Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

open access: yesMaterials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Multi‐Method Investigation of Intergranular Corrosion of the Aluminium Alloy EN AW‐2024 With Different Cooling Rates After Solution Heat Treatment—Metallography and Eddy Current Testing

open access: yesMaterials and Corrosion, EarlyView.
The corrosion resistance of heat‐treatable aluminium alloys depends directly on the applied heat treatment. This article discusses the relationship between cooling rate and intergranular corrosion sensitivity. The intergranular corrosion depths were determined by light microscopy of cross‐sections and correlated with both non‐destructive eddy current ...

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

open access: yesSmall, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Buried Liquid Metal Interfaces: Oxides and Surface Water‐Driven Hydrogen Bubbles

open access: yesSmall, Volume 22, Issue 48, 26 August 2026.
When liquid metal (EGaIn) is injected against substrates, its native oxide deposits at the buried interface via a tank‐tread mechanism. On glass (insulating) substrates, liquid metal reacts with surface water to generate hydrogen bubbles, with bubble size and density governed by humidity and surface hydrophilicity.

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 ...
