(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
Influence of the gelation and calcination temperatures on physical parameters and photocatalytic activity of mesoporous titania powders synthesized by the nonhydrolytic sol-gel process
(Elsevier, Amsterdam, 2012)
Titania powders were synthesized by nonhydrolitic sol-gel process starting from titanium(IV)-chloride, titanium(IV)-isopropoxide and carbon-tetrachloride. Gelation was performed in solvothermal conditions, at 140 degrees ...
Isopiestic determination of the osmotic and activity coefficients of the {yKNO(3) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and ...
