Synthesis and structural characterization of a binuclear iridium complex with bridging, bidentate N-heterocyclic carbene coordination of 2, 2 ':6 ', 2''-terpyridine
(Royal Society of Chemistry, 2009)
Thermal activation of terpyridine in the presence of an unsaturated Ir(III) fragment stabilized by a hydrotris(pyrazolyl) borate ligand gives rise to mononuclear complex 2 and binuclear 3, in which the polypyridine ...

A biradical oxo-molybdenum complex containing semiquinone and o-aminophenol benzoxazole-based ligands
(Royal Society of Chemistry, 2020)
We report a new mononuclear molybdenum(IV) complex, MoOLBISLSQ, in which LSQ (2,4-di-tert-butyl o-semibenzoquinone ligand) has been prepared from the reaction of the o-iminosemibenzoquinone form of a tridentate non-innocent ...

Phosphane-decorated Platinum Nanoparticles as Efficient Catalysts for H2 Generation from Ammonia Borane and Methanol
(Wiley, 2019)
A series of narrowly dispersed Pt nanoparticles of 1.5-2.2 nm in size stabilized by bulky terphenylphosphane ligands has been synthesized by the organometallic method using [Pt(dba)2] as platinum source. These nanoparticles ...

Quantitative characterization of multicomponent polymers by sample-controlled thermal analysis
(American Chemical Society, 2010)
This paper explores the potential of sample-controlled thermal analysis (SCTA) in order to perform compositional analysis of multicomponent polymeric materials by means of thermogravimetric experiments. In SCTA experiments, ...

Nanoclay nucleation effect in the thermal stabilization of a polymer nanocomposite: A kinetic mechanism change
(American Chemical Society, 2012)
The enhanced thermal stability of polymer-clay nanocomposites over the original polymers is one of their most interesting features, and it has been profusely studied within the last decades. Here, a thorough kinetic analysis ...

Boosting the photocatalytic properties of NaTaO3 by coupling with AgBr
(Springer, 2023)
AgBr/NaTaO3 composites, with diferent molar % of NaTaO3 (Br/NTO(X%)), have been synthesized by simple precipitation methods; bare NaTaO3 was synthesized by hydrothermal procedure, while AgBr was synthesized by a ...

Homochiral imidazolium-based dicarboxylate silver(i) compounds: synthesis, characterisation and antimicrobial properties
(Royal Society of Chemistry, 2022-03)
Complexes [Ag(LR)], 2 (LR = 2,2′-(imidazolium-1,3-diyl)di(2-alkylacetate)), were prepared by treatment of compounds HLR, 1, with Ag2O. They were characterised by analytical, spectroscopic (IR, 1H and 13C NMR and polarimetry) ...

EXAFS study of the Fex/ZrO2 composite nanomaterials obtained by sol-gel synthesis
(International Union of Crystallography, 2001-03-01)
The local Zr and Fe arrangements in the nanocomposite system Fex/ZrO2 (x=0-0.2) obtained by sol-gel method were studied by EXAFS. The phase composition was found to vary significantly on iron loading. For the samples ...

Broad-Scope Amination of Aryl Sulfamates Catalyzed by a Palladium Phosphine Complex
(American Chemical Society, 2023-08-03)
Among phenol-derived electrophiles, aryl sulfamates are attractive substrates since they can be employed as directing groups for C–H functionalization prior to catalysis. However, their use in C–N coupling is limited only ...
