Program Highlights for year 2009
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
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.
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.
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.
One of the challenges in developing robust multilayers is the need to predict the interfacial strength between hard and soft materials.
A physical hypothesis based on theory and ab initio modeling for the stamping of graphene and few layers graphene (FLG) on silica is presented, and the feasibility of site-specific stamping of FLG patterns is demonstrated experimentally (figure below shows 10-layer FLG pattern stamped on silica).
Mr. Chin-Yi Liu, a graduate student working in Professor Kortshagen’s group, demonstrated the first hybrid solar cell based on silicon nanocrystals and a conductive polymer, poly-3(hexylthiophene) (P3HT).
