Three Birds with One Stone: High‐Performance 2D Lead‐Free Perovskite Solar Cells via Direct In Situ Generation of Organic‐Spacer Precursors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Adopting a “three birds with one stone” strategy, the in situ generation of organic spacer simultaneously addresses three major challenges limiting 2D tin‐based perovskites: (1) Sn2+ oxidation; (2) rapid crystallization; and (3) uncontrolled 2D phase distribution.

Rational A‐Site Multi‐Cation Design Enables Durable Fe‐Based Perovskite Air Electrodes for Fast Oxygen Reduction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A‐site multi‐cation doping in Pr0.5Ba0.5FeO3−δ produces Pr1/6La1/6Nd1/6Ba1/6Sr1/6Ca1/6FeO3−δ with reduced size mismatch and charge‐transfer energy, showing the highest electrocatalytic activity among those of Pr0.5Ba0.5FeO3−δ. Although Pr0.5Ba0.5FeO3–δ (PBF)‐based perovskite cathodes are prevalent for solid oxide fuel cells (SOFCs), their practical ...

Soil Carbon Markets in the Making: Power Relations and Matters of Concern in Offsetting and Insetting

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT This paper investigates emerging soil carbon markets and seeks to identify the groups of actors and power relations that constitute their structure and function. Voluntary soil carbon markets (VSCMs) are emerging globally as a key mechanism for generating carbon removals as part of climate mitigation efforts.

Euromaidan and Ukrainian Subjective Well‐Being

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT The 2013–2014 Euromaidan in Ukraine was the largest series of pro‐European protests in history. Peaceful civilian protests were met with state violence, resulting in widespread civil unrest, over 100 deaths, and nearly 2000 injuries. The Russo‐Ukrainian War broke out shortly after. We examined the immediate and long‐term changes in Ukrainians’
