Purpose Protoplasmic tubes of Physarum polycephalum, also know as Physarum Wires (PW), have been previously suggested as novel bioelectronic components. Until recently, practical examples of electronic circuits using PWs have been limited. These PWs have been shown to be self repairing, offering significant advantage over traditional electronic components. This article documents work performed ...

The ability of Lepidoptera, or butterflies and moths, to drink liquids from rotting fruit and wet soil, as well as nectar from floral tubes, raises the question of whether the conventional view of the proboscis as a drinking straw can account for the withdrawal of fluids from porous substrates or of films and droplets from floral tubes. We discovered that the proboscis promotes capillary pull o...

A practical theoretical framework is presented for designing and classifying minimally strained nucleic acid nanotubes. The structures are based on the double crossover motif where each double-helical domain is connected to each of its neighbors via two or more Holliday-junction-like reciprocal exchanges, such that each domain is parallel to the main tube axis. Modeling is based on a five-param...

The photocatalytic antibacterial properties of anodic titanium oxide (ATO) nanotubes in the anatase structure derived from annealing at 450°C or 550°C N-doping treatment were tested on Escherichia coli under UV-A, visible light illumi-nation, and dark conditions. Under UV-A illumination conditions, most cases, E. cultures containing ATO different treatments showed either no slight differences t...

In internal combustion engines, only about a third of the total fuel input energy is converted into useful work. If the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. The main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing ce...
