[ 1 ] - Novel PVA/La2Ce2O7 hybrid nanocomposite membranes for application in proton exchange membrane fuel cells

Proton exchange membrane fuel cells (PEMFCs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. In this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/La2Ce2O7 (PVA-LC) with the aim of increasing the water uptake and proton conductivity. Glutaraldehyde (GA) was used as cross linking agent ...

[ 2 ] - Sol-gel synthesis, characterization, optical properties and catalytic performance of Y2Ce2O7 nanomaterial

Y2Ce2O7 nano powders were synthesized via sol-gel reactions at 900 (S1), 1000 (S2) and 1100 (S3) ˚C for 4 h using yttrium acetate (C6H9O6Y.xH2O), ammonium cerium nitrate ((NH4)2Ce(NO3)6) and stearic acid (C18H36O2</s...

[ 3 ] - Synthesis, characterization and optical band gap of Lithium cathode materials: Li2Ni8O10 and LiMn2O4 nanoparticles

Li2Ni8O10 and LiMn2O4 Nanoparticles as cathode materials of lithium ion battery, were successfully synthesized using lithium acetate, nickel and manganese acetate as Li, Ni and Mn sources and stearic acid as a complexing reagent. The structure of the obtained products were characterized by FT-IR and XRD. The shape, size and distribution of the Li2Ni8O10 and LiMn2O4 nanoparticles were observed b...

[ 4 ] - Synthesis and characterization of Barium Strontium Titanate (BST) micro/nanostructures prepared by improved methods

Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over the other methods. Low processing temperature is a desired point which most of...
