1Biomineralization of phototrophic microbes in silica-enriched hot springs in South China显示文摘Microbial mats in two hot springs in South China were sampled for the research of mineralization of microbes and its mechanism by the methods of geology and modern biology. The results show that hot spring microbes have the key capability for enrichment of Si, Al, Fe, Ca and other elements, and the microbes are also crucial for the formation of SiO2, CaCO3, clay and so on. The extracellular polymeric substances (EPS) play important roles in the process of mineralization of hot spring microbes, which mainly takes place in the layer of EPS outside cell wall or sheath of cyanobacteria. The sheath outside cell wall, which keeps the normal metabolism of cyanobacteria during the process of mineralization on its surface, is also considerable for the biomineralization of cyanobacteria. According to structure and mineralization characteristics of two microbial mats, the process of mineralization can be divided into three stages, namely, early surface mineralization, middle degradation mineralization, and late des- quamation of mineral. The above conclusions are significant for comprehension of the process of mineralization, the process of deposition and the preservation of microfossil in modern and ancient extreme environments.PENG XiaoTong ZHOU HuaiYang WU ZhiJun JIANG Lei TANG Song YAO HuiQiang 2007Chinese Science Bulletin2007,52,3:6
2Microbe-related precipitation of iron and silica in the Edmond deep-sea hydrothermal vent field on the Central Indian Ridge显示文摘Microbial mats, several millimeters thick and brown-yellow to white in color, were collected in hollow inside of chimney structure from Edmond hydrothermal field on the Central Indian Ridge. Microbes with shapes of rod and helical stalk-like filaments were observed in the microbial mats, and are com- monly characterized by their cells completely encrusted by thick mineralized layers, made up of large amounts of amorphous silica and minor amounts of iron oxides. Transmission Electron Microscope observation has demonstrated that the acicular Fe-bearing matter was not only heterogenously dis- tributed on the surface of the cell wall, but also deposited in the inside of cell, suggesting that bio-precipitation of Fe had occurred both on the surface and in the interior of cell. Microbial silicification was also commonly found in the mats. Silica usually precipitated homogeneously on the surface of the microbes and forms micro-laminated layers, which might be controlled by the inorganic process of precipitation in hydrothermal environment. The biomineralization phenomenon in the mi- crobial mats showed that the precipitation of Fe and Si was closely related to microbes in hydrothermal environment. Considering that hydrothermal activities provided required chemical elements for miner- alization, it is suggested that this biomineralization process also might be driven by hydrothermal ac- tivities at the sea floor to some extent.PENG XiaoTong ZHOU HuaiYang YAO HuiQiang LI diangTao TANG Song JIANG Lei WU ZiJun 2007Chinese Science Bulletin2007,52,23:5
3Early-stage mineralization of hydrothermal tubeworms: New insights into the role of microorganisms in the process of mineralization显示文摘As an important part of marine hydrothermal system, hydrothermal vent faunas live in hydrothermal inorganic environment and closely interact with hydrothermal inorganic environment. Sometimes, they can participate in the mineralization process of modern hydrothermal site. Hydrothermal vent faunas, particularly vestimentiferan and polychaete tubeworms, are occasionally preserved in the geological record. Study on the early mineralization process of hydrothermal vent fauna is significant for under- standing the interaction between mineral and organism, and also the formation and preservation mechanism of geological fossil in hydrothermal environment. In this paper, the early stage of miner- alization of Vestimentiferan Ridgeia piscesae tubes collected from Juan de Fuca Ridge is studied. The results showed that a lot of filamentous microorganisms were unevenly distributed on the surface of internal wall and in the interspace of the wall of tubeworm. In some cases, microorganisms aggregated as thin layers in or on the wall of tubeworm. The surfaces of microbial cells and the products of micro- bial degradation may play an important role in the early mineralization of tubeworm. Semitransparent thin layers of organic matter containing sulfur and sulfur granules were commonly found on the wall of tubeworm with lower degree of mineralization. The degradation production of these semitransparent thin layers may accelerate the mineralization of tube wall during the early stage. EDS results showed that on the tube walls some chemical elements such as Fe, P, Ca and Si are selectively enriched from ambient hydrothermal environment. Interestingly, P, Ca and Si covary with Fe content. Because element S originated from the bio-oxidation of H2S by symbiotic microorganism in the tissue of tubeworm, it can be considered as a biomarker when studying the mineralization process of tube wall. Based on the characteristics of tubeworms with different degrees of mineralization, we suggested that the early mineralization stage of tube wall was mainly controlled by microbial-induced mineralization and the degradation process of tube wall.PENG XiaoTong ZHOU HuaiYang TANG Song YAO HuiQiang JIANG Lei WU Zidun 2008Chinese Science Bulletin2008,53,2:3

