<p>The field of nanocomposites is gaining considerable attention due to its potential for providing new materials with extraordinary physical properties compared to traditional composite materials. In this thesis cellulose nanowhiskers (CNW) were separated from microcrystalline cellulose (MCC) and dispersed in different biopolymer matrices to obtain polymer nanocomposites based on renewable resources. Moving from microstructure to nanostructure creates new challenges for structure characterization of materials. The overall aim of this work was to characterize the structure of CNW and their nan

Abstract:

Hard gelatin capsules have been used for drug delivery for a long time. The current production process takes advantage of the very unusual properties of gelatin: gelation, very low viscosity, film mechanical properties and film solubility. Although the hard gelatin capsules present many advantages compared to other drug delivery systems, their uses are restricted because of the animal origin of the gelatin. A HPMC gelling agent system is currently used for producing animal product free hard capsules. This work examines the possibility of using a different system in a similar production process

Les constructions en terre crue, soit fabriquées à partir de sol, sont considérées comme des constructions durables en raison de leur faible empreinte environnementale : les matériaux de construction à base de terre crue non stabilisée ont une faible énergie intrinsèque, d'excellentes propriétés hygroscopiques et un fort potentiel de recyclage. Cependant, sous cette forme, les matériaux sont susceptibles de se détériorer au contact de l’eau.

This diploma thesis deals with experimental study of interaction based on polymer-lipid system. The main goal was to investigate interaction leading to phase separation. Three anionic polyelectrolytes were selected for this purpose: sodium hyaluronate, sodium chondroitin-6-sulfate and sodium poly(4-styrenesulfonate). The liposomes were formulated by sonication of lipid – cationic 1,2-dipalmitoyl-3-trimethylamonium-propane (chloride salt) and zwitterionic 1,2-dipalmitoyl-sn-glycero-phosphocholine. It was found that the phase separation occured at specific ratio of DPTAP and selected polymer. It

Nanopores (1 – 10 nm diameter) constructed in solid-state membranes, have shown promise as next-generation biopolymer analysis devices offering both high resolution and high throughput. One promising application of nanopores is in the analysis of nucleic acids, such as DNA. This involves translocation experiments in which DNA is placed in an ionic solution and is forced through a nanopore with the aid of an applied electric field. The modulation of ionic current through the pore during DNA translocation can then be correlated to various properties of the biopolymer such as the length. To opt

The three major mechanical components of cells are the biopolymers actin, microtubules, and intermediate filaments. Cellular processes are all highly reliant on the mechanics of the specific biopolymers and the networks they form, rendering necessary the study of both the kinetics and mechanics of the cytoskeletal components. Here, we study the in vitro mechanics of actin and composite actin/vimentin networks, and the effect of various actin-binding proteins on these networks.<br>Engineering and Applied Sciences

As the world faces resource management problems such as providing sustainable energy and sourcing rare elements, demand is growing for new materials to help combat these. Biopolymer sol-gel synthesis has the potential to create a wide range of functional materials, in particular from the spontaneous foaming of gelatin and metal nitrates upon drying. If this process can be controlled and expanded to other biopolymers then catalytic systems could be designed for many applications. The gelatin foaming mechanism was investigated by a variety of techniques including small angle neutron scattering a

Many biological systems involve intricate, hierarchical networks formed from cross-linked filaments, including the cytoskeleton of eukaryotic cells and the collagen scaffold of the extracellular matrix.

As such, the theoretical and computational modelling of filament assemblies has increasingly utilized discrete fibre network (DFN) models to investigate their complex local and globa

Based on the well-established Wlc theory, I then develop a semi-phenomenological mean-field model of a transiently cross

Abstract:

This thesis examines a system consisting of two biopolymers, gelatine (a protein that forms a gel under certain conditions of temperature and concentration) and dextran (a non-gelling polysaccharide) in solution. At high temperatures the polymers are miscible but at low temperatures (less than 35°C) phase separation and gelation can occur. This thesis investigates this phenomenon using light scattering, microscopy and rheology. It is shown that very different structure are formed depending on the relative rates of phase separation and gelation. At high temperatures the gelation occurs slowly

The use of materials with osteointegrating and bactericidal properties is an important dental strategy. For this purpose, methods for the manufacture of composite material in the form of a film based on hydroxyapatite and natural polymer (alginate) with the addition of inorganic ions and the subsequent saturation of drugs and active substances were developed and investigated. The main theoretical prerequisite for the use of dental implants is the fact of tissue integration with the incorporation of biologically inert materials into the jawbone.
