Why did you choose ITMO University?
There were different reasons. First of all, ITMO University has always been popular among Chinese scientists as a university that focuses on optics. When Chinese People's Republic was founded, the new government focused on developing science and applied research. Many of the young people went to USSR to study at its universities, including LITMO (the former name of ITMO University — Ed.). Upon returning to China, they became renowned scientists, who've founded many scientific schools in my country. Secondly, the International Research Center for Nanophotonics and Metamaterials has a strong team of scientists which I really wanted to join. My third reason was personal — my girlfriend went to study in Saint Petersburg, so I followed her here; as of now, we are married.
Why did you focus on wireless power transfer technologies?
Some ten years ago Apple presented their first touchscreen smartphone. Then, its full battery charge was enough for a week. A lot has changed since, as consumers demand more functions in their devices. Today, a smartphone is not just some means of communication, but a lot more. Still, all the new functions come with a price. Now, the battery life of a smartphone is no more than two days.Scientists develop new technologies for accumulating and storing energy, and thus wireless power transfer is a most promising technology.
How can use of nanomaterials improve this technology?
As of now, there were no significant breakthroughs in the field of increasing battery's efficiency, but many companies develop resonance charging. The first scientific report on this topic was published in 2007 and explained how to power a 60 W lamp wirelessly from a 2 meter distance. Those scientists used metal coils, and I study how to replace metal with ceramics. Using this material allows decreasing energy losses at charging and thus increasing the processes efficiency. We already have a prototype to work with.
Do you plan on staying at ITMO after you get your PhD?
I can't say for sure. This is my third year at ITMO University, and I'll spend another three years here before I finish my thesis. I really like working here: my colleagues are good professionals and really friendly people. I already know everyone, and I really enjoy the atmosphere at my workplace. What's more, I've always noticed that the department's potential constantly grows, and its staff always looks for new, more complex tasks. In 2013, when I just arrived here, ITMO University got the 5−100 program grant, and during the last three years the university has made huge steps forward. I am proud to be part of these changes, to be part of this team. That’s why continuing my scientific career in Russia may be a great option for me. Still, I haven't decided on it yet.
Tell us, what was most difficult for you when you first came to Saint Petersburg?
At first, I didn't know Russian. It wasn't a problem at the university, as everyone speaks English there, but Russian is essential for everything else. For instance, I couldn't talk to cashiers at supermarkets. So, I had no choice but to learn it by speaking to the locals. Also, I really wanted to join conversations between students, be a part of their community. The students from my group were a great help, and when I became a Research student, I was told that I will have to defend my thesis in both English and Russian. So, I took up a course in Russian.
Was there anything confusing or misleading about life in Russia?
I don't know if this is a cultural thing, but several times strangers on the street invited me to have a drink with them. First time, I was even scared: it was a cold winter evening, I was alone, and some stranger invited me to drink alcohol with him. Then, after a few times, I understood that such people have no ill will, they just seek company. I believe that it is ok. Still, I never joined them, as I don't drink myself.
What do you miss here in Russia most?
Well, I sure miss my relatives. During these three years, I've only been to China twice, as the tickets are really expensive. Also, I miss Chinese food. Me and my wife, we try making our food ourselves, and when we can't, we go out to eat sushi. Yet, I've still learned how to prepare borsch — it seems to be really popular in Russia.
