Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

AI‐Enhanced Vibrational Capsule for Minimally Invasive Detection of Abnormal Bowel Tissue

Advanced Science, EarlyView.
A fully integrated vibration‐assisted capsule is presented for the minimally invasive detection of bowel lesions. The capsule incorporates a wireless sensor and an eccentric motor to probe tissue mechanics in situ. By coupling triaxial vibration signals with AI‐based classification and analytical modeling, the system enables early, non‐visual ...

Informational Analysis for Compressive Sampling in Radar Imaging

Sensors, 2015
Compressive sampling or compressed sensing (CS) works on the assumption of the sparsity or compressibility of the underlying signal, relies on the trans-informational capability of the measurement matrix employed and the resultant measurements, operates ...

Mitigating Electrochemical Isolation in Ni‐Rich Layered Cathodes for Durable Solid‐State Batteries

Advanced Science, EarlyView.
Electrochemical isolation of Ni‐rich layered cathodes in sulfide solid‐state batteries is uncovered as a previously unrecognized but critical performance‐limiting pathway. This study elucidates its origin and impact and introduces a scalable mitigation strategy using oxygen‐functionalized conductive carbon.

Ferroelectric‐Polarization‐Driven Structural Engineering of Bi3Nb17O47 Anodes for High‐Performance Lithium‐Ion Batteries

Advanced Science, EarlyView.
A transformative ferroelectric‐polarization strategy is employed to overcome the intrinsic limitations of tungsten bronze (TTB)‐type anode materials in metal‐ion batteries, using Bi3Nb17O47 as a model system. By exploiting the non‐centrosymmetric crystal structure and field‐induced ionic displacements, controlled structural engineering with ...

All Solid Lithium Metal‐Polymer Battery End‐of‐Life: an Investigation of Symmetric, Battery, and Bilayer Cells

Advanced Science, EarlyView.
In this study, the evolution of the lithium (Li)/polymer interface is compared in a realistic pouch cell configuration, either in Li/Li symmetric cell or in full Li/LiFePO4${\rm LiFePO}_4$ batteries thanks to X‐ray micro‐tomography. While Li/Li symmetric cells are the reference cell for probing the interface stability, results demonstrated that the end‐

Synergistic Modulation of Ru–O Bond Covalency via Ba/Fe Co‐Doping and Oxygen‐Vacancy Engineering for Efficient Wide‐pH Oxygen Evolution

Advanced Science, EarlyView.
Ba/Fe co‐doping and oxygen vacancy engineering synergistically modulate the Ru–O bond covalency in RuO2, leading to markedly enhanced OER activity across wide‐pH electrolytes. ABSTRACT Developing efficient and stable oxygen evolution reaction (OER) catalysts across a wide‐pH range is critical for practical water electrolysis.

Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse

Advanced Science, EarlyView.
An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...
