Low‐Loss Far‐Infrared Surface Phonon Polaritons in Suspended SrTiO3 Nanomembranes

open access: yesAdvanced Functional Materials, EarlyView.
The low‐loss, highly confined, and thickness‐tunable surface phonon polaritons are demonstrated in the far‐infrared regime within transferable freestanding SrTiO3 membranes, achieving high figures of merit comparable to the previous record values from the vdW materials.

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Variation-Diminishing Wavelets and Wavelet Transforms

open access: yesReal Analysis Exchange, 2012
Using Schoenberg's theory of variation-diminishing integral operators of convolution type variation diminishing wavelets and wavelets of specific changes in sign are constructed. An inversion formula involving derivatives of the wavelet transform is established.

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu

open access: yesAdvanced Functional Materials, EarlyView.
From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.
