ABSTRACTIn addition to the piezoelectric nanogenerators and triboelectric nanogenerators, recently, the graphene-based nanogenerator has been widely concerned because of its simple assembly, flexibility and high structural stability. There are many interesting effects in graphene applied for nanogenenrators including anion adsorption in electrolyte solution, ion channels in graphene sheets network and the strain (band engineering) effect, etc. In this paper, we focus explicitly on the experimental results, mechanisms and applications of the graphene-based nanogenerator, and introduce our recent research on the graphene-based nanogenerator based on "modulation of the graphene strain-energy band effect". This nanogenerator is expected to have potential applications in active sensors and sustainable power source.

The newly developed triboelectric nanogenerators (TENGs) provide an excellent approach to convert mechanical energy into electricity, which are mainly based on the coupling between triboelectrification and electrostatic induction. The TENG has the potential of harvesting many kinds of mechanical energies such as vibration, rotation, wind, human motion, and even water wave energy, which could be a new paradigm for scavenging large scale energy. It also demonstrates a possible route towards practical applications for powering electronic devices. This paper presents a comprehensive review of the four modes of TENGs: vertical contact-separation mode, in-plane sliding mode, single-electrode mode, and free-standing triboelectric-layer mode. The performance enhancements of TENGs for harvesting energy as a sustainable power source are also discussed. In addition, recent reports on the hybridized nanogenerator are introduced, which may enable fully self-powered electronic devices. Finally, the practical applications of TENGs for energy harvesting are presented.

Thermoelastic constitutive equations are derived for a material undergoing solidification or hardening as the result of a chemical reaction. The derivation is based upon a two component model whose composition is determined by the degree of hardening, and makes use of strain-energy considerations. Constitutive equations take the form of stress rate-strain rate relations, in which the coefficients are time-dependent functions of the composition. Specific results are developed for the case of a material of constant bulk modulus which undergoes a transition from an initial liquidlike state into an isotropic elastic solid. Potential applications are discussed.
