Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

open access: yesSmall, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Binary Fraction in Galactic Star Clusters: FSR 866, NGC 1960, and STOCK 2

open access: yesThe Astronomical Journal
The study of binary stars in different astronomical environments offers insights into the dynamical state of the hosting stellar systems. The binary fraction in fact plays a crucial role in the dynamical evolution of stellar systems, regulating processes

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

open access: yesWildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Characterization of the Blue Straggler Star Populations, through Statistical, Photometric, and Spectral Energy Distribution Analysis, in the Old Open Cluster: NGC 2243

open access: yesThe Astronomical Journal
We present a statistical, photometric, and spectral energy distribution (SED) analysis of the poorly studied old open cluster: NGC 2243, to characterize its blue straggler star (BSS) population.
