A Critical Review of Porous Asphalt Mixtures Incorporating Waste Materials: Integrating Functional Performance with Life Cycle Sustainability

Porous asphalt (PA) mixtures offer multifunctional benefits, yet their long-term durability remains a challenge. This study presents a systematic review of recent developments in waste-modified PA, following PRISMA guidelines and analyzing 123 high-impact documents published between 2015 and 2025 across the Web of Science and Scopus databases. Unlike previous works, this paper adopts a multi-waste perspective to synthesize the interactions between recycled modifiers and the open-graded skelet...

Techno-economic analysis of carbon molecular sieve membranes to produce oxygen enrichment air

Oxygen Enriched Air (OEA) is essential for medical applications, metal production, chemical production, the petrochemical industry, and energy processes. In this work, carbon molecular sieve membranes (CMSM) and membrane systems are analyzed concerning their technical and economic feasibility to produce OEA for medical, post-combustion, and oxy-combustion applications. Process parameters, such as stage-cut, feed-to-permeate pressure ratio, membrane area, and the number of stages, were studied...

Modelling ammonia and nitrous oxide decomposition reactions in solid oxide fuel cells for combined energy generation and treatment of flue gas streams

Solid oxide fuel cells (SOFCs) offer a promising technology for clean and efficient power generation. In this study, an SOFC combining in-situ hydrogen generation from ammonia with nitrous oxide reduction to nitrogen was simulated and validated against experimental results for the first time. Ammonia decomposition generates the hydrogen needed for the electroreduction of nitrous oxide, with simultaneous generation of electrical power. Nickel was considered as the anode catalyst since it is hi...
