In-situ AFM and quasi-in-situ studies for localized corrosion in Mg-9Al-1Fe-(Gd) alloys under 3.5 wt.% NaCl environment

Journal of Magnesium and Alloys
Revealing the localized corrosion process of Mg alloy is considered as one of the most significant ways for improving its corrosion resistance. The reliable monitor should be high distinguishability and real-time in liquid environment. Herein, Mg-9Al-1Fe

SKPFM measured Volta potential correlated with strain localisation in microstructure to understand corrosion susceptibility of cold-rolled grade 2205 duplex stainless steel [PDF]

, 2015
Scanning Kelvin Probe Force Microscopy (SKPFM) of annealed and cold-rolled grade 2205 duplex stainless steel has been correlated with microstructure analysis using Electron Back-Scattered Diffraction (EBSD).

Sub-Microscopic Phenomena of Metallic Corrosion Studied by a Combined Photoelectron Spectroscopy in Air (PESA) and Scanning Kelvin Probe Force Microscopy (SKPFM) Approach

International Journal of Electrochemical Science, 2012
The management of metallic corrosion has relied on large-scale, ultra-conservative protection strategies such as the extensive use of anti-corrosion metals and alloys, all-inclusive coating and surface passivation, and substantial use cathodic protection.

Performance Assessment and Lab‐Scale Economic Evaluation of Alkaline Extraction and Comparative Precipitation of Cyanobacterial Proteins

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Algal proteins from cyanobacteria serve as a natural source of biopolymers. The principal challenge manifests as nonoptimization of unit operations in downstream process accounting for higher costs. This study focuses on process assessment of unit‐operations for selecting suitable recovery strategies not only based on yield, but also considers

From Conspicuous to Conscious Consumption: A Cross‐Cultural Study of Motivation, Self‐Congruity and Luxury Rentals

Journal of Consumer Behaviour, EarlyView.
ABSTRACT The luxury market is shifting from conspicuous to conscious consumption, with access‐based consumption such as luxury rental having gained momentum as an alternative retail channel. Drawing on Self‐Determination Theory, this study investigates how sustainability motivation (intrinsic) and social recognition motivation (extrinsic) influence ...

Rethinking Assessment in C‐STEAM Education: A Culturally Responsive Framework for Ghanaian Secondary Schools

Future in Educational Research, EarlyView.
ABSTRACT The study investigated how a culturally grounded 6C instructional model aligns with assessment practices in C‐STEAM education across 30 Ghanaian secondary schools (N = 720; 600 students, 120 teachers). It was found that integrating local cultural content significantly increased student engagement and ownership.

Controlling micro-galvanic-driven pitting corrosion in Al–Mn–Cu alloys through compositional tuning of Mn and Cu

Journal of Materials Research and Technology
Localized corrosion in Al–Mn alloys is driven by micro-galvanic coupling between the Al matrix and intermetallic compounds (IMCs). The matrix–IMC potential difference is well established as the driving force for this coupling, yet strategies to control ...

New Insights About the Role of Sn‐Rich and Pb‐Rich Phases Over the Corrosion Mechanism of Low‐Tin Quaternary Bronze Alloys Under Sulfur‐Containing Conditions

Materials and Corrosion, EarlyView.
A mechanistic proposal for the initial steps of quaternary bronze corrosion in media containing sulfate was described. The process is driven by microgalvanic effects along the microstructure, generating anodic sites over lead and tin rich phases and cathodic sites onto Cu‐rich phases.

The Effect of Heat Treatment on the Localized Corrosion Susceptibility of Extruded AA6063 Alloys With High Amount of Tramp Elements

Materials and Corrosion, EarlyView.
In AA6063 variants with increased Cu and Zn contents, T6 heat treatment increased local electrochemical contrast, promoting earlier trenching and more frequent intergranular corrosion initiation. Non‐heat‐treated variants developed fewer but larger intergranularly corroded regions, showing that T6 shifts localized corrosion from propagation toward ...
