Hydrothermally stable heterogeneous catalysts for biorenewable-derived molecule conversions to chemicals
… important to this idea is the development of catalysts capable of handling the conditions inherent to biorenewable feedstocks. Water presents a significant challenge to today's catalysis. Using biorenewables, especially sugars, forces the processing to be in the condensed phase as they have …

The synthesis of fungicidal aminophosphonic acid derivatives
… against D. teres and D. avenae. The proton, carbon-13 and phosphorus-31 nmr spectroscopy of the compounds prepared was examined in detail with carbon-13 proving particularly useful. The carbon-phosphorus coupling constants varied along the alkyl chain in the phosphonopeptides with JPC=145-148 …
