• The candidacy of the renowned electrochemist for the highest scientific award of the country is supported by our University and different associations and representatives of the national and international scientific world.

With the support of Universidad de Santiago de Chile, through its highest authority, President Juan Manuel Zolezzi, the candidacy application of the University’s renowned researcher was submitted last week. He has been recognized by his peers and has been honored by international scientific societies that validate the experience and contributions made by this researcher of the Faculty of Chemistry and Biology.

The National Award is the maximum prize given by the State to acknowledge the work made by Chileans who stand out by their excellence, creativity and significant contribution to culture and the development of different areas of knowledge and the arts.

In the University’s scientific community nobody has been awarded this prize yet; for this reason, Maritza Páez and Jorge Pavez, both academics at the Faculty of Chemistry and Biology, did not hesitate to promote Doctor José Zagal’s nomination to the National Award of Natural Sciences 2014, who has been honored both in Chile and abroad.

Contribution to education

Jorge Pavez, a researcher, and Maritza Páez, the Director of the Department of Chemistry of Materials of Universidad de Santiago, were both among Dr. Zagal’s students and they highlight his enormous contribution to teaching, as well as his scientific career. At an academic level, they stress the work he has done directing Master’s degree and doctoral dissertations.

“Dr. Zagal’s contribution is notable, because it has positioned Universidad de Santiago and the country in the electrochemistry research world scene,” Dr. Pavez said. He added that Dr. Zagal’s nomination is based on his career throughout these years contributing to this field, both at a scientific and at an educational level, at training new generations.”

Also, professor Pavez said: “His contribution to electrochemistry has gone beyond the country’s borders and the region. Proofs of this are the two international prizes that were awarded to him this year by the world most renowned scientific societies in this field: the Electrochemical Society (ECS), in the United States, and the International Society of Electrochemistry (ISE), in Europe, that record the highest-impact publications on electrochemistry.”

In April and June, both societies, ECS and ISE, sent Dr. Zagal letters of recognition appointing him “Fellow”, “for his exceptional contribution to electrochemistry” and “scientific achievements.” The ISE has scheduled its awarding ceremony for September, during its annual meeting in Switzerland, while the ECS has scheduled its ceremony for October, during its bi-annual meeting that will be held in Mexico.

Valuable work

According to the candidate for the National Award of Natural Sciences, this year 2014 has been especially meaningful due to the recognition of his work. On the one hand, he received the recognition of the societies mentioned above, and on the other, he received the support from the University and his peers.

“Curiously, this year I have been honored by two international associations and I think this is important, because they are external organizations that recognize that, at Universidad de Santiago, our work is valuable,” Dr. Zagal said.

In addition, renowned scientists of other universities support him too and so do the editors of noted international publications in which he is part of the editorial board, like the Journal of Solid State Electrochemistry, Electrochemistry Communications, International Journal of Electrochemistry, Electrocatalysis, International Journal of Biotechnology & Biochemistry, ISRN Electrochemistry, Electrochemistry Communications, Journal of the Serbian Chemical Society and Electrochemical Energy Technology.

At present, Dr. Zagal is working in two lines of research at Universidad de Santiago: The development of electrodes for energy conversion systems and the development of sensors for detecting substances in fluids.

“There are prominent scientists at our University, but none of them has been honored with a National Award and I believe that sometime one of them should be awarded a prize like this; this would be very important for the prestige of our University, because it is one of the universities that conducts more research in Chile,” Dr. Zagal said.

The jury that will decide on the National Award 2014 (according to Law 19.169) is made up by the Minister of Education, Nicolás Eyzaguirre; the President of Universidad de Chile, Ennio Vivaldi; the President of the Chilean Academy of Science of Instituto Chile, Juan Alfonso Asenjo; the President of Universidad de Antofagasta (on behalf of the CRUCH), Alberto Loyola Morales; and the previous award winner (2012), Bernabé Santelices González

•  Carolina Aliaga, professor at the Department of Environmental Sciences of the Faculty of Chemistry and Biology of Universidad de Santiago was appointed representative in Latin America by her peers during the last meeting of the Inter-American Photochemical Society. “It is a recognition for the work we have done at the university, the place of birth of Photochemistry in our continent, where several generations have been trained in this field,” she said.

During the 25^th Meeting of the Inter-American Photochemical Society (I-APS), Carolina Aliaga, professor at the Department of Environmental Sciences of the Faculty of Chemistry and Biology of Universidad de Santiago, was appointed representative of this society in Latin America. She is the first Chilean to hold this position.

