Mechanics of crack deflection at a twist grain boundary

Research

  Heterogeneous brittle solids such as ceramics, lamellar intermetallics, and  olycrystalline hexagonal-close-packed (hcp) metals such as Zr, Zn and Cd are   echnologically important and broadly used. Zirconium, for example, has a low  bsorption cross section for neutrons, and is therefore used in nuclear energy pplications. Titanium aluminide (TiAl) is a candidate material for many

Multiple States of Nanoring Magnetic Tunnel Junctions

Research

Background: The geometry of a nanoring magnet provides unique magnetic configurations of onion, vortex, and twisted, which can be exploited in nanoring magnetic tunnel junctions (NRMTJs) .

Granular materials in a Hele-Shaw Cell

Research

A Hele-Shaw system was used by University of Chicago MRSEC researchers, Sidney Nagel and Heinrich Jaeger and their research groups, to explore the zero-surface-tension properties of granular "fluids."Â’  Theoretically, it was determined by Paul Wiegmann, also at the

Charge transport in arrays of multicomponent nanostructures

Research

Researchers, Dmitri Talapin and collaborators, at the University of Chicago MRSEC have been studying electronic properties of new nanoscale materials consisting of both magnetic and semiconducting components (FePt and PbS).Â’  These components are integrated into i

Green Chemistry of Poly(l-lactides)

Research

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.
