I think @FairAndUnbiased once mentioned that semicon equipment developments can spur another industries.
Could be useful at tour sites if people want up and close view of certain areas. Obviously they shouldn’t have control over these but still, will be interesting immersive experience.
Yet another advanced research scientific infrastructure from China ..
on January 10 the Institute of Physics, Chinese Academy of Sciences announced the construction of the Advanced Attosecond Laser Facility, a major national scientific and technological infrastructure in Dongguan, Guangdong, officially started today ..
1 attosecond = 10 -18 seconds, which is the fastest time scale that humans can currently master. With the help of attosecond lasers, it is possible to detect the movement of electrons inside molecules that is difficult to observe with femtosecond (10 -15 seconds) lasers. Scientists can track, measure, and manipulate the movement of electrons, just like using an "ultra-high-speed camera" to capture the "dynamic image" of electrons.
Public information shows that the facility is being built by the Chinese Academy of Sciences, with a total of 10 beam lines and 22 application terminals, and a construction period of 5 years.
The six beamlines that have started construction are managed by the Institute of Physics of the Chinese Academy of Sciences, and the other four beamlines will be built in Xi'an, Shaanxi, and will be managed by the Xi'an Institute of Optics and Precision Mechanics of the Chinese Academy of Sciences. After the facilities are completed, they will provide strong support for multidisciplinary frontier basic research and industrial applications in physics, chemistry, materials, information, biomedicine, etc.

objectives -
- Achieve full wavelength coverage from nano-soft X-rays to millimeter-terahertz
- Realize the tracking, measurement and control of electronic movement
- Conduct optical-electrical-magnetic-thermal integrated experiments with ultra-high time resolution, spatial resolution, and energy resolution
Yeah that makes sense semi conductor is pretty much at the edge of human engineering and science. Going somewhere else is using the path already taken and adjust it to another industry.

Aluminum Surface Work Hardening Enables Multi-Scale 3D Lithography
The AL-3DLitho technique utilizes aluminum's work-hardening properties to generate remarkably precise, multiscale patterns. By employing a sequential nano-micro-macro imprinting process, the researchers achieved highly accurate patterns across multiple length scales. Furthermore, this process allows for fine-tuning through anodization, facilitating the creation of customizable nanoholes and high aspect ratios. Such features make AL-3DLitho an ideal framework for developing sophisticated materials.
A standout feature of AL-3DLitho is its strong compatibility with a range of deposition techniques, enabling efficient production of both homogeneous and heterogeneous structures. This versatility allows AL-3DLitho to work across numerous material types—such as carbon, semiconductors, metals, and polymers—while achieving precision at length scales spanning from nanometers to centimeters, or even larger.
To showcase AL-3DLitho’s potential, the Westlake research team demonstrated its capabilities by fabricating advanced “on-chip” pressure and biosensors. These sensors, developed using two integrated multiscale carbon networks, can be custom-designed for specific performance requirements. Key applications of these sensors include real-time monitoring of health metrics, such as pulse rate and uric acid levels, offering valuable data on how these indicators vary in response to dietary habits over time. This breakthrough holds great promise for personalized health monitoring and fitness tracking.
The world's first carbon fiber subway train officially starts commercial operation
the world's first carbon fiber subway train "CETROVO 1.0 Carbon Star Express" jointly developed by CRRC Sifang Co., Ltd., a subsidiary of CRRC Corporation Limited, and Qingdao Metro Group was officially launched on Qingdao Metro Line 1 and put into commercial operation. The train fills the international gap in the commercial use of carbon fiber composites in the main load-bearing structure of subway vehicles, leading China's subway trains to achieve a new upgrade in lightweight and green. The main load-bearing structures of the "Carbon Star Express Rail", such as the car body and bogie frame, are all made of carbon fiber composite materials, which is the first time in the world that carbon fiber composite materials have been used in the main load-bearing structure of subway vehicles for commercial passenger transportation. Compared with traditional subways, this carbon fiber subway train has been completely upgraded, with significant advantages such as lighter and more energy-efficient, more comfortable to ride, higher strength, less wheel-rail wear, and lower operation and maintenance costs.
Lighter and more energy-efficient
By using carbon fiber composite materials, the vehicle has achieved a significant "weight loss". Compared with traditional metal vehicles, the vehicle body is 25% lighter, the bogie frame is 50% lighter, and the vehicle weight is about 11% lighter. The lighter body makes it more energy-efficient to run, and the operating energy consumption is reduced by 7%. Each train can reduce carbon dioxide emissions by about 130 tons per year, which is equivalent to planting 101 acres of trees.
More comfortable ride
Thanks to the use of carbon fiber composite materials, the vehicle has better vibration reduction and isolation effects, and runs more smoothly. The active radial bogie technology is used for the first time in the field of commercial subway trains, which can actively control the wheels to pass through curves along the radial direction, greatly reducing the "howling" when passing through curves, reducing the curve passing noise by 15 decibels, and reducing the noise inside the car by 2 decibels, making the operation quieter.
Higher strength
Compared with metal body, the carbon fiber train has stronger body strength and higher safety factor. At the same time, the bogie frame made of carbon fiber composite material has stronger impact resistance, better fatigue resistance and longer structural life.
Less wheel and rail wear
The lighter carbon fiber body reduces the vehicle axle weight and reduces the wheel-rail force by more than 15%, thereby reducing wheel-rail wear. The use of active radial bogies also reduces wear on wheels and tracks.
Lower operation and maintenance costs
The wheel-rail wear is less, and the maintenance of vehicle wheels and tracks is greatly reduced. At the same time, the vehicle uses digital twin technology to build the SmartCare intelligent operation and maintenance platform for carbon fiber trains, which realizes intelligent detection of vehicle faults, intelligent assessment of health status, and optimization of repair procedures and systems, reducing maintenance costs. By adopting new materials and new technologies, the maintenance cost of the vehicle throughout its life cycle is reduced by 22%.
