The article discusses the critical role of microchips and semiconductors in modern technology and their impact on global politics and economy. It highlights the importance of silicon in technological advancements and how the production and distribution of microchips are globalized, involving countries like China, the US, Taiwan, the Netherlands, and South Korea. The piece touches on the historical development of chip technology, with a focus on Taiwan's significant role in manufacturing and the US's consumption and production for military uses. It also addresses the geopolitical tensions between the US and China, with the US banning chip exports to China and both countries striving to develop their own chip technologies. The article concludes by reflecting on the broader implications of this competition for global order and the need for international cooperation to address challenges like climate change.

The article presents a study on the characteristics and performance of spacer rings in bearings. A new testing method was proposed to evaluate the basic characteristics, surface properties, and serviceability of spacer rings. The study found that the composition of spacer rings, which mainly includes elements like Fe, Al, P, Si, Ca, and S, contributes to their wear resistance, hardness, strength, and corrosion resistance. The porous nature of the spacer rings enhances lubricity, and the surface roughness is generally less than 0.6 μm Sa, indicating a relatively flat surface. The average friction coefficient was found to be 0.85, suggesting good friction and wear properties. The research aims to establish testing and evaluation criteria for spacer rings, which is crucial for improving the performance of bearings in various industries. The study was funded by the Basic Scientific Research Project of Liaoning Provincial Education Department and involved authors from Dalian Guangyang Bearing Company Limited.
