In this study, attenuated total reflectance Fourier transform infrared (ATR-FTIR) was used to compare the amount of crystalline nifedipine formed in different formula of poly(ethylene glycol) (PEG)–nifedipine solid dispersions when exposed at various relative humidities (RHs) for 2 h at 40°C....
In the chemical industry, ethylene oxide (EtO) is known as a carcinogenic and mutagenic compound that has been commonly utilized, especially as a sterilant for medical products and as a reaction intermediate in the production of ethylene glycol.

Synthesis and Characterization of Star Poly(ε-caprolactone)-b-Poly(ethylene glycol) and Poly(l-lactide)-b-Poly(ethylene glycol) Copolymers: Evaluation as ... Two types of 32 arm star polymers incorporating amphiphilic block copolymer arms have been synthesized and characterized. The first type, ...
This paper uses 2 poly-ethylene glycol stability, boiling point, high heat to the sublimation of the melting point on sulfur in poly-2, and the role of the solvent in the ice, and cold water showers, a NM sulfur-poly-ethylene glycol aerosols, and then 2 with the stability of calcium ...
A major product is 1-propen-2-ol, the enolic tautomer of acetone, whose IR absorption spectrum, and that of its perdeutero analog, are interpreted with the aid of ab initio computations. The observation of matrix-isolated decomposition products of acetone such as acetyl radicals, ketene, ...
The presence of preadsorbed triblock-copolymers reduces the adsorbed amount and causes an effect on the adsorbed proteins similar to that exerted by ethylene glycol: a different type of beta-sheet structure in IgG and a more ordered alpha-helix structure in BSA are provoked. Copyright 1999 ...
