Rechargeable, all-solid-state Li ion batteries (LIBs) with high specific
capacity and small footprint are highly desirable to power an emerging
class of miniature, autonomous microsystems that operate without a
hardwire for power or communications. A variety of three-dimensional
(3D) LIB architectures that maximize areal energy density has been
proposed to address this need. The success of all of these designs
depends on an ultrathin, conformal electrolyte layer to electrically

Submitted by Jianyu Huang on Wed, 2011-06-15 17:55.PRL 106, 248302 (2011) The atomic scale lithiation mechanism of individual SnO2 nanowires in a flooding geometry was revealed by in situ transmission electron microscopy. The lithiation was initiated by the formation of multiple stripes with a width of a few nanometers parallel to the (020) plane traversing the entire wires, serving as multiple reaction fronts for later stages of lithiation. Inside the stripes, we identified a high density of dislocations and enlarged interplanar spacing, which provided an effective path for lithium ion transport.

Surface mediated plasticity in sub-10-nm-sized gold crystals
Submitted by Jianyu Huang on Tue, 2010-12-21 16:54.
Although deformation processes in submicron-sized metallic crystals are
well documented, the direct observation of deformation mechanisms in
crystals with dimensions below the sub-10-nm range is currently lacking.
Here, through in situ high-resolution transmission electron
microscopy (HRTEM) observations, we show that (1) in sharp contrast to
what happens in bulk materials, in which plasticity is mediated by
dislocation emission from Frank-Read sources and multiplication, partial
dislocations emitted from free surfaces dominate the deformation of

Dislocation migration in carbon onions
Submitted by Jianyu Huang on Sat, 2010-09-04 13:07.Phys. Rev. Lett. 105, 106102 (2010)
What does a dislocation look like in a spherical geometry, and how does it migrate in such a structure? We report here the counterintuitive motion of the 1/2⟨0001⟩ edge dislocation in carbon onions from the outer surface to the inner core, i.e. from a low pressure surface to a high pressure core, rather than from the core to the surface as expected due to a surface image force. Maybe you can help us to explain this peculiar phenomenon.
