Analytical solution of Poisson-Boltzmann equation for interacting plates of arbitrary potentials and same sign
Polat, Mehmet; Polat, Hürriyet (Elsevier, 2010-01)Efficient calculation of electrostatic interactions in colloidal systems is becoming more important with the advent of such probing techniques as atomic force microscopy. Such practice requires solving the nonlinear ... -
Ancillary effects of surfactants on filtration of low molecular weight contaminants through cellulose nitrate membrane filters
Olcay, Aybike Nil; Polat, Mehmet; Polat, Hürriyet (Elsevier, 2016-03-05)Removal of contaminants with low molecular weight (<800 Dalton) requires the use of advanced separation techniques such as ultrafiltration (UF) or micellar enhanced ultrafiltration (MEUF). However, surface active agents ... -
Capacity and mechanism of phenol adsorption on lignite
Polat, Hürriyet; Molva, Murat; Polat, Mehmet (Elsevier, 2006-07)A raw lignitic coal from Soma, Turkey was investigated to determine its potential as an adsorbent for phenol removal from wastewaters. Kinetic batch tests demonstrated that phenol could be completely removed from solution ... -
Designing of spherical chitosan nano-shells with micellar cores for solvation and safeguarded delivery of strongly lipophilic drugs
Cihan, Esra; Polat, Mehmet; Polat, Hürriyet (Elsevier, 2017-09)Chitosan is a very effective biopolymer for drug delivery purposes due to its biocompatibility, positive charge and exceptionally pH sensitive degradability behavior in an aqueous medium. Nevertheless, its inability for ... -
Determination of the particle interactions, rheology and the surface roughness relationship for dental restorative ceramics
Kes, Mürşide; Polat, Hürriyet; Keleşoğlu, Serkan; Polat, Mehmet; Aksoy, Gökhan (Elsevier, 2009-11)The effect of inter-particle interactions on the slurry properties and the final surface roughness of the dental ceramic restoratives was investigated. A commercial dental ceramic powder, IPS Empress 2 veneer, was used as ... -
Effect of various treatment and glazing (coating) techniques on the roughness and wettability of ceramic dental restorative surfaces
Aksoy, Gökhan; Polat, Hürriyet; Polat, Mehmet; Çoşkun, G. (Elsevier, 2006-12)Surface treatment procedures such as grinding and polishing are needed to provide the ceramic dental restorative materials with proper fitting and occlusion. The treated surfaces are customarily glazed to improve the ... -
Encapsulating fly ash and acidic process waste water in brick structure
Köseoğlu, K.; Polat, Mehmet; Polat, Hürriyet (Elsevier, 2010-04)Fly ash contains metals such as cadmium, iron, lead, aluminum and zinc in its structure in appreciable amounts. These metals can leach out into surface and ground waters if fly ash is not properly disposed of. A similar ... -
Kinetics of oil dispersion in the absence and presence of block copolymers
Polat, Hürriyet; Polat, Mehmet; Chander, Subhash (American Institute of Chemical Engineers, 1999-09)A phenomenological model proposed describes droplet breakup in the turbitlently agitated lean oil-in-water dispersions and provides a correlation between the median droplet size in an agitated vessel of standard geometry ... -
A new methodology for removal of boron from water by coal and fly ash
Polat, Hürriyet; Vengosh, Avner; Pankratov, Irena; Polat, Mehmet (Elsevier, 2004-04)High levels of boron concentrations in water present a serious problem for domestic and agriculture utilizations. The recent EU drinking water directive defines an upper limit of 1 mgB/I. In addition, most crops are sensitive ... -
Physical and chemical interactions in coal flotation
Polat, Mehmet; Polat, Hürriyet; Chander, Subhash (Elsevier, 2003-09)Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent ...
