Scientists propose anti-fatigue preparation for 3D-printed titanium alloy
2024-02-28 16:58:53
A research team led by Profs. Zhang Zhefeng and Zhang Zhenjun from the Institute of Metal Research of the Chinese Academy of Sciences has proposed an innovative strategy to fabricate an anti-fatigue 3D-printed titanium alloy by separately regulating their microstructure and defects, called as net-additive manufacturing preparation (NAMP).
Prospects for battery recycling in Latin America
2024-02-28 16:58:53
Reuse and recycling are core elements of a sustainable approach to used lithium-ion batteries in Latin America. This is essential to conserve valuable resources and avoid climate-damaging greenhouse gas emissions. The application of tried-and-proven best practices here would potentially avoid the disposal of up to two million tons of batteries as waste and enable up to 2.8 million tons to be recycled in the region by 2050.
