PhD topic
MICRO AND NANOMETRIC CONTRAST AGENTS
FOR MULTIMODAL MEDICAL IMAGING AND THERAPY
The proposed PhD study deals with contrast agents (CA), which consist in small particles
used to enhance contrast of medical images in ultrasonic (UI) and magnetic resonance
imaging (MRI). Recently, therapeutic applications of CAs, such as localized drug delivery,
gene therapy and sonoporation - have been investigated. The objective of this PhD is to allow
for an improved control of their therapeutic effects through a better understanding of their
physics. The research work includes 3 steps:
1. Fabrication of multimodal (UI/MRI) contrast agents made of magnetic
nanoparticles attached to micro-bubbles.
2. Magnetic and ultrasonic characterization of these contrast agents.
3. Modeling of their interaction with ultrasonic and magnetic fields.

Sujet de thèse : Study and development of the nanopowders for sustainable energy and
environment. Application: Optimization of the catalytic materials for the conversion of syngas to
ultraclean hydrocarbon fuels.
Nanoparticles have very interesting properties like lower size, high surface area, fast
dissolution, exceptional covering capacity and high activity. Because of this potential, the
nanoparticles find use in variety of different areas such as electronic, magnetic,
pharmaceutical, painting, cosmetic, catalytic and energy applications. This encourage
increase in the production on nanopowders by 100% these last years and one speaks about
a phenomenal development, passing to a market of several billion dollars by 2020.
The nanoparticles mainly utilized in the sectors of catalytic chemistry and nanomaterials.
These two sectors together cover almost 44% of the current market.
This huge increase in manufacture and use of nanoparticles makes it likely increasing human
and environment exposure to nanoparticles.
However, the system of the nanopowders is complex, distinctly different from its bulk
counterpart and needs most powerful analytical techniques to study its properties. Despite of
this nanoparticles recently form the basis for any catalysts and electrocatalysts of great
importance to future energy and fuel technologies.
This thesis is related to the study of nanomaterials intended for the heterogeneous catalysis
for the production of the ultraclean hydrocarbon fuels.
In this work the nanometric powders will be developed for the use of the industrial products
and insisting on the approach of safety and environment (toxicology and epidemiology).
The program of this thesis is structured around the following objectives:


Contexte Scientifique
Hydrogen is widely regarded as a promising future energy source to address a series of
crisis of the oil shortage, climate change and environmental pollution, which derive from the
exploitation and utilization of fossil fuels.1, 2 Hydrogen energy is crucial to any clean energy
policy based on its high-energy capacity and environmentally friendliness. Moreover, the
widespread application of fuel cells becomes closer to reality so increased attention is focused
on hydrogen production technologies. As a matter of fact, there has arisen a strong interest in
using H2-based fuel cells as future source of energy due to the high conversion efficiency of
hydrogen energy to electricity as well as the absence of pollutant gases emission. Globally,
the Steam Reforming (SR) of natural gas, especially methane, is still the most commonly used
and the most economically competitive method for H2 production. In order to support clean
and sustainable hydrogen economy, it is urgently desirable to produce hydrogen from
renewable energy sources, such as biomass or biomass-derived materials.3 The current mature
biomass-fermentation technology makes bio-ethanol a highly available and low-cost
feedstock for H2 production.4 Ethanol is easily transportable, safe to handle and store, nontoxic liquid fuel that can be used everywhere since mishaps do not lead to significant

environmental damage, as is the case with oil. Ethanol is already a major fuel in Brazil and in
USA and is making its way to Europe.
The Steam Reforming of Ethanol (SRE) reaction is not thermodynamically favorable
at low temperatures, and essentially requires an extra energy input. Such high temperature
operations (≥ 650 °C) not only consume plenty of energy, but also bring inconvenience to the
application of hydrogen to fuel cells. On the other hand, the energy needed can be supplied by
adding some O2 or air into the feed. This idea enables the exothermic Partial Oxidation of
Ethanol (POE) to thermodynamically take place at low temperatures, during which a portion
of ethanol is burned to offer the required energy so as to simultaneously achieve the SRE
reaction. In such a context, a technology combined with the SRE and POE processes,
generally called the Autothermal Reforming of Ethanol (ATRE), would be promising for the
on board H2 production, that is, for the mobile applications that call for high hydrogen
selectivity and rapid response. The autothermal reformer must be adiabatic, which is
important for the control of energy.
The catalytic transformation of different alcohols has already been studied in our laboratory
(Unité de Catalyse et de Chimie du Solide – UMR CNRS 8181). As hydrogen production
from renewable sources such as biomass is gaining attention at the international level, and
taking into account the already very good results obtained in the laboratory,5,6 especially at
low temperature, we wish to pursue the studies on hydrogen production by transformation of
ethanol. This work requires to prepare catalysts and to analyze their catalytic performance in
transformation of ethanol in a fixed-bed reactor. Besides, physico-chemical characterizations
will be necessary for understanding the different phenomena involved in order to be able to
optimize the catalytic formulation (X-Ray Diffraction, XPS, Raman, IR, UV, TPR,
Microscopy …). Moreover, an autothermal reactor will be also developed in order to optimize
the management of the energy.

