A new NIR fluorescent sensor based on an amine-substituted heptamethine cyanine dye displayed a highly selective fluorescence enhancement with cyanide in aqueous solutions, and was applied for the imaging of anthropogenic and biogenic cyanide.

Alkyl aminium sulfates (AASs) can affect the physicochemical properties of atmospheric aerosols such as hygroscopicity. Previous laboratory experiments have shown that the water content in AAS bulk solutions is higher than in aqueous ammonium sulfate solution in the range of 60-95% relative humidity (RH). Furthermore, amine was found to evaporate from the solution during the preparation of AASs...

When Escherichia coli was grown in a synthetic medium containing salts, amino acids, and glucose in the presence of bacteriostatic concentrations of sulfonamides, an increase in total diasotizable amine was noted (1). This has nolv been found to be due to the production of a new heterocyclic amine, the nature of mhich may ultimately throIv light on the mechanism of sulfonamide bacteriost,asis. ...

Carbon dioxide (CO2) is one of the corrosive element which exists in oil and gas industries. To prevent CO2 corrosion on carbon steel pipelines, amine-base solvent caustic solutions are commonly applied. Accordingly, effectiveness amine base to reduce risk becomes key parameters determining service lifetime pipelines made steel. In this research, rate A106 Gr B combined with saturated solution ...

A new method based on combined atomic force microscopy (AFM) and fluorescence microscopy observations, is proposed to visualize the insertion of glycosylphosphatidyl inositol (GPI) anchored alkaline phosphatase from buffer solutions into supported phospholipid bilayers. The technique involves the use of 27 nm diameter fluorescent latex beads covalently coupled to the amine groups of proteins. F...

A total of 1099 data points consisting of alcohol-alcohol, alcohol-alkane, alkane-alkane, alcohol-amine and acid-acid binary solutions were collected from scientific literature to develop an appropriate artificial neural network (ANN) model. Temperature, molecular weight of the pure components, mole fraction of one component and the structural groups of the components were used as input paramet...

Amine precursors such as NH-Boc (5) and NH-formyl (6) protected glycines were grafted by esterification on the hy-droxylated arms of 1-(2-hydroxyethyl)-3-methylimidazolium hexafluorophosphates 4h or tetrafluoroborates 4t. The Boc cleav-age was then realized at room temperature by successively treating acetonitrile solutions of the carbamates 7h or 7t with methanol and acetyl chloride (2 equival...
