The influence of basalt fabric on the tensile mechanical properties and the impact resistance of green epoxy resin was investigated. Composites with parallel arrangement of insert yarns had better properties than in the case of their perpendicular arrangement. The properties were also influenced by the number of layers of the fabric. The tensile strength and impact resistance of the composites were...
Needleless electrospinning is expected to produce nanofibers with a large productivity. In this study, a sprocket wheel disk was used as spinneret to electrospin nanofibers. The sprocket disk shows reliable electrospinning process. In comparison with the conventional disk spinneret, which has no sprocket on the edge, the sprocket wheel produced more uniform nanofibers with smaller fiber diameter....
Previous research has shown that the humanoid NAO robot can enhance learning as well as improve communication in children with intellectual disabilities. However, most special needs schools cannot afford the humanoid NAO robot due to high costs. Could a cheaper non-humanoid Lego Mindstorm robot be an alternative way of achieving the same learning objectives as the humanoid NAO robot? A single case...
