Gallium‐assisted entropy engineering of high‐entropy oxide nanoparticles for solar/electrical dual‐mode thermal management textiles

open access: yesInfoMat, EarlyView.
Solar/electrical dual‐mode thermal management textiles. Abstract High‐entropy oxides (HEO) offer an emerging platform for broadband photothermal conversion because multicationic disorder can simultaneously regulate crystal distortion, valence chemistry, and electronic transitions.

Single‐Lens Counter‐Focused Ultrashort Laser Pulses for Enhanced Microplasma Formation Inside Silicon

open access: yesLaser &Photonics Reviews, EarlyView.
A polarization‐dependent liquid–crystal spatial light modulator is used to generate coaxial double‐focus laser beams with independently tunable focal separation and intensity. Applied to silicon, this configuration enables counterpropagating pulse interactions using a single focusing element, enhancing nonlinear excitation and achieving near‐critical ...

Resilience for restoration: Insights from the Northern Great Plains native seed system

open access: yesPeople and Nature, EarlyView.
Abstract Native plants are essential to ecological restoration and culturally important to local and Tribal communities, yet native seed systems across the United States (US) struggle to meet restoration demand. In the US Northern Great Plains, land conversion of native ecosystems means restoration potential is high but constrained by an underdeveloped
