Background:Eosin is most widely used synthetic dye belonging to the xanthene group. These dyes are efficient but are hazardous to human and animal health. With the increasing awareness of a green earth, it is advisable to use more of eco-friendly and biodegradable material which can be effectively achieved by the use of natural dyes obtained from plants and other natural sources. Turmeric, available as Curcuma longa (domestic), has long been in use in the subcontinent as a spice and flavoring agent in most food preparations. Its health benefit as a natural antibiotic and anti-inflammatory has been successfully established by several researchers. The intense yellow color imparted by turmeric inspired us to explore its efficacy as a potential alternative for eosin in routine histopathological procedures.Aim:The aim of this was to explore the efficacy of turmeric extract as a stand-alone counterstain for hematoxylin and its comparative assessment with routine H and E staining.Materials and Methods:The rhizomes of C. longa were cut into small pieces, dried and milled. This powder was dissolved into alcohol and centrifuged using a centrifugal machine. The supernatant was then collected with the help of micropipette. This supernatant was used as a counterstain for hematoxylin.Results:The data were analyzed using Mann–Whitney U test with Statistical Package for the Social Sciences version 15.0 (SPSS Inc.,). The P value obtained was statistically insignificant (P > 0.05).Conclusion:Although eosin is the most efficient counterstain for hematoxylin, turmeric can also be used as an alternative for eosin.

A novel Zn(II) mixed-ligand complex, Zn(nba) 2 (meim) 2 (1), synthesized from Zn(NO 3 ) 2 .6H 2 O, nitrobenzoic acid (Hnba) and 1-methylimidazole (meim) is reported. The complex was characterized by elemental analysis, FT-IR, powder and single crystal X-ray crystallography and TGA/DSC. 1 exhibits a tetrahedral geometry for Zn(II), which is coordinated to two carboxylate oxygen atoms from two nba anions and two imidazole nitrogen atoms from two meim molecules. Thermal analysis shows the stability of 1 up to 260°C. The adsorption of eosin yellow (EY) dye on 1 was investigated. The adsorption capacity of 1 for EY amounted to 65.32 mg/g, fitting best into Langmuir isotherm and pseudo second order kinetic models. From DFT studies, it was determined that adsorption is predominantly due to electrostatic, hydrogen bonding and π-π interactions.

“…It can be strongly absorbed by red blood cells and red color, therefore it is commonly utilized in gram staining of many bacterial species. [32] Eosin Y may cause stark skin irritation with redness and pain. [33] Furthermore, it was noticed that just a contact of the dye with the eye can lead to a permanent injury to the cornea.…”

A zinc coordination polymer derived from pyridine‐2,6‐dicarboxylate (PDC), {[Zn2(PDC)2]}n, was successfully prepared via conventional, sonication and microwave‐irradiation methods. The composition and characteristics of the obtained coordination polymers (CPs) were investigated by elemental analysis, TGA/DTA, X‐ray diffraction and spectroscopic techniques. The so obtained CPs were heat‐treated in the air at 600 °C for 2 h to produce ZnO of nanosized particles (NPs). It is of interest to note that the synthesis approach of the precursor greatly affects both the nanoparticle size and the structure of the resulting ZnO NPs. Moreover, the smallest particle size was associated with the sample derived from the ultrasonically prepared precursor. TEM analysis revealed that all samples have sphere‐like morphologies. Structural analysis of the prepared ZnO samples was conducted and compared using Rietveld analysis of their PXRD patterns. Optical band gap calculations based on analysis of the UV–vis spectra of ZnO samples using Tauc's power law were achieved. The highest band gap of 3.63 eV was observed for ZnO sample obtained from the ultrasonically prepared precursor. Furthermore, the photocatalytic activity of ZnO NPs for the removal of Eosin Y color was monitored. The highest removal efficiency was recorded for ZnO originated from the ultrasonically synthesized precursor. Enhancement of removal efficiency that reached 98% was attained in only a period of 8 min. Its recycling test showed that it can be reused without structural changes over four cycling experiments.
