Water determination in composite PEO-based polymer electrolytes by volumetric Karl Fischer titration method.

The determination of water in composite poly(ethylene oxide) (PEO)-based polymer electrolytes by volumetric Karl Fischer (KF) titration is described. The measurements have been carried out on specimens (up to 10 g) of polymer electrolytes (as single components, their mixture and thin film) in a dry-room (relative humidity, RH, <0.2% at 20 degrees C).

Determination of traces of Ni in Li(2)CO(3)/Na(2)CO(3) melts by graphite furnace atomic absorption spectrometry.

A graphite furnace atomic absorption method is described for the determination of traces of Ni in 52mole percent (mol.%) Li(2)CO(3) and 48mol.% Na(2)CO(3) melts after dissolution of the sample in dilute nitric acid.

Sensitive assay for oxygen solubility in molten alkali metal carbonates by indirect flame atomic absorption spectrometric Cr(VI) determination.

A precise and accurate indirect analytical method for the assessment of O(2) solubility in molten (Li(0.62)K(0.38))(2)CO(3) and (Li(0.

Sequential determination of platinum, ruthenium, and molybdenum in carbon-supported Pt, PtRu, and PtMo catalysts by atomic absorption spectrometry.

A simple accurate and precise analytical method for the determination of platinum, ruthenium, and molybdenum in Pt, PtRu, and PtMo nanoparticles catalysts deposited on high-surface area carbon by flame atomic absorption spectrometry (FAAS) and graphite furnace atomic absorption spectrometry (GFAAS) is described. The complete digestion of samples (0.010-0.

Characterization of Sol-Gel-synthesized LiFePO4 by multiple scattering XAFS.

X-ray absorption spectroscopy (XAS) was used to investigate the local structure arrangements of submicrocrystalline lithium iron phosphate and its precursors. The former material, proven to be very promising as active cathode material in lithium metal and lithium-ion batteries, was synthesized through a new procedure that combines a simple sol-gel precipitation with a moderate temperature (e.g.
