The application of laser-induced breakdown detection (LIBD) as a new and powerful particle-analyzing technique for the determination of solubility data by monitoring initial colloid generation, when the metal ion concentration just exceeds the solubility at a given pH value, is investigated. Laser-induced breakdown spectroscopy (LIBS) is used for selective analysis of an aqueous suspension of l...

The aim of this work was to analyze the variety of soil by laser-induced breakdown spectroscopy (LIBS) coupled with chemometrics methods. 6 certified reference materials (CRMs) of soil samples were selected and their LIBS spectra were captured. Characteristic emission lines of main elements were identified based on the LIBS curves and corresponding contents. From the identified emission lines, ...

Abstract To reduce or completely remove the viewing angle dependence of liquid crystal (LC) displays and devices, we have recently introduced a new electrode structure for LC displays. This has openings (holes) in pixel (PixE) generating fringe electric field with azimuthal degenerated distribution lines around each hole, resembling fountain. Such is promoting azimuthally switching molecules th...

Final Report: ARO Terrestrial Research Program, Methodologies and Protocols for Characterization of Geomaterials Report Title The third and final year of this project continued to focus on the use of laser-induced breakdown spectroscopy (LIBS) for the analysis of geomaterials. LIBS was utilized for geochemical fingerprinting of an extensive suite carbonate minerals, including those of biogenic ...

Introduction: Measurements of elemental composition of Mars' rocks and soils have been limited to a very few missions, most notably Vi-king and Mars Pathfinder [e.g., 1,2], and to the martian meteorites. While the Mars Exploration Rover (MER) missions to be launched later this year represent a significant step forward, many of the key questions of today will remain for future missions to be ans...

Standoff laser induced breakdown spectroscopy (LIBS) has previously been used to classify trace residues as either hazardous (explosives, biological, etc.) or benign. Correct classification can become more difficult depending on the surface/substrate underneath the residue due to variations in the laser-material interaction. In addition, classification can become problematic if the substrate ma...

This paper describes the semi-quantitative analysis of metal nanoparticle ink using laserinduced breakdown spectroscopy (LIBS). LIBS can be used to obtain information about the density and chemical composition of silver particles or copper particles, even ultrafine particles. Metal particles have been attracting much attention because of their increased use in new micro-nano technologies. In th...

Carbon-coated SnO(2) nanorod array directly grown on the substrate has been prepared by a two-step hydrothermal method for anode material of lithium-ion batteries (LIBs). The structural, morphological and electrochemical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electrochemical measurement. Wh...

The past decades have witnessed the development of many technologies based on nanoionics, especially lithium-ion batteries (LIBs). Now there is an urgent need for developing LIBs with good high-rate capability and high power. LIBs with nanostructured electrodes show great potentials for achieving such goals. However, the nature of Li-ion transport behaviors within the nanostructured electrodes ...
