Dispersion‐Less Dissipative Soliton Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

Optimized Copper Distribution and Enhanced Coercivity in PrO2‐Doped Sm2Co17‐Type Magnets

open access: yesRare Metals, EarlyView.
ABSTRACT A rational design of Cu distribution is crucial for achieving optimal magnetic properties in Sm2Co17‐type magnets. In this study, nanostructured PrO2 powders were employed to induce Cu redistribution at grain boundaries while preserving the cellular microstructure. The corresponding coercivity (Hcj), remanence (Br), and maximum energy product (

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

open access: yesRare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

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.

Unlocking Klockmannite: Formation of Colloidal Quasi‐2D CuSe Nanocrystals and Photo‐Physical Properties Arising From Crystal Anisotropy

open access: yesSmall, EarlyView.
Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...

Efficient, Reversible Lead Adsorption in a Thiol‐Decorated Zirconium‐Metal–Organic Framework

open access: yesSmall, EarlyView.
A thiol‐decorated Zr‐MOF, Zr‐DMSA, efficiently captures Pb(II) from water via mixed S/O chelation enabled by flexible “dangling” ligands, as revealed by solid‐state NMR and pair distribution function analyses. Treatment with 1 M HCl fully reverses Pb binding, regenerating the material for up to 10 consecutive adsorption–desorption cycles.
