News on China's scientific and technological development.

[broadsword]

That should lay to rest any claim that China was content with relying on foreign technology and putting local development on the back burner. It was hotly debated here.

I just heard someone say that it will take more than a decade for US to establish the rare earth supply chain, what are the people estimating here?

My estimate is 3-5 years, and I can expound on that. For China, it must aim for complete tech self sufficiency in this time horizon.

In Nov 2024, America started to re-establish its TNT production in Muhlenberg County, Kentucky.
If everything goes on well, the facility will be available in Nov 2028, i.e. 4 years.
The investment is $435 million.
To set up RE processing from scratch is likely to be much more difficult.

China’s export controls may end the era of ‘de-risking from China’ with Chinese technology

It’s always jarring to visit European startups who speak about “reducing reliance on China,” while standing in factories filled with machines labeled in Chinese.

China’s controls may force the West to accept investments from Chinese companies in order to build electric vehicle and battery supply chains. These may be the only companies granted licenses to export such machines and technologies. That’s already happening. Recent deals include a

between China’s Shanshan and France’s Imerys to make synthetic graphite materials in Europe.

Any chinese company investing in Europe now is a fool. Its clear they will be seized or forced out once Europe had enough rare earth supply.

A team from Peking University in my country has overcome the century-old problem of analog computing and developed a high-precision analog matrix computing chip! It uses the laws of physics to directly solve matrix equations with ultra-fast speed and extremely low energy consumption. When processing a 128x128 matrix, the throughput is more than 1000 times that of top GPUs!

That should clearly have applications towards AI as well.

It is more than just AI. Radar, sonar, thermal imaging, ... thanks to digitalization, more and more military equipments now use "arrays of sensors". They all produce matrix that must be processed in realtime.

团队将它应用到了“大规模MIMO（多输入多输出）信号检测”中——仅用3次迭代，恢复的图像就和原始图像高度一致，误码率和32位数字计算效果相当，凸显其在实时信号处理中的潜力。

This, and the 2 dimensional flash reported just a few weeks ago, and the 2 dimensional RISC-V CPU from a few months ago, can potentially reshape the landscape of computing in the coming decades.

Looks pretty clear from this recent announcement that China will expand its import of Tungsten and Copper scraps. China has had an import ban on Tungsten scraps for a while, but this was a problematic policy after it imposed export control on Tungsten.

This has been speculated for a few month now

so given that China produces 82.7% of Tungsten globally and is now also buying up scraps, will make it hard for others.

My update on the current status of Tungsten

It feels like China is going to be more aggressive in going after metal scraps and recycling in the international market.
