Abstract:
Triazoloisoquinoline-based organic dyestuffs were synthesized and used in the fabrication of dye-sensitized solar cells (DSSCs). After cosensitization with ruthenium complex, the triazoloisoquinoline-based organic dyestuffs overcame the deficiency of ruthenium dyestuff absorption in the blue part of the visible spectrum. This method also fills the blanks of ruthenium dyestuff sensitized TiO2film and forms a compact insulating molecular layer due to the nature of small molecular organic dyestuffs. The incident photon-to-electron conversion efficiency of N719 at shorter wavelength regions is 49%

Abstract:
Wood specimens were dyed by boiling them in the presence of walnut shells and dye to penetrate the dyestuff into the sample. Specimens prepared from Scots pine, oak, and beech woods were boiled separately in walnut shell, water, and NaOH environment, and the penetration of the dyestuff into the samples was ensured. Sodium hydroxide solution was preferred because it facilitates the dissolution of the hemicelluloses in the wood and the dyestuffs in the walnut shell. Alum was added in other samples to reveal the mordant effect on the adhesion of dyestuffs to wood. Thermogravimetric (TG) analysis

Abstract:
AbstractBetween the 1870s and the 1920s, the dye industry was at the center of claims about the productivity of organic chemistry. Dyestuffs were widely represented as the most complex molecules to find commercial application, and positioned at the center of nationalist projects to establish chemical industry, especially in Britain and the United States. By the later twentieth century, the complex of scientific hopes which surrounded dyestuffs had largely disappeared. In Hans-Jörg Rheinberger’s terms, they had changed from “epistemic things” to, at best, “technical objects,” and lost their fut

Currently electroluminescent devices, operated by alternating current (AC-EL) on film, paper or textile are based on a capacitor with one transparent electrode and one generally non-transparent, highly conductive electrode and a light-emitting dielectric layer in-between.

Those dispersions allow AC-EL-devices illuminating solitary in the colors white, green, blue-green, blue and orange. Blending those pigments leads to numerous

The dyestuffs were biotransformed into colourless substituted amine metabolites in the reactor. The biotransformation was assisted by co-metabolic process.

The colourful past of the late 18th century marquetry furniture has seldom been highlighted. Through ageing and environmental influences, colourful marquetry furniture has lost their original expression. The current knowledge of how Swedish cabinet-makers in the late 18th century used dyes to colour their furniture is limited. Trace of colour has been observed and the use of dyes has been mentioned, but deeper research in this filed is missing. A visual examination and studies of archive documents and previous research have been performed to investigate the colourful past of Gottlieb Iwerssons

Abstract Among the most important polymeric conductors from the technological standpoint (as distinct from molecularly doped polymer films, which constitute the much more commercially important materials used in electrophotography) are the polyanilines. Polyanilines are a family of polymers of the general formula shown in Fig. X. l. These compounds have been known for more than 100 years as aniline blacks and are important dyestuffs. The great interest in these polymers at present is due to their ability to behave either as semiconductors or as metals, depending on the degree and type of dopin
