News on China's scientific and technological development.

China's new generation meteorological supercomputing system is completed: the computing power is increased by 6.5 times, and a national system is introduced for the first time..​

on January 10 that according to official news from the National Meteorological Science Data Center, on December 27, 2023, my country’s new generation meteorological supercomputing system was officially completed, bringing 52PFlops (5.2 trillion floating-point operations per second). With the newly added computing power, the total computing power of the meteorological supercomputer has reached 60PFlops, which is 6.5 times higher than before completion .

The new generation of meteorological supercomputing aims at the new demand for computing power in the high-quality development of meteorology and responds to the national strategy of “computing in the east and computing in the west”, and has built a new layout of five subsystems in Beijing, Horinger, Inner Mongolia, and Xi’an, Shaanxi .

Among them, the national-level (Beijing) supercomputing power reaches 27.48PFlops, and the national-level (Helinger) supercomputing power reaches 20.9PFlops, which together form the "main force" of the new generation of meteorological supercomputing.



According to reports, the construction of the system also takes into account the rapid development trend of artificial intelligence technology, and a new 3.6PFlops intelligent computing power is built at the national level (Beijing) to support the research and development of artificial intelligence meteorological applications and promote independent and controllable large weather forecast models. New breakthroughs were made in key core technologies.

Xi'an Disaster Recovery and Backup Center innovatively adopts the "2+2" architecture and builds two sets of supercomputer systems with a computing power of 2PFlops based on the domestic X86 and domestic ARM architectures. This is the first time that the meteorological department has introduced a nationally produced system . While undertaking the disaster recovery function of weather numerical forecasting business, it is committed to building a domestic “core” ecosystem and laying out the domestically produced meteorological supercomputing system from the inside out.

from the announcement that the China Meteorological Administration was one of the first departments in China to introduce and apply supercomputing systems. In the past four decades, meteorological supercomputing systems have been continuously updated iteratively to support the rapid development of numerical forecast models. The construction of a new generation of meteorological supercomputing systems marks the entry of meteorological supercomputing into a new stage of development, and will fully assist the high-quality development of numerical forecasting and artificial intelligence meteorological applications...

Oh wow a brief case sized power bank could power smartphones for 50 years! Hopefully becomes commercially available soon

Smartphones are not the intended applications for these kind of power cells. These would typically be used for very low power sensors in very remote and isolated areas or in use cases where replacing a battery is very difficult(pacemakers, wildlife trackers)

Helium, which is in short-supply worldwide, is crucial for both practical uses such as in MRI scanners and for scientific research. "Supersolid" opens the door for achieving the coldest temperatures possible without using helium.

Chinese researchers discover 'supersolid' with extreme cooling potentials
Across the globe, scientists and industries face a helium shortage. This inert gas is crucial for achieving extremely low temperatures needed for advanced research and technologies like superconducting magnets and MRI machines. But with limited reserves and rising extraction costs, finding alternatives is crucial.

This is where the newly discovered supersolid material comes in. It's made of cobalt and can be cooled to near absolute zero (almost minus 273 degrees Celsius), the coldest possible temperature, without needing helium.

Ultrastrong and High Thermal Insulating Porous High-Entropy Ceramics up to 2000 °C​

Abstract​

High mechanical load-carrying capability and thermal insulating performance are crucial to thermal-insulation materials under extreme conditions. However, these features are often difficult to achieve simultaneously in conventional porous ceramics. Here, for the first time, it is reported a multiscale structure design and fast fabrication of 9-cation porous high-entropy diboride ceramics via an ultrafast high-temperature synthesis technique that can lead to exceptional mechanical load-bearing capability and high thermal insulation performance. With the construction of multiscale structures involving ultrafine pores at the microscale, high-quality interfaces between building blocks at the nanoscale, and severe lattice distortion at the atomic scale, the materials with an ≈50% porosity exhibit an ultrahigh compressive strength of up to ≈337 MPa at room temperature and a thermal conductivity as low as ≈0.76 W m−1 K−1. More importantly, they demonstrate exceptional thermal stability, with merely ≈2.4% volume shrinkage after 2000 °C annealing. They also show an ultrahigh compressive strength of ≈690 MPa up to 2000 °C, displaying a ductile compressive behavior. The excellent mechanical and thermal insulating properties offer an attractive material for reliable thermal insulation under extreme conditions.

The fifth Chinese Antarctic research station at Inexpressible Island is under construction. Video is a summary of the progress.

Progress on CEPC (Circular Electron-Positron Collider)

Can anyone confirm ?

CEPC is going according to the project development plan. Currently the project is at final phases of technical design according to Li Yuhui, the deputy director of IHEP CAS, who spoke about the project at a physics conference at Nanjing University few months ago. Concurrently, feasibility studies are being conducted at seven preliminary sites. Final location will be one of these places - Changchun, Qinhuangdao, Xiong'an, Xianyang, Changsha, Huzhou or Guangdong.

Allegedly from Thailand.

China's first and World's second 8.6-generation AMOLED display Technology ..

on January 10 that according to "Chengdu Daily", Chengdu High-tech Zone and BOE Technology Group Co., Ltd. signed an investment cooperation agreement in Chengdu to build the country's first and the world's second 8.6-generation AMOLED display device in Chengdu. production line, with a total investment of 63 billion yuan . After the project is completed, Chengdu will become the largest flexible panel production base in the country .

BOE's 8.6th-generation AMOLED production line project is Sichuan Province's largest single industrial project with the largest investment volume to date, and is expected to achieve mass production in the fourth quarter of 2026 .

The product is mainly positioned at medium-sized AMOLED panels, adopting a technical route that is different from the existing 6th generation AMOLED panels, and is mainly used in IT products such as mid-to-high-end notebook computers and tablet computers .

It is worth mentioning that as early as September 2007, BOE’s 4.5-generation LCD panel production line project was launched in Chengdu High-tech Zone . This project was BOE’s first production line outside Beijing and the first LCD panel production line in western China to achieve mass production. At that time, it was the only fully automatic production line in mainland China that realized the integrated production of color filters and LCD panels.

AMOLED is known as the next generation display technology. Compared with traditional LCD displays, it has wider viewing angles, higher refresh rates and thinner sizes. It is widely used in mobile phones, monitors, TVs and other display devices.

The display generation line generation is defined according to the size of the glass substrate used in the production of display screens. The size of the glass substrate of the 8.6 generation line is 2250*2600mm..
