TPD-MS study of glassy carbon surfaces oxidized by CO2 and O2 / Maseno spektrometrijsko ispitivanje stabilnosti površine staklastog karbona oksidovanog ugljen-dioksidom ili kiseonikom
(Serbian Chemical Society, Belgrade, 2002)
The temperature-programmed desorption (TPD) method combined with mass spectrometric (MS) analysis has been applied to investigate the surface properties of carbon materials. The apparatus consisting of a temperature-programmed ...
A comparative study of two wool enzyme treatments
(Niscair, 2002)
The influence of enzyme concentration and treatment time on certain wool properties has been studied according to the Box-Hunter experimental design in order to better understand the wool modification caused by two different ...
Inverse gas chromatrography of chromia. Part II. Finite surface coverage / Inverzna gasna hromatografija na hrom(III)-oksidu. Deo II
(Serbian Chemical Society, Belgrade, 2002)
The interactions of n-hexane, benzene, chloroform, and tetrahydrofuran with dried (amorphous) chromia (I) and chromia heated at 1073 K (crystalline) (II), both obtained from a colloidal dispersion, and a commercially ...
Thermal shock behavior of alumina based refractories
(Techna Srl, Faenza, 2002)
Temperature difference and fracture resistance parameters have been used to predict the thermal shock behavior. Alumina based commercial refractories with different content of Al2O3 from 28% to 78% were used. Thermal and ...
