5,6-Dibromo-1H-indole-2,3-dione
The title compound, C8H3Br2NO2, crystallizes with two near planar molecules in the asymmetric unit, with non-H atoms possessing mean deviations from planarity of 0.012 and 0.014 Å. The two molecules are connected by an N—H...O and a C—H...O hydrogen bond.

Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

On the Book Thickness of 1-Planar Graphs
In a book embedding of a graph G, the vertices of G are placed in order along a straight-line called spine of the book, and the edges of G are drawn on a set of half-planes, called the pages of the book, such that two edges drawn on a page do not cross each other. The minimum number of pages in which a graph can be embedded is called the book-thickness

The molecule of the title compound, C8H4INO2, is almost planar, having an r.m.s. deviation from planarity of 0.019 Å for all non-H atoms. In the crystal, molecules are linked by pairs of N—H...O hydrogen bonds, forming inversion dimers with an R22(8 ...

Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

1,1′-Di-tert-butyl-2,2′,3,3′,4,4′,5,5′-octaethyl-1,1′-bistannole
The title compound, [Sn2(C4H9)2(C12H20)2], has two 1-stannacyclopentadiene skeletons related by inversion symmetry located at the mid-point of the Sn—Sn bond [2.7682 (2) Å].

This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

3D Visibility Representations of 1-planar Graphs [PDF]
We prove that every 1-planar graph G has a z-parallel visibility representation, i.e., a 3D visibility representation in which the vertices are isothetic disjoint rectangles parallel to the xy-plane, and the edges are unobstructed z-parallel visibilities between pairs of rectangles.

Three novel 5-(2-haloethyl)pyrimidine derivatives were synthesized and characterized by 1H-NMR, 13C-NMR, MS, IR spectra and elemental analysis. Iodine and chlorine atoms in the C-5 side chain were introduced by reaction of 5-(2-hydroxyethyl)pyrimidine ...
