Cu2O/Cu Chiral Catalysts for Highly Selective Solar‐Assisted CO2‐to‐CO Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
To address the poor target‐product selectivity of the eCO2RR, breakthrough approaches based on the chiral‐induced spin selectivity phenomenon enhance the Faradaic efficiency (FE) for target hydrocarbons, such as CO. To induce this spin polarization strategy in Cu2O/Cu catalysts, it is proposed using amine‐based intermediate organic molecules with ...

Non-invertible symmetry in Calabi-Yau conformal field theories

open access: yesJournal of High Energy Physics
We construct examples of non-invertible global symmetries in two-dimensional superconformal field theories described by sigma models into Calabi-Yau target spaces.

Aerosol Jet Printed MXene Microsupercapacitors for Flexible and Washable Textile Energy Storage

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel approach using aerosol jet printing to fabricate e‐textiles with additive‐free aqueous Ti3C2Tx MXene inks. The flexible electrodes, systematically explored on cotton, polycotton, and polyester, exhibit remarkable areal capacitances of up to 4.4 F cm−2, achieving superior high‐rate performance, capacitance retention, and ...

Six-dimensional correlators from a five-dimensional operator product expansion

open access: yesJournal of High Energy Physics
In this letter we discuss the operator product expansion of scalar operators in five-dimensional field theories with an SU(1, 3) × U(1) spacetime symmetry.

Enhancing Mechanical Deformability of Rigid Conjugated Polymers through Functional Additive‐Induced Persistence Length Modulation

open access: yesAdvanced 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,

Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

open access: yesAdvanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Inflation, symmetry, and B-modes

open access: yesPhysics Letters B, 2015
We examine the role of using symmetry and effective field theory in inflationary model building. We describe the standard formulation of starting with an approximate shift symmetry for a scalar field, and then introducing corrections systematically in ...
