Evidence for the charge disproportionation of iron in

 · During shock melting, Fe-rich nanoparticles, derived from FeS and FeNi in the host rock, could have been entrapped into silicates crystallizing from shock melt . However, the absence of S and Ni in the metallic-iron nanoparticles (fig. S3) led us to exclude that hiroseite crystallized from shock-induced melt. Instead, our hiroseite sample formed by a subsolidus …

Effects of Acid Rain

 · Melting snow and heavy rain downpours can result in what is known as episodic acidification. Lakes that do not normally have a high level of acidity may temporarily experience effects of acid rain when the melting snow or downpour brings greater amounts of acidic deposition and the soil can't buffer it. This short duration of higher acidity (, lower pH) can …

Nickel, along with iron, is also a common element in meteorites and can even be found in small quantities in plants, animals and seawater.

Productivity gains from teleworking in the post

 · The ongoing health and economic crisis related to the COVID-19 pandemic and the required physical distancing measures force many firms to introduce telework (working from home) on a large scale.

An Introduction to Physical Geography and the Environment

In plant geography and ecology a similar influence was being 8 expressed by Clements in his concept of succession (see Chapter 8). It is notable, however, that two themes of Darwin's work (struggle and selection/randomness and chance) did not have an immediate impact on physical geography (Stoddard, 1966). Indeed the unique contribution of

Cast Irons Selection Guide: Types, Features, Applications

Their melting temperatures are appreciably lower than for steel. Molten iron is more fluid than molten steel and less reactive with molding materials making it excellent for casting. Often dismissed as a cheap, dirty, and brittle metal, cast iron is getting much more attention and use today because of its machinability, light weight, strength, wear resistance, and damping …

Metamorphic rocks

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. The word metamorphism comes from Greek and means 'change of form'.

How much will sea levels rise in the 21st Century?

 · Sea levels are rising due to thermal expansion and melting of land-based ice. Global warming is causing the oceans to absorb a lot of extra heat (up to 90%). This makes the volume of water expand, and sea levels rise. The Greenland and Antarctic ice caps, and many of the world's glaciers, are all slowly melting. The runoff feeds into rivers and directly into the …
