(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 ...
