Unified Phase‐Field Framework for Antiferroelectric, Ferroelectric and Dielectric Phases: Application to HZO Thin Films

Advanced Functional Materials, EarlyView.
HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.

Short-term exposure to PM2.5 constituents and mortality risks for diabetes subtypes and related complications in eastern China

Environment International
Background: Although fine particulate matter (PM2.5) pollution is widely linked with diabetes-related morbidity and mortality, research on the short-term effects of its components across diabetes subtypes and complications is limited.

A simple two-module problem to exemplify building-block assembly under crossover

, 2004
Theoretically and empirically it is clear that a genetic algorithm with crossover will outperform a genetic algorithm without crossover in some fitness landscapes, and vice versa in other landscapes.

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization

Advanced Functional Materials, EarlyView.
Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Short-term exposure to fine particulate matter and asthma exacerbation: a large population-based case-crossover study in Southern Thailand

Environmental Health
Background Asthma exacerbations remain a significant global health issue despite advances in management. Fine particulate matter (PM2.5, particles ≤ 2.5 μm in diameter) is a known trigger for asthma exacerbations. However, studies on the acute effects of
