A comparative study of rafting mechanisms of Ni-based single crystal superalloys
Materials & Design, 2020 It is known that Ni-based superalloys experience microstructural rafting during high temperature straining. This paper presents a comparative study of the different rafting models by means of finite element modeling and experimentation investigation.

Chemical inhomogeneity–induced profuse nanotwinning and phase transformation in AuCu nanowires
Nature Communications, 2023 Nanosized metals usually exhibit ultrahigh strength but suffer from low homogeneous plasticity. The origin of a strength–ductility trade-off has been well studied for pure metals, but not for random solid solution (RSS) alloys. How RSS alloys accommodate

Mechanical Properties of Axons
Physical Review Letters, 2007 The mechanical response of PC12 neurites under tension is investigated using a microneedle technique. Elastic response, viscoelastic relaxation, and active contraction are observed. The mechanical model proposed by Dennerll et al. [J. Cell Biol. 109, 3073 (1989).10.1083/jcb.109.6.3073], which involves three mechanical devices--a stiff spring kappa ...

On the Sharpness and Bias of Quantum Effects [PDF]
, 2009 The question of quantifying the sharpness (or unsharpness) of a quantum mechanical effect is investigated. Apart from sharpness, another property, bias, is found to be relevant for the joint measurability or coexistence of two effects.

Mechanical and Nanomechanical Properties
, 2007 The growing interest in nanomaterials over the past decade or so can be put down to their unique structure, characterised by grains with nanometric dimensions and by a rather high density of crystal defects, which will undoubtedly lead to quite exceptional properties. In particular, extrapolating the constitutive laws of large-grained materials down to

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
