Nitro Derivatives of Parabanic Acid as Potential Explosives: A Theoretical Study
Türker, Burhan Lemi; Varis, Serhat (2014-01-01)
This work deals with certain parabanic acid (PA) derivatives because they possess great calculated density (>1.8 gcm(-3)) and high content of nitrogen (26%). Computed ballistic properties of eight different parabanic acid derivatives are presented. The structures were optimized at the B3LYP/6-31G(d, p) level. The calculated data for PA are found to be compatible with the experimental X-ray data. The detonation performance analyses were done using empirical Kamlet-Jacobs equations. Additionally, detonation p...
Nitrite and nitrate removal efficiencies of soil aquifer treatment columns
Güngör, Kerem; Ünlü, Kahraman (2005-05-20)
Bench-scale soil column experiments were performed to examine the effects of soil type and infiltration conditions on the removal efficiencies of wastewater nitrites and nitrates during the biological ripening phase of soil aquifer treatment (SAT) columns. SAT was simulated in three 1-m-high soil columns packed with 3 different natural agricultural soils having sandy clay loam (SCL), loamy sand (LS) and sandy loam (SL) textures. All columns were equipped with tensiometers and soil-water sampling ports, and ...
Isoconversional methods to determine the kinetics of crude oils - thermogravimetry approach
Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2018-08-01)
In this research, kinetics of four crude oils from different origins are determined by iso-conversional methods using thermogravimetry data (TGA-DTG). The experiments were performed at three different heating rates (5-10-15 K/min) between 300 and 1200 K. Thermal characteristics of the crude oil samples such as, reaction intervals and corresponding peak and burn-out temperatures are also determined. Three different iso-conversional methods, known as Starink, Kissinger and Friedman are used in order to determ...

Diametral strength testing of hydroxyapatites doped with yttrium and fluoride
Evis, Zafer; Sun, Z. P. (2010-10-01)
This study aimed to investigate the diametral strength testing of hydroxyapatite (HA) doped with Y and fluoride with different compositions. Hydroxyapatites were synthesised by precipitation method and sintered at 900, 1100 and 1300 degrees C for 1 h. High amounts of doping caused a decrease in relative densities of HAs. Higher sintering temperatures helped in increasing the relative densities. No second phases were observed by X-ray diffraction spectra of 2.5 mol.-%Y and 2.5 mol.-%F doped HA after the sint...
