Raney Nickel Catalyst – A Molecular Modeling Study

Schweizer S., Chaudret R., Spyriouni T., Low J.J., Subramanian L., Scienomics, US

Porous solid materials are central to various application areas. Due to their specific structural features, they are often used in catalysis, as storage material for hydrogen or small molecules, or as molecular sieves, but they [...]

Study of a Power Source Based on Low Energy Nuclear Reactions (LENRs) Using Hydrogen Pressurized Nanoparticles

Miley G.H., University of Illinois, US

We are studying anomalous heat, attributed to Low Energy Nuclear Reactions (LENRs), generated from metal alloy nanoparticles loaded with hydrogen (or deuterium) through pressurizing the vessel containing the particles [1]. The primary result thus far [...]

A Combined Photoelectrochemical and Theoretical Study to Understand Adsorption Properties of Organic Molecules on TiO2 Surfaces

Sun T., Yunnan University, CN

Titanium dioxide (TiO2) applications in clean energy generation and environmental remediation involve interactions between organic species and TiO2 materials. Such interactions not only depend on the intrinsic properties of TiO2, but also on its surfaces [...]

Ag/Ag3PO4-doped BiPO4 heterostructures and their photocatalytic applications under visible light irradiation

Chen Y.J., Tseng C.-S., Tseng P.-J., Huang C.W., Tseng C.-S., Tseng P.-J., Wu M.-Y., Wu T.H., Lai C.-Y., Wu M.-Y., Wu T.H., Lin Y-W, National Changhua University of Education, TW

Ag/Ag3PO4-doped BiPO4 (Ag/Ag3PO4/BiPO4) heterostructures were synthesized by the hydrothermal method combined with the sonochemical process. Powder X-ray diffractometry, UV–Vis diffuse reflectance spectroscopy, Raman spectroscopy, and transmission electron microscopy were used to characterize the heterostructures. The [...]

Removal of Water Contaminants Using Nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

Propanil, Diuron, Simazine, and Metolachlor are widely used as herbicides and pesticides in California agriculture and across the U.S., and are considered to pose a significant threat to water contamination by transporting chemicals into surface [...]

Catalytic activity of Cu-CeO2-ZrO2 for biodiesel production

Wongvitvichot W., Jampa S., Luengnaruemitchai A., Chaisuwan T., Wongkasemjit S., Chulalongkorn University, TH

Ceria-Zirconia (CeO2-ZrO2, CZ) was synthesized using two different methods, coprecipitation (copre) and nanocasting (nanocast), for using as support material for copper (Cu) catalyst. Cu-CeO2-ZrO2 (CuCZ) was applied for esterification reaction in biodiesel production. Structure and [...]

Cotton Fabric Immobilized AuNP@Graphene and ZnO@rGO for Heterogeneous Catalysis and Photocatalysis

Baruah B., Baruah S., West B., Baruah B., Baruah S., Kennesaw State University, US

The present study demonstrates liquid-phase exfoliation of graphene from pristine graphite in presence of surfactant and synthesis of reduced graphene oxide (rGO) via graphene oxide method. Pretreated cotton fabrics are primed with binder molecules before [...]

Modifications of graphitic C3N4 with multi-metal oxides for enhanced visible-light active photocatalysis

Masih D., Rohani S., University of Western Ontario, CA

Bulk graphitic C3N4 (g-C3N4) is a p-type semiconductor with band gap of 2.7 eV. For photocatalytic water splitting, valance and conduction band gap positions of g-C3N4 sandwich both oxygen and hydrogen evolution potentials, making g-C3N4 [...]
