Biological 3D Structures by Cryo-EM: Challenges in Computations and Instruments
23 Oct 2019 | | Contributor(s):: Wen Jiang
Single particle cryo-EM is revolutionizing structural biology. Many structures of viruses and protein complexes have been determined to 2-4 Å resolutions. While stable structures that can be expressed/purified in large quantities can be solved routinely, the dynamic compositions and...

Ferroelectric Domain Structure of La-modified Lead Titanate Ceramics
14 Dec 2018 | | Contributor(s):: Brian Demczyk, G. Thomas
Presentation describes the ferroelectric domain structure of Lanthanum-modified lead titanate ceramics, as deduced by transmission electron microscopy, including the ferroelectric to paraelectric phase transformation. A significant result was the observation of a minimum grain size for...

Ferroelectric Domain Motion
07 May 2018 | | Contributor(s):: Brian Demczyk
Videos show total ferroelectric domain disappearance in bulk La-doped lead titanate, and incomplete reversal in a small (< 0.5 micrometer) grain, when heated through the Curie point.
Magnetic Domain Reversal
Videos show magnetic domain disappearance and reappearance in a Co-22% Ct thin film when heated/cooled through the Curie Point.

Structure and Morphology of Silicon-Germanium Thin Films
07 Feb 2015 | | Contributor(s):: Brian Demczyk
This presentation describes the growth of (Si,Ge & SiGe) thin films on Si and Ge (001) and (111) substrates by ultrahigh vacuum chemical vapor deposition (UHVCVD). Thin films were characterized structurally by conventional and high-resolution transmission electron microscopy (TEM) and...

Evolution of Microstructure and Magnetic Properties in CoCr Thin Films
19 Mar 2014 | | Contributor(s):: Brian Demczyk, J. O. Artman
This presentation describes the structural and magnetic properties, including domain structures, in magnetron-sputtered Co-25% Cr thin films.
Structure and Properties of Carbon and Boron Nitride Nanotubes
10 Jan 2014 | | Contributor(s):: Brian Demczyk
This presentation describes structure and mechanical property determinations on carbon and boron nitride (sp2-bonded) nanotubes , as deduced by transmission electron microscopy.
Structure and Morphology of Silicon Germanium Thin Films
30 Dec 2013 | | Contributor(s):: Brian Demczyk
Single layer silicon and germanium films as well as nominally 50-50 silicon-germanium alloys were deposited on single crystal silicon and germanium (001) and (111) substrates by ultrahigh vacuum chemical vapor deposition. These films spanned the range of + 4 % film-substrate lattice mismatch. A...
