The flow liquefaction phenomenon. Theoretical and practical approach
Geotecnia, 2022 In recent years and due to the increase in mining activity, the number of events that have brought catastrophic and sudden ruptures in the mine waste deposits, with the loss of numerous human lives, has increased. In many cases, the main cause of these failures has been interpreted as flow liquefaction.

European Ports as Energy Hubs: A Sustainability Index to Assess Territorial Development
Business Strategy and the Environment, EarlyView.ABSTRACT The capacity of ports to act as energy hubs is increasingly relevant in light of sustainability challenges and global crises like the Ukraine conflict, the COVID‐19 pandemic and energy scarcity. Numerous international and national initiatives are shaping the future of port development to address environmental and economic concerns.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

Pore-scale Modeling of Viscous Flow and Induced Forces in Dense Sphere Packings
, 2013 We propose a method for effectively upscaling incompressible viscous flow in large random polydispersed sphere packings: the emphasis of this method is on the determination of the forces applied on the solid particles by the fluid.

Carbon Energy, EarlyView.Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...

Influence of clay mineralogy on undrained cyclic strength of sand with fines
Engineering Science and Technology, an International JournalSoils in natural or reclaimed areas frequently contain a mixture of sand, silt, and clay, rather than consisting solely of clean sand. The influence of a small proportion of fine plastic particles within a sandy matrix on liquefaction resistance still ...

Carbon Energy, EarlyView.An ultrastrong, hierarchically nanoporous gel polymer electrolyte (GPE) was fabricated via poly(ionic liquid)‐induced interfacial coacervation of cellulose nanofibrils. Its cascade ion‐conduction network enables dual‐mode Li⁺ transport via nanoconfinement and interstitial hopping. The GPE enables stable cycling of high mass loading battery (LiFePO₄, 16
