Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

open access: yesLaser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Transient Laser‐Induced Periodic Surface Structures Revealed by Time‐Resolved EUV Diffuse Scattering

open access: yesLaser &Photonics Reviews, EarlyView.
The study shows that femtosecond laser pulses generate transient, LIPSS‐like surface patterns at fluences far below the damage threshold. Time‐resolved extreme ultraviolet scattering captures reciprocal space features that form within a few picoseconds and vanish on sub‐nanosecond timescales.

Breaking Extrapolation Barriers: Dual Innovations for Property and Component Design of Multi‐Component Alloy

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study breaks extrapolation barriers in alloy design by merging symbolic regression with latent space sampling. The dual‐strategy framework enables accurate prediction of high‐hardness properties and navigates uncharted compositional spaces. The approach successfully designs novel high‐entropy alloys with hardness exceeding 863.5 HV, demonstrating ...

Altermagnetismus und neue Chancen für die Spintronik: Das Beste aus zwei Welten

open access: yesPhysik in unserer Zeit, EarlyView.
Sie gelten als die Zukunft der Spintronik: Altermagnete kombinieren die Vorzüge von Ferro‐ und Antiferromagneten, was lange Zeit als physikalisch unvereinbar galt. Der Grund für dieses Potential liegt in ihrer spezifischen Symmetrie. Zusammenfassung Klassisch werden magnetische Materialien in Ferromagnete (parallele Spins) und Antiferromagnete ...

Evaluation of a stochastically perturbed parametrisations scheme for sea ice in sub‐seasonal forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Overconfident sea ice forecasts pose a challenge in subseasonal prediction. To test a potential way to address this issue and account for sea ice model uncertainty, this article investigates a stochastically perturbed parametrisations (SPP) scheme for sea ice in a prototype CY49R2 configuration of the coupled IFS‐NEMO4‐SI3 system. The results show that

How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...
