As devices and circuits scale to ever smaller sizes thermal management in them becomes more important, heat transport across their interfaces plays a crucial role development. While the study of interfacial resistance goes back almost 90 years, its increasing importance has led significant recent progress theory, experiment, simulation. This review chronicles this for solid-solid, solid-liquid, solid-gas interfaces, discusses how tailor minimize resistance, mentions some remaining challenges.
Abstract The demand for flexible conductive materials has motivated many recent studies on polymer–based materials. However, the thermal conductivity of polymers is relatively low, which may lead to serious heat dissipation problems device applications. This review provides a summary fundamental principles transport in and their composites, advancements regulating conductivity. mechanisms up‐to‐date experimental approaches measuring are first summarized. Effective regulation then discussed....
Thermoelectric materials are prepared by developing 3D printing technology. The fabricated Bi0.5Sb1.5Te3 samples exhibit amorphous characteristics and thus show an ultralow thermal conductivity of 0.2 W m−1 K−1. fabrication readily generates bulk thermoelectric any shape, which is not the case with traditional hot-pressing spark plasma sintering methods. As a service to our authors readers, this journal provides supporting information supplied authors. Such peer reviewed may be re-organized...
Highly bendable n-type thermoelectric nanocomposites are successfully developed by embedding metallic Ni nanowires within an insulating poly(vinylidene fluoride) (PVDF) matrix in solution.

A maximum power factor 220 µW m-1 K-2 ZT 0.15 can thus be obtained with 80 wt% at 380 K.
A novel two-dimensional hybrid polymer photocatalyst black-MoO3/polyimide was synthesized by one-pot thermopolymerization of monomers, ammonium molybdate, and thiourea at mild temperatures. Thiourea molybdate as fluxing agents promote the formation black molybdenum oxide (BMO) on polyimide (PI) enhance crystallinity PI. It is confirmed X-ray photoelectron spectroscopy, electron paramagnetic resonance, Fourier transform infrared that strong interaction between BMO PI leads to a Mo-N...

The thermoelectric figure of merit ($ZT$) in narrow conduction bands different material dimensionalities is investigated for carrier scattering models. When the bandwidth zero, transport distribution function (TDF) finite, not infinite as previously speculated by Mahan and Sofo [Proc. Natl. Acad. Sci.
