To make paper, machines spray wet pulp on a moving screen and extract the water from it by squeezing it between rollers, before drying it using heat and rolling it on reels as finished product. The water extracted in the squeezing process is removed by a continuous roll of fabric called a felt. There are typically three felts on a paper machine. Felts wear out over time, and therefore must be r...

In this paper, the performance of Fe-based redox flow batteries (IRFBs) was dramatically improved by coating N-doped carbon spheres (NDCS) on graphite felt electrodes. NDCS synthesized single-step hydrothermal method using dextrose and ammonia as a precursor coated over electrodes electrostatic spraying. The weight required for modification electrode to achieve effective battery studied electro...

The recent decades have witnessed a booming research effort on the development of highly active electrode materials in electrocatalysis with aim to replace commonly used noble metal-based ones. Although non-noble metal electrodes can fulfill some requirements terms performance and price, their stability alkaline media is generally weak. Additionally, from environmental view point, use metals ca...
