Hyperpolarized Long-T1 Silicon Nanoparticles for Magnetic Resonance Imaging [PDF]

, 2009
Silicon nanoparticles are experimentally investigated as a potential hyperpolarized, targetable MRI imaging agent. Nuclear T_1 times at room temperature for a variety of Si nanoparticles are found to be remarkably long (10^2 to 10^4 s) - roughly ...

Property Modification of Ball-milled Slurries using Wet-jet Milling

Journal of the Japan Society of Powder and Powder Metallurgy, 2008
Wet-jet milling process was employed to modify the properties of Al2O3 slurry after ball milling. Particle size distribution of slurry wet-jet milled after ball milling corresponded to that of ball-milled slurry. However, the viscosity of ball-milled slurry increased rapidly with time, whereas the viscosity of the slurry wet-jet milled after ball ...

A cleaner and efficient extraction of Mn from low-grade Mn carbonate ores by ball milling-enhanced Fe2(SO4)3 leaching: Acid consumption reduction

Cleaner Engineering and Technology, 2021
High acid consumption is a common problem in the treatment of low-grade Mn carbonate ores by H2SO4 leaching process. In this study, Fe2(SO4)3 solution was used to replace the commonly used H2SO4 solution as a leaching agent to leach Mn from low-grade Mn ...