The meeting was held in Chile, for the first time, between May 24^th-27^th, at the Centro de Extensión of Universidad Católica, in Santiago. Carolina Aliaga and Alexis Aspee, both professors at Universidad de Santiago, were part of the organizing committee.

“All the participants were so glad about the high level of the meeting. It was beyond their expectations,” professor Aliaga said. “They all appreciated the level of the works presented.”

The organizing committee had the collaboration of researchers at Universidad Católica, Universidad de Chile and Universidad Andrés Bello. More than 150 people attended the activity: undergraduate and graduate students, professors and researchers from USA, Spain, Germany and Argentina, among other countries.

The meeting, which focal point was Photochemistry, included works related to bioenergy, nanocatalysis, photoluminescence, photodynamic therapies, basic chemistry and others.

“I feel glad because everyone can contribute to science development through cooperation and generate new collaboration opportunities among researchers,” professor Aliaga said. “This is a recognition for the work we have done at the university, the place of birth of Photochemistry in our continent, where several generations have been trained in this field,” she added.

Regarding her new position, she will act on behalf of the association suggesting speakers for future meetings, awards for experienced researchers and young researchers, among others.

“I think the first challenge I have to face is to position the names of researchers who are just starting in this field and support good students,” she said.

The Inter-American Photochemical Society has more than 600 members in academia, industry, and government throughout North and South America. It promotes collaborative networks among its members, so that they can share their experiences and knowledge.

• Professor Osvaldo García was invited to give a presentation on an organizational self-observation tool, called CLEHES©, to postdoctoral students of Takashi Ikegami Laboratory, an institution specialized in the field of artificial life, at University of Tokyo.

More than ten years ago, Osvaldo García, professor at the Department of Industrial Engineering of Universidad de Santiago, started to develop CLEHES, a tool that intends the individual to generate learning, both at a personal level and at workl, through self-observation and the observation of interactions among human beings and their constituting networks, developing a diagnosis and an organizational design through Body, Language, Emotion, History, Eros and Silence (CLEHES©, its acronym in Spanish).

The contribution made by the course given by professor García, called Human Reengineering for Action (Rihpla, its acronym in Spanish), of the Department of Industrial Engineering, together with the academic prominence and prestige of CLEHES, made the publication of this innovative tool to be among the 100 most important international scientific publications in the field. In turn, it called the attention of different institutions that were interested in this emerging and effective technology.

For this reason, the professor Takashi Ikegami´s artificial life laboratory at the renowned University of Tokyo, in Japan, contacted professor García and invited him to give a presentation in September 2013 to graduate students at that Asian institution.

Professor García explained that, at Takashi Ikegami Laboratory, where the latest advances in robotics are being developed, they had a closed seminar for postdoctoral students and, besides, they explored the applications of CLEHES to the field of artificial life.”

“Students there made an effort to evaluate what changes could be made to apply some aspects of CLEHES´ structural dynamics to robot building,” García said. “We even talked about the possibility of generating a CLEHES-Robotics tool in collaboration with our University,” he added.

Professor García, an academic at Universidad de Santiago, stressed that, in Japan, robot building “is not approached through aggressive or merely recreational policies. It is considered a contribution to society, for example, to help senior citizens.” Therefore, the social self-observation tool CLEHES would be very useful.

Professor García showed himself satisfied with the new possibilities of internationalization and collaborative work with Japanese specialists opened by the research during the Rihpla course and CLEHES, and besides, he highlighted the concept of applied “ortho-discipline”, that is to say, to respect the autonomy of the different specialists involved in a collaborative project.

“In the Japanese culture, it takes time to establish collaborative relationships, but even so, we were able to forge significant links with them and also with the Japanese Embassy, where entrepreneurship and innovation are developing valuable bilateral ties,” professor García concluded.

CLEHES used by young researchers

Susana Gómez, who is doing her dissertation on diagnosis for her Master´s degree in Engineering Sciences using CLEHES technology, said that this innovative tool has been very useful to young students who pursue a specialization in management solutions.

“The networks created due to the international prominence of CLEHES have been amazing,” she said.

“This is a really new tool for management that is gaining strength and is being put into practice. Japanese specialists have the theoretical knowledge and the laboratories, but they have not put this technology into practice. Here in Chile, we have taken it to companies and schools and we have also applied it in our academic unit both in undergraduate and graduate students,” she said

For his part, Roberto Álvarez, a student who obtained his Master´s degree in Engineering Sciences by doing his dissertation using CLEHES to solve organizational problems said: “This management tool has been very helpful for my professional career and for working at big companies.”

“Besides, studying and applying this meta-discipline has helped us to open opportunities and to differentiate ourselves from other universities’ students,” he concluded.

