Prioritized Lithium Extraction From Spent Lithium‐Ion Batteries via Low‐Temperature Chlorination Mediated by Seawater‐Derived Chlorides

open access: yesRare Metals, EarlyView.
ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Quantifying Efficiency Roll‐Off Factors in Quantum‐Dot Light‐Emitting Diodes

open access: yesAdvanced Science
The application of quantum‐dot light‐emitting diodes (QLEDs) is hindered by efficiency roll‐off at high current densities. Factors contributing to this roll‐off include Auger recombination, electric field‐induced quenching, Joule heating, and electron ...

Optimizing CuO on 3D Ordered Macroporous CeO2 for CO Oxidation in Rich Hydrogen

open access: yesRare Metals, EarlyView.
ABSTRACT CO preferential oxidation (CO‐PROX) in rich H2 is considered a feasible strategy to solve CO poisoning for fuel cells, but obtaining good activity at low temperatures is still a challenge. Herein, three‐dimensional ordered macroporous (3DOM) CuO/CeO2 catalysts were fabricated by a templating approach, with the metal–support interaction (MSI ...

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

open access: yesSmall, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Correlative Chemical Imaging to Reveal the Nature of Different Commercial Graphene Materials

open access: yesSmall Methods, EarlyView.
Commercial graphene‐based materials from different sources and of varying complexities were investigated correlatively using commonly employed imaging techniques, including SEM, AFM, ToF‐SIMS, AES, and EDS. ToF‐SIMS combined with SEM was identified as the most effective combination for simultaneously resolving the complex morphology and chemical ...

Primitive Ligands Drive 1D CsPbI3 Nanostructures with Strongly Polarized Photoluminescence

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
This work illustration highlights I− concentration drives the structural evolution of CsPbI3 from cubic to orthorhombic phase, accompanied by octahedral distortion. In addition, increasing I− transforms nanorods into ginkgo‐leaf‐like assemblies, including a 659–683 nm PL redshift due to bandgap narrowing and strain effects.

Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys

open access: yessteel research international, EarlyView.
This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...
