TL;DR: Combining compliant electrode arrays in open-mesh constructs with hydrogels yields a class of soft actuator, capable of complex, programmable changes in shape.
Journal ArticleDOI
Harvesting environment energy from water-evaporation over free-standing graphene oxide sponges
TL;DR: In this paper, a type of porous graphene oxide (GO) sponges is fabricated using the freeze-drying method, and then an annealing treatment and UV+O3 oxidation are carried out to achieve partially reduced GO (rGO), which can convert environmental energy to electricity via the natural evaporation of water.
Journal ArticleDOI
Fatigue and fracture behavior of nickel-based superalloy Inconel 718 up to the very high cycle regime *
TL;DR: The fatigue and fracture behavior of nickel-based superalloy Inconel 718 was investigated up to the very high cycle regime under rotary bending tests at room temperature.
Journal ArticleDOI
Comparison of the very high cycle fatigue behaviors of INCONEL 718 with different loading frequencies
TL;DR: In this article, the authors investigated the differences of very high cycle fatigue (VHCF) behavior of nickel based superalloy IN718 with different loading frequencies, and found that the higher frequency produced an upper shift of the S-N curves.
Journal ArticleDOI
Simulation of the Transient Behavior of Gels Based on an Analogy Between Diffusion and Heat Transfer
TL;DR: In this article, a finite element method is developed in the framework of a commercial finite element package ABAQUS via two material-specific user subroutines to describe the mechanical and mass diffusion behaviors of gels.
