Abstract Present study aims to highlight the recent developments and challenges associated with catalytic pyrolysis technology for converting municipal mixed plastic waste (MMPW) to valuable hydrocarbon fuels. The study identifies gaps between conventional-thermal and catalytic pyrolysis technologies. Catalyst plays major role in pyrolysis reactions that would reflect yield of liquid product. Scale-up of pyrolysis process with MMPW is viable if catalyst used in the current existing pyrolysis pro...

ABSTRACT It has been expected that mechanical properties of a composite can be enhanced effectively by increasing the content of reinforcing particles to high levels, for which a simultaneous fulfillment of high content and uniform distribution of reinforcing particles is key. In this study, we fabricated Al-TiAl3-Al2O3 composites from starting materials of Al sheets and TiO2 nanopowders by combining accumulative roll-bonding and spark plasma sintering processes. The microstructure and mechanica...

Abstract In recent years, using leaf extract for synthesizing silver nanoparticles (AgNPs) has been introduced as an easy, low-cost, and eco-friendly alternative to chemical and physical methods. In this study, the green synthesis of AgNPs was investigated using Artemisia ciniformis (A. ciniformis) leaf extract and their anti-proliferative and apoptotic effects on human gastric adenocarcinoma (AGS) cell line were evaluated. The properties of green synthesized AgNPs were confirmed using the trans...

Abstract A new two-dimensional (2D) phononic crystal (PC) constituted by the periodic hexagonal lattices, which is inspired by the scissor-like geodesic circle of the Hoberman sphere, is proposed in this study. The band structures, transmission spectrum as well as displacement field of the proposed PC are analyzed by employing the finite element method (FEM) with the Bloch theorem. Furthermore, the formation mechanism of the band gaps (BGs) is investigated according to the eigenmodes at the BG e...

Abstract In this study, the effect of cell structure on the thermal properties of closed-cell foam metals are studied numerically. To do this, a novel modeling procedure is proposed to generate the FEM foam models with different cell structures. The cell size distribution and cell shape in the established models can be controlled by the modeling parameters applied in the modeling process. Two structural parameters termed as characteristic diameter Dch and characteristic shape anisotropy αch are ...

Abstract In this paper, a new low-density (0.40 g/cm3), high-flexibility, high-mechanical property cork composite (RC16) was prepared by using one-component moisture-curing polyurethane U030 as a softwood adhesive. The effects of adhesive content, moisture content of softwood particles and curing conditions on the thermal insulation properties, flexibility and mechanical properties of RC16 composite were investigated. The results show that the synthetic adhesive U030 has excellent compatibility ...

Abstract A series of bimetallic oxides electrode materials were proposed to boost the supercapacitor performance using the density functional theory (DFT) in combination with the electrochemical tests. This work provides a guiding role for exploring energy storage materials with high performance. Based on the plane wave ultra-soft pseudo-potential (PWPP) and general gradient approximate (GGA) in DFT, the electronic and the crystal structures of various strontium bismuth oxides (β-Bi2O3, SrBi2O4,...

Abstract The optimized structures of Cu-mediated metal-DNA parts formed from pyridine(pyridine-2,6-dicarboxylato)copper(II) (Dipic-Cu-Py), pyridine(pyridine-2,6-dicarboxamido)copper(II) (Dipam-Cu-Py), bis(8-hydroxyquinolinato)copper(II) (HQ-Cu-HQ), and N,N′‐ethylenebis(salicylideneiminato)copper(II) (Sal-Cu-Sal) complexes were determined by B3LYP functional with 6-311++G(d,p)-LANL2DZ (Cu) basis sets. The geometric parameters of the mentioned molecules were found and their HOMO, LUMO and NBO anal...

Abstract This paper deals with Ductility Dip Cracking (DDC) during multipass welding of 690 filler metals. In addition to industrial alloys (152 and 52 M), model alloys of controlled purity were also used to unambiguously demonstrate the effect of elemental sulphur and carbon. The sensitivity of each alloy to DDC was measured with the recently developed Refusion Cracking Test (RCT). It is confirmed that the cracks observed in this study result from DDC, not from liquation nor solidification crac...

Abstract Adsorption and dissociation of carbon monoxide on metal clusters M13 (M = Ag, Co, Cu, Fe, Ni and Ru), has been studied. Structure stabilities of metal clusters, adsorption sites, adsorption energies and the activation energies for the dissociation of CO were determined using density functional theory. Cohesive and binding energies of metal atoms in M13 clusters of studied metals were calculated, showing the different strength interaction of metal atoms in each particle. Three active ads...
