2. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes
Abstract : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. READ MORE

3. Porous Polymeric Monoliths by Less Common Pathways : Preparation and Characterization
Abstract : This thesis focuses on my endeavors to prepare new porous polymeric monoliths that are viable to use as supports in flow-through processes. Polymer monoliths of various porous properties and different chemical properties have been prepared utilizing the thermally induced phase separation (TIPS) phenomenon and step-growth polymerization reactions.

4. Functionalization and processing of porous powders into hierarchically porous monoliths
Abstract : Inorganic porous materials are widely used in a number of applications, where is a need to functionalize and produce materials with a multiscale porosity. The first part of the thesis describes how a novel and facile powder processing approach, using pulsed current processing (PCP) or, as it is commonly called, spark plasma sintering (SPS), has been employed to produce mechanically stable, hierarchically porous bodies from different porous powders.

5. New approaches to preparation of macroporous monoliths for use in liquid chromatography
Abstract : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. READ MORE
