Liu C, Campbell S, Li J, Bannerman D, Pascual-Gil S, Kieda J, et al.
Adv Healthc Mater . 2022 Sep; 11(23):e2201346. PMID: 36165232
Bioelastomers are extensively used in biomedical applications due to their desirable mechanical strength, tunable properties, and chemical versatility; however, three-dimensional (3D) printing bioelastomers into microscale structures has proven elusive. Herein,...

Li J, Ertorer E, Herman P
Opt Express . 2019 Sep; 27(18):25078-25090. PMID: 31510387
A systematic study of glass scribing is presented on the benefits of ultrafast laser burst trains in generating filamentation tracks to guide cleaving of glass substrates. The interplay of Kerr...
