| 1 | Polyacrylic acid sodium salt film entrapped Ag-nanocubes as molecule traps for SERS detection显示文摘提高表面的拉曼光谱学(重量的单位) 是为踪迹化学药品的一种快分析技术;然而,吸附 analytes 要求活跃重量的单位底层,因此为底层与需要的亲密关系限制目标种类到那些。这里我们现在的联网的 polyacrylic 酸钠盐(PAAS ) 电影骗诱 Ag-nanocubes (作为 Ag-nanocubes@PAAS 表示了) 作为为有或没有高亲密关系的 analytes 的有效重量的单位底层。一次 analyte 水的答案在干燥 Ag-nanocubes@PAAS 底层上被扔,嗜酒的 PAAS 变得肿强迫 Ag-nanocubes 松开,当时在在 Ag-nanocubes 之中的空隙弥漫的 analytes。当弄干时, PAAS 缩小并且拉 Ag-nanocubes 回到他们的以前的聚集的状态,当 PAAS 网络为重量的单位察觉在在 Ag-nanocubes 之间的小差距耽搁 analytes 时。没有强壮的亲密关系,策略为 Ag 为不仅 singleanalytes 而且 multi-analytes 被证明有效,在环境在能吸附、非能吸附的污染物质的基于重量的单位的同时的 multi-analyte 察觉显示出它的潜力。 | Zhulin Huang Guowen Meng Qing Huang Bin Chen Fei Zhou Xiaoye Hu Yiwu Qian Haibin Tang Fangming Han Zhaoqin Chu | 2014 | Nano Research2014，7，8： | 6 |
| 2 | Direct Observation of the Strong Interaction Between Carbon Nanotubes and Quartz Substrate显示文摘We present a chemical vapor deposition(CVD)method for the growth of uniform single-walled carbon nanotube(SWNT)arrays on a stable temperature(ST)-cut single crystal quartz substrate using a mixture of methanol and ethanol as carbon source.It is found that introducing methanol during the growth can improve the density and the length of the well-aligned SWNTs in the arrays as well as increase the SWNT/quartz interaction.Obvious“up-shifts”of G-band frequencies in the Raman spectra have been found for the aligned SWNTs.A well-designed control experiment shows that the G-band“up-shifts”originate from the strong interaction between SWNTs and the quartz substrate.It is believed that exploring this interaction will help to elucidate the growth mechanism;ultimately,this will help realize the promise of controlling the chirality of SWNTs. | Lei Ding Weiwei Zhou Thomas P.McNicholas Jinyong Wang Haibin Chu Yan Li Jie Liu | 2009 | Nano Research2009，2，11： | 4 |
| 3 | Understanding enhancing mechanism of Pr_(6)O_(11) and Pr(OH)_(3) in methanol electrooxidation显示文摘The presence of oxygen vacancies and hydroxyl groups are both favorable for the methanol electrooxidation on Pt-based catalysts.Understanding and differentiating the enhancing mechanism between oxygen vacancies and hydroxyl groups for high activity of Pt catalysts in methanol oxidation reaction(MOR)is essential but still challenging.Herein,we developed two kinds of co-catalyst for Pt/CNTs,Pr_(6)O_(11)is rich in oxygen vacancies but contains substantially no hydroxyl groups,while Pr(OH)_(3) possesses abundant hydroxyl groups without oxygen vacancies.After a seque nce of designed experiments,it can be found that both oxygen vacancies and hydroxyl groups can improve the performance of Pt/CNTs electrocatalysts,but the enhancing mechanism and improving degree of oxygen vacancies and hydroxyl groups for the MOR are different.Since the oxygen vacancies are more conducive to increasing the intrinsic activity of the Pt catalyst,and the hydroxyl groups play a decisive role in dehydrogenation and deproto nation of methanol,the co-catalysts with both oxygen vacancies and hydroxyl groups mixed with Pt/CNTs have higher catalytic performance.Therefore,hydroxyl-rich Pr_(6)O_(11)·xH_(2)O was prepared and used as MOR electrocatalyst after mixed with Pt/CNTs.Benefiting from the synergistic effect of oxygen vacancies and hydroxyl groups,the Pr_(6)O_(11)·xH_(2)O/Pt/CNTs shows a high peak current density of 741 mA/mg,which is three times higher than that of Pt/CNTs.These new discoveries serve as a promising strategy for the rational design of MOR catalysts with low cost and high activity. | Yang Yang Zhenyu Li Ying Yu Xueqiong Zhang Hang Wei Haibin Chu | 2022 | Journal of Rare Earths2022，40，1： | 3 |
