About This Conference

Dr. Luis Perez-Maqueda, Co-Chair, and all members of the Organizing Committee welcome your contribution(s) to the third Tomar International Conference on “Electric Field Enhanced Processing of Advanced Materials: Complexities and Opportunities.”

The community stands at cross-roads. The remarkable speed of sintering and phase transformations in complex material-systems with electrical currents, and with high heating rates, have been shown to have great generality. Now, the future lies in (i) basic understanding of these remarkable phenomena, and (ii) their evolution towards application and commercialization. 

The Conference Chair believes that new science and engineering springs from diverse approaches. Results that lie at the fringe can become the springboard for innovation. Therefore, the conference welcomes presentation of ideas that come from different directions, from adjacent fields such as physics, electrochemistry, and artificial intelligence: ideas that are “controversial” and thought provoking.

The Conference invites submissions related to materials synthesis with electrical fields and currents, as well as high heating rates. Topics include but are not limited to: (i) Various materials including ceramics, composites and metals including new materials that are far from equilibrium. (ii) Applications towards functional ceramics, lithium-ion batteries and fuel cells, high entropy oxides, biomedical applications including dental restoration and implants, and graphene related materials.

State of the art methods for characterization with X-rays, electron beams, optical and neutron beams are welcome. Theoretical calculations of defect physics and electronic structure that shed light on the mechanisms of field enhanced methods are encouraged.

The Conference will allow ample time for open discussion of the latest developments (for example touch-free flash sintering). The organizers seek to explore advances in basic science, and real-life applications. We hope that new ideas for manufacturing will emerge from discussions during the Conference.

Chair’s message Nov 18th, 2022

Where we lose ourselves unto the spirit of fellow beings
Where we share and share more, and then more
To achieve grace and
A solitude of a different kind
That remains wrapped in memories
of the mind and the heart

Unique Events: One day Seminar and New Developments

Field Enhanced Processing is a complex methodology. The first day of the Conference will therefore be dedicated to seminars which explain how the experiments are done, the relationship between the microstructural outcomes and the control variables, the measurement of properties influenced by flash, and theory and modeling. There will be four to six lectures with ample time for questions through the day. 

In addition two recent inventions related to enhancing the conductivity of copper and sintering of 3D workpieces, without electrodes, will be discussed.

                        I. Methods: (i) Flash Sintering, (ii) Reactive Flash Sintering (ii) SPS as well as Flash-SPS, (iii) High Heating Rates, (iv) Microwaves

                        II. Experimental Techniques: These can involve (i) Different types and shapes of samples, ranging from powder pressed to single crystals to thin films, (ii) Different control cycles include voltage and current-rate control, (iii) Methods of applying high heating rates, and (iv) Software development.

                        III. Materials: (i) Simple Materials for fundamental investigations, e.g. yttria stabilized zirconia, (ii) Complex, Multicomponent Materials for applications such as solid state electrolytes for fuel cells and Li-ion batteries, high entropy oxides, a new class of structural materials for example high alumina spinel, (iii) Far-from-Equilibrium Materials.

                        IV. Characterization and Properties:  (i) In-Situ and Ex-Situ, (ii) Optical and Electronic Behavior, (iii) X-ray, Electron and Neutron Beams, (iv) Spectroscopy including EELS and Raman, (v) Diffusion, (vi) Mechanical Properties, and (vii) Calorimetry.

                       V. Theory: (i) Interfaces, (ii) Molecular Dynamics and DFT, (iii) Defect Physics, (iv) Ions, Phonons and Electrons.

                      VI. Unusual Phenomena: (i) Plasmas and Magnetic Fields, (ii) Memristors, (iii) Carbon and Graphene, (iv) Metals, (v) Surface Science.

                      VII. Manufacturing: (i) Energy Efficiency, (ii) Scale Up, (iii) Three-Dimensional Manufacturing, (i) Microflash Additive

Abstracts are invited on any of the above and any additional topics. We will attempt to accommodate as many abstracts as we can for oral presentations. Poster presentations will be grouped and synchronized, time wise, with the oral-presentation sessions; therefore, they will be presented continuously throughout the Conference.

Please get ready to participate in this exciting, week-long, event. Welcome to Tomar, Portugal.

Call for Abstracts

Please select a session from the above list (and, if you wish, an alternate session) where you believe your work fits best.

Abstracts (one page maximum) that include specific results and conclusions to allow a scientific assessment of the proposed presentation are invited.  Please prepare your abstract according to this template: docx or doc.

Poster abstract submission deadline:  December 31, 2022

Abstracts of all presentations will be made available to conference participants prior to the start of the conference.

Note: We will attempt to accommodate as many abstracts as we can for oral presentations.  However, only a limited number of oral presentation slots are available and thus all submissions for oral sessions will be considered for both oral and poster presentation. Poster presentations will be grouped and synchronized, timewise, with the topics of the oral presentations; therefore, they will be presented continuously throughout the conference.

Awards will be presented to the top student posters.

Venue Information

Tomar, Portugal

Situated in the geographic center of Portugal, Tomar (about 135 km northeast of Lisbon) was founded by the notorious Knights Templar in 1160. The Templars were part monks, part warriors and plotted crusades from Tomar for centuries. They established the beginnings of the Convento de Cristo, Tomar’s most famous landmark, on a hill overlooking town. The Convento combines architectural styles from the 12th through 17th centuries. An ornate octagonal canopy protects the high altar of the Templo dos Templares, modeled after the Holy Sepulchre in Jerusalem, and the grounds of the convent contain eight cloisters embracing a variety of styles.

Tomar, Portugal

The Templars earned a reputation as ferocious fighters, and won the admiration and trust of both rich and poor. They served as protectors and transporters of Christian kings, power brokers and pilgrims and grew famous as bankers. The Templars acquired great wealth, but made many enemies in the process. Pope Clement V accepted accusations of heresy, blasphemy and sacrilege leveled against the Templars by Philip the Fair, king of France, and many Templars were imprisoned or executed. King Dinis of Portugal allowed them to regroup their forces under the new aegis of the Order of Christ. Prince Henry the Navigator became Administrator after the Templars became the Order of Christ and he used much their wealth to finance his explorations.

Tomar is divided by the River Nabão, the banks of which are dotted with weirs and wheels once used to water vegetable gardens and orchards. The irrigation techniques illustrate the Muslim tradition of hydraulic engineering. Most sights, accommodations and shops lie on the west bank of the river and the lush Parque Mouchão straddles the two banks. The ancient yet functional Ponte Velha (Old Bridge) connects the two. Tomar’s main shopping thoroughfare is rua Serpa Pinto, known locally as Corre Doura. Outlets for folklore, pottery, copperware and wrought iron highlight it. Tascas and bars are scattered throughout the city, with some offering live music.

Hotel dos Templários

Situated near the heart of Tomar’s Old Town, the Hotel dos Templários is the largest hotel in the district. Many rooms offer views of the Convent of Christ and the public areas, including lounges and terrace-view dining rooms, are spacious. The hotel offers room service, laundry, a barbershop, a beauty parlor, a billiards room and baby-sitting. There are wide sun terraces, indoor and outdoor pools, a tennis court and a greenhouse. The hotel also has large gardens. Rooms have air conditioning, private bathrooms, televisions and minibars. Free parking is available.

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.
