| 1 | Degradation kinetics and mechanism of aniline by heat-assisted persulfate oxidation显示文摘Oxidation of aniline by persulfate in aqueous solutions was investigated and the reaction kinetic rates under different temperature, persulfate concentration and pH conditions were examined in batch experiments. The results showed that, the aniline degradation followed pseudo first-order reaction model. Aniline degradation rate increased with increasing temperature or persulfate concentration. In the pH range of 3 to 11, a low aniline degradation rate was obtained at strong acid system (pH 3), while a high degradation rate was achieved at strong alkalinity (pH 11). Maximum aniline degradation occurred at pH 7 when the solution was in a weak level of acid and alkalinity (pH 5, 7 and 9). Produced intermediates during the oxidation process were identified using liquid chromatography-mass spectrometry technology. And nitrobenzene, 4-4’-diaminodiphenyl and 1-hydroxy-1,2-diphenylhydrazine have been identified as the major intermediates of aniline oxidation by persulfate and the degradation mechanism of aniline was also tentatively proposed. | Xiaofang Xie Yongqing Zhang Weilin Huang Shaobing Huang | 2012 | Journal of Environmental Sciences2012，24，5： | 25 |
| 2 | Artificial root exudates and soil organic carbon mineralization in a degraded sandy grassland in northern China显示文摘Plant root exudates contain various organic and inorganic components that include glucose, citric and oxalic acid. These components affect rhizosphere microbial and microfaunal activities, but the mechanisms are not fully known. Studies concerned from degraded grassland ecosystems with low soil carbon(C) contents are rare, in spite of the global distribution of grasslands in need of restoration. All these have a high potential for carbon sequestration, with a reduced carbon content due to overutilization. An exudate component that rapidly decomposes will increase soil respiration and CO2 emission, while a component that reduces decomposition of native soil carbon can reduce CO2 emission and actually help sequestering carbon in soil. Therefore, to investigate root exudate effects on rhizosphere activity, citric acid, glucose and oxalic acid(0.6 g C/kg dry soil) were added to soils from three biotopes(grassland, fixed dune and mobile dune) located in Naiman, Horqin Sandy Land, Inner Mongolia, China) and subjected to a 24-day incubation experiment together with a control. The soils were also analyzed for general soil properties. The results show that total respiration without exudate addition was highest in grassland soil, intermediate in fixed dune and lowest in mobile dune soil. However, the proportion of native soil carbon mineralized was highest in mobile dune soil, reflecting the low C/N ratio found there. The exudate effects on CO2-C emissions and other variables differed somewhat between biotopes, but total respiration(including that from the added substrates) was significantly increased in all combinations compared with the control, except for oxalic acid addition to mobile dune soil, which reduced CO2-C emissions from native soil carbon. A small but statistically significant increase in pH by the exudate additions in grassland and fixed dune soil was observed, but there was a major decrease from acid additions to mobile dune soil. In contrast, electrical conductivity decreased in grassland and fixed dune soil and increased in mobile dune. Thus, discrete components of root exudates affected soil environmental conditions differently, and responses to root exudates in soils with low carbon contents can differ from those in normal soils. The results indicate a potential for, e.g., acid root exudates to decrease decomposition rate of soil organic matter in low carbon soils, which is of interest for both soil restoration and carbon sequestration. | YongQing LUO XueYong ZHAO Olof ANDRéN YangChun ZHU WenDa HUANG | 2014 | Journal of Arid Land2014，6，4： | 11 |
| 3 | Inhibitory effect of Salicornia europaea on the marine alga Skeletonema costatum显示文摘Exploiting the negative biochemical interference between plants and algal species has been suggested as a method to control harmful algal blooms.In this work,we investigated the inhibitory effect of the salt marsh halophyte Salicornia europaea against the marine alga Skeletonema costatum.S.europaea suppressed the growth of S.costatum in a nutrient-sufficient co-culture system,indicating that the inhibition of algal growth was because of the phytotoxic effect of S.europaea,rather than nutrient competition.We tested aqueous and organic extracts from S.europaea roots against S.costatum.The organic extracts inhibited growth and affected the cell size and chlorophyll a