| 4 | A Microsatellite Genetic Linkage Map of Black Rockfish(Sebastes schlegeli)显示文摘Ovoviviparous black rockfish(Sebastes schlegeli) is an important marine fish species for aquaculture and fisheries in China. Genetic information of this species is scarce because of the lack of microsatellite markers. In this study, a large number of microsatellite markers of black rockfish were isolated by constructing microsatellite-enriched libraries. Female- and male-specific genetic linkage maps were constructed using 435 microsatellite markers genotyped in a full-sib family of the fish species. The female linkage map contained 140 microsatellite markers, in which 23 linkage groups had a total genetic length of 1334.1 c M and average inter-marker space of 13.3 c M. The male linkage map contained 156 microsatellite markers, in which 25 linkage groups had a total genetic length of 1359.6 c M and average inter-marker distance of 12.4 c M. The genome coverage of the female and male linkage maps was 68.6% and 69.3%, respectively. The female-to-male ratio of the recombination rate was approximately 1.07:1 in adjacent microsatellite markers. This paper presents the first genetic linkage map of microsatellites in black rockfish. The collection of polymorphic markers and sex-specific linkage maps of black rockfish could be useful for further investigations on parental assignment, population genetics, quantitative trait loci mapping, and marker-assisted selection in related breeding programs. | CHU Guannan JIANG Liming HE Yan YU Haiyang WANG Zhigang JIANG Haibin ZHANG Quanqi | 2014 | Journal of Ocean University of China2014，13，6： | 2 |
| 5 | Fluorescence enhancement of Tb^(3+) complexes by adding silica-coated silver nanoparticles显示文摘Six kinds of terbium ternary complexes with halo-benzoic acids were synthesized. Their compositions were determined by C, H elemental analyzer and EDTA titration. The infrared spectra, ultraviolet absorption spectra, and fluorescence spectra were also measured to identify the complexes. Elemental analysis showed that the compositions of these complexes were Tb(p-Br BA)3?H2O, Tb(p-Cl BA)3?2H2O, Tb(p-FBA)3?H2O, Tb(o-FBA)3?2H2O, Tb(o-Cl BA)3?H2O, and Tb(o-Br BA)3?H2O, respectively. The monodispersed Ag@Si O2 core-shell nanoparticles with silica thicknesses of 10, 15, and 25 nm were successfully prepared and characterized by transmission-electron microscopy. Fluorescence intensities of the complexes were detected before and after Ag@Si O2 core-shell nanoparticles were added; the enhancement times were related to the silica-shell thickness. The fluorescence enhancement times were largest when the thickness of the silica shell was 25 nm. The mechanism may be attributed to the localized surface-plasmon resonance. Furthermore, the enhancement effect of terbium fluoro-benzoate complexes was the strongest in these complexes. This result may be attributed to the hydrogen bond between the hydroxyl on the surface of the silica shell and the fluorine atom. | Dan Zhou Xuemei Lin Ailing Wang Jingjing Li Yanrong Qu Haibin Chu Yongliang Zhao | 2015 | Science China Chemistry2015，58，6： | 2 |
| 6 | Inorganic Hierarchical Nanostructures Induced by Concentration Difference and Gradient显示文摘A very simple strategy for preparing hierarchical inorganic nanostructures under ambient aqueous conditions is presented.The hierarchical inorganic nanomaterials were obtained by simply adding a highly concentrated solution of one reactant to a solution of another reactant with low concentration.No surface-capping molecules or structure-directing templates were needed.The preparation of hierarchical single crystalline PbMoO4 was used as an example in order to study the effects of varying the reaction conditions and the mechanism of the process.It was found that the large concentration difference(typically in excess of 200-fold)and the concentration gradient of the reactants both play key roles in controlling the diffusion process and the morphology of the resulting nanostructures.This kinetically controlled strategy is facile and is easily adapted to prepare a variety of inorganic materials. | Haibin Chu Xuemei Li Guangda Chen Zhong Jin Yan Zhang Yan Li | 2008 | Nano Research2008，1，3： | 1 |
