Assembly and integration of two-dimensional nanomaterials for advanced interfaces and sensors
… buckle-delamination induced microscale crumples using a shape-memory polymer. Moreover, I achieve bio-inspired hierarchical structures of graphene by combined use of 3D microstructure substrates and mechanically-driven nanoscale crumples of graphene, which exhibit a potential for a …

Formation of three-dimensional graphene structures by controlled thermal activation of polymeric shape memory substrates
… deterministically pattern graphene and graphite crumples in a spatially selective manner from otherwise flat graphene/graphite is achieved via infrared activation, which has not been previously possible with other methods such as relaxation of mechanically pre-strained elastomers, contraction of …

Buckling Patterns and Mechanics of Thin Interfacial Polymer Films
… indentation setting to a broad study of crumples in varied geometries and boundary conditions. We construct an empirical phase diagram of the wrinkle-to-crumple transition which suggests crumples are a generic micro-structure that emerges at large curvatures due to a competition of …

Strechable crumpled graphene photodetector with plasmonically-enhanced photoresponsivity
… fabrication of different degrees of hierarchical crumples of graphene on microstructure array, which can be exploited to control surface wettability. Here, we achieved to create hierarchical structures of graphene in microscale by using three-dimensional (3D) features on a substrate and in …

Mechanical self-assembly of deformed 2D materials for advanced functionalities
… buckle-delaminated structure with delocalized crumples and inhomogeneous strain in the crumpled 2D lattice. Furthermore, we create mixed-dimensional structures by combining our architecturing strategy with unconventional crack lithography. Through the crack lithography – inspired strategy, …

Registration and categorization of camera captured documents
… and non-rigid deformations e.g., folds and crumples. Document registration is a problem where the image of a template document whose layout is known is registered with a test document image. Literature in camera captured document mosaicing addressed the registration of captured documents …
