LaBO3 with various particle sizes have been successfully prepared by microwave-assisted combustion and sol-gel synthesis methods. Urea, citric acid and glycine have been used as fuels during the synthesis process. Characterizations were done by X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) Spectroscopy, Photoluminescence Excitation and Emission Spectroscopies, Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). The SEM micrographs show dissimilar morphologies of powders with different particle sizes. Luminescent properties of 2.5%, 5.0%, and 7.5% Eu doped LaBO3 synthesized with three different fuels were compared. The results showed that a 5% level is the critical doping amount for all, and the one synthesized with urea gives rise to the stronger emissions compared to others.

Microwave absorbing property of epoxy resin composites with added Fe3O4 nanoparticles
Hashimov, Arif Mamed; Tabatabaei, Naser Mahdavi; Samedova, Ulker Farruk; Nuriyev, Musa Abdulali; Bayramov, Mazahir Nasraddin; Mehrabov, Amdulla (2019-01-01)
In this paper, we have successfully synthesized nanoparticles of Fe3O4 and composites based on epoxy resin with various mass ratios of nanomagnetite were prepared. The structure, morphology and properties of the composites were characterized with X-ray diffraction, scanning electron microscope. Results of measurements of reflection coefficients (R), transmission (T), and absorption (A) of the ER series composites of composites on basis of nano magnetite are presented in this paper.
Oxygen plasma modification of polyurethane membranes
Ozdemir, Y; Hasırcı, Nesrin; Serbetci, K (2002-12-01)
Polyurethane membranes were prepared under nitrogen atmosphere by using various proportions of toluene diisocyanates (TDI) and polypropylene-ethylene glycol (P) with addition of no other ingredients such as catalysts, initiator or solvent in order to achieve medical purity. Effects of composition on mechanical properties were examined. In general, modulus and UTS values demonstrated an increase and PSBR demonstrated a decrease as the TDI/Polyol ratio of the polymer increased. Elastic modulus, ultimate tensi...
Clean and efficient microwave-solvent-free conversion of homochiral amines, alpha-amino alcohols and alpha-amino acids to their chiral 2-substituted pyrrole derivatives
Aydogan, F; Demir, Ayhan Sıtkı (Elsevier BV, 2005-03-21)
Efficient synthesis of 1,2-disubstituted homochiral pyrroles has been achieved by a two-component coupling of chloroenones and amine compounds on the surface of silica gel without any solvent under microwave irradiation.
Coke Minimization in Dry Reforming of Methane by Ni Based Mesoporous Alumina Catalysts Synthesized Following Different Routes: Effects of W and Mg
ARBAĞ, HÜSEYİN; YAŞYERLİ, SENA; YAŞYERLİ, NAİL; Doğu, Timur; DOĞU, GÜLŞEN (Springer Science and Business Media LLC, 2013-12-01)
Ni based mesoporous alumina (MA) catalysts were synthesized by sol-gel (SGA) and hydrothermal (MA) methods, following impregnation and one-pot synthesis routes and catalytic performances of these materials were tested in dry reforming of methane. Results proved the importance of synthesis procedure of the MA supports on the activity and coke resistance of the synthesized materials, containing 16 % Ni. Among these catalysts, MA prepared by the sol-gel technique (Ni@SGA) showed the highest activity in dry ref...
Nano-organic carbon and soot particle measurements in a laminar ethylene diffusion flame
D'Anna, A; Rolando, A; Allouis, Christophe Gerard; Minutolo, P; D'Alessio, A (2005-01-01)
The formation of carbonaccous particulates in a co-flow laminar diffusion flame has been studied using UV-visible spectroscopy and laser scattering/extinction techniques for measurements of volume fractions and particle sizes. Measurements were performed in a non-smoking ethylene-air flame at atmospheric pressure. UV-visible spectroscopy allowed the identification of two classes of particles: soot particles, which absorb light in the whole spectral range and nano-organic carbon particles (NOC) which are tra...
