Biomimetic folding of triangular deployable membranes (2022)
Journal Article
Tang, Y., Beccarelli, P., Guo, H., Liu, R., De Focatiis, D., & Deng, Z. (2022). Biomimetic folding of triangular deployable membranes. Bioinspiration and Biomimetics, 17(6), Article 066002. https://doi.org/10.1088/1748-3190/ac7fd3

Deployable membranes are being increasingly applied in numerous space projects owing to their light weight, small stowage volume and capacity for use at large scales. The geometric design of biomimetic folding is studied to design crease patterns for... Read More about Biomimetic folding of triangular deployable membranes.

A self-crosslinking monomer, α-pinene methacrylate: understanding and exploiting hydrogen abstraction (2022)
Journal Article
