Photocatalytic disinfection of E. coli using tourmaline-N-doped TiO2 composite

Tzeng J-H, Lin Y.-T., Weng C-H, National Chung Hsing University, TW

Neither the microbicidal mechanism of TiO2 under visible radiations nor their potential effects in the light intensity have yet been well established. In this paper, the photocatalytic inactivation of bacteria was investigated using E. coli, [...]

Synthesis of nano-hydroxyapatite from a biogenic waste for the removal of manganese from wastewater

Amuda O.S., Sanni K.A., Kolawole L.L., Ladoke Akintola University of Technology, NG

A novel Hydroxyapatite nanopowder prepared from a biogenic waste, shell of a gastropod, by hydrothermal method was used for adsorption of manganese ion in wastewater. The nano-Hap produced was characterized using XRD, FTIR and SEM. [...]

Fabrication and Testing of a Miniaturised Water Quality Monitoring pH and Conductivity Sensors

Banna M.H., Najjaran H., Sadiq R., Rodriguez M.J., Imran S.A., Hoorfar M., University of British Columbia, CA

Development of cost-effective, durable and sensitive on-line water quality monitoring sensors that can be installed across the water distribution network has attracted attentions to increase the frequency of monitoring and hence reduce the risk of [...]

An integrated approach for industrial water systems optimal design

Porzio G.F., Alcamisi E., Matino I., Colla V., Scuola Superiore Sant'Anna, IT

A novel approach is presented for integration of traditional water pinch technology to include detailed waste-water treatment systems models. The theoretical framework as well as examples for practical application of the novel approach will be [...]

Innovative Treatment of Shale Fracturing Flowback and Produced Water for Reuse or Discharge

Pakzadeh B., Mastin B., Chatterton B., Vaillancourt A., Renew J., Wos J., Philbrook D., Min J., Wardle C., Southern Research Institute, US

Southern Research Institute, with project partners M2 Water Treatment, Inc. and BKT United received an award from Research Partnership to Secure Energy for America to develop an innovative, cost-effective, and robust approach for shale fracturing [...]

Conformance Control through In-situ Gelation of Silica Nanoparticles

Rankin K.M., Nguyen Q.P., The University of Texas at Austin, US

Due to reservoir heterogeneities, oil recovery from fluid injection during secondary and/or tertiary recovery does not occur in an ideal piston-like displacement. Rather sweep efficiency can be much lower than 100% due to heterogeneities such [...]

Molecular Dynamics Simulation of Adsorption from Microemulsions and Surfactant Micellar Solutions at Solid-Liquid, Liquid-Liquid and Gas-Liquid interfaces

Akkutlu Y., Bui K., Silas J.A., Zelenev A., Saboowala H., Texas A&M University, US

In enhanced oil and gas recovery, the production of hydrocarbons is influenced by the ability of injected surfactants to adsorb and to modify interfacial tension at different interfaces. It has been demonstrated that surfactant and [...]

Nanocoating Testing for High Voltage Transmission Applications

McGuire D., Phillips A., Engelbrecht C., Gould A., Southern Company, US

The availability of reliable and affordable electric power is one of the most important characteristics of a modern society. Each citizen of the modern world has the expectation of light at the touch of a [...]

Nanotechnology in steel tubular goods: Challenges and Prospects

Castro P.A., Tenaris, AR

While traditional tubular steel tubular goods manufacturing and finishing technologies are getting closer to their limits, nanotechnology offers unique opportunities to achieve these new demands. It is in the field of coatings and nanostructured surfaces [...]

Surfactants Nanocarriers to Enhanced oil Recovery (EOR)

Nascimento R.S.V., UFRJ, BR

The use organic surfactant nanocarriers as interfacial tension reducing agents is proposed in this work. These particles are able to permeate into the pores of the reservoir and release the surfactant by solubilization of the [...]
