摘要:
The present invention relates to a sensor for an electronic tongue or nose for analysing a sample or detecting a target. The sensor comprises a support, on one surface of which a plurality of sensitive areas are located, each sensitive area comprising at least one receptor and being capable of transmitting a measurable signal generated by the interaction of at least one constituent of the sample or one target with at least one receptor. The sensor is characterised in that it comprises at least three sensitive areas that differ from one another in terms of their respective receptor compositions, at least one of the sensitive areas comprising a mixture of at least two different receptors, while the two other sensitive areas each comprise at least one of the two receptors.
摘要:
The present invention relates to a method for building up metal turbomachine components made of aluminium using a MIG welding apparatus comprising a pulsed‑current generator and a pulsed feed of metal filler wire, said method being characterized in that said building up is performed using a metal filler wire the composition of which is of the same nature as the composition of the aluminium alloy of said component being built up, said pulsed feed of metal wire and the rate at which said metal turbomachine component is built up being adapted in such a way as to achieve build up without cracking in the hot state.
摘要:
The electronic component (2) comprises at least two superposed conductive or semiconductor layers (4;10,12;14,16). According to one aspect of the invention, the component comprises at least one graphene layer (8) interposed between the conductive or semiconductor layers (4;10,12;14,16), the conductive or semiconductor layers (4;10,12;14,16) being electronically coupled through the thickness of the or each graphene layer (8). Applications especially include magnetic tunnel junctions or spin valves, memristors, etc.
