Sustainability Assessment: The Role of Entropy‐Based Indicators for Reconnecting Human' Subjectivity and Civilization With Natural Tendency of Ecosystems

Sustainable Development, EarlyView.
ABSTRACT Sustainability represents a complex issue in which scientific knowledge inevitably coexists with the subjective perception of humans in its turn influenced by civilization, cultural but also unconscious aspects. These results emerge with evidence from a critical analysis of the main definitions of sustainability delivered by credited entities (

Exergy-Anergy Representation of Turbomachine Performance Characteristics

The performance synthesis calculation of aircraft engines relies on tabulated datasets for the simulation of the complex turbomachinery components at acceptable runtimes. Typically, these so-called performance maps express the change of the fluid's energetic state over the component in terms of the total pressure ratio and the isentropic efficiency of ...

Secure Enough? Sufficiency and Security in the New Geological and Geopolitical Reality

Sustainable Development, EarlyView.
ABSTRACT This article advances sufficiency theorizing by examining its relationship with security in the contemporary geopolitical context. It engages three contextually situated discourses: sustainable development, ecological civilization, and degrowth, to explore how concerns over ecological limits intersect with emerging geopolitical and security ...

Scaling‐Up Vanadium Redox Flow Batteries: From Lab‐Scale Flow Cells to Application Stacks

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
The transition of vanadium redox flow batteries (VRFBs) from laboratory cells to practical stacks encounters integrated limitations in key components. This review emphasizes component‐level optimization and engineering considerations for electrodes, electrolytes, membranes, and flow fields. Critical trade‐offs among different metrics across large‐scale
