The plasmodium of Physarum polycephalum is a large single cell visible with the naked eye. When inoculated on a substrate with attractants and repellents the plasmodium develops optimal networks of protoplasmic tubes which span sites of attractants (i.e. nutrients) yet avoid domains with a high nutrient concentration. It should therefore be possible to program the plasmodium towards determinist...

Nanoporous Pt/TiO2 micro-particles were synthesized via an aerosol assisted co-assembly (AACA) route. Aerosol droplets were produced from a colloidal mixture of 5 nm Pt and 20 nm TiO2 nanoparticles, which formed spherical micro-aggregates of Pt and TiO2 with average diameter of around 1.2 μm. The resulting composite micro-particles have very open structure with pore sizes ranging from 20 to 200...

A novel electrode modified with silver nanoparticles was fabricated. It is found that the reducibility of silver nanoparticles is higher than for bulk silver by comparing a silver nanoparticles modified electrode with a silver micro-disk electrode. When SCN was added, a new oxidation peak occurred and the anodic peak current of silver nanoparticles decreased. The new anodic peak current is prop...

344 Abstract− Silver nanoparticles were synthesized by micro emulsion route in W/S ratio of 5 at room temperature. X-ray diffraction (XRD) pattern reveals FCC structure of Ag nanoparticles. Spherical shape of Ag nanoparticles of average particle size 5.0 to 12.0 nm were observed by transmission electron microscopy. FTIR spectra confirmed the presence of Ag−O bonding. Thermal studies were carrie...

A simple precipitation process followed with the heat treatment was developed to synthesize ZnO micro-tubes by self-assembly of nanoflakes composed of nanoparticles. The resulting ZnO micro-tubes demonstrated excellent photocatalytic performance in degrading methylene blue (MB) under UV illumination. It was found that NH4+ ion played a critical role in directing the assembly of the nanoflakes t...

Micro- and nanomechanical resonators are widely being used as mass sensors due to their unprecedented mass sensitivity. We present a simple closed-form expression which allows a fast and quantitative calculation of the position and mass of individual particles placed on a micro or nano string by measuring the resonant frequency shifts of the first two bending modes. The method has been tested b...

Pine needle-like Pd micro/nano-leaves have been synthesized by a facile, template-free electrochemical method. As-synthesized Pd micro/nano-leaves were directly electrodeposited on an indium tin oxide substrate in the presence of 1.0 mM H2PdCl4 + 0.33 M H3PO4. The formation processes of Pd micro/nano-leaves were revealed by scanning electron microscope, and further characterized by X-ray diffra...

This article takes into consideration a new field of research called Nanopathology and describes the fundamentals of this new discipline. The paper is divided into three main sections: the in-vitro and in-vivo experiments with 5 types of nanoparticles, and the clinical pieces of evidence of the presence of particulate matter in human pathological tissues affected by diseases of unknown origin. ...
