Portugueses conquistam Taça da Europa de Bajas

E-waste is one of the fastest growing toxic waste in recent years. Now researchers at the University of Coimbra (UC) have developed and tested a set of new methods that allow us to change this reality and apply 3R (Reduce, Reuse and Recycle) policies in the field of electronics. The results were published in the journal Advanced Materials.

The research, funded by the Carnegie Mellon Portugal (CMU Portugal), Dermotronics and SMART Display WoW projects, represents a new step in the fight against industrial pollution. Currently, the production of e-waste has reached an alarming level of 7 kg per person per year. Only 20% of e-waste is sent for recycling, and only a small percentage of precious metals, mainly gold, are recovered.

Despite the urgency of finding solutions and new forms of production, Mahmoud Tavakoli, the first author of a scientific article, explains that the effective application of 3R in electronics is possible only “if we can demonstrate new production technologies that, on the one hand, depend on elastic, maintainable and recyclable materials and, on the other hand, can compete with existing technologies in terms of pattern resolution, layered implementation, microchip integration, and offline manufacturing.”

This research, which is being carried out at the Institute of Systems and Robotics (ISR) of the Faculty of Electrical Engineering and Computer Engineering (DEEC) of the Faculty of Science and Technology of the University of Coimbra (FCTUC), presents a new architecture for scalable, high-resolution 3R manufacturing, autonomous and electronic devices.

In particular, the scientists have presented a new architecture for soft materials such as conductive composites and substrates that meet 3R requirements; developed offline manufacturing technologies, including high-resolution digital models and one-step microchip welding, as well as ancillary technologies for material and component recycling.

According to an ISR researcher and FCTUC professor, another differentiating factor in this manufacturing process is that it is carried out at room temperature, which is an important step for green electronics: “everything is done at room temperature, including deposition, standardization and soldering of chips. Eliminating the temperature of the sintering process (as is common in printed electronics) and the soldering process significantly reduces energy consumption.”

This research represents a paradigm shift and provides the foundation for the next generation of recyclable electronic devices. However, the methods developed still require further technological development “to achieve the same maturity as current PCB technology, i.e. they lack the necessary maturity, including the desired standardization resolution and the appropriate level of automation for industrial applications.” concludes Mahmoud Tavakoli.

Portuguese historical films will premiere on 29 December.

Method Media Bermuda will present the documentary FABRIC: Portuguese History in Bermuda on Thursday, December 29 at the Underwater Research Institute of Bermuda.

A spokesperson said: “Method Media is proud to bring Bermuda Fabric: Portugal History to Bermuda for its 5th and 6th showing at the Bermuda Underwater Observatory. In November and December 2019, Cloth: A Portuguese Story in Bermuda had four sold-out screenings. Now that Bermuda has reopened after the pandemic, it’s time to bring the film back for at least two screenings.

“There are tickets Ptix.bm For $ 20 – sessions at 15:30 and 18:00. Both screenings will be followed by a short Q&A session.

Director and producer Milton Raboso says, “FABRIC is a definitive account of the Portuguese community in Bermuda and its 151 years of history, but it also places Bermuda, Acors and Portugal in the world history and the events that have fueled those 151 years.

“It took more than 10 years to implement FABRIC. The film was supported by the Minister of Culture, the Government of the Azores and private donors.

“Bermuda Media Method [MMB] Created in 2011 by producer Milton Raposo. MMB has created content for a wide range of clients: Bermuda’s new hospital renovation, reinsurance, travel campaigns, international sports and more. MMB pays special attention to artistic, cultural and historical content.

Maestro de Braga is the first Portuguese in the National Symphony Orchestra of Cuba.

Maestro Filipe Cunha, Artistic Director of the Philharmonic Orchestra of Braga, has been invited to conduct the Cuban National Symphony Orchestra, as announced today.

According to a statement sent by O MINHO, “he will be the first Portuguese conductor to conduct this orchestra in its entire history.”

In addition to this orchestra, the maestro will also work with the Lyceo Mozarteum de la Habana Symphony Orchestra.

The concerts will take place on 4 and 12 March 2023 at the National Theater of Cuba in Havana.

In the words of the maestro, quoted in the statement, “these will be very beautiful concerts with difficult but very complex pieces” and therefore he feels “very motivated”.

From the very beginning, Rachmaninoff’s Piano Concerto No. 2 will be performed by an Italian pianist (Luigi Borzillo), whom the maestro wants to bring to Portugal later this year. In the same concert, Mendelshon’s First Symphony will be performed.

Then, at the second concert, in the company of the Mexican clarinetist Angel Zedillo, he will perform the Louis Sfora Concerto No. 2. In this concert, the maestro also conducts Tchaikovsky’s Fifth Symphony.

“This is an international recognition of my work. An invitation that I accept with humility and great responsibility. I was surprised to learn that I would be the first Portuguese member of the Cuban National Symphony Orchestra. This is a very great honor,” the maestro said in a statement.

“I take with me the name of the city of Braga and Portugal with all the responsibility that goes with it, and I hope to do a good job there, leaving a good image and putting on great concerts. These will be very special concerts because, in addition to performing pieces that I love, especially Rachmaninov and Tchaikovsky, I will be directing two wonderful soloists who are also my friends. It will be very beautiful,” concludes Filipe Cunha.
