Investigation of wettability and optical properties of superhydrophobic polystyrene-SiO2 composite surfaces
(Elsevier Science Sa, 2016)
Polystyrene coatings with varying SiO2 nanoparticle contents were prepared by spin coating technique and their wettability and optical properties were investigated. Superhydrophobic surfaces were achieved with water contact ...
Utilisation of Fuzzy Fault Tree Analysis (FFTA) for quantified risk analysis of leakage in abandoned oil and natural-gas wells
(Elsevier Ltd, 2015)
It is a fact that a significant number of drilled wells are abandoned each year. Abandoned wells, those that have been Permanently Abandoned (PA), might have some risks with disastrous consequences. Moreover, abandoned ...
Applicability of Cassie-Baxter equation for superhydrophobic fluoropolymer silica composite films
(Elsevier, 2015)
In this study, surface topographies and wettabilities of flat and composite rough films of perfluoro-styrene (TM/S) random copolymers with silica particles were investigated. The water and oil repellencies of flat TM/S ...
Assessment of thermodynamics performance with sustainable propulsion indicators of a seaplane engine for different temperatures in the same altitude
(Taylor & Francis Inc, 2017)
Seaplanes have become an important tool along with rapidly developing technology in modern transportation for many countries related to sea. Considering the environmental evaluation for these aircraft, decreasing fossil ...
Detection of Nitroaromatic Explosives Based on Fluorescence Quenching of Silafluorene- and Silole-Containing Polymers: A Time-Dependent Density Functional Theory Study
(Amer Chemical Soc, 2014)
Poly(silafluorene-phenylenedivinylene)s and poly((tetraphenyl)-silole- phenylenedivinylene)s are promising materials to be used as chemical sensors for explosives detection. The optoelectronic properties of these polymers ...
Optical and wettability properties of polymers with varying surface energies
(Elsevier Science Bv, 2015)
In this study, flat and transparent thin films of polymers with varying surface free energies were prepared from their solutions to investigate their wettabilities and optical properties. Surface free energies of polymers ...
The effect of pattern sizes on oleophobicity and superhydrophobicity of micropatterned surfaces
(Elsevier Science Sa, 2016)
In this study, cylindrical pillars with varying diameters between 10 mu m to 100 mu m, seperation distances between 5 mu m to 10 mu m, constant heights of 40 mu m +/- 2 and solid area fractions [f(s)(CB) (geo)] between ...
