Control of heat transport at the nanoscale is crucial for many technologies, including thermoelectricity. We have demonstrated by computer simulation of a toy model, that it is possible to design highly ordered systems with thermal conductivities lower than those of completely disordered structures ...

Lithium ion batteries (LIB) are considered as prime candidates for electric vehicles. Among them, batteries with silicon nanoparticles (SiNPs) based negative electrode are very promising, thanks to their important energy storage capacity, ten times higher than the current ones. But their low ... More »
