Abstract: A freshwater harvesting assembly includes a micro-scale component selected from a polymer, a foam, and a membrane; a water-sorption material selected from metal-organic framework (MOF), nanosilica gel, and superabsorbent polymer; wherein the water-sorption material is incorporated within the micro-scale component to thereby provide a water-sorption-material-containing micro-scale component; and a housing carrying the water-sorption-material-containing micro-scale component.

Abstract: A dry adhesive includes a first plurality of fiber segments mechanically interlocked with a second plurality of fiber segments. A dry adhesive can include a first plurality of fibers mechanically interlocked with a second plurality of fibers or a single plurality of fibers having a first end region mechanically interlocked with a second end region. The fiber segments and fibers can be aligned, electrospun nanofibers. One or more continuous and scalable methods of making aligned fibers are also provided. One or more apparatuses are also provided.

Abstract: A dry adhesive including a non-woven fabric of nanofibers comprising a polymeric material. The nanofibers include an average diameter within a range of from 50 nm to 10000 nm, and the non-woven fabric of nanofibers has a thickness within a range of from 0.1 μm to 100 μm. The dry adhesive has a shear adhesion strength that is higher than the normal adhesion strength. Additionally disclosed is a dry adhesive fiber mat including substantially aligned fibers extending lengthwise from a first region to a second region, each of the fibers having a diameter that is less than or equal to 10 microns. The dry adhesive fiber mat is selectively repositionable to, from, and between a mechanically interlocked state wherein the fibers at the first region are intimately positioned within void spaces between the fibers at the second region and a separated state not intimately positioned as such.
