Advanced Science, EarlyView.Purposive doping of low electronegative Ba2+ (0.89) at La3+ (1.1) site in LaFe0.7Ni0.3O3‐δ induces the formation of a tri‐phase composite, which shortens Fe─O bond and lowers activation energy, thereby significantly improves electrical conductivity and catalytic activity, and finally offers a record‐high peak power density in La0.5Ba0.5Fe0.7Ni0.3O3‐δ ...

Giulio II: da 'papa Guerriero' a 'papa Penitente'
Incontri. Rivista europea di studi italiani, 2017 Julius II from ‘Warrior Pope’ to ‘Penitent Pope’This article discusses the commission and meaning of the tomb monument of Pope Julius II (1503-1513), with a focus on the statue representing the pope himself. In 1505, when Julius II ordered Michelangelo to make this monument, it was quite uncommon that a pope would commission his own tomb, as this was ...

"Goldilocks and the Three Bears" [PDF]
Unlike the Papa, Mama, and Baby Bears faced by the storybook Goldilocks, our Goldilocks faced three ferocious grizzlies: a cascading, global financial crisis; global deflation and excess capacity (or insufficient demand); and a domestic fiscal surplus in

Spontaneous Perovskite Passivator Featuring Dual Functional Groups
Advanced Energy Materials, EarlyView.A novel strategy to suppress multiple defect sites in perovskite crystals using a spontaneous passivator with dual functional groups is proposed, addressing an intrinsic drawback of conventional spontaneous perovskite passivators. 2‐thiophene‐ethyl‐ammonium‐bis(trifluoromethylsulfonyl)imide (TEA‐TFSI) is newly synthesized and successfully demonstrate ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells
Advanced 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 ...

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We link American Community Survey and SNAP records for 185,000 units with ground‐sourced social food infrastructure data from FindFoodIL (Illinois Extension SNAP‐Ed) to examine SNAP participation determinants among eligible units. Bivariate probit models reveal, beyond SNAP offices, quantity of social infrastructure is associated with ...
