Dislocation nucleation during nanoindentation of aluminum

Author(s)
Richard J. Wagner, Li Ma, Francesca M. Tavazza, Lyle E. Levine
Through multiscale simulations, we explore the influence of an atomically-rough indenter tip on the nucleation of dislocations during nanoindentation of single...

A review of time and frequency transfer methods

Author(s)
Judah Levine
I will discuss three methods of transmitting time and frequency information: one-way, two-way and common-view. I will describe the advantages and limitations of...

Realizing UTC (NIST) at a Remote Location

Author(s)
Judah Levine
I will describe the backup time scale system that I have constructed at the site of the NIST radio stations near Fort Collins, Colorado, and I will compare its...

Keeping time in three dimensions

Author(s)
Christopher W. Oates
Here I review a paper by Akatsuka et al. that appears in the current volume of Nature Physics. This work describes their latest experimental results on optical...

Blind estimation of general tip shape in AFM imaging

Author(s)
Fenglei Tian, Xiaoping Qian, John S. Villarrubia
The use of flared tip and bi-directional servo control in some recent atomic force microscopes (AFM) has made it possible for these advanced AFMs to image...
