We consider model porous solids formed from initial packings of spheres with unimodal, Gaussian, or bimodal distributions of size; changes in pellet porosity are achieved by increasing microsphere radii and by randomly removing spheres from highly densified packings in order to simulate densification and coarsening, respectively.
Media was removed and spheres resuspended in one mL Accutase per 10 million cells, mixed gently and incubated at 37°C for 10 min. Accutase was replaced with an equal volume of 0.2% trypsin inhibitor (Sigma) and the cells were washed three times in 10 mL media.
The face-centered cubic (FCC) array spheres are usually used as the templates for the preparation of inverse opals: filling the high-refractive-index materials into the voids among the spheres, and then removing the spheres by calcinating or washing with organic solvents[10, 11].
In both cases, an issue may be the viability of embedding such defects inside 3-D PC's and may be solved by only partially removing the sphere or drilling it.
* "What seemed to be an increasingly open public sphere, removed from the world of commodity exchange, seems to be morphing into a private sphere of increasingly closed, proprietary, even monopolistic markets.
The tPS spheres were calcined at 300 °C for 2 h in air to remove sPS spheres.
No less removed from the sphere of classical crossover is tropicalia, a Brazilian countercultural movement.
And furthermore, when removed to a sphere worthy of his manifold perfections, we thought what an unpleasant angel he'd make".
When the public is removed, the private sphere takes over, charging more, and often creating unaccountable monopolies that bilk the public.
(a, b) Polystyrene honeycomb mask after removing silica spheres by immersion in 10 wt.% HF for 10 min and (c, d) photoresist honeycomb mask formed by sphere lithography.
