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

Macroscopic Addressable Arrays of Block Copolymers With Areal Densities of 10 Terabit/inch2 and Beyond
A collaboration between researchers funded by the DOE and NSF-supported
MRSEC and CHM at UC Berkeley and UMASS Amherst has led to a
breakthrough in the areal density of templates derived from block
copolymers (BCPs) having orientational registry over macroscopic
distances. The facets on a reconstructed single crystal surface, like
sapphire, were used to guide and direct the self-assembly of BCPs
having 3 nm cylindrical domains over arbitrarily large surfaces.

Fundamental MIT MRSEC research enables life-saving technology
Yoel Fink (MIT), John Joannopoulos (MIT), Edwin Thomas (MIT)
Technology based on fundamental studies carried out within our MRSEC is
now saving lives at hospitals across the country: over 175 novel
endoscopic surgical procedures per week are being carried out across
250 medical facilities in the U. S. using high-power laser radiation
delivered by OmniGuide photonic fibers.

PREM Collaboration yields scientific and educational results
Robert Smith, Rufina Alamo, and Michael Bockstaller
A collaboration between PREM partners, Michael Bockstaller (CMU) and Rufina Alamo (FAMU) had great outcomes for both science and education. A student from Alamos's group at FAMU, Robert Smith, joined Bockstaller's group during the summer to study the effect of selective chlorine substitution on the crystallization of polyethylene. Scientifically, the collaboration resulted in two publications co-authored by Smith, Bockstaller, Alamo, and others (see figures below). Educationally, Smith's exposure to graduate research at CMU led him to apply for graduate school at CMU and elsewhere.

Grain Boundary Lifetimes
Shen Dillon and Gregory Rohrer
The types of grain boundaries that make up the interfacial network within polycrystalline solids influence the properties and performance of the material. The population of grain boundary types is anisotropic, meaning that some of the types are found more frequently than others.
