The effect of graphene on the activation energy of grain growth for the nanocrystalline thermoelectric n-type Bi2Te2.7Se0.3
Published 2022“…For the composite samples, a lower graphene weight percentage (0.05 wt.%) increased the activation energy to 270 kJ/mol. In contrast, higher amounts of graphene (0.5 wt.%) reduced the activation energy significantly to 254 kJ/mol. …”

Effects of habitat complexity on the abundance, species richness and size of darkling beetles (Tenebrionidae) in artificial vegetation
Published 2016“…At the high levels of habitat complexity used in this study, the main effect of increasing complexity was excluding beetles from higher complexity treatments, particularly larger beetle species. The 6 mm (highest complexity) treatment had significantly lower abundance than the other three treatments. …”
