Mimedi PhD Position

Microfluidic devices for the development of advance therapy medicinal products using acoustofluidic interactions

The aim of this thesis is to develop new microfluidic devices based on acoustofluidic interactions (acoustophoresis) which allows manipulating fluids and particles. These devices will be used to enhance interactions between cells and sort them. The first step of the study will be dedicated to design, including simulation of the device. The second step will concern fabrication (including clean room processes) and experimental validation. At the end, the device will be tested with biologists to validate efficiency in the production of transgenes for new cell therapy and medicinal products.

This thesis will be hosted at the BioMicroDevice Group, Micro-Nano Sciences and Systems (MN2S) Department of the Femto-St institute (www.femto-st.fr) in collaboration with biologist from other MIMEDI project partners.

PhD thesis : Development of a silicon micro-device dedicated to the selective detection of VOCs in indoor air

Context : The quality of the indoor air within buildings is a topic of major importance for public health. Among the numerous chemical compounds that can be found in indoor air, formaldehyde and BTEX (benzene, toluene, ethylbenzene and xylene) are considered as one of the most toxic volatile organic compounds (VOCs).

Objectif : In this context, the goal of this study is to develop and deeply characterize an in-situ micro-device able to identify and quantify these chemical compounds in indoor air. A silicon micro-preconcentrator, a silicon gas chromatographic micro-column and a semiconductor based chemiresistor gas sensor will compose this analytical micro-system.
The main contributions in this thesis concern on one hand the identification and characterization of suitable porous adsorbents allowing the concentration of indoor air pollutants and, on the other hand the synthesis of nano-structured metal oxides (SnO2) using an original deposition technique.
The aim of this PhD is to synthesize and characterize various materials (adsorbents and metal oxide materials) and then to evaluate the detection performances of the micro-device for the identification of indoor air pollutants such as formaldehyde and VOCs.

Candidates’profile : Skills in physical-chemistry, surface science, instrumentation, physical properties of nanostructures, semiconductors and structural characterization techniques.

PhD : Design, modeling, fabrication and characterization of a Stirling micro - engine for energy harvesting and conversion

Context : This project concerns the development of a micro-Stirling enginen for energy harvesting (recovery of lost thermal energy and conversion into electrical energy, and vice versa). It is a collaborative project between the departments MN2S (MOEMSgroup) and ENERGY(THERMIEteam) of theINSTITUT FEMTO-ST–Département MN2S15 B avenue des Montboucons 25030 BESANCON cedex www.femto-st.fr FEMTO-ST institute and which is the result of a committed work with academic partners (University of Savoie and University of Sherbrooke-Canada) on the development of a miniaturized Stirling engine for energy recovery. 

Objective : This phD thesis aims at the realization of a miniaturized Stirling engine by means of clean room technologies (available within the Femto-st institute). In the context of previous projects, some elements of the micro-Stirling engine have already been developed (hybrid membranes, micro-regenerators) [6-9].

Ph.D : Specification and Verification in the Field of Quantum programs

Scientific context : The theory of quantum programming is increasingly studied since the beginning of the 21st century.
Several quantum programming languages have been proposed. Various aspects of quantum computing have been modelized in Haskell, Coq or Isabelle.
This work is in relation with I-QUINS, an I-SITE-BFC project (contract ANR-15-IDEX-03), which brings together theoretical and practical researchers in the field of quantum computing, working together on the building and miniaturization of physical quantum systems.

Candidates Profile and Application : The candidates should have a master degree in computer science, with proved skills in the general area of formal methods, formal specification, verification and validation. Skills in Coq or Isabelle proof environments will be appreciated. Proficiency in English is important, and the candidates shall master writing and presenting scientific work.


Ph.D: Nanotribology of Triboactive Surfaces – Molecularly-assisted Tuning of Friction Laws in a Multi-asperity Tribocontact

Topic: The design and control of materials at the nanoscale are the foundation of many new strategies for energy generation, storage and efficiency. Friction is an important limitation of energy efficiency performances in MEMS/NEMS, whereas it is the primary mean to create energy in new Triboelectric NanoGenerators – ie. nanodevice used for energy harvesting. In this framework, multi-asperity nanotribology studies are needed to develop a fundamental understanding of interfacial phenomena where frictional behavior is controlled by interactions between nano-asperities. The goal of this PhD thesis is to develop new kinds of triboactive surfaces – ie, surfaces in which frictional behavior can be controlled in situ by means of external stimuli – more specifically focused on UV-beam photo-actived monolayers.

Background: Master degree or equivalent degree in physical-chemistry, surface science, or nanophysics

Period: Autumn 2018 – Autumn 2021
