Hot Carrier Nanowire Transistors at the Ballistic Limit. [PDF]

open access: yesNano Lett
We demonstrate experimentally non-equilibrium transport in unipolar quasi-1D hot electron devices reaching ballistic limit. The devices are realized with heterostructure engineering in nanowires to obtain dopant- and dislocation-free 1D-epitaxy and flexible bandgap engineering.

Uncertainty Considerations for Ballistic Limit Equations [PDF]

open access: yes, 2005
The overall risk for any spacecraft system is typically determined using a Probabilistic Risk Assessment (PRA). A PRA determines the overall risk associated with a particular mission by factoring in all known risks to the spacecraft during its mission ...

Investigating the effects of alumina nanoparticles on the impact resistance of polycarbonate nano-composites [PDF]

open access: yesArchive of Mechanical Engineering, 2022
In this project, two types of treated and untreated alumina nanoparticles with different weight percentages (wt%) of 0.5, 1 and 3% were mixed with polycarbonate matrix; then, the impact ballistic properties of the nano-composite targets made from them ...

Ballistic Limit Estimation Approaches for Ballistic Resistance Assessment

open access: yesDefence Science Journal, 2020
The armour technologist conducts ballistic impact testing either for evaluating armour materials and systems or for studying material’s defeating mechanism. Most standards make use of the ballistic limit velocity for ballistic assessment. This is the bullet impact velocity that leads to the protection perforation in 50 per cent of the cases.
