The wavelet transform was applied to Raman spectra to remove heteroscedastic noise from ancient pigments such as azurite and ultramarine blue. Wavelets from the Daubechies, Coiflet and Symmlet families were evaluated. Two different thresholding strategies on the detail coefficients were applied; the

## Abstract The Raman spectra of ethanolic solutions of CCl~4~ of different concentrations were measured and de‐noised by the wavelet transform method. The results show that noise can be filtered efficiently without changing the peak positions and the linear relationships between the peak intensity
Bioceramic coatings with defined chemical composition and structure are often needed to satisfy specific biocompatibility properties in the prosthetic field. An example is hydroxyapatite (HA) for coatings, which, according to the Standard Specifications of the ASTM, must be crystalline and have a st
