Advanced Functional Materials, EarlyView.This study demonstrates a molecular strategy to enhance the stretchability of conjugated polymers by incorporating plasticizing molecular additives (PMAs). PMAs reduce the persistence length and promote chain entanglement, enabling deformable thin films with preserved electrical performance. A systematic analysis combining rheology, neutron scattering,

Permeation Enhancer‐based Ionogel Shows Remarkable Potential for Oral Insulin Delivery
Advanced Healthcare Materials, EarlyView.This study proposes a novel formulation of decanoate in an ionic liquid inspired drug delivery system. The formulation demonstrates ideal physicochemical and material properties for oral peptide delivery. Findings indicate that choline decanoate (1:2 molar ratio) forms a viscoelastic gel that enables high oral bioavailability of insulin in rats ...

Acoustic Moiré Flat Bands in Twisted Heterobilayer Metasurface
Advanced Materials, EarlyView.This research proposes a heterobilayer moiré acoustic metasurface using two distinct lattice structures. The heterobilayer design contributes to divergent dispersion curves for the upper and lower layers and allows for greater flexibility in tuning their hybridization through interlayer twisting.

On the definition of ellipticity for systems of partial differential equations
Journal of Mathematical Analysis and Applications, 1991 One of the fundamental problems in the theory of partial differential equations is that of classifying equations and systems by type. A specific problem associated with the definition of ellipticity is that when a higherorder equation or system is reduced to a first order system, ellipticity may be destroyed. One approach to that problem was introduced

Advanced Materials, EarlyView.This work investigates Ruddlesden–Popper (RP) defects in vapor‐deposited CsPbI3 thin films using electron microscopy, density functional theory, and optoelectronic measurements. The atomic positions at the planar defect are found comparable to those of a free surface, revealing their role in phase stabilization.
