| 1 | Effects of Biochar and Super Absorbent Polymer on Substrate Properties and Water Spinach Growth显示文摘Most previous researches have focused on biochar application in agricultural soils; however, limited information is available concerning the effects of biochar amendment on greenhouse substrate properties. A greenhouse experiment was conducted to investigate effects of wheat straw biochar(0–160 m L L-1) and super absorbent polymer(SAP, 0.8 g L-1) on physical and chemical properties of a substrate based on spent pig litter compost and the growth of water spinach(Ipomoea aquatica Forsk). Total porosity, water-holding capacity, p H and electrical conductivity(EC) of the substrate significantly increased with increasing biochar rates, especially in the substrate without SAP. The values of p H and EC were significantly lower in the substrate with SAP than those without SAP at the high biochar application rates(100–160 m L L-1). The germination rates of water spinach decreased with increasing biochar rates when biochar was added alone(76.9%–83.7%), whereas the rates increased to 83.6%–85.8% when biochar was added in combination with SAP. Growth parameters of water spinach and nutrient uptake by shoots and roots increased with increasing biochar rates and reached the maximum values at the biochar rate of 100 m L L-1. There were significant cubic relationships between the uptake of nutrients(N, P, and K) and biochar rates, both with and without SAP addition. In order to avoid negative effects on plant growth,the biochar application rate should be controlled at an optimal level(100 m L L-1). The SAP addition not only enhanced the positive effects of biochar application on the properties of the substrate, but also inhibited the excessive rise of p H and EC following biochar additions, which led to better plant growth and enhanced nutrient uptakes by water spinach. | FAN Ruqin LUO Jia YAN Shaohua ZHOU Yunlai ZHANG Zhenhua | 2015 | Pedosphere2015，25，5： | 15 |
| 2 | Novel Linear Piezoelectric Motor for Precision Position Stage显示文摘Conventional servomotor and stepping motor face challenges in nanometer positioning stages due to the complex structure, motion transformation mechanism, and slow dynamic response, especially directly driven by linear motor. A new butterfly-shaped linear piezoelectric motor for linear motion is presented. A two-degree precision position stage driven by the proposed linear ultrasonic motor possesses a simple and compact configuration, which makes the system obtain shorter driving chain. Firstly, the working principle of the linear ultrasonic motor is analyzed. The oscillation orbits of two driving feet on the stator are produced successively by using the anti-symmetric and symmetric vibration modes of the piezoelectric composite structure, and the slider pressed on the driving feet can be propelled twice in only one vibration cycle. Then with the derivation of the dynamic equation of the piezoelectric actuator and transient response model, start-upstart-up and settling state characteristics of the proposed linear actuator is investigated theoretically and experimentally, and is applicable to evaluate step resolution of the precision platform driven by the actuator. Moreover the structure of the two-degree position stage system is described and a special precision displacement measurement system is built. Finally, the characteristics of the two-degree position stage are studied. In the closed-loop condition the positioning accuracy of plus or minus <0.5 μm is experimentally obtained for the stage propelled by the piezoelectric motor. A precision position stage based the proposed butterfly-shaped linear piezoelectric is theoretically and experimentally investigated. | CHEN Chao SHI Yunlai ZHANG Jun WANG Junshan | 2016 | Chinese Journal of Mechanical Engineering2016，29，2： | 10 |
| 3 | Tectonic Evolution of the Tianhuan Depression and the Western Margin of the Late Triassic Ordos显示文摘The Ordos Basin is one of the most important oil and gas basins in China. Based on surface outcrop, key exploratory wells and seismic reflection data and by using the technology of 'prototype basin recovery', seismic profile 'layer flattening' and 'restoration of balanced section',and other methods, the sedimentary boundary, structure and the evolution history of the Tianhuan depression on the western margin of the Ordos Basin are reestablished. The following results have been obtained. (1) The west boundary of the Late Triassic Ordos Basin was far beyond the scope of the current basin. The basin is connected with the Late Triassic Hexi Corridor Basin, and its western margin did not have tectonic characteristics of a foreland basin. (2) The Tianhuan depression was first formed in the Late Jurassic. At the late stage it was impacted by the late Yanshanian and Himalayan tectonic movement and the depression axis gradually moved eastwards to the present location with a cumulative migration distance of ~30 km. (3) Eastward migration of the depression axis caused adjustment and even destruction of the originally formed oil and gas reservoirs, so that oil and gas remigrated and aggregated, resulting in secondary structural reservoirs formed at high positions on the western flank of the depression. | LI Xiangbo LIU Huaqing WANYAN Rong WEI Lihua LIAO Jianbo FENG Ming MA Yuhu BAI Yunlai | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 9 |
