Nature

Tsujimoto Y, Tassel C, Hayashi N, Watanabe T, Kageyama H, Yoshimura K, Takano M, Ceretti M, Ritter C, Paulus W.
PMID: 18075589
Nature. 2007 Dec 13;450(7172):1062-5. doi: 10.1038/nature06382.

Conventional high-temperature reactions limit the control of coordination polyhedra in transition-metal oxides to those obtainable within the bounds of known coordination geometries for a given transition metal. For example, iron atoms are almost exclusively coordinated by three-dimensional polyhedra such...

Talanta. 1976 Jun;23(6):449-54. doi: 10.1016/0039-9140(76)80126-9.

A new sensitive, colorimetric method based on the direct measurement of light-absorption by an ion-exchange resin phase, which has sorbed the sample complex species, has been developed. Determinations ofchromium(VI) with diphenylearbazide, iron(II) with 1,10-phenanthroline, copper with Zincon and cobalt...

Determination of uranium(VI) in seawater by ion-exchanger phase absorptiometry with arsenazo III.

PMID: 18187855
Anal Sci. 2008 Jan;24(1):93-8. doi: 10.2116/analsci.24.93.

Terrestrial carbonate deposits with a banded layer structure can be good tools for the extraction of past environmental information on global and local scales using trace element concentrations and stable isotope ratios. The absolute age dating is most important...

A coupling sensitive solid phase spectrophotometric (SPS) procedure for determination of traces of heavy metals (Me-SPS) and multicomponent analysis by multiple linear regressions (MA), a simple methodology for simultaneous determination of metals in mixtures was inaugurated. The Me-SPS procedure...

Oxidation of chromium(III) by free chlorine in tap water during the chlorination process studied by an improved solid-phase spectrometry.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry

The oxidation of Cr(III) at naturally-occurring concentration levels, i.e., µg dm(-3) or lower levels, by free chlorine during the chlorination process of tap water was studied using an improved solid-phase spectrophotometric method, which can be directly applicable to the...

Pharmacogenetics of human ABC transporter ABCC11: new insights into apocrine gland growth and metabolite secretion.

Frontiers in genetics

Ishikawa T, Toyoda Y, Yoshiura K, Niikawa N.
