Abstract: Gas separation membranes as may be used in separating gaseous materials from one another and methods of forming the membranes are described. The separation membranes include polymer-grafted nanoparticles (GNPs) as a platform and a relatively small amount of free polymer. The free polymer and the polymer grafted to the nanoparticles have the same chemical structure and similar number average molecular weights. The gas separation membranes can exhibit high ideal selectivity and can be used in a variety of applications, such as carbon capture.

Abstract: Provided are methods of separating one or more components from a fluid by using membranes and other materials comprising polymer graft nanoparticles arranged in a lattice structure. The disclosed compositions exhibit an increase in selectivity between two penetrants that is greater than the neat polymer selectivity for those penetrants. The compositions also exhibit an increase in selectivity between two penetrants with increasing permeability. Also provided are systems for effecting such separations, systems for agent detection, and additional methods for constructing separation components.

Abstract: The present subject matter relates to a voxel and methods of organizing an object into a three-dimensional (3D) array using the voxel. The voxel can include a plurality of frames including at least one single stranded (ss) DNA motif with at least one free base, wherein the at least one ssDNA motif hybridizes with a complementary strand fragment of other frames.
