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

ENERGY &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

Food 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 ...

Influence of TiO2 content on the physical properties of the CaF2—Al2O3-CaO—MgO—TiO2 five yuan electroslag remelting system

工程科学学报, 2018
The addition of Ti O2during the electroslag remelting (ESR) of Ti-containing superalloys can restrain the loss of Ti elements.The physical properties of the slag system are related to the smooth operation of smelting and the excellent quality of products.

Experimental Determination of Slag Emissivities for Enhanced Slag Control by Infrared‐Based Systems

steel research international
For today's high‐quality steel production, good control of slag composition is essential in secondary steelmaking. However, the conventional slag analysis practice, involving sampling, sample preparation, and analysis, is very time‐consuming. This work is the first step toward an investigation of infrared (IR)‐based systems and can be used for online ...

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

Journal 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.

Thermodynamic modelling on the reaction between steel and slag

Journal of Materials Research and Technology
An integrated thermodynamic model was developed to determine the equilibrium between the slag and the steel at high temperatures, employing the Unified Interaction Parameter Formalism (UIPF) and the Associate Model (AM) for a twelve-element molten steel ...

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

Journal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

Nordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...
