From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

Harnessing Natural Wood Architecture: A Self‐Supporting, Hierarchically Porous NiFe@Carbon Capacitive Anode Enhances Electricity Generation and Storage in Microbial Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study reports a mild “Zn(NO3)2 interlayer‐expansion” strategy combined with electrodeposition to produce a self‐supporting capacitive anode (NiFe@PC) that preserves the wood's native low‐tortuosity channels. The retained native architecture expands niches for microbial colonization.
