Compounds with Polar Metallic Bonding [PDF]
Crystals, 2019 Recently, I witnessed a discussion amongst solid state chemists whether the term polar intermetallic bonding was necessary or dispensable, whether a conceptual discernation of this special class of intermetallic compounds was indicated or spurious [...]

New Trends in Biopolymer-Based Membranes for Pervaporation
Molecules, 2019 Biopolymers are currently the most convenient alternative for replacing chemically synthetized polymers in membrane preparation. To date, several biopolymers have been proposed for such purpose, including the ones derived from animal (e.g., polybutylene ...

Strategies for Supercritical Fluid Extraction of Polar and Ionic Compounds [PDF]
, 1996 The methods used to facilitate the supercritical fluid extraction (SFE) of polar and ionic compounds are based on two general principles, either increasing the polarity of the supercritical fluid (SF) (usually CO2) used as extractant or reducing the ...

Polar compounds dominate in vitro effects of sediment extracts [PDF]
, 2011 Sediment extracts from three polluted sites of the river Elbe basin were fractionated using a novel on-line fractionation procedure. Resulting fractions were screened for mutagenic, aryl hydrocarbon (AhR)-mediated, transthyretin (TTR)-binding and ...

Changes in pumpkin seed oil during heating
Grasas y Aceites, 1995 Purified pumpkin seed oil was heated either continuously or intermittently for 10 hours at 180±5°C, and occurring changes were evaluated. Free fatty acids (FFA), peroxide value (PV), colour, polar compounds and viscosity increased, while iodine value and

A rapid method for determination of polar compounds in used frying fats and oils
Grasas y Aceites, 2007 The determination of polar compounds by adsorption chromatography is the most accepted method for the analysis of used frying fats due to its high precision and accuracy. However, this method is expensive and time consuming.
