By a direct-liquid-evaporation chemical vapor deposition (DLE-CVD) method, we deposited smooth lowresistance cobalt (Co) and cobalt nitride (CoxN) thin films with excellent conformality at low temperatures down to 200 1C. In the DLE process, a cobalt amidinate precursor solution, bis(N,N0-diisopropylacetamidinato)cobalt(II) dissolved in tetradecane, was vaporized as it flowed smoothly, without ...

We report spontaneous motion in a fully biocompatible system consisting of pure water droplets in an oil-surfactant medium of squalane and monoolein. Water from the droplet is solubilized by the reverse micellar solution, creating a concentration gradient of swollen reverse micelles around each droplet. The strong advection and weak diffusion conditions allow for the first experimental realizat...

A new approach for predicting a wide range of physical and thermodynamic properties is proposed. It involves calculation of the molecular descriptors of a target compound of unknown properties, followed by regression of this vector of molecular descriptors versus a database of compounds with known descriptors and measured properties. The regression model, obtained for the descriptors of a targe...

A series of new synthetic ligand compounds which chelate divalent cations was examined for the antibacterial activities of the compounds. Only 2 of 14 synthetic chelators, 9-trans-anthryl-1, 4, 8, 11-tetraaza-tetradecane (No. 6) and bis(2-pyridyl)methylamine (No. 13) showed antibacterial activities, whereas none of the diamines, hydrophilic triamines nor tetramines showed antibacterial activiti...

This article studies the catalytic activity of multi-walled carbon nanotubes (MWCNTs) in oxidation reactions aliphatic and polycyclic hydrocarbons is studied. In order to determine activity, MWCNTs catalysts containing 22.8% Fe each were used. Catalyst samples synthesized from propane gas under optimal conditions determined by CVD method. The experiments performed at 5 different temperatures (6...

Early diagnosis of colorectal cancer is crucial to increase the survival rates patients and breath analysis represents a promising non-invasive tool obtain information on cancer-related variations human volatilome. A solid phase microextraction coupled gas chromatography–mass spectrometry method for determination seven selected compounds, representative volatilome secreted by colonic mucosa aff...

In this paper, a novel core-modified porphyrin with meso-aryl substituents and phenanthrene-fused pyrrole rings (N2S2-OR) is synthesized. Scanning tunneling microscopy (STM) has been used to probe its self-assembly behavior on a highly-oriented pyrolytic graphite (HOPG) surface. Our STM results have shown that there is an obvious solvent-dependent self-assembly for the surface-confined target m...

AB3217-A, a novel anti-mite substance, was isolated from the fermentation broth of a streptomycete strain. The strain was isolated from a soil collected at Kita-azumi, Nagano Prefecture, Japan, and identified as Streptomyces platensis AB3217. AB3217-A was purified by Amberlite IR120B, Diaion HP-20 and CM-Sephadex C-25 column chromatographies. The molecular formula was determined as C17H23NO7 by...

Liquid-encapsulated lysozyme microspheres were successfully synthesized using a sonochemical method. The encapsulation of four different liquids, namely, sunflower oil, tetradecane, dodecane and perfluorohexane on the formation, stability and morphology of the lysozyme microspheres was studied. Among the four different liquids used for encapsulation, perfluorohexane-filled microspheres were fou...

In a study of the solubility of crystalline forms of cholesterol in various solvents, the solubilities (per cent by weight) of cholesterol needles and hydrated plates at 38#{176} were, respectively, 4.0 and 3.2% in olive oil; 2.6 and 1.9% in tetradecane; 26.2 and 9% in toluene; and 21.0 and 7% in cyclohexane. When these solvents are in equilibrium with an aqueous phase, needles are converted to...
