Professor Man-Sung Yim's research lab focuses on advanced materials and sustainable energy technologies, with a strong emphasis on nuclear energy safety, environmental remediation, and clean energy systems. Key research directions include the development of novel adsorbents—such as bismuth-based metal-organic frameworks (MOFs) and activated carbon composites—for capturing radioactive iodine and uranium from seawater, particularly under extreme conditions like severe nuclear accidents. The lab also investigates the integration of renewable energy into national grids, addressing challenges related to excess electricity generation and grid stability through innovative modeling and management strategies. Additionally, the lab explores public perception and socio-technical factors influencing nuclear energy adoption, combining materials science with policy-relevant research.

To support the use of nuclear power as a sustainable electric energy generating technology, long-term supply of uranium is very important. The objective of this research is to investigate the use of new adsorbent material for cost effective uranium extraction from seawater. An activated carbon-based adsorbent material is developed and tested through an electrosorption technique in this research. Adsorption of uranium from seawater by activated carbon electrodes was investigated through electroso
Public acceptance is a major issue that will determine the future of nuclear energy. In this article, we review relevant studies and identify several common patterns of nuclear public acceptance. Based on these patterns and four categories of factors, we propose hypotheses on the impact of different socioeconomic factors on the public opinion of nuclear energy. These factors were demographic and social influences, politico-economic, energy conditions, and nuclear accidents and natural risks. We
In this study, a bismuth-based metal–organic framework (Bi-MOF) was investigated in its applicability as an iodine adsorbent at high temperatures for possible applications under severe accidents in a nuclear power plant. Bi-mna was selected among Bi-MOF candidates based on its thermodynamic characteristics, which expected to allow chemisorption of iodine by bismuth. Its iodine adsorption performance was compared with zeolitic imidazolate framework-8 and Cu-BTC and other MOFs which were chosen du
The purpose of this study is to examine the feasibility of using bismuth-embedded SBA-15 (Bi-SBA-15) as gaseous iodine filtration material for applications at higher temperatures, such as environmental release severe accident mitigation, while reducing the cost of production and maintaining its iodine adsorption capacity. It was shown that Bi-SBA-15 can be produced in a much more economically feasible way by (1) increasing the amount of the chemical reagents for SBA-15 synthesis, (2) decreasing
