Stereoselective transformation of cyclodecene-1,4-dione systems, derived from steroids, to the corresponding spiro-g-lactones. A semiempirical MO Study
(MDPI, 1999)
The thermal and acid-catalyzed intramolecular rearrangement of the (Z)- and (E)-cyclodecene-1,4-dione compounds deriving from steroids, 2a,b and 3a,b, respectively, proceeds stereoselectively to give the corresponding ...
A Novel Two-Step Electrochemical Deposition Method for Sn-Pd Electrocatalyst Synthesis for a Potential Application in Direct Ethanol Fuel Cells
(MDPI, 2023)
Sn-Pd electrocatalysts with a constant atomic ratio of 60 at.% Sn‒40 at.% Pd suitable for
potential application in direct ethanol fuel cells were synthesized using a novel two-step electrodeposition method. First, Sn was ...

Energy decomposition analysis of gauche preference in 2-haloethanol, 2-haloethylamine (halogen = F, Cl), their protonated forms and anti preference in 1-chloro-2-fluoroethane
(Royal Soc Chemistry, Cambridge, 2015)
2-Haloethanol and 2-haloethylamine (halogen = F, Cl) prefer gauche conformation. This preference is significantly increased upon protonation. Commonly used explanations are based on intramolecular hydrogen bonding and ...
Characterization of cobalt ferrite nanoparticles obtained by various synthesis methods and comparison with the Raman spectra of other ferrites and some cubic oxide spinels / Kарактеризација наночестица кобалт ферита добијених различитим методама синтезе и поређење са Рамановим спектрима других ферита и неких кубичних оксидних спинела
(Association for ETRAN Society, 2023)
ingle phase cobalt ferrite (CoFe2O4) with nanoparticles of similar sizes (15.7-19 nm) was obtained by different synthesis methods: coprecipitation, ultrasonically assisted coprecipitation, coprecipitation followed by ...
Essential oil profile of Origanum vulgare subsp. vulgare native population from Rtanj via chemometrics tools

Vibrational and magnetic properties of nano-sized CoFe2O4 obtained by various synthesis techniques: a comparative study
(INOE, Romania, 2023)
Nanocrystalline CoFe2O4 has been synthesized by various synthesis methods. The obtained monodomain nanoparticles are similar in sizes (15.8-19 nm), but with different internal stresses, size distributions and cation inversion ...
The influence of strontium content and sintering temperature on monazite stability
(Association for ETRAN Society, 2023)
This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple ...
