Where is graphite found on Earth

Graphite is often found as flakes or crystalline layers in metamorphic rocks such as marble, schist, and gneisses. Graphite may also be found in organic-rich shales and coal beds. In these cases, the graphite itself probably resulted from the metamorphosis of dead plant and animal matter. The strongest material in the universe may be the whimsically named "nuclear pasta." You can find this substance in the crust of neutron stars. This amazing super-dense material is 10 billion times harder to br

What's the strongest metal on earth

Tungsten, Swedish for "heavy stone," is the strongest metal in the world. It was identified as a new element in 1781. It is commonly used to make bullets and missiles, metal evaporation work, manufacturing of paints, creating electron and Television tubes, and making glass to metal seals. The cost of making Titanium is about six times greater than that of stainless steel. As a result, its uses have remained limited to speciality parts for aerospace, high-end items like jewellery or other niche a

The single compound with the highest melting point on Earth is hafnium carbide

Hafnium carbide, also known as HfC (hafnium-carbonide), is a chemical mixture of hafnium & carbon. This binary compound is among the least refractory. It has a melting point around 3900°C. The compound is resistant to oxidation, but it can be oxidized at temperatures as low and as high as 430°C. It may also be used in the heat shield on future spacecraft. Is hafnium carbide toxic? Animal studies have shown that hafnium oxychloride is toxic through the intraperitoneal route. Hafnium has not

Characterization of ATO NPs

So far, we noticed the absence of light soaking and photo-shunt as potential advantages of n-type SnO2 NPs over ZnO-based ETMs. Next, we extended our investigations to the ATO NPs and clarified the nature of the polarity and the doping mechanism. We selected Sb3+for two reasons: firstly, Sb3+is expected to be a p-type dopant as compared to Sb5+; second, Sb3+(0.76Å) has an ion radius that is comparable to that of Sn4+(0.69Å), potentially facilitating substitutional doping rather than interstitial
