2White Light Emission Characteristics of Tb3+/Sm3+Co-Doped Glass Ceramics Containing YPO4 Nanocrystals显示文摘The Tb^(3+)/Sm^(3+) single-doped and co-doped glasses and glass ceramics containing YPO_4 nanocrystals have been synthesized by melt quenching method. The structural and luminescent properties of these glass specimens were investigated. Under 375 nm wavelength excitation, the emission spectra combined with blue, green and red bands were observed, which achieved the white light emission. Moreover, the energy transfer between Tb^(3+) and Sm^(3+)ions was validated by decay lifetime measurement and energy level diagram.The color coordinates(x = 0.333, y = 0.333), correlated color temperature(5595 K) and the color rendering index(Ra = 80.5) indicated that the glass ceramics were considered to be good lighting source. Hence,the YPO_(4-) based Tb^(3+)/Sm^(3+) co-doped glass ceramics can act as potential matrix materials for white lightemitting diodes under ultraviolet excitation.Zhixiong Zhang Yuepin Zhang Cheng Wang Zhigang Feng Weihuan Zhang Haiping Xia 2017Journal of Materials Science & Technology2017,33,5:2

4Linking microbial carbon pump capacity and efficacy to soil organic carbon storage and stability under heavy metal pollution显示文摘Heavy metal pollution can lead to a great loss of soil organic carbon(SOC).However,the microbial mechanisms that link heavy metal pollution to SOC remain poorly understood.Here,we investigated five apple-orchard soils at different distances from a Pb-Zn smelter.After assessing the heavy metal pollution level based on Grade Ⅱ of the national soil environmental quality standard(China),we found SOC stocks and microbial carbon pump(MCP)capacity(i.e.,microbial residue carbon)under medium and heavy pollution levels were significantly lower than those under safe,cordon and light pollution levels.The structural equation model showed causality in the SOC variations linked to pollution level through MCP capacity,which could contribute 77.8% of the variance in SOC storage.This verified MCP capacity can serve as a key parameter for evaluation of SOC storage under heavy metal pollution.Soil MCP efficacy,i.e.,the proportion of microbial residue carbon to SOC,also decreased under medium and heavy pollution.This suggested that,with a heavier pollution level,there was a higher rate of reduction of microbial residue carbon in soil than the rate of reduction of SOC.As MCP efficacy can be a useful assessment of SOC stability,the significantly positive relationship between MCP efficacy and clay content in correlation analysis implied that lower MCP efficacy was correlated with SOC stability under the heavier pollution level.Our study provides valuable insights to identify the mechanisms of microbially mediated C transformation processes that are influenced by heavy metal pollution in agroecosystems.Xiao Liu Xia Xu Tian Ma Shiwei Zhou Xiaoli Bi Hongbo He Xudong Zhang Weihuan Li 2023Soil Ecology Letters2023,5,2:1

9A classification of hydrological climatic seasons in the China seas显示文摘By using a method of boundary temperature index of seasons, a classification of hydrological climatic seasons in the China seas is made on the basis statistics of the sea surface air and water temperatures over the years. The results indicate that the assignment of hydrological seasons in the China seas differs with various sea areas. It may be divided into three climatic belts. In the temperate zone area, four seasons are clearly distinct with very long winter. While in the subtropical zone area, there is no winter throughout the year. The autumn is linked together with the spring, and the summer is unusually long. As for the tropical zone area, it is summer all the year round without any other seasons. In addition , the regular pattern of transformation of the four seasons and the regional characteristics of the length of each season are analyzed in greater detail. The results are in agreement with the continental seasonal classification and it is also shown that the results are reasonable andChen Shangji,He Weihuan Yao Shiyu and Zhang Shudong National Marine Data and Information Service, State Oceanic Administration, Tianjin 300171, China 1993Acta Oceanologica Sinica1993,12,1:0
