Luis Araneda, member of the Optoelectronics Division and Pablo Henríquez, for Nondestructive Characterization of Materials, were selected from 1,333 applicants to the Masters Fellowships competition in Chile. Both, the first one, memoirist of Civil Engineering Electronics, led by Dr. Miguel Figueroa and the second one, degree in physics sciences and works with Dr. Renato Saavedra, share interdisciplinary approach given by their teachers in CEFOP.
The design of a detector plate of coincidences of photons and of an implantable muscle stimulator, for improving spinal cord injuries were two draft who Luis Araneda was part of. He considers the experiences were transcendent in its work and he believes his participation in them was valued at the time of receiving the scholarship. “I worked on both projects last year. Now I’m about to submit my memory of title, in some of these coming months. “
At first he were not sure what to do at the end of his career, then his teacher guide, the researcher Miguel Figueroa, insisted him that he apply for the Masters and scholarships. “Thanks to this insistence, I was convinced I wanted to continue to research and specialization. I was very confused at first. Now I focus on studying, and I applied for an internship in Canada, which could materialize in the second half of 2013”, he said.
Last year Pablo Henríquez joined to CEFOP through an internship with Dr. Renato Saavedra, and he worked on photoacoustic spectroscopy experiments. Today, he is focused on thermal lens experiments. “The thermal lens helps determine the concentration of chemical compounds in a complex. For example, a compound may bring many elements, and we determine what concentration of this element contains the complex”. Laser chemical analysis can be applied in the areas of food, medicine, could develop photoreactive and study of materials.
Pablo has a degree in Physics, and still has another year to finish his bachelor on physical engineering. “I want to do my undergraduate thesis with my master’s thesis in the area that I’m currently working on. Hopefully, with the guidance of Professor Renato”, he said. “He is very supportive guide to us in that we must do. He is very clear with what he says and that makes things go good”, he added.
Getting involved in issues from other areas is a feature that were highlighted by both students. “In addition to learning a little Portuguese, has been good and we shared a lot. I did not expect a majoy like this, because I thought that studying Electronics would be more specific and only later would be interdisciplinary experiences, but not while”, Luis reflected. For example, in relation to experiment photon coincidence, Luis admitted it was something totally new, and only after an explanation by the others researchers, doctors Guilherme Barreto Xavier, Gustavo Moreira Lima and Wallon Andersen Tadaiesky, he could understand.
“In this experiment we developed a plate able to detect and count coincidences in one or more channels of the detector, which is four. We designed the entire detector and also the graphical interface from the computer, so that functioned simultaneously. That means that the detector can not function without the computer. That, in a way, complicates things to be dependent both parties, but allowed us to simplify the design we did in the plate, which allowed it faster”, said Luis.
On the other hand, Pablo has had the opportunity to interact with faculty from the School of Chemistry, who provide samples of thermo-optical laboratory in which he works. “The thermal lens is an analytical technique for determining nonlinear optical properties of materials. We are working with Professor Cesar Soto, who brings us the samples for analysis. He provides liquid samples of chemical compounds, we analyzed them with a set-up optical and we determinated nonlinear optical properties as the refractive index and absorption of the sample”, he said.
For now, Luis explained that he has not thought about what to base his master’s thesis, “but I think it will relate to the objectives of the laboratory, working with infrared cameras, whether surveillance video processing, or hyperspectral cameras to detect the maturity of the fruit, and automate certain industrial processes. ”Likewise Paul expects to complete either the Master in your area and then pursue a PhD. “Then I’ll see what follow doctorate and where I would like abroad. Germany is strong in the development of physical and Chile is starting yet CEFOP I value that good research is done, “he said.
