A method of making carbon sheets comprising nanosized metal particle. The method includes dissolving sodium chloride, a salt containing the metal, and glucose into water, maintaining weight ratio weight of sodium chloride to glucose in the range of 1-8, resulting in a homogeneous aqueous solution. The homogeneous aqueous solution is then dried to form a homogeneous powder which is then heated for a time period resulting in a composite comprising carbon sheets containing the sodium chloride and nanoparticles of the metal. The sodium chloride is removed resulting in carbon sheets containing nanoparticles of the metal. A carbon sheet with 2D morphology containing nanosized metal particles. An electrode comprising a carbon sheet with 2D morphology containing nanosized metal particles. An electrochemical storage cell containing an anode comprising a carbon sheet with 2D morphology containing nanosized metal particles.

Methods of forming a metal-alloy graphene nanocomposites are provided. The methods include providing a graphene substrate and forming a conducting polymer layer on a first major surface of the graphene substrate. The methods also include pyrolyzing the conducting polymer layer to form a nitrogen-doped graphene substrate and dispersing a plurality of metal-alloy nanoparticles on a first surface of the nitrogen-doped graphene substrate to form the nanocomposite.

A lens alignment system and method is disclosed. The disclosed system/method integrates one or more lens retaining members/tubes (LRM/LRT) and focal length spacers (FLS) each comprising a metallic material product (MMP) specifically manufactured to have a thermal expansion coefficient (TEC) in a predetermined range via selection of the individual MMP materials and an associated MMP manufacturing process providing for controlled TEC. This controlled LRM/LRT TEC enables a plurality of optical lenses (POL) fixed along a common optical axis (COA) by the LRM/LRT to maintain precise interspatial alignment characteristics that ensure consistent and/or controlled series focal length (SFL) within the POL to generate a thermally neutral optical system (TNOS). Integration of the POL using this LRM/LRT/FLS lens alignment system reduces the overall TNOS implementation cost, reduces the overall TNOS mass, reduces TNOS parts component count, and increases the reliability of the overall optical system.

A dust core that can significantly reduce the iron loss is provided. The dust core of the present invention includes soft magnetic particles comprising pure iron or an iron alloy and a grain boundary layer existing between adjacent soft magnetic particles. The grain boundary layer has a compound layer comprising M.sub.xFe.sub.2-xSiO.sub.4 (0≤x≤1, M: one or more types of metal elements that serve as divalent cations). Such a dust core is obtained by annealing a compact. The compact is obtained by compression-molding a powder for magnetic cores. In the powder for magnetic cores, coating layers that coat the surfaces of soft magnetic particles are each composed of a composite phase in which spinel-type ferrite represented by M.sub.yFe.sub.3-yO.sub.4 (0≤y≤1, M: one or more types of metal elements that serve as divalent cations) is dispersed on a surface of a silicone resin or inside the silicone resin. The dust core after annealing exhibits a high specific resistance due to the grain boundary layer having the compound layer and can reduce both the eddy-current loss and the hysteresis loss.