content of S.costatum in a dose-dependent manner.Among the three tested organic extracts,the methanol extract had the greatest effects on S.costatum,followed by butanol extract,and then the chloroform extract.Two flavonoids,rutin and quercetin-3-D-glucoside,were identified in the methanol extract by high performance liquid chromatography.The concentration of rutin was much higher than that of quercetin-3-D-glucoside.In an algal bioassay,rutin inhibited the growth of S.costatum and the inhibitory effect increased with increasing rutin concentration and with decreasing initial algal density.Therefore,we concluded that S.europaea negatively affects the growth of S.costatum,and that rutin,a metabolite of S.europaea,may play a role in this inhibitory effect. | JIANG Dan HUANG LingFeng LIN YongQing NIE LingLing LV SuLian KUANG TingYun LI YinXin | 2012 | Science China(Life Sciences)2012，55，6： | 8 |
| 4 | Zircon SHRIMP U-Pb geochronology,geochemistry and petrogenesis of the upper Eocene Shuangmaidi peraluminous granite in Baoshan Block,Western Yunnan Terrain,southwestern China显示文摘The Baoshan Block is tectonically located in the middle segment of the Sibumasu plate.Granitic magmatism within the Baoshan Block has been considered weakly active due mainly to very limited exposures during the Himalaya orogenic episode.The geochronological study on the buried Shuangmaidi granite has confirmed the existence of the Cenozoic granitoids in the Baoshan Block.The present study indicates that:(1) It is medium-to coarse-grained two mica phyric granite,characterized by high SiO 2 (73.55%-77.16%) and low CaO (0.34%-1.38%) contents,with a total alkalis (K 2 O+Na 2 O) of 5.22%-8.03%,K 2 O/Na 2 O ratios of 0.24-1.79,and total rare earth elements (ΣREE) of the granite between 85 and 125 ppb.All samples are enriched in light REE and exhibit medium negative Eu anomalies;and they show pronounced negative anomalies in Ba,Sr,Ti,and Nb but significant positive anomalies in K,Rb,U,Th,and Pb on mantle-normalized trace element patterns,indicating typi-cally peraluminous to strongly peraluminous S-type granite.(2) The zircon SHRIMP U-Pb ages of the granite are 36.27±0.48 Ma for the samples from ZK7-1 and 35.78±0.49 Ma for those from ZK0-1,respectively.The similar zircon ages from these two drill cores may suggest that the granite samples come from the same buried pluton.(3) 206 Pb/204 Pb values of the granite vary from 20.115 to 25.359,207 Pb/204 Pb from 15.776 to 16.160,and 208 Pb/204 Pb from 39.236 to 41.285,showing the characteristics of radio-active lead anomaly of the upper crust.The (87 Sr/86 Sr) i values calculated on the average age of the two-mica orthoclase granite (36 Ma) range from 0.72524 to 0.77503 and ε Nd (t) values vary from 10.9 to 11.7.These data,along with the depleted-mantle Nd modal ages of 1.73-1.80 Ga,imply that the granites might have formed from partial melting of the Precambrian crystal basements.(4) On the Hf-Rb-Ta diagram,almost all the samples fall within the field of post-collision tectonic setting.The CaO/Na 2 O and Al 2 O 3/TiO 2 ratios suggest that the granitic magma may have formed from partial melting of clay-rich crustal materials with a pos-sible melting temperature of about 900°C and a possible crystallization temperature of 775-795°C.(5) During the post-collision of the Himalaya orogen,with the southeastward extrusion of the Indochina continent resulting from the continuous northward indentation of the India continent into the Asia,the Gaoligong Fault,as the western boundary of the Indochina continent,moved in the dextral strike-slip on a large scale to trigger partial melting of the thickened crust,and the peraluminous granitic magma from which the Shuangmaidi two-mica orthoclase granite derived was formed. | HUANG JingNing CHEN YongQing ZHAI XiaoMing LU YingXiang XIE YongFu CHENG ZhiZhong | 2011 | Science China Earth Sciences2011，54，7： | 7 |
| 5 | Factors regulating population dynamics of the amphipod Ampithoe valida in a eutrophic subtropical coastal lagoon显示文摘Year-round investigations were carried out to address the population dynamics of amphipod Ampithoe valida and its potential regulating factors in the Yundang Lagoon (a eutrophic subtropical coastal lagoon in Xiamen City, China) from October 2007 to October 2008. The results show that A. valida population was largely composed of juveniles and reached a peak abundance (12.02 × 10 3 ind./m2 ) in March, but sharply shrunk in July. The monthly variation pattern of A. valida seemed to follow that of Ulva lactuca which is the main food resource for A. valida, indicating a strong influence of food availability on A. valida population dynamics. Life cycle studies in laboratory indicate that A. valida adopted an