Ab Initio Thermoelectric Transport Calculations of Alloyed Half‐Heuslers
Advanced Science, EarlyView.The effect of alloying on the electronic transport of half‐Heusler thermoelectric materials is explored using a fully ab initio approach. A novel method is developed that combines calculations of alloyed supercells with Boltzmann transport, considering the full energy and momentum dependent scattering processes from first principles extracted ...

Maximum Sound Absorption Coefficient of a Fiber Assembly
Journal of the Textile Machinery Society of Japan, 1964 To determine the most suitable porosity of a fiber assembly used as a sound absorbent, we measured the sound absorption coefficients of fiber assemblies having air spaces behind them by the standing wave method and investigated their sound absorption characteristics.

A Device for Direct Measurement of Sound Absorption Coefficients [PDF]
The Journal of the Acoustical Society of America, 1931 This paper describes a small scale device for direct comparison of the intensity of sound reflected from a surface of unknown coefficients with that reflected under identical conditions from surfaces whose coefficients have been determined by reverberation methods. It consists of means for producing sound of fixed intensity and frequency at an angle of

Advanced Science, EarlyView.A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.
