Lithiation‐Driven LiCrSe2 Shell Growth on Metallic CrSe2 Core Governs the Plateau–Slope Behavior

open access: yesAdvanced Science, EarlyView.
Layered CrSe2 is investigated as a lithium‐ion battery cathode combining fast Li+ diffusion and structural reversibility. Calculations and experiments reveal a single topotactic intercalation process with a characteristic plateau–slope profile governed by lithiation‐induced conductivity changes. A core‐shell lithiation evolution underpins its high‐rate

Halogen‐Bond Coupled Halogenated‐π‐Conjugation Enables Giant Birefringence in Hydrogen‐Bonded Organic Frameworks

open access: yesAdvanced Science, EarlyView.
The perfect crystal packing achieved via the halogen‐bond (XB) coupled halogenated‐π‐conjugation strategy effectively induces an ultrahigh birefringence (Δn = 0.97), which exhibits promising potential in polarization control and phase modulation.

Access for All? The promise and problems of universalism.

open access: yesSocial Work and Society, 2004
In what follows, I explore why the question of ‘access for all’ is both important and difficult. Beginning by treating it as a contested claim, I will consider some of its political, institutional and professional implications.

Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

open access: yesAdvanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

open access: yesAdvanced Electronic Materials, EarlyView.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...