r-selected life strategy, e.g., rapid growth rate (0.216-0.302 mm/d), consecutive breeding (4-10 times), short reproductive rhythm (9-17 d) and huge fecundity (24-192 eggs or 6-94 juveniles per brood), which contributed to the fast population growth of A. valida from January to March. Although temperature may also be a significant cause, A. valida could grow quickly and show normal reproductive traits (i.e., the timing of sexual differentiation or maturity, the reproductive rhythm, the number of broods all through its lifespan and offspring production) in temperature between 15-30 C. Therefore, the temperature variation in the lagoon water should not account for the sharp variation of A. valida population by affecting the survival, growth and reproduction of the amphipod. However, negative correlation between water temperature and U. lactuca biomass in the lagoon suggested that temperature could have indirectly affected the population dynamics of A. valida by affecting its food availability. The authors conclude that, in the Yundang Lagoon, the population dynamics of A. valida was mainly controlled by the food availability rather than water temperature. | ZHENG Xinqing HUANG Lingfeng HUANG Bangqin LIN Yongqing | 2013 | Acta Oceanologica Sinica2013，32，6： | 5 |
| 6 | Regulation of histone demethylase KDM6B by hypoxia-inducible factor-2α显示文摘离氨酸(K) 特定的 demethylase 6B (KDM6B ) 是 histone H3K27 demethylase,它明确地催化 H3 lysine-27 tri/dimethylation (H3K27me3/2 ) 的 demethylation。KDM6B 能由支持与 RNA 聚合酶 II 和相关延伸因素被联系的 transcriptional 延伸激活基因抄写。KDM6B 因此为基因表示的规定是重要的。以前的研究显示了象 KDM3A, KDM4B,和 KDM4C 那样的几 histone demethylases 被组织缺氧可诱导的因素(HIF ) 调整。但是, KDM6B 上的组织缺氧的效果充分没被理解。在这研究,我们发现 KDM6B mRNA 和蛋白质的表示层次在组织缺氧下面是平常地起来调整的(1% O 2) 或模仿组织缺氧(desferrioxamine mesylate 或 CoCl 2 处理)(P < 0.05 ) 。RNAi 的结果证明 KDM6B 的起来规定依赖于 HIF-2,然而并非在 HIF-1 上。染色质 immunoprecipitation 试金的结果显示在 KDM6B 倡导者(4041 ~ 4037 ) 有一个组织缺氧反应元素。Co-IP 试金的结果显示 KDM6B 能与 HIF-2 或 HIF-1 形成建筑群。击倒的实验暗示 KDM6B 是为 HIF-2 目标基因的一个潜在的管理者。这些数据证明 KDM6B 是 HIF-2 调整的新组织缺氧反应基因。我们的结果也证明 KDM6B 是 HIF- 的潜在的激活剂,它为组织缺氧反应基因的激活是重要的。 | Xiaoqiang Guo Zha ntao Tian Xuliang Wang Shuhong Pan Weiren Huang Yongqing Shen Yaoting Gui Xianglin Duan Zhiming Cai | 2015 | Acta Biochimica et Biophysica Sinica2015，47，2： | 5 |
| 7 | Telescoping ore targets by geochemical exploration at multiple scales in Eastern Yunnan Pt geochemical province,southwestern China显示文摘Platinum has been one of the highly needed mineral resources in China.The geochemical exploration at two survey scales was applied in telescoping ore targets for the first time in Eastern Yunnan Pt geochemical province that was delineated using Pt data from flood plain sediments with extra-low sampling density.Our study was based on the delineations and assessments of both regional and local Pt anomalies using the Pt data by analyzing with C-OES the composite samples with two sampling densities.The composite samples were obtained by recomposing at two sampling densities the original stream sediment samples collected by the National Geochemical Mapping Project.Semivariograms were used to quantitatively describe the variability of Pt anomalies and further analyze the factors controlling the variability.Pt resource potentials of both the regional Pt anomalies and the local Pt anomalies in the study area were estimated based on the geochemical block methods,respectively.It comes to the conclusions as follows.(1) From the regional to local Pt anomaly,the factors controlling their variability from the deep seated faults-basalts turn into the basalts-branch faults,which suggest that Semivariograms could identify the geological factors controlling the variability of the Pt anomalies identified by the Pt data from the stream sediments with different sampling densities.(2) There exist two types of Pt anomalies in the study area.One is those displaying at sampling densities,and its average Pt concentration significantly increases with sampling density increasing.The other is getting weaker and/or disappears with sampling density increasing.This shows that TOTGEMS could gradu-ally eliminate non-ore anomalies and keep ore anomalies.(3) The average Pt concentration of the local Pt anomaly blocks delineated using Pt data from stream sediments with sampling density of one composite per 16 km2 is twice as much as that of the regional Pt anomaly blocks delineated using Pt data from stream sediments with sampling density of one composite per 64 km2.The Pt resource amount of the local Pt anomaly blocks is 60% of the regional anomaly blocks,but the area of the former is just 35% of the latter,which suggests that the Pt resource amount is mainly concentrated in its local anomalies,and that TOTGEMS has a good exploration function that efficiently approaches ore targets. | CHEN YongQing HUANG JingNing ZHAI XiaoMing ZHAO BinBin | 2009 | Science China Earth Sciences2009，52，5： | 3 |