Background, Context:
Smart materials consisting of elastomer composite are opening up a realm of opportunities for
the development of portable and flexible devices, in particular, materials whose mechanical
properties are coupled to external stimuli such as temperature (shape memory elastomer or
polymer), electric field (piezoelectric materials) and magnetic field (elastomer composite based
on nano-particles). These flexible materials have attracted a great deal of interest in various
applications ranging from medical (artificial muscles, surgical tools, sensors networks,...),
biomimetic robots, autofocus lens positioning, tactile displays and sensors, reconfigurable RFMEMS, and active fluid pumps. Flexible, high performance at low driving power, easily
processed, robustness and lightweight construction are key requirements, for both applications.
To meet these needs, various solutions of smart polymeric materials, such as dielectric, ionic,
piezoelectric, and magnetic polymers are currently under investigation (1, 2). From a
technological point of view, these materials are of interest for many uses, but they suffer from a
lack of performances: for example high driving voltage for dielectric polymers, low switching
time for ionic polymers, low force for piezoelectric polymers, and hard integration for driving
elements in the case of magnetic polymers. Therefore, the development of advanced materials
which present an exalted response when they are submitted to external stimuli will be critical to
progress in this areas. The recent advances in synthesis and assembling of nano-materials
(graphene, carbon nanotubes CNT, carbon nano-fiber CNF, colloidal magnetic nano-particles,
piezoelectric nano-crystals...) with exalted mechanical, electro-chemical, piezo-resistive,
piezoelectric, magnetic and other physical properties has opened the possibility for the
development of a new class of smart nano-materials. The addition of these nano-materials
within flexible elastomers enables new means to elaborate elastomer composites with exalted
response to an external stimuli. Additionally, the emerging techniques in nano-fabrication have
the potential to optimize these elastomer composites responses, expand the range of device
structures that can be considered and simplify processing.
The proposed thesis deals with the development of new smart elastomer composites (including
magnetic, piezoelectric and ionic elastomers) based on active nano-materials such as magnetic
nano-particles (Fe, Fe3O4), piezoelectric nano-crystals (LiNBO3, KNBO3,PVDF), or
graphene, CNT, CNF. The related structural, physical properties, and the interfacial interactions
of elastomers chains with the surfaces of dispersed nano-materials will be investigated. These
are critical for understanding and improving the electro-mechanical coupling of these elastomer
nano-composites. The main aim of this thesis is to propose new smart elastomer materials to
advance the performance of existing solutions by thoroughly understanding the role of smart
nano-materials in the composite. In terms of functional flexible devices, we focus especially on
the development of low-power, fast time response, high sensitive transduction mechanism
capable of sub/millimeter scale displacement depending on the targeted application. In our
case, examples of targeted applications are elaboration of compact and portable flexible tactile
display surface for augmented reality (3), or artificial skins that mimic the characteristics of
natural dermal tissues for potential use in robotics, or for RF reconfigurable antenna with
operation frequency around of 60GHz (4).

The limits of CMOS technologies will soon be reached and the tremendous energy dissipation
of the current concepts hinders the continuous performance increase of our information
processing systems. In the same time, the energetic footprint on the environment becomes
significant. It is thus compulsory to find new paradigms for the processing and storage of
information to meet our ever-growing needs and reduce the impact on the environment. Brain
inspired ‘neuro-morphic’ architectures are a promising lead for a large processing capability
with a high efficiency. The two laboratories IEMN (hardware side) and LIFL (software side)
recently started to collaborate to explore these bio-inspired architectures and develop the
required components for their implementation. Current models and simulations involve
artificial neuron networks that are interconnected with synapses that exhibit plasticity and thus
present learning capabilities. Such a network requires an artificial synapse that is not readily
available so far.
To implement such a synapse, our proposal is to develop a memristor component based on
artificial multiferroic nanostructures, which are a specialty of our International Associated
laboratory – LIA LICS/LEMAC at IEMN. In order to induce the memory/plasticity, hysteretic
phenomena of the magnetic and/or electric systems will be taken advantage of. The devices
will first be explored using the available theoretical and numerical means at IEMN. A model
that can be integrated in neural networks simulation tools of LIFL will be proposed so as to test
the expected performances and perform a feedback on the device conception. The objective of
the doctoral work is the realization of a crossbar prototype with 256x256 connections showing
effective learning capabilities with a possible applications to image processing or artificial
vision.
Profil du candidat
This doctoral work involves both theoretical and prototype fabrication in the clean room
facilities of IEMN. Preferably, the candidate will have a Master’s degree with a physics,
electronics or micro/nano systems major. Interest for magnetic and ferroelectric thin films is a
plus as well as knowledge in clean room environment and spintronics. The candidate will have
to be fairly autonomous. The research field being relatively recent and hot, the doctoral
candidate will be free to express his (her) creativity.

