High frequency ultrasound can enhance olive oil extractability industrially. However, the ultrasound attenuation phenomena and their implications on extractability, are not well understood. This work aims at evaluating the ultrasound attenuation effe

Direct electrochemical response of Myoglobin (Myb) at the basal plane graphite (BPG) electrode was observed when a room temperature ionic liquid (RTIL), 1-(2-hydroxyethyl)-3-methyl imidazolium tetrafluoroborate ([HEMIm][BF4]), was used as the support
Nanocomposite NilZrO 2 -AN catalyst with comparably Sized Ni and ZrO 2 particles is studied in comparison with conventional zirconia-supported Ni catalyst (Ni/ZrO 2 -CP) for the cyclic stepwised steam reforming of methane, which comprises a catalytic

Au/ZrO2 catalysts having only isolated surface Au3 + ions as well as varying percentage of Au3 + ions in the gold were investigated for hydrogenation reactions of 1,3-butadiene, propene, and their mixture at 393 K. Mass specific activity of the isola

Nickel catalysts supported on Al 2 O 3 , SiO 2 , TiO 2 , and two ZrO 2 of different preparations are studied for CO 2 reforming of methane at 1030 K. The results show that the activity and anti-carbon property of the nickel catalyst depend greatly on

ZSM-5 and ZSM-11 zeolites with different contents of aluminum and boron have been synthesized to control their acidity. Results of catalytic studies suggest that there are synergistic effects between framework boron and aluminum to enhance skeletal i

ZnO-NaZSM-5 catalysts with different ZnO loadings (0-17%) are prepared and characterized by various techniques. At low loadings up to 8.3%, highly dispersed clusters of zinc oxide are formed in the pore system of the zeolite. It seems that Na+ in the
