In this work the cattle hair waste (CHW), a solid waste that is generated in the tannery, was tested as an alternative new biosorbent of acid dyes, in order to add value to this waste that was discarded and suggesting a life cycle extension for this material from leather processing. Commercially...

While TiO2 has generated great interest in the removal of organic pollutants in recent years, the effect of the surface chemical property of TiO2 on the adsorption performance is unclear. Here, TiO2 samples were prepared in succinic (without hydroxyl group), malic (with one hydroxyl group) and t...

We introduce a novel selective inversion element for chunked homonuclear decoupling that combines isotope selection via BIRD-filtering with band-selective inversion on the X-heteronucleus and allows efficient real-time decoupling of homonuclear and heteronuclear couplings. It is especially suita...

Single crystals of pure and crystal violet dye-doped L-Argininium bis dihydrogen phosphate were grown using slow evaporation technique. The crystalline nature and the structure parameters were confirmed by powder X-ray diffraction technique. Blue and red shifting hydrogen bonds were predicted by...

The present study investigates the use of defatted microalgal biomass – DAB (waste from microalgal biofuel) as an alternative proposal adsorbent of leather dyes. The biomass was characterized by analytical techniques of Zeta Potential, FTIR, SEM, BET and BJH. The sorption experiments were perfo...

The photochemistry of dye is playing a significant role for understanding the mechanism of electron transfer reactions in photoelectrochemical devices such as photogalvanic cells, DSSC, semiconductor photo-catalysis, photoconductors, etc. Oxazines (Brilliant Cresyl Blue and Nile Blue O) and thia...

Iron is an essential element for higher plants, and its acquisition and transportation is one of the greatest limiting factors for plant growth because of its low solubility in normal soil pHs. Higher plants biosynthesize ferric iron [Fe(III)] chelator (FIC), which solubilizes the iron and trans...

Glioblastoma (GBM) has a poor prognosis despite intensive treatment with surgery and chemoradiotherapy. Previous studies using dose-escalated radiotherapy have demonstrated improved survival; however, increased rates of radionecrosis have limited its use. Development of radiosensitizers could im...

A new polyaminocarboxylic bis-(3-hydroxy-4-pyridinone), derivative of DTPA, DTPA(PrHP)2, was synthesized starting from maltol by means of a coupling reaction of a protected 3-hydroxy-4-pyridinone and DTPA bis-anhydride. The DTPA(PrHP)2 acid-base behavior was investigated by UV–Vis spectrophotom...

Raman and infrared spectra of the trimethylphosphine complex of silver iodide, [(CH3)3P·AgI]4, are reported for the first time. Although a complete vibrational assignment could not be made in the absence of polarization data, the presence of the Ag4I4 cluster (Td symmetry) is confirmed and the ...

The 31P NMR spectrum of 1:1 complex of trimethylphosphine and silver(I) iodide in acetonitrile-d3 solution is reported. The 31P NMR spectrum of the complex relative to that of the free ligand in the same solvent shows a downfield chemical shift of 7.1 ppm. In solution, the presence of two trimet...

This study was conducted to determine the interaction of individual corrosion products from biodegradable iron stents with cells from the adjacent tissue. The response of human umbilical venous smooth muscle cells (SMCs) to an excess of ferrous ions was investigated in a cell culture model at th...

In the paper, the processes occurring during low-temperature growth of non-hydrogenated amorphous Si and polycrystalline Si films on multilayer Si3N4/SiO2/c-Si substrates from molecular beams under conditions of ultrahigh vacuum are studied in detail. Diffusion of hydrogen atoms from a dielectri...

Stacking fault energy is a fundamental material parameter in the discussion of plastic deformational mechanisms in metals. In this work, first-principles calculations were performed to investigate the effect of hydrogen atom and hydrogen filled vacancies on the stacking fault energy in fcc Fe, w...

The terahertz spectra (8–128 cm−1) of three structural isomers have been measured using terahertz time-domain spectroscopy at room temperature. Substantial differences among these THz spectra have been found and implied that THz-TDS is an excellent tool to identify isomers. Numerical calculatio...

The terahertz (THz) and mid-infrared (MIR) spectra of benzene-1,2-diol in the solid state have been modeled by density functional theory (DFT). Calculations of the vibrational spectra based on the optimized geometries provided a good fit to the observed spectra, and a more reasonable spectral re...

Acetylcholine (ACh) present inside the brain has ability to alter neuronal activation, influencing transmission of synapse by inducing neurons causing the enhancement in the ability of neuronal networks inside the brain. In result, ACh modifies the response of internal and external environment a...

Modifying the surface properties of 2-D reduced graphene oxide (rGO) nanosheets, transition metal dichalcogenides molybdenum disulfide (MoS2) nanosheets and conducting polymer such as polypyrrole nanotubes (PPyNTs) is worth exploring for the application of electrochemical supercapacitors. Herein...

This work covers some physical investigations on (Co, Ni) codoped molybdenum oxide thin films deposited on glass substrates at 460 °C by the spray pyrolysis technique. The effects of Co and Ni contents on the structural, morphological, optical and magnetic properties of these films were studied...

Chemical characteristics, mineral levels (Ca, Fe, K, Mg, Na, Zn, Cr, Cu, and Mn), fatty acid profile and volatile compounds of typically Brazilian cheeses (Minas Frescal, Minas Padrão, Prato and Coalho, n = 200, equally distributed) were investigated. The cheeses have proven to be a source of Ca...