| 7 | Roles of hydroxyl and oxygen vacancy of CeO_(2)·xH_(2)O in Pd-catalyzed ethanol electro-oxidation显示文摘In the field of noble metal-catalyzed alcohol electro-oxidation reaction(AOR),huge attention is paid on the composition,size,facet,and structure of the metals,while the support engineering should also be emphasized.CeO_(2)has been widely used as a unique support in AOR,primarily due to its abundant oxygen vacancies(O_(v)).Herein,we report CeO_(2)·xH_(2)O nanoparticles with both massive hydroxyl groups(OH)and O_(v)remarkably enhance the catalytic activity and stability of Pd toward ethanol oxidation reaction(EOR).The CO striping experiments and density functional theory(DFT)calculations suggest that OH and O_(v)on CeO_(2)·xH_(2)O surface bring about a large downshift of Pd d-band center and a significant weakening of CO absorption on Pd.Moreover,OH and O_(v)also play synergic roles in the removal of toxic intermediates.Consequently,the important roles of OH and O_(v)of CeO_(2)·xH_(2)O are confirmed in Pd-catalyzed EOR.The facile CeO_(2)·xH_(2)O-enhanced strategy can contribute to the catalyst design for other energy conversion reactions. | Zhenyu Li Jiefei Li Zexuan Zheng Kunhong Jiang Tianrun Zheng Dongmin Wang Hang Wei Zhiming Shi Xiaotian Li Haibin Chu | 2022 | Science China Chemistry2022，65，5： | 1 |
| 8 | Effect of Sweet Corn Straw Returning to the Field on Soil Fertility, Yield and Benefit显示文摘It is an important way for realizing sustainable development of sweet corn production to stabilize and improve soil fertility of cultivated land in sweet corn production region.Through the test of sweet corn straw directly returning to the field after 6seasons for 3years,the results showed that continuous single application of chemical fertilizer is not conducive to the stability of soil fertility and yield improvement,and implementation of straw returning could receive fertility,improve soil acidic conditions,and enhance the yield of sweet corn.Compared with before the test,the single application of chemical fertilizer increased soil available phosphorus,while the contents of soil organic matter,available nitrogen and available potassium decreased by 1.08,1.18 and 2.47mg/kg respectively,and the soil pH decreased by 0.15.Under the same fertilizer conditions,organic matter contents of single and double-season straw returning increased by 0.71 and 1.29g/kg,available nitrogen increased by 17.15 and 28.27mg/kg,available phosphorus increased by 0.96 and 1.73mg/kg,available potassium increased by 2.41 and 5.92mg/kg,the soil pH increased by 0.16 and 0.2.Compared with the single application of chemical fertilizer,the average yields of single and double-season straw returning increased by 7.5%and 11.8%,and their average income increased by 87.3and 117.1yuan of per mu(667m^2)respectively. | Peng Wangdong Chu Chengxing Zhong Yaqing Lai Weihong Zhang Haibin Huang Liuyu Shi Xiaoxiao Wei Jialiang | 2016 | Meteorological and Environmental Research2016，7，4： | 1 |
| 9 | Preparation and properties of CdS/Au composite nanorods and hollow Au tubes显示文摘1-dimensional (1D) metal-semiconductor nano-scale composite superstructures based on Au nanoparticles and CdS nanorods were prepared.The outer surface of CdS nanorods was modified with mercapto-ethylamine (MEA) in advance.With the aid of MEA,dense and uniform Au nanoparticles were deposited onto the external wall of CdS nanorods through in situ chemical reduction of AuCl4-ions.Those Au nanoparticles induced further electroless deposition and a continuous layer of Au was formed on CdS nanorods.Stable hollow Au tubes were obtained after the inner CdS cores were etched by HCl.UV-Vis,FL,XPS,EDX,TEM and SEM measurements were carried out to characterize the produced materials.The quenching of the defect emission of CdS in CdS-nanorod/Au-nanoparticle hybrid superstructures was detected,which was ascribed to the energy transfer from the exciton of CdS to surface plasma resonance level of Au. | YANG ZhaoHui CHU HaiBin JIN Zhong ZHOU WeiWei LI Yan | 2010 | Chinese Science Bulletin2010，55，10： | 1 |
