The main adsorption mechanisms using zeolite and magnetite nanomaterials are high surface adsorption, ion exchange capacity and electrostatic interaction.

Philosophical health and wuxing ontology.

Introduction: In recent years, a new form of health has emerged, namely philosophical health. This novel concept is part of the philosophical counseling movement and relies on the philosophical method called the SMILE-PH interview, which draws heavily from continental philosophy, including phenomenology. Reflecting on the link between health and philosophy brings us to an ancient healthcare tradition that actively relies on philosophy: Chinese healthcare and its founding wuxing, or five phases ontology.
