Silanized Primary bone marrow-derived dendritic cells (mouse) Toll-like receptor ligand conjugated to Meraz porous silicon particles to promote their et al. (2012) cellular uptake. Higher concentrations of particles led to lower cell viability due to increased number of particles taken up per cell ...

Covers for the melt can be used. Prebumed charcoal has been successfully used as a cover and is appHed hot directly from the prebumer. Fluxing and deoxidation is not necessary because of the strong affinity silicon has for oxygen. Silicon-heating scrap must be kept segregated from other scrap, because silicon as an impurity ia other alloys can promote a very coarse dendritic stmcture and weak porous castings.
