Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant that toxic and bio-accumulative. Previously, we used hydrated electrons (eaq–) generated by the UV photolysis of nitrilotriacetic acid (NTA) to initiate photoreductive decomposition PFOS. However, due protonation NTA scavenging effect H+ on eaq–, this process relies highly alkaline conditions. Herein, report an enhanced system b...

In a column experiment with horizontal permeable barriers, the effects of a biodegradable chelator-nitrilotriacetic acid (NTA) on the uptake of heavy metals from municipal solid waste (MSW) compost by Festuca arundinacea and metal leaching were investigated. The use of NTA was effective in increasing Cu, Pb, and Zn uptakes in shoots of two crops of F. arundinacea. In columns with barriers and t...

Lipid analogues carrying three nitrilotriacetic acid (tris-NTA) head groups were developed for the selective targeting of His-tagged proteins into liquid ordered (lo ) or liquid disordered (ld ) lipid phases. Strong partitioning into the lo phase of His-tagged proteins bound to tris-NTA conjugated to saturated alkyl chains (tris-NTA DODA) was achieved, while tris-NTA conjugated to an unsaturate...

In this paper, we report on the functionalization of silicon nanostructured (NanoSi) surface with an organic layer of nitrilotriacetic acid (NTA) and its subsequent use as an affinity surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) interface for histidine-tagged peptide enrichment and mass spectrometry analysis. The NTA terminal groups are immobilized onto the NanoSi s...

We have developed a method based on self-assembly of thiols on Au substrates to immobilize membrane proteins at interfaces. Using water soluble nitrilotriacetic acid (NTA)-terminated oligo(ethylene glycol) thiols, a histidine-tagged G protein-coupled membrane receptor (GPCR) was captured in a defined orientation with little nonspecific binding.

The convergence of food wasted due to spoilage and disposal single use, non-compostable plastic packaging presents a significant economic environmental burden. ongoing market trend reducing additive use in foods generates an opportunity extend shelf life through alternative means. Active technologies which seek ‘clean label’ product at the post-retail level using bioderived polymers thus repres...

Combinations of nitrilotriacetic acid (NTA) derivatives with technetium 99mTc are known as convenient contrasting compounds used in nuclear medicine. Because of low resolution of this method, as well as necessity for using radioactive substances we have suggested new combinations of NTA aromatic derivatives with Gd(III). The aim of the undertaken study was to obtain contrasting compounds showin...

The analytical technique DGT (Diffusive Gradients in Thin-films) is able to gain access a wealth of information by carefully interpreting accumulation data from passive samplers with different configurations (i.e. thicknesses its constituent layers). A set devices were simultaneously deployed solutions Ni and nitrilotriacetic acid (NTA) concentrations measure the availability these solutions. A...

In this research complexation of dioxovanadium(V) with nitrilotriacetic acid (NTA) at differentionic strengths (0.1 to 1.0 mol dm-3) of sodium perchlorate as supporting electrolyte and pH rangeof 1.00-2.50 at 25 °C has been investigated by a combination of potentiometric and UVspectrophotometric measurements. Stability constants of two species, V0211L- and VO2H2L havebeen calculated. Ionic stre...
