Heteroengineering‐Induced Electronic Reconstruction for Ammonium‐Ion Energy Storage

open access: yesAdvanced Functional Materials, EarlyView.
An integrated electronic reconstruction behavior is induced by local heteroengineering on VO2(B) electrode material surface of NH4+ supercapacitor, rationally modulating the electronic structure, enabling enhanced intrinsic conductivity and extra driving force for NH4+ intercalation reaction.

Synthesis and studies of new chromophores for two-photon PDT and of bimodal systems for two-photon PDT and MRI

open access: yes, 2014
There is an increasing interest in the emerging field of "theranostic" whose aim is to improve the diagnosis and to monitor the treatment of the disease. This can be achieved by combining a diagnostic and a therapeutic agent within the same system.[1] We

Spectral profiles of two-photon absorption : Coherent versus two-step two-photon absorption

open access: yes, 2005
We present a theory of two-photon absorption in solutions which addresses the, formation of spectral shapes taking account of the vibrational degrees of freedom.

Orbital Engineering through Strain‐Induced Spin–Orbit–Lattice Coupling in Sr2FeReO6 Double Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.

Photoswitching of the Two‐Photon Absorption of Donor‐Acceptor Substituted Dithienylethenes

open access: yesChemistryEurope
In this work the structural and electronic integration of push–pull systems with photoactivatable dithienylethenes (DTEs) is demonstrated. The light‐induced 6π‐electrocyclization of two asymmetrically substituted DTEs is used to conjugate an electron ...

Material Coupling in Hybrid Neuromorphic Devices: From Fundamentals to System‐Level Applications

open access: yesAdvanced Functional Materials, EarlyView.
Hybrid neuromorphic devices utilize heterointerfaces between emerging semiconductors, where charge transfer and trapping, ion or defect modulation, and photogating are translated into synaptic functions. This paper discusses coupling strategies that tailor interfacial electronic and ionic properties in organic semiconductors, metal oxides, two ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...
