In some cases the answers are obvious, while in others even the most elaborate means of investigation may fail to provide a full answer. Yet the neuro-surgeon's aim should be to provide full answers where possible, as only then is he in a posit...

In an alloy subject to vacancy-mediated diffusion, differences in intrinsic diffusivities tend produce vacancy excess and deficit. These are accommodated by mechanisms such as dislocation climb pore formation. This is of concern high temperature alloy-coating systems used industrial applications, pores may develop at the interface between coating, which undesired. paper presents a multicomponen...

A back-gated nonplanar floating gate device based on buried single triangular-shaped Si nanowire channel (width ∼40 nm) and embedded high-density uniform NiSi nano-dots (∼1.5× 1012 cm−2) is demonstrated. Memory properties including memory window, programming/ erasing, and retention are evaluated. The transfer and transient characteristics show clear charge injection, storage and removal effects...
