abstract = {In the current study, a new approach to the synthesis of highly destacked ReS2 layers embedded in amorphous carbon via the thermal decomposition of a tetraoctylammonium perrhenate precursor, under sulfidizing atmosphere (15% v/v H2S mixture H2S/H-2 gas), is described. X-ray diffraction, scanning electron microscopy, scanning transmission electron microscopy, energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy analysis of the thermolysis product confirm the formation of rhenium disulfide. The synthesized compound is found as single layers with a minor proportion of few-layer arrangements, embedded in amorphous carbon. Xray diffraction, UV-visible diffuse reflectance, and thermogravimetry analysis were made in order to characterize the metal-organic salt precursor, showing that the perrhenate ions are dispersed widely from each other in the matrix of the organic cations, forming an inorganic-organic salt. The special arrangement of these ReS2 layers has a potential use as a heterogeneous catalyst due to the high proportion of edge sites.},

abstract = {This work reports a systematic study of the structural and electrical behavior of three ternary phases of the TaxMo1-xS2 system (x = 0.55, 0.75 and 0.90) and their intercalation compounds resulting from both chemical and electrochemical lithium insertions, as well as from pyridine and poly(ethylene oxide) intercalations. The three ternary phases were prepared by direct reaction of their constituting elements, without any other additive, at 900 degrees C in inert atmosphere. The resulting compounds were characterized by means of X-ray powder diffractometry (XRD), thermogravimetric and differential thermal (TGA/DTA) analyses, energy dispersive X-ray fluorescence (EDX) and field emission-scanning electron microscopy (FE-SEM). The electrical conductivity of the different products was measured in the 1.5-300 K temperature range using the conventional four probe van der Pauw method in the presence of a 9 T magnetic field in order to verify the occurrence of magnetoresistivity phenomena.},
