Uncovering the tension-compression asymmetry of low stacking fault FCC alloys...
A certain type of alloys, with face-centered-cubic (FCC) structure and medium to low stacking fault energies (SFE), can trigger the formation of multiple twins (mechanical... -
In-situ Neutron Diffraction Studies of Lithium Battery Materials
This proposal seeks to test a new battery designed to allow in situ neutron diffraction measurements of lithium ion battery electrodes under charge and discharge. We have... -
Determining the Hamiltonian of a New Quantum Spin Ice Material
Pr2Hf2O7 is a potential quantum spin ice compound. Compared to the classical spin ice ions Ho3+ and Dy3+, Pr3+ has weaker Ising anisotropy and significant XY terms leading to...
