Synthesis, Characterisation and Antifungal Activity of Copper(II)-Functionalised Silicone Polymers and Silicone-Coated Magnetic Nanoparticles
… coating on magnetite nanoparticles (Fe3O4-MNPs). Copper(II) ions were coordinated to the pendant amine groups of all of the polymers. In vitro tests using the fungal pathogen, Candida albicans, revealed that the silicone polymers, their Cu(II) complexes and the Schiff base salicylate derivatives …

π-π conjugated compounds and gold nanostructures for sensor design /
… the modification of electrodes sensitive towards copper (II) ions and surfaces suitable for the formation of separated cells based coatings, whereas gold nanoparticles were used for the formation of substrate possessing bidirectional plasmon resonance suitable for surface enhanced Raman …

Development and characterisation of monolithic silica stationary phases for ion chromatography
… those modified for reversed-phase separations. However, for ionexchange, silica based monolithic columns have received only limited attention. Therefore, the aim of this work was the development and characterisation of novel monolithic stationary phases for the rapid separation o f …

A study of adsorptive bubble separation methods for removal of metal ions from aqueous solution
A study has been made of the removal of the copper (II) ions from aqueous solution by dispersed-air flotation, dissolved-air flotation and liquid-liquid extraction techniques. Precipitation of the copper (II) species has been achieved by complexing with a long-chain a-dioxime, …

Geochemical Aspects of Waste Disposal
… using chemical means applicable to conditions encountered at a waste disposal site. In addition the possibility of finding a catalyst which may promote chemical reactions of phenol to afford less environmentally problematic compounds was investigated. Attention was devoted to catalysts …

Syntheses of selected mono- and di-esters of phosphoric acid and stability constants of their copper (II) complexes
… However, preparative difficulties and side reactions, due mainly to the susceptibility of the 4-nitrophenoxy moiety to nucleophilic displacement reactions, resulted in simplification of the target models to a pair of monoesters (R₃O)PO₃H₂ and a pair of diesters (R₃O)(R₄O)P(O)O⁻Na⁺ where R₃ = …

Synthesis, structure, and magnetic properties of spin-1/2 kagomé antiferromagnets
… show 3-D LRO arising from ferromagnetic interactions between the kagomé planes and interlayer copper(II) ions. Herbertsmithite, in contrast, features 2-D kagomé layers isolated by diamagnetic zinc(II) ions and exhibits no LRO to 50 mK, despite strong nearest-neighbor antiferromagnetic coupling (T …

Metal(ii) schiff base complexes and the insulin-mimetic Studies on the oxovanadium(iv) complexes
… were also successfully coordinated to cobalt(II), nickel(II) and copper(II) ions to form their corresponding complexes. In all thirty-two metal(II) Schiff bases complexes were isolated. These complexes were characterized by elemental analyses, melting point, IR, EPR, cyclic voltammetry, …
