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.

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.

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.

Transportation from Lisbon to Tomar

Transportation to Tomar: On the weekend, trains depart about every two hours from Lisbon to Tomar at the Oriente train station (Lisboa Oriente).  On weekdays, trains run about once an hour.  The train station is about 3 km from the airport.

To get to Gare do Oriente from the Lisbon International Airport you can go by Metro or Taxi:

  • Metro – Metro trains run every few minutes from 6 am to 1 am.  A one-way ticket is approximately 2-3 EUR.            

Website: http://metro.transporteslisboa.pt/eng/

  • TaxiTaxicabs depart from the front of the airport and the trip takes about 10 minutes. You can purchase a “Taxi Voucher” ticket for the Oriente train station (approximately 25 EUR) inside the airport at the Tourism Information Centre. This option sets an exact price for the trip, but if there is no traffic, then use a regular taxi that would cost between 15-20 EUR. Note: There are usually taxis available at the Departure area of the airport and sometimes the price is cheaper than at the Arrivals area.
  • If you have any questions about these means of travel, you can ask at the “Tourism Information” center at the airport. 
  • The train trip from Lisbon to Tomar takes approximately 2 hours. Upon arrival at the Tomar train station, taxis are available for the one or two kilometer trip to the Hotel Dos Templarios. (For train schedules and tickets visit https://www.cp.pt/StaticFiles/horarios/regional/comboios-regionais-lisboa-tomar.pdf, The cost of a one-way ticket to Tomar is approximately 10 -14 EUR.

If you plan to drive to Tomar, there is free parking at the hotel.  Once in Tomar, follow the hotel signs.  (Our hotel is the major one in the town.)  If you are from the US and have not yet rented a car, try www.autoeurope.com which will allow you to comparison shop.

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.
