Developing a fundamental understanding of polymer nanocomposite photodegradation and CNT release characteristics

Lankone R.S., Wang J., Ranville J.F., Fairbrother D.H., John's Hopkins University, US

As the development, production, and use of polymer nanocomposites continues to rise, so too does the likelihood for exposure of their embedded nanoparticles to humans and the environment following nanoparticle release. The release of carbon [...]

Linear and Nonlinear Optical Properties of Palladium Nanoparticle Reinforced Fluoropolymer Composites

Spicer J., See K., Katsumi Y., Zhang D., Brupbacher J., Vargo T., John's Hopkins University, US

The linear optical properties of a functionally graded, palladium nanoparticle reinforced fluorinated ethylene polymer matrix nanocomposite (PMNC) were investigated in this work. Synthesized through repeated infusions of a palladium organometallic precursor gas into an insulating, [...]

Quantum Dot-Mediated Separation-Free Assay for Point Mutation Detection

Yeh H.C., Ho Y.P., Wang T.H., John's Hopkins University, US

We describe a novel semiconductor quantum dot (QD)-based biosensing assay for single nucleotide polymorphism (SNP) detection. By integrating a QD-mediated dual-color fluorescence coincidence detection method with oligonucleotide ligation assay (OLA), we have achieved rapid SNP [...]

A Stochastic Projection Method for Microchannel Flow

Le Maitre O.P., Knio O.M., Ghanem R.G., Najm H.N., John's Hopkins University, US

The construction and implementaion of a stochastic flow solver is described. The solver combines a spectral stochastic uncertainty representation scheme with a finite difference projection method for flow simulation. The uncertainty quantification scheme is based [...]