| 10 | Numerical studies on flow and thermal fields in MOCVD reactor显示文摘A systematic study has been performed to investigate the flow and thermal patterns of vertical rotating Thomas Swan MOCVD reactor at low pressure,using 2-D dynamic modeling.By varying and calculating the several important process parameters of the reactor,the optimized conditions of the uniform distributions of velocity and temperature profiles in steady state have been obtained.Then,time-dependent models with the step response perturbation of the total gas rate can help identify the visual transient behavior inside the reactor and analyze the mechanism of delay time,relaxation oscillation and pulsative oscillation.These results are beneficial to the process parameter optimization and geometrical configuration design of the MOCVD reactor. | ZHONG ShuQuan REN XiaoMin HUANG YongQing WANG Qi HUANG Hui | 2010 | Chinese Science Bulletin2010，55，6： | 2 |
| 11 | Failure characteristics of Ag-SnO_2 contact material in AC level显示文摘The failure characteristics of the contact material Ag-SnO2 were investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM),and X-ray energy dispersive spectroscopy(EDS).Phase analysis showed that there were Ag,SnO2,and Sn on the contact surfaces at the time of failure under the load condition of 30 A and 220 V(AC),which means that SnO2 decomposed in service.When the contacts were tested under airproof ambient condition,half-spherical bulges came into being on the contact surfaces,which resulted in early failure and dispersive characteristics.But half-spherical bulges were not found when the contacts were tested under open ambient condition.The temperature change of the contacts during the life testing under airproof ambient condition was different from that under open ambient condition. | MENG Fanbin LU Jianguo ZHU Yongqing LU Ningyi CHEN Zhichao HUANG Qiutao | 2008 | Rare Metals2008，27，1： | 2 |
| 12 | Deformation mechanisms in aβ-quenched Ti-5321 alloy:In-situ investigation related to slip activity,orientation evolution and stress induced martensite显示文摘The deformation behavior ofβ-quenched nearβTi-5321(Ti-5Al-3Mo-3V-2Cr-2Zr-1Nb-1Fe)alloy was systematically studied using in-situ tensile test monitored by the scanning electron microscopy(SEM).Besides,the electron backscatter diffraction(EBSD)was performed to thoroughly discuss the deformation mechanisms.The results indicated that slip activities,crystal rotation and stress induced martensite transformation were the major deformation mechanisms in theβ-quenched Ti-5321 alloy during in-situ tensile testing.The slip activities were investigated by using the EBSD-trace analysis,which demonstrated that{110}<111>,{112}<111>and{123}<111>slip systems were activated and the{110}<111>slip system dominated.Besides,βgrains rotated about 7.8°to accommodate the increased macrostrain.Notably,the stress induced martensiteα″which was related to the double yielding behavior during tensile process exhibited multiple characteristics.The differentα″variants divided theβmatrix into smallerβblocks with a typical zigzag morphology,in which oneα″variant passed through another one by deflecting its initial growth direction.Moreover,the deformation twinning in martensiteα″and slip bands cutting through martensiteα″effectively accommodated the local strain.These systematically analysis can provide insightful information about the deformation mechanisms in nearβtitanium alloys. | Cong Wu Qinyang Zhao Shixing Huang Yongqing Zhao Lei Lei Junqiang Ren Qiaoyan Sun Lian Zhou | 2022 | Journal of Materials Science & Technology2022，，17： | 2 |
| 13 | Isolation and characterization of a thermophilic Bacillus shackletonii K5 from a biotrickling filter for the production of polyhydroxybutyrate显示文摘Polyhydroxyalkanoates(PHAs) are aliphatic polyesters accumulated intracellularly by both Gram-negative and Gram-positive bacteria. However, compared to the PHAs of Gramnegative bacteria, few endotoxins(lipopolysaccharides, LPS), which would be co-purified with PHAs and cause immunogenic reactions, are found in the PHAs produced by Gram-positive bacteria. A thermophilic Gram-positive bacterium K5, which exhibited good growth and polyhydroxybutyrate(PHB)-accumulating ability, has been isolated and characterized from a biotrickling filter designed for the removal of NOx from flue gas in a coal-fired power plant in China. Based on the biochemical characterization and 16 S rRNA gene sequence(Genbank accession no. JX437933), the strain K5 has been identified as Bacillus shackletonii, which has rarely been reported in the literature, and