Characteristics of (Sr0.92Y0.08)0.85Ti1‒xNixO3‒𝛿 (x = 0.05, 0.10, 0.15, 0.20) perovskites for internal dry methane reforming in solid oxide fuel cells

open access: yesJournal of the American Ceramic Society, EarlyView.
Ni‐doped Sr0.92Y0.08TiO3 perovskite has been investigated to improve the catalytic activity for CO2 dry internal reforming of methane in SOFCs. A‐site‐deficient SYTN perovskites eluted 3‒5 nm sized Ni nanoparticles onto the surface. The non‐stoichiometric perovskite catalysts improved the CO2 dry reforming performance as well as enhancing ...

Ex–ante LCA for circular resource management of liquid digestate, by predictive modeling of algae–bacterial processes

open access: yesJournal of Industrial Ecology, EarlyView.
Abstract The simplest method for treating liquid digestate, which involves directly spreading it over local agricultural land, is facing scrutiny due to the challenges of transporting large volumes and the environmental risks posed by nitrogen and phosphorus pollutants.

Circular ecosystems: Past, present, and future research directions

open access: yesJournal of Industrial Ecology, EarlyView.
Abstract Circular ecosystems have become a buzz concept in the circular economy, but differing meanings and theoretical foundations limit knowledge consolidation. To address this gap, we undertook a systematic literature review of the circular ecosystems literature published from 2004 to 2025. We analyzed the state‐of‐the‐art using content analysis and
