We report X-ray emission spectra of Fe(III), Fe(II), and Co(II) spin-crossover compounds in their high-spin and low-spin forms. It is shown that all X-ray emission features are sensitive to the spin state. Variations of the Kbeta and the Kalpha emission line shapes, which are in agreement with theory, can be used as quantitative probes of the spin state; it(More)
Recently we assisted a strong renewed interest in the fascinating field of molecular spin crossover complexes by (1) the emergence of nanosized spin crossover materials through direct synthesis of coordination nanoparticles and nanopatterned thin films as well as by (2) the use of novel sophisticated high spatial and temporal resolution experimental(More)
UNLABELLED In Romania, anthropozoonoses, and in this nosological context, human viral neuro-infections with incidental transmission by active vectors with natural foci, may be considered infectious diseases with endemic emergence. Since 1996, the form of manifestation of the epidemiological process by viral meningitis and meningoencephalitis, the(More)
Nanocomposite spin crossover (SCO) materials with gold nanoparticles (NPs) - displaying both electronic bistability and plasmonic properties - were synthesized and plasmon-enhanced photothermal spin state switching was evidenced. Using this effect, we demonstrated a three times reduction of the laser power needed for switching the new SCO@SiO2-gold(More)
Nano-objects and thin films displaying molecular spin-crossover phenomena have recently attracted much attention. However, the investigation of spin crossover at reduced sizes is still a big challenge. Here we demonstrate that surface plasmon polariton waves propagating along the interface between a metal and a dielectric layer can be used to detect the(More)
Single crystals of the {Fe (II)(pyrazine)[Pt(CN) 4]} spin crossover complex were synthesized by a slow diffusion method. The crystals exhibit a thermal spin transition around room temperature (298 K), which is accompanied by a 14 K wide hysteresis loop. X-ray single-crystal analysis confirms that this compound crystallizes in the tetragonal P4/ mmm space(More)
The applications of a new segmentation software, Anatomatic, in the evaluation of volumetric measurements of brain infarctions and the new Medimag 3D software in the evaluation of 3D image representation of infarctions are described. These programs are applied to magnetic resonance imaging. The aim of this study is to evaluate the use of these software(More)
