Effect of the activator type and catalyst/activator ratio on physical and mechanical properties of cast PA-6
(2008)
The aim of the study is to produce suitable unfilled cast polyamide-6 composition exhibiting optimum mechanical, physical, thermal and electrical properties with anionic polymerization mechanism. Sodium lactamate was used ...
Hydrogen storage properties of mono-and bidentate MOF structured orotate complexes
(Materials Research Society, 2014)
One of the barriers for wide usage of hydrogen energy system is efficient storage. To store more hydrogen efficiently, physisorption is a choice among the others with high storage performance, reversibility, and lifecycles. ...
Treatment of petroleum refinery effluent using ultrasonic irradiation
(De Gruyter Poland Sp Zoo, 2018)
Ultrasonic irradiation is one of the advanced oxidation methods used in wastewater treatment. In this study, ultrasonic treatment of petroleum refinery effluent was examined. An ultrasonic homogenizator with a 20 kHz ...
Determination of Mechanical Properties of Composite Supports Used in Catalytic Membranes for Hydrogen Production and Separation
(Wiley-V C H Verlag Gmbh, 2020)
This study includes the determination of mechanical properties involving equibiaxial flexural strength, elastic modulus, strain and hardness for composite supports developed to be used in catalytic membranes in order to ...
Synthesis of APTES and alcohol modified Sn/SBA-15 in presence of competitive ion: Test in degradation of Remazol Yellow
(Elsevier Ltd, 2022)
Sn/SBA-15s were prepared hydrothermally either disolving metals in EA (ethyl alcohol) or/and APTES (3-aminopropyl triethoxysilane) modification of TEOS (tetraethyl ortosilicate) under aluminum competition. Proposed synthesis ...
Thermal and mechanical characterization of composite produced from recycled PE and flue gas desulfurization gypsum
(SAGE Publications Ltd, 2019)
Varying ratios of industrial byproduct of flue gas desulfurization gypsum and recycled polyethylene were used to prepare composite matrices in order to develop an eco-friendly material. Small ratios of maleic anhydride ...
Computational screening of zeolite templated carbons for hydrogen storage
(Elsevier B.V., 2022)
Grand Canonical Monte Carlo (GCMC) simulations were used to evaluate the hydrogen storage performance of the 68 stable ZTCs which were recently identified. The relationship between the hydrogen storage capacities and ...
Effect of boiling point and density prediction methods on stochastic reconstruction
(American Chemical Society, 2018)
Stochastic reconstruction (SR) methods are used to generate a series of molecules that mimic the properties of complex mixtures using partial analytical data. Determining a quantitative composition using these methods is ...
Blend membranes of sulfonated poly (ether ether ketone) and thermoplastic poly (urethane) for fuel cells
(Springer, 2019)
Membranes used in polymer electrolyte membrane fuel cells (PEMFCs) have critical importance because their properties directly affect the performance of fuel cell. For this purpose, blend membranes based on sulfonated poly ...
Encapsulation of CuO nanoparticles inside the channels of the multi-walled carbon nanotubes functionalized with thermal stress
(Elsevier Science Sa, 2021)
Commercially available multi-walled carbon nanotubes (MWCNTs), which are generally naturally intertwined, were cut by sudden, repeated exposure to oxidizing conditions in the air. This process has been proved to be an ...
