A metal oxide macroscopic fiber and a preparation method thereof, the method including: adding, as a spinning dope, an anionic metal oxide aqueous colloidal solution into wet spinning equipment, extruding the spinning dope from the spinning equipment into a thread, injecting the extruded thread into a coagulating bath containing a flocculating agent to obtain as-spun fiber, and repeatedly washing the resulted as-spun fiber with deionized water and drying same, thereby obtaining a metal oxide fiber. Said method makes the process simple and controllable, being adaptable to production on a large scale. The prepared metal oxide fiber having special physical and chemical properties is widely applicable in terms of intelligent spinning, biomedicine, energy recycling and conversion, and the field of microelectronic devices and the like.

A method for synthesizing silica nanofibers using sound waves is provided. The method includes providing a solution of polyvinyl pyrrolidone, adding sodium citrate and ammonium hydroxide to form a first mixture, adding a silica-based compound to the solution to form a second mixture, and sonicating the second mixture to synthesize a plurality of silica nanofibers having an average cross-sectional diameter of less than 70 nm and having a length on the order of at least several hundred microns. The method can be performed without heating or electrospinning, and instead includes less energy intensive strategies that can be scaled up to an industrial scale. The resulting nanofibers can achieve a decreased mean diameter over conventional fibers. The decreased diameter generally increases the tensile strength of the silica nanofibers, as defects and contaminations decrease with the decreasing diameter.

A process for making a mechanically strong, high permeance, and relatively inexpensive support structure for zeolite membranes is described. In an example implementation, a process includes forming a silica powder from silica fibers, mixing the silica powder and a polymer solution to form a mixture, forming the mixture into a shaped mixture, and sintering the shaped mixture to form a silica support.

Lithium-containing nanofibers, as well as processes for making the same, are disclosed herein. In some embodiments described herein, using high throughput (e.g., gas assisted and/or water based) electrospinning processes produce nanofibers of high energy capacity materials with continuous lithium-containing matrices or discrete crystal domains.
