Peking University researchers led by Cui Guang and Liu Zhongfan have developed a flexible aircraft coating just 0.1mm thick that withstands temperatures up to 1,000 degrees Celsius while absorbing radar waves. Published in Advanced Materials, the breakthrough graphene-based metasurface reduces radar reflection to -42 decibels and maintains performance under 200 metres per second airflow with less than 1 percent loss, potentially revolutionizing stealth fighter technology.

Chinese researchers from Peking University have created an analogue computing chip that could process calculations 1,000 times faster than Nvidia's flagship H100 GPU while using a fraction of the power. Professor Sun Zhong's team has solved the century-old precision problem that plagued analogue computing, achieving accuracy comparable to digital systems for AI and 6G communications applications, with the device already surpassing top-tier GPUs in solving medium-scale matrix
