Nanomaterials processing for medical, cosmetic, and environmental applications

In this research unit, we would like to propose new processes for wastewater treatment and functional materials production with environmentally benign and economically feasible manners.

1- Oxidation process for wastewater treatment (g. wet air oxidation, hydrothermal catalytic treatment, pulsed discharge). We aim to develop and establish an efficient and feasible method for the quick degradation of harmful organic components in wastewater. Nitrogen-containing and sulfur-containing organic components are starting materials.

2- Biomass treatment to value-added chemicals and functional materials (e.g. saccharification, oligopeptide/amino acids production, liquefaction, solid waste for adsorption).  We aim to investigate reaction behavior of various kinds of lignocellulosic biomass and marine biomass in subcritical and supercritical water to find out conditions where high yield of saccharides and amino acids can be obtained. As for residues, we also aim to establish the way how to prepare solid acid catalyst, solid adsorbent for odor, organic acids, sulfur-containing undesired volatile components.

3-  Advanced extraction processes for medical, pharmaceutical, and agricultural fields (e.g. shock waves, ultrasounds pretreatment, microwave, supercritical CO2, subcritical water).  We aim to develop an efficient and feasible method for extracting value-added and bioactive components with supercritical CO2 with or without pretreatment such as shockwave, microwave irradiation, pulsed discharge, etc.). We also aim to achieve micronization of the extracts to produce new products applicable to foods, pharmaceuticals, medicine, etc.

4- Nanomaterials production processes for medical and industrial fields (e.g. pulsed discharge, supercritical fluids).  We aim to develop and establish an efficient, effective, and feasible method for the synthesis of nanomaterials where tuning of their characteristics will be possible by changing the initial parameters of the method. Furthermore, we intent to apply the synthesized materials in the industrial and biomedical fields.
