Preparation Conditions

Ga2O3 nanowires were prepared by vapor-solid process in atmosphere, using commercial Ga ingot and Ga2O3 powder or Al2O3 powder as the starting materials. The influence of preparation conditions such as temperature and starting material on the products was studied. The composition and morphology of the products were characterized by XRD, SEM/EDX, TEM, and HRTEM. The formation mechanism of the products was proposed.

Synthesis And Characterization

La2(MoO4)3 microcrystals with rodlike morphology have been successfully grown through hydrothermal microemulsion process at 180°C, pH =9 and 12 h. Quaternary microemulsion is composed of CTAB/water/hexane/n-pentanol. The obtained sample is characterized by means of XRD, FESEM, TEM. Formation mechanism is preliminarily discussed.

An new method is described for fabricating BiFeO3@PVDF composites using sultraviolet light to motivate the surface electronic of BFO conduct reduction system. The synthesis scheme consists of: (a) preparation of BiFeO3 nano particles using Hydrothermal synthesis method. (b) oxidation of the PVDF powders in the effect of the mixed gas (ozone and dioxygen) and sultraviolet light. (c) redox reaction of the oxidated PVDF and BiFeO3 nano particles in the effect of sultraviolet light. The synthesized BiFeO3@PVDF composites show that this method could increase the compatibility between PVDF and BiFeO3 nano particles. Moreover, a formation mechanism for the composite is proposed.

Solvothermal Route

Porous cobalt (Co) microspheres were successfully synthesized via a facile surfactant-free solvothermal route. These microspheres have an average diameter of about 2 µm, assembled by many primary Co nanosheets. A possible formation mechanism of porous Co microspheres is discussed. The magnetic hysteresis loop shows a ferromagnetic feature of porous Co microspheres and the saturation magnetization (Ms) and coercivity (Hc) are 115.3 J/T·kg and 6.883 kA/m, respectively.

ABSTRACTThe first steps in the synthesis of nanostructures are followed through UV-Vis and correlated with photoluminescence and images taken by SEM and TEM. Colloids permit the control in the atomic arrangement and the formation of nanostructures used to build cluster of materials. The size of the cluster in the colloid is around 5 nm. After the formation of the colloid a hydrothermal growth and microwave heating allows the formation of an ensemble of nano-sheet. This work is aim in the direction to controls the synthesis and the properties of materials with potential applications as active optical materials.

A simple and cost effective method was reported for the synthesis of β-SiC nanoparticles with differernt morphologies using Taixi coal as carbon source and Fe (NO3)3·9H2O, Co (NO3)2·6H2O and NiCO3·2Ni (OH)2·4H2O as additives, respectively. The structures and morphologies were characterized by XRD, FTIR, BET and SEM. The results show that SiC nanoparticles with lamellar structures were successfully synthesized at 1450 °C with NiCO3·2Ni (OH)2·4H2O as an additive which are very scarce to our knowledge. whats more, the formation mechanism of lamellar structures SiC nanoparticles were also discussed.
