Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

Swift heavy ion irradiation of Pt nanocrystals: I. shape transformation and dissolution
We report on the effects of swift heavy ion irradiation of embedded Pt nanocrystals (NCs), which change from spheres to prolate spheroids to rods upon irradiation.

The STEM characterization of dislocation loops in MA956 ODS steel after swift heavy ion irradiation
For the purpose of clarifying the basic mechanism of material failure caused by irradiation damage, the microstructures of materials under extreme radiation conditions were evaluated by transmission electron microscopy (TEM).

Composition Control in CuInZnS2 Nanocrystals by Cation Exchange and Their Phase Transfer
This work elucidates the composition‐defining parameters for CuInZnS2 (CIZS) nanocrystals (NCs) prepared by a cation exchange reaction. Investigations focus on their cation shares and size, which influence both the absorbance and the bandgap. Furthermore, a novel ligand exchange route from 1‐dodecanthiol to 11‐mercaptoundecanoic acid is shown, thereby ...

Structural properties of nano-porous GaSb prepared by swift heavy-ion irradiation
We are investigating the structural and optical properties of nano-porous GaSb formed by swift heavy ion irradiation using a combination of high resolution structural characterization techniques including synchrotron based small- and wide-angle X-ray ...

Nature of Surface Microcracks on Phosphorus Micro‐Alloyed Copper
SSRT tests and microscopic characterization methods were used to study the effect of plastic deformation and environment on the formation of surface microcracks on Cu‐OFP. Results show that, while ambient conditions produced thousands of microcracks per mm2, exposure to sulfide water resulted in fewer microcracks with no evidence of crack growth ...

Amorphization of Ta2O5 under swift heavy ion irradiation
Abstract Crystalline Ta 2 O 5 powder is shown to amorphize under 2.2 GeV 197 Au ion irradiation. Synchrotron X-ray diffraction (XRD), Raman spectroscopy, small-angle X-ray scattering (SAXS), and transmission electron microscopy (TEM) were used to characterize the structural transition from crystalline to fully-amorphous.

Iron and Other Metal Ions in Human Health and Disease
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Periodic poling of optical waveguides produced by swift-heavy-ion irradiation in LiNbO3
The generation of periodically poled structures in waveguides prepared by swift-heavy-ion (SHI) irradiation, i.e. in the electronic stopping power regime, has been achieved following two different strategies.

ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
