Electronic, optical and energetic properties of antisite BiMO4 defect in the Bi12MO20 (M = Ti, Ge, Si) sillenite crystals have been investigated by means of the first-principles calculations on density functional theory level. The defect is studied in neutral, positive and negative charge state,...

We report on the presence of photovoltaic effect in some Sillenite photorefractive crystals and compare their behavior with that of the well known photovoltaic LiNbO3:Fe crystal. Nonlinear photovoltaic behavior of these Sillenites are also reported here for the first time and explained by the pr...

The ground state structures of the linear L–Ge–As and bent Ge–As–L systems (where L = H, Li, Na, BeH, MgH, BH2, AlH2, CH3, SiH3, NH2, PH2, OH, SH, F, Cl, and Br) have been investigated employing coupled cluster and density functional theory with the correlation consistent basis sets of doubl...

Three commercial anion exchange resins, strongly basic of type 1 (Amberlite IRA-900) and type 2 (Amberlite IRA-910) and weakly basic (Amberlyst A-21) were evaluated for the removal of anionic acid dyes, C.I. Acid Orange 7 and C.I. Acid Orange 10 from aqueous solutions. The pseudo-second order ki...

The interaction of acridine orange (C.I. Basic Orange 14) with bovine serum albumin and the subsequent sonodynamic damage to bovine serum albumin imparted by ultrasonic irradiation were studied. The quenching constant, binding constant and the binding site number were measured using fluorescence...

Different thickness of basic fuchsin dye was deposited on conductive FTO substrate by spin coating technique for the first time. Their structural, morphological, linear/nonlinear optical and optical studies were performed. The structural studies confirm the amorphous nature of the studied dye on...

Five indigenous white rot fungi Pleurotus ostreatus IBL-02, Phanerochaete chrysosporium IBL-03, Coriolus versicolor IBL-04, Ganoderma lucidum IBL-05 and Schizophyllum commune IBL-06 were screened for decolorization of four vat dyes, Cibanon red 2B-MD, Cibanon golden-yellow PK-MD, Cibanon blue GF...

Indigo carmine can be used as a source of blue dye for wool and hair dyeing. The option to use indigo carmine in combination with other natural dyes in a one-bath procedure as a hybrid dyeing concept is of interest both for natural dyeing and for coloration of hair. The present study shows that ...

Recent advancement in dyeing of nanofibers has been accelerated to improve their aesthetic properties, however, achieving good color fastness remains a challenge. Therefore, we attempt to improve the color fastness properties nanofibers. Vat dyes are known for better color fastness and their app...

The design and characterization of indigo dye (C.I. Vat Blue I) have analyzed by several techniques such as XRD, FTIR; optically diffused reflectance based on the Kubelka–Munk model and electrical conductivity/dielectric properties that can use as natural organic semiconductor dyes. The XRD mea...

The accurate monitoring of propionic acid bacteria (PAB) in cheese milk is of high importance since they can provoke undesired propionic acid fermentation during the ripening of unpasteurised milk cheeses. In the present study, we analysed 560 vat milk samples and 40 corresponding Sbrinz cheeses...

The visible light driven pollutant degradation by photocatalysis is one of the most effective and environmentally friendly strategies, which urgently requires the highly efficient catalysis. In this study, the RhB-sensitized MIL-125(Ti) photocatalyst (RhB/MIL-125) was obtained by post-impregnati...

The colour strength of 2% omf dyeings, as well as the extents of both exhaustion and fixation, achieved for three commercial grade reactive dyes on cotton, were promoted by the addition of 50 gl-1 NaCl at each of seven liquor ratios (1:50, 1:20, 1:10, 1:6, 1:3, 1:2 and 1:1.5). The depth of shade...

This paper evaluates the catalytic effectiveness of three iron exchanged ultra-stable Y zeolites (USY) for the degradation of a reactive azo dye, C.I. Reactive Yellow 84 (RY84) using hydrogen peroxide, as an oxidant, under very mild conditions (atmospheric pressure and t=50 °C). The catalysts w...

BackgroundThe aim of this study was to analyze bleaching treatment performed with different products, with or without the use of Violet LED.

Elevated soil lead (Pb) concentrations are a global concern owing to the toxic effects of this heavy metal. Solidification/stabilization (S/S) of soils using reagents like Portland cement (PC) is a common approach for the remediation of Pb contaminated sites. However, it has been reported that u...

A strain HXL-2 from a lab-scale sequence batch reactor (SBR) was identified as Candida rugopelliculosa based on its physiological, biochemical characteristics, and 26S rDNA D1/D2 gene phylogenetic analysis. About 90% of the 50 mg/L Reactive blue 13(RB13) was degraded in 48 h after inoculation wi...

The study of reactive species remains a challenge under ambient conditions owing to their extremely shorter life times. The advent of technique of matrix isolation changed the scenario as the reactive species produced will have a long life time due to the cage effect of matrixes and low temperat...

Dietary fibre yields an additional benefit in terms of stabilisation of food structure or nutritional value, but may alter sensory properties in fibre-enriched foods. This study aims to investigate the impact of pectin-rich orange fibre on rheological, sensory and tribological properties of yogh...

A reasonable, high sensitive and accurate analytical method for the determination of 20 allergenic disperse dyes in foodstuffs was developed and validated. The obtained results showed that an ultra high liquid performance chromatography system - equipped with tandem quadrupole mass spectrometry ...
