In this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing N,N-dimethyl acetamide (DMAc) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 K. The results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. Deviation values of heavy alcohol have more positive and less negative excess...

Following our previous paper, we exammed the effects on the heme synthesis in quail yolk sac cells of polar compounds, other than dimethyl sulfoxide. that induce erythroid cell differentiation in cultured Friend leukemia cells. Dissociated yolk sac cells from quail embryos at the definitive primitive streak stage were cultured in a gyratory shaker in a medium containing dimethyl sulfoxide or ot...

In the title compound, C(6)H(5)IO(3)S·C(4)H(9)NO·H(2)O, N,N-dimethylacetamide and 4-iodobenzenesulfonic acidmolecules are linked by an intramolecular C-H⋯O hydrogen bond. In the crystal structure, inter-molecular O-H⋯O, O-H⋯I and C-H⋯O hydrogen bonds link the mol-ecules.

This article describes the development of a suitable Gel Permeation Chromatography method for cellulose nitrate plasticised with camphor (celluloid) found in cultural heritage. Current sample preparation and dissolution methods, apart from focusing on native, nonderivatised cellulose, require long times, often employ solvents that induce degradation. study aims to develop systematic uses least ...
