Special Issue Information

Dear Colleagues,

It is my pleasure to announce that the open-access journal Chemistry (MDPI) is now accepting submissions for the upcoming Special Issue on “Phase Transition.”

This Special Issue aims to showcase cutting-edge research focused on phase transitions in condensed matter systems, encompassing a wide range of physical and chemical phenomena. We welcome contributions that explore both equilibrium and nonequilibrium phase transitions induced or influenced by variations in external conditions such as temperature, pressure, mechanical strain, electric and magnetic fields, and irradiation.

We invite high-quality experimental, theoretical, and computational studies that advance the fundamental understanding of phase transitions, as well as those that highlight their technological implications and applications in areas such as materials science, solid-state chemistry, soft matter, and device engineering.

Topics of interest include, but are not limited to, the following:

  • Structural, magnetic, electronic, and superconducting phase transitions;
  • Thermodynamic and kinetic aspects of phase behavior;
  • Metastability and hysteresis phenomena;
  • Phase transitions in low-dimensional or nanostructured materials;
  • Cooperative phenomena and critical behavior;
  • Interface- and defect-driven phase transformations;
  • Phase-change materials for memory and energy applications.

All the submitted manuscripts must be original, unpublished, and not under consideration elsewhere. We aim to provide a rigorous peer-review process and offer rapid publication in an internationally visible and fully open-access platform.

We look forward to your valuable contributions that will help shape this dynamic and interdisciplinary area of research.

Dr. Kenneth Park

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Chemistry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Use of the morphotropic phase boundary (MPB) is a promising approach to enhance the electrocaloric effect in ferroelectric polymers. This is usually achieved by a composition method, and polymer processing near the MPB to tune electrocaloric response has attracted little attention. Here, the relative stability between disordered 3/1-helix and ordered all-trans conformations is leveraged by uniaxial stretching to improve the electrocaloric effect in relaxor ferroelectric polymers under low electric fields. It is found that the stretching technique enables a considerably more enhanced electrocaloric response in polymer composition near the MPB at room temperature, compared with counterparts corresponding to the relaxor phase. The electrocaloric-induced temperature change is found to be 4.5 K under a low electric field of 50 MV m−1 in stretched relaxor ferroelectric polymers at room temperature, corresponding to a 60% enhancement over pristine counterparts. This result highlights the critical role of polymer processing in optimizing electrocaloric properties, especially near the MPB, and this can be extended to improve other functionalities, such as piezoelectric response, in relaxor ferroelectric polymers.
