Recently, the first batch of single-point diamond lathes of Tianfu Xinglong Lake Laboratory , the supporting unit of Sichuan Engineering Research Center of Digital Materials, was successfully delivered, and the laboratory's ultra-precision lathe processing capabilities have been initially formed .
Relying on the processing capability of ultra-precision lathes, the laboratory has successfully delivered metal reflectors (cylindrical surfaces), nickel-plated processing mold cores (defocused mirrors) , infrared lenses and other products to Xi'an Institute of Optics and Precision Mechanics, Sichuan University, Chongqing University and other units, and all indicators have met or exceeded customer requirements. Tianfu Xinglong Lake Laboratory is equipped with a single-point diamond lathe , which is suitable for complex and precise optical surface processing, such as aspheric lenses, Fresnel lenses and ultra-precision molds. The maximum processable size of the single-point diamond lathe is 600×250×400mm (X stroke ×Y stroke ×Z stroke ) , the surface accuracy PV ＜0.1um , and the surface roughness Ra ＜2nm .

Rice-derived recombinant human albumin is mainly used to treat ascites caused by liver cirrhosis. Since it's derived from rice, it can be produced in large scale.
China's 5G user penetration rate now exceeds 79%.

Nice, I wonder how much the rice derived albumin costs. It's like $100 for a 100ml bottle here.
The world's brightest and most energy-efficient: HKUST develops a new generation of QRLED to revolutionize smartphones and TV screens..
the Hong Kong University of Science and Technology officially announced on July 15 that it has developed a new generation of QRLED, which will revolutionize smartphones and TVs with ultra-high brightness and colorful displays.
Researchers from the School of Engineering at the Hong Kong University of Science and Technology have overcome a major challenge in display technology by developing the world’s brightest and most energy-efficient quantum rod LED (QRLED) .
This invention achieves high performance in the following areas:
- Record Efficiency: Converts electrical energy into light more efficiently than ever before, achieving an external quantum efficiency (EQE) of 24%, compared to 22% in previous models.
- Brightness per unit of energy: Produces 89 cd A⁻¹ (candela per ampere), a measure of brightness per unit of energy, exceeding all existing QR LEDs .
- Ultra-bright output: 3 times brighter than older green LEDs , reaching a peak brightness of over 500,000 cd m⁻².
- A leap in lifespan: Demonstrated operational stability of over 22,000 hours, making the technology suitable for commercial display applications.
Cambrian adjusts its private placement plan to raise 3.985 billion yuan to increase investment in large-scale model chips and software platforms
Cambricon released an announcement announcing the adjustment of the plan to issue A-shares to specific objects in 2025. According to the latest plan, the company intends to issue no more than 20.9175 million shares and raise no more than 3.985 billion yuan in total. After deducting the issuance costs, the raised funds will be mainly used for chip platform projects for large models, software platform projects for large models and to supplement working capital.
As a global emerging leader in the field of smart chips, Cambricon has rapidly industrialized its technology since its establishment in 2016, forming a full-scenario smart chip product matrix covering the cloud, edge, and terminal. The company has successively launched the Cambricon 1A, 1H, and 1M series of terminal smart processors, as well as a series of cloud-based smart acceleration cards based on the Siyuan 100, 270, 290, and 370 chips, and has entered the edge computing market with the Siyuan 220 chip.
In recent years, Cambrian's intelligent chip products have been rapidly implemented in multiple vertical industries such as operators, finance, and the Internet, and have carried out in-depth adaptation and cooperation with companies in the large model field, which has been highly recognized by industry customers. The company's core technologies such as intelligent processor instruction sets, microarchitectures, programming languages, and mathematical libraries have high barriers and strong ecological value, which are of great significance to the development of artificial intelligence and integrated circuit industries.
