News & Highlights

 

  • Nesterov photoEvgueni Nesterov's research on organic polymer thin films was featured in LSU's The Daily Reveille on November 8, 2017, and its online counterpart LSUNow.com. The article discussed Nesterov's work on synthesizing solar cells that could increase the quality of light-emitting devices and potentially revolutionize the electronics industry. The U.S. Department of Energy, Office of Science, Basic Energy Sciences division highlighted this research in an October 2017 press release.

  

  • Nature Materials imageLaCNS researchers published their findings of a new magnet with nearly massless charge carriers in Nature Materials (online) in July 2017. Led by Professor Zhiqiang Mao, researchers at Tulane University and LSU, in collaboration with scientists from Oak Ridge National Laboratory, National High Magnetic Field Laboratory at Tallahassee and Los Alamos, and the Chinese Academy of Sciences, discovered a new magnet with nearly massless charge carriers. This observation of topological behavior, where charge-carrying electrons behave as if they have no mass, suggests that it may be an example of the long sought-after Weyl semimetal caused by time-reversal symmetry breaking. The recent discoveries of topological materials — a new class of relativistic quantum materials — hold great promise for use in energy saving electronics. Read article here

  • Dr. Zhiqiang Mao’s group at Tulane ran an experiment on Ir-doped ruthenates with HB1A (triple-axis spectroscopy) at ORNL on March 10-17, 2016, in collaboration with Ke at MSU. They completed inelastic neutron scattering measurements on Fe-doped Sr2RuO4 in January 2016. They also recently collaborated with Pengchen Dai's group in neutron scattering measurements on iron chalcogenide superconductors under pressure (beamline HB1). They also have a few other planned experiments which will use their samples in spring 2016.

  • Dr. Mao is also collaborating with Collin Broholm at Johns Hopkins. He has a planned polarized neutron scattering experiment (MACS) at NIST from April 27 to May 5-7, 2016. This experiment will focus on magnetic excitation measurements on optimally doped iron chalcogenide superconductors. 

  • U.S. Department of Energy awards LaCNS a $4.9M Statewide Research Grant. LaCNS researchers will use the equipment and facilities and collaborate with the scientific staff at Oak Ridge National Lab in Tennessee, where they will run their experiments.

  • Prof. Evgueni Nesterov visited Institut Laue-Langevin (ILL) in Grenoble, France, where he presented a seminar describing the LaCNS efforts to create a neutron scattering center in Louisiana. He also met with ILL director, Dr. William Stirling, and ILL scientists, and discussed possibilities for mutual collaborations between Louisiana and ILL scientists in the areas of using neutron scattering to study soft materials systems.

Garrett Sternhagen in Donghui Zhang’s group will prepare a series of sequence-specific peptoid amphiphiles using automated synthesizer at the Foundry facility. These molecules will serve as model systems in the study of charge-charge interactions in the micellar assemblies of peptoid amphiphiles in solution. The structure and dynamic of the assemblies will be investigated by elastic and inelastic neutron scattering. These studies in conjunction with computational modeling will provide insights into how the charge placement and density in space influence the structure and dynamics of mesoscale assemblies.
