Preparation and characterization of poly(Urethane-siloxane)/titanium-dioxide nanocomposites
(Association of the Chemical Engineers of Serbia, 2019)
This work is focused on preparation of poly(urethane-siloxane)/titanium-dioxide nanocomposites (PUSNs) with enhanced features. PUSNs were prepared by the in situ polymerization reaction using titanium-dioxide as a nano-filler ...
Kinetic properties of the Ti-Ni intermetallic phases and alloys for hydrogen evolution
(Lausanne : Elsevier Science Sa, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared ...
Ideal efficiency of resonant cavity-enhanced perovskite solar cells
(Springer Science and Business Media LLC, 2020)
Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost ...
Influence of dimensionality on phase transition in VO2 nanocrystals
(Belgrade : International Institute for the Science of Sintering, 2013)
Hydrothermally synthesized one-dimensional and two-dimensional nanocrystals of VO2 undergo phase transition around 65°C, where temperature and mechanism of phase transition are dependent on dimensionality of nanocrystals. ...
Investigation of sintering kinetics of NiO using photo acoustic spectroscopy
(Belgrade : International Institute for the Science of Sintering, 2004)
Sintering kinetics of NiO was investigated using photo acoustic spectroscopy This method was used to follow the change of phase and amplitude of the photo acoustic signal of nickel-oxide samples sintered at 1373 K for ...
Synthesis of poly(ɛ-caprolactone) nanospheres in the presence of the protective agent poly(glutamic acid) and their cytotoxicity, genotoxicity and ability to induce oxidative stress in HepG2 cells
(Elsevier, 2014)
Nanospheres of poly (ɛ-caprolactone) (PCL) with sizes smaller than 200 nm were produced by combining the freeze drying method and the physicochemical solvent/non-solvent approach. The influence of various types of ...
Dielectric characteristics of donor-acceptor modified BaTiO3 ceramics
(Elsevier, 2016)
Sm/Mn codoped BaTiO3 ceramics were investigated for their microstructure and dielectric characteristics. The powders were prepared by the conventional solid state procedure. The concentration of Sm2O3 as a donor dopant has ...
Insertion of lithium ion in anatase TiO2 nanotube arrays of different morphology
(Elsevier, 2017)
Anatase TiO2 nanotube arrays of different morphology were prepared by a two-step process: anodic oxidation at voltages 20–60 V and subsequent annealing at 400 °C. By amplifying anodization voltage the inner diameter of ...
Synthesis, characterization and electrocatalytical behavior of Nb-TiO2/Pt nanocatalyst for oxygen reduction reaction
(Elsevier, 2010)
In order to point out the effect of the support to the catalyst for oxygen reduction reaction nano-crystalline Nb-doped TiO2 was synthesized through a modified sol-gel route procedure. The specific surface area of the ...
Ni-(Ebonex-supported Ir) composite coatings as electrocatalysts for alkaline water electrolysis. Part II: Oxygen evolution
(International Journal of Hydrogen Energy, 2016)
The oxygen evolution reaction (OER) was studied at pure Ni and Ni-(Ebonex/Ir) composite coatings in 1 M NaOH solution at 25 °C. Ni-(Ebonex-supported Ir) coatings were electrodeposited from a nickel Watts bath containing ...
