Even colloidal polytypic nanostructures show promising future in band-gap tuning and alignment, researches on them have been much less reported than the standard nano-heterostructures because of the difficulties involved in synthesis. Up to now, controlled synthesis of colloidal polytypic nanocrsytals has been only realized in II-VI tetrapod and octopod nanocrystals with branched configurations...

Heavy atom nanoparticles have high X-ray absorption capacity and near infrared (NIR) photothermal conversion efficiency, which could be used as radio-sensitizers. We hypothesized that concave PtCu octopod nanoframes (OPCNs) would be an efficient nanoplatform for synergistic radio-photothermal tumor ablation. Methods: In this study, we newly exploited a folic acid-receptor (FR) mediated photothe...

This paper describes experiments in which neural network control architectures were evolved in minimal simulation for an octopod robot. The robot is around 30cm long and has 4 infra red sensors that point ahead and to the side, various bumpers and whiskers, and ten ambient light sensors positioned strategically around the body. Each of the robot's eight legs is controlled by two servo motors, o...

The skin of Octopus vulgaris consumes considerable quantities of oxygen in vitro, averaging 4.55×10−5±1.80×10−5 ml mm−2 h−1 (mean ± S.D.), if a flow is maintained over the skin sample (N=32). The consumption is higher still in vivo, 11.36×10−5±2.73×10−5 ml mm−2 h−1 (N=8), suggesting an additional net import of oxygen through the skin when the blood system is intact. If a substantial boundary la...

Despite the abundance of octapodal species and their evolutionary importance in originating terrestrial locomotion, the locomotion mechanics of spiders has received little attention so far. In this investigation we use inverse dynamics to study the locomotor performance of Grammostola mollicoma (18 g). Through 3-D kinematic measurements, the trajectory of the eight limbs and cephalothorax or ab...
