Summary: Aquatic pollution, including organic debris and heavy metals, poses a serious threat to living organisms. Copper pollution is harmful to humans, and there is a need for effective methods to remove it from the environment. A novel adsorbent, Fr-MMWCNTs-Fe3O4, was developed and characterized in this study. Batch adsorption tests showed that Fr-MMWCNTs-Fe3O4 had a maximum adsorption capacity of 250 mg/g at 308 K and could efficiently remove Cu2+ ions over a pH range of 6 to 8. The results demonstrate the potential of Fr-MMWCNTs-Fe3O4 composites as an efficient adsorbent for removing Cu2+ ions from untreated natural water sources.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.
