In this study, BaZr1-xCoxO3 nanoparticles, x = 0.00, 0.04, 0.06, 0.08, 0.10 and 0.20, are synthesized through co-precipitation method. Therefore, structural, optical and magnetic properties have been investigated. The cubic perovskite structure is confirmed by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopic measurements. The average crystallite size and micro strain ...

In a recent article the principles of and the recommended practices for rescaling scalp-recorded electrophysiological data were submitted to a comprehensive review [Urbach, T.P., Kutas, M., 2002. The intractability of scaling scalp distributions to infer neuroelectric sources. Psychophysiology 39, 791-808]. The authors argued, on both conceptual and pragmatic grounds, that the practice of resca...

In this review the effects of clustering associated with the sp and sp phases of amorphous carbon thin films are examined. We highlight that many of the optical and electronic properties of these films can be explained by consideration of disorder in the sp phase. Within the context of topological and structural disorder, we explain the variation of the visible Raman line width, Raman shift, Ta...

The quantification of disorder and the effects of clustering in the sp phase of amorphous carbon thin films are discussed. The sp phase is described in terms of disordered nanometer-sized conductive sp clusters embedded in a less conductive sp matrix. Quantification of the clustering of the sp phase is estimated from optical as well as from electron and nuclear magnetic resonance methods. Unlik...

lipoid proteinosis (lp) is a rare autosomal recessive disease characterized by the deposition of an amorphous hyaline material in the skin, mucosa and viscera. the classic manifestation is onset in infancy with a hoarse cry due to laryngeal infiltration. skin and mucous changes develope, and the disease follows a slowly progressive course. in this case report, a 49 year-old man presented with a...
