Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Forage production of elephant grass under intermittent stocking
Pesquisa Agropecuária Brasileira, 2013 The objective of this work was to evaluate the dry matter production of elephant grass (Pennisetum purpureum) genotypes, managed under intermittent stocking. A completely randomized design was used, with two genotypes and three replicates. The treatments
