Controlled optimization of Mg and Zn in Al alloys for improved corrosion resistance via uniform corrosion

Autor: Jaehyoung Lim, Geonwoo Jeong, Kookjeong Seo, Jungsoo Lim, Sangjun Park, Won Ju, Gnanaprakasam Janani, Dong-Kyu Lee, Joon Young Kim, Mi-Kyung Han, Tae-Hoon Kim, Sungtae Park, Hoonsung Cho, Uk Sim

Publikováno v: Materials Advances. 3:4813-4823

The inclusion of trace amounts of Mg and Zn to Al alloys caused the development of β and τ phases at the grain boundary, resulting in the change from pitting corrosion to intergranular corrosion and therefore increased corrosion resistance.

Boosting eco-friendly hydrogen generation by urea-assisted water electrolysis using spinel M2GeO4(M = Fe, Co) as an active electrocatalyst

Autor: Subramani Surendran, Yoongu Lim, Uk Sim, Jaehyoung Lim, Hyeonuk Choi, Mi-Kyung Han, Jihyun Park, Jung Kyu Kim, Dohun Kim

Publikováno v: Environmental Science: Nano. 8:3110-3121

To enhance the efficiency of hydrogen production, bimetallic oxides with spinel structures, M2GeO4 (M = Fe, Co), were synthesized via a facile one-pot hydrothermal method and were used as electrocatalysts for urea-assisted water electrolysis. In alka
