Optimization and performance of metafoundations for seismic isolation of small modular reactors
Computer-Aided Civil and Infrastructure Engineering, Volume 38, Issue 12, Page 1558-1582, August 2023., 2023 Abstract This paper aims to study the seismic mitigation of a typical nuclear small modular reactor (SMR) where extreme loading conditions are considered by the safe shutdown earthquake. For this purpose, to reproduce the main dynamic properties of the reactor's reinforced concrete system, a detailed structural model was synthetized, also taking into ...

Nanoparticle Internalization Promotes the Survival of Primary Macrophages
Advanced NanoBiomed Research, Volume 2, Issue 5, May 2022., 2022 Nanoparticle (NP) treatment to macrophages causes enhanced ex vivo survival following a single dose. NP phagocytosis triggers lysosomal signaling, which promotes prosurvival factors and suppresses proapoptotic pathways. NP‐induced survival occurs in the absence of aberrant inflammatory effects.

Science and Technology of Nuclear Installations, Volume 2022, Issue 1, 2022., 2022 The micro‐mechanical state at the crack front is one of the key factors affecting the stress corrosion cracking (SCC) growth behavior. The mechanical heterogeneity and residual stress in the dissimilar metal welded joint (DMWJ) induce the micro‐mechanical state at the crack front to become more complex.
