Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) have been identified in a variety of marine organisms from different trophic levels indicating a large spread in the environment. There is much evidence pointing towards natural production as the major source of these compounds in nature. Ho...

The method of the laser ablation-inductively coupled plasma-mass spectrometry has become an effective tool in the analysis of the art and archaeological objects. With a few exceptions, however, it has not been fully established in the provenance analysis of historical paintings yet. Although the...

This paper introduces a holistic approach to the study of Greco-Roman (G-R) lithotherapeutics. These are the minerals or mineral combinations that appear in the medical and scientific literature of the G-R world. It argues that they can best be described not simply in terms of their bulk chemist...

A complete non-invasive characterization by XRF, XRD, near-FTIR and UV–Vis reflectance spectroscopy has been performed on some commercially available violet pigments as well as on pure violet Co-salts also known to be used as pigments. The obtained results show that, after a preliminary element...

A series of neodymium–doped holmium molybdate (Ho1-xNdx)2MoO6 (x = 0-0.8) color pigments with ‘allochroic effect’ were synthesized by a solid-phase reaction method under different conditions (i.e., sintering temperature, sintering time, and neodymium ions (Nd3+) doping amount). The as-synthes...

In this paper, Mg0.5Ti2(PO4)3 with the NASICON-type structure was evaluated for the first time as a possible host structure of Co2+ for obtaining an inorganic pigment with violet color. The powders were synthesized by solution combustion synthesis using glycine (G) and urea (U) as fuels and diff...

The redox chemistry of Alizarin Red S (1,2-dihydroxy-9,10-anthraquinone-3-sulfonate) was studied as function of pH by photometry, potentiometric titration and cyclic voltammetry. Dependent upon solution pH three species of the oxidised form of Alizarin Red S are present. Electrochemical reductio...

In the present study, magnesium oxide (MgO) nanoparticles have been synthesized and their adsorption behavior was tested for the removal of dyes found in textile wastewater. Levafix Fast Red CA (LFR) and Indanthren Blue BC (IB) were chosen as models for reactive and vat dyes respectively. The pr...

The effects of health-related taxes and subsidies on food and beverages have mainly been investigated using models that assume identical price responses among high- and low-consuming households. Diet-related health problems are, however, more likely among households with high intakes of unhealth...

This study aims to develop a robust chemometric approach to make it possible to authenticate European premium organic orange juices. The metabolomic fingerprinting and the volatile profile of commercial orange juices were analyzed by HPLC-HR-MS and HS-SPME-GC-MS. These data were used for authent...

In application of vat dyes the substitution of non-regenerable reducing agents such as Na2S2O4 by cathodically regenerable reducing agents offers great ecological advantages. In a demonstration project a 45 A multi-cathode electrolyser successfully was coupled to a dyeing apparatus for package d...

A number of vat dyes and anthraquinone intermediates (4–8c, 15) have been synthesised and then pigmented using high energy bead milling. These potential pigments have been tested alongside an isoindolinone Pigment Yellow 110 in a thermosetting acrylic/melamine formaldehyde resin paint system. L...

Hydrogen bonding interaction plays a vital role in a variety of chemical and biological process. It is primarily accountable for determining the stability of 3D-structure of folded protein counting antibodies enzymes and various biological molecules. So, here we report an intermolecular H-bondin...

Natural deep eutectic solvents (NADES) based on xylitol, citric acid, and malic acid were synthesized and were then characterized using infrared spectroscopy, thermogravimetry (TG), differential scanning calorimetry (DSC), also density and viscosity were measurements. The deep eutectic solvents ...

The utilization of organic solvents as reaction media for enzymatic reactions provides numerous industrially attractive advantages. However, an adaptation of enzyme towards organic solvent is unpredictable and not fully understood because of limited information on the organic solvent tolerant en...

In this research, ZnO nanocrystals were synthesized by an improved sol–gel method. UV–vis, FTIR and photoluminescence spectra of the ZnO solution synthesized by this route indicated different properties compared to the other preparation methods. It was observed from FTIR that the sol (prepared...

In this manuscript, we reported the effects of solvent vapor annealing on performances of blue polymer light-emitting diodes, where the blue light-emitting poly(dibenzothiophene-S,S-dioxide-co-dioctyl-2,7-fluorene) that comprising dibenzothiophene-S,S-dioxide with molar ratio of 10% was used as ...

Aluminum (III) has high toxic impacts in some human pathologies like renal osteodystrophy, Parkinson's and Alzheimer's disease. So, it is very important to assess and determine the trace concentrations of Aluminum (III) in various water and acid digested food samples. The present work ...

Electropolymerization of brilliant cresyl blue (BCB) in ethaline deep eutectic solvent (DES) has been carried out. Poly(brilliant cresyl blue) (PBCB) films were formed by electrodeposition on carbon nanotube modified glassy carbon electrodes by potential cycling in ethaline (choline chloride + e...

This research describes the spectrophotometric determination of methylene blue (MB) after shaker-assisted liquid-liquid microextraction combined with back-extraction (SALLME-BE). A hydrophobic deep eutectic solvent (DES) was used for extraction of MB from alkaline solutions (0.5 M NaOH). Then, t...
