Removal of ruthenium using a silica gel supported reagent.

A solid-supported isocyanide ligand was developed to destroy active metathesis catalysts and to remove ruthenium byproducts from metathesis reactions. This method was able to significantly reduce the concentration of residual ruthenium from the organic products of several alkene and ene-yne metathesis reactions, under a variety of different conditions.

An in-depth study linking the infrared spectroscopy and photoluminescence of porous silicon during ambient hydrogen peroxide oxidation.

We carefully tailored a porous silicon (pSi) surface by oxidation with hydrogen peroxide (H2O2) to determine the time-dependent changes in nanocrystallite surface chemistries (e.g., Si-O-Si, SiH(x) [x = 1, 2], OySiH [y = 2, 3], and SiOH/H2O) and their influence on the pSi photoluminescence (PL).

Link between O2SiH infrared band amplitude and porous silicon photoluminescence during ambient O3 oxidation.

We carefully evaluate how porous silicon (pSi) surface oxidation by ozone (O(3)) and the resulting changes in nanocrystallite surface chemistries (e.g., SiOSi, SiH(x) (x = 1-3), O(y)SiH (y = 1-2), and SiOH) influence the pSi photoluminescence (PL).
