Source truncation and exhaustion: Insights from quantitative in-situ TEM tensile testing

‚Source truncation and exhaustion: Insights from quantitative in-situ
TEM tensile testing' by D. Kiener and A.M. Minor (http://dx.doi.org/10.1021/nl201890s).

The scientific community was challenged by explaining the uncommon
mechanical properties of microscopic samples, leading to the emergence
of two major schools of thought. One group argued that in miniaturized
samples accordingly small dislocations (the carrier of plastic
deformation) will lead to the extraordinarily strength, while the other
envisioned that only pristine volumes could exhibit such high strength.

In situ nanocompression testing of irradiated copper

Dear colleagues,

we recently published a paper on measuring bulk properties of irradiated copper from nanoscale samples:

Hope you find this interesting!

In situ observation of dislocation nucleation and escape in a submicrometre Al single crystal

Dear colleagues,
Experimental nanomechanics is a frequently discussed topic on imechanica, see e.g. the very active monthly topics by Xiaodong Li, Julia Greer and Wei Cai.
Continuing on this, I would like to draw your attention to a paper we recently published:
"In situ observation of dislocation nucleation and escape in a submicrometre aluminium single crystal" by Sang Ho Oh, Marc Legros, Daniel Kiener & Gerhard Dehm (http://www.nature.com/nmat/journal/v8/n2/abs/nmat2370.html).
