Deformable micro-supercapacitor fabricated via laser ablation patterning of Graphene/liquid metal

npj Flexible Electronics
Deformable and miniaturized energy storage devices are essential for powering soft electronics. Herein, we fabricate deformable micro supercapacitors (MSCs) based on eutectic gallium-indium liquid metal (EGaIn) current collectors with integrated graphene.

Block Copolymer at Nano-Patterned Surfaces

, 2012
We present numerical calculations of lamellar phases of block copolymers at patterned surfaces. We model symmetric di-block copolymer films forming lamellar phases and the effect of geometrical and chemical surface patterning on the alignment and ...

Block copolymer crystalsomes with an ultrathin shell to extend blood circulation time

Nature Communications, 2018
In block copolymer vesicles, crystallization often leads to defects and renders the structures leaky that undermines their potential biomedical application. Here the authors use an emulsion solution method to control the crystallization of an amphiphilic
