Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

Sustainable Revival of Spent Lithium Iron Phosphate Cathodes in Li‐Ion Batteries: Recycling and Surface Engineering Approaches

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration of the lifecycle of LiFePO4 cathodes. Lithiation and delithiation reactions happen through its discharging and charging processes. Recycling pathways including hydrometallurgy, pyrometallurgy, and direct regeneration enable sustainable reuse of spent LFP materials. Surface modification approaches (carbon, polymer, and metal/metal

Anti‐Inflammatory Effects of Punicic Acid and Its Molecular Mechanisms in RAW264.7 Cells and Zebrafish

open access: yesFood Safety and Health, EarlyView.
Punicic acid (PA) was enriched and purified from PSO by molecular distillation with significant anti‐inflammatory activity to RAW264.7 cells, as well as to zebrafish. Anti‐inflammatory mechanism involved regulating NF‐κB and MAPK signaling pathways. ABSTRACT Punicic acid (PA) is the main fatty acid in pomegranate seeds, which shows multiple biological ...

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

The Behavior of Ceramic Fiber Geopolymer Concrete under the Effect of High Temperature

open access: yesApplied Sciences
Geopolymer concrete (GC), also known as green concrete, contains slag, silica fume, and fly ash as binders. The absence of cement in concrete is critical to protect the world from the environmental impacts of cement production.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

An Investigation of Fly Ash and Slag Processing and Fiber Production Using Plasma Technology

open access: yesApplied Sciences
As the world’s population grows and resource consumption rises, there will be an increase in household waste and, consequently, the fly ash and slag from after the incineration of this waste need to be properly recycled or used as secondary raw materials
