The unique and visually mesmerizing appearance of pearlescent materials has made them an indispensable ingredient in a diverse array of applications including packaging, ceramics, printing, and cosmetics. In contrast to their natural counterparts, such syn ...
We present the photoelectrochemical properties of dye-sensitized solar cells using natural pigments containing betalains and anthocyanins as sensitizers. The dyes extracted from grape, mulberry, blackberry, red Sicilian orange, Sicilian prickly pear, eggpl ...
Prodigiosin-like pigments or prodiginines (PdGs) are promising drugs owing to their reported antitumor, antibiotic, and immunosuppressive activities. These natural compounds are produced by several bacteria, including Streptomyces coelicolor and Serratia m ...
In this paper, an oil and dye flow visualization technique applied in two different cases of experimental testing is described, namely a single fan in crossflow and the wake of a compressor cascade. In both cases, the mixture of paint was prepared using a ...
Accelerated bleaching and photobleaching of diluted solutions of Methyl Orange and other dyes occur only when Co2+-ions are present in solution mediating oxone (2KHSO(5)center dot KHSO4 center dot K2SO4) decomposition. The bleaching of Methyl Orange, Orang ...
Cement based Eternit plates modified by TiO2/SiO2 surface layers acquired self-cleaning properties. The TiO2/SiO2 coating was transparent indicating that the small TiO2 (rutile) crystals cause no significant scattering. The parameters related to the compos ...
The invention relates to nanoparticles based on a metal, on a metal alloy or on a metal derivative coated with a silica layer, in which the silica is crystalline silica, in particular crystalline silica in the cristobalite form. They may be prepared from n ...
