Abstract The goal of this work was to create shape memory polymer blends for the additive manufacturing technology of fused filament fabrication. An iterative approach was taken to develop a binary blend of polycaprolactone (PCL) and thermoplastic urethane (TPU). The composition of equal parts by mass PCL and TPU exhibited the best...

Abstract In this study, Cr–Mo–Cr tri-layer coating with Cr inner layer is designed and compared with the pure Cr coating and Cr–Mo bi-layer coating in steam up to 1600 °C. The Cr–Zr interdiffusion is mitigated effectively by Mo layer. The outer Cr2O3 layer of Cr–Mo coating peels off, and Mo–Zr eutectic reaction occurs above 1500 °C....

Abstract The purpose of this review is to report on the state-of-the-art on the interaction of moisture with natural materials and fabricated biomimetic functional materials, with an emphasis upon the hygro-responsive behaviour of wood. The primary objective is to examine how water sorption affects dimensional behaviour and how knowledge...

Abstract This study utilizes mechanical interlocking as a method to improve the adhesion between the 3D carbon felt foam (CFs) and the epoxy matrix (EP). Hydrothermally, Co3O4 nanoarrays in nanostrips, nanowires, nanoprisms, and nanostars were added to CFs surfaces. Pure 3D carbon fiber-epoxy composites had 62.7% higher storage modulus...

Abstract The impact of medium- and high-entropy alloy fillers (4E MEA- Al0.25Fe0.25Ni0.25Cu0.25, and 5E HEA-Al0.20Fe0.20Ni0.20Cu0.20Ti0.20) on the microstructures and corrosion behaviour of AA5083 plates, joined through the GTAW process, is investigated. MEA and HEA fillers were fabricated using the CCW method, and ER5356 filler was...

Abstract To investigate the possibility of p-type doping of α-SrSi2, a promising as an eco-friendly thermoelectric material, the energy changes of substitutions of the Si site of α-SrSi2 by group 13 elements were evaluated using first-principles calculations. It is found that Ga doping was the most energetically favorable dopant...
