On New Alkaline Sulfatometallates: Cs6[(WO2)2O(SO4)4], K8[(MoO2)2(SO4)6], K7.9Sr0.1[(WO2)2(SO4)6] and Na4[MoO2(SO4)3]

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Two new alkaline sulfatometallates show promising optical absorption, emission and even non‐linear optical properties together with an astonishingly high thermal stability. The new sulfatotungstate Cs6[(WO2)2O(SO4)4] exhibits a hitherto unknown anion with an unusual W–O–W angle of 180° and edge‐sharing WO6 and SO4 polyhedra.

MOEA/D‐based multi‐row facility layout optimisation method with discontinuity perceiving of the Pareto front

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract In a multi‐row facility layout problem (MRFLP), facilities are arranged in more than one row under the limited layout area. Considering different layout factors, various extensions of MRFLP have been modelled. However, the orientation of input/output (I/O) point in a facility, as a key factor that plays a direct impact on flow cost, is seldom ...

Spatial distribution of 6s2 lone electron pair in Pb4Na(PO4)3 and stereochemical activity of the 6s2 electron cloud in lead‐bearing apatites

open access: yesActa Crystallographica Section B, EarlyView.
In lacunary apatite structure‐type Pb4Na(PO4)3, residual density attributable to the deformed 6s2 electron cloud is found in the vicinity of A2‐site Pb2+ on regular A2 triangle normal to c. Systematic comparison on the size of the A2 triangle with other apatite‐type compounds indicates limited stereochemical activity of the orbital.Single crystals of ...
