Evolutionary computation for image processing is an encouraging research area. Transmission electron microscopy (TEM) images when used to characterize metallic and non-metallic nano-particles (size, morphology, structure, or composition), need such advanced image processing algorithms. This paper presents an efficient evolutionary computational method, particle swarm optimization (PSO), for aut...

synthesis, characterization, spectral and theoretical calculations of sodium tetrafluoroborate (iii) (stfb) has been studied in this research. sodium tetrafluoroborate (iii) was synthesized by a sonochemical method and characterized by ir, uv/vis, 11b-nmr and mass spectrometer techniques. the nano compound was characterized by scanning electron microscopy (sem), x-ray powder diffraction (xrd) a...

The term microstructure refers to the complete internal structure of a material on the micro, nano and atomic scales. On one hand, it records the entire history of a material’s processing and structuring (casting, forming, heat treatments, but also crystal growth, etc.) through its phase composition, defect structure and morphology. On the other hand, all properties (stiffness, formability, con...

Nano-networks are the interconnection of nano-machines and as such expand the limited capabilities of a single nano-machine. Several techniques have been proposed so far to interconnect nano-machines. For short distances (nm-mm ranges), researchers are proposing to use molecular motors and calcium signaling. For long distances (mm-m), pheromones are envisioned to transport information. In this ...

Nanospray desorption electrospray ionization (nano-DESI) combined with high-resolution mass spectrometry (HR-MS) is a promising approach for the detailed, molecular-level chemical characterization of atmospheric organic aerosols (OA) collected in laboratory and field experiments. The nano-DESI technique possesses distinct advantages of technical simplicity, enhanced sensitivity, and signal stab...
