Abstract CotA laccase was successfully expressed from Pichia pastoris . Magnetic reduced graphene oxide (MRGO) nanocomposite synthesized and functionalized with iminodiacetic acid (IDA-NH 2 ), then chelated Cu 2+ for effective immobilization His-tagged laccase. The -chelated MRGO (MRGO-IDA-Cu ) showed 175 mg/g-support adsorption capacity. of MRGO-IDA-Cu nano-hybrid composite confirmed by Raman ...

Potassium ion sensors are important for the study of concentration profiles in tissues. The synthesis a cryptand suited potassium ions and crystal structure it with chelated sodium presented.

To develop the structural and functional modeling chemistry of [NiFe]-H2ases, we have carried out a study regarding synthesis, characterization reactivity new series [NiFe]-H2ase model complexes. Thus, treatment diphosphine dppb-chelated Ni complex (dppb)NiCl2 (dppb = 1,2-(Ph2P)2C6H4) with (dppv)Fe(CO)2(pdt) (dppv 1,2-(Ph2P)2C2H2, pdt 1,3-propanedithiolate) NaBF4 gave dicarbonyl [(dppb)Ni(pdt)F...

Different conformers can be stabilized for flexible porphyrins upon electron doping. The metastable flat conformer relaxes to the energetically favored distorted form, inducing spin switching in chelated nickel ion.

UNLABELLED Many forms of organocomplexed gadolinium (Gd) contrast agents have recently been linked to a debilitating and a potentially fatal skin disease called nephrogenic systemic fibrosis (NSF) in patients with renal failure. Free Gd released from these complexes via transmetallation is believed to be the most important trigger for NSF. In this work, nanostructure silica materials that have ...

Sorbitol has the effect of promoting nutrient absorption, so it potential to produce excellent fertilizers. In this study, sorbitol calcium chelate was synthesized using as chelating agent. The effects on peanut were investigated, with goal yield and improving utilization fertilizer. Field experiments carried out in Jimo, Shandong Province, China. Four concentrations (0.4, 0.8, 1.6 2.4 g L-1) t...
