Chapter 610

Plane to Xia Nation Capital Airport.

First class, the young man and the old man had stacks of A4 paper placed in front of them.

The young man lowered his voice to speak: "Professor Ma, look, here, could we selectively introduce S vacancies at the MoS edge to expose more Mo atoms, improve surface electron mobility, and at the same time promote the dissociation and adsorption of H2O molecules?"

The old man stared at the manuscript for a while, laughed, and seemed a bit emotional: "A good method. Those team members under me studied it for half a month and had no ideas; I didn't expect Professor Xu to find the problem in a few minutes."

"I just happened to stumble upon it."

The young man said modestly.

The flight attendant looked toward their direction from time to time, especially when looking at the young man, her eyes flowing with emotion, looking forward with great anticipation.

A world-class mathematician, Kyoto University mathematics professor... talented, and most importantly, handsome too.

Dressed casually, white sweater plus black trousers, a kind of fascinating, lazy aura revealed in the casual attire.

The line between sloppy and lazy is just that subtle.

After a while, a flight attendant walked over.

"Good evening, two gentlemen. I am your flight attendant Xiaoling, very happy to serve you. This is tonight's menu and wine list; the chef has prepared pan-fried Wagyu ribeye with black truffle sauce, French seafood bisque, and seasonal limited desserts for you. Do you need me to introduce them to you in detail?"

Xu Qingzhou said directly: "No need, thank you. Just serve them to us directly."

"Right, no need to be so troublesome."

Ma Xuan shook his head with a chuckle.

The flight attendant was very professional; in a while, she brought the food and thoughtfully helped the two of them pour the white wine.

During the meal, the topic of the two transitioned from academics to relaxed topics.

Ma Xuan asked curiously: "Does Professor Xu have any plans to take on students?"

"Not for the time being. You know, there are quite a lot of things on hand, and there is simply no time to take on students."

Xu Qingzhou took a sip of wine; taking on students or something, he might consider it in a few years, but he couldn't pull himself away at all right now.

"That's true, just the few projects you have on hand are enough to give you a headache... but then again, you young people all have energy..."

The two finished eating simply and then got busy with their own things.

Xu Qingzhou continued to do calculations on non-metal doping; the trip back to the country was much more interesting than when he came.

The old and the young each held materials in front of them, discussing how to improve the catalytic performance of two-dimensional materials through surface functionalization, such as doping transition metal atoms, for hydrogen evolution reaction (HER) and CO2 reduction.

They also studied the project Professor Ma Xuan's team is currently doing, whether interface defect engineering can be used to increase the density of MoS edge active sites.

12:00 PM Kyoto time, under the flight attendant's reluctant gaze, Xu Qingzhou and Professor Ma Xuan got off the plane.

Capital International Airport.

A girl wearing a trench coat stood gracefully, her gaze falling on the exit.

The girl was about twenty years old, with exquisite features and a high, straight nose bridge, but there was no expression on her face; there was a kind of pure, cold, and indifferent aura in her calm eyes that made many people who wanted to go over to ask for contact information give up the idea.

Until a few minutes later, the girl's expression finally had a reaction, the corners of her mouth lifted, and her smile was sweet, just like a plum blossom suddenly blooming in the cold winter.

Looking over again following the girl's gaze.

It was a young man wearing a black jacket; he looked okay, but his hairstyle was slightly messy, and one could tell at a glance that he had just finished a long-haul flight.

Subsequently, the girl's cold aura dissipated, and she threw herself into the young man's arms.

"Professor Xu~"

The beauty was in his arms, and a fragrance crept into his nose.

Xu Qingzhou hugged the soft body, feeling extremely emotional in his heart; he hadn't seen her for a week, and he really missed this girl a bit.

"Cough~"

The two hugged until a light cough of reminder sounded beside them.

Song Yao climbed out of Xu Qingzhou's arms, her fair cheeks flushed red; just meeting, she was busy cuddling with Xu Qingzhou and almost ignored Professor Ma Xuan beside Xu Qingzhou.

"Professor Ma, this is my partner, Song Yao." Xu Qingzhou introduced her to Professor Ma Xuan.

"I know, I know, Professor Li's brilliant student, right? President Song, hello."
