Abstract
This study investigated the removal of the organic dye like methylene blue using porous particles in a batch adsorption process. Porous silica microparticles were synthesized with macropores or meso-macropores and used as adsorbent particles. The hierarchically porous structures with additional mesopores were found to be more effective adsorbent than simple.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.12.910
Abstract
Since catalyst technology is one of the promising technologies to improve the working performance of next generation energy and electronic devices, many efforts have been made to develop various catalysts with high efficiency at a low cost. However, there are remaining challenges to be resolved in order to use the.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.9.658
Abstract
Titanium nitride (TiN) has been used extensively in coating materials and cutting tools because of its attractive properties, which include low density, high melting point, high hardness and thermodynamic stability. However, like many ceramic materials, its low fracture toughness limits wide industrial application. The methods generally utilized to improve its.....

https://doi.org/10.3365/KJMM.2016.54.12.893
Abstract
The low mechanical properties of SiC limit its wide application despite many attractive properties. To improve the mechanical properties, a second phase has been generally added to make a nanostructured composite. In this respect, graphene was evaluated as the reinforcing agent of SiC. SiC-graphene composites were sintered within 2 min.....

DOI:
https://doi.org/10.3365/KJMM.2016.54.9.711
Abstract
Micro-twinning has been investigated in some state-of-the-art materials by transmission electron microscopy, but such characterizations have not been clear so far. Micro-twins must be characterized by identifying their spots in the electron diffraction pattern, which is very unique compared to normal defects such as dislocations or stacking.....
