Abstract: At least one embodiment relates to an air purifying machine comprising at least one housing and a plurality of cores wherein each core is disposed in the housing. There is also at least one fan disposed in the housing. In addition, there is at least one pump disposed in the housing, wherein the pump is configured to circulate a fluid inside of the housing. The cores comprise at least two cores disposed inside of the housing comprising a first core and a second core, wherein the second core is disposed inside of said first core and wherein the second core is not concentric with the first core. The non-concentric nature of the cores creates a compression location at a point where the two cores are disposed closest to each other. This compression location creates a higher-pressure location for air flow around the cores.

Abstract: The present invention relates to gels and processes for making bundles of aligned ceramic nanofibers, ceramic nanostructures made by such processes, and methods of using such ceramic nanostructures. Such process is templated via block copolymer self-assembly but does not require any post processing thermal and/or solvent annealing steps. As a result, such process is significantly more efficient and scalable than other processes that are templated via block copolymer self-assembly. The resulting fibers are aligned according to the direction of deposition, making steps where individual fibers are bundled unnecessary.
