Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

Advanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Hamaker Constants of van der Waals Materials under Clean‐Interface Conditions

Advanced Science, EarlyView.
Clean‐interface adhesion in representative van der Waals materials is quantified by Ultra High Vacuum (UHV) Atomic Force Microscopy (AFM) with in situ cleaning and calibrated probes. Benchmark Hamaker constants for graphene, MoS2, and SiO2 are established, while humidity is shown to reversibly amplify adhesion, explaining much of the scatter in ...

Border harm and affective injustice: The politics of anger at the Melilla border, Spain

American Journal of Community Psychology, EarlyView.
Abstract This article examines protests in a detention center in Melilla, Spain—a site where structural violence intersects with the everyday harms of confinement. Adopting a justice and dignity‐centered perspective, we analyze grassroots forms of resistance emerging at the border. The study focuses on the protests of Tunisian migrants and explores the

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Primary scintillation yields induced by $$\alpha $$ α particles in gas mixtures of Argon/ $$\hbox {CF}_4$$ CF 4 at 9.5 bar

European Physical Journal C: Particles and Fields
We report time and band -resolved scintillation from $$\alpha $$ α -particles in Ar/ $$\hbox {CF}_4$$ CF 4 mixtures at a pressure of 9.5 bar. Our results show that %-level addition of $$\hbox {CF}_4$$ CF 4 enables strong wavelength-shifted scintillation ...

Children's food activism: Reflections on knowledge and responsibility

British Educational Research Journal, EarlyView.
Abstract Children as activists have become more prominent in recent years. Their activism is manifest in relation to conspicuously political topics such as Black Lives Matter, voting rights, being able to air their views or protesting against injustices related to race, culture and other identities. Less often, if at all, do children engage politically
