Hybrid silica-based coatings with tetraethoxysilane (TEOS), methyltrietoxysilane (MTES), hydroxyethyl-methacrylate (HEMA) and methacrylopropyl-trimethoxysilane (γMPS) as precursors, were employed to improve the performance ...

We study the mechanical properties of Cu thin films on Si (100) by performing nano-indentation using an atomic force microscopy. Cu films with thickness of 0.3 μm, 1 μm and 2 μm were analyzed. Area profile studies let us ...

The mechanical properties of hard and soft wheat cultivars at different structural-levels were evaluated at 10% and 15% moisture content by AFM, IIT and compression test. Nano and micro-indentation tests revealed that ...

The aim of this study was to evaluate the effect of different drinks on the surface properties of the commercial resin composite Charisma cured by a light emitting diode (LED). Hardness, adsorption of components on the ...

Objective: To investigate the presence of non-infiltrated, partially demineralized dentin (PDD) beneath the hybrid layer for self-etch adhesive systems, and its effect on micromechanical behavior of dentin-adhesive interfaces ...

The coatings obtained by thermal spraying can present a large variety of geometrical parameters (thickness, roughness...), of microstructures (constituents, nature of phases...), of mechanical properties (hardness, elastic ...
