Fabrication and Design of Carbon Nanomaterials Based Scale Monitoring Smart Sensor Systems

Younes H., Jelbuldina M., Sofela S.O., Tizan L., Al Ghaferi A., Saadat I., Masdar, AE

Scale is the creation of inorganic soluble salts from aqueous brines during oil and gas production. The scale deposits at the internal surface of the pipelines under the supersaturation conditions. The deposition of the scale [...]

Inert, Corrosion Resistant CVD Coating for Oil and Gas Service

Mattzela J.B., Smith D., Yuan M., Higgins M., Barone G., SilcoTek Corporation, US

Estimates of the cost of corrosion within US industries often exceed $150 billion. Challenges within the often complicated production techniques of the oil and gas industry have led to increased efforts to control these costs. [...]

Development of New Surfactants for CO2 Foam Enhanced Oil Recovery

Nguyen Q.P., Ren G., The University of Texas at Austin, US

Sweep efficiency in CO2 enhanced oil recovery processes are major problem owing to the unfavorable mobility of CO2. One method of controlling CO2 mobility is through the use of foam. CO2 foam in the past [...]

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 [...]

Multifunctional Nanocomposites for Oil and Gas

Sherman A., Powdermet Inc/Terves Inc, US

The ability to design and manufacture highly engineered multiphase materials enables the independent (actually interdependent) control over physical and mechanical properties, and kinetic response of structural materials. The production of "materials that do more" offer [...]

Computational study of structural dependence of catalytic properties of Pt-Ru nanoalloy catalysts

Prasai B., Petkov V., Central Michigan University, US

Metal nanoparticles (NPs), composed of single-type metals and multiple-type metals, have attracted a great deal of interest in the research community since such NPs are key components in many useful applications such as catalytic, magnetic [...]

Hydrogen generation by ammonia decomposition using Co supported on Mg/La mixed oxide: Effect of calcination atmosphere of support

Podila S., Driss H., Alhamed Y.A., Al-Zahrani A., Petrov L.A., King Abdulaziz University, SA

Generation of COx free hydrogen by ammonia decomposition (AD) is more attractive from practical and economical perspectives compared to other process. Previous studies showed that Ru supported on multi wall carbon nanotubes (MWCNTs) is the [...]

Catalytic Decomposition of Methanol Effected by Cu-ZnO@C Nanoreactors

Hong C.-I., Peng C.-Y., Wei Y-L, Jou C.-J.G., Sun I.-W., Paul Wang H., National Cheng Kung University, TW

Decomposition of methanol (DM) to CO and H2 can be catalyzed by Cu-ZnO@C core-shell and Cu-ZnO○yC yolk-shell nanoreactors at 473-573 K. It is found that the reactivity of DM catalyzed by the nanoreactors increases with [...]

Evolution of self-assembled Bi2O3/LDHs nanostructures to mixtures of mixed oxides and their photocatalytic efficiency under UV and solar light

Katsumata K-I, Puscasu M., Seftel E., Grosu E.F., Ikeda K., Cool P., Carja G., Technical University Gheorghe Asachi of Iasi, RO

Self-assemblies of nanoparticles of Bi2O3 and the clay matrices of layered double hydroxides (LDHs) were fabricated using the manifestation of the structural memory effect of the LDHs in Bi(NO3)3 aqueous solutions, at room temperature. Nanoparticles [...]

On the behavior of modified TiO2 nanotubes for a photoanode-driven photoelectrochemical reduction of CO2

Palmas S., Università degli studi di Cagliari, IT

Carbon dioxide is one of the main greenhouse gases responsible for global warming. Due to the high costs of its disposal, many efforts have recently been addressed to its reuse: converting CO2 to valuable compounds [...]
