摘要： High surface area 3D mesoporous carbon nanocomposites can be derived from Zn dust and PET bottle mixed waste with a high surface area. Simultaneous transformation of Zn metal into ZnO nanoparticles and PET bottle waste to porous carbon materials can be achieved by thermal treatment at preferably 600 to 800° C., and reaction times of from 15 to 60 minutes, after optionally de-aerating the reaction mixtures with N2 gas. The waste-based carbon materials can have surface areas of 650 to 725 m2/g, e.g., 684.5 m2/g and pore size distributions of 12 to 18 nm. The carbon materials may have 3D porous dense layers with a gradient pore structure, which may have enhanced photocatalytic performance for degrading, e.g., organic dyes, such as methylene blue and malachite green. Sustainable methods make ZnO-mesoporous carbon materials from waste for applications including photocatalysis, upcycling mixed waste materials.

摘要： Discussed herein are methods of orienting one-dimensional and two-dimensional materials via the application of stationary and rotating magnetic fields. The oriented one-dimensional and two-dimensional materials may exhibit macroscopic properties, and may be employed in various measurement devices as well as thermal and electrical shielding applications or battery devices. A single 1D or 2D material may be suspended in another material such as dionized water, polymer(s), or other materials during the orientation, and the suspension may remain as a liquid or may be solidified or partially solidified to secure the oriented material(s) into place. The 1D and 2D materials that respond to the magnetic orientation may further cause other elements of the suspension to be oriented in a similar manner.

摘要： A graphite article formed of a creped graphite sheet is provided. The creped graphite sheet has a first major surface and a second major surface oppositely disposed to the first major surface and a plurality of macrofolds, each macrofold having a plurality of associated microfolds, wherein each microfold is smaller than the associated macrofold. The creped graphite article has improved flexibility as compared to a graphite sheet which has not been creped. The creped graphite sheet can be formed of a sheet of flexible natural graphite or a sheet of synthetic graphite.
