Conditions for derivatization of C5C20 isoprenoid alcohols and the reversedphase liquid chromatographic properties of the corresponding benzoate and naphthoate esters are described. A non-linear response of log k' to changes in the composition of the mobile phase was observed on a RAdial-...

Oleandrin, the major biologically active constituent of shrub Nerium oleander preparations of which have been used in traditional Mediterranean and Asian medicine, attracts a great deal of attention due to its pronounced anticancer activity. The synthesis of oleandrigenin model, 16β-hydroxy-3β...

An efficient and highly selective synthesis of bicyclic-α-keto aziridines from 2-bromo-2-cyclopentenone and aliphatic primary amines mediated by phase transfer catalysts (PTCs) in water at room temperature is demonstrated. Bicyclic-α-keto-aziridines are highly strained and reactive compounds t...

In this paper, we will report a combined experimental and theoretical investigation of the molecular structure and spectroscopic parameteres (FT-IR, FT-Raman, 1H NMR, 13C NMR) of 1-(4-chlorophenyl)-3-(4-nitrophenyl)triazene, CNT. The optimized geometry, harmonic vibrational frequencies, infrared...

Solid complexes of lanthanide picrates with a new podand-type ligand, 2,2′-[(1,2-naphthalene)bis(oxy)]bis[N-(phenylmethyl)]acetamide (L) have been prepared and characterized by elemental analysis, conductivity measurements, IR and electronic spectroscopies. The crystal and molecular structures ...

Multiple hydrogen bonds have been widely used to form a supramolecular network and endow materials with enhanced mechanical strength, good elasticity, and/or self-healing properties. In this study, 2-ureido-4[1H]-pyrimidone (UPy) compounds were synthesized and chemically grafted onto the side ch...

The reaction of trifluoromethylated ynamine with various halogenating agents was investigated. N,N-dialkyl(3,3,3-trifluoro-1-propynyl)amines (1) smoothly reacted with bromine to give, after treatment with sodium hydrogen carbonate, N,N-dialkyl-2-bromo-3,3,3-trifluoropropanamide (3-Br) in good yi...

A series of 4-dialkylamino-2-butynyl-succinimide and -hydantoin derivatives were designed containing pharmacophoric elements for dual acting anticonvulsant and antimuscarinic activity. Potent anticonvulsant agents were identified with an extremely rapid onset of protective activity. Succinimides...

Acrylate and methacrylate (acrylic acid type) are compounds with weak polarity which show a non-ideal behaviour. Phase behaviour of these systems play a significant role as organic solvents in industrial processes. High pressure phase behaviour data were reported for binary mixture of propargyl ...

Glycine and structurally related amino acids with activities at chloride channel receptors in the central nervous system also have robust protective effects against cell injury by ATP depletion. The glycine receptor antagonist strychnine shares this protective activity. An essential step toward ...

Strontium iodide doped with europium (SrI2:Eu2+) is a new scintillator being developed for use in high-energy astrophysical detectors with excellent energy resolution. Nonproportionality is the primary limiting factor to improving its energy resolution, although the physics of nonproportionality...

The molten salt of Strontium Iodide (SrI2) and Europium Iodide (EuI2) was filtered by specially designed dual chamber quartz ampoule using micro frit filter. Eu2+ doped SrI2 single crystal was grown by modified transparent vertical Bridgman technique. Photoluminescence (PL) excitation and emissi...

Europium-doped strontium iodide (SrI2(Eu)) is a promising material for the scintillation crystals in a Compton imaging system, which requires an excellent energy resolution, as an alternative to NaI(Tl) crystals. Rectangular SrI2(Eu) crystals with dimensions of 10×10×10mm3 are fabricated, aimi...

This work characterizes a commercially available europium-doped strontium iodide detector recently developed by Radiation Monitoring Devices (RMD). The detector has been chosen for a space-based mission scheduled to launch in early 2017. The primary goal of this work was to characterize the dete...

High optical quality undoped strontium iodide crystal grown by using the Bridgman method was characterized. Crystal growth process was described and growth technical parameters were discussed. Impurity analysis of raw materials and as-grown crystal boule indicates that it is feasible to pre-puri...

Thermal characteristics such as thermal conductivity, permeability, and sorption kinetics, which determines the overall sorbent performance, play as the critical roles in the sorption refrigeration system. In this paper, composite strontium chloride (SrCl2) developed with a host matrix of Expand...

It is known that the salts of fatty acids (soaps) may have layered structures with inter-layer spacings of 50 Å or more. If the metal ion is from the transition or rare-earth groups, there is the possibility of forming interesting quasi two-dimensional magnetic materials. This is verified by mea...

The magnetic properties of manganese stearate, a highly two-dimensional magnetic material, are found to be changed considerably when it is synthesized by a new procedure. Whereas earlier samples behaved like weak-ferromagnets with ordering temperatures about 5 K, the new material is an antiferro...

Metal-organic multilayers of manganese stearate prepared by Langmuir–Blodgett (LB) technique on hydrophobic Si substrate were studied by grazing incidence X-ray scattering techniques. Grazing incidence X-ray diffraction measurements show distorted hexagonal in-plane structure of the molecules. ...

Marine corrosion and biofouling on metallic materials are sticky problems. Herein, we prepared hierarchical structured superhydrophobic (SHPB) surfaces via a versatile one step electrodeposition approach. The synthetic SHPB surface was employed as an efficient barrier against corrosion and Chlor...
