Synthesis of functionalized polyhedral oligomeric silsesquioxane (POSS) macromers by microwave assisted 1,3-dipolar cycloaddition

Hydrogen adsorption and diffusion in amorphous, metal-decorated nanoporous silica

“…This is a level of theory used by other researchers [51] to calculate properties for similar structures. We first performed unconstrained geometry optimization on an isolated spherosilicate cube with a eOTiCl 3 group attached into it and an isolated H 2 molecule, Then the optimized H 2 was placed near the eOTiCl 3 group and the geometry of the combined structure was optimized.…”

Morphology control and inducing a curvature on the domain interface by increasing the steric bulk of polymethacrylate in POSS-containing diblock copolymers

“…In recent years, strongly segregating BCPs such as silicon‐containing BCPs have been highly promising for such applications . In particular, POSS‐containing BCPs have a T g highly suitable for forming thin films and a naturally increased etching contrast to oxygen plasma treatment, making it highly suitable for fabricating well‐defined nanopatterns . By tuning the BCP to self‐assemble into hexagonally packed cylindrical structures of the POSS‐containing domain with a parallel orientation relative to the substrate, periodic L/S structures can be obtained after selectively etching the organic major domain.…”

Nonthermal Effects of Microwaves in Organic Synthesis

“…This is especially true of 1,3-dipolar cycloadditions (cf., Chapter 17) [93]. Because these reactions are well known to react via asynchronous mechanisms, MW-specific effects are expected, and very often apparent when MW and were closely checked under similar sets of conditions [94,95]. A specific lit.…”
