Solicitante:

RAFIEE ROHAM [IR]

Resumen de: US2021108093A1

The present invention discloses a nanocomposite coating composition and coating method for antenna reflector. The nanocomposite coating composition comprises a polymer matrix resin and a plurality of graphene nanoparticles. A portion of hardener is firstly added into epoxy resin system. The plurality of graphene nanoparticles is added to acetone solvent and dispersed using an ultrasonic disperser. An appropriate amount of prepared epoxy resin is added to the mixture of graphene and acetone solvent and stirred using a mechanical stirrer for certain period. The sonication process is applied to the graphene incorporated resin mixture for a duration of about 30-120 minutes. The acetone in the mixture is removed using a magnetic stirrer and a vacuum oven. Further, the remainder of the hardener is added to the mixture and degassed using vacuum oven to form the nanocomposite coating composition. The nanocomposite coating composition converts an electromagnetically insulated antenna into an electromagnetically conductive antenna for enhancing one or more electromagnetic characteristics of the antenna reflector.

Resumen de: US2021108098A1

The present invention relates to preparation and use of nanocellulose fibrils or crystals such as disintegrated bacterial nanocellulose, tunicate-derived nanocellulose, or plant-derived nanocellulose, together with carbon nanotubes, as a biocompatible and conductive ink for 3D printing of electrically conductive patterns. Biocompatible conductive bioinks described in this invention were printed in the form of connected lines onto wet or dried nanocellulose films, bacterial cellulose membrane, or tunicate decellularized tissue. The devices were biocompatible and showed excellent mechanical properties and good electrical conductivity through printed lines (3.8·10−1 S cm−1). Such scaffolds were used to culture neural cells. Neural cells attached selectively on the printed pattern and formed connective networks. The devices prepared by this invention are suited as bioassays to screen drugs against neurodegenerative diseases such as Alzheimer's and Parkinson's, study brain function, and/or be used to link the human brain with electronic and/or communication devices. They can also be implanted to replace neural tissue or stimulate guiding of neural cells. They can also be used to stimulate the heart by using electrical signaling or to repair myocardial infarction and/or damage related thereto.
