Journal ArticleDOI
A Self-Healable, Highly Stretchable, and Solution Processable Conductive Polymer Composite for Ultrasensitive Strain and Pressure Sensing
Journal ArticleDOI
Multilayer Polypyrrole Nanosheets with Self-Organized Surface Structures for Flexible and Efficient Solar-Thermal Energy Conversion.
TL;DR: It is demonstrated that multilayer PPy nanosheets with spontaneously formed surface structures such as wrinkles and ridges via sequential polymerization on paper substrates can dramatically enhance broadband and wide-angle light absorption across the full solar spectrum, leading to an impressive solar-thermal conversion efficiency of 95.33%.
Journal ArticleDOI
Lattice Mismatch Dominant Yet Mechanically Tunable Thermal Conductivity in Bilayer Heterostructures.
TL;DR: It is shown that the phonon thermal transport in the graphene-MoS2 bilayer heterostructure is reduced by the lattice mismatch, and the reduction can be mitigated well by an external tension, weakening the effect of inherent mismatch-induced strain on thermal conductivity.
Journal ArticleDOI
Actuating Water Droplets on Graphene via Surface Wettability Gradients.
Qingchang Liu,Baoxing Xu +1 more
TL;DR: A conceptual design of the driving water droplet on a graphene surface is proposed and it is demonstrated that both speed and direction of the movement can be controlled via a continuous gradient of surface wettability using comprehensive molecular dynamics simulations.
Journal ArticleDOI
Theoretical search for heterogeneously architected 2D structures.
TL;DR: Two theoretical frameworks in mechanics are presented to predict the elastic properties of 2D structures and demonstrate their application in a search for novel architected2D structures that are composed of heterogeneously arranged, arbitrarily shaped lattice cell structures with regulatory adjacent bonding connections of cells.
