Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

open access: yesAdvanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Consumer Health Perceptions of Cows' Milk and Plant‐Based Milk Alternatives

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study used a best‐worst scale experiment to reveal consumers' beliefs about the healthiness of selected cows' milk and plant‐based milk products based on their nutrition panels. We find that while there is heterogeneity in health perceptions, consumers overwhelmingly select skim milk as the healthiest milk product. Additionally, the cows'
