Simple Method for Transforming Liquid Silicone Oils into High‐Quality Solid Silicone Resins

open access: yesHelvetica Chimica Acta, Accepted Article.
A novel, cost‐effective and sustainable method for the synthesis of highly crosslinked methyl silicone resins by upcycling silicone oil, specifically linear polyorganylsiloxanes was developed. Using mild reaction conditions, a high yield of DT resins (up to 90%) along with silicone oligomers as a by‐product was achieved.

A review of the development and implementation of the critical source area concept: A reflection of Andrew Sharpley's role in improving water quality

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.

Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

open access: yesJournal of Environmental Quality, EarlyView.
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...
