Molecular Layer Deposition (MLD) of a Blocked Mercapto Silane on Precipitated Silica

Improved deposition and deprotection of silane tethered 3,4 hydroxypyridinone (HOPO) ligands on functionalized nanoporous silica.

An improved synthesis of a 3,4 hydroxypyridinone (HOPO) functionalized mesoporous silica is described. Higher 3,4-HOPO monolayer ligand loadings have been achieved, resulting in better performance. Performance improvements were demonstrated with the capture of U(VI) from human blood, plasma and filtered river water.

Surface molecular imprinting in layer-by-layer films on silica particles.

An improvement to molecular imprinting in polymers, where bulk systems often suffer from slow dynamics of release and uptake, is the formation of thin films with imprinting sites that are more rapid to access by guest molecules. Based on our previous development of surface molecular imprinting layer-by-layer (LbL) films (SMILbL), the present paper presents selective imprinted sites in a surface...

Aging effects of precipitated silica in poly(dimethylsiloxane)

e report the transformation from gels to viscous fluids within a time period of 101–103 h in ixtures of precipitated silica in silicone oil. Scaling behavior in elastic and viscous moduli versus requency, similar to that reported by Trappe and Weitz Phys. Rev. Lett. 85, 449–452 2000 , has een observed for suspensions of different ages, silica volume fractions, and silicone oil molecular eights;...
