نویسندگان
چکیده
Anionic poly(vinylcaprolactam-co-itaconicacid-co-dimethylitaconate) microgels were synthesized via dispersion polymerization and their responsiveness towards cations, namely Mg2+, Sr2+, Cu2+ Fe3+, was investigated.

NMR spectroscopy of Group 13 metal ions: biologically relevant aspects.
In spite of the fact that Group 13 metal ions (Al(3+), Ga(3+), In(3+) and Tl(+/3+)) show no main biological role, they are NMR-active nuclides which can be used in magnetic resonance spectroscopy of biologically relevant systems. The fact that these metal ions are quadrupolar (with the exception of thallium) means that they are particularly sensitive to ligand type and coordination geometry. Th...
متن کاملNobelium: tracer chemistry of the divalent and trivalent ions.
In the absence of oxidizing or reducing agents the chromatographic and coprecipitation behavior of element 102 is similar to that of the alkaline earth elements. After oxidation with ceric ions, the behavior is that expected of a trivalent actinide. Nobelium is the first actinide for which the +2 oxidation state is the most stable species in aqueous solution.
متن کاملMicrofluidically fabricated pH-responsive anionic amphiphilic microgels for drug release
Amphiphilic microgels of different composition based on the hydrophilic, pH-responsive acrylic acid (AA) and the hydrophobic, non-ionic n-butyl acrylate (BuA) were synthesised using a lab-on-a-chip device. Hydrophobic droplets were generated via a microfluidic platform that contained a protected form of AA, BuA, the hydrophobic crosslinker, ethylene glycol dimethacrylate (EGDMA), and a free rad...
متن کاملReactivity and infrared spectroscopy of gaseous hydrated trivalent metal ions.
Hydrated trivalent rare earth metal ions containing yttrium and all naturally abundant lanthanide metals are formed using electrospray ionization, and the structures and reactivities of these ions containing 17-21 water molecules are probed using blackbody infrared radiative dissociation (BIRD) and infrared action spectroscopy. With the low-energy activation conditions of BIRD, there is an abru...
متن کاملThe inhibition of ferroxidase by trivalent and other metal ions.
The inhibitory effects of trivalent and other metal ions on f erroxidase (ceruloplasmin EC 1.12.3.1.) activity were investigated. All trivalent cations tested inhibited ferroxidase activity but the strongest inhibitors had an ionic radius of 0.81 A or less. The inhibition by Al(III) was found to be mixed competitive and uncompetitive with respect to the substrate, Fe(I1). The uncompetitive feat...