this report is the first time that B. shackletonii has been found to accumulate PHB. The strain K5 was able to utilize glucose as carbon source to synthesize PHB at a broad range of temperatures(from 35 to 50 °C), and the ideal temperature was 45 °C. The strain K5 could effectively yield PHB of up to 69.9% of its cell dry weight(CDW)(2.28 g/L) in flask experiments employing glucose as carbon source at 45 °C, followed by 56.8% and 52.3% of its CDW when using sodium succinate and glycerol as carbon source, respectively. For batch cultivation, the strain K5 was able to produce PHB of up to 72.6% of its cell dry weight(9.76 g/L) employing glucose as carbon source at 45 °C and pH 7.0. | Yong Liu Shaobin Huang Yongqing Zhang Fuqian Xu | 2014 | Journal of Environmental Sciences2014，26，7： | 2 |

| 15 | Electronic structure of exfoliated millimeter-sized monolayer WSe2 on silicon wafer显示文摘The mono layer WSe2 is in teresting and important for future application in nanoelectronics,spintronics and valleytronics devices,because it has the largest spin splitting and Ion gest valley coherence time among all the known monolayer transition-metal dichalcogenides(TMDs).Toobtain the large-area monolayer TMDs'crystal is the first step to manu facture scalable and high-performance electronic devices.In this letter,we have successfully fabricated millimeter-sized mono layer WSe2 single crystals with very high quality,based on our improved mecha nicalexfoliation method.With such superior samples,using standard high resolution angle-resolved photoemission spectroscopy,we didcomprehe nsive electronic band structure measurements on our mono layer WSe2.The overall band features point it to be a 1.2 eV direct bandgap semico nductor.Its spin splitting of the valence band at K point is found as 460 meV,which is 30 meV less than the corresponding band splitting in its bulk counterpart.The effective hole masses of valence bands are determined as 2.344 me atГ,and 0.529 me as well as 0.532 meat K for the upper and lower branch of splitting ban ds,respectively.And screening effect from substrate is shown to substa ntially impact onthe electronic properties.Our results provide importa nt insights into band structure engineering in mono layer TMDs.Our mono layer WSe2 crystals may constitute a valuable device platform. | Wenjuan Zhao Yuan Huang Cheng Shen Cong Li Yongqing Cai Yu Xu Hongtao Rong Qiang Gao Yang Wang Lin Zhao Lihong Bao Qingyan Wang Guangyu Zhang Hongjun Gao Zuyan Xu Xingjiang Zhou Guodong Liu | 2019 | Nano Research2019，12，12： | 2 |

| 18 | Emergence of superconductivity from fully incoherent normal state in an iron-based superconductor (Ba_(0.6)K_(0.4))Fe_2As_2显示文摘In unconventional superconductors, it is generally believed that understanding the physical properties of the normal state is a pre-requisite for understanding the superconductivity mechanism. In conventional superconductors like niobium or lead, the normal state is a Fermi liquid with a well-defined Fermi surface and well-defined quasipartcles along the Fermi surface. Superconductivity is realized in this case by the Fermi surface instability in the superconducting state and the formation and condensation of the electron pairs(Cooper pairing). The high temperature cuprate superconductors, on the other hand, represent another extreme case that superconductivity can be realized in the underdoped region where there is neither well-defined Fermi surface due to the pseudogap formation nor quasiparticles near the antinodal regions in the normal state. Here we report a novel scenario that superconductivity is realized in a system with well-defined Fermi surface but without quasiparticles along the Fermi surface in the normal state.High resolution laser-based angle-resolved photoemission measurements have been performed on an optimally-doped iron-based superconductor(Ba_(0.6)K_(0.4))Fe_2As_2. We find that, while sharp superconducting coherence peaks emerge in the superconducting state on the hole-like Fermi surface sheets, no quasiparticle peak is present in the normal state. Its electronic behaviours deviate strongly from a Fermi liquid system. The superconducting gap of such a system exhibits an unusual temperature dependence that it is nearly a constant in the superconducting state and abruptly closes at Tc. These observations have provided a new platform to study unconventional superconductivity in a non-Fermi liquid system. | Jianwei Huang Lin Zhao Cong Li Qiang Gao Jing Liu Yong Hu Yu Xu Yongqing Cai Dingsong Wu Ying Ding Cheng Hu Huaxue Zhou Xiaoli Dong Guodong Liu Qingyan Wang Shenjin Zhang Zhimin Wang Fengfeng Zhang Feng Yang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou | 2019 | Science Bulletin2019，64，1： | 1 |
