Nucleobase analogs 5-methylisocytosine ((Me)isoC) and isoguanine (isoG) form a non-natural base pair in duplex nucleic acids with base pairing specificity orthogonal to the natural nucleobase pairs. Sequencing reactions were conducted with oligodeoxyribonucleotides (ODNs) containing d(Me)isoC and disoG using modified pyrosequencing and dye terminator methods. Modified dye terminator sequencing ...

In the present work, the effect of initial pH of methylene blue solution on the kinetics of dye sorption from synthetic aqueous solution by a natural waste material namely: orange peels, was studied. Kinetic data were measured in batch conditions. Methylene blue uptake was time contact and solution initial pH dependent. Maximum dye sorption was found to occur at initial pH 9. Two simplified kin...

Cost and energy payback time in relation to solar cell performances is one of the key parameters considered for mass application. In this research work, a low-cost, easily fabricated, more eco-friendly photovoltaic device was successfully developed using dye synthesized from teak plant leaves. The dye-sensitized (DSSC) made up photoelectrode counter electrodes. prepared by depositing zinc paste...

This study was performed with the aim of investigating the efficiency of the Nano photocatalytic of ultraviolet and titanium dioxide compound and rice husk silica adsorbent (UV/TiO2/RHS) in removal reactive red 198 dye from synthetic aqueous solutions. The removal of reactive red 198 dye was done in batch reactors with a volume of 250 ml using RHS deposited by titanium dioxide in the...

The aim of this study is the improvement of the photostability of several natural anionic dyes, carmine (CM), carthamus yellow (CY), and annatto dye (ANA), by complexation with hydrotalcite. The composite of the dyes and hydrotalcite is prepared by the coprecipitation method. CM is successfully intercalated in the hydrotalcite layer when the amount of introduced CM is large. The photostability ...

Natural dyes have been used for staining wool, silk, carpet and cotton in addition to their uses in staining of tissue microscopical sections. The binding of dyes to textile products has been studied for many years, but is sti l l not fully understood. Less is known about the interaction between the dye and tissue components. Black mulberry (Morus nigra) fruits have strong staining activity and...
