Introduction

The IEA “COMPEX” (Towards exotic compositions of transition metal oxides used as positive electrode materials for Li or Na batteries) is developed in partnership between the Institut de Chimie de la Matière Condensée de Bordeaux (ICMCB) UMR-CNRS 5026, Bordeaux, France and the University of New South Wales, Sydney, Australia. It addresses structural changes at atomic scale during recycling of Li or Na batteries.

Missions and research themes

This IEA project focusses mainly on 4d transition metals exotic compositions that have been poorly studied so far. Our study is focused on structural changes occurring during electrochemical intercalation and deintercalation of alkaline ions in Molybdenum (O3-LixMoO2 et O3-NaxMoO2) and Rhodium systems (O3-NaxRhO2 et P2-NaxRhO2).

Introduction

The IEA “NAMICO” (Natural and Mixed Convective mass transfer phenomena impacting solar building envelope performance in urban environment) is developed in partnership between the Centre d’Energétique et de Thermique de Lyon (CETHIL) UMR-CNRS 5008, Lyon, France, the University of New South Wales (School of Mechanical and Manufacturing Engineering) and the University of Sydney. It addresses the comprehension and the mastering of ventilated solar components such as double-skin facades, hybrid Photovoltaic/Thermal collectors, Building integrated solar chimney, … that generate energy.

Missions and research themes

This IEA project focusses mainly on natural convective phenomena generated in open domains. The configuration studied experimentally and numerically is a single channel submitted to homogeneous and inhomogeneous Uniform Wall Flux (UWF) boundary conditions. Moreover, an indoor reduced scale solar chimney experimental test rig coupled to a cubic cavity (modelling a dwelling zone) has been set up in order to focus on the effect of radiation exchanges (wall to wall and fluid medium participating) on natural flow development which is conditioning the energy efficiency of such building integrated solar systems. 

Main OBJECTIVES OF THE PROJECT

The scientific project is focused on flow and heat transfer control, and addresses 3 main subtopics with both experimental and modelling approaches :

  • Laminar-Turbulent transition indicators
  • Impact of the external thermal stratification on a transitional natural convection flow
  • Impact of radiation on the natural convection flow

Introduction

The IRL “FuMa” for Fundamental Mathematics is a joint CNRS – Australian National University (ANU) initiative in the field of basic and applied mathematics, managed by Prof. Filipo Santambrogio (CNRS) and Stephen Roberts (ANU).

Mission and research themes

This project aims at promoting cooperation between mathematicians from every French university, and mathematicians from the Mathematical Science Institute (Australian National University) in Canberra.

The scientific area that we address is very broad, and has been recently extended (the previous version of this project was called AnGe (“ANalysis and GEometry”) in order to include all mathematical sciences with a priority for fundamental mathematics, but allowing projects on applied mathematics to emerge.

The researchers involved in the project have worked so far on various topics, including, in the latest years,

– differential geometry and topology

– representation theory

– harmonic analysis

– partial differential equations and optimal transport

– biostatistics

Support opportunities

The project is endowed with funds from CNRS and ANU, which are used to support research stays of French mathematicians in Canberra or of mathematicians from ANU in France. Longer stays (3 to 6 months) are preferred but one-month visits are also possible. Applications are done by sending a proposal, with a joint research project and a plan for the visit, to the colleagues in charge of the project (see below). The same colleagues should also be contacted for all practical details about the financial support (reimbursement, bookings, eligible expenses, amount…), which usually covers flight tickets, accommodation, and a small per-diem for local expenses. For French “enseignant-chercheurs” wishing to organize a 6 months visit to ANU the project can also support a request for a CNRS “délégation”.

Introduction

The IRP “REDOCHROME” focusing on redox-active and multipolar organometallic assemblies for photonics and molecular electronics is a joint CNRS-ANU and UWA initiative in chemistry. It focuses on molecular photonics and electronics and involves 24 Australian and French researchers. It is the continuation of a Franco-Australian PICS project initiated in 2015 between French researchers at the Institute of Chemical Sciences of Rennes (ISCR), a joint CNRS-University of Rennes 1 unit (UMR CNRS6226), and Australian researchers at ANU.

Missions and research themes

The main research theme concerns the chemical synthesis of redox-active carbon-rich organometallics and related molecular-based materials. These discrete molecular assemblies are often endowed with remarkable electronic and optical properties. Such assemblies are amongst the most complex systems at the nanoscopic scale and are challenging to model theoretically, a situation which calls for more experimental insight into these paradigmatic molecules. The Redochrom LIA involves French researchers from Rennes (UR1) and Toulouse (UPS) universities and Australian partners located at two top-ranking universities, namely the Australian National University (ANU) in Canberra and the University of Western Australia (UWA) in Perth. This group of French and Australian organic and organometallic chemists has additional expertise in spectroscopy, linear and nonlinear optics (LO and NLO) and electron-transfer, and unique instrumentation. The purpose of this LIA is to develop an understanding of these fascinating architectures, so as to permit their use as discrete molecular-based devices in various applications related to photonics and electronics.

MAIN OBJECTIVES OF THE PROJECT

In a continuation of ongoing collaborative projects that link the French and Australian team members, one part of the project is aimed at establishing reliable structure-property relationships for designing (electro-)switchable two-photon absorbers based on redox-active organometallics, which constitute a little-explored class of compounds from the standpoint of their NLO properties. Such materials have potential applied outcomes in all-optical information treatment and other societal uses. A key focus of the Redochrom consortium is to elucidate the role of the metal center(s) on these optical properties.

The second part of the project will progress molecular electronics research beyond two-terminal metal/molecule/metal junctions, based on linearly conjugated organic molecules.

Chemical synthesis, electro- and photo-chemistry and quantum chemical calculations will be deployed to develop understanding of molecular electronic structure as a function of redox state. This highly collaborative research program will create structures in which molecular electronic properties directly impact on the room temperature operating characteristics of the device. By providing both tools and chemical concepts that address the issues of molecule-surface interactions, charge transport across these interfaces, and function, we will advance the field of molecular electronics, increase the critical mass of activity in the area, and improve bilateral research capacity. Furthermore, the synergy between these two complementary facets (molecular photonics and electronics) will facilitate study of each topic in greater detail than in a project concerned with only one of these areas. This synergy is expected to foster more rapid strides towards realization of practical devices made from carbon-rich organometallics.

France

  • Frederic Paul (DR CNRS, PI), UMR CNRS 6226 (ISCR-COrInt Team)
  • Jean-François Halet (DR CNRS, co-PI), UMR CNRS 6226 (ISCR- CTI Team)

The consortium of French researchers at Institut des Sciences Chimiques de Rennes (ISCR).led by F. Paul and J.-F. Halet belongs to different groups and teams at ISCR. Besides the strong organic or organometallic chemical synthesis component which is shared by most French participants of ISCR (iron alkynyl complexes; porphyrins; organic chromophores and fluorophores), some team members bring more specific expertise in various physico-chemical fields (silicon surface functionalization and electrochemistry, mixed-valent compounds, second-order and third-order NLO studies). The latter are complemented by ultrafast transient absorption spectroscopic facilities at the Institute of Physics of Rennes (M. Lorenc, IPR). There is also a strong computational component present among the French delegates (led by J.-F. Halet and A. Boucekkine at ISCR), complemented by a specialist in excited-state calculations in Toulouse (I. Dixon, LCPQ-UPS).
