WebOct 15, 2024 · Ni and Co variations in primary martian magmas exhibit anomalous incompatible behavior, which has remained an unexplained conundrum. Because martian magmas are S-rich, and some trace metals are reported to have enhanced solubility in S-bearing magmas, we have carried out a series of experiments to evaluate the effect of … Webon the second half of a peak. Like the onset, users may choose the second tangent line to find the endset of a melting transition or the first tangent line to find the end point of a recrystallization event. • Peak Apex: The location of the max peak value is subject to multiple variables. Its value is
WebWhile macromolecular crystallization can occur from only the melt or solution state, the crystallization during polymerization can occur from the monomer being in either gaseous or condensed state. It is thus also possible to get chain folded crystals below the glass transition temperature of the final polymer (e.g. 100°C below Tg for poly (p ...
