Natural gas hydrates from different types and concentrations of surfactant solutions were produced in a high-pressure cell. An anionic, a cationic, and a nonionic surfactant were used to prepare different concentration of surfactant solutions from deionized water. Although the thermodynamics of hydrate formation from a gas mixture is not affected with the existence of surfactants in the environment, there is an appreciable effect of type and concentration of surfactant on hydrate formation rate. The hydrate formation rate is increased with the use of anionic surfactant for all concentrations tested. Hydrate formation rate is also increased at low concentrations of cationic surfactant. The effect of nonionic surfactant is less pronounced compared to anionic and cationic ones.

Facilitation of water management in low Pt loaded PEM fuel cell by creating hydrophobic microporous layer with PTFE, FEP and PDMS polymers: Effect of polymer and carbon amounts ÖZTÜRK, Ayşenur; FIÇICILAR, BERKER; Eroğlu, İnci; BAYRAKÇEKEN YURTCAN, Ayşe (2017-08-17) Microporous layers (MPLs) were prepared with different hydrophobic polymers to establish water management in polymer electrolyte membrane (PEM) fuel cells. Besides conventionally used polymers polytetrafluoroethylene (PTFE) and fluorinated ethylene propylene (FEP), two different molecular weights (MW) of polydimethylsiloxane (PDMS) polymer were used as hydrophobic materials in MPL. Membrane electrode assemblies (MEAs) having MPLs with low MW PDMS polymer exhibited the best fuel cell performance compared to ...
On the dissociation of natural gas hydrates from surfactant solutions Karaaslan, U; Parlaktuna, Mahmut (2001-01-01) Natural gas hydrates from different types and concentrations of surfactant solutions were produced and dissociated in a high-pressure cell. The Clausius-Clapeyron equation was utilized to derive the enthalpy related to the phase transition of the gas component from dissociation data. The results indicated that the phase change enthalpy of the nonionic surfactant solution hydrate is higher compared to that of pure-water and anionic surfactant solution hydrates. Experimental results also show that surfactants...
LANTHANUM DOPED DICALCIUM PHOSPHATE MIXED WITH GRAPHENE OXIDE BONE CEMENTS AS A POTENTIAL MATERIAL IN BIOMEDICAL APPLICATIONS Motameni, Ali; Evis, Zafer; -, -; Department of Engineering Sciences (2021-9-06) In this thesis, mesoporous particles of β-tricalcium phosphate (βTCP, βCa3(PO4)2) and lanthanum (La) doped βTCP were synthesized by wet precipitation method attached with a microwave refluxing system. Pure dicalcium phosphate (DCP) and La modified dicalcium phosphate (La-DCP) bone cements were prepared based on acid/base reaction between βTCP (or La- βTCP) and monocalcium phosphate monohydrate (MCPM) in the presence of water. DCP bone cements were also mixed with 1.5-3.5wt.% of graphene oxide (GO). The obta...
Kinetic studies for boron carbide formation in a dual impinging-jet reactor Noyan-Dilek, S; Ozbelge, HO; Sezgi, Naime Aslı; Dogu, T (2001-02-07) The chemical vapor deposition (CVD) of boron carbide was investigated on a tungsten substrate from a gas mixture of BCl3, H-2, and CH4 in a dual impinging-jet reactor that was connected to an FT-IR spectrometer for on-line analysis of the reactor effluent stream. During CVD of boron carbide, the formation of BHCl2 was experimentally verified, and beta -rhombohedral B4C was formed. Conversion to boron carbide was found to increase with an increase in the BCl3/CH4 ratio. However, conversion to dichloroborane ...
Bacterial application increased the flow rate of CaCO3-clogged emitters of drip irrigation system Eroğlu, Seçkin; Tunc, Talip; Sahin, Fikrettin (Elsevier BV, 2012-05-01) CaCO3 is one of the most common emitter clogging factors among chemical precipitates in drip irrigation systems. Continuous acid application as a classical approach to prevent CaCO3 clogging can be tricky, expensive and hazardous for soil. In order to develop an environmentally friendly method to address the problem, two bacterial strains, one renowned as a PGPR and the other having extensive CaCO3 dissolving capacity, were used in treatments of artificially clogged drip irrigation emitters. Results showed ...
