Anionic surfactant dihexadecyl phosphate (DHP) with two hydrocarbon chains can be self-assembled into a double-layer structure with tail-to-tail configuration and negatively charged head groups toward outside in its aqueous dispersion. Due to this unique biomembrane-like structure, the “charge ...

Hydroxyapatite serves as a bioactive material for biomedical purposes, because it shares similarities with the inorganic part of the bone. However, how this material deposits on metallic surfaces using biomimetic matrices remains unclear. In this study, we deposited dihexadecyl phosphate, a phos...

A new architecture for a sensor and a voltammetric procedure were proposed, using a glassy carbon electrode modified with nanodiamonds and dihexadecyl phosphate for determination of codeine (COD) in pharmaceutical and biological fluid samples. Square-wave voltammetry (SWV) was used and the relev...

Sulfites are food additives found in a large variety of food products to help reduce oxidation and browning. A small subset of the population has “allergic-like” symptoms upon consumption of sulfite containing foods. There are several sulfite detection methods available in the literature that ...

The advanced oxidation processes (AOPs) based on oxysulfur radicals (SO3−, SO4− and SO5−) has been receiving growing attention in wastewater treatment. In this study, we report the in situ photoelectrochemical activation of sulfite to produce oxysulfur radicals with MoS2 nanosheets as a wide spe...

A long-standing challenge for hydrogen production via solar water splitting is the efficiency of converting solar energy to hydrogen chemical energy. Thermolysis, photocatalysis and electrolysis are three basic solar water splitting processes that utilize solar thermal, photonic and electrical e...

Butyric acid-producing strain Clostridium tyrobutyricum ATCC25755 produces acetic acid as a byproduct, which lowers butyric acid yield and selectivity. Supplementing glycerol would be a rational approach to enhance a NADH-requiring metabolite butyric acid selectivity by increasing NADH availabil...

The solubilities of succinic acid, glutaric acid and adipic acid in propionic acid + water solvent mixtures at 304.25–354.65 K, and in propionic acid + ε-caprolactone + water solvent mixtures at 297.65–351.25 K were determined by the synthetic method at atmospheric pressure. The experimental ...

Trypanosomatids are protozoan parasites that cause various diseases in human, such as leishmaniasis, Chagas disease and sleeping sickness. The highly syntenic genomes of the trypanosomatid species lead the assumption that they can encode similar proteins, indicating the possibility to design new...

Eleven new steroidal mono- and bis(semicarbazones) 2a–e, 4d and 3a–e have been prepared starting from various 3-oxo-α,β-unsaturated steroids. Mono-semicarbazones 2a–e were further subjected to ethyl chloroacetate in boiling absolute ethanol but, instead of expected intramolecular cycloconde...

In the present study, we investigated the in vitro and in vivo leishmanicidal activity of synthetic compounds, containing a semicarbazone scaffold as a peptide mimetic framework. The leishmanicidal effect against amastigotes of Leishmania amazonensis was also evaluated at concentration of 100 μ...

Aristolochic acid (1), a constituent of Aristolochia species, has been used for medicinal purposes since the Graeco-Roman period. Following the observation that the compound was mutagenic and carcinogenic, it was removed from pharmaceutical products. Consistent with previous reports, we have fou...

This paper expands upon our original work on nitroanthracenes in (Alparone, A., Librando, V., 2012. Spectrochim. Acta A 89, 129–136) on the series of nitrophenanthrene isomers. Geometries, electric properties, IR and Raman spectra of 1-, 2-, 3-, 4- and 9-nitrophenanthrene (1-NP, 2-NP, 3-NP, 4-N...

XRD reveals the single crystal of 9-bromophenanthrene (9-BrP) with an infinite herringbone chain structure constructed by itself based on C–H⋯π hydrogen bond and additional edge-to-edge type π–π interaction between phenanthrenes. While, 9-iodophenanthrene (9-IP) possesses an infinite zigzag...

Consideration is given to the various parameters which affect the yield and selectivity of propanoic acid formation in the hydrocarboxylation of ethene using a rhodium/I− catalyst. The source of rhodium, the solvent, the form of iodide promoter, the composition of the carbon monoxide/ethene mixt...

This paper describes the preparation, characterization and electrochemical study of various iron and lithium iron phosphates. The pristine iron phosphate samples obtained were amorphous materials with various textural properties, in terms of average pore size, pore order and specific surface are...

Cobalt selenite dihydrate (CoSeO3·2H2O) is spin-coated on conductive glass and used as counter electrode (CE) in dye-sensitized solar cells (DSSCs). Owing to CoSeO3·2H2O electrode good electrocatalytic activity, high conductivity and low resistance, the DSSC based on optimal CoSeO3·2H2O CE pr...

The use of lithium bis-catechol borate (LiB(cat)2) as a reductive quencher for the photoredox mediated intermolecular C–H functionalization of various heteroaromatics with bromopyrroloindolines is described. LiB(cat)2 offers a financial benefit over state-of-the-art quenchers currently in use w...

Hybridization of battery-type positive and capacitor-type negative activated carbon (AC) electrodes has been realized in a carbon/carbon electrochemical capacitor by adding potassium iodide (0.5 mol L−1 KI) to aqueous manganese sulfate (2 mol L−1 MnSO4) electrolyte. Raman spectroscopy proved tha...

The liberation of gaseous hydrogen iodide from azeotropic solution with lithium iodide has been experimentally investigated. The optimum extraction efficiency is achieved with the solid dihydrate of the salt, but solutions containing 65 wt% of the salt liberate hydrogen iodide, too. Low reaction...
