In accordance with one aspect of the presently disclosed inventive concepts, a metal aerogel includes a plurality of metal nanowires formed into a porous three-dimensional structure, where pores in the structure are anisotropic.
A generative attribute optimization (“GAO”) system facilitates understanding of effects of changes of attribute values of an object on a characteristic of the object and automatically identifying attribute values to achieve a desired result for the characteristic. The GAO system trains a generator (encoder and decoder) using an attribute generative adversarial network. The GAO model includes the trained generator and a separately trained predictor model. The GAO model inputs an input image and modified attribute values and employs the encoder and the decoder to generate a modified image that is the input image modified based on the modified attribute values. The GAO model then employs the predictor model to that inputs the modified image and generate a prediction of a characteristic of the modified image. The GAO system may employ an optimizer to modify the attribute values until an objective based on the desired result is achieved.
A product includes a nanostructure having a core and a shell. The core has a coercive field of at least 3 kOe and the shell has a saturation magnetization of at least 50 emu per gram. A product includes a nanostructure having a core and a shell. The shell has a coercive field of at least 3 kOe and the core has a saturation magnetization of at least 50 emu per gram. A method includes forming core/shell nanostructures and forming millimeter wave absorbers including the core/shell nanostructures and a support structure.
