The Raman (3500–50 cm−1) and infrared (4000–200 cm−1) spectra of 3-chloro, 4-chloro and 5-chloro-2-methylphenyl isocyanates have been measured. Ab initio and density functional theory calculations, at the levels of RHF/6-311G* and B3LYP/6-311G*, have been performed: energies, optimized geometr...

Treatment of rats with fentrazamide for 2 years at 3000 ppm (males) and 4000 ppm (females) led to an increased incidence and degree of axonal degeneration in sciatic nerve as well as to effects on red blood cells. The mechanism underlying these effects was investigated in vitro using various cel...

We have recently reported the discovery of pyrrolo[3,2-d]pyrimidine derivatives 1a and 1b as potent triple inhibitors of vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), and Tie-2 kinases. To identify compounds having strong inhibitory activit...

Ternary selenide CuAgSe has potentially outstanding thermoelectric performance owing to its high electron mobility and low thermal conductivity. It has two phases including the room-temperature semimetallic β phase and the high-temperature (above 470 K) semiconductive α phase. However, as the ...

N-chloro-amino acids are readily formed in chlorination water treatment technologies. These reactions are also important in biological systems where HOCl plays an important role in the defense mechanism against invading pathogens. The intermediates and the products formed are of primary concern ...

N-Alkylated-α-amino acids are useful building blocks for the pharmaceutical and fine chemical industries. Enantioselective methods of N-alkylated-α-amino acid synthesis are therefore highly valuable and widely investigated. While there are a variety of chemical methods for their synthesis, the...

Owing to the unique opto-electronic properties, pyrazoline derivatives are considered to be one of the most elegant member in heterocyclic family. In this work we have utilized a pyrazoline dye 3-naphthyl-1-phenyl-5-(4-amino phenyl)-2-pyrazoline (NPAP) for functionalizing graphene oxide (GO) thr...

Olive mills wastewater (OMW) causes a serious environmental problem in the olive oil producing countries. This is due to its high organic matter content (COD), acidic pH values, suspended solids and high content of phytotoxic and antibacterial phenolic compounds. In this study, titanium dioxide ...

Laser ablation of titanium in liquid (LAL) using a fiber laser was studied. Firstly, LAL was carried out in toluene, n-hexane, n-heptane, and acetone as liquid media at the same irradiation conditions. Samples were characterized by different diagnostic techniques X-ray diffraction (XRD), field e...

In order to effectively polish the surface of the titanium alloy workpiece, a novel type of iron nitride magnetic abrasives was designed, prepared and characterized. Theoretically, first-principles were used to analyze the effects of phase compositions of iron nitrogen compounds on the mechanica...

The syntheses and single-crystal X-ray structures of several well-defined hexaphenyltrisiloxanediolates of sodium, titanium, and iron are reported. All these compounds contain eight-membered MSi3O4 rings (M = Na, Ti, Fe). Treatment of 1,1,3,3-tetraphenyldisiloxane-1,3-diol, (HO)SiPh2OSiPh2(OH) (...

The aim of this work was to investigate the treatment of the artificial sweetener saccharin (SAC) in a solar compound parabolic collector pilot plant by means of the photo-Fenton process at pH 2.8. Olive mill wastewater (OMW) was used as iron chelating agent to avoid acidification of water at pH...

Iron is a potential element for developing cheap titanium alloys and a possible stabilizer of the nanostructured state. In this work, solubility, formation of Fe-Fe complexes and grain boundary segregation of Fe are studied in α-titanium using density functional theory. It is found that Fe pref...

The adiabatic temperatures and equilibrium phases in the FeTiO3-αMg-C(B, Si)-kNaCl system (where α = 0.2–15, k = 0–3) were analyzed to predict the formation of fine powders of titanium compounds from natural ilmenite sand. From the parametric study, the critical variables were identified and...
