Additionally,compared to the calls with lower nonlinear phenomena content and higher fundamental frequency,there was shorter response time in phonotactic behaviour of female induced by the calls with higher nonlinear phenomena content and lower fundamental frequency.We argue that the nonlinear phenomena content in the calls of male O.tormota can convey its body size information and may provide important clues for female frogs in darkened surroundings to identify males’body size during mate choice,meanwhile,higher nonlinear phenomena content in males’calls may increase the attractiveness of males to females.The results of this study provide confirmation that,for O.tormota,nonlinear phenomena have specific function in mate choice. | Yatao WU Jiahui BAO Pingshin LEE Jinmei WANG Sheng WANG Fang ZHANG | 2021 | Asian Herpetological Research2021，12，1： | 0 |
| 15 | Calls of the Large Odorous Frog(Odorrana graminea)Show Nonlinear and Individual Characteristics显示文摘Male large odorous frogs(Odorrana graminea)have been shown to have a rich vocal repertoire and their calls contain harmonics that extend into the ultrasonic range,much like calls of male O.tormota,a sympatric species.Whereas vocalizations of male O.tormota exhibit nonlinear characteristics and contain individual signatures,it is unclear whether or not those of O.graminea do.We carried out an extensive study of the vocalizations of male O.graminea with the goal of investigating whether they:(1)contained nonlinear phenomena(NLP),(2)carried individual signatures.We recorded and analyzed 1770 vocal calls from nine males.Their calls were classifiable into two distinct categories(one-note calls and multi-note calls).Of these,one-note complex/steep-frequency modulation call was the most abundant call-type.These calls showed diverse frequency modulation patterns,and abundant presence of NLP.Various basic spectral and temporal pa ra meters of such calls were individually distinct.Kruskal-Wallis Analysis of Rank test showed that the calls from individual males differed significantly.Subsequent discriminant function analysis(DFA)showed that 54.7%of the calls could be correctly assigned to individual.These results suggested that male O.graminea might be able to discriminate neighboring frogs from strangers acoustically.However,further research is necessary to demonstrate this capacity behaviorally. | Fang ZHANG Yatao WU Jinmei WANG Jiahui BAO | 2021 | Asian Herpetological Research2021，12，1： | 0 |
| 16 | Optimization of the in-situ growth conditions based on a novel photo-microcalorimeter for the sustainable cultivation of photosynthetic microorganisms显示文摘Despite the great potential of photosynthetic microbes in the production of renewable fuels,value-adding chemicals,and water treatment,etc.,commercial utilization of them is significantly hindered by the lack of techniques to accurately monitor the thermodynamic and kinetic characteristics of the in-situ growth of microbes under controlled light illumination for optimal cultivation.Herein,we demonstrated that a newly developed highly sensitive photo-microcalorimetric system successfully captured the impacts of the light wavelength and strength on the thermodynamic and kinetic parameters of the in-situ growth of Rhodopseudomonas palustris,a representative photosynthetic microorganism.To our best knowledge,this is the first time that highly precise microcalorimetry is employed to monitor exam the in-situ growth of photosynthetic microorganisms under controllable photo illumination.We envision this technique can help for the optimization of the growth conditions of photosynthetic microorganisms for scale-up applications. | YANJUAN LIAO DONGLING YU XIAOFANG QIN JINMEI WU HUI WEI HUI LI XIANGYING MA ZAIYIN HUANG | 2020 | BIOCELL2020，44，4： | 0 |
| 17 | Effect of temperature on the leaching of heavy metals from nickel mine tailings in the arctic area,Norway显示文摘The leaching of heavy metals from tailings deposit due to the oxidation of sulphidic tailings and formation of acidic leachate is considered a high risk to the surrounding environment.Temperature plays an important role in the leaching of heavy metals from tailings in changing acid-based environment,especially in the Arctic area.To investigate how the temperature variation affected metal release from tailings in the Arctic area,a series of column leaching experiments was conducted under four temperature situations(5°C,10°C,14°C and 18°C).Physicochemical properties,Fe,Zn,Ni and Mn concentrations of leachates at each cycle were measured,and multivariate statistical analysis was applied to research the effect of temperature on heavy metals leaching from tailings in the Arctic area.The results showed that higher temperatures encouraged tailings to oxidation and sulfuration of and promoted heavy metal release from the tailings through precipitation and erosion.Ni,Zn and Mn have similar releasing resources from tailings and positive correlation in the leaching activity.Rising temperature accelerated Fe leaching;Fe leaching promoted leaching of the other metals,especially of Mn.Appropriately increase temperature will accelerate oxidization and sulfidization of the tailings,promote acid generation and increase TDS and,finally,promote the release of heavy metals.Climate change,with rising temperatures increasing the risk of heavy metals leaching from the tailings,should be given greater attention.Keeping tailings away from the appropriate temperature and in a higher alkalinity is a good method to control the leaching of heavy metals from tailings. | Shuai Fu Jinmei Lu Ingar Walder Daishe Wu | 2023 | International Journal of Agricultural and Biological Engineering2023，16，2： | 0 |
