Modeling of concentrating solar thermoelectric generators
TL;DR: In this paper, the possibility of solar thermoelectric generators (STEGs) being used as the power block in concentrating solar power systems has been discussed, and it has been shown that using existing skutterudite and bismuth telluride materials, concentrating STEGs can have efficiencies exceeding 10% based on a geometric optical concentration ratio of 45.

TL;DR: It is shown that Au nanomesh on a slippery substrate is fatigue-free when cyclically stretched to large strains (>100%).
Journal ArticleDOI
Subwavelength waveguide for visible light
J. Rybczynski,Krzysztof Kempa,Andrzej Herczynski,Yayu Wang,Michael J. Naughton,Zhifeng Ren,Zhongping Huang,Dong Cai,Michael Giersig +8 more
TL;DR: In this article, the authors demonstrate transmission of visible light through metallic coaxial nanostructures many wavelengths in length, with coaxial electrode spacing much less than a wavelength, and they have thus achieved a faithful analog of the conventional coaxial cable for visible light.

Robust Hydrogen-Evolving Electrocatalyst from Heterogeneous Molybdenum Disulfide-Based Catalyst
TL;DR: Molybdenum disulfide-based layered materials are promising electrocatalysts for hydrogen production from water electrolysis if their catalytic performance can be further improved by increasing the...

Phonon scattering by nanoscale twin boundaries
TL;DR: In this article, three different kinds of InSb specimens with microscale grains, nanoscale grains, and nanoscales grains with nanotwins were prepared in order to resolve the issue, and they unambiguously show that phonons can indeed be scattered by twin boundaries.
