1. Functional hybrid and composite porous membranes derived from imidazolium-type poly(ionic liquid)
Abstract : Poly(ionic liquid)s (PIL)s, as a subclass of polyelectrolytes, are composed of polymeric backbones with ionic liquid (IL)-based species in each repeating unit. Recent studies have deepened the understanding of the PIL concept in terms of characteristics, functions and applications in comparison to classical ILs and traditional polyelectrolytes. READ MORE

2. Gas Adsorption and Permeation in MFI Zeolites and Membranes
Abstract : The single and multi component gas adsorption behavior on silicalite-1 and cation exchanged MZSM-5 zeolites (M = H, Na, and Ba) were investigated by a step change response method. Temperature programmed desorption (TPD) and in-situ fourier transform infrared (FTIR) spectroscopy were also performed to study the type of adsorbed species and their thermal stabilities. READ MORE

4. Composite Materials in Molecular Imprinting Technology
Abstract : Molecularly imprinted polymers (MIPs) are artificial plastic materials that mimic antibodies or enzymes. Like natural antibodies or enzymes, molecularly imprinted polymers can selectively bind target molecules or can promote catalytic reactions. READ MORE

5. Modified and hybrid cellulose-based materials for water purification
Abstract : The need for clean water has led to the development of several different water treatment methods as well as to a large number of organic, inorganic, hybrid and/or composite materials that are used in these methods. Cellulose, being a highly abundant biopolymer with meritorious properties, such as high mechanical strength, tunable surface chemistry, high aspect ratio and surface area, to mention a few, is exploited in the current thesis for water treatment applications.