9Sperm cryopreservation in the human sperm bank:11-year results of the Chinese mainland sperm banking network显示文摘To the Editor:Montegazza in 1866 was the first to suggest banks for frozen human semen.[1]In 1981,China's first human sperm bank was successfully established at the CITIC Xiangya Hospital.During the previous four decades,from 1981 to 2020,there were 27 human sperm banks in Chinese mainland.Human sperm banks provide cryopreservation of spermatozoa services for males needing to preserve fertility for an extended period in the Chinese mainland.Xiao Liu Qiling Wang Wenbing Zhu Zhou Zhang Wenhao Tang Huiqiang Sheng Jigao Yang Yushan Li Xiaowei Liang Tianqing Meng Zhiqiang Wang Faxi Lin Hao Dong Xiaojin He Xianglong Jiang Shanjun Dai Aiping Zhang Chunying Song Zuowen Liang Feng Zhang Xiaojun Wang Peiyu Liang Guihua Gong Xiaohong Huai Fuping Xinzong Zhang 2022Chinese Medical Journal2022,135,22:0
10Tsallis model-based separation of overlapped peak signals显示文摘A simple scheme for separating overlapped peak signals (OPS) is proposed, with the Tsallis distribution as the model for OPS processing and fractional-order differentiation as tool for the signal analysis, the relationships of the maxima and zero-crossing values of the Tsallis peak signal, separately, to the order of differentiation are established, leading to two types of parameter estimators, which are utilized, by adjusting the peak-shape parameter, to calculate the parameters of position, height and width of the Gaussian, Lorentzian and Tsallis distribution. The obtained characteristic parameters can be employed to fit the peak signals to be treated, thereby fulfilling the OPS decomposition.LI YuanLu ZHANG YingChao TANG HuiQiang 2010Science China(Information Sciences)2010,53,4:0

12The growth temperatures dependence of optical and electrical properties of InN films显示文摘InN films grown on sapphire at different substrate temperatures from 550℃ to 700℃ by metalorganic chemical vapor deposition were investigated. The low-temperature GaN nucleation layer with high-temperature annealing (1100℃) was used as a buffer for main InN layer growth. X-ray diffraction and Raman scattering measurements reveal that the quality of InN films can be improved by increasing the growth temperature to 600℃. Further high substrate temperatures may promote the thermal decomposition of InN films and result in poor crystallinity and surface morphology. The photoluminescence and Hall measurements were employed to characterize the optical and electrical properties of InN films,which also indicates strong growth temperature dependence. The InN films grown at temperature of 600℃ show not only a high mobility with low carrier concentration,but also a strong infrared emission band located around 0.7 eV. For a 600 nm thick InN film grown at 600℃,the Hall mobility achieves up to 938 cm2/Vs with electron concen-tration of 3.9×1018 cm-3.LIU Bin ZHANG Rong XIE ZiLi XIU XiangQian LI Liang KONG JieYing YU HuiQiang HAN Pin GU ShuLin SHI Yi ZHENG YouDou TANG ChenGuang CHEN YongHai WANG ZhanGuo 2008Science China(Physics,Mechanics & Astronomy)2008,51,3:0
13Heterogeneously-catalyzed aerobic oxidation of furfural to furancarboxylic acid with CuO-Promoted MnO_(2)显示文摘A cost-effective and sustainable noble-metal free catalyst system based on ubiquitously available Mn-Cu bimetallic oxides was served as efficient catalysts for furfural selective oxidation to furancarboxylic acid(FA). Interestingly, Mn_(2)Cu_(1)O_(x)exhibited an excellent furfural conversion of 99% with quantitative selectivity toward FA. Especially, we demonstrate the significant weakening of the Mn-O bonds with the incorporation of CuO into the Mn-Cu oxides, resulting in an improved OLreactivity of Mn_(2)Cu_(1)O_(x), which brings about a higher catalytic activity for furfural oxidation. More importantly, Mn_(2)Cu_(1)O_(x)could exhibit YFA>90% over 5 cycles of reusability test. Through this study, the relationship between the morphology, surface chemistry, and catalytic activity of Mn-Cu bimetallic oxides are elucidated, providing a simple and environmentally friendly catalytic strategy and scientific basis for the development of Mn-Cu bimetallic oxides bioderived molecular aerobic oxidation materials.Xin Yu Tingke Jin Huiqiang Wang Guoqing Zhang Wenlong Jia Lincai Peng Yong Sun Xing Tang Xianhai Zeng Shuliang Yang Zheng Li Feng Xu Lu Lin 2023Green Energy & Environment2023,8,6:0
