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

open access: yesAsia-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

open access: yesJournal 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

open access: yesFuture 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.

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

open access: yesMaterials 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.
