| 1 | Mechanism of Cu(Ⅱ) adsorption inhibition on biochar by its aging process显示文摘Biochar exposed in the environment may experience a series of surface changes, which is called biochar aging. In order to study the effects of biochar aging on Cu(II) adsorption, we analyzed the surface properties before and after biochar aging with scanning electron microscopy(SEM) coupled to an energy-dispersive X-ray spectrometer(EDX) and diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS), and then explored the influence of the aging process on Cu(II) adsorption by batch experiments. After the aging process, the oxygen concentration, phenolic hydroxyl groups, aromatic ethers and other oxygen-containing functional groups on the biochar surface increased, while carboxyl groups slightly decreased. Thus, over a range of pH, the cation exchange capacity(CEC) and adsorption capacity of Cu(II) on the aged biochar were smaller than those of new biochar,indicating that when biochar is incubated at constant temperature and water holding capacity in the dark, the aging process may inhibit Cu(II) adsorption. Meanwhile, the dissociation characteristics of oxygen-containing functional groups changed through the aging process, which may be the mechanism by which the biochar aging process inhibits the Cu(II) adsorption. Carboxyl groups became more easily dissociated at low pH(3.3–5.0),and the variation of maximum adsorption capability(qm) of Cu(II) on the old biochar was enlarged. Phenolic hydroxyl groups increased after the aging, making them and carboxyl groups more difficult to dissociate at high pH(5.0–6.8), and the variation of qmof Cu(II) on the aged biochar was reduced. | Yue Guo Wei Tang Jinggui Wu Zhaoqin Huang Jingyu Dai | 2014 | Journal of Environmental Sciences2014,26,10: | 21 |
| 2 | Collagen-binding basic fibroblast growth factor improves functional remodeling of scarred endometrium in uterine infertile women: a pilot study显示文摘Intrauterine adhesion(IUA) is a common cause of uterine infertility and one of the most severe clinical features is endometrial fibrosis namely endometrial scarring for which there are few cures currently. Blocked angiogenesis is the main pathological change in the scarred endometrium. The fibroblast growth factor 2(b FGF), a member of FGF family, is usually applied to promote healing of refractory ulcer and contributes to angiogenesis of tissues. In this study, the sustained-release system of b FGF100 μg was administrated around scarred endometrium guiding by ultrasound every 4 weeks in 18 patients(2–4 times). Results showed that after treatment, the menstrual blood volume, endometrial thickness and the scarred endometrial area were improved.Histological study showed blood vessel density increased obviously. Three patients(3/18) achieved pregnancy over 20 gestational weeks. Therefore, administrating the b FGF surrounding scarred endometrium may provide a new therapeutic approach for the patients with endometrial fibrosis. | Peipei Jiang Xiaoqiu Tang Huiyan Wang Chenyan Dai Jing Su Hui Zhu Minmin Song Jingyu Liu Ziqing Nan Tong Ru Yaling Li Jingmei Wang Jun Yang Bing Chen Jianwu Dai Yali Hu | 2019 | Science China(Life Sciences)2019,62,12: | 16 |
| 3 | Improved genetic algorithm for nonlinear programming problems显示文摘An improved genetic algorithm(IGA) based on a novel selection strategy to handle nonlinear programming problems is proposed.Each individual in selection process is represented as a three-dimensional feature vector which is composed of objective function value,the degree of constraints violations and the number of constraints violations.It is easy to distinguish excellent individuals from general individuals by using an individuals' feature vector.Additionally,a local search(LS) process is incorporated into selection operation so as to find feasible solutions located in the neighboring areas of some infeasible solutions.The combination of IGA and LS should offer the advantage of both the quality of solutions and diversity of solutions.Experimental results over a set of benchmark problems demonstrate that IGA has better performance than other algorithms. | Kezong Tang Jingyu Yang Haiyan Chen Shang Gao | 2011 | Journal of Systems Engineering and Electronics2011,22,3: | 8 |
| 4 | Crystal structures and thermal decomposition kinetics of lanthanide complexes with 3,4,5-trimethoxybenzoic acid and 1,10-phenanthroline显示文摘A series of lanthanide complexes with the 3,4,5-trimethoxybenzoic acid(3,4,5-tmoba) and 1,10-phenanthroline(phen),[Ln(3,4,5-tmoba) 3 phen] 2(Ln = Pr(1),Nd(2) and Ho(3)),have been synthesized and characterized by a series of techniques including elemental analysis,IR spectra,X-ray crystallography and TG/DSC-FTIR technology.The three complexes have two kinds of coordination modes,in which the Pr 3+ and Nd 3+ cations are nine-coordinated and the Ho 3+ cation is eight-coordinated.The three-dimensional IR accumulation spectra of gaseous products for complexes 1-3 were analyzed and the gaseous products were identified by the typical IR spectra obtained from the 3D surface graphs.Meanwhile,we obtained the activation energy E of the first steps of complexes 1-3 by the integral isoconversional non-linear(NL-INT) method and discussed the non-isothermal kinetics of complexes 1-3 using the Malek method.Finally,SB(m,n) was defined as the kinetic method of the first-step thermal decomposition.The thermodynamic parameters △G≠,△H≠ and △S≠ of activation at the peak temperature were also calculated. | TANG Kun ZHANG JianJun REN Ning ZHENG JunRu LIU JingYu WU KeZhong | 2012 | Science China Chemistry2012,55,7: | 6 |
