The diffusion of divalent nickel (Ni²⁺) from wet silica gels was investigated.
Silica gel is gaining interest as an encapsulation matrix for biological components.
The transport of biologically relevant species within the gel is determined by the
structural characteristics of the gel, which are in turn governed by synthesis
parameters....
The self-interstitial defect is commonly regarded as important in regulating diffusion
in silicon. A review of the literature reveals that the scientific bases for invoking the
self-interstitial defect are weak, while an alternate defect, the vacancy cluster, has been
largely ignored. One argument which has been used to establish dominance...
Due to the wide applications of inkjet printers in industry and our daily life, characterization of liquid droplets from inkjet printers, particularly the behaviors of the impact and diffusion of the droplets on the surface of and inside porous medium is of great interest. One conventional characterization method uses high-speed...
Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...