• This year, professor Zagal, academic at the Faculty of Chemistry and Biology, was also honored by the International Society of Electrochemistry of Europe and was a candidate for the National Award of Natural Sciences.

Scientists from all over the world met in Cancun, Mexico, to hold the 226^th version of the bi-annual meeting of the Electrochemical Society (ECS), a scientific American society founded in 1902 that gathers together more than 8 thousand 700 scientists in the field of electrochemistry.

The meeting was attended by more than 2 thousand people and included several activities, among which it is worth to mention the 2014 ECS Class Fellow award ceremony. Fifteen international scientists were appointed Fellows and one of them was Dr. José Zagal, researcher at the Faculty of Chemistry and Biology of Universidad de Santiago de Chile. He was honored for his contribution to the progress of science and technology, his leadership in the field of electrochemistry and his active membership in the ECS. He is the first active researcher in a Latin American country to be awarded this honor.

“It is very gratifying to me to be awarded this honor because our work is being recognized by an international scientific society founded and based in the United States, with more than 100 years of history and that has gathered renowned scientists and innovators in the world, like Thomas Edison, for example,” Dr. Zagal said.

According to Dr. Zagal, the honor he was awarded – that can be added to the one he received this year from the International Society of Electrochemistry of Europe-, “confirms that we are being recognized abroad,” making reference to the strong research groups in the field of electrochemistry that work at the Faculty of Chemistry and Biology of Universidad de Santiago.

“I speak in plural, because my achievements in this field are the result of many years working with excellent colleagues and collaborators and outstanding students. This award particularly encourages me to continue giving my students my best, with devotion and eagerness, and promoting our University research work around the world,” he added.

Finally, Dr. Zagal thanked the Faculty of Chemistry and Biology and Universidad de Santiago for their unconditional support during his 41 years of work at this institution.

 A research team led by Dr Claudio Vásquez Guzmán, professor at the Department of Biology of Universidad de Santiago de Chile, proved that Antarctic bacteria are able to resist tellurium when they are exposed to oxidative stress.

Dr Claudio Vásquez, professor at the Department of Biology of Universidad de Santiago de Chile, together with his research team, proved that Antarctic bacteria are able to resist tellurium when they are exposed to oxidative stress. 

Tellurium (Te) is one of the many elements in the Periodic Table. It belongs to the same chemical family as oxygen, sulfur, and selenium, which are considered essential to life. However, until now, we still do not know if this element has any biological function. For this reason, the research team of the Laboratory of Molecular Microbiology of the Faculty of Chemistry and Biology of Universidad de Santiago de Chile, led by Dr Claudio Vásquez, has studied this element for years, trying to understand the molecular basis of its toxicity.

Since 2013, Dr Vásquez and Dr José Manuel Pérez, of Universidad Andrés Bello, have worked together in the Regular Fondecyt Project N° 1130362 “Tellurite-resistant Antarctic bacteria: Unveiling new toxicant resistance mechanisms,” which was recently completed.

“The hypothesis of our project was the following: As bacteria living in the Antarctica are resistant and adapted to oxidative stress, they should be resistant to tellurite. The idea was to find super-resistant bacteria that could help to establish the usefulness of tellurium to the cell,” Dr Vásquez explained.

The idea of the project came from the observation of isolated samples collected from different places in the Chilean Antarctica. They visited the Prat and Escudero Antarctic Bases, Deception Island and Fildes Peninsula and travelled on the Almirante Óscar Viel ice-breaker of the Chilean Army, where they were able to find, isolate and describe microorganisms resistant to oxidative stress and tellurite.

Tellurium is primarily used in the manufacturing of solar cells. According to Dr Vásquez, “It is an essential part of photoelectric cells that capture sunlight and transform it into electricity.” This is the reason why this element is a potential source of energy. “Now we need to create a system to remove tellurium from the environment, because it is very scarce,” he added.

In Chile, tellurium is produced as a byproduct of the copper refining process. It settles as anode slime and it is not recovered. “If we store it and control it well, we could contribute to prevent its potentially toxic effect on the flora and fauna,” he said.

Dr Vásquez concluded by saying that Universidad de Santiago has been really important during the conduct of this study for its support and constant collaboration.

• In recognition of his extensive career in the area of electrochemistry, Dr. José Zagal, professor at the Department of Chemistry of Materials, was invited to be part of the editorial board of Electrochemistry Communications, an international journal with the higher impact index in its field.

Dr. José Zagal, professor at the Department of Chemistry of Materials of our university, was selected to be part of the editorial board of Electrochemistry Communications, the renowned scientific journal partnered with Elsevier that has the higher impact index in the field of electrochemistry.

