A platinum electrode coated with a copper (II) aminopropyl complex-cellulose acetate membrane and its use for dissolved oxygen reduction
(Elsevier Science BvAmsterdamHolanda, 2003)
Coaxial cross-diffusion through carbon nantoubes
(American Chemical Society, 2009-12)
We present results from nonequilibrium molecular dynamics experiments describing the relaxation of local concentrations at two reservoirs, initially filled with water (W) and acetonitrile (ACN), as they become connected ...
Method of porous diamond deposition on porous silicon
(Elsevier Science BvAmsterdamHolanda, 2001)
Using the electrochemical impedance spectroscopy to characterize carbon steel in biodiesel medium
(2012-12-01)
Electrochemical impedance spectroscopy measurements using two carbon steel electrodes in soybean biodiesel medium, produced by methylic route, were performed in an electrochemical cell that allows positioning the two ...
The effects of the C-terminal amidation of mastoparans on their biological actions and interactions with membrane-mimetic systems
(Elsevier B.V., 2014-10-01)
Polycationic peptides may present their C-termini in either amidated or acidic form; however, the effects of these conformations on the mechanisms of interaction with the membranes in general were not properly investigated ...
Efficient Removal of Heavy Metals from Aqueous Solutions through Functionalized γ-Graphyne-1 Membranes under External Uniform Electric Fields: Insights from Molecular Dynamics Simulations.
(American Chemical Society, 2021)
Carbon-based nanosheet membranes with functionalized pores have great potential as water treatment membranes. In this study, the separation of Hg(2+) and Cu(2+) as heavy metal ions from aqueous solutions using a functionalized ...
Already used and candidate polymeric membranes for CO2 separation plants
(Elsevier, 2018)
This chapter presents the already in used polymeric membranes and the potential candidates for the CO2 acid gas separation. Mainly, this work describes the characteristics of each membrane arrangement and the differences ...
ABS copolymer-activated carbon mixed matrix membranes for CO 2/CH4 separation
(Elsevier Science, 2004-11-01)
The performance of various novel mixed matrix composite (MMC) membranes for separation of CO2 from CH4 was investigated as a function of carbon loading. Acrylonitrile-butadiene-styrene (ABS) copolymer was used as the polymer ...
Removal of heavy metals from water using hybrid membranes of whey protein fibrils and activated carbon
(Universidad de La Sabana, 2021-02-15)
Water contamination with heavy metals such as mercury (Hg) and chromium (Cr), have a massive effect in the ecosystem due to the bioaccumulation and biomagnification that is produced in the organisms and the food chain. ...
Physical and in vitro biological evaluation of a PA 6/MWCNT electrospun composite for biomedical applications
(Sage Publications LtdLondonInglaterra, 2011)
