Abstract: A method for fabricating carbon nanoparticle polymer matrix composites includes the steps of: providing a nanoparticle mixture that includes carbon nanoparticles (CNPs), mixing the nanoparticle mixture and a plastic substrate into a homogenous (CNP)/polymer mixture having an interconnected network of carbon nanoparticles (CNPs); and irradiating the (CNP)/polymer mixture with electromagnetic radiation controlled to form a polymer composite and uniformly consolidate and/or interfacially bond the carbon nanoparticles (CNPs) into the polymer matrix.

Abstract: A method for making concrete and concrete structures includes: providing a liquid admixture with a carbon nanomaterial in a liquid aqueous or organic solvent/compound mixture, mixing the liquid admixture with cement and water in a dosage selected to form a concrete mix having a carbon nanomaterial structure having individual carbon nanomaterial particles with a unit cell overlap, and hardening the concrete mix to form a concrete matrix with the carbon nanomaterial forming a 3-dimensional carbon nanomaterial network incorporated into the concrete matrix. The 3-dimensional carbon nanomaterial network has a shielding effect against high frequency electromagnetic pulses and other radiofrequency signals.

Abstract: A method for making an admixture for concrete includes the steps of providing a carbon nanomaterial comprised of carbon nanoparticles and wetting and dispersing the carbon nanomaterial in a liquid organic solvent/compound mixture comprised of amine based compounds configured to de-agglomerate and uniformly disperse the carbon nanoparticles. The method also includes the step of selecting the organic/solvent compound mixture to perform the wetting and dispersing step and to also perform at least one additional function in a particular type of concrete. An admixture for making concrete comprises a suspension of uniformly dispersed carbon nanoparticles having a predetermined percentage range by mass of the admixture in an organic solvent/compound mixture comprising an amine based compound having a predetermined percentage range by mass of the organic solvent/compound mixture.

Abstract: An electrolyte system suitable for use in an energy storage device (such as a supercapacitor), and energy devices which comprising the electrolyte system which is made up of an ionic liquid, such as Li or EMI TFSI and a stabilising amount of a stabilising additive. The stabilising additive preferably contains nitrile and or aromatic (benzene) groups, and may be advantageously benzonitrile, cinnamonitrile or succinonitrile. The stabilising additive stabilises the energy storage device against ESR rise and/or capacitance loss but does not adversely affect other performance characteristics of the ionic liquid.

Abstract: A generally prismatic package (1) for an electrical device in the form of supercapacitive element (2) having an electrical property with a predetermined value. Package (1) includes an insulating element in the form of a generally rectangular-prismatic liquid crystal polymer (LCP) housing (3) for supporting element (2). More specifically, element (2) is mounted to the insulating element such that, following surface mounting of element (2) to a substrate, in the form of a printed circuit board (not shown), the electrical property remains within a predetermined tolerance.
