In this study, incorporation of iron ion-doped natrolite nanozeolite, multi-wall carbon nanotubes into chitosan-coated glassy carbon electrode for the simultaneous determination of ascorbic acid, epinephrine, uric acid and tyrosine is studied. The results show that the combination of multi-wall carbon nanotubes and iron ion-doped natrolite zeolite causes a dramatic enhancement in the sensitivit...

A PEBAX-nano zeolite X mixed matrix membrane was fabricated and operationally characterized using single gas (CO2) permeation. X-ray diffraction (XRD) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. The membranes were characterized by scanning electron microscopy (SEM) to study cross-sectional morphology. The single gas permeability were carried...

Polyurethane/zeolite 13X nanocomposite films were fabricated using solution casting method. The synthesized nanocomposite films were structurally characterized using SEM, TGA and tensile analysis. SEM images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. Better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...

Nano-sized protonated ZSM–5 ( H-ZSM-5nanozeolite) was successfully synthesized by the hydrothermal method using the bagasse ash (BGA) as a new silica source. Cultivated BGA in the south of the Caspian Sea (Mazandaran province, Iran) was used for extracting silica powder. H-ZSM-5 was characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electronic microscopy (SEM...

a pebax-nano zeolite x mixed matrix membrane was fabricated and operationally characterized using single gas (co2) permeation. x-ray diffraction (xrd) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. the membranes were characterized by scanning electron microscopy (sem) to study cross-sectional morphology. the single gas permeability were carried out for ne...

Experimental process The one-pot DKR of racemic 1-PE was carried out in a glass reactor with a magnetic stirring under microwave irradiation at a desired temperature. Typically, racemic 1-PE (0.10-0.4 mmol) and acyl donor (0.20-0.8 mmol) were firstly added into n-hexane (4.0 mL). And then, 20 mg of the core-shell bi-functional catalysts (Hβ-PDDA@CALB)MSs were added into the above-mentioned reac...
