Incorporation Of Lignin In Natural And Synthetic Biomaterials To Alter Mechanical And Biochemical Properties For Enhanced Wound Healing, Jorge Alfonso Belgodere
Incorporation Of Lignin In Natural And Synthetic Biomaterials To Alter Mechanical And Biochemical Properties For Enhanced Wound Healing, Jorge Alfonso Belgodere
LSU Doctoral Dissertations
It is estimated that chronic, non-healing wounds affect more than 6.5 million Americans annually, with an estimated healthcare cost beyond $14 billion. Here, we attempted to create composites of natural (collagen type I or gelatin-methacrylate) or synthetic (poly(ethylene glycol) polymers incorporating a natural plant component, lignin, to combat the costs and limitations current wound healing methods face. Three-dimensional matrices of collagen type I (Col I) are widely used in tissue engineering applications for its abundance in many tissues, bioactivity with many cell types, and excellent biocompatibility. Inspired by the structural role of lignin in plant tissue, we found that sodium …
Process Development Of Shale Gas Assisted Lignin And Biomass Reforming Through Novel Reaction Pathway And Catalyst Design To Produce Hydrogen Rich Syngas For Fuels And Value Added Chemicals, Amoolya D. Lalsare
Graduate Theses, Dissertations, and Problem Reports
Novel biomass reforming strategy through synergistic co-processing with flare gas (methane and carbon dioxide) was developed at West Virginia University. Hardwood biomass comprised of lignin, hemicellulose, and cellulose is abundant in the US and potentially a sustainable source of hydrogen through extensive reforming and gasification. Ever-increasing shale gas production in the US occasionally leads to flaring owing to stranded production across the US. Achieving biomass co-processing with natural gas about to be flared in such stranded shale plays is the underlying motivation here. A novel reaction pathway was discovered wherein methane and carbon dioxide assisted reforming of biomass could be …
Molecular Weight And Heating Value Of Lignin Extracted Using Deep Eutectic Solvent., Ekugbere Owen Owhe
Molecular Weight And Heating Value Of Lignin Extracted Using Deep Eutectic Solvent., Ekugbere Owen Owhe
Master's Theses
The molecular weight of lignin helps us to determine how lignin can be applied accurately in industry. The molecular weight can predict the behavior of lignin, and how it will function when combined with other materials. This thesis discusses how the molecular weight of lignin can be found with gel permeation chromatography (GPC) after acetylation with acetic anhydride and pyridine. Different lignins gave different number average molecular weight and weight average molecular weight values, which were likely due to the biomass source, type of extraction and solubility in the solvent of choice. How the structure of lignin changed after derivatization …
