Towards a curvature theory for general quad meshes
, 2023 We present a curvature theory for general nonplanar quad meshes (a discrete analogue of smooth parametrized surfaces). As in the smooth setting, the resulting curvatures can be understood both in terms of a Steiner-type offset formula (extending the curvature theory for quad meshes with planar quadrilaterals) and in terms of the first and second ...

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Advanced Functional Materials, EarlyView.Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Parallel Constrained Delaunay Meshing
, 1997 We present a parallel unstructured grid generation method based on the Constrained Delaunay Triangulation (CDT). The Parallel Constrained Meshing Algorithm uses certain edges of the initial mesh as constraints that, without compromising the grid quality,

Advanced Healthcare Materials, EarlyView.Diabetic wound healing is hindered by a pathological crosstalk wherein elevated IL‐11 induces M1 macrophage polarization, leading to IL‐1β/IL‐6 release and subsequent fibroblast senescence via RAS/p38MAPK/p53/E2F1 signaling. Here, we develop a Gel@M‐Rho microneedle patch that delivers rhoifolin‐loaded, macrophage membrane‐coated nanoparticles to target
