Scientists Uncover Mystery Behind Crystal's Dual Melting Points

Researchers have solved a 120-year-old mystery regarding the compound acetaldehyde phenylhydrazone, which exhibits two distinct melting points. The phenomenon is due to a minuscule contamination that causes the compound to form two different liquid structures upon melting, depending on exposure to acid or base. This results in the compound having a lower melting point when exposed to acid, which acts as a catalyst for isomer conversion. The study highlights the compound's sensitivity to acid and the role of isomer configurations in its melting behavior.

"Revolutionary Solution: Predicting Melting Points Finally Achieved"

Professor Kostya Trachenko of Queen Mary University of London has solved a 100-year-old physics problem by developing a general theory for predicting melting points, published in Physical Review E. His research unveils a simple parabolic equation that can describe melting lines, offering a universal tool for predicting melting points across different material types. This breakthrough has significant implications for materials science, drug development, and the design of advanced materials, paving the way for a deeper understanding of phase transitions and the creation of new materials with tailored properties.
