This PhD project at Université Grenoble Alpes focuses on developing greener and more efficient liquid-liquid extraction processes by investigating anisotropic liquid phases. The research aims to optimize extraction of organic pollutants and metal ions using a system based on decanoic acid and lidocaine, a deep eutectic solvent that avoids strong acids. The project will explore the nanometric organization and rheological properties of these systems, which are crucial for understanding and improving transport and separation processes.

The work will be conducted between two leading laboratories: the Laboratory for Interdisciplinary Physics (LIPhy), specializing in scattering techniques and biphasic systems, and the Laboratory of Rheology and Processes (LRP), with expertise in rheology and out-of-equilibrium X-ray scattering. A two-month secondment at APERAM will provide experience in real industrial extraction conditions. The research is structured into three main axes: (1) equilibrium characterization of the system, (2) microscopic analysis of flow properties using advanced scattering techniques under shear, and (3) investigation of transport phenomena and extraction efficiency under various conditions.

The project is highly interdisciplinary, combining chemical physics, materials science, and engineering, and offers opportunities for advanced training, networking, and international collaboration through the PhD@Tec21 and Marie Skłodowska-Curie COFUND programs. The position offers a 36-month contract with a competitive salary, full social security, health insurance, and support for relocation and administrative matters.

The ideal candidate will have a strong background in physics, chemistry, or chemical engineering, with experience in relevant experimental techniques and a proactive, collaborative approach to research. The application deadline is February 28, 2026, and further details, including eligibility criteria and application procedures, are available on the PhD@Tec21 website.
