Films and monoliths containing the spin crossover complex [Fe(Htrz)(2)(trz)](BF(4)) (trz = 1,2,4-triazole) as nanoparticles have been obtained. The dispersion and consecutive inclusion of the Fe complex in a silica matrix prepared from tetramethoxysilane or tetraethoxysilane afford monoliths or films with a violet colour at room temperature, which turns white above 380 K. This change of colour ...

Evidence suggests that structural plumage colour can be an honest signal of individual quality, but the mechanisms responsible for the variation in expression of structural coloration within a species have not been identified. We used full-spectrum spectrometry and transmission electron microscopy to investigate the effect of variation in the nanostructure of the spongy layer on expression of s...

Dragon fruit (Hylocereus spp.) is one of the exotic grown across world. Fruit has very attractive colour and mellow mouth melting pulp with black seed embedded in along tremendous nutritive property which attract growers from different part India to cultivate this crop originated Mexico Central & South America. It a long day plant beautiful night blooming flower that nick named as “Noble Woman”...

Crystal violet is a triphenylmethane dye which is commonly used in the clothing industry to dye wool, silk and cotton (Kim et al., 2005).While knowledge of the genes and enzymes involved in the biodegradation of this dye is restricted; the mechanistic pathway of its break down is well understood. Yatome and colleagues (1993) were the first to elucidate the degradation of crystal violet by Nocar...

Three simple methods using visual titrimetric, potentiometric and spectrophotometric techniques are described for the determination of acyclovir in pure form and in pharmaceutical formulations. The methods are based on the neutralisation reaction involving the primary amino group of the drug and acetous perchloric acid in acetic acid medium. In titrimetric methods, the titration is completed wi...

Abstract This work includes fabrication and electrical characterization of M etal/ I nterlayer/ S emiconductor (MIS) structures with methyl violet organic film on p- InP wafer. Metal(Ag)/ Interlayer (methyl =MV)/Semiconductor( p -InP) MIS structure presents a rectifying contact behavior. The values ideality factor ( n ) barrier height (BH) for the Ag/MV/ -InP diode by using current-voltage - V)...

CeO2/ZnO nanocomposites were synthesized by microwave method that is the fast process. One of an eco-friendly solvent, ethylene glycol were used the effect of time and power of irradiation were investigated on morphology and size of nanoparticle. Prepared CeO2/ZnO nanocomposites are characterized with X-ray diffraction (XRD) analysis, Transmission Electron Microscopy (TEM), Fourier Transform In...

In this manuscript, we explore stunning fractals as Julia and Mandelbrot sets of complexvalued cosine functions by establishing the escape radii via a four-step iteration scheme extended with s-convexity. We furnish some illustrations to determine alteration in generated graphical images study consequences underlying parameters on variation dynamics, colour, time generation, shape fractals. The...
