Nanowire meshes to improve electrochemical devices

Nanowerk.com - 18 января, 2019 - 08:53
By re-designing interconnected nanowire networks, researchers fabricated novel nanostructured current collectors, which are the first to combine very high surface area, high porosity, substantially large pores and mechanical flexibility. Thanks to its ordered microstructure, the material can uniquely combine high porosity of cellular metal foams with high surface area of state-of-the-art nanoporous dealloyed metals, which allowed it to surpass the electrochemical performance of up to 300-thicker commercial electrodes.

Graphene researchers are inspired by spider webs

Nanowerk.com - 17 января, 2019 - 09:54
Motivated by the high level of flexibility exhibited by spider webs, scientists have developed a novel design for highly flexible and sensitive piezoresistive sensors based on an elastomer-filled graphene-woven fabric (E-GWF) structure. This technique mimics the distinct core-shell structure of spider webs. This fabrication method could also be extended to other 1D and 2D materials for many emerging practical applications. In addition to excellent sensing capability, the E-GWF also shows unusual switching behavior at large strains owing to the reversible cracking and reconnection of interconnected graphene tubes.
