Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Examining the Relationship Between Identity Disturbance, Body Image Disturbance, and Eating Disorder Symptoms in Current and Partially Recovered Anorexia Nervosa Using Structural Equation Modelling

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective Theoretical models and empirical research suggest that identity plays a pivotal role in the development of anorexia nervosa (AN), however, limited research has been conducted on how identity is connected to the expression of eating disorder (ED) symptoms. One possible connecting mechanism is body image disturbance (BID). As such, the
