At the beginning of his second week in Korea, Alejandro was introduced to the main lab area he would later be working in as well as to electrode fabrication devices/technologies (reintroduced, in the case of photolithography). Choi walked him through the processes of analyzing/evaluating/adjusting electrodes by using computer programs, several chemical solutions, and iridium oxide electrodeposition; he will be using these processes in the final stages of his project. Unfortunately, he was unable to do anything else concerning them this week, as he had no electrodes to work with. In the meantime, he was assigned relevant academic papers to read and report on.
On his second Saturday in Seoul, Alejandro went to Journey, a burger place near his house, with roommates William and Peter. He relaxed at the house for the rest of the day, only going out again for KBBQ dinner. Sunday was a much more active day; he took his first trip to the Yeouido area (an area he had wanted to see since before the trip). He ate lunch at a mall near the Yeouido metro station and walked to Yeouido Hangang Park, where he rented a bike for a one-hour ride. He then returned to Gwanak-gu for dinner and dessert with the four other IRiKA students. On Monday, Alejandro (and the other students) participated in the KITECH tour with his LSU mentor, Dr. Jin-Woo Choi (Dr. Choi’s presence was a pleasant surprise!). The tour itself was pretty interesting, consisting of some intro videos and a tour of one of the KITECH laboratories, in which inkjet printing was demonstrated. After lunch with Dr. Choi, the tour guides, and the other students, Alejandro returned to his home before making a surprise return to Yeouido (unfortunately he’d left his Louisiana ID card behind, using it as deposit when he used the bike rental service the day before). On Tuesday evening, he played basketball and table tennis with his lab group after work; he then freshened up and rejoined them for a chicken and beer dinner, which was delicious (even the beer!).
