Germanium nanocrystals in SiO2 with an average diameter of 5–25 nm were fabricated by co-deposition and annealing at 700–1000 °C. X-ray diffraction and transmission electron microscopy were used to measure the nanocrystal growth as a function of anneal time and temperature. The precipitation of nanocrystals was found not to follow the theory for precipitation from a solid …
Germanosilicate zeolites have played a pivotal role in the recent surge in synthesis of novel zeolite topologies. This success has been attributed to the combined effect of the high hydrolytic lability and specific distribution of germanium within the zeolitic framework, e.g., favoring the double four-ring (D4R) structural units. While experimental determination of …

The experimental and computational results showed that bond strength differences between germanium and tin, as well as greater nonbonded electron pair stabilization for tin, are more important than steric factors in determining the product obtained.
Introduction. Germanium (Ge) is a relatively rare metal, with a chemical symbol of Ge, that belongs to the carbon group of elements and is found in nature in minerals [].Germanium can also be extracted and refined from ores containing high levels of germanium, typically through methods such as smelting and extraction.
