The UV cross-linking technique applied to the cornea is a popular and effective therapy for eye diseases such as keratoconus and ectatic disorders. The treatment strengthens the cornea by forming new cross-links via photochemical reactions and, in turn, prevents the disease from further developing.
Our article on MD simulations of shock propagation and spallation in polymers has been published in the Journal of Applied Mechanics.

Dear colleagues,
We are happy to share a recent collaborative study on experimental and numerical investigation of rapid synchronized fabrication of vascularized thermosets and composites. This study demonstrated that a thermoset polymer or polymer composites with embedded microvascular systems can be fabricated in a single step, using a self-propagating polymerization reaction front. For more details, please see: https://www.nature.com/articles/s41467-021-23054-7
Mechanical performance of silicon nanopillars with homogeneous and gradient nanotwinned structures are investigated through a series of molecular dynamics simulations. The most observed Σ3 twin boundary (TB) with two preferable (lowest surface energy) planes of {111} and {001} are used to generate homogeneous and gradient nanotwinned structures. Simulations of compression and tension of nanotwinned pillars reveal an extra strengthening behavior due to the addition of Σ3 TBs when compared to the single crystalline nanopillar without any TBs.

The plant cell wall possesses an unusual combination of strength and ability to expand without weakening or breaking (a quality required for plant growth), but the molecular basis for these traits has long been unclear. In a collaborative study led by Prof. Sulin Zhang and Prof.
In this work published in PNAS (https://www.pnas.org/content/118/19/e2100077118), we present compliant 3D frameworks that incorporate microscale strain sensors for high-sensitivity measurements of contractile forces of engineered optogenetic muscle tissue rings, supported by quantitative simulations.
