TL;DR: In this article, the Atom Probe tomography (APT) was used to examine crack tips and revealed sub-nanometre scale crack chemistry: successive Ni-rich, de-alloyed regions and segregated Fe- and Cr-rich oxides.

TL;DR: The effect of chromium and vanadium alloying on the hydrogenation of a magnesium thin film is studied by neutron reflectometry and in the alloyed film deuteration is rapid and almost completely homogeneous.

TL;DR: In this article, the magnetic moments of (mathrm{double} + 1\mathrm {magic}+1\mathm{proton}$) nuclei having a ''jack-knife'' configuration were measured and analyzed in finite nuclei.
Abstract: The magnetic moments of ( $\mathrm{double}\mathrm{magic}+1\mathrm{proton}$) nuclei having a ``jack-knife'' $j\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}l\ensuremath{-}s$ configuration form crucial tests for the theoretical treatment of mesonic exchange currents and core polarization effects in finite nuclei. The reported precision measurement and analysis of the magnetic moment of ${}^{133}\mathrm{Sb}$ ( ${}^{132}\mathrm{Sn}+\mathrm{one}{g}_{7/2}\mathrm{proton}$) $\ensuremath{\mu}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}3.00(1){\ensuremath{\mu}}_{N}$ provides the first such test in medium-heavy nuclei. In addition, new data on the N dependence of the ${7/2}^{+}{}^{123\ensuremath{-}133}\mathrm{Sb}$ ground state moments are presented. Analysis in terms of particle-core coupling indicates slightly negative collective g factors of heavy Sn core nuclei.

TL;DR: The hypothesis that the low-dose IR induced residual γH2AХ foci do not play a role in delayed irradiation consequences, associated with cellular senescence in cultured MSCs is supported.
Abstract: Mechanisms underlying the effects of low-dose ionizing radiation (IR) exposure (10-100 mGy) remain unknown. Here we present a comparative study of early (less than 24h) and delayed (up to 11 post-irradiation passages) radiation effects caused by low (80 mGy) vs intermediate (1000 mGy) dose X-ray exposure in cultured human bone marrow mesenchymal stem cells (MSCs). We show that γН2АХ foci induced by an intermediate dose returned back to the control value by 24 h post-irradiation. In contrast, low-dose irradiation resulted in residual γН2АХ foci still present at 24 h. Notably, these low dose induced residual γН2АХ foci were not co-localized with рАТМ foci and were observed predominantly in the proliferating Кi67 positive (Кi67+) cells. The number of γН2АХ foci and the fraction of nonproliferating (Кi67-) and senescent (SA-β-gal+) cells measured at passage 11 were increased in cultures exposed to an intermediate dose compared to unirradiated controls. These delayed effects were not seen in the progeny of cells that were irradiated with low-dose X-rays, although such exposure resulted in residual γН2АХ foci in directly irradiated cells. Taken together, our results support the hypothesis that the low-dose IR induced residual γH2AХ foci do not play a role in delayed irradiation consequences, associated with cellular senescence in cultured MSCs.
