章 481: Chapter 299: Mechanical Peeling Preparation Machine Technology (Requesting Subscription)_2

Why did Ding Yue sense a tone of disappointment in his sister's voice?

"Little sister, you sound rather exhausted. Are the experiments not going well?" Ding Yue curiously inquired.

"More than 'not going well', the gas deposition method I mentioned last time is pretty much a dead end." Ding Xiaoyou said helplessly.

"Er, didn't you tell me last time that the optimized gas deposition method was about to be realized?" When Ding Yue heard this, he instantly furrowed his brow.

If Ding Yue remembered correctly, the last time he spoke with his sister, she mentioned that the method she was researching on the chemical production of graphene, namely the gas deposition method, was on the brink of successful optimization.

So why has she suddenly declared her failure? Even going so far as to say it was a dead end?

As someone experienced in research, Ding Yue knew all too well what it meant when someone said that "the road was blocked". It simply meant that the path was unviable.
