When AI Enters the Laboratory: A Scientific Revolution from Blind Trial and Error to Precise Success
Hello everyone, I'm your financial journalist and economist. Today's news may seem to be about how Professor Wang Haozhe, a materials scientist, uses AI in his experiments, but on a deeper level, it reveals a significant economic and technological transformation: the underlying logic of scientific research productivity is being rewritten.
In the past, conducting research was like opening a blind box, relying on luck and experience to make gradual attempts. Now, AI is acting as a navigator, directly showing us the most effective path. This not only saves months of time but could also completely change the competitive landscape of the future chip and materials industries.
Let me break down this news into five key points to help you understand this revolution in human-computer collaboration:

1. Saying Goodbye to Luck: How AI Turns Research from a Slow Process to a Precise Solution?
The Core Problem:
In traditional laboratories, students often say, “Professor, we need to try this parameter for a few more months.” Why is it so slow? Because research is often like searching for a switch in the dark. Changing the temperature might fail; changing the gas ratio might also fail. Researchers are not clueless about the direction, but they don’t know which specific parameter to test next. This trial-and-error method is extremely time-consuming, costly, and exhausting.
The Change AI Brings:
Professor Wang Haozhe’s team does the following: they let AI do the “homework” first before going into the laboratory. Previously, scientists had to read dozens of papers, copy others’ conditions, and then adjust them according to their lab’s equipment. Now, AI directly analyzes the literature and, considering the lab’s available resources (such as the maximum temperature of the furnace and the setup of the gas lines), provides a set of “executable” parameter combinations. As a result, the sample is successfully produced on the first try. What used to take months of trial and error is now a precise process guided by AI.
A Simple Metaphor:
It’s like being a chef. Before, you had to buy all the ingredients yourself, try different combinations, and maybe succeed after half a month. Now, AI, like a master chef, looks at all the recipes, knows what you have in your fridge, and tells you, “Add 3 grams of salt, 2 grams of sugar, turn the heat up, and cook for 3 minutes.” You follow the instructions, and it works on the first try.

2. From Watching the Action to Understanding the Mechanics: Why Does Wang Haozhe Dare to Trust AI with His Laboratory?
The Background:
During his doctoral studies, Dr. Wang Haozhe focused on “two-dimensional semiconductors,” a type of ultra-thin material crucial for future chips. He realized that the hardest part of science is not just creating something once but doing it consistently 100 times. Later, he转向ed atomic layer etching, which involves cutting materials into extremely thin layers. He predicted that the bottleneck in semiconductor manufacturing would not lie in how to deposit materials but in how to remove unwanted parts.
The Key Insight:
Wang Haozhe dared to use AI because he saw two levels of change it could bring:
1. Efficiency: AI can quickly analyze large amounts of data (such as spectral data), saving time—something he noticed even at MIT.
2. Paradigm Shift: AI can not only calculate but also make decisions. It understands the gap between the ideal conditions described in the literature and the practical limitations of the laboratory.
Why the Confidence?
He realized that AI is not here to take jobs but to bridge the gap between experience and knowledge. Many experts’ insights are implicit (e.g., “This furnace needs a longer preheating time”), and these are hard to codify. However, AI can simulate such expertise by reading a lot of literature and combining real-time data. Wang Haozhe said it clearly: AI isn’t mysterious; it uses simple methods (repeatedly reading literature, testing parameters, sorting) to eliminate unreasonable options and prioritize the most promising ones.

