Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study
Advanced Functional Materials, EarlyView.This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Aggregate Savings in the Presence of Private and Social Insurance [PDF]
In the presence of uncertain lifetimes, social security has the characteristics of an annuity: a consumer pays a tax when young in exchange for receiving a social security benefit if he survives to be old.

Charge‐Induced Morphing Gels for Bioinspired Actuation
Advanced Functional Materials, EarlyView.This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Social Security in Germany: A Prey of Political Opportunism? [PDF]
This paper examines how politicians influenced social security policy in Germany. Using yearly data from the German Pension Insurance from 1957 to 2005, revenues as well as expenditures are analysed in linear regression models, respectively.

Advanced Functional Materials, EarlyView.High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.

Towards Social Security Systems in Japan Lessons for India [PDF]
Japan has to restructure its social security systems fromtime to time for different reasons like a far more rapid aging of population , the slow down of long term economic growth and deteriorating equity in the inter-generational transfer of welfare .But

Advanced Functional Materials, EarlyView.This work presents a continuous linear gradient catalyst layer design, a general strategy for improving membrane electrode assemblies across electrochemical devices. Fabricated via a dual‐nozzle spray coating method, the architecture controls the Pt/carbon ratio, ionomer content and ionomer type across the catalyst layer, enhancing proton conduction ...
