| 3 | Nanoparticle Exsolution on Perovskite Oxides:Insights into Mechanism,Characteristics and Novel Strategies显示文摘Supported nanoparticles have attracted considerable attention as a promising catalyst for achieving unique properties in numerous applications,including fuel cells,chemical conversion,and batteries.Nanocatalysts demonstrate high activity by expanding the number of active sites,but they also intensify deactivation issues,such as agglomeration and poisoning,simultaneously.Exsolution for bottomup synthesis of supported nanoparticles has emerged as a breakthrough technique to overcome limitations associated with conventional nanomaterials.Nanoparticles are uniformly exsolved from perovskite oxide supports and socketed into the oxide support by a one-step reduction process.Their uniformity and stability,resulting from the socketed structure,play a crucial role in the development of novel nanocatalysts.Recently,tremendous research efforts have been dedicated to further controlling exsolution particles.To effectively address exsolution at a more precise level,understanding the underlying mechanism is essential.This review presents a comprehensive overview of the exsolution mechanism,with a focus on its driving force,processes,properties,and synergetic strategies,as well as new pathways for optimizing nanocatalysts in diverse applications. | Yo Han Kim Hyeongwon Jeong Bo‑Ram Won Hyejin Jeon Chan‑ho Park Dayoung Park Yeeun Kim Somi Lee Jae‑ha Myung | 2024 | Nano-Micro Letters2024，16，2： | 0 |
| 5 | Step-growth polymerization of traptavidin-DNA conjugates for plasmonic nanostructures显示文摘Here,we use two important biomaterials,protein and DNA,to construct self-assembled linear nanostructures through Watson-Crick base-paring of DNAs.We apply a simple magnetic separation method to purify traptavidin-DNA co njugates,and demonstrate synthesis of linear arrays of traptavidinDNA conjugates via the step-growth polymerization approach with pre-determined DNA sequences.Using the traptavidin-DNA array as a template,we assemble gold nanoparticles to form linear plasmonic nanostructures in a programmable manner.The traptavidin-DNA conjugates thus provide a convenient platform for one-dimensional assembly of biotinylated nanomaterials for many biomedical applications from drug delivery to bio-sensing. | Young-Youb Kim Yongbin Bang Dayoung Lee Mingyu Kang Yoon-Kyu Song | 2020 | Chinese Chemical Letters2020，31，5： | 0 |
