TL;DR: In this article, the infrared and Raman spectra of gels obtained from specially prepared solutions of Si(OC2H5)4 (TEOS) which have been thermally treated in the 40-800°C temperature range, are reported and discussed with reference to the spectrum of fused quartz, showing that the gel to glass transformation is an hydrolytic polycondensation process, which takes plase gradually and is practically completed in the samples treated at 800°C.

TL;DR: The novel PCL/PLLA composite scaffolds showed promise whenever tuneable porosity, controlled degradability and guided cell-material interaction are simultaneously requested, and were obtained by synergistic use of phase inversion/particulate leaching technique and filament winding technology.

TL;DR: In this article, the efficiency of carbonate substitution in carbonated hydroxyapatites appropriately synthesized by a modified version of old hydrothermal methods, to obtain an increase of carbonates inside the lattice was determined by carbon elemental analysis, IR spectroscopy and thermal analysis and the results obtained were compared.

TL;DR: This study was aimed at comparing the wear performances of clinically available acetabular liners (Zimmer Inc.) made of electron beam XLPE and conventional UHMWPE, and found significant differences between the wear behaviours of the two sets ofacetabular cups.

TL;DR: In this paper, a continuous evolution of silica gel structure toward that of v-SiO 2 was verified by Raman spectroscopy, and the effect of the H 2 O/TEOS molar ratios on the local structure and the sintering process of the gel was investigated.
