The formation of nanotubes and nanocoils of molybdenum disulphide

Electrochemical lithiation/delithiation performances of 3D flowerlike MoS2 powders prepared by ionic liquid assisted hydrothermal route

“…However, the as-prepared MoS 2 samples before annealing exhibit only three low and broad diffraction peaks, which attribute to (0 0 2), (1 0 0) and (1 1 0) planes, respectively. It is mainly caused by that the MoS 2 samples prepared by the hydrothermal reaction are mainly amorphous and their crystallinity is very poor as reported in the literature [17]. The amorphous MoS 2 samples can be transformed into the crystal one by their annealing.…”

Synthesis and characterization of gallium colloidal nanoparticles

“…An additional improvement of the CLD technique is the synthesis of useful amounts of nanoparticles and the possibility of scaling up the process [24]. This technique consists of the co-deposition of metallic vapors and organic solvents in a freezing matrix at 77 K. Direct contact between metal atoms and solvent molecules (from gas state) allows a better functionalization of the nanoparticles, obtaining lower size particles, stable colloid dispersions and a narrow particle size distribution [25][26][27][28][29]. The aim of this study was to obtain colloidal Ga nanoparticles by CLD with different solvents (acetone, THF and 2-propanol) as well as to study the synthesis parameters such as: latency time, the amount of metal evaporated moles, the colloid concentration and their effects on particle size and the stability of colloidal dispersions, also was analyzed the Ga-Nps agglomeration tendency, its optical properties and its thermal stability.…”

Anisotropic Vanadium Oxide Nanostructured Host Matrices for Lithium Ion Intercalation

“…This observation [12] may be ascribed to C. O'Dwyer et al the existence of preferential longitudinal orientations of the intrinsically anisotropic nanotubes in the pellets [11], as can be seen in Figure 1.…”
