Abstract
The effect of freezing conditions on the pore structure of porous TiO₂ fabricated using a freeze casting process with tert-butyl alcohol slurry was investigated. The raw powder was heat treated to manufacture a porous body with stable shape by suppressing volume change induced by the phase transformation of TiO₂ powder...... More

Abstract
Direct Energy Deposition (DED) is one of the main methods of additive manufacturing in which a feedstock material in the form of powder or wire is delivered to a substrate while an energy source, such as laser beam or electron beam, is simultaneously applied to melt the feedstock. In addition..... More

Abstract
As environmental pollution has intensified, the importance of recycling spent lithium-ion batteries (LIBs) has significantly increased. Valuable metals contained in LIBs are typically recovered through processes such as leaching, precipitation, and solvent extraction. However, these recycling processes require large amounts of sulfuric acid and caustic soda, resulting in the generation..... More

Abstract
To determine the effect of Polyethylene Glycol(PEG) and Chloride ions(Cl-) as additives during electroplating, this study used interaction plots of various characteristics of the electroplated Cu foils for analyses. Crystals of about 2 µm in size were observed on the surface of Cu electroplated in the electrolyte without PEG. When..... More

Abstract
Hydrogen sulfide (H₂S) is a highly toxic and dangerous gas with a flammable and corrosive nature, making the development of reliable gas sensors for its detection vital. This study investigated the enhancement in H₂S gas sensing performance of commercial SnO₂ powders after high-energy milling. SnO₂ powders were subjected to high-energy..... More

Abstract
This study investigates the thermoelectric properties of Fe_1-xCo_xSe₂ (x = 0, 0.25, 0.5, 0.75, and 1) alloys using theoretical modeling approaches. The Single Parabolic Band (SPB) model was employed to calculate band parameters such as density-of-states effective mass (m_d*), non-degenerate mobility (μ₀), weighted mobility (μ_w), and B-factor. As the alloying..... More

Abstract
Carbon materials used as an electrode for aqueous supercapacitors should be synthesized with a porous structure and hydrophilic properties to facilitate the adsorption and desorption of electrolyte ions for charge storage. To enlarge the specific surface area, the porous morphology should contain micropores (diameter < 2 nm). Mesopores (diameter: 2..... More

Abstract
Since the recently reported biotoxicity of Ni, the use of Ti-Ni base shape memory alloys as biomaterial has been reduced. For this reason, Ti–Nb base superelastic alloys consisting of only non-toxic elements are being actively studied for potential use as biomaterials. In this study, the effects of Zr content and.....

Abstract
The purpose of this study is to analyze the components and observe the microstructure of 98 bronze vessels excavated from the Korean Peninsula, where such vessels were widely used, to identify the alloy composition and manufacturing process of bronze artifacts by period. In addition, we attempted to confirm the changing..... More
