Critical slowing of the spin and charge density wave order in thin film Cr following photoexcitation
Sheena K. K. Patel, Oleg Yu. Gorobtsov, Devin Cela +11
We report on the evolution of the charge density wave (CDW) and spin density wave (SDW) order of a chromium film following photoexcitation with an ultrafast optical laser pulse. Th…
Operando real-space imaging of a structural phase transformation in a high-voltage electrode
Yifei Sun, Sunny Hy, Nelson Hua +5
Discontinuous solid-solid phase transformations play a pivotal role in determining properties of rechargeable battery electrodes. By leveraging operando Bragg Coherent Diffractive…
Proton distribution visualization in perovskite nickelate devices utilizing nanofocused X-rays
Ivan A. Zaluzhnyy, Peter O. Sprau, Richard Tran +17
We use a 30-nm x-ray beam to study the spatially resolved properties of a SmNiO-based nanodevice that is doped with protons. The x-ray absorption spectra supported by density-f…
In-situ 3D Imaging of Catalysis Induced Strain in Gold Nanoparticles
Andrew Ulvestad, Kiran Sasikumar, Jong Woo Kim +9
Multi-electron transfer processes, such as hydrogen and oxygen evolution reactions, are crucially important in energy and biological science but require favorable catalysts to achi…
X-ray Reflectivity Studies of Atomic-level Surface-segregation in a Liquid Eutectic Alloy of AuSn
Venkatachalapathy S. K. Balagurusamy, Reinhard Streitel, Oleg G. Shpyrko +3
X-ray reflectivity studies reveal atomic-level surface-segregation at the free surface of the eutectic Au71Sn29 liquid alloy. The surface-segregation extends up to three layers, in…
Crystalline Surface Phases of the Liquid Au-Si Eutectic Alloy
Oleg G. Shpyrko, Reinhard Streitel, Venkatachalapathy S. K. Balagurusamy +6
A two dimensional crystalline layer is found at the surface of the liquid eutectic AuSi alloy above its melting point C. Underlying this crystalline…
