Broom-like and flower-like heterostructures of silver molybdate through pH controlled self assembly
(2012)
Silver molybdate microrods are selfassembled into micron sized, broom-like and flowerlike structures. Our investigations indicate that through a simple hydrothermal process, large scale production of such structure is ...
Synthesis and structural and spectroscopic characterization of a complex between Co(II) and imino-bis(methylphosphonic acid): Gaining insight into biologically relevant metal-ion phosphonate interactions or looking at a new Co(II)-organophosphonate material?
(2002)
Cobalt is an essential metal ion involved in key biomolecules, regulating processes in human physiology. As a metal ion, Co(II) assumes forms, which are dictated by the nature of organic binders in biological fluids, and ...
Fabrication of nanocrystalline Mg 2Si via ball milling process: Structural studies
(2012)
In this work, nanocrystalline Mg 2Si material was fabricated via wet ball milling process using n-hexane as process control agent. Milling parameters, with emphasis on milling time and ball size, and conditions were studied ...
Synthesis, characterization, and study of octanuclear iron-oxo clusters containing a redox-active Fe4O4-cubane core
(2008)
A one-pot synthetic procedure yields the octanuclear FeIII complexes Fe8(μ4-O)4(μ-pz*) 12X4, where X = Cl and pz* = pyrazolate anion (pz = C3H3N2-) (1), 4-Cl-pz (2), and 4-Me-pz (3) or X = Br and pz* = pz (4). The crystal ...
CsMBi3Te6 and CsM2Bi3Te7 (M = Pb, Sn): New thermoelectric compounds with low-dimensional structures
(2002)
The new materials CsPbBi3Te6 nad CsPb2Bi3Te7 were discovered through reactions of CsBi4Te6 with PbTe, whereas the isostructural materials CsSnBi3Te6 and CsSn2Bi3Te7 were discovered through corresponding reactions with SnTe. ...
Correlations of synthetic, spectroscopic, structural, and speciation studies in the biologically relevant Cobalt(II) - Citrate system: The tale of the first aqueous dinuclear Cobalt(II) - Citrate complex
(2003)
Synthetic efforts targeting soluble species of Co(II) with the low molecular mass physiological ligand citric acid led to the isolation of the first dinuclear complex [Co2(C6H5O7)2 (H2O)4]2-, at pH ∼5, in the form of its ...
Unconventional magnetism in all-carbon nanofoam
(2004)
We report production of nanostructured magnetic carbon foam by a high-repetition-rate, high-power laser ablation of glassy carbon in Ar atmosphere. A combination of characterization techniques revealed that the system ...
Synthesis, structure, magnetic properties and aqueous solution characterization of p-hydroquinone and phenol iminodiacetate copper(ii) complexes
(2008)
The reaction of Cu2+ acetate monohydrate with 2-[N,N′-bis(carboxymethyl)aminomethyl]-4-carboxyphenol (H 4cacp), 2-[N,N-bis(carboxymethyl)aminomethyl]hydroquinone (H 4cah) and the dinucleating 2,5-bis[N,N-bis(carboxymethy ...
Vanadium(IV) - Citrate complex interconversions in aqueous solutions. A pH-dependent synthetic, structural, spectroscopic, and magnetic study
(2001)
Citrate is abundantly encountered in biological fluids as a natural metal ion chelator. Vanadium participates in biological processes as a catalyst in the active sites of metalloenzymes, as a metabolic regulator, as a ...
Near critical behavior in the two-dimensional spin-gap system SrCu2(BO3)2
(2002)
The temperature dependence of the powdered X-band ESR spectra has been measured in a two-dimensional spin-gap system SrCu2(BO3)2 in the temperature range between 5 and 300 K. The spectra are composed of two overlapping ...
