Laser-induced breakdown spectrometry (LIBS) has been successfully developed to quantify thorium (Th) and uranium (U) in solution using membrane-based filter paper as a sample support. The is easy handle the entire analysis process takes only few minutes for each sample. method provides practical approach fast sensitive determination of actinides aqueous solutions LIBS. We obtained calibration curves U Th individually well mixture. observed that quantification trace levels bulk amount was not...
Simultaneous cloud point extraction of uranium and thorium in aqueous samples with the highest reported efficiencies preconcentration factors.
Glass forensics utilizing major elements from external PIGE and trace INAA in conjunction with principal component analysis.
Abstract Eucalyptol (EU) is a monoterpenoid found as an active compound of many plants such bay leaves, cardamom and also major constituent in eucalyptus oil. Although the anticancer activity eucalyptol has been reported few cancer cell lines, its effect on tumor metastasis not studied so far. Here, we have shown that EU anti-metastatic against skin cells vitro vivo. decreases migration invasion cells. Further, it reduces expression mesenchymal markers vimentin, snail, slug, twist, induces...
LIBS (Laser Induced Breakdown Spectroscopy) for simultaneous multielement quantification of nuclear waste glass using a spectral modification based PLSR approach.
We report spectroscopic studies on plasma electron number density of laser-induced produced by ns–Nd:YAG laser light pulses an aluminum sample in air at atmospheric pressure. The effect different energy and the wavelengths were compared. experimentally observed line profiles neutral have been used to extract excitation temperature using Boltzmann plot method, whereas has determined from Stark broadened as well Saha–Boltzmann equation (SBE). Each approach was also carried out Al emission Mg...
LIBS has been developed for the quantification of platinum group metals (PGM), namely Pd, Rh and Ru in simulated high level liquid nuclear-waste (SHLLW) samples to provide an alternative analytical approach other techniques. Calibration curves were obtained using purity solutions individual PGMs validated PGM as well their mixtures. The amounts present SHLLW both presence absence uranium determined. results agreed with expected values when concentration was up 700 ppmw, while positive bias...
Abstract An example of an aggregation‐induced emission enhancement (AIEE)‐active new naphthalene appended Schiff base ( H 2 L ) as Al 3+ ion selective fluorescent sensor has been successfully designed and synthesized. showed turn‐on fluorescence at high concentration in DMF only, low DMF‐H O mixtures having water content (more than 20%). But very DMF/H solutions with fraction (f w ≤ 20%), the was turned ON presence ions, which helps to detect ions 4.9×10 −7 M selectivity solution without any...
