This paper considers fracture characteristics of OFHC copper, Armco iron and 4340 steel. The materials are subjected to torsion tests over a range of strain rates, Hopkinson bar tests over a range of temperatures, and quasi-static tensile tests with various notch geometries. A cumulative-damage fr...
Leaching characteristics of heavy metals from three historical Pb-Zn mine tailings heaps in the United Kingdomdoi:10.1016/0148-9062(94)92449-XELSEVIERInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts
Study on the form partitioning and content of heavy metals in soil particles with different sizes is crucial for preventing and controlling heavy metals pollution, but few studies regard soil contaminated by heavy metals as a homogeneous body. In this st
In recent years, transgenic hairy root tissue is widely used in the phytoremediation research of heavy metals and organic pollutants,and it has become a convenient model to investigate the toxic response mechanism of pollutants in the laboratory. To explore the response differences among Solanum nigrum...
What is a covalent bond and what are the important characteristics of covalent bonds? Describe the structure of the water molecule and indicate how this structure is responsible for any of the unique properties of this vital compound. Describe the st...
First, we create two-dimensional racetracks from freestanding films transferred onto sapphire substrates and show that they have nearly identical characteristics compared with the films before transfer. Second, we design three-dimensional racetracks by covering protrusions patterned on a sapphire wafer ...
To fully understand the behavior and fate of mercury (Hg)(Ⅱ) in forest soils, a series of batch experiments were conducted to determine the adsorption and desorption characteristics of Hg(Ⅱ) by three dark brown forest soils from Mount Taishan, Laoshan Mountain, and Fanggan Village in ...
