Hydrothermal synthesis of uniform porous carbon nanospheres and their gas storage capacity

Lee M.K., Nam S.W., Han J.S., Kang S., Seoul National University, KR

Highly porous nano carbon materials have been widely developed due to their advanced physical characteristics such as morphology, light weight, but more interestingly the possibility of designing the level of porosity as well as the [...]

Hydrothermal Synthesis of Silver Nanowires and Application as Transparent Conductive Materials

George A.L., McGough P.T., Lunn J.D., Wang W., Kuo T.-C., Todd C.C., Goss J.M., Collins R.M., Malek A., Calverley E.M., The Dow Chemical Company, US

A scalable hydrothermal synthesis for silver nanowires has been developed. The new synthetic route is expected to be compatible with industrially available reactor systems and offer environmental and safety advantages due to use of aqueous [...]

Green and Continuous Hydrothermal Synthesis of Nanophosphors for Biomedical Applications

Gruar R., Kellici S., Tighe C., Darr J., UCL, UK

The luminescent properties of Y2O3:Eu have attracted considerable research interest due to the emission and chemical stability of the oxide phosphor. Subsequently, we evaluated the calcination of YOOH:Eu (4% dopant) synthesised directly in a continuous [...]

A facile low-temperature route for preparing monodisperse Mn3O4 nanopolyhedrons from amorphous MnO2 nanoparticles

Ma J., Zhang S., Liu W., Zhao Y., University of Shanghai for Sci& Tech., CN

In the paper, we firstly show a facile hydrothermal route for synthesizing monodisperse Mn3O4 nanopolyhedrons directly used new-made amorphous MnO2 nanoparticle with its mother solution as precursors. The hydrothermal process was performed at 160 ºC [...]

Hydrothermal synthesis and Photoluminescent characterization of nanocrystalline BaZrO3

Diaz-Torres L.A., Salas P., Castaño V.M., Oliva J., De la Rosa E., Centro de Investigaciones en Optica A C, MX

Uniform well faceted sub-microcrystalline BaZrO3 particles have been obtained by a facile hydrothermal reaction. It is found that both morphology and photoluminescence properties depend on reaction time, complexation surfactant, solvent water to ethanol ratio, as [...]

The use of PEO-PPO-PEO block copolymers in the synthesis of nano ZnO via the hydrothermal method

Young M., Bao X., Loughborough University, UK

This investigation studied the effects of different molecular weight of the blocks in the PEO-PPO-PEO block copolymers, the different starting zinc compounds and different hydrothermal parameters on the particle size and morphology of ZnO. The [...]

Direct hydrothermal synthesis of LiMn2O4 spinel and lithium ion selective adsorption

Zhang Q-H, Sun S-Y, Li S-P, Yin X-S, Yu J-G, East China University of Science and Technology, CN

Spinel LiMn2O4, in which the [Mn2O4] framework provides a three-dimensional interstitial space for Li+ transportation, shows excellent Li+ insertion and extrusion property from the Mn-O lattice. The lithium ion-sieve effect strongly depends on the crystal [...]

Morphological, Crystalline and Photo-luminescent Property of Zinc Oxide Nanorod Array Controlled by Zinc Oxide Sol-gel Thin Film

Huang J-S, Lin C-F., National Taiwan University, TW

Our work provides a systematic study of controllable morphology, crystallinity and photoluminescence (PL) of ZnO nanorod array. Our investigation demonstrates that the pre-treatment conditions of the ZnO sol-gel thin-film have strong influences on the morphology, [...]

Characterization of Nanocrystalline PZT Synthesized via a Hydrothermal Method

Harada S., Dunn S., Cranfield University, UK

Nanoscale lead zirconate titanate (PZT) has the potential to become a key component in a myriad of emerging future applications. A sound knowledge of the underlying physical and chemical processes involved in the formation and [...]
