Special Issue "Preparation, Characterization and Application of Ferroelectric/Piezoelectric Nanomaterials"
Deadline for manuscript submissions: closed (31 May 2021).
Interests: ceramics based on barium titanate BaTiO3 (BT); ceramics based on sodium bismuth titanate Bi0.5Na0.5TiO3 (BNT) doped with barium titanate (BNT-BTx); oxide materials; multifunctional composites with new architectures, such as core-shell grains, tubes, core-shell, and thin film heterostructure; wet chemical synthesis methods (sol–gel, gel-combustion, coprecipitation, and hydrothermal)
Ferroelectric materials have functional applications, such as energy harvesting transducers, advanced sensors, actuators in fields of energy, information, and communication. Over the last decade, ferroelectric/piezoelectric nanomaterials have received extensive attention from scientific and engineering viewpoints. They exhibit different properties from those of bulk materials due to their small size and large surface-to-volume ratios and become promising candidates for nanometer scale electronic, optical, and mechanical devices.
Barium titanate (BaTiO3, BT) was one of the first useful piezoelectric materials, but Pb(Zr,Ti)O3 (PZT) is the most widely used ferroelectric material. There is an increasing demand for the development of lead-free materials with similar piezoelectric and ferroelectric properties to the lead-based ceramics. BT continues to be a fundamental system of investigation, but it does not have properties comparable to PZT. For this reason, BT is often used in solid solution with other lead-free compounds, such as sodium bismuth titanate-Na0.5Bi0.5TiO3 (NBT), to form materials with enhanced piezoelectric and dielectric properties.
This Special Issue of Nanomaterials aims to cover the most recent advances in the synthesis procedures for the preparation of ferroelectric/piezoelectric nanomaterials with different compositions, morphologies, and structures in order to enhance their performance and breadth of applications.

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 papers will be 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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Nanomaterials 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 2200 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.
