Photodimerizations of hydroxy- and benzoylated 4-azachalcones and quantum chemical investigation of the reactions
(2010)Photodimerization reactions of compounds 4-6 gave four new cyclobutane-containing compounds (7-9) with full control over the stereochemistry at the four stereogenic centers. These new cyclobutane- containing compounds had ... -
Complexation of metal ions with double-armed diazadithia lariat ether carrying anthracene moieties in acetonitrile-dioxane
(2010)A new 14-membered crown ether with nitrogen-sulfur donor atom carrying two anthryl groups was designed and synthesized by the reaction of the corresponding macrocyclic compound and 9-(chloromethyl) anthracene. The influence ... -
The effect of PowerPoint presentations prepared and presented by prospective teachers on biology achievement and attitudes toward biology
(2010)The study aims to explore the effect of preparing and presenting powerpoint slides on prospective teachers' biology achievement and attitudes toward biology. The sample of the study was 109 freshman students from Pre-School ... -
Thermodynamics and kinetic studies of biosorption of a basic dye from aqueous solution using green algae Ulothrix sp.
(2010)This study addresses removal of a basic dye, methylene blue, from aqueous solutions by using dried Ulothrix sp. biomass as biosorbent. The effects of the initial dye concentration, contact time, temperature, solution ... -
Energy production, consumption, policies and recent developments in Turkey
(2010)Many factors to be appropriately addressed in moving towards energy sustainability in Turkey are examined. These include harnessing sustainable energy sources, utilizing sustainable energy carriers, increasing efficiency, ... -
Characterization of liquefaction susceptibility of sands by means of extreme void ratios and/or void ratio range
(American Society of Civil Engineers (ASCE), 2010)The liquefaction susceptibility of various graded fine to medium saturated sands are evaluated by stress controlled cyclic triaxial laboratory tests. Cyclic triaxial tests are performed on reconstituted specimens having ... -
Complexation of metal ions with the novel diazadithia crown ethers carrying two pyrene pendants in acetonitrile-tetrahydrofuran
(2010)Two crown ethers carrying pyrene side arms with nitrogen-sulfur donor atom were designed and synthesized by the reaction of the corresponding macrocyclic compounds and 1-bromomethyl-pyrene. The influence of metal cations ... -
Complexation of metal ions with the novel diazadithia crown ether carrying two anthryl pendants in acetonitrile-tetrahydrofuran
(2010)A new crown ether carrying two anthryl groups with nitrogen-sulfur donor atom was designed and synthesized by the reaction of the corresponding macrocyclic compound and 9-chloromethyl anthracene. The influence of metal ... -
Improvements on slope diffraction for multiple wedges
(2010)This article proposes an improved slope uniform theory of diffraction model for fast and more accurate field prediction for multiple wedge diffractions in the transition zone. The proposed method is based on the slope ... -
The first occurrence of the mite family linotetranidae (Acari: Tetranychoidea) in Turkey: Linotetranus anatolicus n. sp
(2010)A new species Linotetranus anatolicus Doan and Donel, n. sp. collected from soil, litter, oak bark and moss is herein described and figured. This is the first time that the family Linotetranidae has been recorded from ... -
Synthesis of two alnustone-like natural diarylheptanoids via 4+3 strategy
(2009)The first total synthesis of (4E,6E)-1,7-bis(3,4-dihydroxyphenyl)-hepta-4, 6-dien-3-one and an alternative synthesis of (4E,6E)-1,7-bis(4-hydroxyphenyl)- hepta-4,6-dien-3-one, two natural diarylheptanoids, mainly based on ... -
The role of cobalt doping on the optical and structural properties of Mn 3 O 4 nanostructured thin films obtained by SILAR technique
(Academic Press, 2019)Cobalt doped manganese oxide thin films (Mn 3 O 4 :Co) were successfully deposited on soda lime glass substrates using SILAR technique. Mn 3 O 4 :Co thin films were characterized using XRD, SEM, Uv–VIS and Raman spectroscopy. ...
