Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Massively parallel aerodynamic shape optimization

Computing Systems in Engineering, 1992
Abstract We consider the problem of finding the shape of an airfoil which produces a pressure distribution closest to a desired one. The flow is modeled by the nonlinear potential equations of compressible flow. The problem is formulated as an optimization problem constrained by a discrete approximation to a nonlinear boundary value problem.

Effect of Shape Parameterization on Aerodynamic Shape Optimization

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
This paper studies the effect of shape parameterization on automatic aerodynamic shape optimization. Four shape parameterization techniques are studied: mesh points, Hicks-Henne bump functions, B-spline curves and the PARSEC method. The objective is to compare them based on accuracy and impact on the computational cost.
