报告人简介：Ocean Cheung is an Associate Professor at the Division of Nanotechnology and Functional Materials at Uppsala University, Sweden. He holds a Master of Chemistry (MChem) degree from the University of Warwick, UK, and a PhD in Materials Chemistry from Stockholm University, Sweden. Ocean became an Associate Professor in the Department of Materials Science and Engineering at Uppsala University in 2022. He has received several prestigious awards, including the “Swedish King Gustaf’s 50th Birthday Award for Sciences, Engineering and Environment” in 2018 and the “Oscar Prize for Young Scientists” in 2020. Ocean is well recognized in the MOF field and co-hosted the 2023 Nobel Symposium on Framework Porous Materials in Sweden. In 2024, he launched a podcast series focused on MOFs called MOFCast, which has attracted listeners from over 50 countries. In 2025, he led an initiative to standardize the reporting of MOF synthesis procedures and introduced the Materials Preparation Information File (MPIF), recently reported in Advanced Materials ().
报告内容简介： In this seminar, we will discuss our approach to the development of functional solid materials for capturing greenhouse gases and other applications. The presentation is divided into two sections: Nanoporous materials such as zeolites and metal-organic frameworks (MOFs) are highly tailorable. Their structural diversity and tunability allow us to fine-tune these materials for the selective sorption of different gases. Pore size tuning, in particular, is an effective strategy for designing sorbents with very high selectivity for greenhouse gases such as SF₆ and CO₂. Depending on the target gas, different approaches to pore size tuning are required to achieve optimal sorption properties. Examples of pore size tuning in zeolites (NaKA) and MOFs (ZIF-7-8, UU-200-204, and KAUST-7) will be presented. Novel approaches to utilizing solid physisorbents for CO₂ capture will also be discussed. In addition to greenhouse gas capture, we will discuss the development and application of mesoporous magnesium carbonate for drug delivery. These mesoporous carbonates possess unique structural properties that make them promising carrier materials for poorly soluble active pharmaceutical ingredients (APIs). Their high specific surface area enables surface functionalization. By combining pore size control with surface functionalization, both API loading and release properties can be tailored. Beyond drug loading and delivery, these inorganic carbonates can also function as sorbents for azo dyes and CO₂. Finally, mesoporous inorganic carbonates can serve as templates for the synthesis of other functional porous materials, such as highly porous amorphous calcium phosphate and porous carbon. |
