Advanced Materials Interfaces, EarlyView.ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...

Mitigating policies for pollutant emissions in a DSGE for the Brazilian economy
Latin American Journal of Central BankingThis paper examines the dynamic behavior of the Brazilian economy under policy regimes aimed at controlling pollutant emissions and limiting environmental damage. Greenhouse gas (GHG) emissions are assumed to be of two types: carbon from fossil resources

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites
Advanced Materials Technologies, EarlyView.Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Conservadorismo e independência no Banco Central do Brasil
Revista Economia & Tecnologia, 2011 O Banco Central do Brasil é sistematicamente criticado por suas decisões sobre a taxa básica de juros (SELIC), acusado de ser excessivamente preocupado ou muito leniente com a inflação. Caso o Banco Central estivesse tendo um viés sistemático em suas decisões, a taxa de inflação deveria estar muito mais alta ou muito mais baixa do que a observada, a ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
