Processing-Property-Structure Relationships Of Carbonaceous Materials Derived From Renewable Lignin Products, Valerie García-Negrón
Processing-Property-Structure Relationships Of Carbonaceous Materials Derived From Renewable Lignin Products, Valerie García-Negrón
Masters Theses
Efforts to effectively use lignin, a by-product of paper and biofuels production, have been carried out for several decades. This renewable resource has potential for use as a carbonaceous material due to its aromatic structure and high carbon content, reminiscent of graphite. The search for new carbon-based materials is extremely active, because they are necessary components in many applications, such as energy storage, electronics, catalysis, and lubricants. Traditional carbon-based materials are derived or mined from petroleum or coal, thus, contributing to pollution, national security risks, and anthropogenic climate change. Lignin, a carbon-rich component found in the tissues of vascular plants, …

Research outputs 2014 to 2021
To enhance the wear resistance and corrosion resistance of Ni-based coatings, carbon fibers reinforced nickel-based composite coatings (CFs/Ni) were fabricated on the surface of 1Cr13 stainless steel by laser cladding (LC). The microstructure characteristics, microhardness, wear and corrosion performances of the composite coatings were investigated. The results show that CFs can effectively improve the corrosion and wear resistances of Ni-based coatings. With increasing laser scanning speed, the morphology of CFs in composite coatings is more integral and the corrosion and wear resistances of the composite coatings are improved. Especially, when laser scanning speed is increased to 8 mm/s, the average …
