Tuning the Phase Structure and Electrical Properties of BNKT‐Based Ceramics via Li+ Doping

Advanced Materials Interfaces, EarlyView.
Li+‐doped Bi0.5[Na0.84‐xK0.16Lix]0.5TiO3 lead‐free piezoelectric ceramics are fabricated. The optimized composition delivers a high piezoelectric coefficient d33 and elevated depolarization temperature Td. It also shows large electrostrain and high Curie temperature, greatly extending the working temperature range for BNT‐based piezoelectric ...

Melanin pathway genes regulate color and morphology of butterfly wing scales

bioRxiv, 2017
The cuticular skeleton of a butterfly wing scale cell serves both as a substrate for the deposition of pigments and as an exquisitely finely-sculpted material responsible for the production of structural colors.

Lead‐Free Bismuth Halide Perovskite Memristors: Low‐Voltage Switching and Physical Modeling of Resistive Hysteresis

Advanced Materials Technologies, EarlyView.
Lead‐free bismuth halide perovskite memristors exhibit stable low‐voltage resistive switching behavior. The conductance‐activated quasi‐linear memristor model quantitatively reproduces the experimental hysteresis, confirming ion migration‐driven filament dynamics.

On Phenomenological Failure Loci of Metals under Constant Stress States of Combined Tension and Shear: Issues of Coaxiality and Non-Uniqueness

Metals, 2019
The present study investigates how the choice of characterization test and the composition of the stress state in terms of tension and shear can produce a non-unique failure locus in terms of stress triaxiality under plane stress conditions.

Past, current, and potential future distributions of unique genetic diversity in a cold‐adapted mountain butterfly

Ecology and Evolution, 2020
Aim Climatic changes throughout the Pleistocene have strongly modified species distributions. We examine how these range shifts have affected the genetic diversity of a montane butterfly species and whether the genetic diversity in the extant populations

Charge diffusion and the butterfly effect in striped holographic matter

, 2016
Recently, it has been proposed that the butterfly velocity - a speed at which quantum information propagates - may provide a fundamental bound on diffusion constants in dirty incoherent metals.

Beyond Brown: Lignin's Emerging Role in Structural Color

Advanced Optical Materials, EarlyView.
Lignin, long regarded as a brown industrial byproduct, is emerging as a sustainable platform for structural color. This Perspective highlights how lignin's refractive index, intrinsic absorption, and nanoscale assembly enable tunable photonic responses in colloidal and thin‐film architectures, and outlines design strategies to advance scalable, bio ...
