“You just want to re‐open our biggest wounds, don't you?”: Homeplace ethnography as (polluted) environmental method

open access: yesFeminist Anthropology, EarlyView.
Abstract When I was 12, my family told me a story about their community falling apart and coming together, a time when someone tried putting a nuclear facility in their (our?) hometown. Since we moved when I was too young to remember, the story had little significance until I embarked on a “hometown” ethnographic journey for my dissertation.

Fabrication of Al-Cu Alloy via Additive Friction Stir Deposition

open access: yesJournal of Manufacturing and Materials Processing
This study fabricated AA2024-T4 aluminum alloy components using Additive Friction Stir Deposition (AFSD) to systematically investigate the effects of tool rotational speed (100–400 rpm) on the macroscopic morphology, microstructure, and mechanical ...

Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind jointly control dust emission and near‐surface transport. A closed‐circuit wind

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

open access: yesMaterials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Comparison of Aluminum Alloy and Copper Friction Stir Burnishing Tools Combined with Direct Energy Deposition Arc Process on Microstructure and Microhardness of 316L Stainless Steel

open access: yesJournal of Manufacturing and Materials Processing
The direct energy deposition arc process is widely used for fabricating medium and large components with moderate geometric complexity but often results in coarse microstructures and inconsistent hardness.

Effect of Heat Treatment on Hydrogen Embrittlement of Electrodeposited Copper

open access: yesMaterials and Corrosion, EarlyView.
This work explores how entrapped hydrogen can cause embrittlement of copper, although this embrittlement is only evidenced during slow strain testing. We demonstrate that significant amounts of hydrogen are trapped in nano‐cavities and investigate the impact of heat treatment in changing the hydrogen distribution and the resulting embrittlement ...

Achieving simultaneous strength-ductility-corrosion optimization of solid-state additive friction stir deposited superlight Mg-Li alloy by a hybrid high flow rate Argon/CO₂ shielding atmosphere

open access: yesJournal of Magnesium and Alloys
High-performance Mg–Li alloys were fabricated via solid-state additive friction stir deposition under a mixed Ar/liquid CO₂ atmosphere, which addresses severe oxidation and unfavorable thermal cycling issues during additive manufacturing. Benefiting from

Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

open access: yesSmall, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...
