Young's modulus, hardness and fracture toughness of highly ordered nanoporous alumina (PAA) were measured by nanoindentation and Vickers microindentation. A finite element model that accounts for the anisotropy and the pores was developed to extract the Yo ...
The procedures followed to produce Y2O3-dispersed EUROFER 97 powder ready to be compacted and hot isostatic pressing processed are reported. An attrition mill has been used under controlled conditions. The compositional and microstructural characterization ...
Many genomic assays rely on a distance-dependent interaction between luminescent labels, such as luminescence quenching or resonance energy transfer. We studied the interaction between electrochemically excited Ru(bpy) 3 2+ and Cy5 in a hybridization assay ...
The do bias field. dependence of the dielectric loss in SrTi03 thin films deposited onto MgO substrate is investigated. The experimental data obtained at different frequencies of the ac field (8 and 16 GHz) from differently processed films (as deposited an ...
The piezoresistive effect of thick-film resistors has found widespread application in pressure and force sensors due to their high strain-sensitivity, stability and low-cost. The main material requirements for these applications are a high piezoresistive r ...
Magneto-optical Kerr effect, is used to investigate the magnetization of film made of uncoalesced cobalt and cobalt-platinum nanocrystals. For the pure cobalt nanocrystals, different film morphologies are obtained through application of magnetic field duri ...
Diffusion Brazing (DB) of nickel-based superalloys is a standard joining process widely used in gas turbine industry. The DB technique uses a low melting nickel-based filler material, which contains a rapidly diffusing melting point depressant (MPD) such a ...
Al-Cu matrix composites with a high volume fraction of alumina particles (41-62%) prepared by gas-pressure infiltration are characterized in tension and chevron-notch fracture testing before and after heat-treatment. Their mechanical behaviour is shown to ...
An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
NOVELTY - Production of a component (23) coated with a heat protection layer (21) and having a high thermal load capacity comprises applying an adhesion layer (22) containing aluminum on the surface of the component, and applying the heat protection layer ...