Coordination du réglage primaire de fréquence de générateurs dispersés à base

Bruno FRANCOIS
Lieu de la Thèse : Ecole Centrale de Lille
Equipe de Recherche du laboratoire de recherche : Ecole Centrale de lille
Les générateurs à base d’énergie renouvelable sont
raccordés au réseau électrique par des
convertisseurs électroniques de puissance. Pour
permettre le développement massif de ce type de
production, ces convertisseurs vont devoir
participer à la gestion du réseau électrique comme
les moyens classiques de production d’électricité
(alternateurs). Pour faire cela, la fonction réglage
primaire de fréquence est synthétisée sous forme
d’algorithme de commande et implanté dans le
système de contrôle de l’onduleur. De par leur
faible puissance, ces générateurs sont raccordés sur
le réseau de distribution électrique ce qui conduit à
constituer localement de la réserve de puissance.
Cependant, la multiplicité de ce type de
générateurs participant au réglage de fréquence
avec des paramètres de réglage différents et aussi
des puissances générées variables peut conduire à
une dégradation de la disponibilité de la réserve
primaire de puissance et à une instabilité du réseau
électrique. De plus, certains générateurs peuvent être beaucoup plus sollicités pour réaliser ce
réglage de fréquence que d’autres, ce qui va à l’encontre de l’équité des acteurs du système
électrique dans un marché libéralisé de l’électricité.
Le sujet de cette thèse aura pour but d’étudier l’effet des paramètres de réglage de contrôleur
primaire de fréquence sur la stabilité d’un réseau électrique de distribution par une étude
théorique. La disponibilité de la réserve primaire selon qu’elle soit issue de l’énergie
renouvelable variable pour les générateurs ou issue d’énergie stockée (stockage distribué sous
forme de batteries) sera évaluée. En effet, la variabilité de la production rend plus difficile la
caractérisation de la contribution des fermes éoliennes. Avant d’exiger leur participation, il
convient donc de réfléchir aux solutions techniques permettant de gérer cette intermittence.
Ensuite, les technologies des réseaux électriques intelligents et notamment les réseaux de
communications seront exploités afin de déployer une stratégie de coordination de ces
générateur au réglage de fréquence en mettant en œuvre une technique permettant l’adaptation
à distance des paramètres de réglage des correcteurs.

PhD Title: Dynamic itinerary optimization inside hypermarkets
Supervisor: Prof. Abdelkader EL KAMEL
Location : Ecole Centrale de Lille
Research Team & Lab: COSy "Control and Optimization of complex Systems" du LAGIS
Institution or Industrial Partner: First part of this work was carried out in cooperation
between industrial partner LEROY MERLIN and the Region Nord in the frame of Mrs. HADJ
KHALIFA PhD Thesis defended on June, 2010. A possible pursuing partnership is considered
and under investigation.
Scientific Context: Shopping in supermarkets is a burden for some people since spending hours looking for
items seems to be tiring and boring especially if it is the first visit. After the electronic commerce (e-commerce),
the mobile commerce (m-commerce) represents, nowadays, a new channel in distribution. Indeed, mobile
applications give to the companies the possibility to be present on the customer’s everyday life. Thanks to the
new technologies such as Bluetooth, the Wi-Fi, the NFC (Near Field Communication), and the QR Code (Quick
Response Code), we find the ubiquitous commerce (u-commerce).
This research is a part of a project which aims to design an intelligent indoor navigation system dedicated to
guide customers during their shopping inside hypermarkets to show them, in real time, the route to pick up their
items. In previous work (Hadj Khalifa, 2010a), we presented the architecture of i-GUIDE system. We chose the
RFID technology (Radio Frequency IDentification) coupled with the Wi-Fi installed in the hypermarket to locate
the customer in the hypermarket. Furthermore, we need an optimization algorithm to compute the shortest path
visiting all items once. In (Hadj Khalifa, 2010b), we proposed a methodology to determinate distances between
each two items in the hypermarket. Thus, when the user enters his shopping list, the system determines his
position, thanks to RFID tags, and locates the items from the database and then the shortest path is computed.
After that, the application guides him along the way by giving him directions. When the RFID tags indicates that
the user takes a different direction, the system prompts the user to add the desired item and the corresponding
shortest path is dynamically recomputed (Hadj Khalifa 2010a). Furthermore, we proposed an Android mobile
application to facilitate the use of the system (Hadj Khalifa 2011). We chose the Android operating system
because it is an open source and it becomes the leader of the worldwide Smartphone market. The Android
application needs a calculator to compute the shortest itinerary in a reasonable computing time.
Candidate profile: Good level, dynamic & motivated candidates with strong background on
Optimization Techniques, Logistics/OR, Programming & Simulation. Particular skills on
Modeling (UML, BPMN…) and Technological/Eng. Implementation are appreciated.
