In order to reduce the impact of eutrophication caused by agricultural residues (i.e., excess nitrate) in aqueous solution, economic and effective anionic sorbents are required. In this article, we prepared anionic sorbent using wheat straw. Its structural characteristics and adsorption properties for nitrate removal from aqueous solution were investigated. The results indicate that the yield o...

Anionic lipids affect the function of many channels, including connexins, as shown in a recent report in BMC Biology. These effects might follow from direct binding of the anionic lipids to the channels.

The pgsA null Escherichia coli strain, UE54, lacks the major anionic phospholipids phosphatidylglycerol and cardiolipin. Despite these alterations the strain exhibits relatively normal cell division. Analysis of the UE54 phospholipids using negativeion electrospray ionization mass spectrometry resulted in identification of a new anionic phospholipid, N-acylphosphatidylethanolamine. Staining wit...

Rat lungs were inflated and incubated in either anionic or cationic ferritin, and alveolar and capillary basement membranes were examined by electron microscopy. Cationic ferritin bound to heparan sulfate proteoglycans on the external surface of the alveolar basement membrane, whereas cationic ferritin bound to the lamina densa of the capillary basement membranes. Anionic and cationic ferritin ...

The fabrication of electrically conductive hydrogels is challenging as the introduction an filler often changes mechanical hydrogel matrix properties. Here, we present approach for preparation composites with outstanding electrical conductivity at extremely low loadings (0.34 S m–1, 0.16 vol %). Exfoliated graphene and polyacrylamide are microengineered to 3D such that pathways pervade similar ...

Abstract Based on the combined use of polymerisable polyacrylamide, collagen and an aqueous solution Flavin adenine dinucleotide (FAD), we have developed a new technique for fabrication composite phantoms mimicking fluorescence properties human skin. A comparative analysis absorption scattering coefficients, refractive indices, as well spectra with different concentrations FAD measured CCD spec...

Two-phased: Complexation of liposomes to spherical polycationic brushes induces lipid segregation in the liposomal membrane. The greater the initial anionic lipid content in the membrane, the more the electroneutral lipid dilutes the induced anionic clusters.

Anionic quantum dots (QDs) are spontaneously enfolded by coordination networks self-assembled from nucleotide monophosphates and lanthanide ions in water; luminescent core-shell nanoparticles are specifically obtained for anionic QDs, which allows their separation from amine-modified QDs.