In a conversation with UdeSantiago al Día, the academic said that he understood his inclusion in the board as “recognition of my work over many years; but most important, the recognition of a work that has mainly been done by a team.”

Professor Zagal has a vast experience in the scientific research field, particularly in the study of oxygen and reactivity. He started to work at Universidad de Santiago 40 years ago and he has kept on publishing specialized articles in his field of interest since then.

Besides, he has been part of editorial boards of different scientific journals, like the International Journal of Electrochemistry of Hindawi Publishing Corporation, since 2011 and the International Journal of Biotechnology & Biochemistry (IJBB), since 2012.

Zagal said that it is very important that both students and academics produce publications in their fields and get involved in different creative processes “to contribute not only to this University’s development but to all the country.”

“I think that it is necessary that students in any program should take part in creative and practical processes, that is to say, they should get involved in laboratory work since their first years at the university, so that they produce new knowledge that can reach most of the people through renowned publications,” he said.

“Publishing research results is essential. When you make public the work you do, your work becomes recognized in that field and, at the same time, you spread new knowledge,” he added.

For this reason, professor Zagal expects that his role at the Electrochemistry Communications’ editorial board means a contribution to the promotion of sciences and to the better positioning of Universidad de Santiago de Chile.

“You stay at this university because you love it and not for the money. Many researchers here might well be working at private sector companies, but they stay here because they feel a real bond with this institution,” he said.

“For the love that I have for this University, I expect that my inclusion in the editorial board will benefit the institution and will contribute to spread knowledge among society,” Dr. Zagal concluded.

• The scientific committee of the V Latin American Congress of Mathematicians recognized professor Navas for his scientific contribution to the region in areas like geometry, dynamical systems, algebra and group theory. The activity was organized by the Unión Matemática de América Latina y el Caribe (UMALCA) and it was held in Barranquilla, Colombia.

Dr Andrés Navas, professor at the Department of Mathematics and Computer Science of Universidad de Santiago de Chile, was awarded the UMALCA 2016 Prize during a ceremony in the V Latin American Congress of Mathematicians (CLAM, in Spanish) organized by the Colombian Society of Mathematics (SCM, in Spanish) and Universidad del Norte de Barranquilla, Colombia.

The prize was created in 2000 to honor young mathematicians working in Latin America and to recognize and promote their scientific contributions. After receiving the award, Dr Navas gave a presentation in a plenary session of the congress, which is considered the most important meeting of mathematicians in the region. The 40-year-old professor gave the presentation “Propiedades asintóticas de redes del plano”.

Henrique Bursztyn (IMPA, Brasil), Pablo Shmerkin (Universidad Torcuato di Tella, Argentina) y Robert Morris (IMPA, Brasil) were also awarded prizes for their contributions.

Recognition for scientific research

Dr Navas, who is currently the president of the Mathematics Society of Chile (SOMACHI, in Spanish), said that this award is a recognition for his scientific work; it is the highest recognition that a mathematician working in Latin America may expect.

He thinks that the prize will contribute to the positioning of Universidad de Santiago and the Department of Mathematics in the local and Latin American context.

“It is a significant step for the University and the Department, which has grown very much in the past few years. It will make us more visible at a Latin American level,” he said.

He thinks that another factor that contributed to him being awarded the prize was the publication of his doctoral dissertation “Groups of Circle Diffeomorphisms” (2011) in USA.

 “The University of Chicago Press published my doctoral dissertation as a book, a milestone in the Latin American context, because it was translated from a former publication in Peru and Brazil,” Dr Navas explained.

Promoting Mathematics

In the national context, Dr Navas expects his prize becomes a turning point so that the State creates an institute devoted to fundamental Mathematics.

“We do not have an institute like this in Chile and it would be similar to the National Institute for Pure and Applied Mathematics (IMPA) of Brazil. I think we already have all the human potential to do it, but we need the relevant policy making,” he said. “We really need something like this in our country.”

• Dr. Maximiliano Salinas, researcher at the Department of History, was invited to Universidad de Concepción’s Summer School, where he talked about the meaning of festivities as part of the historical process of a country. “During festivities, people reencounter the essence of their human, spiritual and collective experience,” he stressed.

“Celebration: Dionysus’ times come back to us” was the name of the presentation given by Dr. Maximiliano Salinas, professor at the Department of History of Universidad de Santiago, to the Universidad de Concepción’s community in the inauguration of this university’s 2014 Summer School.

On this occasion, the activity that has been carried out uninterruptedly for more than a decade, has the topic “Festivities: the art of celebrating” as its central subject, a subject to which our University’s researcher can considerably contribute, as he is an expert in popular culture history.

