Hydrogels and organogels are three-dimensional structures with the ability to retain large amounts of liquid in their networks. Hydrogels contain water as the liquid phase whereas organogels structure a nonpolar solvent. Food-grade organogels generally entrap edible oils in their gel matrices. Both gel systems show viscoelastic characteristics and the degree of viscoelastic properties depends on the type and concentration of the used gelators and liquid phases. Biodegradable polymers such as various proteins and polysaccharides are mostly used for hydrogel production. Lipid-based gelators including waxes, fatty acids, fatty alcohols, and lecithin are generally used for the production of organogels. The incorporation of hydrogels and organogels into food systems influences the rheological behaviors and organoleptic properties of such systems. Therefore, rheological characterization of various hydrogel and organogel systems is quite important to achieve food products with desired rheological and textural properties. There is also a growing interest in the combination of hydrogels and organogels to produce bigel systems with distinct rheological properties.

Monovalent cations and their influence on activated sludge floc chemistry, structure, and physical characteristics Kara, F.; Gurakan, G. C.; Sanin, Faika Dilek (Wiley, 2008-06-01) Multivalent cations have been known to be important components of activated sludge floc structure due to their bridging ability of the negatively charged sites on the biopolymer network. Recently in batch systems it was found that excess concentration of monovalent cations led to the deterioration in settleability, dewaterability of sludges and effluent quality of the system. In this study, effect of influent monovalent cations (potassium and sodium) on activated sludge floc structure was investigated in se...
On Micromechanically Based Approaches to Failure in Polymers SCHÄNZEL, Lisa; Dal, Hüsnü; Miehe, Christian (2013-03-22) Rubbery polymers comprise of three‐dimensional network structures, formed by flexible and mobile chains. They exhibit highly non‐linear ground state elastic combined with rate‐dependent inelastic material response. The key challenge in the micromechanically‐based modeling of polymer materials is the construction of micro‐macro transition that provides a bridge between microscopic kinematic variables of a single chain and macroscopic deformation measures of a continuum. The fracture toughness of rubbery poly...
Spherical harmonic-based random fields based on real particle 3D data: Improved numerical algorithm and quantitative comparison to real particles Liu, X.; Garboczi, E. J.; Grigoriu, M.; Lu, Y.; Erdoğan, Sinan Turhan (2011-02-15) The shape of particles often plays an important role in how they are used and in the properties of composite systems in which they are incorporated. When building models of systems that include real particles, it is often of interest to generate new, virtual particles whose 3D shape statistics are based on the 3D shape statistics of a collection of real particles. A previous paper showed mathematically how this can be carried out, but only had a small set of real particle shape data to use and only made a l...
Investigation of cell migration and proliferation in agarose based hydrogels for tissue engineering applications Vardar, Elif; Hasırcı, Nesrin; Hasırcı, Vasıf Nejat; Department of Biomedical Engineering (2010) Hydrogels are three dimensional, insoluble, porous and crosslinked polymer networks. Due to their high water content, they have great resemblance to natural tissues, and therefore, demonstrate high biocompatibility. The porous structure provides an aqueous environment for the cells and also allows influx of nutrients needed for cellular viability. In this study, a natural biodegradable material, agarose (Aga), was used and semi-interpenetrating networks (semi-IPN) were prepared with polymers having differen...
Spectroelectrochemical and Photovoltaic Characterization of a Solution-Processable n-and-p Type Dopable Pyrrole-Bearing Conjugated Polymer Baran, Derya; Balan, Abidin; Esteban, Beatriz-Meana; Neugebauer, Helmut; Sariciftci, Niyazi Serdar; Toppare, Levent Kamil (Wiley, 2010-12-15) D-A-D-type polymers are of high interest in the field of photovoltaics and electrochromism. In this study we report the synthesis and electrochemical properties of PPyBT along with its photophysical properties and photovoltaic performance. PPyBT is soluble in common organic solvents and both n- and p-type dopable, which is a desired property for conjugated polymers. During electrochemistry studies, the onset potentials of the polymer were determined as +0.2V for oxidation and -1.4V for reduction. Using thes...
