TL;DR: A universal machine-learning scheme using a local similarity kernel, which allows interrogation of catalytic activities based on local atomic configurations is proposed and applied to direct NO decomposition on RhAu alloy nanoparticles.
Abstract: Catalytic activities are often dominated by a few specific surface sites, and designing active sites is the key to realize high-performance heterogeneous catalysts. The great triumphs of modern surface science lead to reproduce catalytic reaction rates by modeling the arrangement of surface atoms with well-defined single-crystal surfaces. However, this method has limitations in the case for highly inhomogeneous atomic configurations such as on alloy nanoparticles with atomic-scale defects, where the arrangement cannot be decomposed into single crystals. Here, we propose a universal machine-learning scheme using a local similarity kernel, which allows interrogation of catalytic activities based on local atomic configurations. We then apply it to direct NO decomposition on RhAu alloy nanoparticles. The proposed method can efficiently predict energetics of catalytic reactions on nanoparticles using DFT data on single crystals, and its combination with kinetic analysis can provide detailed information on stru...

TL;DR: In this paper, an aluminum complex of a phosphoric ester combined with hydrotalcite (NA) was found to be effective for the melt-crystallization of poly( l -lactide) (PLLA) and PLLA/poly( d -lactic) (PDLA) stereo mixture, respectively.

TL;DR: In this article, the thermoelectric properties of the Heusler-type alloys with compositions $0.05$ at around room temperature were investigated. And it was concluded that doping of heavier atoms such as Ge reduces more effectively the lattice thermal conductivity while retaining the low electrical resistivity as well as the large Seebeck coefficient.
Abstract: We report on the thermoelectric properties of the Heusler-type ${\mathrm{Fe}}_{2}{\mathrm{VAl}}_{1\ensuremath{-}x}{\mathrm{Ge}}_{x}$ alloys with compositions $0\ensuremath{\le}x\ensuremath{\le}0.20$. While ${\mathrm{Fe}}_{2}\mathrm{VAl}\phantom{\rule{0.3em}{0ex}}(x=0)$ exhibits a semiconductorlike behavior in electrical resistivity, a slight substitution of Ge for Al causes a significant decrease in the low-temperature resistivity and a large enhancement in the Seebeck coefficient, reaching $\ensuremath{-}130\phantom{\rule{0.3em}{0ex}}\mathrm{\ensuremath{\mu}}\mathrm{V}∕\mathrm{K}$ for $x=0.05$ at around room temperature. Comparison with the ${\mathrm{Fe}}_{2}{\mathrm{VAl}}_{1\ensuremath{-}x}{\mathrm{Si}}_{x}$ system demonstrates that the compositional variation of the Seebeck coefficient falls on a universal curve irrespective of the doping elements (Ge and Si), both of which are isoelectronic elements. The net effect of doping is most likely to cause a rigid-bandlike shift of the Fermi level from the central region in the pseudogap. In spite of a similar decrease in the electrical resistivity with composition of Ge and Si, the thermal conductivity decreases more rapidly for the Ge substitution. It is concluded that doping of heavier atoms such as Ge reduces more effectively the lattice thermal conductivity while retaining the low electrical resistivity as well as the large Seebeck coefficient.
