Lewis Acid-Catalyzed Ring-Opening Alcoholysis of Cyclohexene Oxide : The Role of Open Metal Sites in the Bi(III)-based Metal-Organic Framework SU-101

Journal article (peer-reviewed)abstract
- SU-101 was screened for the acid-catalyzed ring-opening alcoholysis of cyclohexene oxide. Results indicated access to open metal sites within SU-101, a fundamental requirement (Lewis acid Bi+3 sites) for this reaction. In addition, SU-101 exhibited high chemical stability, demonstrated by retaining its crystalline structure after the reaction. The cyclohexene conversion was estimated to be 99.8, 96.8, and 14.3 % at 40 °C for methanol, ethanol, and propanol, respectively. Also, SU-101 demonstrated an outstanding catalytic cyclability performance for five cycles without losing catalytic activity.

- Sustainability requires a combination of meaningful co-production of locally relevant solutions, synthesis of insights gained across regions, and increased cooperation between science, policy and practice. The Programme for Ecosystem Change and Society (PECS) has been coordinating Place-Based Social-Ecological Sustainability Research (PBSESR) across the globe and emphasizes the need for regional scientific nodes from diverse biocultural regions to inform sustainability science and action. In this paper, we assess the strengths of the PBSESR communities in Latin America and the Caribbean (LAC). We provide an overview of PBSESR literature associated with this region and highlight the achievements of two prominent regional networks: The Social-Ecological Systems and Sustainability Research Network from Mexico (SocioEcoS) and the South American Institute for Resilience and Sustainability Studies from Uruguay (SARAS Institute). Finally, we identify the potential in these nodes to constitute a regional PECS node in Latin America and discuss the capacity needed to ensure such function. The results of the literature review show that while still loosely interconnected across the region, networks play key roles in connecting otherwise cloistered teams and we illustrate how the SocioEcoS network (focusing on transdisciplinary co-production of knowledge towards sustainability) and the SARAS Institute (focusing on innovative approaches for looking at complex social-ecological problems, rooted in slow science and arts) operate as key connectors in the region. We conclude that these organizations combined can embody a Latin American node for PECS, and would thereby not only contribute to regional but also global capacities to advance the sustainability agenda.

Encapsulation of dopamine within SU-101 : insights by computational chemistry
- 2023
-
In: Chemical Communications. - 1359-7345 .- 1364-548X. ; 59:56, s. 8684-8687

Journal article (peer-reviewed)abstract
- Encapsulating and protecting dopamine from oxidation is a difficult challenge. We propose to use SU-101 BioMOF as a dopamine host, where we study different adsorption scenarios by a robust computational approach. Our results show that dopamine encapsulation is feasible with the formation of non-covalent interactions within the SU-101 pores. These computational results have been corroborated experimentally.
