Abstract: In some embodiments, a method receives a context for a user account and selects a plurality of collections for an interface. A collection includes one or more instances of content. The method analyzes a context for a user account to select a theme from a plurality of themes for a collection in the plurality of collections. The themes in the plurality of themes apply different display formats to the collection. The method sends an identifier for the theme and information for the collection to a client device being used by the user account to indicate to the interface the theme to use to display the collection with the plurality of collections.

Abstract: A method of making a fuel grain for use in a rocket motor, the method comprising blending a first energetic nanoscale metallic compound and a second compound suitable to form a feedstock material for use in an additive manufacturing apparatus, the additive manufacturing apparatus operatively connected to a computing system, that provides additive manufacturing printing instructions to the additive manufacturing apparatus, permitting construction of an autonomously designed and optimized rocket fuel grain section; wherein the stochastic deposition simulation-assisted fuel grain geometries further comprise a plurality of agglutinated layers of solidified fuel grain compound, each layer of the plurality of layers comprising a plurality of blended and radially displaced beads of different radii, said radial displacement optionally optimized via competitive simulation programs, and wherein the system continuously mixes constituent materials in an inline/static mixer, with viscosity controlled via particle size var

Abstract: The present disclosure describes a system and method of depositing ceramic or ceramic composite coatings on the inside surface area of a tubular shape. The system and method described herein can provide an interior coating for tubes and pipes to provide wear resistance, abrasion resistance, and anti-scaling effects.
