Effect of the support on physicochemical properties and catalytic performance of cobalt based nano-catalysts in Fischer-Tropsch reaction
(
Elsevier Ltd
, 2017 , Article)
In this paper, comparative investigations of the effects of CNTs and ?-Al2O3 on the physicochemical properties and catalytic performances of Co based nano-catalyst during FTS have been presented. Catalysts were prepared ...
Drastic difference between hole and electron injection through the gradient shell of Cd: XSeyZn1- xS1- y quantum dots
(
Royal Society of Chemistry
, 2017 , Article)
Ultrafast fluorescence spectroscopy was used to investigate the hole injection in CdxSeyZn1−xS1−y gradient core–shell quantum dot (CSQD) sensitized p-type NiO photocathodes. A series of CSQDs with a wide range of shell ...
Synthesis and characterization of poly(vinyl alcohol): Cloisite 20A nanocomposites
(
John Wiley and Sons Ltd
, 2017 , Article)
Polymeric nanocomposite materials are very important materials because of their promised applications. However, many of their fundamental physical, mechanical, and chemical behaviors have not been quantified. Depending on ...
Tailoring Organic Cation of 2D Air-Stable Organometal Halide Perovskites for Highly Efficient Planar Solar Cells
(
Wiley-VCH Verlag
, 2017 , Article)
2D perovskites have recently been shown to exhibit significantly improved environmental stability. Derived from their 3D analogues, 2D perovskites are formed by inserting bulky alkylammonium cations in‐between the anionic ...
Fuzzy Logic-Based Model to Predict the Impact of Flow Rate and Turbidity on the Performance of Multimedia Filters
(
American Society of Civil Engineers (ASCE)
, 2017 , Article)
This paper uses fuzzy logic-based models to predict and evaluate the performance of multimedia filters utilized in wastewater treatment. A fuzzy logic-based model is constructed and trained to predict the operating time ...
Optimization of cultivation conditions for combined nutrient removal and CO2 fixation in a batch photobioreactor
(
John Wiley and Sons Ltd
, 2017 , Article)
BACKGROUND
The application of Chlorella vulgaris for simultaneous CO2 biofixation and nutrient removal has been optimised using response surface methodology (RSM) based on Box Behnken design (BBD). Experimental conditions ...
Review on Surfactant Flooding: Phase Behavior, Retention, IFT, and Field Applications
(
American Chemical Society
, 2017 , Article Review)
Surfactant flooding is an important technique used in enhanced oil recovery to reduce the amount of oil in pore space of matrix rock. Surfactants are injected to mobilize residual oil by lowering the interfacial tension ...
Fabrication of polysulfone nanocomposite membranes with silver-doped carbon nanotubes and their antifouling performance
(
John Wiley and Sons Inc.
, 2017 , Article)
In this study, polysulfone (PSf)/silver-doped carbon nanotube (Ag-CNT) nanocomposite membranes were prepared by a phase-inversion technique; they were characterized and evaluated for fouling-resistant applications with ...
Large CO2 uptake on a monolayer of CaO
(
Royal Society of Chemistry
, 2017 , Article)
Density functional theory calculations are used to study gas adsorption properties of a recently synthesized CaO monolayer, which is found to be thermodynamically stable in its buckled form. Due to its topology and strong ...
Corrosion behavior of API X100 steel material in a hydrogen sulfide environment
(
MDPI AG
, 2017 , Article)
Recently, the API X100 steel has emerged as an important pipeline material for transportation of crude oil and natural gas. At the same time, the presence of significant amounts of hydrogen sulfide (H2S) in natural gas and ...
