Design, Synthesis and Characterization of D-glucosamine Low Molecular Weight Gelators
… classes have been found to be excellent organogelators. Carbohydrates are abundant natural resources that are useful in preparing advanced materials. We have previously showed that monosaccharide derivatives can form effective low molecular weight gelators for both organic solvents and …

Synthesis and Characterization of Sugar Derivatives as Functional Gelators
… assemblages of organic molecules known as organogelators and hydrogelators are currently, and only recently, a subject of great attention and promise. In this context, low molecular weight gelators (LMWGs) are of particular interest because they provide a bottom-up approach to the formation …

Synthesis and biological evaluation of aeruginosin based compounds and self-assembly of glucosamine based compounds
… and self–assembly of glucosamine based hydro and organogelators<strong>. </strong>Carbohydrate-based low molecular weight gelators are an interesting class of molecules with many potential applications. A series of amides and ureas were prepared from the protected D-glucosamine from the …

Semicarbazide organogels containing inorganic nanoparticles : new supramer particle hybrid systems
… behaviour of mono- and bis(semicarbazide) organogelators, and the mineralisation behaviour of inorganic nanoparticles in gels formed by these semicarbazide compounds. The amphiphilic structure of these semicarbazide compounds leads to the possibility of formation of hydrogen bonds to …

The Synthesis of Amphiphilic Glycolipids as Potential Inhibitors of Bacterial Adhesion
… glycolipids were tested as low molecular weight organogelators (LWOG), and promising results were obtained. Chapter 3 deals with the synthesis of O- and N-glycolipids built around an aliphatic core. Initially the synthesis proved problematic but success was achieved utilising DMTMM as the …

Influence of Electrostatic and Intermolecular Interactions on the Solution Behavior and Electrospinning of Functional Nanofibers
… and phospholipids surfactants as well as organogelators were studied using solution rheology and DLS to determine the effects of micellar structure and solution viscosity on the electrospinnability of low molar mass surfactants. In addition, the effects of charged and uncharged surfactants …

Organization, manipulation and motion of brush polymers and low molecular weight amphiphiles at interfaces
The aim of this thesis was to study the organization, manipulation and motion of brush polymers on different substrates by means of scanning force microscopy.The main part of this work is concentrated on one specific type of polymer: the monodendron jacketed linear chains. This is a polymer with a …
