Stripes are Stars! Pt Helps Fe to Stay Magnetized

A. Enders, R. Skomski (Nebraska MRSEC), J. Honolka, K. Kern, K. Fauth, G. Schuetz (MPI Stuttgart, Germany), P. Varga (TU Vienna, Austria) and H. Ebert (LMU Munchen, Germany)
The magnetic anisotropy energy is among the most important functional properties of magnetic elements. It determines the orientation and stability of the magnetization as well as the mechanisms and the dynamics of the magnetization reversal.

Battery material could lead to ultra-fast recharging of many devices

Gerbrand Ceder (MIT), ByoungWoo Kang (MIT)
  Professor Gerd Ceder, co-leader of the MIT battery IRG, and MRSEC-supported graduate student ByoungWoo Kang wanted to dispel the myth that batteries have low power rates.

Green Chemistry of Poly(l-lactides)

W. Swope1, R. Waymouth2, J. Hedrick1, and C. Wade1 1: IBM Almaden Research Center, 2: Stanford University
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

Ajay Dambal and Eric Shaqfeh, Dept. of Chemical Engineering, Stanford
The dynamics of entangled polymer solutions far from equilibrium is, at present, a subject of considerable interest because the "natural" modifications to tube or reptation-based theories have not been successful.Â’  In such systems, polymer molecules are highly entangled, which results in the motion o

Flow-Enhanced Vesicle Deformation in the Four-roll Mill

Susan Muller, Dept. Chemical Engineering, UC Berkeley
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

M. Chung and S. Boxer, Dept. of Chemistry, Stanford University
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 DNA strands are immobilized by click chemistry to a silica surface, whose remaining surface is passivated to prevent direct assembly of a solid supported bilayer.Â’  Then giant unilamellar vesicles (G

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. Working with PCCM faculty Wole Soboyejo and Craig Arnold and their graduate students, the PUMA high school students built their own solar ovens and solar cells from readily available materials, while a guest speaker shared her firsthand experience of the impact of solar cookers in economically and politically devastated regions of the world.

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 colloidosomes. These colloidosomes are highly stable in water, have size selective permeability, and are responsive towards external
