Although permeation of hydrocarbons such as Benzene, Toluene, Ethybenzene, and Xylene (BTEX) through polyethylene (PE) pipe in potable water applications is rarely occurred. It is important to understand permeation mechanism and characterize the potential health risk. The most common potential hydrocarbon substances are originated from gasoline leaks. Previous research has shown that pipe mater...

OBJECTIVES Normoglycemic Wistar rats' Glycated Hemoglobin Levels (GHL) showed a time-dependent difference between control groups and those exposed to regular inhalation of peroxidizing extracts of turpentine. These extracts were able to optimize the oxygen permeation at the cellular level during and subsequently to a breathing session. The more the rats breathed turpentine peroxidized vapor, th...

The separation of H2O vapor from (hydrogen-rich) gaseous streams is a topic increasing interest in the context CO2 valorisation, where situ water removal increases product yield and catalyst stability. In this work, composite alumina carbon molecular sieve membranes (Al-CMSM) were prepared phenolic resin solutions loaded with hydrophilic boehmite (γ-AlO(OH)) nanosheets (0.4–1.4 wt. % solution) ...

comNode classification within Membrane Residue Curves (M-RCMs) currently hinges on Lyapunov’s Theorem and therefore the computation of mathematically complex eigenvalues. This paper presents an alternative criterion for the classification of nodes within M-RCMs based on the total membrane flux at node compositions. This paper demonstrates that for a system exhibiting simple permeation behaviour...

objective(s):drug delivery through the skin can transfer therapeutic levels of drugs for pharmacological effects. analgesics such as nsaids have gastrointestinal side effects and topical dosage forms of these drugs are mainly preferred, especially for local pains. meloxicam is one of nsaids with no topical form in the market. in this research, we attempted to quantify the skin permeation of a m...

In this paper, a superb water permeable membrane is prepared by treating an alumina hollow fiber supported metal-organic framework (MOF) with hydrophilic ionic liquid (IL). For ternary mixture of H 2 O/CO /H separation, the IL layer separates O and CO from MOF functions as selective for further separation . Furthermore, owing to high hydrophilicity IL, permeation enhanced comparing pristine mem...
