Hyper-Raman scattering from vitreous boron oxide: coherent enhancement of the boson peak

open access: yes, 2005
Hyper-Raman scattering spectra of vitreous B$_2$O$_3$ are reported and compared to Raman scattering results. The main features are indexed in terms of vibrations of structural units.

Evidence for Two Superconducting Gaps in $MgB_2$

open access: yes, 2001
We have measured the Raman spectra of polycrystalline MgB$_{2}$ from 25 {\cm} to 1200 {\cm}. When the temperature was decreased below the superconducting transition temperature $T_c$, we observed a superconductivity-induced redistribution in the ...

Classifying Raman Spectra of Colon Cells by Principal Component Analysis—Linear Discriminant Analysis and Partial Least Squares—Linear Discriminant Analysis Methods

open access: yesApplied Sciences
Colorectal cancer is one of the most commonly diagnosed cancers in developed countries. Although the gold-standard diagnosis technique is the histological analysis of colon biopsies, it is important to investigate different diagnostic tools because the ...

Surface Enhanced Raman Scattering of p-(Dimethylamino) Cinnamic Acid on Silver and Silver-Gold Alloids [PDF]

open access: yes, 2014
Through this experimental work we describe assignments for the Raman and surface-enhanced Raman scattering (SERS) spectra (on Ag and Ag(x)-Au(1-x) colloids) of 4-(dimethylamino) cinnamic acid (DMACA).
