TEM investigation of helium bubble evolution in tungsten and ZrC-strengthened tungsten at 800 and 1000°C under 40keV He+ irradiation

Autor: I. Ipatova, G. Greaves, D. Terentyev, M.R. Gilbert, Y.-L. Chiu

Publikováno v: Nuclear Engineering and Technology, Vol 56, Iss 4, Pp 1490-1500 (2024)

Helium-induced defect nucleation and accumulation in polycrystalline W and W0.5 wt%ZrC (W0.5ZrC) were studied in-situ using the transmission electron microscopy (TEM) combined with 40 keV He+ irradiation at 800 and 1000°С at the maximum damage leve

In-situ TEM characterization and atomistic simulation of cavity generation and interaction in tungsten at 800 °C under dual W2+/He+ irradiation

Autor: E. Yildirim, P.M. Mummery, G. Greaves, C.P. Race, E. Jimenez-Melero

Publikováno v: Nuclear Materials and Energy, Vol 39, Iss , Pp 101672- (2024)

In this work, we have investigated the role of pre-existing nano-scale cavities and irradiation sequence in helium clustering, and in the evolution of the cavity population in tungsten at 800 °C, by performing in-situ Transmission Electron Microscop

Grain size threshold for enhanced irradiation resistance in nanocrystalline and ultrafine tungsten

Autor: O. El-Atwani, J. A. Hinks, G. Greaves, J. P. Allain, S. A. Maloy

Publikováno v: Materials Research Letters, Vol 5, Iss 5, Pp 343-349 (2017)

Nanocrystalline metals are considered highly radiation-resistant materials due to their large grain boundary areas. Here, the existence of a grain size threshold for enhanced irradiation resistance in high-temperature helium-irradiated nanocrystallin

Engineering self-organising helium bubble lattices in tungsten

Autor: R. W. Harrison, G. Greaves, J. A. Hinks, S. E. Donnelly

Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-8 (2017)

Abstract The self-organisation of void and gas bubbles in solids into superlattices is an intriguing nanoscale phenomenon. Despite the discovery of these lattices 45 years ago, the atomistics behind the ordering mechanisms responsible for the formati

Identification and expression analysis of pineapple sugar transporters reveal their role in the development and environmental response

Autor: Beenish Fakher, Bello Hassan Jakada, Joseph G. Greaves, Lulu Wang, Xiaoping Niu, Yan Cheng, Ping Zheng, Mohammad Aslam, Yuan Qin, Xiaomei Wang

Publikováno v: Frontiers in Plant Science, Vol 13 (2022)

In plants, sugars are required for several essential functions, including growth, storage, signaling, defense and reproduction. Sugar transporters carry out the controlled movement of sugars from source (leaves) to sink (fruits and roots) tissues and
