Colloidal Stability of Self-Assembled Mono layer-Coated Gold Nanoparticles: The Effects of Surface Compositional and Structural Heterogeneity

Francesco Stellacci, Randy Patrick Carney

Surface heterogeneity plays an important role in controlling colloidal phenomena. This study investigated the self-aggregation and bacterial adsorption of self-assembled monolayer coated gold nanoparticles (AuNPs) with different surface compositional and s ...

Effects of Rewarding and Unrewarding Experiences on the Response to Host-induced Plant Odors of the Generalist Parasitoid Cotesia marginiventris (Hymenoptera: Braconidae)

Anthony Christopher Davison, Ingrid Ricard

Associative learning is known to modify foraging behavior in numerous parasitic wasps. This is in agreement with optimal foraging theory, which predicts that the wasps will adapt their responses to specific cues in accordance with the rewards they receive ...
