COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption

open access: yesAdvanced Materials, EarlyView.
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This

Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

open access: yesOikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Spatially Resolved Strain Mapping In Flexible Oxide Membranes

open access: yesSmall, EarlyView.
High‐resolution synchrotron x‐ray diffraction reveals how strain transfers and distributes within crystalline oriented oxide membranes (10–100 nm thick) on flexible substrates that are subjected to stretching and bending. The study uncovers local strain heterogeneities that deviate from macroscopic averages, providing a crucial framework when ...

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

open access: yesWildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

The Edification of Manuela Xiqués: Slavery, Finance, Biography, and the Construction of Modern Barcelona

open access: yesGender &History, EarlyView.
ABSTRACT An analysis of the dual biographies, economic and domestic, of Manuela Xiqués, an enslaver from nineteenth‐century Cuba and Spain, deepens our understanding of the role of European and Creole women in the nineteenth‐century Atlantic. This essay foregrounds the role of literature, namely family biography, as a locus of the processes of ...

Framings of Intervention in Spain: From the Civil War to the Franco Dictatorship

open access: yesHistory, EarlyView.
Abstract Despite the role of foreign intervention in the Spanish Civil War, the word intervención rarely appeared in contemporary media and official discourse. This article examines the expressions that Republican and rebel authorities used to represent the presence of outside forces in Spain.