Regarding the role that celebrations play in local identity, the academic says that in all cultures and civilizations, festivities are an integral dimension of people’s lives, because during celebrations people reencounter the essence of their human, spiritual and collective experience.

“In the case of Chilean history, festivities, like all life dimensions, are crossed by contradictions stemming from the colonial times. Indigenous peoples were prodigiously inclined to celebrating. The colonial times order, the European enlightened absolutism, tried to control and restrain that spirit,” Dr. Salinas explained.

However, according to Dr. Salinas, that was not possible, “because the celebration legacy was passed to mestizo peoples and it got mixed with the festive influences from Spain and Africa that left us the cueca, the dance of the Chilean celebrations. Although colonial aspirations- coercive and repressive ones- are replicated until today, festivities will always represent the extension of our humanity and our spirit. The student protests nowadays have undeniably included a festive component that is part of our more permanent culture.”

When asked how the military dictatorship affected this characteristic feature of Chilean culture, Dr. Salinas said that this process can be understood as a systematic effort to extinguish the spirit of popular celebrations, indigenous or mestizo festivities in the country. “Their ambition to impose manu militari, the neoliberal discipline was, basically, an aggressive aspiration to finish with community life and the merry communal living among Chilean people. The idea was to subdue us and turn us into consumerist, scared and indebted individuals,” he said.

According to the expert, a cultural reflection about our identity as a nation is a challenge today, especially in a context in which some sectors of our society express the need of having a new Constitution. “In this sense, it is essential to have a reflection and a discussion about celebrations, as they are part of our original biological and spiritual make-up as a country. This is much more deciding, lively and deep than legal texts or the discussion among constitutional ‘experts’,” he said.

Finally, Dr. Salinas thinks that we should recover the original religious spirit of celebrations, that is to say, the spirit reflected by Dionysus, the god of cosmic harmony, of beautiful lush vegetation; the god of the joy of a nude and equal community without disguises and without ambitious aspirations. “We have to recover the spirit that indigenous peoples had and cultivated for thousand of years and that mestizo peoples legitimately inherited. In that spirit, we should find the delighting value given by the historical vindications of our societies during the 19th and 20th centuries. This was especially expressed during the Government of the Popular Unity, in a much more decisive way than in any other particular political circumstance. There it lies the deepest mysticism of festivities,” he said.

• Alonso Arellano, an expert in geophysics and geology, explains that, due to the type of lava, the potential following events should not be catastrophic. “We may expect stronger eruptions to last for weeks or months.” 
• He says that most of the gas column will pass to the Argentinean territory, just like on other occasions.
• “The alert actions taken for warning people have been adequate,” he says. He suggests people to be alert, because “there is always the possibility of fissures in the volcanic cone and lava could flow in other directions.”

 

After the Villarrica volcano’s eruption early in the morning on March 03rd, an area of 10 kilometre radius around the mountain was restricted. The area includes the Pucón, Villarrica and Panguipulli communities, where the red alert prevailed until yesterday evening. In the areas outside this radius, the Onemi national emergency office issued yellow alert.

Alonso Arellano, professor at the Department of Metallurgical Engineering and an expert in geophysics and geology, considers the actions taken as adequate. Dr Arellano has worked on the study and analysis of predictive models for volcanoes.

“The actions taken are in the scope of what is expected in alert situations and they should not lead to complications,” he says.

He says that the places over which lava flows have been studied and identified, “however, there is always the possibility of fissures in the volcanic cone and lava could flow in other directions,” so he asks people to be alert.

“We have to live with volcanoes and some of their properties are unpredictable. We cannot say that everything is under control, but the alert actions have been suitable, because the country has enough experience,” he explains.

Known behaviour

The expert explains that the basaltic magma typical of the Villarrica volcano is made up of dark- to- intermediate-coloured minerals like pyroxene, olivine, some iron and amphiboles, which are rocks with higher melting points. This means that gases can flow more easily in comparison with other thicker or less liquid types of magma, avoiding gas accumulation and pressure build-up inside the volcanic cone.

“Due to the type of lava, the volcano’s behaviour should be similar to the one in previous eruptions, with a constantly increasing and decreasing activity. If the magma flows over the volcano slopes, it will depend on its pressure and on how it goes up the vent,” he said.

Professor Arellano says that these events could continue. “We may expect stronger eruptions for weeks or months.” 

With regards to the risks to people, professor Arellano explains that besides the risk posed by lava itself, ashes could be harmful. However, he says that most of the gas column will pass to the Argentinean territory, just like on other occasions. 

Professor Arellano holds a PhD in Engineering Sciences with a major in geophysics, geology and geothermal science.
