TL;DR: In this paper, the carbon felt was modified by pyrolysis of Ir reduced from H 2 IrCl 6. ac impedance and steady-state polarization measurements showed that the Ir-modified materials have improved activity and lowered overpotential of the desired V(IV)/V(V) redox process.

TL;DR: In this article, an improved design of wavy microchannel heat sink with changing wavelength or/and amplitude along the flow direction is proposed, and the thermal resistance R and the maximum bottom wall temperature difference Δ T b,max for the new design are compared with those for the straight and the original wavy design under a constant pumping power.

TL;DR: In this paper, a 3D microchannel heat sink (MCHS) using nanofluids is investigated by a numerical study, and the authors suggest that the best heat transfer enhancement can be obtained by using a system with an Al 2 O 3 -water-water-nano-cooled MCHS, and that using base fluids with lower dynamic viscosity (such as water) and substrate materials with high thermal conductivity enhance the thermal performance.

TL;DR: In this article, a general, three-dimensional numerical model of thermoelectric devices with consideration of coupling of temperature field and electric potential field was developed to figure out the performance of TECs with the temperature dependent thermal conductivity, electric conductivity and Seebeck coefficient of semiconductor materials.

TL;DR: Two nanoparticle dissipation modes, the bulk Dissipation mode and the local dissipation mode, are proposed to resolve the uncertainties related to the various types of dynamic wetting mechanisms reported in the literature.
