Anti‐Globalization Dynamics and Africa's Structural Transformation: Identifying Avoidable Environmental Degradation Thresholds

open access: yesSustainable Development, EarlyView.
ABSTRACT This study pursues a dual objective. First, it investigates the unconditional impact of anti‐globalization on structural transformation in Africa. Second, it explores how environmental degradation interacts with anti‐globalization to influence structural transformation. The analysis focuses on 52 African countries over the period 2005–2023. To

Reorientation‐Driven Degradation in Oriented Perovskite Films: Shifting Facet Engineering to Thermodynamic Stability

open access: yesSmall, EarlyView.
The role of crystallographic orientation in the thermal stability of narrow‐bandgap perovskite solar cells remains largely underexplored. In Sn–Pb mixed perovskite films, strong orientation can inherently compromise stability under prolonged thermal stress, triggering reorientation‐induced degradation through microstrain accumulation.

Local Activity and Selectivity Hotspots in Cu‐Pt Model Thin‐Film Electrocatalysts for Oxygen Reduction

open access: yesSmall Methods, EarlyView.
A Cu‐Pt model thin film catalyst is investigated via electrochemical scanning tunneling microscopy. This technique enables in‐operando active site detection on a nanometer scale. It is shown that the precise location of the active sites changes depending on the selectivity of the oxygen reduction reaction.

Na4Ba9MnN3: A New Subnitridometalate with Trigonal Planar Anions [MnIIIN3]6−

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new subvalent nitridomanganate(III) Na4Ba9MnN3 contains structural elements known from ionic subnitridometalates as well as from intermetallic phases. In similarity to Ba3MnN3, isolated trigonal planar nitridomanganate(III) anions (MnN3)6−, coordinated by barium atoms represent the ionic region, while mixed barium‐sodium icosahedra known from ...

The performance of growing degree day models to predict spring phenology of herbaceous species depends on the species' temporal niche

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally to the accumulated temperature. Two species‐specific parameters, TBase and t0 (minimum temperature above which and start date

Measuring the time‐varying market efficiency in the prewar and wartime Japanese stock market, 1924–1943

open access: yesAsia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.
Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.
