Hardness and wear resistance measurements were done also in thermally annealed (200-800 °C) samples revealing the effectiveness of SiC coatings to protect tool material against

Calculations of the total dielectric functions and the optical bandgap energy (OBGE) of 4H-SiC were performed by the full-potential linear muffin-tin-orbital method.. The results

The computational method, for the calculation of the bandgap, full potential linearized augmented plane wave (FPLAPW) method within the density-functional theory and

In this work diamond thin films with small grain size and good size and good quality were obtained in a surface wave-guide microwave discharge, the Surfatron system, with a

The electrochemical behavior has been studied in order to observe the potential window and other parameters con- cerning different active area. The electrochemical responses

With the addition of oxygen to the mixtures containing halogen, the objective is to increase the solubility of the carbon in the gas phase, in the attempt to eliminate the nega-

Microtome cutting under liquid nitrogen was used to separate individual LCP particles from the injection- moulded PPS/LCP composites. Due to the brittleness of the PPS matrix,

The aim of this study was to analyze the microhardness of two resin-modified glass ionomer cements (Vitremer; Fuji II LC); two polyacid-modified composite resins (Freedom; F2000) and
