Record High Polarization at 2 V and Imprint‐Free Operation in Superlattice HfO2‐ZrO2 by Proper Tuning of Ferro and Antiferroelectricity

Advanced Materials Technologies, EarlyView.
Low‐power ferroelectric capacitors, based on superlattice HfO2‐ZrO2 is reported. With proper tuning of ferro and antiferroelectricity, an imprint‐free high switchable polarization charge (2Pr of 76 µC/cm2) is obtained with 2MV/cm leading to linear analog weight update and non‐volatile retention, providing a design guideline for emerging non‐volatile ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Unraveling Mechanism of Photoluminescence in Hybrid Indium Halide Materials

Advanced Optical Materials, EarlyView.
Halide substitution in isolated [InHal6]3− octahedra reveals how bromide incorporation governs photoluminescence properties in hybrid indium halides. Ligand‐to‐metal charge transfer excitation followed by recombination produces a red‐shift and steadily increasing photoluminescence efficiency with increasing Br content.

High‐Performance Ternary Organic Solar Cells via Isomeric Engineering of Nonfullerene Guest Acceptors

Advanced Science, EarlyView.
Two isomeric nonfullerene acceptors, BTP‐γ‐Br and BTP‐δ‐Br, were designed to investigate their effects on the optoelectronic properties and photovoltaic performance of ternary blends. Incorporating BTP‐γ‐Br into the D18:N3 binary system can enhance film crystallinity and suppress charge recombination, achieving a high PCE of 19.2% and a certified JSC ...

Electronic Structure Reorganization in MPS3 via d‐Shell‐Selective Alkali Metal Doping

Advanced Science, EarlyView.
Alkali metal doping of layered MPS3 antiferromagnets reveals d‐shell‐selective responses. While MnPS3 resists charge transfer due to its half‐filled 3d5 shell, FePS3 and NiPS3 behave similarly to CoPS3 by accommodating extra d‐electrons. Yet only CoPS3, with its least stable d‐shell, undergoes pronounced band restructuring and a semiconducting‐to ...

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.

2-{[(1S,2S)-1-Hydroxy-1-phenylpropan-2-yl](methyl)amino}-N-(3-methylphenyl)acetamide

IUCrData
The title compound, C19H24N2O2 (m-TAP), was synthesized via the reaction of 2-chloro-N-(m-tolyl)acetamide with pseudoephidrine. It crystallizes in the monoclinic crystal system with a non-centrosymmetric chiral space group P21 (No. 4).

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

Advanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.
