Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna
Advanced Functional Materials, EarlyView.We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

The Journal of Chemical Thermodynamics, 2003
Abstract The strain energy of phenanthrene was derived to be (4.9 ± 2.8) kJ · mol −1 , on the basis of the latest standard enthalpies of formation of polycyclic aromatic hydrocarbons. This strain energy agrees well with those estimated from a semi-empirical calculation and from the basicity in hydrogen fluoride solution.

Deformational strain energy and erythrocyte shape
Journal of Biomechanics, 1986Analyses of erythrocyte deformation commonly assume the discocytic shape to be unstressed and hence to be without strain energy. This assumption is based on micropipet experiments and a theoretical disparity between observed and requisite curvature rigidity.

The Strain-Energy Function for Elastomers
Transactions of the Society of Rheology, 1976It has been shown that the strain-energy function for an incompressible isotropic elastic material must be expressible as a function of two strain invariants I1, I2 which are elementary symmetric functions of the squares of the principal extension ratios λ1, λ2, λ3. Valanis and Landel have proposed a strain-energy function of the form f(λ1)+f(λ2)+f(λ3).

On the Strain Energy of Shells
Journal of Applied Mechanics, 1954Abstract In a previous paper, the strain energy of a shell was derived with the aid of the assumption that only the linear terms in the thickness co-ordinate z need be retained in the expressions for the strains. Recently, Bleich and DiMaggio derived a strain-energy expression for circular cylindrical shells without using power series in

Elastic strain energy of inhomogeneous solids
Physical Review B, 1995A two-phase elastically inhomogeneous coherent mixture of two phases with the transformation-induced crystal lattice misfit is considered under the loaded and unloaded conditions. It is assumed that the constituent phases particles, composing the mixture, have the structural pattern of an arbitrary morphology but the system is macroscopically ...
