Inundation dynamics in seasonally dry floodplain forests in southeastern Brazil

Hydrological Processes, Volume 38, Issue 6, June 2024.
We investigated the variation in water level dynamics for geomorphologically different eco‐units at six floodplain forest sites in southeastern Brazil. The terraces were flooded for ~40 days per year; the levees in the Rio Grande basin for ~4 days per year and levees in the São Francisco basin for ~46 days per year.

New Insights on Biosynthesis of Nanoparticles Using Plants Emphasizing the Use of Alfalfa (Medicago sativa L.)

Journal of Nanotechnology, Volume 2024, Issue 1, 2024.
Biological synthesis of nanoparticles (NPs) using alfalfa (Medicago sativa L.) and other plants has several advantages such as lower costs, reduction of pollution, and improvement of the environment and human health. Often, biosynthesis is used to synthesize Ag, Au, and ZnO NPs. Less often are also synthesized Cu and Fe NPs.
