Abstract

Material aspects of heterostructural Si/CeO[sub 2], fabricated by magnetron sputtering as buffered substrates for sputtered YBa[sub 2] Cu[sub 3]O[sub 7-x] (YBCO) films, are studied by means of X-ray diffraction, AFM, Raman and SIMS-ToF analysis. Different Si/CeO[sub 2] layouts are chosen and tri-layers Si/CeO[sub 2]/YBCO, grown on the respective bi-layer substrates, are preliminary analyzed. Outstanding material issues suggest that in the framework of sputtering technology, epitaxy is out of reach for Si/CeO[sub 2]/YBCO multi-layers. However, the results point toward the scalability/integrability of the technology with silicon processing when the main target consists of networking for integrated electronics.

Abstract

Micro-Raman spectroscopy (μ-RS) represents an appealing technique in dentistry, allowing the in-vitro detection of analytic structure and molecular composition changes of dental and oral cavity tissues. The gingival crevicular fluid (GCF) is a site-specific inflammatory exudate deriving from the epithelium lining of the gingival sulcus. The GCF analysis is useful in monitoring the factors related to the periodontal changes in response to diseases or mechanical stimuli. Therefore, the analysis of the GCF provides a simple and noninvasive diagnostic procedure to follow-up the periodontal ligament and bone remodeling during the orthodontic tooth movement. In this study, the potentiality of visible light μ-RS to evaluate GCF composition changes in the periodontium due to orthodontic forces was assessed. Sterile paper cones impregnated with GCF were collected from patients before and during an orthodontic treatment with fixed appliances and analyzed by μ-RS. A suitable numerical treatment based on wavelet-based algorithms was performed in order to eliminate the contribution of substrate and background signals on spectral data. The preliminary results showed changes in the secondary structure of Amide I band and an increase of carotenoid content in GCF during the orthodontic treatment.

Abstract

The potential use of micro-Raman spectroscopy for estimating the microstructural changes occurring in periodontal ligaments after orthodontic treatment was explored. An in vitro investigation on bovine ligaments was carried out in order to find the appropriate conditions for studying human cases. The results were compared with preliminary analysis from human samples.
