NOVELTY - The component partially or wholly comprises pigmented ceramic. The pigment comprises nanoparticles of metal of group IB in periodic table, alkaline metals or their alloy, coated with a layer of silica such as crystalline silica. The crystalline s ...
Large-scale, ultralong ZnO nanowire and nanobelt arrays with honeycomb-like micropatterns have been fabricated by hydrothermal oxidation of zinc foil in aqueous alkaline (NH4)2S2O8 solutions. ...
Highly selective separation of yttrium (and lanthanides) is of interest for the design of radiopharmaceuticals, and an efficient method based on the ion-imprinting concept is proposed here. The synthesis and structural, thermodynamic and photophysical char ...
A facile pathway to [RuCl2(η6-benzocrownether)]2 complexes is described and crystal structures of the complexes [RuCl2(η6-benzo-15-crown-5)]2 and [RuCl2(η6- ...
This work presents the preliminary results on application of mineral sacrificial layer that is prepared to structure LTCC (low temperature co-fired ceramic). The proposed method suggests utilization of a sacrificial paste, which remains "permanent" during ...
The use of organometallic reagents for functionalization of arenes and heterocycles has recently been renewed by our group. The use of bulky trialkylsilyl groups allows one to shield an acidic position by steric hindrance and the introduction of a chlorine ...
Arene hydrogenation by homogeneous catalysts is a highly controversial area of research, with many of the mononuclear complexes shown to catalyse the reaction, being found to be pre-catalysts to nanoparticles, on closer examination. The solvent properties ...
Phytoextraction is an environmentally sound method for cleaning up sites that are contaminated with toxic heavy metals. However, the method has been questioned because it produces a biomass-rich secondary waste containing the extracted metals. Therefore, f ...
Several washing agents ( EDTA, CDTA, NTA, 8 HQS, Ti-EDTA- citrate, Ca2+, and H+) were tested for their ability to extract adsorbed metal from biological surfaces to distinguish between internalized and total cellular metal (Pb, Ni, Cd, Zn, and Cu) for a gr ...
The aim of this thesis was to synthesise and control a nanostructured composite of copper/cobalt. Both the copper and cobalt oxalate exhibit a nanostructure. Attempts to produce nanocomposite particles in the size range of 10-70 nm were made via an oxalate ...
