The decolorization and degradation of Reactive Red 195 (RR 195) is studied using sonoelectrochemical and electrochemical oxidation. Sonoelectrochemical oxidation was found to be more efficient than electrochemical oxidation. The efficiency of decolorization was found to be 91% and 99% in the cas...

Chitosan particles (CP) prepared by coacervation technique were used as bio-sorbent material to remove the azo RR-195 dye; removal percentage (%RM) and adsorption capacity (Q) in batch adsorption experiments under different conditions of bio-sorbent doses, agitation speed and pH medium were dete...

Mesoporous calcined Mg–Al layered double hydroxides with different Mg/Al molar ratios were investigated for their ability to adsorb the commercial dye, C.I. Acid Blue 9, with a view to exploring their suitability as inorganic pigments in Ink Receptive Layer formulation. Uptake capacity was char...

The purpose of this work was to investigate the feasibility of using black tea powder produced through green technology (plant-source material and biotechnology) as multifunctional admixture for the hemihydrate gypsum. The hemihydrate gypsums were mixed with black tea, and the setting times, den...

Keemun, Assam, Darjeeling and Ceylon black teas are honored as the world's four most famous black teas, and their excellent aroma qualities are well received by people around the world. In this study, aroma components in these four types of teas were analyzed by comprehensive two-dimensiona...

Herpesvirus infection was investigated in black bears (Ursus americanus) with neurological signs and brain lesions of nonsuppurative encephalitis of unknown cause. Visible cytopathic effects (CPE) could only be observed on days 3–5 post-infection in HrT-18G cell line inoculated with bear tissue...

Generalized splines are smooth functions belonging piecewisely to spaces which are a natural generalization of algebraic polynomials. GB-splines are a B-spline-like basis for generalized splines, and they are usually defined by means of an integral recurrence relation which makes their evaluatio...

Cu-loaded MgAl hydrotalcite catalysts were synthesized by impregnation method and further used for catalytic wet peroxidation (CWPO) of methyl orange (MO) using hydrogen peroxide as oxidant. The synthesized catalysts have been characterized by XRD, FT-IR, SEM/EDS, TG/DTA, XPS, H2-TPR and BET. Th...

A glassy carbon electrode (GCE) modified with single-walled carbon nanohorns (SWCNH) and zein (ZE), a prolamin type-protein find in maize, for the differential pulse adsorptive cathodic stripping voltammetric determination of fenitrothion (FT) is proposed. The proposed film was characterized by ...

The oxidative degradation of azo dye Reactive Orange 113 aqueous solution by H2O2/Fe2+ and ozone was investigated. The full decolorization is attained during the first minutes of oxidation process by H2O2/Fe2+ and ozone. The complete mineralization of aqueous solutions of Reactive Orange 113 dye...

Six Orange (II) metal complexes of Mn (II), Fe (III), Co (II), Ni (II), Cu (II) and Zn (II) were prepared and characterized by elemental analysis, IR, electronic spectra and magnetic susceptibility. The complexes were of different geometries: Octahedral and Tetrahedral. ESR was studied for coppe...

Aqueous solutions containing the commercial azo dye Reactive Orange 122 (RO122) were ozonated in acid and alkaline conditions. Ozone was electrochemically generated using a laboratory-made electrochemical reactor and applied using semi-batch conditions and a column bubble reactor. A constant ozo...

In this work, we report the preparation of Ni/TiO2 (2 and 5 wt%) catalysts by the impregnation method and calcinations temperature (250, 300 and 400 °C) for the discoloration of dyes reactive orange-122, reactive blue-19 and reactive yellow-145 under artificial and solar light. The characteriza...

In this work, we propose a method that employed a smartphone to capture images obtained from a colorimetric spot test to determine ascorbic acid (AA) in Brazilian Amazon native and exotic fruits. The spot test reaction was based on reduction of Fe(III) by AA and further complexation with 1,10-ph...

The present study aimed evaluate the antibacterial effect of Piper peltatum and Piper marginatum extracts against Alicyclobacillus acidoterrestris using the microdilution method. P. marginatum achieved a minimum inhibitory concentration (MIC)/minimum bactericidal concentration (MBC) of 62.50 μg...

Severe surface roughening during plastic deforming of aluminum alloy parts can produce “orange peel” defects. To analyze “orange peel” of 6063 aluminum alloy tube quantificationally, the tensile tests of trapezoidal specimens were carried out. The tubes with different grain sizes were obtain...

This paper studied the nutritional impact of the use of juice from Strychnos cocculoides (monkey orange) in a maize-based porridge. Monkey orange juice is traditionally used to supplement maize porridge - a staple breakfast cereal especially for vulnerable groups. Monkey orange fruits contain hi...

A label-free fluorescence aptasensor based on tetracycline-binding aptamers and thiazole orange (TO) was established for the selective and sensitive detection of tetracycline. TO is essentially nonfluorescent in aqueous solution, while TO can intercalate into the tetracycline-binding aptamers wi...

Oxidative stress, inflammation status, endothelial dysfunction, and imbalanced lipid metabolism play a major role in cardiovascular disease. Bioactive compounds and moderate alcohol consumption have been associated with decreased cardiovascular risk. This study aimed to evaluate the effect on ca...

Stable carbon isotope ratios (δ13C) for glucose, fructose, disaccharides, trisaccharides, and organic acids in 116 commercial honey samples were measured by LC/IRMS. On the basis of EA/IRMS and LC/IRMS authenticity criteria, 39 of the samples were judged to have been adulterated. The δ13C valu...
