Carbon Nanopatch‐Decorated Defect‐Rich Regions for Stable Zinc Metal Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To improve the stability of Zn anodes, a carbon‐nanopatch strategy based on candle‐flame pyrolysis is proposed. After rinsing, carbon nanoparticles are mainly retained in defect‐rich regions on the Zn surface, where they help alleviate local field intensification, improve interfacial uniformity, and mitigate parasitic reactions.

A flexible dual‐gate thin‐film transistor‐based tactile sensor array with polarity‐aware encoding for neuromorphic recognition

FlexMat, EarlyView.
A flexible piezoelectric tactile sensor array is developed by integrating polyvinylidene fluoride sensing elements with dual‐gate indium‐tin‐zinc oxide thin‐film transistor‐based pixel amplifiers. Direct coupling to the high‐impedance gate minimizes signal loss, enabling twofold voltage amplification and an extended effective relaxation time of ∼4.86 s

Corrosion Analysis of Rapidly Solidified and Subsequently Aged Al‐Ni and Al‐Fe‐Ni Alloys

Materials and Corrosion, EarlyView.
Fe addition modifies intermetallic phase chemistry and microgalvanic interactions in Al‐Ni alloys, shifting corrosion from generalized dissolution to localized attack. ABSTRACT This study investigates the influence of Fe addition and heat treatment on the corrosion behavior of Al–5 wt.%Ni and Al–2 wt.%Fe–1.5 wt.%Ni alloys, with particular emphasis on ...

In Situ Crystallization‐Induced Coherent Interfaces for Simultaneous Toughening and Hardening of Reinforced Silicon Carbide Nanoceramic

National Materials, EarlyView.
This work reports the fast hot‐pressing sintering of precursor‐derived amorphous SiC raw powders to prepare HfC‐reinforced SiC nanoceramic with coherent HfC/SiC interfaces. Through the synergistic effects of nanocrystallization strengthening and interface engineering, the simultaneous enhancement of three typically competing mechanical properties, that

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

Polymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...
