Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Forest Recovery or Shrubland Assembly? Vegetation Dynamics in Abandoned Atlantic Forest Highland Pastures

Biotropica, Volume 58, Issue 3, May 2026.
ABSTRACT Understanding successional trajectories in abandoned lands is critical for predicting forest recovery potential in the Atlantic Forest, a global biodiversity hotspot. Over a decade of field monitoring (2014–2025) in permanent plots in the subtropical highlands of southern Brazil, we analyzed the dynamics of tree‐shrub components in abandoned ...
