2Structural, microstructural, and thermal characterizations of a chalcopyrite concentrate from the Singhbhum shear zone, India显示文摘The structural and morphological characterizations of a chalcopyrite concentrate, collected from the Indian Copper Complex, Ghatshila, India, were carried out by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The concentrate powder was composed mainly of free chalcopyrite and low quartz in about 3:1 weight ratio. The particle size was about 100 μm. Spectroscopic studies(FTIR, Raman, UV-visible) of the concentrate supported the XRD findings, and also revealed a marginal oxidation of the sulfide phase. The energy band gap of the sulfide was found to be 3.4 eV. Differential thermal analysis and thermogravimetry of the concentrate showed a decomposition of chalcopyrite at 658 K with an activation energy of 208 kJ ·mol-1, and two successive structural changes of silica at 848 K and 1145 K.Ritayan Chatterjee Shamik Chaudhuri Saikat Kumar Kuila Dinabandhu Ghosh 2015International Journal of Minerals,Metallurgy and Materials2015,22,3:2

4现代酸性矿山废水环境中的真核微生物:生物多样性、生理学、生物地球化学特征及其对古环境和早期生命演化的指示显示文摘现代酸性矿山废水(AMD)环境被认为是地球早期环境的理想对应物。AMD的水环境具有金属含量高、pH低的特点,这与太古代-早元古代时期海洋的某些环境条件十分类似。然而,尽管AMD的环境条件恶劣,但仍然栖息着非常丰富的原核和真核微生物,在这其中那些嗜酸的、营光合作用的真核微生物类群(特别是Eugnamutabilis)更是引起众多科学家极大的研究兴趣。本文全面概述了在AMD环境中发现的真核微生物Euglenids种群的生物化学、生理学和生物地球化学特征,以及这些特征对于理解生命演化和早期地球环境条件等方面的指示性作用。Euglenids的细胞具备区域化功能,因而具备需氧和厌氧的蜡酯和甾醇的双生物合成途径,同时它们还可以形成生物膜,所有这些均使得Euglenids能够在早期地球极端恶劣的环境条件下生存并持续演化。在AMD酸性环境中发育的富铁叠层石、嗜酸微生物的脂类化合物及其碳同位素比值以及它们独特的生理和生化特征可用于阐述真核生物的演化、地球早期大气中氧气的产生、条带状富铁建造的形成以及地球早期的环境演化等。Shamik Dasgupta 方家松 李江涛 张利 王嘉妮 韦兵兵 2013第四纪研究2013,33,1:1
