Chemical and nanoindentation study of diffusion during sintering of 12Ce-ZrO2/3Y-ZrO2 powder layers

open access: yes
Tetragonal zirconia polycrystals doped with 3% mol of yttria (3Y-ZrO2) exhibit excellent mechanical properties and biocompatibility. However, under humid environments, their surface structural integrity is degraded by aging (low temperature degradation).

Challenges and strategies toward next‐generation high‐performance flexible and printable thin‐film transistors

open access: yesFlexMat, EarlyView.
This review explores recent progress in printing strategies such as inkjet, screen, liquid metal, and roll to roll (R2R) methods and their roles in fabricating flexible TFTs. Device architectures are examined with emphasis on printed components and their influence on performance and stability.

Spatiotemporal engineering of dynamic color in alternating‐current‐driven light‐emitting devices

open access: yesFlexMat, EarlyView.
This review presents a mechanism‐driven framework for spectral tuning in alternating‐current‐driven light‐emitting devices, systematically integrating emissive center engineering, device architecture design, and driving signal modulation. By linking microscopic carrier dynamics and electric‐field‐charge interactions with macroscopic spectral evolution,

Recent Paradigms in Nanomaterial‐Assisted Electrochemical (Bio) Sensing for Food Quality and Safety Analysis: A Critical Review

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Rising global demand for safe and unadulterated foods has accelerated the need for rapid, low‐cost, and portable analytical technologies. Traditional laboratory methods, although accurate, are often labor‐intensive and unsuitable for decentralized, real‐time monitoring. In response, nanomaterial‐assisted electrochemical sensors have emerged as

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Antiferroelectric Phase Transitions Under Electric Fields: A Review of Physics and Applications

open access: yesInterdisciplinary Materials, EarlyView.
Field‐induced phase transitions in antiferroelectric materials, driven by electric field, temperature, or stress, enable diverse applications including energy storage, electrocaloric cooling, and negative capacitance. These transitions are regulated through compositional design, strain engineering, heterostructure, and size effect, providing a unified ...
