Researchers from the University of Witwatersrand in South Africa have reported a review of research on residual stresses in carbon steel welding: formation mechanisms, mitigation strategies, and advances in advanced post weld heat treatment technologies. The relevant paper titled "A comprehensive review of residual stresses in carbon steel welding: formation mechanisms, mitigation strategies, and ...
Recently, American photonics giant Coherent and Japan's Faraday 1867 Holdings signed a Letter of Intent (LOI), with the goal of expanding the manufacturing scale of high-temperature superconducting (HTS) tapes to be widely used in large-scale deployment of nuclear fusion reactors, while also promoting the transformation of green energy. Coherent's excimer laser is expected to be more widely used i...
Conservation of energy is a fundamental concept in physics that can be used to explain anything from planetary orbits to the internal workings of individual atoms.Energy can be converted into other forms, but the overall energy level is usually considered to vary over time. Therefore, when attempting to describe a system, physicists usually pay attention to ensuring that it is isolated from the su...
The ocean covers over 71% of the Earth's surface, and so far humans have only explored about 5% of the ocean. This means that there are still 95% of the depths of the ocean that we know nothing about, making it the most mysterious and unknown place on our planet.600 years ago, Zheng He led a fleet to play the prelude to the era of great navigation, laying the foundation for us to understand the wo...