| 4 | Properties of Continental Margin and its Hydrocarbon Exploration Significance in Cambrian in the Southern Ordos Kratogen of North China显示文摘It is important to determine the properties of the tectonics in Cambrian period for the sake of prospecting deep hydrocarbon in the near future in the southern Ordos Kratogen of North China. Authors chose the marginal areas of the southern Ordos basin as the object of research, avoided the effects of both the Qinling Orogenic Belts (QOB) and Weihe River Graben (WRG) whose geological structures are too complicated. By surveying typical Cambrian outcrops and profiles in the basin edges and based on the cores of 57 wells which penetrated the Cambrian in the basin, combined with the seismic profiles, the field gammaray measuement results and the carbon isotope analysis, Authors conclude that the southern margin of the Ordos Kratogen during Cambrian was a passive continental margin which resulted from sea-floor spreading of the Ancient Qinling Ocean. Epicontinental sea carbonate sediments formed in the south Ordos continental margin during Cambrian, and were predominant as tidal flat and o litic shoal. Both transgression-regression process and the change in palaeostructure have the obvious cyclicity. Using the junction between the late Nangao age of Qiandong epoch and the early Duyun age of Qiandong epoch as a boundary, each had a full transgression cycle at the upper and lower stages. The early cycle is characterized by high energy clastic littoral facies while the late cycle is characterized by carbonate ramp on which clear water and muddy water developed alternately changing to carbonate platform last. During the early stages, An aulacogen was formed in the middle section of the southern margin. The southern Ordos margin was uplifted and denudated by the Huaiyuan Movement which occurred from the late Furongian age to the middle Flolan age and the history of the passive continental margin ended and entering into a new tectonic cycle. The unconformity surface caused by the Huaiyuan Movement, along with its neighborhood areas where dissolved pores and cavities are developed, may be another important district for good hydrocarbon reservoirs (excluding the unconformity surface on the top of the Ordovician in the Ordos basin). | BAI Yunlai MA Yuhu HUANG Yong LIAO Jianbo LIU Xiaoguang | 2013 | Acta Geologica Sinica(English Edition)2013，87，3： | 9 |
| 5 | Influence of Mg Contents on Aging Precipitation Behavior of Al-3.5Cu-xMg Alloy显示文摘The influence of Mg content on the microstructures and mechanical properties at room temperatures of Al-3.5Cu-(0.71-1.81)Mg alloys was studied.Precipitation phases in the alloys were identified by TEM and HRTEM.The results show that when Mg contents increase from 0.71 to 1.81 wt%,the precipitates are transformed from S,S″,Ω,and θ' phases to Sand S′phases,and Ω phase is first observed in Al-3.48Cu-0.71 Mg alloy with Cu/Mg mass ratio of 5 during the conventional aging heat treatment(190 ℃/12 h).Regard to aging hardness effect of the tested alloys,the hardness of the alloys improves with the increase of Mg content,but the increases become slow when Mg content is greater than 1.35 wt%. | Siyu Li Jin Zhang Jinlong Yang Yunlai Deng Xinming Zhang | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，1： | 6 |
| 6 | RNA Interference-based Suppression of Phosphoenolpyruvate Carboxylase Results in Susceptibility of Rapeseed to Osmotic Stress显示文摘The diverse functions of phosphoenolpyruvate carboxylase(PEPCase;EC 4.1.1.31) in C3 plants are not as well understood as in C4 plants.To investigate the functions of PEPCase in C3 plants,rapeseed(Brassica napus L.) PEPCase gene(referred to as BNPE15) was silenced by the RNA interference(RNAi) technique.Under normal growth conditions,no significant difference in lipid content and fatty acid composition were found between wild-type(WT) and transgenic rapeseed plants.However,when these plants were subjected to osmotic stress induced by osmoticum polyethylene glycol(PEG-6000),membrane permeability and membrane lipid peroxidization in roots and leaves of transgenic plants were higher than those of WT plants.It suggested that transgenic plants are more susceptible to osmotic stress than WT plants.Taken together,the results showed that the suppression of PEPCase by RNAi leads to susceptibility to osmotic stress in rapeseed,and PEPCase is involved in the response of C3 plants to environmental stress. | Mei Chen Yunlai Tang Jingmei Zhang Mingfeng Yang Yinong Xu | 2010 | Journal of Integrative Plant Biology2010，52，6： | 4 |