| 5 | The effects of air temperature and precipitation on the net primary productivity in China during the early 21st century显示文摘Research on how terrestrial ecosystems respond to climate change can reveal the complex interactions between vegetation and climate,net primary productivity (NPP),an important vegetation parameter and ecological indicator,fluctuates within any given ecological environment or regional carbon budget.In this study, spatial interpolation was used to generate a spatial dataset, with 1-km spatial resolution,with meteorological data from 736 observation stations across China.An improved CASA model was used to simulate NPP over the period of 2001-2013 by taking into account land-cover change in every year during the same period.We propose the grid- based spatial patterns and dynamics of annual NPP,annual average temperature,and annual total precipitation based on the model.We also used the model to demonstrate the spatial correlation between NPP,temperature,and pre- cipitation in the study area with special focus on the impact of climate change in the early 21st century.Results showed that the spatial pattern of NPP over all of China is characterized by higher values in the southeast and lower values in the northwest.The spatial pattern of temperature indicates substantial latitudinal differences across the country,and the spatial pattem of precipitation shows a ribbon of decline from the southeast coast to the northwest inland.Most areas show an upward trend in NPP. Temperatures appear to decrease across the country during the global warming hiatus (1998-2008),and are accom- panied by an increase in precipitation over most regions.The correlation between NPP and annual average temperature is weak.Alternatively,NPP and annual total precipitation are positively correlated in northern and central China at a coefficient above 0.64(p <0.01)yet negatively correlated in the eastem parts of the Qinghai- Tibet Plateau and Sichuan Basin.Results can provide useful information for improving parameters for calibra- tion of the terrestrial ecosystem process model. | Qianfeng WANG Jingyu ZENG Song LENG Bingxiong FAN Jia TANG Cong JIANGs Yi HUANG Qing ZHANG Yanping QU Wnlin WANG Wei SHUI | 2018 | Frontiers of Earth Science2018,12,4: | 6 |
| 6 | Terahertz wavefront shaping with multi-channel polarization conversion based on all-dielectric metasurface显示文摘Polarization manipulation of electromagnetic wave or polarization multiplexed beam shaping based on metasurfaces has been reported in various frequency bands.However,it is difficult to shape the beam with multi-channel polarization conversion in a single metasurface.Here,we propose a new method for terahertz wavefront shaping with multi-channel polarization conversion via all-silicon metasurface,which is based on the linear shape birefringence effect in spatially interleaved anisotropic meta-atoms.By superimposing the eigen-and non-eigen-polarization responses of the two kinds of meta-atoms,we demonstrate the possibility for high-efficiency evolution of several typical polarization states with two independent channels for linearly polarized waves.The measured polarization conversion efficiency is higher than 70%in the range of 0.9–1.3 THz,with a peak value of 89.2%at 1.1 THz.In addition,when more other polarization states are incident,combined with the integration of sub-arrays,we can get more channels for both polarization conversion and beam shaping.Simulated and experimental results verify the feasibility of this method.The proposed method provides a new idea for the design of terahertz multi-functional metadevices. | JIE LI CHENGLONG ZHENG JITAO LI GUOCUI WANG JINGYU LIU ZHEN YUE XUANRUO HAO YUE YANG FUYU LI TINGTING TANG YATING ZHANG YAN ZHANG JIANQUAN YAO | 2021 | Photonics Research2021,9,10: | 5 |

| 9 | Ore-forming elements diffusion and distribution in the altered host rock surrounding the Koktokay No.3 pegmatite in the Chinese Altay显示文摘Petrography and geochemistry of the altered and unaltered host rocks surrounding the Koktokay No.3 pegmatite revealed that the unaltered amphibolite is mainly composed of hornblende, plagioclase, and ilmenite.Beyond these primary components, the altered host rocks contain a few newly formed minerals, including biotite,tourmaline, chlorine, and muscovite. The alteration zone surrounding the Koktokay No.3 pegmatite is limited to 2.0 m, characterized by biotitization, tourmalization, and chloritization. In the altered host rocks, the contents of SiO_2, MgO, MnO, Na_2O, and TiO_2 did not vary greatly.However, Al_2O_3 showed a weak decreasing trend with the increasing distance from the pegmatite contact zone, while Fe_2O_3 and CaO showed an increasing trend. The contents of Li, Rb, and Cs in the altered host rocks were much higher than those in the unaltered host rocks, decreasing with distance from the contact. The chondrite-normalized rare earth element(REE) pattern of the altered and unaltered host