Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Spanish America in the Linguistic Landscape of Seville [PDF]

open access: yes, 2011
Las corrientes de inmigrados establecidos en España desde finales de los años 90 han convertido a muchas ciudades españolas en un entorno multilingüe. Partiendo de ese hecho y ubicándonos teóricamente dentro del amplio campo de estudio de la Lingüística ...

Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.

Constructions of Domesticity in Nineteenth-Century Spanish America [PDF]

open access: yes, 2000
It is by now a commonplace that in nineteenth-century Spanish American literature the family serves as a metaphor for the nation and that authors express their political agendas through allegories of courtship and marriage.

Evolving Platinum‐Copper Nanostructures for Enhanced Photothermal Therapy and Controlled Copper Release in Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Platinum‐Copper bimetallic nanoparticles may evolve depending on their synthesis under tumor microenvironment conditions and play a dual role as chemotherapeutic agents after releasing Cu ions and as near infrared photothermal agents with the Pt‐rich remaining frames.
