Caption

Polyethylene (PE) is susceptible to crack initiation and propagation when exposed to stress. In a new study, researchers from Shibaura Institute of Technology, Japan, have employed focused electron beams to precisely induce micro-voids and nano-scale fibrils to improve the mechanical strength and prevent crack propagation in PE.
