Abstract: Abstract The structural evolution of nano Cu-precipitates was studied with high-resolution transmission electron microscopy. 9R Cu precipitates were mainly multiple-twinned. However, the unusual 9R Cu precipitates with no twins were also observed. The 9R→face-centered tetragonal… read more here.

Abstract: Bird communities in lowland Neotropical forests exhibit temporal and spatial variation in species composition and abundance at multiple scales. Detecting and explaining such variation requires adequate methods for sampling those bird communities but counting birds… read more here.
