and chalcopyrite oxidative behaviors for prospective environmental and bioleaching applications[J]. The Journal of Physical Chemistry C, 2015, 119(32): 18364-18379. [40] RAND D A J. Oxygen reduction on sulphide......
Trans. Nonferrous Met. Soc. China 30(2020) 3210-3225 Microstructure and mechanical properties of ADC12 composites reinforced with graphene nanoplates prepared by ultrasonic assisted casting Jun-jie... by high-intensity ultrasonic assisted casting were investigated. The results indicated that high-intensity ultrasound can promote the uniform distribution of GNPs in the melt, resulting in refining the α(Al......
of the rubber damping ring, the vibration response of the system is suppressed. By changing the loss factor of the rubber damping ring, the vibration reduction rate of the system is significantly varied......
, a large number of concrete structures have produced varying degrees of damage for various reasons [1-10]. The damage of a concrete structure leads to the reduction in the bearing capacity. To ensure......
with the required standards specifying initial material for sodium reduction in tantalum powder for condensers. Similar results were obtained for the fluoride-sulfuric acid technology of PMC leaching... and fluoride- nitric acid schemes were developed for PMC processing. High-purity tantalum compounds can be obtained due to the schemes; lead can be transferred to solvable salt of lead nitrate. 2......
