Because the properties of thermoelectric (TE) materials are strongly dependent on temperature and differ considerably, segmented TE legs composed of multiple stacked TE materials have been investigated to provide efficient operation of TE devices. Ho

Summary: A thermoelectric device is a heat engine that directly converts heat into electricity. Many materials with a high figure of merit ZT have been discovered in the anticipation of a high thermoelectric efficiency. However, there has been a lack

Advection and cross-diffusion terms are obtained as dispersal strategies of biological species. The focus of the paper is their connection to a given population dynamics. In particular, meaningful parameter regimes as biological dispersal are obtaine

Summary: For over half a century, the development of thermoelectric materials has based on the dimensionless figure of merit zT, assuming that the efficiency is mainly determined by this single parameter. Here, we show that the thermoelectric convers

We consider competition systems of two species which have different dispersal strategies and interspecific competitive strengths. One of the dispersal strategies is random dispersal and the other is a Fokker-Planck diffusion whose motility is piecewi

The super- and subsoltuion theory is developed when the nonlinear reaction function is discontinuous at stable steady states. The solution is defined in a weak sense using a notion of set-valued in...
A thermoelectric generator converts a temperature difference into electrical energy. Its energy conversion efficiency is determined by the steady-state temperature distribution inside the generator. By assuming the thermoelectric material in the gene

There have been significant developments in the enhancement of the thermoelectric (TE) performances of p-type PbTe compounds; however, the TE performances of n-type compounds are not comparable with those of p-type ones. For optimizing the high perfo

In developing thermoelectric generators, optimizing interfaces between thermoelectric materials and contacting electrodes is a crucial step. Among the tested electrodes for Mg2(Si,Sn)-based generators, Ag shows good adhesion, controllable interfaces
