A Robust Cost‐Effective Spectrophotometric Method for Nb Determination in Refractory Nb‐doped Gadolinium Zirconate: Overcoming Matrix Dissolution Challenges

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT A simple, robust and cost‐effective analytical methodology was developed for the determination of niobium in highly refractory materials: Nb‐doped gadolinium zirconate (Gd2Zr2O7:Nb) and niobium pentoxide (Nb2O5). The challenge of digesting these matrices was successfully accomplished by establishing two independent dissolution procedures: (i ...

Effect of soiling agents on disinfection efficacy of a pulsed‐xenon UV lamp towards Listeria monocytogenes on stainless steel surfaces

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2786-2796, June 2026.
This study quantifies the effects of different soils found in the food processing environment on the efficiency of pulsed‐xenon UV disinfection. Abstract Listeria monocytogenes is a foodborne illness that poses a significant threat to human health in young, old, and immunocompromised persons and accordingly, prevention of Listeria contamination is of ...

Induction of Apoptosis in MCF‐7 Breast Cancer Cells by Selenium Nanoparticles Synthesized With Laccase Enzyme Isolated From Pleurotus Floridanus

eFood, Volume 7, Issue 3, June 2026.
This study showed the first successful synthesis of selenium nanoparticles (SeNPs) using laccase purified from Pleurotus floridanus, offering an eco‐friendly and biocompatible replacement to conventional chemical methods. The biosynthesized SeNPs exhibited significant antiproliferative effects on MCF‐7 breast cancer cells, with cell cycle analysis ...

Riparian Restoration Improves Physical Habitat but Not Ecosystem Functioning to Reference Levels in Urban Neotropical Streams

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Urbanization modifies stream ecosystems through changes in land use and water quality, with particularly understudied effects in tropical regions. This study evaluates how the conservation status (reference, restored, and impacted) influences nutrient enrichment and organic matter decomposition—key indicators of ecosystem function—across five ...
