Nghiên cứu của FDA đưa ra kết luận rằng germani, khi sử đụng như là chất bổ sung dinh dưỡng, "thể Helloện một số nguy hiểm tiềm tàng cho sức khỏe con người".[six]
Most cancers. Scientists are interested in spirogermanium, a method of germanium, as an alternative treatment method for numerous kinds of cancer. But early investigate has proven only minimum response to treatment method with spirogermanium. Other early research suggests that using propagermanium, A different form of germanium, by mouth for 1-seven months may reward individuals with various myeloma, a type of blood most cancers.
Demitri Mendeleev, The daddy from the periodic desk, predicted the existence of aspect variety 32, which he named ekasilicon
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 a hundred ppm.

The sublimation and transportation of GeO2 are critical as well as heating temperature of your GeO2 precursor has a great impact on the doping procedure. We conducted a scientific review on T2 temperature from 600, seven hundred, 800 to 900 °C for the duration of the growth. By comparison, the intrinsic undoped h-BN was also grown and characterised (Figs. S8 and S9). As demonstrated in Fig. S10a–d, the rise in the heating temperature of GeO2 impurity precursor will boost the supplying dose of GeO2 and evidently alter the form of h-BN domains. In a low temperature of 600 °C, the triangular-formed h-BN domains exhibit curved edges and blunt angles, which might be unique to the traditional triangular area of undoped h-BN more info (Fig. S8a). This could be attributed into the slight impurity doping. In the event the impurity temperature will increase from 700 to 900 °C, The form of h-BN domains has transferred from triangle to diamond And at last becomes an irregular polygon.

Determine 1b displays that the Ge crystallization progresses with growing annealing time. In accordance with the optical microscopy observations, crystallization was accomplished in just 5 h at 400 °C for all samples. Therefore, the extensive-time annealing for fifty h would adequately unwind the pressure in Ge at 400 °C, leaving the pressure only due to Δα in Ge after cooling.
Currently, this stays the popular signifies to assess gate capacitance, even just after SiO2 is no more the main oxide Utilized in today’s microprocessors. EOT
The skinny depletion region while in the poly-Si as well as finite displacement with the cost centroid (in the channel) within the oxide interface both of those add a further capacitance term showing in series While using the oxide capacitance. For that reason, the gate capacitance is more correctly modeled as:
Nevertheless, even particularly thin layers (below one nm) of Si happen to be proven to passivate correctly and suppress The expansion of Ge’s unstable native oxide [107]. That is below the essential layer thickness of Si on Ge, that has been claimed to become amongst one and 2 nm [142]. The success of Si passivation continues to be demonstrated to get sensitive to the Si development parameters. It had been located that diffusion of Ge to the Si layer was causing increased D
Elemental germanium is often electrodeposited from a lot of answers and melts of its compounds. It's of desire that as minor as a single milligram of dissolved germanium for every litre severely interferes Together with the electrodeposition of zinc.
Germanium may act against inflammation. It may also have antioxidant Houses and have an impact on the immune process.
