Mechanical–Structural Investigation of Ion-Exchanged Lithium Silicate Glass using Micro-Raman Spectroscopy
(American Chemical Society, 2016-03-21)
Micro-Raman spectroscopy was used to determine the structural modifications occurring in a simple ion-exchanged glass. The base lithium silicate composition 30Li2O–70SiO2 was studied as it underwent ion exchange, Li+ ↔ K+, ...
Nanoindentation Study of the Surface of Ion-Exchanged Lithium Silicate Glass
(American Chemical Society, 2016-02-25)
Variations in mechanical properties (stiffness and hardness) were measured as a function of case depth in ion-exchange glasses using nanoindentation. A simple silicate composition, 30Li2O–70Si2O, was exchanged (Li+ ↔ K+) ...
The first series of alkali dipyrrinato complexes
(2010-08)
The first series of alkali dipyrrinato complexes is reported, encompassing lithium, sodium, and
potassium salts of meso-unsubstituted and meso-aryl-substituted derivatives. By varying the
substituents at the meso position, ...

Decarboxylative Arylation of Substituted Pyrroles N-protected with 2-(Trimethylsilyl) ethoxymethyl (SEM)
(Canadian Journal of Chemistry, 2018)
Palladium-catalyzed decarboxylative arylation is reported using pyrroles N-protected with the 2-(trimethylsilyl) ethoxymethyl (SEM) group and featuring 2-, 3- and 4-substituents about the pyrrolic framework. In contrast ...
Synthesis and biological evaluation of prodigiosene conjugates of porphyrin, estrone and 4-hydroxytamoxifen
(Bioorganic & Medicinal Chemistry, 2013)
To generate the first series of prodigiosene conjugates, the tripyrrolic skeleton was appended to estrone, tamoxifen and porphyrin frameworks by way of ester linkers and various hydrocarbon chain lengths. The ability of ...
Microwave-assisted reduction of F-BODIPYs and dipyrrins to generate dipyrromethanes
(Canadian Journal of Chemistry, 2013)
The reduction of BODIPYs and dipyrrins to dipyrromethanes, via a reaction involving ethylene glycol and sodium methoxide, is reported. When benzyl alcohol is used in place of ethylene glycol, the addition of 2,4-dinitrop ...
An Improved Method for the Synthesis of F-BODIPYs from Dipyrrins and Bis(dipyrrin)s
(Organic Letters, 2012)
An improved methodology for the synthesis of F-BODIPYs from dipyrrins and bis(dipyrrin)s is reported. This strategy employs lithium salts of dipyrrins as intermediates that are then treated with only one equivalent of boron ...
