This work presents the valorization of Millettia laurentii carpentry sawdust waste into sustainable natural dye for ecological dyeing and functional finishing wool textiles. A simple aqueous extraction method was used to isolate dye, then extracted bio-dye subjected different qualitative quantitative analyses. Wool yarns were dyed in conjunction with metal salts (aluminum sulfate, ferrous coppe...

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used an electron donor to TiO2 nanoparticles and electrolyte transport medium. One of the extracts purple spinach moringa leaves photosensitizer chlorophyll extract or anthocyanin. The nature able absorb light function in DSSC. Making Moringa leaf red after being blended, dried ground into powder. Then powder was mixed ...

INTRODUCTION The purpose of this in vitro study was to evaluate the sealing ability of the readymade temporary filling and hand mixed materials by assessing coronal microleakage. MATERIALS AND METHODS Standardized access cavities were prepared in 80 intact human permanent premolar teeth. They were divided randomly into four experimental groups (n=20). The teeth were restored using one of the ...

in this work, magnetically separable zno-znfe2o4-ppy nanocomposite as an efficient adsorbent was synthesized by two steps. at first, zinc oxide (zno) and znfe2o4 nanoparticles were synthesized using simple and facile precipitation method. then, zno-znfe2o4 mixed oxide was modified by polypyrrole (ppy). the adsorbent was characterized by x-ray diffraction (xrd), fourier transform infrared (ft-ir...

High performance is expected in dye-sensitized solar cells (DSSCs) that utilize one-dimensional (1-D) TiO2 nanostructures owing to the effective electron transport. However, due to the low dye adsorption, mainly because of their smooth surfaces, 1-D TiO2 DSSCs show relatively lower efficiencies than nanoparticle-based ones. Herein, we demonstrate a very simple approach using thick TiO2 electros...
