1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
Expanding our scientific understanding often boils down to observing what is happening as closely as possible. Now, researchers from Japan have observed the nanoscale behavior of azo polymer films and triggered them with lasers.In a study published in Nano Express last month, researchers at Osaka University used a combination of cutting-edge scanning high-speed atomic force microscopy and optical ...
