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.

Stress and Strain State Analysis of Crack Front in Dissimilar Metal Welded Joints with Dual Field of Mechanical Heterogeneity and Residual Stress

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.

Experimental Research for CHF Sensitivity of Heat Flux Distribution under IVR Conditions

Science and Technology of Nuclear Installations, Volume 2022, Issue 1, 2022., 2022
In‐vessel retention (IVR) through external reactor vessel cooling (ERVC) is one of the most effective severe accident mitigation measures in the nuclear power plants. The most influential issues on the IVR strategy are in‐vessel core melt evolution, the heat fluxes imposed on the lower head, and the external cooling of reactor pressurized vessel (RPV).
