Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures

River Research and Applications, EarlyView.
ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

Mechanistic Insight into H2S‐Induced Fluorescence Quenching in a Robust Metal–Organic Framework

Small, EarlyView.
An ultramicroporous Zn‐based metal‐organic framework, MFM‐520, enables reversible hydrogen sulfide adsorption and selective fluorescence sensing. Confinement of H2S within the pores perturbs ligand‐centered excited states through weak host‐guest interactions, enhancing non‐radiative decay pathways.

Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

steel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
