[LA-SiGMA] LASiGMA Seminar Today - Dr. Brian Sales, 3:30pm at Louisiana State University

[shelley lee]

Dear All,

 

As a reminder, Dr. Brian Sales of Oak Ridge National Laboratory will be
giving a seminar today at 3:30pm in 1008B at the Digital Media Center at the
Louisiana State University. The title of his talk is "Surprises in Material
Physics."

 

Abstract:

One of the joys of experimental material physics is the discovery of
something new and unexpected. This presentation will discuss some of my
group's recent research that led to several surprising results. The
surprises range from a giant Seebeck coefficient in CrSb2, to the
observation that BaFe2As2 is not tetragonal at room temperature.

 

Our group does science driven synthesis of new materials, often as single
crystals. Most of our recent research has focused on interesting
relationships among magnetism, superconductivity and thermal conductivity.
For example, in some materials magnetic excitations can carry substantial
amounts of heat, while in others they may be responsible for
high-temperature superconductivity.  After providing a brief overview of my
group's research, I will discuss three topics: (1) the use of nanoscale
structural and L-edge spectroscopy on a large number of Fe-based
superconductors (2) the properties of CrSb2, a quasi-1d antiferromagnetic
semiconductor and (3) the use of thermal conductivity measurements near Tc
as a screening tool for magnetically mediated superconductors. This research
is supported by the Department of Energy, Basic Energy Sciences, Materials
Sciences and Engineering Division.

 

Biography:

Brian Sales has over thirty years of experience with the synthesis, and
characterization of unusual electronic and magnetic materials, particularly
those involving rare-earth elements. Dr. Sales has received awards from the
U. S. Department of Energy, IR-100, and Science Digest and he was named the
1985 Inventor of the Year and 2007 Distinguished Scientist of the year at
ORNL. Dr. Sales has authored more than 300 papers, six patents and five book
chapters. His work has been cited more than 13,000 times and his current h
number is 60. Thirty of his papers have each been cited more than 100 times.
Nine of the papers are on new thermoelectric materials, thirteen on high Tc
superconductivity, three on correlated electron materials, two on
oscillatory catalytic reactions, and one on low dimensional magnetism,
batteries, and nuclear waste storage. Of the thirty papers Sales was either
the first or primary author on eleven. Sales has also worked on materials
for the disposal of high-level nuclear waste and developed techniques for
measuring the intermediate range order in phosphate glasses. Sales was made
an ORNL Corporate Fellow in 2012.
