Advanced Investigation of the Elimination of Methylene Blue From Wastewater Using Activated Carbon–Copper Oxide Nanowires: New Perspectives With Statistical Physical Modeling

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the actual route of methylene blue (MB) dye adsorption by using fabricated polyfunctional activated carbon–copper oxide nanowires (AC@CuO‐NWs) from bulky wastewater bodies has been investigated. To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical ...

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

Energy Balancing of Electrochemical Alternatives to the Solvay Process

open access: yesChemie Ingenieur Technik, EarlyView.
To overcome the CaCl2 and CO2 emissions custom to the conventional Solvay process in soda ash production, electrochemically based alternatives were investigated. In particular, the mass‐ and energy balances for chlor‐alkali electrolysis and bipolar electrodialysis‐based processes are discussed comprehensively in the presented work.
