| 1 | The Lowest Boundary Age of Travertine in Dawanzhangjia Ravine, Huanglong, China显示文摘Objective One of major challenges in paleoenvironmental reconstruction using travertine in the Huanglong area is whether one can accurately determinate the age of travertine through high-precision and high-resolution dating techniques.Previous works of ^(14)C or ESR chronology,however,have shown that the variation of deposition ages of travertine was displayed | WANG Fudong DONG Faqin ZHAO Xueqin ZHANG Haiwei SUN Shiyong DAI Qunwei LI Qiongfang LI Gang MA Pengcheng | 2018 | Acta Geologica Sinica(English Edition)2018，92，2： | 3 |
| 2 | The Main Progress of Perovskite Solar Cells in 2020-2021显示文摘Perovskite solar cells(PSCs)emerging as a promising photovoltaic technology with high efficiency and low manufacturing cost have attracted the attention from all over the world.Both the efficiency and stability of PSCs have increased steadily in recent years,and the research on reducing lead leakage and developing eco-friendly lead-free perovskites pushes forward the commercialization of PSCs step by step.This review summarizes the main progress of PSCs in 2020 and 2021 from the aspects of efficiency,stability,perovskite-based tandem devices,and lead-free PSCs.Moreover,a brief discussion on the development of PSC modules and its challenges toward practical application is provided. | Tianhao Wu Zhenzhen Qin Yanbo Wang Yongzhen Wu Wei Chen Shufang Zhang Molang Cai Songyuan Dai Jing Zhang Jian Liu Zhongmin Zhou Xiao Liu Hiroshi Segawa Hairen Tan Qunwei Tang Junfeng Fang Yaowen Li Liming Ding Zhijun Ning Yabing Qi Yiqiang Zhang Liyuan Han | 2021 | Nano-Micro Letters2021，13，10： | 2 |

| 8 | Toward energy finance market transition:Does China's oil futures shake up global spots market?显示文摘China is breaking through the petrodollar system,establishing RMB-dominating crude oil futures market.The country is achieving a milestone in its transition to energy finance market internationalization.This study explores the price leadership of China's crude oil futures and identifies its price co-movement to uncover whether it truly shakes up the global oil spots market.First,we find that for oil spots under different gravities,China's oil futures is only a net price information receiver from light-,medium-,and heavy-gravity oil spots,but it has a relatively stronger price co-movement with these three spots.Second,for oil spots under different sulfur contents,China's oil futures still has weak price leadership in sweet,neutral,and sour oil spots,but it has strong co-movement with them.Third,for oil spots under different geographical origins,China's oil futures shows price leadership in East Asian and Australian oil spots at the medium-and longrun time scales and strong price co-movement with East Asian,Middle Eastern,Latin American and Australian oil spots.China's oil futures may not have good price leadership in global spots market,but it features favorable price co-movement. | Xingyu DAI Ling XIAO Matthew C.LI Qunwei WANG | 2022 | Frontiers of Engineering Management2022，9，3： | 0 |
| 9 | Composition Characteristic and Surface Charge Simulation of Atmospheric Dust Fall in Tianshui City显示文摘In order to know the particle size distribution and mineral compositions of dust in Maiji town, Tianshui City, Gansu Province, size distribution and physical compositions of atmosphere natural dropping dust have been analyzed. Based on the natural dropping dust ζ potential and the mass percentage of main mineral compositions in dust fall, we present two models (calculation method and hybrid method) for the zeta potential of atmospheric dust fall in pure water. The results illustrated that the natural dropping dust in Maiji town belongs to inhalable particles. The main mineral compositions and contents of the dust are quartz (57.08%), calcite (27.79%), albite (10.29%), muscovite (4.84%). Atmospheric dust fall in pure water is electronegativity and ζ potential decreased with increasing pH. There are some differences exist in the two modeling ways, but have a similar tendency. The zeta potential differences between natural dropping dust and modeling dust reflects the zeta potential contribution rate of main mineral particles in dust and the effect of trace polarity organic pollutants or other minerals. | CHEN Wu DONG Faqin DAI Qunwei YANG Jie NIU Zhen | 2013 | 矿物学报2013，33，S1： | 0 |
| 10 | Reciprocity Effect between Silicate Bacteria and Wollastonite显示文摘This paper studied the reciprocity effect between wollastonite and a strain silicate bacterium from purple soil. We analyzed the changes of pH value, glucose (GLU) residual concentration, electrolyte and Mn, Si, Fe etc. in the culture liquid with wollastonite after 48 h. The results show that the GLU wastage of silicate bacteria with wollastonite is 2.5 times of the bacterial contrast. It showed wollastonite could obviously accelerate silicate bacteria growth, but bacterial cell broken and distorted badly have been found by SEM analysis. The solubilization of silicate bacteria to Si element of wollastonite reached above 10 times. At the same time, three apices in FTIR of wollastonite (898 cm-1, 925 cm-1, 962 cm-1) descended obviously after the action of silicate bacteria, which shows that a great deal of Si has dissolved out. So we can get that wollastonite has remarkable effect to the growth of silicate bacteria and silicate bacteria has obvious solubilization to Si of wollastonite. | DAI Qunwei DONG Fa-qin ZHAO Yulian DENG Jianjun | 2013 | 矿物学报2013，33，S1： | 0 |
| 11 | Dissolution Characteristic Study on Dustfall in Citric显示文摘In this paper, the dissolution characteristics of Xining dustfall in citric acid solution was studied to evaluate the physical chemical change in acid conditions. pH along with conductivity was tested with time. FTIR, SEM and ICP analysis were applied to analyze the residuum and filtrate after 2 days’ dissolution experiment. It was shown in the pH/conductivity variation, solution’s pH rise sharply in the front 4 hours, then decrease slowly. After 4 hours, both the pH and conductivity become stable. Based on combined analysis of XRD and FTIR spectrum of dustfall before and after dissolution, that calcite and dolomite in dustfall are dissolved completely in the 0.05M citric acid solution in two days. Besides, amount of metal cations were extracted from the dustfall during the dissolution, including Ca2+,K+,Mg2+,Fe3+,Al3+,Si. In general, after the dissolution of dustall in citric acid, some minerals are dissolved and amount of metal elements are extracted. Carbonate minerals almost dissolved completely, also the structure of silicate minerals changed as the extraction of elements. | TANG Jun DONG Faqin DAI Qunwei DENG Yuequan ZHOU Shiping CHEN Wu | 2013 | 矿物学报2013，33，S1： | 0 |
