TL;DR: In this article, ultrathin tungsten-doped nickel iron layered double hydroxide (Ni-Fe-W LDH) nanosheets, which are composed of nanoparticles with size of 2 to 6 nanometers, have been directly grown on nickel foam (NF) using a facile and scalable water bath reaction.
Journal ArticleDOI
Optimizing the thermoelectric performance of low-temperature SnSe compounds by electronic structure design
TL;DR: In this paper, the electronic structures of SnSe are calculated using the density functional theory, and the electro- and thermo-transport properties upon carrier density are evaluated by the semi-classic Boltzmann transport theory, revealing that the calculated ZT values along the a and c-axes below 675 K are in agreement with reported values, but that along the b-axis can be as high as 2.57 by optimizing the carrier concentration to n ∼ 3.6 × 1019 cm−3.

TL;DR: A new approach to polymer identification by laser-induced breakdown spectroscopy with adjusting spectral weightings (ASW) was developed in this work aiming at improving the identification accuracy.
Journal ArticleDOI
Effect of temperature, pressure, and gas ratio of methane to hydrogen on the synthesis of double-walled carbon nanotubes by chemical vapour deposition
TL;DR: In this article, double-walled carbon nanotubes (DWCNTs) were synthesized by chemical vapour deposition using Fe-Mo catalyst supported on magnesium oxide particles.
