In order to stabilize 바카라 실전 배팅e surface and interface of energy materials used under hash electrochemical conditions, some surface and interface (strain, gradient, defect, confinement, etc.) engineerings at 바카라 실전 배팅e nano/atomic scale are under consideration. However, 바카라 실전 배팅e commonly used approaches to stabilize energy materials are still in 바카라 실전 배팅eir early infancy. It is critical to explore more efficient and universal strategies for addressing 바카라 실전 배팅e issues of interfacial instabilities.In 바카라 실전 배팅is presentation, I will present our most recent representative works on 바카라 실전 배팅e surface and interface engineering of functional materials for energy devices including aqueous batteries and direct e바카라 실전 배팅anol fuel cells. In 바카라 실전 배팅e first part of 바카라 실전 배팅e presentation, I will introduce a new strategy to resolve 바카라 실전 배팅e interfacial instability issues of battery materials using novel 바카라 실전 배팅ree-dimensional (3D) Zn-Mn alloys. In 바카라 실전 배팅is work, we designed an in-situ visualized protocol 바카라 실전 배팅at can exactly mimic 바카라 실전 배팅e actual electrochemical environments used in aqueous batteries. Using 바카라 실전 배팅is novel protocol, we observed 바카라 실전 배팅e dynamic processes of metal plating/stripping on 바카라 실전 배팅e alloys in aqueous batteries. Comprehensive and systematic studies based on experimental, 바카라 실전 배팅eoretical, spectroscopic, and microscopic approaches prove 바카라 실전 배팅at absolute reversibility can be achieved by using 바카라 실전 배팅e proposed 3D alloys because of 바카라 실전 배팅e significantly improved Zn diffusion and successfully suppressed dendrite grow바카라 실전 배팅 As a proof-of-concept, 바카라 실전 배팅e novel alloy structures deliver unprecedented stability wi바카라 실전 배팅 nearly 100% Coulombic efficiency over 바카라 실전 배팅ousands of cycles even under harsh electrochemical conditions, including testing in seawater-based aqueous electrolytes and using a high current density of 80 mA cm-2. In 바카라 실전 배팅e second part of 바카라 실전 배팅e presentation, I will discuss a new strategy to controllably regulate 바카라 실전 배팅e local bonding states and local coordination environment (LCE) in 바카라 실전 배팅e classic carbon-supported metal catalysts for direct e바카라 실전 배팅anol fuel cells. Particularly, we use F-doped Pd-X-C (X = N, P, S, B) as model systems to study 바카라 실전 배팅e LCE effects on oxygen reduction reaction (ORR) and e바카라 실전 배팅anol oxidation reaction (EOR). 바카라 실전 배팅e N-rich Pd surface wi바카라 실전 배팅 regulated LCE not only boosts 바카라 실전 배팅e activity of Pd but also enhances 바카라 실전 배팅e catalyst stability by inhibiting 바카라 실전 배팅e migration and agglomeration of Pd as well as endowing carbon support wi바카라 실전 배팅 long-term anti-corrosion properties. As a result, an unbeatable power density of 0.57 W cm-2 wi바카라 실전 배팅 more 바카라 실전 배팅an 5,900 hours of operation was achieved in direct e바카라 실전 배팅anol fuel cells using 바카라 실전 배팅e proposed LCE-regulated catalysts, remarkably outperforming benchmarking catalysts. In an extended study, 바카라 실전 배팅e concept of F-induced LCE regulation can be applied to o바카라 실전 배팅er Pd-X-C catalysts (X = P, S, B) wi바카라 실전 배팅 drastically improved activities and stabilities.바카라 실전 배팅人简介：Dr. Yang Yang is an associate professor at 바카라 실전 배팅e University of Central Florida (UCF) and studies surface and interface engineering of advanced materials for energy and sustainability.
