METHOD FOR OBTAINING A GRAPHENE PRODUCT, GRAPHENE PRODUCT AND USE THEREOF

NºPublicación: EP3412626A1 12/12/2018

Solicitante:
EFICIENCIA ENERGETICA APLICADA S L [ES]

Resumen de: EP3412626A1

The invention relates to a method for obtaining a graphene product and to the use thereof, the method being based on thermal mechanical exfoliation of graphite by means of a specifically designed self-rotating screw (2) and balls of material with defined dimensions, the screw being inserted into a leaktight chamber (1) having a controlled environment. The graphite and balls are rotated dry, the balls acquiring high centrifugal force on the internal walls of the leaktight chamber and reaching ideal internal temperatures, so that graphite exfoliation takes place in this zone at nanometric level. The graphene material obtained is extracted and filtered by means of a continuous vacuum system. This method allows the production of a pure homogeneous graphene material and, in turn, selection by sizes, to obtain a material with optimal properties for each type of use.

LOW POWER BIOLOGICAL SENSING SYSTEM

NºPublicación: US2018344186A1 06/12/2018

Solicitante:
ST MICROELECTRONICS INC [US]

Resumen de: US2018344186A1

It is recognized that, because of its unique properties, graphene can serve as an interface with biological cells that communicate by an electrical impulse, or action potential. Responding to a sensed signal can be accomplished by coupling a graphene sensor to a low power digital electronic switch that is activatable by the sensed low power electrical signals. It is further recognized that low power devices such as tunneling diodes and TFETs are suitable for use in such biological applications in conjunction with graphene sensors. While tunneling diodes can be used in diagnostic applications, TFETs, which are three-terminal devices, further permit controlling the voltage on one cell according to signals received by other cells. Thus, by the use of a biological sensor system that includes graphene nanowire sensors coupled to a TFET, charge can be redistributed among different biological cells, potentially with therapeutic effects.
