For an excellent fifty yrs, germanium was little over a box to the periodic desk. It seriously was not superior for something. It was only with the development of electronics that germanium's value as an extremely successful semiconductor arrived to light-weight.
All appropriate knowledge that help the conclusions of the analyze can be obtained in the corresponding writer on request.
V. Raja & Andrew R. Barron (OpenStax CNX) by means of supply written content that was edited for the fashion and standards with the LibreTexts System; a detailed edit heritage is accessible upon ask for.
Acest factor nu are o funcție vitală pentru organisme, iar unii compuși organici ai germaniului au fost testați ca și posibile produse farmaceutice, însă fără nici un rezultat. Similar cu siliciul și aluminiul, compușii germanici tind să fie insolubili în apă, având astfel un potențial scăzut de toxicitate orală.
The wellness promises produced for germanium aren’t properly supported by research. Based on the Memorial Sloan Kettering Most cancers Centre, there’s no scientific proof to help its use for dealing with arthritis, HIV, or AIDS. Human studies also recommend it’s not well suited for treating cancer.
A 2012 research examined modifications in rat fecal bacteria and located no correlation that Ge-132 accrued in rat bodies by weighing the body organs. It ought to be famous that no organs had been analyzed for germanium stages to confirm accumulation didn't come about.
To spatially Find precise pigments and binding media, ATR mapping was executed on the region highlighted using a box in Figure (PageIndex 37 ). The Untrue shade images together with Just about every spectrum in Figure (PageIndex 38 ) show the relative presence from the compound corresponding to Each individual spectrum within the boxed region.
A evaluate of your stiffness of a substance. It offers a measure of how challenging it is to increase a material, with a price given by the ratio of tensile toughness to tensile pressure.
Naturally, scattering procedures are rather weak at prolonged optical wavelengths. As an example, the intensity of Rayleigh scattering – scattering at objects that happen to be significantly scaled-down when compared to the wavelength – scales While check here using the inverse fourth electricity from the wavelength.
Do not blow air or nitrogen throughout the ports as this could cause mechanical deformation within the salt window Should the stress is superior plenty of.
Germaniul nu prezinta un rol biologic in organism, desi actioneaza ca un stimulent metabolic. Sarurile de germaniu prezinta toxicitate scazuta pentru mamifere, insa au caracter letal pentru bacterii (fara a rezulta o aplicare practica a acestui comportament).
Applying our ad bundle, you could display your logo, more down below your solution description, and these will been viewed by quite a few photonics pros.
Area the salt pellet mixture into one other opening of the nut and amount by tapping the assembly on a countertop.
