Microbial Community Restructuring Under Zinc Oxide Nanoparticle Stress in Membrane Bioreactors
Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.Long‐term ZnO nanoparticle exposure induced extracellular stress responses and restructured microbial communities, with reduced taxonomic and phylogenetic richness and loss of key nitrogen‐transforming taxa. These ecological changes were accompanied by impaired nitrification, demonstrating that prolonged ZnO exposure can compromise the functional ...

Synthesis of fire-retardant additive based onwater-insoluble ammonium polyphosphate
, 2020 Water-insoluble ammonium polyphosphate was obtained by sintering of ammonium hydrogen orthophosphate and guanidine carbonate at 250-270 °C. APP was characterized by FTIR, Raman spectroscopy, DSC and NMR 31P.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho
Fisheries Management and Ecology, Volume 33, Issue 5, Page 949-962, October 2026.ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Journal of Applied Polymer Science, Volume 143, Issue 36, September 20, 2026.Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...
