to investigate the role of silicon (si) in alleviating the effects of salinity on quality and quantity of cut rose flowers ‘hot lady’cultivar was grown in hydroponic culture media. different levels of silicon (0, 50, 100 and 150 mg l-1) as si were mixed with 28 mm nacl (ec ≈3.8 ds m-1) levels, used in an rcbd experimental design.the results indicated that si in 50 and 100 mg l-1 had beneficial ...
In this work, SrO buffer layers were employed as an interface engineering approach to realize single crystalline mixed ternary rare earth bixbyite oxide (RE2O3) films on Si (001) substrate. Single crystalline mixed PrxY2-xO3 (x=0-2) has been successfully grown on Si (111) (Ref. 7). However, the formation of such mixed oxide can only be realized at >750 °C, therefore when it is directly grown on...
A simple and general procedure has been developed for the syntheses of ordered largepore (up to 14 nm) mesoporous metal oxides, including TiO2, ZrO2, Nb2O5, Ta2O5, Al2O3, SiO2, SnO2, WO3, HfO2, and mixed oxides SiAlOy, Al2TiOy, ZrTiOy, SiTiOy, ZrW2Oy. Amphiphilic poly(alkylene oxide) block copolymers were used as structure-directing agents in nonaqueous solutions for organizing the network-form...
