Many of the key technological problems associated with alternative energies (e.g., thermoelectrics, advanced batteries, hydrogen storage, etc.) may be traced back to the lack of suitable materials. …Read more.

Marie-Charlotte Renoult, Université de Rouen, Free falling jets of a viscoelastic solution Wed. November 23rd, 2016
12:45 pm-1:45 pm

Title: Free falling jets of a viscoelastic solution
Prof. Marie-Charlotte Renoult
Université de Rouen, France
Abstract:
We conducted free falling jet experiments of a Newtonian solution with a polymer additive, i.e., a viscoelastic solution.Viscoelastic jets usually break up with the formation of beads-on-a-string (BOAS) structures, where large beads are connected by thin threads. …Read more.

Keji Lai, Univ of Texas, Austin/Microwave Imaging of Edge States and Electrical Inhomogeneity in 2D Materials Mon. November 21st, 2016
12:45 pm-1:45 pm

The understanding of various types of disorders in 2D materials, including dangling bonds at the edges, defects in the bulk, and charges in the substrate, is of fundamental importance for their applications in electronics and photonics. …Read more.

Salah Eddine Boulfelfel, Georgia Institute of Technology, Atomic-Scale Modeling of Activated Processes in the Solid State Mon. November 14th, 2016

In the practice of solid-state chemistry, processes either thermally-activated or induced by external high-pressure are common events. …Read more.

Jim Andrews, Youngstown State University, Coherent Perfect Polarization Rotation–Beyond the Anti-Laser Mon. November 7th, 2016
12:45 pm-1:45 pm

We describe the distinguishing characteristics of coherent perfect optical conversion processes using two-beam interference, as compared to single-beam ‘critical coupling’ processes.  We extend the application of two-port coherent conversion processes to magneto-optical (Faraday) rotation in structured systems and present our recent laboratory demonstration of coherent perfect polarization rotation (CPR) which is a conservative, reversible counterpart to coherent perfect absorption (CPA, or the so-called ‘anti­laser’).  …Read more.

Topological defects (TDs) appear almost unavoidably in continuous symmetry breaking phase transitions [1]. …Read more.

Patrick Woodward, The Ohio State University, The magnetism of double perovskites containing osmium and rhenium Mon. October 24th, 2016
12:45 pm-1:45 pm

 
Patrick M. Woodward
Department of Chemistry and Biochemistry, The Ohio State University
Over the past several years we have been synthesizing and studying the magnetic properties of A2MOsO6 and A2MReO6 (Mg, Zn, Cr, Fe, Co, Ni) double perovskites in a quest to understand how the sign and strength of the superexchange interactions change as a function of the relative filling of the 3d and 5d orbitals, as well as the geometry of the crystal structure. …Read more.

Nayana Shah, University of Cincinnati, Manifestations of spin-orbit coupling and topology in out-of-equilibrium hybrid superconducting systems Mon. October 10th, 2016
12:45 pm-1:45 pm

Recently there has been a lot of excitement generated by the possibility of realizing and detecting Majorana fermions within the arena of condensed matter physics and its potential implication for topological quantum computing.  …Read more.

Zhaoning Song, University of Toledo,The Formation and Degradation of Metal Halide Perovskites Mon. September 26th, 2016
12:45 pm-1:45 pm

Solar cells based on organic-inorganic metal halide perovskite materials, such as methylammonium lead iodide (CH3NH3PbI3), have been the subject of intense investigation during the past 5 years due to high power conversion efficiencies (>22%) and relatively low manufacturing costs. …Read more.
