[ 1 ] - مدل‌سازی فرایند تبدیل خشک متان به‌کمک پلاسما با استفاده از شبکه عصبی مصنوعی و الگوریتم ژنتیک
پیش‌بینی فراورده‌های (هیدروژن و کربن مونوکسید) تبدیل خشک متان به‌کمک پلاسما در فشار جوی با استفاده از شبکه عصبی مصنوعی شبیه‌سازی شد. داده‌های تجربی موردنیاز برای مدل‌سازی شبکه عصبی مصنوعی از یک واکنشگاه پلاسمایی تخلیه کرونا جمع‌آوری شد. اثر عامل‌های فرایندی (توان تخلیه پلاسما، دبی خوراک ورودی) بر کارایی تبدیل متان و گزینش‌پذیری نسبت به فراورده‌های مورد بررسی قرار گرفتند. شبکه پیش‌خور با الگوری...
[ 2 ] - Preparation and Characterization of a Novel Biodegradable Epoxy Resin Modified with Epoxidized Oleic Acid
The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...
[ 3 ] - Kinetic Model Study of Dry Reforming of Methane Using Cold Plasma
ABSTRACT In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated ...
[ 4 ] - The Influence of Cation-π Interactions on the Strength and Nature of Intramolecular O...H Hydrogen Bond in Orthohydroxy Benzaldehyde Compound
The influence of cation-π interactions on the strength and nature of intramolecular O...H hydrogen bond has been investigated by quantum chemical calculations in orthohydroxy benzaldehyde (HBA) compound. Ab initio calculations have been performed at MP2/6-311++G** level of theory. Vibrational frequencies and physical properties such as chemical potential and chemical hardness of these compounds...
[ 5 ] - Theoretical Investigation of Interaction between 5-Fluorouracil Anticancer Drug with Various Nitrosamine Compounds
We present detailed theoretical studies of the H-bonded complexes formed from interaction between 5-fluorouracil and various six-membered cyclic nitrosamine compounds. In this study, an investigation on intermolecular interactions in X-NU (X = CH2, SiH2,BH, AlH, NH, PH, O and S) complexes is carried out using density functional theory. The calculations are conducted on B3L...
[ 6 ] - Dry Reforming of Methane Using Cold Plasma; Kinetic Model Study
In this work, the dry reforming of methane was studied using a corona and gliding discharge plasma microreactors. A chemical kinetic model was developed to describe the experimental behavior observed. The kinetic model is proposed based on the assumption that the reactant molecules CH4 or CO2 are attacked by active species produced b...
[ 7 ] - Effect of Graphene Oxide Decorated With Synthesized Nano-CeO2 on Barrier Properties of Epoxy Anticorrosion Coatings
In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed in epoxy resin by sonication. The optimum nanoparticle content of th...
