Herein we detail the synthesis and characterisation of a series of zirconium compounds featuring the bis(amido)silyl ligand [(i)Pr2Si(NDipp)2](2-) (Dipp = 2,6-diisopropylphenyl). The functionalisation of bis(amido)silyl zirconium halide complexes with a variety of nucleophiles, such as LiNMe2, LiBH4 and MeLi, was explored and the resulting products showed a propensity to form anionic zirconate ...

The stabilizing and destabilizing mechanism in the action of acetylacetone on zirconium propoxide precursors is revealed; the nature of heteroleptic intermediates provides an explanation.

A catalyst for the oligomerization of 1-hexene, generated by the activation of a benzimidazolylidene zirconium dibenzyl complex, switches to a polymerization catalyst on addition of a trialkylphosphine.

introduction: since it is not possible to form an adequate micromechanical bond between resin cement and zirconia ceramics using common surface treatment techniques, laser pretreatment has been suggested for zirconia ceramic surfaces. the aim of this study was to evaluate the effect of carbon dioxide (co 2 ) laser treatment on shear bond strength (sbs) of resin cement to zirconia ceramic. metho...

Objective: To develop silver nanoparticles stabilized in the hydroalcoholic extract of Mentha Piperita L. for adjuvant treatment depression. Methodology: In synthesis a solution, 25 mL nitrate (1.0 mmol/L) and 75 sodium borohydride (2.0 were used. These two substances mixed at room temperature under magnetic stirring. Another solution used 100 until boiling was reached 5 citrate (1%) added The ...

Reduction of reconstituted native type collagen fibrils with sodium borohydride produced a firmly cross-linked polymer as determined by solubility, thermal shrinkage and dissolution, and renaturation studies, and by examination of the denatured protein by ultracentrifugation, gel filtration, polyacrylamide electrophoresis, and carboxymethyl cellulose chromatography. Maximum reduction occurred w...
