摘要： Method for making a liquid foam from graphene. The method includes preparing an aqueous dispersion of graphene oxide and adding a water miscible compound to the aqueous dispersion to produce a mixture including a modified form of graphene oxide. A second immiscible fluid (a gas or a liquid) with or without a surfactant are added to the mixture and agitated to form a fluid/water composite wherein the modified form of graphene oxide aggregates at the interfaces between the fluid and water to form either a closed or open cell foam. The modified form of graphene oxide is the foaming agent.

摘要： A methodology for designing structured metamaterials that can reflect, absorb and focus the propagation of both scalar acoustic and vector elastic waves is described. Three exemplary representative inventions based on the disclosed invention are described, illustrating i) compact ultra-wide broadband isolation, ii) sub-wavelength gaps and negative index propagation utilizing a single material platform, and iii) a fundamentally new method of producing multiple high frequency spectral gaps. Such metamaterial designs possess a wide range of potential applications, ranging from but not limited to, isolating an entity from external mechanical or acoustical vibrations, compact focusing lenses as well as cascaded high frequency filters for wave shaping and nonlinear wave propagation control.
