Thermal Transformation of Aqueous Lignin Suspension into Nanoparticle Dispersion and Its Associative Properties

Zhaoquing L., Gast J.C., Bottorff K.J., Solenis LLC, US

LIGNIN IS THE SECOND MOST ABUNDANT BIOPOLYMER. NANOPARTICLE DISPERSIONS OF LIGNIN WERE OBTAINED BY SIMPLY HEATING IN A CONTROLLED MANNER A PARTIALLY NEUTRALIZED LIGNIN SUSPENSION IN WATER. THE LIGNIN NANOPARTICLES WERE FOUND TO FORM STABLE [...]

New Insights into Microstructure, Rheology & Molecular Level Structural Changes During Self-Assembly & Gelation in Complex Fluids Through Combined DLS-Optical Microrheology-Raman Spectroscopy

Amin S., Blake S., Kidder L., Lewis E.N., Kenyon S., Malvern Instruments, US

Soft Matter/Complex fluid systems are ubiquitous across a range of industrial and consumer sectors. In many instances the final product format of these complex fluids are gels or soft solids and the processing and product [...]

Mechanical Properties of PLA-Jute Composites by Using Natural Rubber and Epoxidized Natural Rubber as Impact Modifiers : Effect of Molding Technique

Ruksakulpiwat Y., Tonimit P., Kluengsamrong J., Suranaree University of Technology, TH

Jute fiber was used as a reinforcing fiber in poly (lactic acid) (PLA) composites. Natural rubber (NR) and epoxidized natural rubber (ENR) are used as impact modifiers of jute-PLA composite. The composite specimens were prepared [...]

Effect of Silica Nanoparticles on Rheological Properties and Gelation Temperature of Biodegradable Polymer Gels

Florián-Algarín V., Acevedo A., University of Puerto Rico-Mayagüez, PR

The discovery of new potent and insoluble drugs has emphasized the need for personalized dosages and novel drug-delivery systems. The use of biodegradable polymers is a good alternative to form films in which a solid [...]

Glycosaminoglycan model glass substrates and cancer cell interactions

Peramo A., Wright G., Meads M.B., Dalton W.S., Matthews G., University of South Florida, US

The static adhesion of three cancer cell lines to surfaces functionalized with glycosaminoglycans was performed and the possible involvement of heparanase in this process was analyzed. Four different glycosaminoglycans (heparan sulfate, chondroitin sulfate A, chondroitin [...]

Morphological Consequence of Sonication on Lignin-CNT-Epoxy Composite

Thomas D., Edwards J., Parker R., Ku C.-L., Bryan D., Liao Y-H, Liang R., Florida A & M University, US

This project will utilize SEM and molecular modeling analysis to determine morphological consequences of presonication time on lignin particle size and the joint sonication of lignin with CNT. The investigation will yield a more fundamental [...]

Development of a Biologically Enhanced Carbon Nanotube Based Composite

Parker R., O’Neal R., Fisher D., Davey Kirk, Liang R., Edwards J., Florida A&M University, US

Composite materials continue to be important to the evolution of human space flight activity. The low weight/high strength ratio and thermal properties of carbon based composite materials in particular that make them well suited for [...]
