Structure sensitivity of dimethylamine deep oxidation over Pt/Al2O3 catalysts
(Elsevier, 2009)
The deep oxidation of dimethylamine (DMA) was studied over Pt/Al2O3 catalysts with small (1 nm) and large (7.8-15.5 nm) Pt crystallite sizes. The turnover frequency (TOF) was higher for the large than for the small Pt ...
Glassy carbon electrodes: I. Characterization and electrochemical activation
(Elsevier, 2001)
Electrochemical properties of glassy carbon electrodes of two types were examined, one thermally treated at 1000°C (sample K) and another thermally treated at 2500° (sample G). Mechanically polished or electrochemically ...
On the role of working fluid properties in Organic Rankine Cycle performance
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
An exergy composite curves approach for the design of optimum multi-pressure organic Rankine cycle processes
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
This work adopts the (ECCs) under bar (exergy composite curves) approach to explore the potential for ORC (organic Rankine cycle) process improvements. The method is used to explore different ORC configurations supported ...
Kinetics of deep oxidation of n-hexane and toluene over Pt/Al2O3 catalysts Oxidation of mixture
(Elsevier, 2004)
The oxidation of n-hexane and toluene mixtures in air over Pt/Al2O3 catalysts with mean Pt crystallite sizes of 1.0 and 15.5 nm has been studied. Measurements were performed in an external recycle reactor at temperatures ...
The antimicrobial efficiency of silver activated sorbents
(Elsevier, 2015)
This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials ...
Shape evolution of carbon supported Pt nanoparticles: From synthesis to application
(Elsevier, 2016)
In this research, a water-in-oil microemulsion method with HCl as a capping agent was applied to synthesize carbon supported Pt catalysts. Varying the concentration of HCl caused changes in the shape of obtained nanoparticles, ...
Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
Structural and electrochemical properties of the Li2FeP2O7/C composite prepared using soluble methylcellulose
(Elsevier, 2019)
A new method involving the homogeneous dispersion of precursor compounds inside a methylcellulose matrix is used for the synthesis of a composite powder of Li 2 FeP 2 O 7 and carbon. The properties of carbon-containing and ...
Effect of boric acid on the porosity of clay and diatomite monoliths
(Elsevier Sci Ltd, Oxford, 2016)
Porous silica ceramics were obtained at low forming pressure (40-80 MPa) and low sintering temperature (850-1300 degrees C) for 4 h in air. Boric acid was used as a low-cost additive, in the amount of 2 wt%. Relatively ...
