Abstract
The combination of severe plastic deformation, deformational heat, and frictional heat generated during the high-pressure torsion process has a great effect on microstructural evolutions, including grain refinement, dynamic recrystallization and recovery. In particular, the low melting temperature metallic alloys (e.g., aluminum and magnesium) also induce nano-precipitations in the matrix during..... More

Abstract
Stainless steel-based composites (SMCs) mixed with 316L stainless steel powder and Fe-Cr-B based M alloys powder ed M) powder were manufactured using the powder injection molding (PIM) process, and their microstructure and mechanical properties were investigated. To examine the effect of M content on the properties of SMCs, the M..... More

Abstract
The main components of molding sand used in sand casting are sand, clay and water. The composition of the molding sand has a great influence on the properties of the casting. In order to obtain high-quality castings, it is important to manage the components that affect the properties of the..... More

Abstract
Nowadays, high-density electronic devices and component mounting have gained popularity. Because of the heat generated from these devices, efficiency of the electronic parts is significantly lowered and life time of these devices is considerably shortened. Therefore, it is very important to efficiently dissipate the heat generated from the device to..... More

Abstract
Colloidal quantum dots (QDs) have attractive optical and electrical characteristics for various applications in the display industry. They have superb properties including color tunability, which is achieved by controlling the particle size and solution processes used for quantum dot light-emitting diodes (QLEDs). Here we demonstrate high efficiency QLEDs that consist..... More

Abstract
One of the most popular routes used to improve the thermoelectric performance of materials is to suppress their lattice thermal conductivities. Thermoelectric performance is characterized by a figure-of-merit zT, which is defined as σS²T/(κ_e + κ_l), where the σ, S, T, κ_e, and κ_l are the electrical conductivity, Seebeck coefficient,.....

Abstract
In this study, Cu₃Sb_1-ySn_ySe₄ (0 ≤ y ≤ 0.08) permingeatites were synthesized via mechanical alloying followed by hot pressing. The phase transformation, microstructure, charge transport parameters of the permingeatites, and their thermoelectric properties were analyzed. The permingeatites were present in a single phase with a tetragonal structure, and secondary phases..... More

Abstract
Despite the recent advances in nature-inspired superhydrophobic surfaces with multifunctional properties such as self-healing, self-cleaning, antibacterial material, anti-biofouling, and oil-water separation in various industrial applications, there have been very few reports of robust superhydrophobic surfaces fabricated via a low-cost method. Herein, we report a rationally designed, self-healable, robust, and superhydrophobic..... More

Abstract
Macrostructural features in continuously-cast stainless steel slabs such as the distribution of equiaxed and columnar grains, and microporosity, are crucial to the post-processes, and the mechanical properties of the final steel products. Among the methods for controlling grain structure during the continuous casting process, the application of electromagnetic stirring (EMS)..... More
