    摘要: Materials and methods for implementing engineered aggregates in metamaterials are provided. The engineered aggregates may be tuned to oscillate resonantly under the influence of an external force improving the dynamic performance of the metamaterial by impeding dynamic excitation. The engineered aggregate generally comprise a multilayer resonant structure having at least a relatively heavy inner core surrounded by at least a compliant coating layer. The geometry and stiffness of the relative layers can be tuned to engineer a desired resonant frequency response within the aggregate for a chosen frequency range. The engineered aggregates are disposed in a matrix material to form a metamaterial. The engineered aggregates may be disposed within a mortar matrix to form a concrete metamaterial suitable for use, for example, in structural applications, including bunkers, shelters, etc.

    摘要: Exemplary embodiments provide materials and methods for forming CNTs-polymer composites (e.g., CNTs-SBR latex nano-composites and/or CNTs-epoxy nano-composites), CNTs-polymer concrete, and CNTs-polymer modified cementitious composites. In one embodiment, a plurality of CNTs and a surfactant-containing polymer, including a surfactant attached to a polymer chain, can be dispersed within a cementitious matrix to form a CNTs-polymer modified cementitious composite with the surfactant non-covalently bonded to one or more CNTs.

    摘要: Methods of creating degradable particulates in a subterranean environment. The methods provide a degradable material supercritical fluid mixture that comprises degradable material into a wellbore penetrating a subterranean formation and provide an orifice between the wellbore and the subterranean formation wherein the pressure in the subterranean formation is less than the pressure in the wellbore. The degradable material supercritical fluid is then fed through the orifice into the subterranean formation such that the degradable material supercritical fluid mixture expands through an orifice into the lower subterranean formation and particulates are formed.
