; Uplift behavior and load transfer mechanism... of pile foundations. A field-scale test program was conducted to study the uplift behavior and load transfer mechanism of PHC piles in soft soil. The pullout load tests were divided into two groups......
In situ reaction mechanism of MgAlON in Al–Al2O3–MgO composites at 1700°C under flowing N2Shang-hao Tong,Yong Li,Ming-wei Yan,Peng Jiang,Jia-jia Ma,Dan-dan YueSchool of Materials Science... as M1, M2, and M3, respectively, were prepared at 1700°C for 5 h under a flowing N2 atmosphere using the reaction sintering method. After sintering, the Al–Al2O3–MgO composites were characterized......
; reaction mechanism 1 Introduction Hydrous chromium oxides (Cr2O3·xH2O) such as chromium hydroxide (Cr(OH)3) and chromium oxyhydroxide (CrOOH) offer a near-ideal combination of distinctive adsorption... and SEM show that the hydrolysis reaction can be realized at a low reaction temperature of 80 °C and a reaction time of 24 h. Moreover, the greyish-green α-CrOOH with a hexagonal plate-like morphology......
. The physicochemical properties of catalysts were characterized by SEM, BET and XPS measurements, the reaction and deactivation mechanism of V2O5/TiO2 were also analyzed and discussed. The results indicate... with the contents of chemical adsorbed oxygen and the ratio of w(V4+)/w(V5+) on the surface of catalysts. Key words: commercial V2O5/TiO2 catalysts; sodium poisoning; regeneration; reaction mechanism......
