Abstract:

Genetic polymers (DNA, RNA and analogues) and molecular programming techniques open unprecedented opportunities for the creation of molecular-scale information systems. For example, reaction networks with arbitrary topologies, build form synthetic DNA oligonucleotides can display rich non-linear behaviour. We can therefore reproduce in test tubes the fundamental dynamical systems underlying cell-scale computation, like oscillators, bistable switches, etc. In addition, molecular circuits open the route to a number of technological applications. Artificial molecular circuits can be combined with high throughput microfluidics techniques to implement highly parallel signal processing tasks in moleculo. I will discuss in particular a stochastic molecular optimisation technique addressing the challenge of protein design, as well as diagnostic applications.

Biographie:

Yannick Rondelez est actuellement chercheur au CNRS au laboratoire Gulliver (UMR 7083), à l’ESPCI. Après une formation académique en Physico Chimie à l’Ecole Normale supérieure de Cachan, il fait une thèse sur les modèles synthétiques de métallo-enzymes avant de partir au Japon pour un post-doc centré sur la biophysique (étude des protéines-moteurs). De retour en France, il travaille dans le consulting (créativité et heuristique) avant d’être embauché au CNRS, d’abord au Japon (LIMMS). En 2016, il déménage son groupe à l’ESPCI et développe un projet de recherche sur l’information au niveau moléculaire et la manière dont on peut rationnellement assembler des composants chimiques simples pour obtenir des systèmes dynamiques complexes.

Abstract :

Transmission Electron Microscopy (TEM) is widely used to study the properties of the matter at the highest spatial resolution. There is a wide literature that reports on the study of single nanoparticles of inorganic material showing how fundamental subtle physical effects can be understood by TEM experiments. High Resolution TEM (HRTEM) enables to directly access the structural properties of individual particles correlating the structure, the crystal perfection, or the presence of defects, to the their behavior enabling the development of new powerful materials for a huge variety of applications. The study of single particles enables to distinguish in a batch of nanoparticles the differences between them and the relevant influence on macroscopic behavior of the material. In the case of radiation sensitive material, like biologic material or nano-crystalline salt drugs, standard HRTEM approaches on single particles could fail due to the damage induced by the high-energy electrons on the specimen. Here will be shown how HRTEM imaging on pristine radiation sensitive single nano clusters can indeed be obtained, enabling to directly image the crystalline properties of soft matter and biologic nanoparticles that was believed not possible to study by atomic resolution TEM.

ABSTRACT: 
Since its launch in 2002, Nature Materials remains a leading journal in the field of materials science across many disciplines, aiming at publishing cutting edge science for the relevant scientific communities as well as disseminating exciting results among the wider readership of materials scientists. This talk will describe how these principles shape the editorial process in Nature Materials and other journals within the Nature family, amidst a rapidly changing scientific publishing landscape, underlining the key points from submission of original research papers to publication.

About Maria Maragkou:

Maria joined Nature Materials in January 2015, after briefly working in Nature Photonics. She has a first degree in electrical and computer engineering from the University of Patras, Greece, and a PhD in physics from the University of Southampton, UK on the topic of light-matter interactions in semiconductor microcavities. She then worked as a postdoctoral researcher at the Universidad Autónoma de Madrid, Spain and at the École Normale Superiéure in Paris, studying quantum optics with epitaxial quantum dots.
