DSSC technology based on natural dyes still constitutes a tempting alternative to explore. Besides the ease of extraction, most fulfill characteristics be applied as sensitizers. The presented results summarize exploration features several southern dyes, mostly coming from Antarctic region. explored pigments showed good absorption capacity within visible region light spectra, and their molecule...

Dyes are a type of pollutant that have been discharged into water streams by various industries and had harmful effects on the environment human health. Therefore, present work was directed to recycle acrylic fibers waste be used as an adsorbent exclude dyes such methylene blue (MB) Congo red (CR) from dyes-polluted wastewater. Acrylic converted membrane followed chemical grafting with p-phenyl...

Poly(A) has significant relevance to mRNA stability, protein synthesis and cancer biology. The ability of two phenothiazinium dyes azure A (AA) and azure B (AB) to bind single-stranded poly(A) was studied by spectroscopic and calorimetric techniques. Strong binding of the dyes and the higher affinity of AA over AB were ascertained from absorbance and fluorescence experiments. Significant pertur...

Scientists have expressed continued interest in the development of microsensor technology that can indicate toxicity that occurs within a cell after a chemical challenge. One of the more useful approaches of microsensor technology is the application of fluorescent spectroscopy to indicate early-stage injury with optimal specificity and decreased background interference. If the toxicity is detec...

In the search for functional organic biomaterials, leather constituted by collagen fibers was coated with a conducting polymer, polypyrrole. The coating carried out during oxidation of pyrrole in an aqueous solution poly(N-vinylpyrrolidone) presence five dyes: crystal violet, neutral red, methyl orange, acriflavine, and methylene blue. This technique ensures uniform polypyrrole incorporation dy...

Influence of alkali and temperature were studied on dyeing of cotton fabric with bi-functional Fluoro Chloro Pyrimidene (FCP), bi-functional Monochlorotriazine-Vinyl Sulphone (MCT-VS) and mono functional Monochlorotriazine (MCT) reactive dyes. For this analysis single joursey knitted fabrics were taken. The selected dyestuffs were Drimarene Yellow K-2R (FCP), Drimarene Red CI-5B (MCT-VS) and Dr...

The excited-state properties in a series of coumarin solar cell dyes are investigated with a long-range-corrected (LC) functional which asymptotically incorporates Hartree-Fock exchange. Using time-dependent density functional theory (TDDFT), we calculate excitation energies, oscillator strengths, and excited-state dipole moments in each of the dyes as a function of the range-separation paramet...

Many researchers are accustomed to imaging cellular components with a limited palette of fluorescent dyestypically red, green, and blue. Wei Min and colleagues have now reported the development of a refined imaging technique along with the concurrent synthesis of finely tuned dyes that brings the number of colors available for cellular imaging to an amazing 24 hues (Nature 2017, 544, 465−470)....
