Abstract Eosin Y (EY) is an acidic xanthene dye which is mainly used in food stuff and biological staining. Various analytical methods have been reported for the utility of this dye in the quantitative determination of several pharmaceutical compounds, heavy metals in addition to some surfactants and proteins. Most of the applied methods were based on the formation of association complexes between eosin Y and the target analytes in buffered aqueous solutions. The present article represents a comprehensive review for the use of eosin Y as a probe in analytical chemistry.

Quantitative determination of heavy metals; Fe, Zn, Co, Pb and Ni in Mango fruit of Nepali origin, locally sourced was carried out. Fifteen Mango samples were collected by random sampling method, converted into analyte sample by standard method and analyzed by using Atomic absorption spectrometric method. The amount of heavy metals Fe, Zn, Co and Ni present in sample was, 0.570±0.48, 0.510±0.031, 0.431±0.021, 0.106±0.003 mg/kg respectively. The results indicated the concentration of Zn & Co were higher (WHO 0.320 & 0.05), and the concentration of Nickel (Ni) was below the maximum permissible limit issued by WHO. The concentration of the Lead (Pb) was found below the detection limit of the instrument used.

In the second of this two-part series for the MRS Bulletin, we present the most commonly used tools for the quantitative determination of structure and chemistry in thin films. The physics of thin films is at a stage during which one encounters phenomena that have a fragile dependence on the structure and chemical properties of the interface; the field, therefore, is at a stage during which quantitiative structural and chemical determination at the atomic level is a must. It is the purpose of the December and January issues of the Bulletin to provide a start for researchers interested in the field. Of course, even during the writing of these articles new techniques are being invented and it is therefore impossible to provide a comprehensive review of all techniques being used these days.
