Electronic speckle pattern interferometry and related techniques using digital still cameras
(© 2007 Nova Science Publishers, Inc., 2007)
Construction and operation of a dispersive laser raman spectrograph using interference filter
(© 2008 Journal of Bangladesh Academy of Sciences, 2008)
A dispersive laser Raman system was designed and constructed using a helium-neon (He-Ne) laser as an excitation source, and an interference filter in the reflection mode for Raleigh filtering instead of the more common ...
Generating near-field fresnel diffraction patterns by iterative fresnel integrals method: a computer simulation approach
(© 2012 Nova Science Publishers, Inc., 2012-12)
Recently the concept of computer-based virtual experiments in all branches of physics has generated wide spread interests among the researchers. In this Chapter, we describe the Iterative Fresnel Integrals Method (IFIM), ...
Determination of ratio of unsaturated to total fatty acids in edible oils by laser Raman spectroscopy
(© 2009 Asian Network for Scientific Information, 2009)
In this study, a homemade laser Raman spectrometer was used to examine the Raman spectra of different edible oils, such as canola, corn, soybean, sunflower, palm and coconut oils. To avoid severe fluorescence effects which ...
Identification of multiple rare earths and associated elements in raw monazite sands by laser-induced breakdown spectroscopy
(© 2010 Elsevier Ltd., 2011-02)
Laser-induced breakdown spectroscopy (LIBS) is an emerging and promising tool for rapid and efficient elemental analysis. We used the LIBS technique to analyze the raw monazite sands collected from the beaches in southern ...
Survey of the water bodies for ecotoxic metals by laser-induced breakdown spectroscopy
(© 2015, Mary Ann Liebert, Inc., 2015-04)
Laser-induced breakdown spectroscopy (LIBS) was applied to the analysis of ecotoxic metals in water samples, an issue of major importance for environmental monitoring. Pollution in water bodies around Dhaka city, Bangladesh ...
Fabrication of silver nanoparticles by laser ablation technique: their characterization and uses
(© 2013 Nova Science Publishers, 2013)
Nano structure materials have generated much interest in recent years.
Nanotechnology involves the fabrication of particles at the nano scale level and
subsequent use of those nano structure materials for better, more ...
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). ...
