Synthesis and characterization of cation-exchanged laponite nanohybrids for use as drilling fluid viscosifier
In this paper we report our new approach to synthesize cation-exchanged Laponite nanohybrids for use as gel-forming, viscosity and weighting material stabilizing additives for drilling fluid application. To synthesize the nanohybrids, we use laser ablation [...]
Novel Surfactants for Enhanced Oil Recovery
Despite the advent of numerous alternative energy technologies and fuels, the United States will continue to rely heavily on oil, especially from imported sources, to satisfy its energy demand for the foreseeable future. As there [...]
Nanostructured Photocatalytic Approach to CO2 Conversion
Several approaches to stabilize and reduce atmospheric CO2 concentrations have been tested. While carbon capture and storage (CCS) has been hailed as the most promising approach for sequestering CO2 safely away from the atmosphere, the [...]
Economic and Job Impacts of Increased Efficiency in Existing Coal-Fired Power Plants
New Aspects of the Work: We estimated the incremental costs and benefits of coal power plant efficiency improvements and the economic and job implications of these. Conclusions and Main Results: Significant CO2 emissions could be [...]
Economic Assessment of a Conceptual Biomass to Liquids Bio-Syntrolysis Plant
An economic assessment of integrating a High-Temperature Generation Plant (HTGR) with a biomass to SynFuel plant was performed under three market scenarios. Results are as competitive as other carbon feedstock to liquid fuel concepts being [...]
Deuteron Beam Driven Fast Ignition
There are a number of physics issues related to the traditional approach of using a petawatt laser to generate a relativistic electron beam for Fast Igniting inertial confinement fusion (ICF) target. One promising alternate approach [...]
Stability of Aqueous Silica Nanoparticle Dispersions under Subsurface Conditions
The potential application of nanotechnology has significantly advanced into the upstream oil and gas industry. However, harsh subsurface conditions such as high temperature and saline environment are generally incompatible to most commercially available engineered nanoparticles. [...]
Microkinetic Study of Oxygenate and Hydrocarbon Formation from Syngas on Rhodium and Cobalt Surfaces: Effect of Site Structure on Catalytic Cycles
Kapur N., Sampara C., Hao X., Hyun J., Shan B., Nicholas J.B., Davis B., Cho K., Nanostellar Inc., US
Syngas reformation into fuels is an attractive opportunity to diversify away from petroleum and address energy-dependency concerns. Rh and Co-based catalysts used within Fischer-Tropsch (FT) process selectively convert syngas into oxygenates and hydrocarbons respectively but [...]
Nanoparticles: Promising Solution to Overcome Stern Drilling Problems
General solution to overcome stern and frequently occurring drilling problems lies in controlling the rheology of drilling fluids. Pipe sticking, lost circulation, erosion, formation damage, thermal instability, poor hole cleaning, high torque and drag are [...]
High-temperature Desulfurization with Nanosize ZnO
Wang H.P., Wang T.C., Kang H.Y., Wang H.P., Wang T.C., Jou J.G., Wei J.L., National Cheng Kung University, TW
Thermal efficiencies of an integrated gasification combined cycle (IGCC) process can be enhanced with high-temperature desulfurization. Nanosize, sub-nano (clusters) and atomic-dispersed ZnO has been prepared for the high-temperature desulfurization. An enhanced absorbance of the nanosize [...]
The influence of surface termination on growth of cupper clusters
Oxide supported transition metal catalysts are widely used in variety of heterogeneous catalytic processes. Knowledge of the interaction of metals with oxide surfaces provides insight into understanding a broad variety of properties of the catalysts. [...]
