Comparative study on corrosion behavior of plasma sprayed Al2O3, ZrO2, Al2O3/ZrO2 and ZrO2/Al2O3 coatings

Transactions of Nonferrous Metals Society of China, 2016
Abstract ZrO2, Al2O3, ZrO2/Al2O3 and Al2O3/ZrO2 coatings were fabricated on low carbon steel using atmospheric plasma spraying technique. The microstructure and phase composition of the as-sprayed coatings were examined by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively.

Heterosynaptic Memtransistors Based on Switching Operation Mechanism Using Designed Organic/Inorganic Heterostructures for Neuromorphic Electronics

Advanced Science, EarlyView.
Heteroysynaptic memtransistors are fabricated using a combination of π‐conjugated organic semiconductor TCTA and TMDC MoS2 heterostructure with bottom‐contact architecture. Non‐volatile heterosynaptic and homosynaptic functions such as long‐term plasticity and spike‐timing‐dependent plasticity are emulated by drain and gate pulses based on conduction ...

Hierarchical Embedded Sphere Model: An Interpretable ML‐Guided Multiscale Descriptor Engineering Decodes OER Activity on TM@MO2 Catalysts

Advanced Science, EarlyView.
Hierarchical Embedded Sphere Model combines DFT and interpretable machine learning to decode catalytic activity on TM‐doped MO2. It disentangles global electronic, active‐site, and local coordination effects, revealing two activation mechanisms: dopant‐driven (Rh@MO2) and coordination‐mediated (Fe@ZrO2).

Improved Air Stability of Li Argyrodites Through PS43− Rotation Suppression by Al and Se Co‐Substitution for All‐Solid‐State Batteries

Advanced Science, EarlyView.
Al/Se co‐substitution in Li6PS5Cl achieves enhanced dry‐air stability and improves Li+ conductivity, retaining 85% of its high Li+ conductivity (4.91 mS cm−1 at 30 °C) after dry‐air exposure (dew point −40 °C for 5 h). The stability enhancement is experimentally validated and underpinned by theoretical analyses indicating suppressed rotation of P[S2SeO]

Low‐Voltage and High‐k Properties of Bilayer HZO Capacitors at the Morphotropic Phase Boundary for Next‐Generation Memory Applications

Advanced Science, EarlyView.
The HfxZr1‐xO2‐based ferroelectric/antiferroelectric bilayer capacitor exhibits morphotropic‐phase‐boundary behavior with a high dielectric constant (∼52) at 2 V. Phase engineering stabilizes o/t‐phase coexistence and suppresses m‐phase formation, enabling capacitance enhancement and self‐optimization under cycling for scalable low‐voltage, high‐κ ...
