Phase Transitions: Melting and Freezing

13.0K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Area of Science:

  • Materials Science
  • Solid-State Chemistry
  • Crystallography

Background:

  • Prussian blue analogues (PBAs) are versatile coordination compounds with diverse applications.
  • Understanding the structural dynamics of PBAs under different conditions is crucial for their optimal use.
  • Disordered PBAs present unique challenges and opportunities for materials innovation.

Purpose of the Study:

  • To report the discovery and characterization of a novel metastable phase in flash-frozen disordered Prussian blue analogues.
  • To investigate the structural and symmetry changes associated with this new phase.
  • To elucidate the potential mechanism driving the formation of this metastable phase.

Main Methods:

  • Flash-freezing of disordered Prussian blue analogues.
  • X-ray diffraction (XRD) analysis to observe scattering patterns.
  • Analysis of local structure symmetry and space groups.
  • Characterization of phase transitions via translational modulation.

Main Results:

  • Identification of a new metastable phase in flash-frozen disordered PBAs.
  • Observed diffuse scattering clouds indicating structural disorder.
  • Reduction in local structure symmetry from cubic to tetragonal or lower.
  • Phase transition characterized by translational modulation of the structure.

Conclusions:

  • The freezing of confined water within the PBA pores is the likely cause of the observed metastable phase.
  • This discovery offers new insights into the phase behavior of PBAs under cryogenic conditions.
  • The findings could influence the design and application of PBAs in fields requiring structural stability at low temperatures.
