(
Royal Society of Chemistry
, 2017 , Article)
Nickel-cobalt layered double hydroxides (Ni-Co-LDH) have recently been examined for their potential as battery-type hybrid supercapacitors made from metal hydroxide electrode materials, due to their unique spatial structure, ...
Hierarchical honeycomb auxetic metamaterials
(
Nature Publishing Group
, 2015 , Article)
Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson’s ratio. Here we develop a new class of two dimensional (2D) metamaterials with ...