3. More Than Just Talking the Talk: How Does AI Really Control Microscopes and Chemical Reactions?
A Common Misunderstanding:
When people talk about “AI scientists,” they often focus on AI’s ability to write papers or propose hypotheses—abilities that are purely theoretical. It’s like AI can draw perfect blueprints, but it can’t build the actual structure.
Wang Haozhe’s Team’s Breakthrough:
They took it a step further: they let AI directly control the hardware.
- Controlling Microscopes: AI automatically finds the sample, adjusts the view, takes photos, analyzes the results, and selects high-quality crystals—without human intervention.
- Generating Experimental Recipes: When making MXene (a new material), the traditional method used highly toxic and flammable titanium tetrachloride, which was dangerous. AI suggested using hexachloroethane, which is safer and generated over 200 experimental recipes.
- End-to-End Collaboration: AI handles the entire process from idea generation to parameter selection, experiment execution, to data verification, forming a seamless chain.
What Experts Think:
Professor Zhang Jiaheng from the National University of Singapore noted that this represents a significant shift in AI in research: from just coming up with ideas to actually conducting experiments. Professor Kang Wenbin pointed out that traditional methods rely on a lot of trials (maybe 1 success out of 100), while AI can derive results based on internalized knowledge (maybe 25 trials). The efficiency difference is huge.
A Practical Metaphor:
Previously, AI was like a strategist who could only draw a map and say, “Attack east.” Now, it’s like a commando who not only draws the map but also operates the equipment, adjusts the route in real-time, and even avoids obstacles.

4. A Cool Look at the “Miracles”: AI Is Not Magic; Prudence in Science Remains Important
The Calm Behind the Highlights:
The news mentions that when the team first saw the characteristic peak of the target material, they didn’t celebrate. Why? Because one peak doesn’t mean success; there are still steps like structure confirmation, stability testing, and repeated experiments. This shows the rigor of scientists. Although AI is powerful, its results must be verified in the real world.
Three Key Challenges:
Professor Zhang Jiaheng highlights three key areas for verification:
1. Repeatability: Can AI’s success be replicated? Can it be done consistently 100 times? This is the key to moving from a demonstration to practical application.
2. Generalizability: Is the AI model only useful in this lab and with this equipment? Will it work in other companies or with different furnaces?
3. Scalability: How can it be made accessible to ordinary laboratories? If only top-tier labs can afford it, it’s just a toy, not a fundamental tool.
An Economic Perspective:
From an economic standpoint, “repeatability” means standardization. Only with standardization can mass production be achieved, costs can be reduced, and a industry can be formed. AI solves the problem of efficiency from “0 to 1,” but the industrialization from “1 to 100” still requires human engineers to address issues like yield and reliability.

5. The Future Scientist: Not a “Memory Master,” but a “Cross-Industry Commander”
Will AI Replace Scientists?
Wang Haozhe’s answer is clear: No.
He says, “Humans are still the most important part of the research process.” AI doesn’t replace anyone; it changes who asks the better questions.
The Core Competencies of the Future:
Scientists no longer need to memorize a vast amount of literature, formulas, and experimental techniques. AI can handle that for them. Instead, they need to:
- Ask the Right Questions: Identify what is worth studying and which directions are promising.
- Develop Cross-Industry Skills: Wang Haozhe now recruits students from various backgrounds (computer science, physics, chemistry, electronics), because future research will combine materials, algorithms, and engineering.
- Make Judgments: When AI provides 200 options, scientists need to determine which are physically feasible and which are technically practical.
Industry Impact Prediction:
Professor Kang Wenbin predicts that fields where experiments can be easily automated and robotized will be the first to be transformed. This means that chip manufacturing and new material development will no longer rely on traditional, hands-on methods but will be data-driven, with human-AI collaboration.
Implications for Everyone:
If you’re in education or the workplace, don’t worry about AI taking your job. Instead, learn to collaborate with AI, use it to process data and literature, and focus on creative thinking, interdisciplinary integration, and complex decision-making. These will be the most valuable skills in the future.

In Summary
The core message of this news is that AI is evolving from a research assistant to a partner, even participating in experimental decision-making:
- For Researchers: Efficiency is significantly improved, and the cost of trial and error is greatly reduced.
- For the Industry: The development cycle for new materials and chips may be shortened, accelerating technology adoption.
- For Society: The research paradigm is shifting from experience-driven to data and model-driven.
However, this is not a revolution where AI replaces humans but one where humans and AI evolve together. The winners of the future will not be those who reject AI or blindly adore it but those who know how to guide AI and make the final scientific judgments.
This transformation is about creating a new ecosystem where humans and AI work together.
