Abstract
In the present study, we systematically investigated the effect of entropy of mixing (ΔS_mix) on the mechanical and thermal properties of single phase FCC solid solutions with multi-principal elements. An increase in ΔS_mix led to an increase in micro-hardness and a decrease in thermal conductivity (κ) due to severe lattice..... More

Abstract
Fe-TiB₂ powder was synthesized in-situ by the planetary ball milling and subsequent heat-treatment of an iron boride (FeB) and titanium hydride (TiH₂) powder mixture. Mechanical activation of the (FeB+TiH₂) powder mixtures was observed after a milling time of 3 hours at 700 rpm of rotation speed, but activation was not..... More

Plastic Working & Materials Processing

Abstract
Laser surface carburizing can be achieved by a laser alloying mechanism, which includes melting the graphite coated substrate and dissolution of the graphite in the liquid state. The drawback of laser carburizing is that process-induced cracks frequently form on the carburized surface as a result of carbon enrichment and the..... More

Abstract
The carbon composite iron oxide briquette (CCB) is considered a potential solution to the upcoming use of low grade iron resources in the ironmaking process. CCB is able to reduce raw material cost by enabling the use of low grade powdered iron ores and coal. Additionally, the fast reduction of..... More

Smelting & Refining

Abstract
Solvent extraction experiments were performed with Re(VII) and V(V) from concentrated HCl solutions. In this work, Alamine 336 and LIX 63 were employed as the basic and cationic extractants. At an HCl concentration range from 1 to 5 M, Re(VII) was selectively extracted by Alamine 336, while V(V) was selectively..... More

Optical Devices & Energy Materials

Abstract
Cobalt silicide was used as a counter electrode to replace the Pt catalytic layer of a dye-sensitized solar cell (DSSC) device. 100 nm Si/ 100 nm Co on quartz was formed by sputtering and cobalt-silicides were formed by vacuum heat treatment at 500 ℃ and 700 ℃ for 30 min,..... More

Abstract
We investigated the effects of growth duration on the morphological, structural, and photoelectrochemical properties of TiO₂ nanorods grown on a TiO₂-buffered fluorine-doped tin oxide (FTO) substrate using the hydrothermal method. From the study, we found that the photoelectrochemical properties were mainly dependent on the nanorod length and (002) XRD peak..... More

Abstract
The objective of this study was to obtain basic data for trapping gaseous technetium (Tc) oxide generated from the voloxidation process in spent nuclear fuel pyroprocessing. Rhenium (Re) and Ca(OH)₂ were used as surrogates for the technetium and a trapping material, respectively. The trapping characteristics of rhenium oxide were investigated..... More

Modeling and Simulation

Abstract
Yttrium Aluminum Garnet (YAG) single crystal has received much attention as the high power solid-state laser’s key component in industrial and medical applications. Various growth methods have been proposed, and currently the induction-heating Czochralski (IHCZ) growth method is mainly used to grow YAG single crystal. Due to the intrinsic properties..... More

Material Analysis & Characterization

Abstract
ZnO buffer layers were deposited on mica substrates using a sol-gel spin coating method. Then, a thin film of metallic Zn was deposited onto the ZnO buffer layer/mica substrate using a thermal evaporator, and the deposited Zn thin films were then thermally oxidized in a furnace at 500 ℃ for.....

Abstract
We used Sn-58Bi and Cu wires to investigate the effects of variable conditions (such as pressure and wire diameter) on the formation of three-component nanoparticles. In the synthesis of the three-component nanoparticles, pulsed wire discharge was used to sublimate the wires. In this system, the K factor is described as..... More
