Slip casting porous silicon nitride for high‐temperature radar frequency radomes

International Journal of Applied Ceramic Technology, EarlyView.
Abstract Silicon nitride (Si3N4) is a promising candidate for ceramic radar frequency (RF) radomes. In this study, suspensions have been developed to slip cast Si3N4 for RF windows utilizing 6 wt.% yttrium oxide (Y2O3)‐2 wt.% aluminum oxide (Al2O3) and 5–15 wt.% ytterbium oxide sintering aids.

Effect of WC addition on the mechanical properties and oxidation resistance of ZrB2/SiC‐based UHTCMCs

International Journal of Applied Ceramic Technology, EarlyView.
Abstract The sintering behavior, mechanical properties, and oxidation resistance of carbon fiber reinforced ZrB2/SiC/WC composites were investigated. Sintering was carried out between 1800 and 2000°C via hot pressing at 40 MPa. WC was completely consumed in the process, and the resulting microstructure was characterized by the formation of Zr1−xWxC ...

Narrowing the “Digital Divide”: The Role of Fixed and Mobile Infrastructure

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT We study the substitution between fixed and mobile broadband services in South Africa using survey data on 134,000 individuals collected between 2009 and 2014. In our discrete‐choice model, individuals choose fixed or mobile voice and data services in a framework that allows these services to be considered substitutes or complements.

A very picky eater: Species‐level prey selection in the endangered Rhone streber [Zingel asper (L. 1758)]

Journal of Fish Biology, EarlyView.
Abstract Prey preferences are important drivers of predator–prey interactions and trophic network structure. We present a species‐level selection analysis for the endangered Zingel asper (L. 1758) and its prey within the Baetis (Ephemeroptera) genus.
