Ion Irradiation Induced Leaching Property Changes of Borosilicate Glass

He huaxue yu fangshe huaxue, 2023
In the process of deep geological disposal of high-level radioactive waste, the strong radiation field caused by the decay of radionuclides can lead to the leaching property changes of the waste glass. In this work, the 15 MeV Si ion irradiation was used

Effect of the Duty Cycle of Flower-like Silver Nanostructures Fabricated with a Lyotropic Liquid Crystal on the SERS Spectrum

Molecules, 2021
Surface-enhanced Raman scattering (SERS) has been widely reported to improve the sensitivity of Raman spectra. Ordinarily, the laser is focused on the sample to measure the Raman spectrum.

Raman spectrum of CrI3 : An abinitio study [PDF]

Physical review B, 2018
We study the Raman spectrum of CrI$_3$, a material that exhibits magnetism in a single-layer. We employ first-principles calculations within density functional theory to determine the effects of polarization, strain, and incident angle on the phonon ...

Lattice dynamics and Raman spectrum of BaZrO3 single crystals [PDF]

Physical review B, 2019
BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an intense Raman spectrum with sharp and well-defined features.
