Photoluminescence Enhancement in Erbium Nanoparticles via Controlled Phase Transformation

Small, Volume 22, Issue 24, 27 April 2026.
Er‐NPs synthesized by PLAL were thermally treated from 200°C to 1000°C. Annealing at 600°C produced a full transition to the cubic Er2O3 phase and removed non‐radiative surface species. This led to a fivefold increase in PL. The results show how oxidation and phase purity control the optical performance of Er‐NPs.

A Multi Tracer Approach Reveals Groundwater Residence Times and Dynamic Endmember Mixing in the Subterranean Estuary of a High Energy Beach

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Subterranean estuaries (STEs) under high‐energy conditions function as effective biogeochemical reactors, where waterbodies of varying physico‐chemical properties mix. Chemical reactions within the STE modulate the solute composition of groundwater discharging to the sea providing for example nutrients for plankton growth to coastal ecosystems.

Bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii Chatton 1914 (Dinophyceae)

Journal of Phycology, Volume 62, Issue 2, Page 666-688, April 2026.
Abstract Heterotrophic dinoflagellates are important predators of phytoplankton, and many species produce bioluminescence, which is thought to serve as an antipredator function. The present study investigated the bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii, an important predator of toxic and bloom‐forming dinoflagellates ...

Decadal Shifts in Groundwater Age Detected by Environmental Tracers Across California, USA

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Groundwater age offers important insight into recharge, storage, and contamination risk. Although models predict age changes can be driven by pumping and climate variability, direct observational evidence remains limited. Here, we analyzed paired environmental tracer suites (tritium, carbon‐14, and tritiogenic helium‐3) collected a decade ...

The effect of citrus essential oil encapsulation on antioxidant capacity and bacterial growth in a milk matrix during storage

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2352-2360, 15 March 2026.
Abstract BACKGROUND The functionality of food can be improved by supplementing it with bioactive substances. However, the interactions between these substances and food components can compromise their functional efficacy. This study investigated the potential to reduce functional losses by encapsulating citrus essential oil (CEO) in zein particles (ZPs)

Influence of plateau, slope, and valley on soil hydrology during the dry season in a Central Amazon old‐growth forest

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Soil moisture regulates plant water supply and drought sensitivity in tropical forests, yet its vertical and topographic variation remains poorly characterized. We combined high‐frequency time‐domain reflectometry measurements from 5 to 100 cm across plateau, slope, and valley landforms at the Zona Florestal 2 research site north of Manaus ...

The absolute mass of neutrino and the first unique forbidden beta-decay of 187Re

, 2011
The planned rhenium beta-decay experiment MARE might probe the absolute mass scale of neutrinos with the same sensitivity as the tritium beta-decay experiment KATRIN, which will start data taking in 2011 and will proceed for five years.
