Catalytic activities of Pt thin films electrodeposited onto Bi coated glassy carbon substrate toward formic acid electrooxidation
(Elsevier, 2014)
Formic acid oxidation was studied on platinum-coated bismuth deposits on glassy carbon substrate. The catalyst was prepared by a two-step process using chronocoulometry, i.e. controlled amount of Bi was electrodeposited ...
Nanoplasmonic chemical sensors
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
This work considers nanoplasmonic structures applicable in chemical and biological sensing. It offers a possible classification of these structures and an overview of the state-of-the-art sensing schemes that utilize them. ...
New Pseudoguaiane Derivatives from Inula aschersoniana Janka var. aschersoniana
(Natural Products Inc, Westerville, 2014)
The aerial parts of Inula aschersoniana Janka var. aschersoniana afforded parthenolide, diepoxycostunolide, inusoniolide, chrysosplenol C and four new pseudoguaiane-type sesquiterpenoids. Their structures were determined ...
The influence of different radiopacifying agents on the radiopacity, compressive strength, setting time, and porosity of Portland cement
(Springer Heidelberg, Heidelberg, 2014)
The aims of this study were to evaluate the radiopacity, compressive strength, setting time, and porosity of white Portland cement (PC) with the addition of bismuth oxide (Bi2O3), zirconium dioxide (ZrO2), and ytterbium ...
Removal of Tc-99(VII) by organo-modified bentonite
(Elsevier, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...

(Nova Science Publishers, Inc., 2014)
Polystyrene, one of the most important material in the modern plastic industry and one of the major synthetic polymer in use today, offers an extremely broad range of applications, due to its good physical properties and ...
Printed antenna with circular polarization and a Tunable elevation angle
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2014)
Circularly polarized antenna with a possibility of tuning the elevation angle i.e. obtaining maximum radiation in either broadside or directions declined from the zenith is presented in the paper. The antenna consists of ...
Design and photocatalytic ability of ordered mesoporous TiO2 thin films
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Homogeneous and crack-free TiO2 films with templated mesoporosity were prepared by the dip coating technique using an evaporation-induced, self-assembly method. The synthesized mesoporous TiO2 films were characterized using ...
