Field Application of Nanoparticle-Based Invert Emulsion Drilling Fluids

Borisov A., Husein M., Hareland G., nFluids, CA

Abstract. Application of nanotechnology in drilling fluids for the oil and gas industry has been a focus of several recent studies (Zakaria et al. 2012; Contreras et al., 2014). Zakaria et al. (2012) developed a [...]

Colloidal Palladium Nanoparticles versus Commercial Palladium Catalysts for Suzuki Cross Coupling Reactions – The Influence of Surface Functionalization

Collins G., ODywer C., Holmes J.D., University College Cork and Tyndall National Institute, IE

The Suzuki-Miyaura reaction is a highly utilised reaction for aryl-aryl bond formation in organic synthesis due it is versatility. The motivation for the application of heterogeneous catalysts in these systems is the easy recovery and [...]

Ultrasensitive mercury sensors based on graphene decorated with nanoparticles

Ayesh A.I., Qatar University, QA

In this work we present a highly sensitive and selective sensor for detection of mercury traces in water. The sensor is constructed by creating interdigitated metal electrodes on a graphene layer placed on SiO2/Si substrate. [...]

Preparation of Photocatalytic Silicon Core-shell Nanoparticles Covered by ZnS Shell in Solid-Gas Reaction

Dvorsky R., Praus P., Svoboda L., Matýsek D., Dropa T., Trojková J., Šollová K., VŠB-Technical University of Ostrava, CZ

For easy handling in some practical processes, active nanoparticles are usually deposited on surfaces of larger carrier particles. In our previous work, the particles of montmorillonite MMT with a mean size of 300 nm served [...]

Polymer nanocomposites reinforced with nanoparticles extracted from renewable resources

Dufresne A., Grenoble institute of technology, FR

There has been an explosion of interest in the use of biomass as a source of renewable energy and materials. One focus of this activity has followed from the recognition that, by suitable chemical and [...]

Adsorption of Functionalized Silica Nanoparticles on Swelling Clay Minerals

Pham H-T, Nguyen Q.P., The University of Texas at Austin, US

Successful application of nanoparticles is dependent on understanding the mobility, retention, and transport fate of nanoparticles in natural formations. These aspects are greatly influenced by subsurface environmental conditions such as electrolyte type and concentration, temperature, [...]

Integration of Flow Batteries into Electric Vehicles: Feasibility and the Future

Katsoudas J.P., Timofeeva E.V., Segre C.U., Singh D., Illinois Institute of Technology, US

Driving range, safety and cost remain the biggest hurdles in the way of mass electric vehicle adoption. To compete with established combustion-engine vehicles, EVs need to have a highly flexible operating capability with minimum downtime. [...]
