A quick method to determine the impurity content in gold ornaments by LIBS technique
(© 2015 SciTePress, 2015)
Laser induced breakdown spectroscopy (LIBS) and low energy dispersive X-ray fluorescence (ED-XRF) spectrometer, were used to determine the line intensity and concentration ratios of the major impurities (Cu and Ag) with ...
Gold nanoparticles: fabrication by laser ablation technique and their optical and morphological studies
(© 2013 Nova Science Publishers, 2013-01)
Material particles of the size of few nano-meters to couple of hundreds of nano-meters exhibit size and shape dependent properties and the consequent versatility and importance in their use have made them an exciting and ...
Elemental profiling and identification of eco-toxic elements in agricultural soil by laser-induced breakdown spectroscopy
(© 2013 Science and Education Publishing, 2013-05)
Laser induced breakdown spectroscopy (LIBS) was used to determine the elemental content and to detect probable eco-toxic elements in agricultural soil in Gazipur, Bangladesh (latitude: 24.0958° N, longitude: 90.4125° E). ...
Power dependence of size of laser ablated colloidal silver nanoparticles
(© 2010 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2010-11)
Silver nanoparticles have been produced by laser ablation of silver metal in nanopure water without any chemical additives. It has been observed that laser power has a control over the size of the nanoparticles. Increasing ...
Elemental profiling and determination of Ti content of the beach sand samples of Bangladesh using LIBS technique
(© 2010 Elsevier Ltd., 2010-09)
Laser-induced breakdown spectroscopic technique was used to study the elemental profile of beach sand samples of Bangladesh. Apart from Silicon, which is the main elemental constituent of sand, the presence of Li, Na, Mg, ...
Determination of Ca content of coral skeleton by analyte additive method using the LIBS technique
(© 2012 Elsevier Ltd., 2012-09)
Laser-induced breakdown spectroscopic (LIBS) technique was used to study the elemental prole of coral skeletons. Apart from calcium and carbon, which are the main elemental constituents of coral skeleton, elements like Sr, ...
Fabrication of gold nanoparticles in water by laser ablation technique and their characterization
(© 2011 Springer-Verlag., 2011-11)
A colloidal solution of gold nanoparticles in deionized nanopure water was produced by laser ablation technique without the use of any chemical/surfactant. Spectral characterization and morphological studies of these ...
Determination of the ash content of coal without ashing: a simple technique using laser-induced breakdown spectroscopy
(© 2013 American Chemical Society, 2013-07-18)
The bituminous coal samples were analyzed using the technique of laser-induced breakdown spectroscopy (LIBS). The fraction of the ash content of the coal was spectroscopically determined by a technique requiring only two ...
