Counterstains can be of high relevance for the evaluation of immunostaining because cellular details and immunological reactivity are often easier correlated in counterstained tissue sections than in simply immunostained specimens. There are many kinds of dyes in histology. Some are useful for counterstainings while others are not; a careful selection is necessary. Even a given type of dye, f.e...

Abstract Dyes have been widely used by communities for various purposes, such as a compositional ingredient in food, customs, or traditional activities and crafts. The types methods of usage are highly dependent on the presence plants animals found around residential areas there also several exotic species that assimilated come from other ethnic groups. aim this study is to determine produce na...

Natural dye-sensitized solar cells (NDSSCs) have gained considerable attention in the field of solar energy due to their simple fabrication, good efficiency, and low production cost. Natural dyes are environmentally and economically superior to ruthenium-based dyes because they are nontoxic and cheap. However, the conversion efficiency of dye-sensitized solar cells based on natural dyes is low....

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

Natural dyes gained increasing attention due to environmental considerations. Many of the dye plants have also medicinal values. This study aimed to evaluate the effect of 25 plants as dyes and their dyed wool yarns against microorganisms. Prokaryotes were found to be more sensitive to dye extracts than eukaryotic microorganisms and dyestuff from Punica granatum, Berberis vulgaris, Agrimoni...

In this paper, the results of studies of the sorption activity of Salvadora Persica fine particles that were provided from internal natural resources at Iran, with respect to Crystal Violet, Basic Violet-16 and Basic Blue-41 dyes were presented. Thus, Salvadora Persica particles were modified and prepared via particle size decreasing and characterized by CHNS, XRD, SEM and FT-IR analysis. In th...
