Solid-state phase transitions of pentadecanoic acid
have been investigated with microscopic observation and
micro-FTIR spectroscopy. Two martensitic phase transitions have
been found; one is a transition from the
B‘ form to the A‘ form, and the other is a transition from A‘ to B‘.
These transitions are initiated by a
mechanical stress. The product phases grow in a definite direction
and are highly oriented. The occurrence
of these transitions depends on temperature. Below 30 °C only
the transition from B‘ to A‘ takes place,
while above 30 °C the direction of the transition is
inverted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
