Journal ArticleDOI
Characterization of Biochars Produced from Cornstovers for Soil Amendment
James Weifu Lee,Michelle K. Kidder,Barbara R. Evans,Sokwon Paik,A. C. Buchanan,Charles T. Garten,Robert C. Brown +6 more
TL;DR: Since the CEC of the fast-pyrolytic cornstover char can be about double that of a standard soil sample, this type of biochar products would be suitable for improvement of soil properties such as CEC, and at the same time, can serve as a carbon sequestration agent.
Journal ArticleDOI
Biomimetic synthesis of calcium-deficient hydroxyapatite in a natural hydrogel.
Stacy A. Hutchens,Roberto Benson,Barbara R. Evans,Hugh O'Neill,Claudia J. Rawn,Claudia J. Rawn +5 more
TL;DR: The synthesis of the composite mimics the natural biomineralization of bone indicating that bacterial cellulose can be used as a template for biomimetic apatite formation and may have potential use as an orthopedic biomaterial.
Journal ArticleDOI
High-Yield Hydrogen Production from Starch and Water by a Synthetic Enzymatic Pathway
Y.-H. Percival Zhang,Barbara R. Evans,Jonathan R. Mielenz,Robert C. Hopkins,Michael W. W. Adams +4 more
TL;DR: Enzymatic hydrogen production from starch and water mediated by 13 enzymes occurred at 30°C as expected, and the hydrogen yields were much higher than the theoretical limit of anaerobic fermentations.
Journal ArticleDOI
Palladium-bacterial cellulose membranes for fuel cells.
TL;DR: Results of the study with palladium-cellulose showed that it was capable of catalyzing the generation of hydrogen when incubated with sodium dithionite and generated an electrical current from hydrogen in an MEA containing native cellulose as the polyelectrolyte membrane (PEM).
Journal ArticleDOI

Leif Hanson,Shane Harton,William T. Heller,Volker S. Urban,Barbara R. Evans,Sandrasegaram Gnanakaran,Arthur J. Ragauskas,Jeremy C. Smith,Jeremy C. Smith,Brian H. Davison +21 more
TL;DR: In this paper, the morphological changes in biomass during steam explosion pretreatment were investigated, showing that cellulose dehydration and lignin-hemicellulose phase separation are the main driving forces for biomass degradation.
