Deep-Learning-Aided Extraction of Optical Constants in Scanning Near-Field Optical Microscopy [PDF]
, 2022 Scanning near-field optical microscopy is one of the most effective techniques for spectroscopy of nanoscale systems. However, inferring optical constants from the measured near-field signal can be challenging because of a complicated and highly ...

Cd(II) extraction in PEG(1550)-(NH4)2SO4 aqueous two-phase systems using halide extractants [PDF]
Journal of the Serbian Chemical Society, 2008 The extraction of Cd(II) was studied in an aqueous PEG-(NH4)2SO4 two-phase system, formed from a water-soluble polymer (poly(ethylene glycol), PEG) and an inorganic salt ((NH4)2SO4), in the presence of halide ions. In the absence of a suitable extracting

Extraction of Chromium(III) and Manganese(II) with N, NI-ethylenebis(salicylimine)(H2EBSI) in Acid Medium: Determination of Stability Constant and Thermodynamic Parameters of the Extracted Species [PDF]
Chemical Science International Journal, 2018 In this study, the solvent extraction of chromium(III) and manganese(II) with N, N1- ethylenebis(salicylimine) were carried out from different concentrations of various mineral acids (HCl, HNO3, H2SO4, and HClO4). In the range of analytical concentrations of the acids studied (0.0001-2M), it was discovered that the distribution ratio was highest in 0 ...
