Mechanical metamaterials such as origami or ordered 3D printed structures have shown
tremendous applications in science and technology. However, the main disadvantage of …

Graphene oxide (GO) in aqueous solution was aerosolized and rapidly dried to produce
crumpled nanopaper-like sheets. Online size selection and aerosol mass analysis was used …

Aqueous aggregation processes can significantly impact function, effective toxicity,
environmental transport, and ultimate fate of advanced nanoscale materials, including …

Graphene holds promise as an ultracapacitor due to its high specific surface area and
intrinsic capacitance. To exploit both, a maximum surface area must be accessible while the …

A possible solution to solve the restacking issue of graphene oxide (GO) nanosheets during
large-scale production is to turn the two-dimensional (2D) nanosheets into three …

Crumpling a thin sheet of material into a small volume requires energy for creating a network
of deformations such as vertices and ridges,. Scaling properties of a single elastic vertex,, or …

When a thin sheet is crushed into a small three-dimensional volume, it invariably forms a
structure with a low volume fraction but high resistance to further compression. Being a far …

We present a combined experimental and analytical approach to study the formation of
creases in tightly folded Kapton polyimide films. In the experiments, we have developed a …

While simple at first glance, the dense packing of sheets is a complex phenomenon that
depends on material parameters and the packing protocol. We study the effect of plasticity …

We have studied experimentally and theoretically the response of randomly folded
hyperelastic and elastoplastic sheets on the uniaxial compression loading and the statistical …
