Mixed Conducting and Nonstoichiometric Compounds VIII

November 3 – 7, 2024
Tainan, Taiwan

About This Conference

The aim of this conference is to bring together scientists from diverse disciplines, who are working on mixed conducting and nonstoichiometric compounds across crystalline, amorphous, and polymeric materials. Traditionally, the effects of stoichiometry deviations have been studied by those looking to understand and control the electrical, mechanical, optical and thermal properties. The technological uses for such materials are diverse, including energy storage, catalytic transformation, separations, computing, and bioelectronics.

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. Beyond inorganic compounds, mixed conductivity and nonstoichiometry have been recognized in polymers as well as in mixed organic-inorganic crystals.

Given the diverse fields of applications, it is clear that a truly international conference devoted specifically to compounds that display nonstoichiometry and mixed conductivity 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 1980’s. 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, but the emphasis will be on nonstoichiometric compounds.

The last conference “Nonstoichiometric Compounds” in Miyazaki, Japan, in March 2019, was again very successful, and it was determined that the next meeting will be held in a country in which the conference had not been held previously, with the goal to further expand participation. With an increasing demand for advances nonstoichiometric materials in various fields of science and engineering we expect to run an attractive conference.

The conference will consist of topical sessions on:

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

Venue Information

Chihkan Tower, Tainan

Tainan, on Taiwan’s southwest coast, was the island’s capital from 1683–1887 under the Qing dynasty. The climate is warm year-round.  Today it’s known for its centuries-old fortresses and temples and is known as the – Capital of Taiwan. One of its most famous sites is Chihkan Tower, an 18th-century Chinese complex with gardens, intricately carved towers and a temple erected on the foundations of Fort Provintia, a Dutch outpost dating to the mid-1600s.  It is the oldest city on the island and also commonly known as the “Capital City” for its over 200 years of history as the capital of Taiwan under Koxinga and later Qing rule. Tainan’s complex history of comebacks, redefinitions and renewals inspired its popular nickname “the Phoenix City”.  It is famous for its diversity and density of temples and shrines.  Some of them are the only of its kind on Taiwan.  There are seven Buddhist temples and eight Taoist shrines.  

Tainan Confucius Temple

The Tainan Confucius Temple is listed as a national historic site and was built in 1665.  It is Taiwan’s oldest Confucius temple and became the place of education for cultivating talents, signifying the establishment of Taiwan’s formal education.

Grand Mazu Temple, Tainan

Tainan Grand Mazu Temple is Taiwan’s first officially built Mazu Temple. Mazu is a Chinese sea goddess and is the deified form of Lin Moniang, a shamaness from Fujian who is said to have lived in the late 10th century.  After her death, she became revered as a deity of Chinese seafarers, including fishermen and sailors. The grand Mazu Temple, which has been protecting Tainan for more than a hundred years, is the center of belief for the people of Tainan. Today, Tainan Grand Mazu Temple is also a national historic site. 

Caoshan Moon World

An interesting geological site is Caoshan Moon World at Zuozhen District, Tainan City.  It is a terrain of slate-grey mudstone that consists of sandstone and shale. It connects with the nearby mudstone badlands to form a landscape of mostly chalk soil. Highly alkaline chalk soil makes it nearly impossible for vegetation to grow here. It feels as hard as rock when it is dry and becomes muddy after rain. The rain washes and cuts the surface of the terrain, leaving geological features such as half-sides of mountains, deep valleys, winding streams. Only plants with the greatest vitality are able to survive this badland. Apart from barren land, there are only thorny bamboos and weeds seen within the nearly one thousand hectors of area, thus forming the most typical terrain of moon world.  It is a popular place for appreciating the setting sun. 

The connected peaks of chalk soil hills that pile up one layer beyond another and the boundless and majestic terrain of the Moon World are a unique geographic landscape.

In addition to its historic and cultural attractions, Tainan boasts a stunning natural landscape and well-known agricultural and fishery products and cuisine.  Taipan’s fresh and sweet flavors originate from its thriving sugar industry in the early days.  Some of the favorite foods are the clear and sweet beef soup and the sweet and aromatic rice cake.  Tainan City is the home of numerous fruits, where fresh seasonal fruits are available throughout the year, including mangoes in summer and strawberries in winter. Fruit desserts taken with ice desserts, tea and cake, are not to be missed delicacies while traveling in Tainan.

Chimei Museum

The Chimei Museum is a private museum whose collection is divided into five categories: Fine arts (including painting, sculpture, decorative arts and period furniture); Musical instrumentsNatural history and fossilsArms and armorAntiquities and artifacts. The museum is known for housing the world’s largest violin collection and for its significant collections of ancient weapons and sculptures.

Guandi (Guan Gong) Temple

The oldest and most impressive temple in Taiwan is dedicated to Guandi (Guan Gong), a Han-dynasty general deified as the God of War.  He is the patron of warriors and those who live by a code of honor.  The temple’s overall structure was established in 1690 although much splendid artwork and many historically valuable objects have been added over the years.  The long, deep-rose-colored walls of this temple have always been one of its highlights.

Night Market, Taiwan

Night markets in Taiwan are an absolute institution and an important part of the culture for many centuries.  Night markets in Tainan in southern Taiwan are arguably some of the best and most original and are famous throughout the country.  They’re located outside of the city center and are only open on one or possibly a few days per week and are located in massive pedestrian-only areas (usually large parking lots) where stalls are set up temporarily at night.  As Tainan is considered to be the food capital of Taiwan, the night markets are the best way to experience Tainan-style Taiwanese street food.  The most famous night markets: Garden (also called Flower) with approximately 400 stalls; Ta-Tung (also spelled Dadong) with about 350 stalls; Wusheng (250 stalls); Xiaobei Chenggong; and Xin Yong Hua. Each is unique in its own way.  In addition to food, there are games and souvenirs.


Your trip from Taipei will be a total of 64 miles (102 km and the cost of travel will depend on the means of transport.  The quickest option but most expensive option is the high-speed rail (1 hour and 45 minutes – as much as US$115 in late 2023).  There are also trains that take approximately 3 hours at a cost of approximately US$35.  The least expensive option is the bus (approximately US$16) and that takes longer as it makes multiple stops along the way.  There are approximately 31 trains each day. Their website provides information in Chinese, Japanese and English.

The regular railway takes approximately 3 hours.  Tainan has direct flights to and from Hong Kong and Osaka.

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. Over 2000 interdisciplinary conferences have been held.

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.
