The Effect of Alloying Elements and Impurities on the Composition and Formation of Intermetallic Particles in Titanium and Titanium Alloys

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT The corrosion resistance of alpha and near‐alpha titanium alloys has resulted in their widespread application in extreme environments. Their corrosion behavior is often influenced by their microstructure, particularly intermetallic particles (IMPs), and even slight compositional variations can produce significant differences in microstructure ...

Effect of Metal–Metal Distance on the Performance of Dual‐Atom Catalysts for the Oxygen Reduction Reaction: A Density Functional Theory and Micro‐kinetics Study

open access: yesSmall, EarlyView.
Density functional theory calculations and microkinetic modeling were carried out on 108 dual‐atom catalysts with varied metalmetal distances ranging from 2.2 to 3.5 Å. The results reveal that moderate spacing of around 3.0 Å promotes bridging oxygen adsorption and dissociative reduction pathways, weakens the hydroxylhydroperoxyl scaling relationship ...

Oxidation‐Induced Internal Chemical Patterning in Copper–Gold Nanoalloys

open access: yesSmall, EarlyView.
Surface oxidation suppresses Au surface segregation and redirects Au transport to twin boundaries, replacing conventional core–shell formation with internal chemical patterning. Driven by Cu–Au mixing thermodynamics, defect‐mediated uphill diffusion creates alternating Au‐rich and Cu‐rich lamellae, revealing oxidation as a chemical pump for bulk ...

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

open access: yesSmall, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...

Electroconductive MXene‐Thin‐Film‐Composite Membranes for Coupled Osmotic Concentration and PFAS Mineralization

open access: yesSmall, EarlyView.
An electroconductive MXene‐TFC membrane integrates osmotic dewatering with anodic oxidation to concentrate and mineralize PFOA at the membrane interface. The coupled AO‐PRO configuration accelerates degradation kinetics, achieves 99% rejection and up to 93% TOC removal, and lowers specific energy demand, offering a compact route for PFAS destruction ...
