Optimization of F¯ Removal From Wastewater Utilizing Alternating Current Electrocoagulation Coupled With Sonication Using a Statistical Design Approach

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Combining electrochemical and advanced oxidation processes (AOPs) has greatly mitigated the limitations of electrocoagulation (EC) in water treatment. This study examined the effectiveness of sonolysis (US)‐assisted alternating current (AC)–EC in reducing fluoride (F¯) from landfill leachate wastewater (LLW), with measurements of electrical ...

A Mouse Model of Depression‐Tumor Multimorbidity Reveals the Mechanism of Tumor Growth Accelerated by Depression

open access: yesAnimal Research and One Health, EarlyView.
Depression accelerates tumor growth by dysregulation of tumor immune microenvironment. (A) Modeling methods: Subcutaneous tumor models were established under chronic unpredictable mild stress conditions, including cold swimming, physical restraint, and food/water deprivation, leading to increased tumor growth.
