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.

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, ...
Surface modification of polypropylene microfiltration membrane via entrapment of an amphiphilic alkyl oligoethyleneglycolether surface properties were evaluated by ATR-FTIR spectroscopy and static water contact angle; filtration performance as well as antifouling property were investigate...

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 ...
Clay-sized particles (under 10 μm diameter) were extracted by Stokes’ law sedimentation, and the total content of clay was determined by weighing. Quantitative analysis of clay minerals required the preparation of three different clay samples: an untreated sample, an ethylene glycol treated sample...
Platinum cubes (9.4 ( 0.6 nm,80%) were synthesized by adding 0.5 mL of 2 × 10 -3 M silvernitrate (AgNO 3 ) solution in ethylene glycol (EG) to refluxingEG followed by stepwise addition of poly(N-vinylpyrrolidone)and hexachloroplatinic acid (H 2 PtCl 6 ‚6H 2 O) solutions in ...
Ionic conductivity of poly(ethylene glycol) (PEG) - ammonium chloride (NH4Cl) based polymer electrolytes can be enhanced by incorporating ceramic filler TiO2 into PEG-NH4Cl matrix. The electrolyte samples were prepared by solution casting technique. FTIR studies indicates that the complex formation betw...
Effect of the constrained environment on the interactions between the surfactant and different polar solvents encapsulated within AOT reverse micelles. Herein, we report a study of the interactions between different nonaqueous polar solvents, namely, ethylene glycol (EG), propylene glycol (PG), glycerol...
