In a dye-sensitized solar cell (DSSC), the amount of light absorption dependson the design of the pigments, which determines the strength of light absorption and theoptical range of the cell. In this paper, we have constructed and studied two fairly similarpattern of DSSCs in structure. The thickness of TiO2 used for both cells is taken to be 2μm. We have used an industrial N719 dye for one of ...

Four natural dyes were extracted from different fruits used in the Dye-sensitized solar cell (DSSC). It includes ber, blackberry, black grapes, and blueberry by individual dye or combined with other dyes. The solution's absorption spectra extended to whole visible region 200–750 nm. FTIR spectroscopy was employed identify possible functional group vibrations responsible for dyes' chemical activ...

Berries such as blueberry, blackberry and raspberry possess several biological activities including antimicrobial and nutritional effects. In this study, the antimicrobial activities of blackberry (Rubus fruticosus) juice against foodborne pathogens including Listeria monocytogenes, Salmonella Typhimurium and Escherichia coli O157:H7 were investigated. Inhibition of growth of these foodborne pa...

Background: Blackberry is a seasonal harvested fruit that is also very fragile and perishes quickly. A comparative study was conducted to find out influence of cold storage on physicochemical parameters of wild and cultivated blackberry over a period of 12 days. Methods: The plant materials were composed of the blackberry fruit, including a compound of cultivated blackberry (Rubus spp.), and w...

The Blackberry operating systems with its limited applications. In its application world are emerging to be the most efficient devices. The android operating systems which involves a variety of applications, Blackberry still continues to be the addiction of most of the peoples as indicated by some of the studies. However some of the studies also present the problems witnessed by its users. Rese...

in this study, a functional colorant, berberine, extracted from berberis vulgaris wood was applied onto wool fiber using the extract of roots of rumex hymenosepolus as biomordant. the effect of treatment variables on the color strength of dyed fibers was examined. the fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. dyed samples were tested for antiba...

Natural dye extracted from aerial parts of Barleria prionitis and different kinds of textile fabrics dyed with the natural dye were investigated for their antifungal activity. Antifungal activity of natural dye and dyed fabrics was assessed against standard strains of five fungi namely Aspergillus flavus, A. niger, A. parasiticus, Fusarium moniliforme and Penicillium canescens using agar-we...

blackberry diversity is high in iran due to its wild and natural populations especially in south of caspian sea. however it has not been investigated before. the goal of this work was to evaluate some wild populations of black berry in mazandaran province of iran. at first, region and then location of blackberries plants identified and the traits of leaf, stem, spin, flower, fruit quantity and ...

In this work, a new and natural food product, stalked barnacle (Pollicipes Pollicipes) pâté enriched with blackberry, was developed to valorise the rejected barnacle. To evaluate addition of blackberry fruits (Rubus ulmifolius Schott.) as preservative on quality, four sample groups were considered: negative control without synthetic additive (CTR), positive butylated hydroxytoluene (BHT), group...

In contrast to the well-described various biological effects of grape wines, the potential effects of commonly consumed blackberry wine have not been studied. We examined in vitro antioxidant and vasodilatory effects of four blackberry wines and compared them with the effects of two red and two white grape wines. Although some blackberry wines had lower total phenolic content relative to the re...
