Surface engineering of recycled high‐density polyethylene‐based wood–polymer composites via carbon black‐containing surface film coating

Coloration Technology, EarlyView.
Abstract This study evaluates carbon black nanoparticle (CB NP)‐reinforced surface films for improving the durability, thermal stability, fire performance and mechanical retention of recycled high‐density polyethylene (HDPE)‐based wood‐plastic composites (WPCs) after 12 months of natural weathering.

NextGenerationEU Landing: Assessing the Territorial Allocation of Italy's Recovery and Resilience Facility Funding

Journal of Regional Science, EarlyView.
ABSTRACT In response to the COVID‐19 crisis, the European Union introduced NextGenerationEU, its largest stimulus package to date. We focus on Italy, the program's largest beneficiary, and analyse the territorial distribution of funds. Although centrally coordinated, most expenditures were awarded through calls and implemented by local governments ...

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Integration of hBN Single‐Photon Emitters Into a Hybrid Optomechanical Membrane‐In‐The‐Middle Fiber‐Cavity

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Deterministic manipulation of hexagonal boron nitride (hBN) flakes enables single‐photon emitters (SPEs) to be integrated into a fiber‐based Fabry–Pérot membrane‐in‐the‐middle cavity. Cavity coupling enhances and spectrally funnels the broadband emitter fluorescence, while allowing access to mechanical membrane modes for future hybrid optomechanical ...
