He Haijun, PhD student of BME Faculty of Mechanical Engineering, Department of Polymer Engineering, gained the first prize of the BMe research Grant. Mostly PhD students aspire for the grant, created to support professionally outstanding researchers.
How did you feel when you got to
know that you were given the honour?
It
is hard to describe. Firstly, I was surprised with the first prize of the BMe Research
Grant because I did not expect to achieve that much. Then I felt highly
satisfied and fulfilled. I have been very eager to get this award since the first
year of my PhD study in 2017. Now I am having the fourth year of my BME
studies. When I received an email from the doctoral school about the
application information of the grant in 2017, I thought it was probably only
for domestic students. But one year later I received the similar email about its
application information. I
started realizing that it might be available for me as well. I asked my
supervisor Dr. Kolos Molnár and my colleagues, they told me that this grant is
for the best PhD students including foreign PhD students. But at that moment, I
did not have strong confidence because of my achievements, like articles. Therefore,
I promised myself to apply later. Until this year, I thought, this is my last
chance to apply.
Can you tell us some details of
your research topic?
My PhD topic is about nanofibers, the fibres with
diameter around nanometers.
The
technology of electrospinning is the leading technology to produce nanofibers.
I aimed to create a new method for electrospinning, to produce nanofibers with
high quality and finer diameter. There are technical issues in this technology
because we cannot achieve significant productivity in industry, so currently it
is just lab research and hasn't gone to the industrial application. In my
research, I propose to invent an electrospinning method and improve
productivity.
At
the second part, I try to investigate the micro-structure of nanofibers from
the materials science direction, not from the engineering direction. And the
last part is that I have to find a place where nanofibers can be used and applied.
At the outbreak of the COVID-19, I also started to research how nanofibers can be used as a mask filter, because the nanofiber has a partial advantage as a filter, compared to a standard filter used in our mask. I also proposed a smart mask for detecting the respiration parameters of people in real time, like what is your inhalation and exhalation time, or breathing frequency. Because respiration state is one of the most important vital sign of humans to show the illness. It is the most exciting and useful part of this research. I also started to apply for a patent, and it is in process.
You graduated at Xi'an
Polytechnic University in China. Why did you choose BME?
At
Xi'an Polytechnic University, I studied in textile engineering. After finishing
MSc, I was thinking about doing my PhD studies at a European university, but I had
no idea where to go. I was delighted when I found this opportunity at BME with
Stipendium Hungaricum programme. Even I found that the Department of Polymer
Engineering was initiated from the Department of Textile Technology more than 70
years ago – the field, which I graduated from. So I applied immediately without
any doubt.
What did you get from BME?
A lot of knowledge, and many friends.
Hungarians
are helpful. When I arrived, I did not have proper accommodation, so my supervisor
Dr. Kolos Molnár offered me to reside in his apartment for 2 weeks and helped
me settle down in this country I have never been to. He even helped me with
finding and renting an apartment.
Unfortunately,
I got used to changing my apartment every year due to some issues. And my stuff
was getting more and more, it was not possible to move them with the public
transportation. My friends at department always helped me carry my things with
their cars even though they were busy. I really appreciate them.
Lastly,
I have to add that although people always says that PhD studies are the most
challenging part of life. But the PhD study at BME makes me not feel that
tough, instead, it gives me the calmness and the balance between work and life when
doing my research. It teaches me how to make an enjoyable PhD life. And I also have
time to do my hobbies, I am a marathon runner.
How do you feel here in Budapest?
It is a very comfortable city to live and do research.
Budapest is lovely.
What are your plans?
I
would like to submit my PhD dissertation in next month. After my PhD, I would
like to do a post-doc, but I am not sure where. After my post-doc, I would like
to return to China, and my final goal is to become a professor at a university.
I would like to pass what I have learnt and give inspirations to my future students.
Doing research is an enjoyable job for me.
