DOI:
https://doi.org/10.3365/KJMM.2019.57.1.38
Abstract
Many important material properties of ferroelectric ceramics such as piezoelectric coefficient and hysteresis curve are governed by domain structures and their evolution processes. In the present work, domain wall motions in a near-morphotropic Pb(Zr,Ti)O3 under an external compressive stress were observed using in situ piezoresponse force microscopy (PFM). This specific.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.10.718
Abstract
In this work, we studied the formation of partially stabilized zirconia by a high energy ball milling (HEBM) approach. Zirconia powder was mixed with 8 mol% MgO and the powder mixture was milled for 10 hours. The structural and morphological evolutions of the powder particles were studied using X-ray diffraction.....

Abstract
Industrially meaningful hydrogen production process from mixture or syngas certainly must have a cooling process, which is typically pressure swing adsorption (PSA). However, the PSA process involves an exothermic reaction during adsorption. Recently, hydrogen separation research has been in progress in order to develop a cooling process to minimize or.....

Abstract
Vacuum kinetic spraying (VKS) is a relatively advanced process, by which a dense film can be fabricated at room temperature. Various materials including ceramic, metal, polymer and composite can be used as the substrate and coating materials. In this research, red and blue color films were successfully fabricated on glass.....
