Journal ArticleDOI
In-situ TEM observation of the response of ultrafine- and nanocrystalline-grained tungsten to extreme irradiation environments
Osman El-Atwani,Jonathan A. Hinks,Graeme Greaves,S. Gonderman,T. Qiu,Mert Efe,Jean Paul Allain +6 more
TL;DR: A dynamic and complex evolution in the microstructure was observed including the formation of defect clusters, dislocations and bubbles, indicating the important role grain boundaries can play in trapping He and thus in giving rise to the enhanced radiation tolerance of nanocrystalline materials.
Journal ArticleDOI
Helium bubble formation in ultrafine and nanocrystalline tungsten under different extreme conditions
Osman El-Atwani,Khalid Hattar,Jonathan A. Hinks,Graeme Greaves,Sivanandan S. Harilal,Sivanandan S. Harilal,Ahmed Hassanein +6 more
TL;DR: In this paper, the effects of helium ion irradiation energy and sample temperature on the performance of grain boundaries as helium sinks in ultrafine grained and nanocrystalline tungsten were investigated.
Journal ArticleDOI
Grain size threshold for enhanced irradiation resistance in nanocrystalline and ultrafine tungsten
TL;DR: In this paper, the existence of a grain size threshold for enhanced irradiation resistance in high-temperature helium-irradiated nanocrystalline and ultrafine tungsten is demonstrated.
Journal ArticleDOI
Enhanced sputtering yields from single-ion impacts on gold nanorods.
Graeme Greaves,Jonathan A. Hinks,P. Busby,Nigel J. Mellors,A. Ilinov,Antti Kuronen,Kai Nordlund,Stephen E. Donnelly +7 more
TL;DR: Molecular dynamic modeling reveals that the range of incident angles occurring for irradiation of nanorods and the larger number of atoms in "explosively ejected" atomic clusters make a significant contribution to the enhanced yield.
Journal ArticleDOI
In-situ observation and atomic resolution imaging of the ion irradiation induced amorphisation of graphene
C. T. Pan,Jonathan A. Hinks,Quentin M. Ramasse,Graeme Greaves,Ursel Bangert,Stephen E. Donnelly,Sarah J. Haigh +6 more
TL;DR: Electron diffraction studies performed during simultaneous in-situ ion irradiation have allowed the first atomic resolution scanning transmission electron microscopy images of ion-irradiation induced graphene defect structures together with quantitative analysis of defect densities using Raman spectroscopy.
