Nanosilicate Filled Poly (vinyl chloride-co-vinyl acetate) and Epoxy Coatings for Steel Corrosion Protection

Allie L., Thorn J., Aglan H., Tuskegee University, US

The corrosion protection of nanosilicate filled poly (vinyl chloride - co - vinyl acetate) (VYHH) and epoxy resins has been studied. Nanosilicate was incorporated into VYHH at 0%, 0.5% and 1.5%wt loadings, and into epoxy [...]

Electrochemical Impedance and Thermal Characterization of Nano-Reinforced Vinyl Chloride/Vinyl Acetate Coating

Calhoun M., Ludwick A., Aglan H., Tuskegee University, US

A poly(vinyl chloride/vinyl acetate) copolymer (VYHH) with and without multi walled carbon nanotubes (MWCNTs) as reinforcements was used as a coating for steel substrates in order to evaluate its barrier properties against corrosion. Electrical impedance [...]

Synthesis of magnetic nanoparticles and its applications in drug delivery systems

Wright Bolden N., Rangari V., Jeelani S., Tuskegee University, US

Summary An improved method of drug delivery is much needed in areas such as cancer therapy in which more drugs needs to be delivered to a specific site and non-specific toxicities should be minimal. Drug [...]

Thermal and Mechanical Response of POSS coated Nanophased expandable foam core materials

Jones W.D., Rangari V.K., Jeelani S., Tuskegee University, US

A sonochemical technique has been established to coat variations of POSS nanoparticles on expandable microspheres. Thermal analyses results indicate that there is an increase in thermal stability of nanophased foam as compared to the neat [...]

In-situ synthesis of Cu nanoparticles on MWCNTS using Microwave irradiation

Rangari V.K., Dey S., Jeelani S., Tuskegee University, US

Microwave irradiation technique is successfully used to synthesize the copper coated MWCNTS in a one-pot reaction with and without surfactant. Since the graphite carbon absorbs the (in 2min 1100oC) maximum microwave radiation had led to [...]

Sonochemical Coating of TiC nanoparticles on expandable polymeric microspheres, Thermal & Mechanical properties of microspheres/epoxy nanocomposites

Rangari V.K., Hassan T.A., Mayo T. Watson Q., Jeelani S., Tuskegee University, US

Summary • Sonochemical method has been developed to coat nanoparticles on expandable polymeric microspheres. • n-Hexane is used as a solvent and proved to be a suitable solvent for sonochemical coating of nanoparticles on these [...]

An Investigation of Cellular Toxicity of Carbon Nanomaterials in African American Breast Cancer Cells

Taylor T., Dean D., Troy R., Leggett-Robinson P.M., Tuskegee University, US

Functionalized CNTs and CNFs are attractive not only because they are theoretically easier to disperse in organic solvents and water, but also because there is some evidence that these modifications may enhance solubility and/or decrease [...]

Nanostructured Polymeric Composites for High Performance Applications

Calhoun M., Allie A., Allie L., Allie A., Allie L., Aglan H., Dennig P., Tuskegee University, US

Nanostructured polymeric systems can mitigate some of the severe limitations of conventional polymeric composites. In the present research, nanocomposites of epoxy resins have been synthesized and evaluated. Organically modified layered silicate (OLS) particles and multiwalled [...]

Effect of particle size on the mechanical properties of polymer matrix nanocomposite

Zhou Y.X., White E.T, Jeelani S., Tuskegee University, US

In the present investigation, we have studied effect of inclusions size on mechanical properties of nanocomposite materials containing SC-15 epoxy resin and TiO2 particles. Micro sized particles have little effect on modulus and strength of [...]
