Magnesium Ion Conducting Polymer Electrolytes: Potential Alternate as Non-lithium Electrolytes for All-Solid-State Battery Applications

Agrawal R.C., Pt. Ravishankar Shukla University, IN

Majority of the portable batteries used today in mobile applications are based on Li+- ion polymer electrolytes and Li-metal electrodes. Li+- salts/Li- metal encounter many serious inherent limitations viz. very reactive, difficult to handle in [...]

Synthesis and characterization of Al-Al2O3/PVDF core-shell nanodieletrics for energy storage

Badi N., Mekala R., University of Houston, US

Extensive interest is being invested into the research of polymer based nanodielectric films. Such a material provides a more practical energy storage solution primarily for embedded capacitors and can be extended for discrete capacitor devices. [...]

Ultrasonically-Assisted Preparation and Functionalization of Graphene

Hielscher K., Hielscher Ultrasonics, DE

Since the extraordinary characteristics of graphite and graphene are known, several methods for its preparation have been developed. Beside to chemical production of graphenes from graphene oxide in multi-step processes, for which very strong oxidizing [...]

Pd/WO3-ZrO2 catalysts: synthesis, characterization and catalytic evaluation

Chen L.F., Ramirez Sebastian S.P., Wang J.A., Instituto Politecnico Nacional, MX

The present work aims at searching for new catalysts for n-heptane isomerization. Four WO3-ZrO2 oxides were prepared by varying WO3 content in 5, 10, 15 and 25 wt% using a sol-gel technique. The 1wt% Pd/WO3-ZrO2 [...]

Structural characterization and photocatalytic activity of electrospun TiO2 and Ce-dopedTiO2 nanofibers

Sang-urai S., Worayingyong A., Mansiri S., Smith M.F., Seraphin S., Kasetsart University, TH

Mixed phase TiO2 and Ce-doped TiO2 nanofibers with different content (0.5, 2.0, 8.0%) ofcerium ions were prepared by a sol-gel electro-spinning method. Results from SEM showed nobeads on the undoped-TiO2 and Ce-doped TiO2 nanofibers with [...]

The effect of promoters on reduction of Ru/ZrO2/Co/SiO2 catalyst for Fischer-Tropsch synthesis as studied by in situ XANES.

Kangvansura P., Poo-arporn Y., Schulz H., Worayingyong A., Kasetsart University, TH

AbstractRu/ZrO2/Co/SiO2 was prepared via a co-precipitation and an incipient wetnessimpregnation methods and characterized by XRD and XANES. To study the effect ofpromoters on reduction of active cobalt species on the catalyst, Ru/ZrO2/Co/SiO2,ZrO2/Co/SiO2, Ru/Co/SiO2, and Co/SiO2 [...]

Synthesis and Characterization of Nanocomposites Using the Nanoscale Laser Soldering in Liquid Technique

Phuoc T.X., Mcintyre D., Song X., Chyu M.K., National Energy Technology Lab, US

It has been known that catalytic and sensing properties of semiconductor and metal nanoparticles (NPs) can be greatly enhanced if they are made in the form of nanocomposites. For that reason, in this work, we [...]

Mesoporous Zirconia Supported Nickel Catalysts for Coke Minimization in Dry Reforming of Methane

Mustu H., Arbag H., Yasyerli N., Yasyerli S., Yasyerli N., Yasyerli S., Dogu G., Dogu T., Dogu G., Dogu T., Gazi University, TR

Dry reforming of methane is a promising route for conversion of two of the most abundant greenhouse gases to syngas. Ni based catalysts are generally preferred due to low cost and good activity. However, significant [...]

From Synthesis Gas to a Clean Transportation Fuel Dimethyl Ether: New Nanocomposite Bifunctional Catalyst Pairs

Arslan A., Bayat A., Celik G., Dogu T., Middle East Technical University, TR

Diemethyl ether (DME) is a promising diesel fuel alternative due to its high cetane number and clean burning properties. Direct synthesis of DME from syngas has major thermodynamic advantages over the conventional process. Technological development [...]
