Highly symmetrical B12@Mg20C12 with icosahedral B12 motif: A potential hydrogen storage medium
A highly symmetrical core–shell Ih B12@Mg20C12 structure containing icosahedral B12 motif has been proposed in the framework of density functional theory.

Icosahedral B12-containing core–shell structures of B80
Low-lying icosahedral (I(h)) B(12)-containing structures of B(80) are explored, and a number of core-shell isomers are found to have lower energy than the previous predicted B(80) fullerene. The structural transformation of boron clusters from tubular structure to core-shell structure may occur at a critical size less than B(80).

Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Exciton Footprint of Self-assembled AlGaAs Quantum Dots in Core-Shell Nanowires [PDF]
Quantum-dot-in-nanowire systems constitute building blocks for advanced photonics and sensing applications. The electronic symmetry of the emitters impacts their function capabilities. Here, we study the fine structure of gallium-rich quantum dots nested

Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Continuum and Three-Nucleon Force Effects on 9Be Energy Levels
We extend the recently proposed ab initio no-core shell model with continuum to include three-nucleon (3N) interactions beyond the few-body domain. The extended approach allows for the assessment of effects of continuum degrees of freedom as well as of ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
