Rb4CuSb2X12 (X = Cl, Br) as Novel Vacancy‐Ordered Quadruple Perovskites

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The vacancy‐ordered quadruple perovskites Rb4CuSb2X12 (X = Cl, Br) were crystallized from hydrohalic acid. Their crystal structures can be interpreted as new distortion variants of the perovskite structure with ordered vacancies. The electronic structure of Rb4CuSb2Br12 shows that the Br and Sb states form the valence band and the upper conduction band.

Delamination of Vermiculite into Ultrahigh‐Aspect‐Ratio Nanosheets

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Efficient ion exchange allows for thermodynamically driven delamination of vermiculite into high‐aspect ratio nanosheets. The applicability of sustainable materials in the packaging industry is currently limited by the poor gas barrier performance of most biodegradable polymers.

Investigation of the Simplified Equivalent Circuit Model of the Post‐Arc Sheath Stage in DC Vacuum Circuit Breakers

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper presents a simplified equivalent circuit model (ECM) for the post‐arc sheath stage in DC vacuum circuit breakers and outlines the method for calculating circuit parameters using the particle‐in‐cell Monte Carlo collision (PIC‐MCC) method. The post‐arc sheath is modelled as a parallel combination of a variable resistor and a variable
