Iteration method for simultaneous estimation of vertical profiles of air temperature and water vapor with the high spectral resolution of sounder of AQUA/AIRS data is proposed. Through a sensitivity analysis based on the proposed method for the several atmospheric models simulated by MODTRAN, it is found that the proposed method is superior to the conventional method by 41.4% for air temperatur...

   In this research, the classical phase inversion method was used to produce the polysulfone (PSF) membrane by using three different solvents: N, N-dimethylformamide (DMF), chloroform (CHCL3) and tetrahydrofuran (THF). Furthermore, different concentrations of functionalized multi – walled carbon nanotubes (MWCNTs) were added to PSF membranes by the classical phase inversion method...

Nanoemulsions are kinetically stable liquid-in-liquid dispersions with droplet sizes on the order of 100 nm. Their small size leads to useful properties such as high surface area per unit volume, robust stability, optically transparent appearance, and tunable rheology. Nanoemulsions are finding application in diverse areas such as drug delivery, food, cosmetics, pharmaceuticals, and material sy...

Background and Objectives: Different types of instability occur at sea. Layered structures are one of the most important physical phenomena in marine environments. Static stability and double diffusion are associated with density changes with respect to depth and temperature and salinity gradients, respectively. Due to the difference in temperature and salinity in the water column, marine areas...

in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...

In conventional chemical Enhanced Oil Recovery (EOR), surfactant mixtures must be optimized to obtain the so-called “optimum formulation” characterized by a three-phase behaviour (WIII) and an ultra-low interfacial tension between crude oil injected water. To attain this condition, discontinuous salinity scans of Surfactant-Oil-Water (SOW) systems are usually performed in series sealed pipettes...
