Program Highlights for year 2009

Green Chemistry of Poly(l-lactides)

As part of a series of studies on the green chemistry of poly(l-lactides), we have performed a theoretical study of the mechanism of ring-opening polymerization.

Polymer Dynamics in Concentrated Solution

The dynamics of entangled polymer solutions far from equilibrium is, at present, a subject of considerab

Flow-Enhanced Vesicle Deformation in the Four-roll Mill

This project leverages ongoing research on the dynamics of DNA and vescicles within CPIMA.Â’  We have developed a novel microfluidic four-roll mill that allows all flow types (from extension to shear to rotation) to be accessed and have previously used it to examine DNA tumbling in mixed flows and, most recently, to study vesicle dynamics.

DNA-tethered Membrane Formation From Giant Unilamellar Vesicles

We have developed two strategies forÂ’  preparing tethered lipid bilayer membrane patches on solid surfaces by DNA hybridization.Â’  In the first strategy, single-stranded

High School Student Research Internships at the Johns Hopkins MRSEC

The JHU MRSEC conducts extensive K-12 educational outreach programs aimed at pr

PUMA Students' Minds Energized by Energy

Students from Trenton, NJ participated in PCCM's Princeton University Materials Academy (PUMA), learning about materials science and engineering related to energy sustainability.

Colloidosome Assemblies.

Rotello developed a very rapid and convenient method for fabricating microspheres with walls made of nanoparticles, known as colloidosomes. In this method alkyne and azide functionalized iron oxide nanoparticles are co-assembled at the water-in oil-interface and covalently linked using “click” chemistry under ambient conditions to create magnetic
