On the effective action for scalars in a general manifold to any loop order

open access: yesPhysics Letters B, 2023
Functional methods and a derivative expansion are employed for laying out a procedure to compute the effective action to any loop order, for scalar fields parametrising an arbitrary Riemannian manifold, while maintaining explicit field-space covariance ...

High‐Yield Bioproduction of Extracellular Vesicles from Stem Cell Spheroids via Millifluidic Vortex Transport

open access: yesAdvanced Materials, EarlyView.
Stem cell spheroids, produced via a high‐throughput microfabrication technique, are transported within a vortex generated at the outlet channels of a cross‐slot millifluidic chip. For Reynolds number exceeding 170–200, intermittent high shear stresses applied to each spheroid within the vortex trigger a massive release of biologically active ...

Epitaxial Ferroelectric Hexagonal Boron Nitride Grown on Graphene

open access: yesAdvanced Materials, EarlyView.
The epitaxial growth of hexagonal boron nitride (h‐BN) multilayer films on graphene, synthesized on a miscut SiC (0001) substrate, is demonstrated using nitrogen plasma‐assisted molecular‐beam epitaxy. Robust ferroelectricity with switchable out‐of‐plane polarization via interlayer sliding is supported by theoretical and experimental insights ...
