Abstract
Templates for helix-structured silica microtubules are generated by subject
ing worm-shaped micelles of cetyltrimethylammonium bromide to so-called Tay
lor vortex flow conditions between a rotating and a stationary cylinder at
controlled speed. Silica deposition from TEOS and template dissolution prod
uce helical tubules about 100 nm in diameter and a few micrometers long (se
e Figure), potentially useful for chiral catalysis or optical applications.
