MgO 나노선의 성장과 음극선 발광 특성에 미치는 산소 농도의 영향
Geun-Hyoung Lee
Korean J. Met. Mater. 2023;61(7):509-513.   Published online 2023 Jun 21
DOI: https://doi.org/10.3365/KJMM.2023.61.7.509

MgO nanowires were grown by a thermal evaporation method at different N2/O2 gas ratios in order to investigate the effect of oxygen concentration on the growth and luminescence properties of the MgO nanowires. A thermal evaporation process was conducted at 1000oC and under a pressure of 500Torr. No nanowires were..... More

Branched MgO Nanowires Synthesized by Thermal Evaporation Method in Air at Atmospheric Pressure
대기압의 공기 분위기에서 열증발법에 의해 합성된 가지상 구조의 MgO 나노선

Korean J. Met. Mater. 2023;61(6):444-448.   Published online 2023 May 18
DOI: https://doi.org/10.3365/KJMM.2023.61.6.444

MgO nanowires with a branched structure were fabricated using a thermal evaporation method in air at atmospheric pressure. The branched MgO nanowire was made up of two parts: a primary central nanowire trunk and lots of secondary nanowire branches. The branched MgO nanowires had a 4-fold symmetrical structure. The secondary..... More

Ultrathin MgO Nanosheets Fabricated by Thermal Evaporation Method in Air at Atmospheric Pressure
대기압의 공기 분위기에서 열증발법에 의해 제작된 초박형 MgO 나노시트
Geun-Hyoung Lee
Korean J. Met. Mater. 2022;60(10):769-773.   Published online 2022 Sep 29
DOI: https://doi.org/10.3365/KJMM.2022.60.10.769

Ultrathin MgO nanosheets were successfully synthesized by thermal evaporation of a mixture of Mg and graphite powders as the source material. The synthesis was performed at 1000 oC in air. Scanning electron microscopy showed that the two-dimensional MgO nanosheets had widths of several micrometers and the thickness of less than..... More

Korean J. Met. Mater. 2021;59(6):392-403.   Published online 2021 May 26
DOI: https://doi.org/10.3365/KJMM.2021.59.6.392

A novel magnesium (Mg) production process utilizing an electrolytic method was investigated for the direct reduction of magnesium oxide (MgO). Electrolysis of MgO was carried out with an applied voltage of 3.0 V using a copper (Cu), silver (Ag), or tin (Sn) cathode and carbon (C) or platinum (Pt) anode..... More
