Biomolecule detection through openings in materials
Nanometer-sized openings, known as nanopores, in materials can electrophoretically drive biopolymers, such as DNA, RNA, and proteins through. The passage, known as translocation, of these biomolecules gives rise to distinct current signals that can be used to detect the length, type, and sequence of the biomolecules. These measurable current signals can be of ionic and/or […]
From order to chaos: Case studies of cellulose and lignin materials
Wood is a natural bio-composite that is composed of primarily cellulose (~40%), hemicellulose (~30%) and lignin (~30%). The former is a partially crystalline polysaccharide composed of glucose units which reinforce the matrix made of hemicellulose and lignin. Although cellulose-derived materials find numerous applications, they must coexist with hydrophobic polymers, which can be challenging due to […]
Multiscale techniques and Machine Learning methods for improving and predicting the properties of nanoporous materials
Metal Organic Frameworks, MOFs, have attracted the last two decades a major interest from scientific community due to their wide range of applications. With the appropriate selection of their primary and secondary building units, one can create structures with tunable properties according to the application they are aimed to be used for, leading to almost […]
Superabsorbent biopolymer matrices from agro-polymers: Rheology, processing, and applications
Superabsorbent polymers (SAP) based on acrylic derivatives exhibit remarkable properties, as they can absorb an impressive amount of water (i.e. from 10 to 1000 times their weight, in g/g). Unfortunately, these polymers are challenged by a poor biodegradability, as well as potential toxicity, and low cost-effectiveness. Consequently, there is a pressing need for alternative materials […]
Modern synthetic approaches fοr bioconjugates and biopolymers aimed at sustainable applications
The development of precisely engineered synthetic biomaterials based on natural biopolymers is a flourishing area of research focusing on establishing high-yielding and facile methodologies to overcome the limitations of the traditional methods of bioconjugation. Along these lines, the development of oxygen-tolerant, controlled radical polymerization approaches enabling the synthesis of a wide variety of hydrophilic, responsive […]
Technologies for the Circular Economy
Technologies for the Circular Economy include materials and process development technologies employing renewable carbon, recycled carbon, and waste carbon (including CO2). The main driver for these technologies is the reduction of greenhouse gas (GHG) emissions and other LCA metrics that will contribute to Procter & Gamble’s stated environmental goals and satisfy consumers’ desire for more […]
Presentation of Group of Physics of Material, Polymer and Disordered system department and materials sciences master in the University of Rouen Normandy
Multiscale Modeling of Complex Molecular Systems
This presentation concerns the in-silico study of complex molecular systems at different levels of description and is divided into two parts. The first one focuses on polymer and polymer-based systems simulated by a mixed particle and field-based Brownian dynamics/kinetic Monte Carlo simulation approach that is fully implemented by the Engine for Mesoscopic Simulations for Polymer […]
Engineering of multiphase soft materials at the microscale
The stability and rheology of multiphase materials like foams, emulsions, and immiscible polymer blends is largely dictated by the characteristics of the involved interfaces and the dynamics of the thin liquid films separating interacting droplets or bubbles. When two bubbles approach each other closely, they typically form a thin liquid film (TLF) between them, which […]
