Determination of Extractables from Cranberry Seeds Using Supercritical CO₂
… the extraction yield. The amount and type of SF extractables (pure CO₂) have been compared with Soxhlet extractables (hexane) to evaluate the feasibility of SFE as an alternative extraction method. The extractables obtained via hexane and SF CO₂, which were derivatized and identified by gas …

Seepage of Groundwater into the St. Clair River Near Sarnia, Ontario, Canada
… trihalomethanes, EPA Priority Pollutants (extractables), total organic halides (TOX), chloride, and natural isotopes (oxygen-18, deuterium, and tritium). The average observed seepage rate of l. u x 10-8 m 3/s/m2 suggests higher chan expected hydraulic conductivity or hydraulic gradients in …

Hyphenated fourier transform infrared spectrometry: techniques for separations and analysis
… Following identification of one of the primary extractables, caprolactam, SFE/SFC was used to quantitate the amount of residual starting material in a Nylon copolymer. The second study involves the extractables in polystyrene which is a softer polymer with respect to solubility of components in …

Rheological Considerations for Dual-Extrusion Melt Processing of Dissimilar Polymers in Composite Structures
… water, or after rinsing with water to remove extractables. Extractable content was characterized by the change in dry mass before and after rinsing samples using optical and scanning electron microscopy techniques. The observed excess extractables content of rinsed samples agreed with …

The higher productivity of the bioenergy feedstock Miscanthus x giganteus relative to Panicum virgatum is seen both into the long term and beyond Illinois
… hemicellulose, lignin, acetyl, ash, and extractables at seven locations of varied soil types, with four nitrogen fertilization levels, and pre- and post-senescence sampling on a single genotype of M. x giganteus. Nitrogen fertilization did significantly decrease the proportion of …

Water stability of organic and electrolyte-gated field-effect transistors
Organic bioelectronics is an emerging field that utilizes electronic devices made from a large family of aromatic compounds (conjugated polymers and small molecules) for biological applications. Organic materials seem ideal candidates for bioelectronics due to their softness, biocompatibility, …
