Effects of treating lignocellulosics with alkaline hydrogen peroxide on feed intake and digestion by dairy cattle
… alkaline hydrogen peroxide (AHP) treatment of lignocellulosics has been shown to increase degradation of structural carbohydrates by ruminal microbes. Therefore, four experiments were conducted to investigate the effects of AHP-treated wheat straw (WS) or oat hulls (OH) on feed intake, nutrient …

Cure studies of network-forming polyurethanes
The polyhydroxy character of lignocellulosics and their natural abundance make them good candidates for the manufacture of polyurethanes. The cure characteristics of hydroxypropyl-cellulose and hydroxypropyl lignin (HPC and HPL, respectively) with polymeric methylene diphenyl diisocyanate (MDI) was …
