Development of Drug Delivery System Using Bio based Calcium carbonate Nanoparticles

Jeelani S., Pawar K., Ramapuram J., Rangari V., Render D., Samuel T., 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 [...]

Supermagnatic Iron Oxide Nanoparticles Toxicity to Mammalian Cells

Parveen A., Rangari V., Singh S.R., Tiwari P., Vig K., Alabama State University, US

The present study investigates the development of superparamagnetic iron oxide nanoparticles as a controlled release drug formulation and use as anticancer therapeutic agents. Iron oxide nanoparticles (IONPs) were synthesized using ultrasonic irradiation of iron pentacarbonyl [...]

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

Hossain M.K., Hosur M., Jeelani S., Okoro C., 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 [...]

Surface Modification and Performance Analysis of Jute Based Nanophased Green Composite

Dewan M.W., Hossain M.K., 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 [...]

CNT and Silver-CNT Nanoparticles provide immune responses against RSV

Adiani L., Boyoglu C., Boyoglu S., Dennis V., Mishra M., Rangari V., Singh S.R., Alabama State University, US

Nanobiotechnology and its potential to be used in treating and diagnosing general and viral infections have allowed us to step into a new realm, when dealing with Respiratory synctical virus (RSV). RSV has long been [...]

Fabrication and Thermomechanical Characterization of CNF-Filled Polyester and E-Glass/Polyester Nanophased Composites

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

A high intensity ultrasonic liquid processor was used to infuse CNFs into the polyester matrix which was then mixed with catalyst using a high speed mechanical agitator. Results showed the significant improvement of mechanical properties [...]

High Strain Rate Compression Behavior of Conventional and CNF-Filled-Nanophased Glass/Polyester Composites

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

A high intensity ultrasonic liquid processor was used to infuse carbon nanofibers (CNFs) into polyester matrix that was then mixed with hardener using a high speed mechanical agitator. The trapped air and reaction volatiles were [...]

Antimicrobial properties of silver coated CNT

Adiani L., Ashour D., Boyoglu S., Jeelani S., Mohammad G., Pillai S., Ram Singh S., Rangari V., Subbarayan P., Alabama State University, US

Surface microbial infestation of biomedical devices such as catheters, prosthetics, and implants can result in serious infection and device failure. Surface-centered infections are also implicated in food spoilage, and spread of food-borne diseases. Hence, there [...]

Silver Coated Carbon Nanotubes Inhibit RSV Infection

Adiani L., Boyoglu S., Pillai S., Rangari V., Singh S.R., Subbarayan P., Vig K., Alabama State University, US

Respiratory Syncytial Virus (RSV) is a member of the genus Pneumovirus in the family of Paramyxoviridae. It is one of the most common causes of upper and lower respiratory tract infections, bronchiolitis and pneumonia worldwide [...]

Respiratory Syncytial Virus Inhibition by Gold and Titanium Nanoparticles

Boyoglu S., Pillai S., Rangari V., Singh S.R., Vig K., Alabama State University, US

Respiratory Syncytial Virus (RSV) is the leading cause of severe respiratory illnesses including bronchiolitis and pneumonia in young children. The RSV surface proteins F (fusion) and G (attachment) are major targets for vaccine development against [...]
