Frafra potato (Solenostemon rotundifolius) is an underutilized climate-resilient tuber crop commonly cultivated in the tropics. Different accessions have been identified and bred to broaden its application food. This study characterized starches extracted from ten accessions, Ghana (released) Burkina Faso (unreleased), terms of yield, physicochemical, microstructural characteristics. The did no...

Abstract The focus of this research was to investigate the effects graphene oxide (GO) on microscopic composition, structure, pore size, and mechanical properties GO-reinforced cement composites. Furthermore, explored thermal behavior mortar at different elevated temperatures (250, 500, 750, 1,000°C). This study considered three sets composites with 0.1, 0.2, 0.3 wt% GO (by weight cement); wate...

In this paper, an ultrasonic shear wave reflection method was adopted to mimic the microstructural evolution of hydrating Portland cement pastes with different water/cement-ratios (0.35, 0.5 and 0.6) cured under a constant temperature of 25°C. The reflection coefficient measured with this technique was correlated to microstructural parameters of the cement pastes. The application of numerical s...

Abstract This study focuses on characterizing the microstructural evolution of aluminum alloy 7075 in friction extrusion process under different forces and die angles. Depending these conditions, two fundamentally types are found, showing significant differences characteristics evolution. One is associated with high force low angle, leading to fully recrystallized wires average grain size aroun...
