2018年4月6日,中国地质大学生物地质与环境地质国家重点实验室联合德国波兹坦大学、澳大利亚阿德莱德大学、云南省考古所、美国宾西法利亚州立大学、南京师范大学、云南大学、美国哈佛大学、云南保山博物馆、丹麦哥本哈根大学等多家单位,在《Genes》上在线发表题为“Ancient DNA from giant panda (Ailuropoda melanoleuca) of south-western ...
Losing the ability to fly gave ancient penguins their unique locomotion style. But leaving the sky behind didn’t cause major changes in their brain structure, researchers from The University of T...
Geosynthetic clay liners (GCLs) are generally used in engineering projects due to their low hydraulic conductivity with water. The bentonite component contributes hydration-induced swelling and impart...
Geosynthetic clay liners (GCLs) are now a common feature of environmental lining systems in landfills, leach-heap pads, impoundments, irrigation canals and aesthetic ponds. The ASTM standard method (A...
Abstract: A synthetic octahedral-site-vacancy-free annite sample and its progressive oxidation, induced by heating in air, were studied by powder X-ray diffraction (pXRD), Mössbauer spectroscopy,...
Gold is used widely for capsules in high-temperature rock-melting studies because it is generally thought to absorb negligible Fe from silicate samples. However, we observed significant losses of Fe ...
The capsule materials Au, Ag Pd , and Pt, were tested for permeability to C-H-O fluids in a piston-cylinder apparatus at 10 kbar and 900(R)C1100?C. The capsules were embedded in boron ni- tride. Aft...
Abstract: Diffusion of alkali and low-atomic-number elements during the microbeam analysis of some silicates by analytical electron microscopy (AEM) has been known for some time. Our repeated analyses...
Accelerated soil erosion from construction sites and the resulting increase in downstream sediment load constitute a significant environmental problem. Laboratory studies indicate that small percentag...
