Influence of diesel acidification on dibenzothiophene removal: A new desulfurization practice
(
Elsevier
, 2015 , Article)
Commercial diesel is often loaded with organosulphur compounds including hard-to-remove dibenzothiophene DBT and other derivatives. Following uncommon and simple procedure, dibenzothiophene was selectively removed upon ...
A novel desulfurization practice based on diesel acidification prior to activated carbon adsorption
(
Springer New York LLC
, 2015 , Article)
Commercial diesel is often rich with organosulfur compounds and a value of 7,100 mgS/kg was recently reported. As confirmed by chromatographic analysis, about 36% of sulfur compounds are originated from dibenzothiophene. ...
Insights into the remediation characterization of modified bentonite in minimizing organosulphur compounds from diesel fuel
(
Korean Society of Industrial Engineering Chemistry
, 2015 , Article)
In this work, physical and chemical characteristics of the raw, treated, and acid activated bentonite were investigated using XRD, FTIR, scanning electron microscopy (SEM), and differential thermal analysis (DTA)/thermogravimetry ...
العبء المذهبي : العوامل الحاكمة للسياسة الإيرانية تجاه العالم العربي
(
مؤسسة الأهرام
, 2015 , Article)
تعد إيران من أكثر الدول إثارة للجدل في منطقة الشرق الأوسط، نظرا للتصور الموجود حول تأثيرها، وكذلك التطورات السياسية التي شهدتها منذ القرن السادس عشر، وظهور هوية دينية مذهبية لها متمايزة عن بقية العالم الإسلامي. يرتبط هذا ...
Cellulose assisted combustion synthesis of porous Cu-Ni nanopowders
(
Royal Society of Chemistry
, 2015 , Article)
Porous nanopowders of Cu-Ni were synthesized using cellulose fibres as impregnation media at ambient pressure using combustion based techniques. The synthesized nanopowders were characterized using XRD, BET, SEM, TEM etc. ...
Solar hydrogen production via thermochemical iron oxide-iron sulfate water splitting cycle
(
Elsevier Ltd
, 2015 , Article)
This paper reports the thermodynamic analysis of solar H2 production via two-step thermochemical iron oxide–iron sulfate (IO–IS) water splitting cycle. The first step belongs to the exothermic oxidation of FeO via SO2 and ...
Microstructure and properties of sol-enhanced Ni-Co-TiO2 nano-composite coatings on mild steel
(
Elsevier Ltd
, 2015 , Article)
Abstract Ni-Co-TiO2 nano-composite coatings were electroplated on mild steel by adding transparent TiO2 sol (0-50 mL/L) into the Ni-Co plating solution. The microstructure, mechanical property and corrosion resistance of ...
Preparation and property of duplex Ni-B-TiO2/Ni nano-composite coatings
(
World Scientific Publishing Co. Pte Ltd
, 2015 , Article)
The duplex Nickel-Boron-Titania/Nickel (Ni-B-TiO2/Ni) coatings were deposited on mild steel by using two baths with Ni as the inner layer. TiO2 nanoparticles were incorporated into the Ni-B coatings as the outer layer by ...
Duplex Ni-P-ZrO2/Ni-P electroless coating on stainless steel
(
Elsevier Ltd
, 2015 , Article)
Duplex Ni–P–ZrO2/Ni–P coating was electroless deposited onto stainless steel substrates. High phosphorus Ni–P coating was plated as the inner layer to improve the corrosion resistance and low phosphorus sol-enhanced Ni–P–ZrO2 ...
Correlated Multiple Antennas Spectrum Sensing under Calibration Uncertainty
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
We address the problem of spectrum sensing in cognitive radios (CRs) when the secondary user (SU) is equipped with a multiantenna receiver. We consider scenarios with correlation between the received channels at different ...
