ZnO materials with a range of different morphologies have been successfully synthesized via a simple double-solvothermal method in the presence of glycine. The morphologies of the products can be controlled from superstructures to microrods by adjusting the amount of water in the EtOH/H2O system. Photoluminescence (PL) studies reveal that the more amount of water was used, the stronger PL relat...

Safe fast-charging lithium-ion batteries (LIBs) have huge potential market size on demand according to their shortened charging time for high-power devices. Zero-strain spinel Li4Ti5O12 is one of ideal candidates for safe high-power batteries owing to its good cycling performance, low cost and safety. However, the inherent insulating characteristic of LTO seriously limits its high-rate capabili...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Reduced graphene oxide-supported Fe₃O₄ (Fe₃O₄/rGO) composites were applied in this study to remove low-concentration mercury from aqueous solutions with the aid of an artificial neural network (ANN) modeling and genetic algorithm (GA) optimization. The Fe₃O₄/rGO composites were prepared by the solvothermal method and characterized by X-ray diffraction (XRD), transmission electron microscopy (TE...

LiMnxFe1-xPO₄/C material has been synthesized through a facile solid-state reaction under the condition of carbon coating, using solvothermal-prepared LiMnPO₄ and LiFePO₄ as precursors and sucrose as a carbon resource. XRD and element distribution analysis reveal completed solid-state reaction of precursors. LiMnxFe1-xPO₄/C composites inherit the morphology of precursors after heat treatment wi...

S/AgI microstructures were produced by solvothermal DMSO-mediated synthesis using two methods of sulfur precipitation: at room temperature (method 1) and water 2). The samples obtained with different percentages AgI: 10, 30 50 %. Microstructures investigated help XRD, Raman spectroscopy SEM/EDS (elemental mapping). XRD confirmed the presence AgI. EDS elemental mapping revealed that composed lar...

CuAlS2  Chalcopyrite  nanocrystalline  are  synthesized  with  facile method.  The  heat  arrested  solvothermal  method  for  synthesize nanocrystalline  were  investigated.  The  time  duration  of  synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters  that we are  studied. The nanoparticles were  synthesized with CuCl, AlCl3 and  thiourea (SC(NH2)2...
