Human serum incubated with 2-amino-2-methyl-1-propanol (860 mmol/liter) and magnesium ion (270 mumol/liter) at pH 10.35 showed greater alkaline phosphatase (EC 3.1.3.1) activity than if an equal amount of magnesium ion was added at the time of measurement. The apparent increase is due in part to a slight lability of serum alkaline phosphatase in 2-amino-2-methyl-1-propanol, which is prevented b...

The nematode Caenorhabditis elegans (C. elegans) adult hermaphrodite has 302 invariant neurons and is suited for cellular and molecular studies on complex behaviors including learning and memory. Here, we have developed protocols for classical conditioning of worms with 1-propanol, as a conditioned stimulus (CS), and hydrochloride (HCl) (pH 4.0), as an unconditioned stimulus (US). Before the co...

Enantioseparation is largely based on the formation of transitional complexes, the solvation species, the stationary phase configurations or the diastereomeric complexes formed by analytes and the chiral stationary phase. Temperature and the chemical nature and composition of the eluent play significant roles during that process. In this study; unique temperature-induced behaviors were observed...

Results show that wines could In general, Loureiro, Trajadura and Ped compounds; however, Loureiro wines w whereas Trajadura wines possessed a thio)-1-butanol. Alvarinho and Avesso w 1-propanol, 3-(ethylthio)-1-propanol an tetrahydrothiophen-3-one, cisand tran wines. Azal Branco wines were low in 3contents in S...

Vapor-liquid equilibrium and density measurements have been performed on 1.00-5.89 m tetrabutylammonium bromide (TBAB) in mixtures of 2-propanoland water. The VLE experiments were performed using a modified Othmer still a t ambient pressure. The effect of salt on the relative volatility of 2-propanol was evaluated at molalities of 1.00,1.79, and 5.89 over the full range of solvent composition. ...

In this research, the new separation method based on micro solvent cluster extraction and preferential solvation has been described. A proposed separation method using aqueous mixed solvents of organic solvents (acetonitrile, 1-propanol, 2-propanol and 1,1,1,3,3,3-hexafluoro-2-propanol) or ionic liquids and an open tubular capillary has been separated the model compounds (2-naphthol, 4-nitroani...

Liquid monohydroxy alcohols exhibit unusual dynamics related to their hydrogen bonding induced structures. The connection between structure and dynamics is studied for liquid 1-propanol using quasi-elastic neutron scattering, combining time-of-flight and neutron spin-echo techniques, with a focus on the dynamics at length scales corresponding to the main peak and the pre-peak of the structure f...

In this study, three different compositions of ZnO and TiO₂ powders were cold compressed and then heated at 1250 °C for five hours. The samples were ground to powder form. The powders were mixed with 5 wt % of polyvinyl butyral (PVB) as binder and 1.5 wt % carbon black and ethylene-glyco-lmono-butyl-ether as a solvent to form screen-printed pastes. The prepared pastes were screen printed on the...

Fatty acids esters were produced from two Nigerian lauric oils, palm kernel oil and coconut oil, by transesterification of the oils with different alcohols using PS30 lipase as a catalyst. In the conversion of palm kernel oil to alkyl esters (biodiesel), ethanol gave the highest conversion of 72%, t-butanol 62%, 1-butanol 42%, n-propanol 42% and iso-propanol 24%, while only 15% methyl ester was...