| 8 | Synthesis of Mesoporous Anatase TiO2 Sphere with High Surface Area and Enhanced Photocatalytic Activity显示文摘Mesoporous anatase TiO_2 spheres with high surface area(119 m^2g^(-1)) were successfully synthesized via a facile and green template-free method. The prepared TiO_2 was characterized by X-ray diffraction(XRD),N_2 adsorption, scanning electron microscopy(SEM), transmission electron microscopy(TEM) and UV–vis absorbance spectra. It was found that the prepared TiO_2 is characterized by pure anatase phase, which shows uniform spheres and has a typical mesostructure with a high specific surface area and a large pore volume. The effects of complexant(acetylacetone) amount, crystallization temperature and calcination temperature were also investigated. Based on the results, a sketch for the preparation of mesoporous TiO_2 was proposed. First, complex formed between tetrabutyl titanate and acetylacetone in ethanol. After introduction of aqueous of ammonia sulfate and urea, hydrolysis of tetrabutyl titanate would occur slowly,and sol of TiO_2 was formed. Then, crystallization proceeded under hydrothermal conditions. Calcination process favored the formation of bigger TiO_2 crystal through combining of the small crystals in TiO_2.This led to the formation of bigger mesopores between TiO_2 crystals. Photocatalytic activity of the prepared TiO_2 was evaluated by decomposition of methyl orange. | Tianliang Lu Youqiang Wang Yingli Wang Lipeng Zhou Xiaomei Yang Yunlai Su | 2017 | Journal of Materials Science & Technology2017，33，3： | 3 |
| 9 | Oral microbiome and risk of malignant esophageal lesions in a high-risk area of China:A nested case-control study显示文摘Objective:We aimed to prospectively evaluate the association of oral microbiome with malignant esophageal lesions and its predictive potential as a biomarker of risk.Methods:We conducted a case-control study nested within a population-based cohort with up to 8 visits of oral swab collection for each subject over an 11-year period in a high-risk area for esophageal cancer in China.The oral microbiome was evaluated with 16 S ribosomal RNA(rRNA)gene sequencing in 428 pre-diagnostic oral specimens from 84 cases with esophageal lesions of severe squamous dysplasia and above(SDA)and 168 matched healthy controls.DESeq analysis was performed to identify taxa of differential abundance.Differential oral species together with subject characteristics were evaluated for their potential in predicting SDA risk by constructing conditional logistic regression models.Results:A total of 125 taxa including 37 named species showed significantly different abundance between SDA cases and controls(all P<0.05&false discovery rate-adjusted Q<0.10).A multivariate logistic model including 11 SDA lesion-related species and family history of esophageal cancer provided an area under the receiver operating characteristic curve(AUC)of 0.89(95%CI,0.84-0.93).Cross-validation and sensitivity analysis,excluding cases diagnosed within 1 year of collection of the baseline specimen and their matched controls,or restriction to screenendoscopic-detected or clinically diagnosed case-control triads,or using only bacterial data measured at the baseline,yielded AUCs>0.84.Conclusions:The oral microbiome may play an etiological and predictive role in esophageal cancer,and it holds promise as a non-invasive early warning biomarker for risk stratification for esophageal cancer screening programs. | Fangfang Liu Mengfei Liu Ying Liu Chuanhai Guo Yunlai Zhou Fenglei Li Ruiping Xu Zhen Liu Qiuju Deng Xiang Li Chaoting Zhang Yaqi Pan Tao Ning Xiao Dong Zhe Hu Huanyu Bao Hong Cai Isabel Dos Santos Silva Zhonghu He Yang Ke | 2020 | Chinese Journal of Cancer Research2020，32，6： | 3 |
| 10 | Conversion of syngas to higher alcohols over Cu-Fe-Zr catalysts induced by ethanol显示文摘Ethanol induced method was applied to prepare Cu-Fe-Zr catalysts for conversion of syngas to higher alcohols.The catalytic performance of the catalysts induced by ethanol was superior to that of the catalyst prepared by the conventional precipitation method.Among various procedures for ethanol induced method,it was found that incorporation of ethanol in the precipitation process was the better.After incorporation of ethanol,the crystal size of CuO decreased and the reduction of copper species became easier.The better activity of Cu-Fe-Zr catalysts prepared by ethanol induced procedures was probably caused by the higher dispersion of Cu species. | Hongtao Zhang Xiaomei Yang Lipeng Zhou Yunlai Su Zhongmin Liu | 2009 | Journal of Natural Gas Chemistry2009，18，3： | 3 |
