Nonstoichiometric Compounds VIII

November 2024
Tainan, Taiwan

About This Conference

The aim of this conference is to bring together scientists from diverse disciplines, who are working on nonstoichiometric compounds (oxides, nitrides, oxynitrides, chalcogenides, etc.). Traditionally, the effects of stoichiometry deviations have been studied by those looking to understand and control the electrical, diffusional, and in many cases, the mechanical properties of oxides, with the aim of using such materials as battery electrodes, fuel cell electrodes, permeation membranes, and in various other electrochemical reactors. 

The use of nonstoichiometric compounds has expanded in recent years. For example, complex oxides that exhibit nonstoichiometric effects are being employed in high Tc superconducting devices and memory devices, Furthermore, driven by the semiconductor industry interest has also expanded to include nitrides, chalcogenides, oxynitrides, oxychalcogenides, etc. Given the diverse fields of applications, it is clear that a truly international conference devoted specifically to compounds that display nonstoichiometry will allow scientists from these various fields to learn from the other fields and from other approaches, to assess the state of the art, and to discuss future developments.

The first conferences on nonstoichiometric compounds were held at the beginning of the 1980s. Then, after a break of more than ten years, UEF-sponsored conferences that focused on “Nonstoichiometric Ceramics and Intermetallics” were held in 1998 and 2001, followed by the ECI conferences on “Nonstoichiometric Compounds” in Kauai, Hawaii, USA in 2005 and on Jeju Island, Korea in 2009. The decision to return to the former name of the conference was determined, as noted above, by the desire to reach a wider audience. Contributions on intermetallics will, of course, be welcomed.  However, the emphasis will be on nonstoichiometric compounds.

The last conference “Nonstoichiometric Compounds” in Miyazaki, Japan, in March 2019, was again very successful. With an increasing demand for advances nonstoichiometric materials in various fields of science and engineering, we expect to run an attractive conference.

This conference will cover all aspects of nonstoichiometry in inorganic compounds. The main themes are: fundamentals, applications, characterizations, and theory. Materials will include single crystalline, polycrystalline and nanocrystalline ceramics with possible applications as, e.g., solid oxide fuel cells, batteries, sensors, permeation membranes, superconductivity, switching and memory devices, etc. The conference will last four and 1/2 days and each half-day session will consist of two keynote talks, followed by shorter presentations on current research topics germane to the keynote talks. There will also be two poster sessions.

The conference will consist of topical sessions on:

1. Fundamentals: point defects 
2. Fundamentals: extended defects, interfaces and surfaces 
3. Applications: batteries
4. Applications: fuel cells and electrolyzers
5. Applications: memory devices 
6. Characterizations: high resolution, time resolved and in-situ
7. Theory: atomistic 
8. Theory: continuum and devices

General Information about ECI

Engineering Conferences International (ECI) is a not-for-profit, global engineering conferences program, originally established in 1962 that provides opportunities for the exploration of problems and issues of concern to engineers and scientists from many disciplines.

The format of the conference provides morning and late afternoon or evening sessions in which major presentations are made. Poster sessions will be scheduled for evening discussion as well. Available time is included during the afternoons for ad hoc meetings, informal discussions, and/or recreation. This format is designed to enhance rapport among participants and promote dialogue on the development of the meeting. We believe the conferences have been instrumental in generating ideas and disseminating information to a greater extent than is possible through more conventional forums.

All participants are expected both to attend the entire conference and to contribute actively to the discussions. The recording/photographing of lectures and presentations is forbidden. As ECI conferences take place in an informal atmosphere, casual clothing is the usual attire.

Smoking is prohibited at ECI conferences and conference functions.
