Development of Drug Delivery System Using Bio based Calcium carbonate Nanoparticles

Render D., Rangari V., Samuel T., Ramapuram J., Pawar K., Jeelani S., Tuskegee University, US

The CaCO3 nanoparticles were derived from egg shells using sonochemical and mechanochemical methods. The glycerol and acetic acid were used as solvents in this process to avoid other toxic solvents. These nanoparticles were loaded with [...]

Mechanical Characteriztion of XD-Grade Carbon Nanotube/Epon 862 Processed by Dual Phase Dispersion Technique

Hossain M.K., Okoro C., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

In this research, a dual-phase dispersion method is studied combining a high intensity ultrasonic liquid processor with a three roll milling technique. Xd-grade carbon nanotubes (xd-CNTs) were infused into Epon 862 epoxy and then mixed [...]

Durability Study of Nanophased Jute-Based Green Composites

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Tuskegee University, US

Jute fiber reinforced biopol biocomposites with and without nanoclay were manufactured using treated and untreated jute fibers by a compression molding process and their durability study was performed using standard moisture absorption and flexure tests [...]

Mechanochemical and Sonochemical Synthesis of Bio Based Nanoparticles

Hassan T.A., Rangari V.K., Fallon V., Farooq Y., Jeelani S., Tuskegee University, US

•The size reduction process for seashell particles can be efficiently used for the production of Aragonite CaCO3 bio nanoparticles. A mechanichemical and sonochemical method was developed to synthesize bio calcium carbonate nanoparticles.

Characterization of Nanostructured Phenolic and Epoxy Composites Under Pulse Laser Degradation

Young S., Kumar A., Ludwick A., Aglan H., Tuskegee University, US

Phenolic and epoxy nanocomposites were fabricated and exposed to pulsed laser. The nanoreinforcements were alumina nanofibers (ANF) and multi-walled carbon nanotubes (MWCNT). The loading of the nanoreinforcement was kept the same for both the epoxy [...]

Mechanical and Moisture Resistance Performance of Silver Nanoparticle Reinforced Fish Skin Gelatin Films

Harding H., Ludwick A., Samuel T., Young S., Aglan H., Tuskegee University, US

Films from the biodegradable polymer gelatin have been studied for biomedical applications not only because of the film forming properties of gelatin, but also because of the availability and economical advantages of gelatin. In this [...]

Alignment of Si3N4 nanorods in Polypropylene single fibers

Rangari V.K., Yousuf M., Jeelani S., Tuskegee University, US

We have successfully aligned the silicon nitride nanorods in polypropylene single filaments through melt extrusion process. Significant enhancement in tensile properties has been observed for 1wt% rod shaped Si3N4 particles. The tensile results clearly show [...]

Surface Modification and Performance Analysis of Jute Based Nanophased Green Composite

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

The surface modification of jute fibers was accomplished by performing subsequent chemical treatments such as detergent washing, dewaxing, alkali and acetic acid treatment. The morphology of the modified surface was examined using the scanning electron [...]
