Catalytic combustion of methane over Pd containing perovskite type oxides
(Elsevier Science Bv, Amsterdam, 2005)
The mixed perovskite type oxides with nominal formula LaTi0.5Mg0.5-xPdxO3, (0 LT = x LT = 0.10) were prepared by anneling the ethanol solution of precursor in nitrogen flow at 1200 degrees C. X-ray powder diffraction ...
Optical characterization of a novel miniature microwave ICP plasma source in nitrogen flow
(IOP Publishing, 2018)
Abstract A Miniature Microwave (MMW) Inductively Coupled Plasma Source (ICP) is characterized by optical emission spectroscopy and by optical imaging of nitrogen plasma. The MWW source operates in two different modes (H – ...
Visible light sensitive mesoporous nanohybrids of lepidocrocite-like ferrititanate coupled to a charge transfer complex: Synthesis, characterization and photocatalytic degradation of NO
(Elsevier, 2018)
The efficiency of photo-oxidation of pollutants catalysed by semiconductors is still limited for real-world applications due to several drawbacks, such as a) insufficient absorption of visible radiation, which predominates ...
Far infrared study of local impurity modes of Boron-doped PbTe
(Springer US, 2012)
PbTe single crystals, doped with B, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and room temperature. The experimental spectra were numerically analyzed, ...
The gadolinium effect on crystallization behavior and luminescence of β-NaYF4:Yb,Er phase
(Wiley, 2020)
Single phase β-NaY0.8-xGdxYb0.18Er0.02F4 nanoparticles with different concentrations of gadolinium ions were prepared via PVP-assisted solvothermal treating at 200°C (PVP- polyvinylpyrrolidone). With the increase in Gd3+ ...
Effect of chemisorbed CO on MoOx-Pt/C electrode on the kinetics of hydrogen oxidation reaction
(Elsevier, 2010)
The influence of poisoning of MoOx-Pt catalyst by CO on the kinetics of H2 oxidation reaction (HOR) at MoOx-Pt electrode in 0.5 mol dm-3 HClO4 saturated with H 2 containing 100 ppm CO, was examined on rotating disc electrode ...
Far infrared reflectivity spectra of lead-telluride doped with Mn and Yb
(INOE Publishing House, 2013)
PbTe single crystal samples doped with Mn and Yb were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with different impurity concentrations (total impurity ...
Triethanolamine as an efficient cosolvent for biodiesel production by CaO-catalyzed sunflower oil ethanolysis: An optimization study
(Hemijska industrija, 2019)
Triethanolamine was applied as an efficient „green“ cosolvent for biodiesel production by CaO-catalyzed ethanolysis of sunflower oil. The reaction was conducted in a batch stirred reactor and optimized with respect to the ...
Structural and electrical properties of geopolymer materials based on different precursors (kaolin, bentonite and diatomite)
(Skopje : Institute of Chemistry, Faculty of Natural Sciences and Mathematics, Ss. Cyril & Methodius University, 2019)
Geopolymers (GP) were successfully synthesized from metabentonite (MB), metadiatomite (MD) and metakaolinite (MK). Characterization of their phase structure and microstructure was performed by XRD, FTIR, SEM/EDX methods. ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
