Effects of Heat Treatment of ZnS Nanoparticles Prepared by Hydrothermal Synthesis on Microstructure and Optical Properties in Spark Plasma Sintering (SPS)

Hong Y.W., Yeo S.Y., Paik J.H., Cho J-H., Jeong Y.H., Yun J.S., Park W.I., Korea Institute of Ceramic Engineering & Technology, KR

Zinc sulfide (ZnS) is one of the most widely used infrared transmitting window and lens materials for systems operating in the long wave range (8~12 ㎛). ZnS nanoparticles have been intensively studied because of their [...]

Flower-like TiO2 Nanostructures: Synthesis,Characterization and Photocatalytic Properties

Li Y., Liu E., Fan J., Fan X., Hu X., Liu E., Fan J., Fan X., Wu H., Ma Y., Tang C., Northwest University, CN

In this paper three-dimensional (3D) titania nanostructures assembled with rutile nanorods have been fabricated via a hydrothermal reaction route. The effects of preparation parameters including the reaction temperatures and the reactant concentrations, on the microstructure, [...]

Synthesis of nanocrystalline nitrate enclathrated zeolite with intermediate framework structure between sodalite (SOD) and cancrinite (CAN)

Buhl J.-Ch., Cramm S., Leibniz University Hannover, DE

Synthesis of nitrate enclathrated nanocrystalline aluminosilicate zeolite was performed in the system Na2O-SiO2-Al2O3-H20-NaNO3-(TEA) under superalkaline low temperature conditions at 333 K. Formation of nanoparticles occurred already after 3 hours with sizes not exceeding 50 nm [...]

Advancements in the Supercritical Water Hydrothermal Synthesis (scWHS) of Metal Oxide Nanoparticles

Lester E., Blood P., Li J., Poliakoff M., University of Nottingham, UK

Supercritical Water Hydrothermal Synthesis (scWHS) is a relatively simple and environmentally friendly process for the production of potentially valuable metal oxide nanoparticles. This paper presents the conclusions of collaborative work between chemical engineers and chemists [...]

Scale up production of nanoparticles using hydrothermal synthesis

Lester E., Poliakoff M., Li J., Guy B., Tinsley N., Blood P., The University of Nottingham, UK

This paper shows how continuous hydrothermal synthesis can be scaled up for commercial scale production using a patented reactor design. There are severe limitations with most nanomaterial manufacturing methods not excluding hydrothermal synthesis. Hydrothermal synthesis [...]

The Potential use of Fluorescent Nanoparticles from Hydrothermal Synthesis in Cell Imaging

Hobbs H., Briddon S., Lester E., The University of Nottingham, UK

We are using self fluorescing nanoparticles from a nozzle continuous hydrothermal synthesis reactor cell signalling. Most established methods for producing nanoparticles involve relatively noxious chemicals, have a complex and time-consuming sequence of stages, or may [...]
