Metathesis of Ge=Ge double bonds

Nature Chemistry, 2021
The metathesis of carbon-carbon double bonds-the 'reshuffling' of their constituting carbene fragments-is a tremendously important preparative tool in industry and academia. Metathesis of heavier alkene homologues is restricted to occasional unproductive examples in phosphorus chemistry and cross-metathesis to mixed heavier alkynes.

Band structures of GaGeAsGe and InGeAsGe superlattices

Solid State Communications, 1989
Abstract The band structure of [001]- oriented GaGeAsGe and InGeAsGe superlattices is calculated using the self-consistent pseudopotential method, and the ionic pseudopotential of Ge is determined. The equilibrium lattice parameter and positions of constituent atoms of the superlattices are determined using pseudopotential perturbation ...

Voluntary GE-filters and further results of GE-filters in GE-algebras

2022
Summary: Further properties on (belligerent) GE-filters are discussed, and the quotient GEalgebra via a GE-filter is established. Conditions for the set \(\vec{c}\) to be a belligerent GE-filter are provided. The extension property of belligerent GE-filter is composed. The notions of a balanced element, a balanced GE-filter, an antisymmetric GE-algebra

A thermodynamic evaluation of the Ge-In, Ge-Pb, Ge-Sb, Ge-Tl and Ge-Zn systems

Thermochimica Acta, 1989
Abstract Five germanium-based binary systems have been thermodynamically assessed as a part of a long-term programme to provide thermodynamic data bases in order to perform calculations in multi-component systems. For each system, Ge-In, Ge-Pb, Ge-Sb, Ge-Tl and Ge-Zn, a set of self-consistent parameters has been obtained by using the optimization ...

New compounds with Ge/Ge and Ge/C multiple bonds

Journal of Organometallic Chemistry, 2006
Abstract Treatment of GeCl2 · dioxane with the Grignard reagent RMgBr (R = 2,5-tBu2C6H3) furnishes the tetraaryldigermene R2Ge GeR2 (4). The X-ray structure analysis of 4 reveals a long Ge Ge double bond of 236.4 pm and the largest trans-bending angles of the substituents (42.6° and 37.2°) observed so far.

On GE-ideals of bordered GE-algebras

2023
Summary: In this paper, the properties of GE-ideals of transitive bordered GE-algebra are studied and characterizations of GE-ideals are given. We have observed that the set of all GE-ideals of a transitive bordered GE-algebra forms a complete lattice.

Powder metallurgy of Ge, Si, and Ge-Si

Journal of Crystal Growth, 1993
Abstract Planetary ball-milling and pressing behaviour of Ge, Si and Ge-Si powder mixtures are investigated. Scanning and transmission electron microscopy observations revealed the different microstructure of the two elements after milling: Ge remains in a microcrystalline state, whereas Si can be comminuted into grains consisting of nanocrystalline ...
