Adsorption of Mercury ... -
Effective UO22+ removal from aqueous solutions using lichen biomass as a natural and low-cost biosorbent
Gul, Ulkuye Dudu; Senol, Zeynep Mine; Gursoy, Nevcihan; Simsek, Selcuk (ELSEVIER SCI LTD, 2019)The UO22+ biosorption properties of a lichen, Evernia prunasui, from aqueous solutions were investigated. The widely occurring lichen samples were collected from the forest in Bilecik-Turkey. The UO22+ biosorption onto ... -
Effects of the Different Methacrylate Monomers on Bond Strength Between Soft Liner and Acrylic Resin
Bolayir, Giray; Soygun, Koray; Simsek, Selcuk; Yilmaz, Ersen; Dogan, Arife; Boztug, Ali; Dogan, Orhan Murat (ASIAN JOURNAL OF CHEMISTRY, 2013)In the present study, tensile bond strength between on acrylic resin and a soft liner, molloplast B, was studied. To enhance the bonding capacity between these materials, acrylic resin surface was modified using ethyl ... -
Investigation of Mechanical and Structural Properties of Blend Lignin-PMMA
Soygun, Koray; Simsek, Selcuk; Yilmaz, Ersen; Bolayir, Giray (HINDAWI PUBLISHING CORPORATION, 2013)This in vitro study investigated the mechanical and structural characteristics of lignin-added PMMA resin composites at concentrations of 1, 3, and 5% by weight. Four sample groups were formed. For the transverse strength ... -
Organoclay modified with lignin as a new adsorbent for removal of Pb2+ and UO2 (2+)
Simsek, Selcuk; Baybas, Demet; Kocyigit, Muzaffer Cagri; Yildirim, Hatice (SPRINGER, 2014)This study investigated a new adsorbent prepared from lignin modified organoclay for the removal of Pb2+ and UO2 (2+) from aqueous solutions. The characterization of new adsorbent was performed by FT-IR and XRD. Adsorption ... -
