Controlling Moisture for Enhanced Ozone Decomposition: A Study of Water Effects on CeO$_2$ Surfaces and Catalytic Activity

Autor: Gupta, Suchitra, Choi, Joon Hwan, Jeong, Hojin, Lee, Seung-Cheol, Bhattacharjee, Satadeep

This study investigates the catalytic degradation of ground-level ozone on low-index stoichiometric and reduced CeO$_2$ surfaces using first-principles calculations. The presence of oxygen vacancies on the surface enhances the interaction between ozo

Autor: Seung-Hee Ryu, Seungeun Kim, Hyunjoo Lee, Joon-Hwan Choi, Hojin Jeong

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-15 (2024)

Abstract Optimizing metal catalyst structures to achieve desired states is vital for efficient surface reactions, yet remains challenging due to the lack of well-defined precursor materials and weak metal-support interaction. Palladium-based catalyst

Association of executive function with suicidality based on resting-state functional connectivity in young adults with subthreshold depression

Autor: Je-Yeon Yun, Soo-Hee Choi, Susan Park, Joon Hwan Jang

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-14 (2023)

Abstract Subthreshold depression (StD) is associated an increased risk of developing major depressive disorder (MDD) and suicidality. Suicidality could be linked to distress intolerance and use of context-dependent strategies. We identified neural co
