Chiral liquid crystal elastomers (CLCEs) are soft photonic materials that exhibit both the characteristics of nanoscale periodic helical structures and mechanical properties rubber. Owing to its elasticity, structural color CLCEs can be tuned through deformations known as mechanochromism. Thus far, there is significant research attention exploring mechanochromism CLCEs. However, most studies ha...

We examine, with asymptotic analysis and numerical simulation, the iterated stretching dynamics of FENE and Oldroyd-B jets of initial radius r0 , shear viscosity n, Weissenberg number We, retardation number S, and capillary number Ca. The usual Rayleigh instability stretches the local uniaxial extensional flow region near a minimum in jet radius into a primary filament of radius @Ca(12S)/We#r0 ...

Cells are mechanosensitive to extracellular matrix (ECM) deformation, which can be caused by muscle contraction or changes in hydrostatic pressure. Focal adhesions (FAs) mediate the linkage between the cell and the ECM and initiate mechanically stimulated signaling events. We developed a stretching apparatus in which cells grown on fibronectin-coated elastic substrates can be stretched and imag...

Aligned wavy-structured thermally grown silicon dioxide films are fabricated for stretchable encapsulation films. Uniaxial stretchability is investigated with micromechanics modeling, which can elucidate the arising from wavy structure and properties of materials. The optimum combinations film thickness show 20.1% uniaxial 1.11 × 10−6 g m−2 day−1 water vapor transmission rate (WVTR), simultaneo...

Using a previously developed coarse-grained model, we conducted large-scale (∼ 85 × 85 × 85 nm(3)) molecular dynamics simulations of uniaxial-strain deformation to study the tensile behavior of an epoxy molding compound, epoxy phenol novolacs (EPN) bisphenol A (BPA). Under the uniaxial-strain deformation, the material is found to exhibit cavity nucleation and growth, followed by stretching of t...
