Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

A nitrogen-containing porous carbon material, and a capacitor and a manufacturing method thereof are provided. A carbon material, a macromolecular material and a modified material are mixed into a preform. The modified material includes nitrogen. A formation process is performed on the preform to obtain a formed object. High-temperature sintering is performed on the formed object to decompose and remove a part of the macromolecular material, while the other part of the macromolecular material and the carbon material together form a backbone structure including a plurality of pores. As such, the nitrogen becomes attached to the backbone structure to form a hydrogen-containing functional group to further obtain the nitrogen-containing porous carbon material. The nitrogen-containing porous carbon material may form a first nitrogen-containing porous carbon plate and a second nitrogen-containing porous carbon plate, which are placed in seawater to form a storage capacitor for seawater.
