Smart food‐sharing platforms for social sustainability: a heuristic algorithm approach

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 5, Page 2893-2920, September 2026.
Abstract This study examines how smart food‐sharing platforms (SFSP) can help reduce food waste and suggests a method for using smart contracts to share extra food among different partners effectively. For smart contracts to work automatically and prevent food wastage, artificial intelligence systems can recognize how smart clauses should be executed ...

Circular economy business strategies and public schemes: a game theory‐based survey

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 5, Page 2827-2869, September 2026.
Abstract This paper develops a selected survey based on game theory in circular economy (CE) by complementing two perspectives: the CE business strategies and the public schemes (PS) available to implement CE systems. These perspectives are concentrated in six CE business strategies (circular inputs, sharing platforms, product‐as‐a‐service (PaaS ...

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 813-820, July 2026.
We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.
