...Chinese student came to our lab

劉洵 Liu Xun
My name is Liu Xun , written as 劉洵(りゅう しゅん). I come from China. I got my master's and bachelor's degrees from the Chinese Academy of Science and Jilin University, respectively. My hobby is cooking, trying various recipes on my way. My current research is on "microfluidic chips with ultra-high velocity and throughput." In addition, FEM simulations of optics, electricity, and mechanism are also in my interests.
We optimized the structure of connections and minimized the microchannel only for minified flow resistance in the microfluidic chip. By our microfluidic chip, a velocity of 40 m/s could be achieved by typical syringe pμmps. Utilizing optical time-stretch (OTS) microscopy, a ultra-high throughput of 2,700,000 cells/s could be reached at 15 m/s.

...We attended the wedding ceremony of Mr. and Mrs. Yamasaki

The wedding and reception of Mr. Yuki Yamasaki, a D1 student of our laboratory, and Mrs. Saki Yamasaki, an administrative assistant, was held in Yokohama.

Faculty members, staffs and alumni attended the ceremony both onsite and online, and Professor Hosokawa gave a congratulatory speech as a guest greeting. In his congratulatory speech, he introduced Mr. Yuki Yamasaki's research theme, and encouraged the couple to support each other's life, using the mechanical state of plant cells, which are supported by the balance between cell walls and internal pressure, as an analogy.

I was happy to hear that the alumni I met for the first time in several months were also doing well in their working lives.

The day was blessed with beautiful weather, and the ceremony was glorious, sunny, and wonderful... Congratulations!
