For the investigation of spin crossover (SCO) complexes by x-ray absorption spectroscopy (XAS) measurements in tender to hard regime, a transmission heating cell has been developed. Some SCO show transition at certain temperatures above room temperature (RT). To measure reliable hysteresis curve, high stability (preferably <0.5 °C) as well minimal overheating setpoint (<1 achieved. The is designed for use our von Hámos XAS laboratory spectrometer. complex [Fe(bzimpy)2](ClO4)2 ·...
While X-ray diffraction (XRD) is a commonly used method for quantification analysis using Rietveld refinement and quantitative Mössbauer spectroscopy sporadically primarily iron speciation, laboratory Absorption Fine Structure Spectroscopy (lab-XAFS) rarely applied the determination of sample compositions. With recent developments laboratory-based XAFS spectrometers, this becomes more interesting many applications as well quantification. The goal study to compare lab-XAFS via Linear...
Cochlear and deep brain implants are prominent examples for neuronal prostheses with clinical relevance. Current research focuses on the improvement of long-term functionality size reduction neural interface electrodes. A promising approach is application carbon nanotubes (CNTs), either as pure electrodes but especially coating material The interaction CNTs cells has shown results in various studies, these appear to depend specific type neurons well kind nanotubes. To evaluate a potential...
This paper presents the application of laboratory X-ray Absorption Fine Structure Spectroscopy (XAFS) in field iron coordination chemistry, especially for compounds with larger organic ligands and usually low contents metal.
Many archaeological gold products of the Urals and North Black Sea region contain microinclusions platinum group minerals (PGMs). The trace element composition these was studied using LA–ICP–MS to reveal their microgeochemical features, differences in PGM‐bearing PGM‐free products, source gold. Owing presence ruthenium, osmium iridium, from Filippovka I grave field Phanagoria site are enriched Os, Ru, Ir Rh. Among elements (PGEs), Pt exhibits highest contents products. characterized by...
