Immobilized liquid membranes for facilitated transport and gas separation
… in chemical engineering. Gas separation using facilitated transport membranes has been the subject of considerable research for many years. Immobilized liquid membranes (ILMs) are an important class of facilitated transport membranes. Despite their potential to provide superior performance, …

Electrochemical facilitated transport: a study in synthesis, simulation and experimentation
… process will be referred to as electrochemical facilitated transport. The design and synthesis of a new ferrocenophane crown ether for use in this work will be presented. Experiments using this model compound were designed and performed to demonstrate the ability to move an ion across the …

Preparation and properties of plasma polymers containing organometallic (CoTPP) or metal (Be) inclusions
… plasma polymers for potential use as fixed site facilitated transport membranes for separation of oxygen and nitrogen, and (2) Beryllium-containing T2B plasma polymers for potential use as coatings on inertial confinement fusion (ICF) targets that are to be diffusion-filled with deuterium-tritium …

Development and Applications of Opioids Alternatives for Pain Management
… affecting motor nerves. The prodrug utilized facilitated transport by glucose transporters across the perineurium, eliminating the side effects typically caused by capsaicin, such as burning pain, seizures, and respiratory depression. A single injection at the sciatic nerves of rats resulted …

Electrochemically-mediated membrane separations for carbon dioxide capture
… The first design uses quinones for facilitated transport of CO₂ across a planar, supported liquid membrane. A mixture of quinone and dianion adduct is sandwiched between two porous electrodes. An analytical solution for the current-potential equation is derived and then used to …

The Environmental Fate and transport of Trenbolone Acetate Metabolites in Agro-Ecosystems
… reasonably well characterized, their fate and transport in the environment is poorly characterized. Therefore, lab, plot, and field scale experiments were used to quantify the mass of TBA metabolites that could transport from agro-ecosystems to receiving waters. Observed leaching of 17a-TBOH …

The Use of Coal for Ferrous Metallurgy in Roman Britain
… (energy for a given volume), which could have facilitated transport and storage. Technical reasons include its superior working properties over charcoal for blacksmithing, as evidenced by its precocious adoption by smiths in the late medieval period and corroborated by contemporary …

Sorption, degradation and transport of estrogens and estrogen sulphates in agricultural soils
… function of hypothetical exposure concentrations facilitated the comparison of the sorption behaviour of both compounds as influenced by the mediator solution. The results emphasized that using the CaCl₂ matrix might result in false inferences for the sorption behaviour of these compounds in a …

The intestinal absorption of n-3 and n-6 polyunsaturated fatty acids: proposed mechanisms from studies using human Caco-2 cells.
… on the specific parameters that influence the transport characteristics of the Caco-2 cells and the accessibility of the fatty acids to the absorption site. The results presented in the first part of this study, show that only early passage Caco-2 cells cultured for 15 day post-confluence in 5 …
