Most cancers. Scientists have an interest in spirogermanium, a kind of germanium, as an alternative remedy for many styles of most cancers. But early investigation has shown only nominal response to treatment with spirogermanium. Other early analysis indicates that using propagermanium, another kind of germanium, by mouth for one-seven months may well gain people with multiple myeloma, a type of blood most cancers.
layer recedes within the higher and reduce bounds to leave at the rear of SiO2. Immediately after oxidation and additional annealing in N2 to homogenize the Ge distribution, a thinner layer of Ge
Desi germaniul este un ingredient prezent in toate organismele vii, acesta nu prezinta o functie structurala (cum prezinta siliciul in cadrul unor exoschelete) si nu a fost dovedit ca fiind un component esential pentru plante sau animale[69]. Sax [70] mentioneaza cum germaniul are un caracter scazut al toxicitatii, insa GeH4 are un caracter hemolitic, fiind periculos in cantitati peste one hundred ppm.
Renierite Germaniul este creat de nucleosinteza stelelor, predominant prin procesul-s in ramurile stelelor gigant asimptotice.
ox will be the oxide thickness. The relation previously mentioned motivates the implementation of significant-k elements into gate stacks. The only real way to increase C
)2O3 and subsequently heated to 450 °C less than an Sb flux to induce an amorphous to crystalline transformation of your Ge. The Sb flux was found to scale back surface roughening through recrystallization. The quality of the Ge area, with regard to RMS roughness and TDD, wasn't documented. Web optimization et al.
Studiile pe animale indica faptul ca germaniul, in forma anorganica si organica, sunt absorbiti speedy si aproape complet in tractul respirator si gastrointestinal. Distributia este relativ uniforma in cadrul organelor, insa exista o predispozitie pentru depozitarea acestuia in rinichi si ficat, fiind urmata de o excretie urinara rapida si acumulare pe termen lung in oase.

Cu toate acestea, sărurile sintetice de germaniu Germanium sunt compuși nefrotoxici, iar compușii sintetici ai germaniului cu halogenii și hidrogenul devin toxine și au proprietăți iritante.
Germanium was identified in 1886. Germanium belongs into the carbon family and Employed in electronic products as semiconductors.
This has led some researchers to review their probable use in prescribed drugs. Organic abundance Germanium ores are extremely scarce. These are found in tiny quantities given that the minerals germanite and argyrodite.
