Alkali Chalcogenido Dialuminates A6[Al2Q6] (A = K, Rb, Cs; Q = S, Se, Te)
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Seven new alkali chalcogenido aluminates A6[Al2Q6] (A = K‐Cs, Q = S‐Te) complement the family of simple metallates(III) A6[M2Q6] (M = Al‐In, FeIII) with dinuclear anions of two edge sharing [AlQ4] tetrahedra. Despite the similar anions, straightforward bonding situation and physical properties, these metallates crystallize in seven different structure ...

Breaking points in the poset of conjugacy classes of subgroups of a finite group [PDF]
, 2019 summary:We determine the finite groups whose poset of conjugacy classes of subgroups has breaking points. This leads to a new characterization of the generalized quaternion $2$-groups.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The here presented compounds Rb3Ln[AsS4]2 with Ln = Gd–Ho represent an extension of the nonisotypic Rb3Ln[AsS4]2 series (Ln = La–Nd, Sm, Gd–Ho). The crystal structures of all representatives of this series contain one‐dimensional chains separated by Rb+ cations.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Normal subgroups in the subgroup lattices of finite $p$-groups
, 2006 Given a finite $p$-group $G$ we construct inductively a chief series only by lattice theoretical means. This improves a result of R. Schmidt that shows that any projectivity between finite $p$ groups $G$ and $H$ sends a chief series of $G$ into a chief ...

On $\sigma $-permutably embedded subgroups of finite groups
, 2019 summary:Let $\sigma =\{\sigma _i\colon i\in I\}$ be some partition of the set of all primes $\mathbb {P}$, $G$ be a finite group and $\sigma (G)=\{\sigma _i\colon \sigma _i\cap \pi (G)\neq \emptyset \}$.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency
Journal of Esthetic and Restorative Dentistry, EarlyView.ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),