rock was right-inclined from La to Lu, but enriched in light REEs over heavy REEs after hydrothermal alteration. An isocon plot shows that some oxides migrated in with an order of P_2O_5>K_2O >TiO_2>Al_2O_3>SiO_2>MnO≥MgO, while others migrated out with an order of Na_2O >CaO >Fe_2O_3. For REEs, the migration ratios are positive values withCs >Rb >Li >Nb >Ta >Be, signifying that all REEs migrated from the exsolved magmatic fluid into the altered host rocks. It was concluded that diffusion was the only mechanism for migration of ore-forming elements in the alteration zone. The effective diffusion coefficients(Deff)of LiF, RbF, and CsF were estimated under a fluid temperature of 500–550 °C. Using a function of concentration(C(x,t)) and distance(x), the order of migration distance was determined to be LiF >CsF >RbF, with diffusion times of (3.39 ± 0.35)× 10~6,(3.19 ± 0.28) × 10~5 and(6.33 ± 0.05) × 10~5 years, respectively. | Jingyu Zhao Hui Zhang Yong Tang Zhenghang Lü Yang Chen | 2017 | Acta Geochimica2017,36,2: | 3 |
| 10 | Highly active and sintering-resistant heteroepitaxy of Au nanoparticles on ZnO nanowires for CO oxidation显示文摘Gold was supported on commercial ZnO powders(P) and homemade ZnO nanowires(NWs) by a modified deposition–precipitation method. X-ray diffraction and transmission electron microscopy investigation indicated that the size of the Au nanoparticles(NPs) depended strongly on the calcination temperature.The Au NPs were highly dispersed(< 5 nm) on both supports with calcination temperatures < 400 °C.However, after calcination at 600 °C the Au NPs aggregated much more severely on ZnO P than on ZnO NWs. Gold NPs epitaxially grew into the {10–10} facets of the ZnO NWs after calcination at temperatures > 400 °C. Such unique anchoring mechanism accounts for the much better experimentally observed sintering resistance. X-ray photoelectron spectra showed that Au existed as both metallic Au0 and Auδ+species in all the synthesized catalysts with or without calcination treatment; the ratios of Auδ+/Au0,however, varied, depending on the treatment conditions. Catalytic tests showed that the activity for CO oxidation strongly depended on the size of the Au NPs. After calcination at 600 °C, the specific rate for CO oxidation at room temperature decreased about 30 times on Au/ZnO P but only about 4 times on Au/ZnO NW. Stability tests demonstrated that the Au/ZnO NW catalysts had better stability for CO oxidation. | Jiaxin Liu Botao Qiao Yian Song Hailian Tang Yudong Huang Jingyue(Jimmy) Liu | 2016 | Journal of Energy Chemistry2016,25,3: | 2 |

| 18 | Discovery of New Thioviridamide-Like Compounds with Antitumor Activities显示文摘Thioviridamide is a structurally unique compound with potent antitumor activity.The biosynthesis of thioviridamide follows a typical pathway as ribosomally synthesized and post-transiationally modified peptides,making the genome mining-based discovery of thioviridamide-like compounds rational.Taking advantage of the linkage between the precursor peptide and the metabolite skeleton,we identified a new biosynthetic gene cluster in Streptomyces sp.NRRL S-87 that could encode thioviridamide analogues.Overexpression of the whole gene cluster led to the isolation and structure elucidation of TVA-YJ-4 and TVA-YJ-5,two novel thioviridamide-like compounds featuring N-terminal capping groups.Chemical screening of the fermentation extracts also detected TVA-YJ-6,another new thioviridamide-like compound with representative methionine sulfoxide.Detailed analysis further revealed that these structural modifications were introduced during the compound extraction process instead of through genuine enzymatic reactions.TVA-YJ-4 and TVA-YJ-5 display slightly reduced cytotoxic activities against a panel of tumor cell lines in comparison with their parental natural product,TVA-YJ-2.Our work will expand the membership of this rare class of compounds and promote related biosynthetic studies. | Yuqing Li Jingyu Liu Haoyu Tang Yanping Qiu Dandan Chen Wen Liu | 2019 | Chinese Journal of Chemistry2019,37,10: | 1 |

| 20 | A self-adaptive linear evolutionary algorithm for solving constrained optimization problems显示文摘In many real-world applications of evolutionary algorithms,the fitness of an individual requires a quantitative measure.This paper proposes a self-adaptive linear evolutionary algorithm (ALEA) in which we introduce a novel strategy for evaluating individual's relative strengths and weaknesses.Based on this strategy,searching space of constrained optimization problems with high dimensions for design variables is compressed into two-dimensional performance space in which it is possible to quickly identify 'good' individuals of the performance for a multiobjective optimization application,regardless of original space complexity.This is considered as our main contribution.In addition,the proposed new evolutionary algorithm combines two basic operators with modification in reproduction phase,namely,crossover and mutation.Simulation results over a comprehensive set of benchmark functions show that the proposed strategy is feasible and effective,and provides good performance in terms of uniformity and diversity of solutions. | Kezong TANG Jingyu YANG Shang GAO Tingkai SUN | 2010 | 控制理论与应用(英文版)2010,8,4: | 1 |
