Ultrasonic Transducer for the Hydrothermal Method

Journal of the Korean Physical Society, 2010
Direct ultrasound irradiation is advantageous to increase the efficiency of the hydrothermal method which can be used for the production of piezoelectric thin films and lead free piezoelectric ceramics. To apply ultrasound directly to the process transducer prototypes were developed regarding the boundary conditions of the hydrothermal method.

TDEM Method for Hydrothermal Water Prospection

70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008
TDEM prospection allowed to reconstruct tectonic setting of a thermal basin, in Viterbo (Central Italy). A productive well was located at the intersection of two faults evidenced by geophysical data, reaching a depth of 127 m. and providing thermal water (58°C) with high productivity (spontaneous discharge 10 L/Sec).

Silver Telluride Nanotubes Prepared by the Hydrothermal Method

Inorganic Chemistry, 2007
Silver telluride nanotubes have been prepared by the hydrothermal process without a template or a surfactant. The as-prepared sample was characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectra, and Raman spectra. The structural phase transition of the sample was observed.

A hydrothermal hot-pressing method: Apparatus and application

Journal of Materials Science Letters, 1986
Loose particles occurring in sediment are transformed into sedimentary rock by a process termed lithification, which is a chemical process that reduces the original porosity by compaction and cementation [1]. A hydrothermal hot-pressing method is intended for artificial lithification.

Defects in ZnO Nanorods Prepared by a Hydrothermal Method

The Journal of Physical Chemistry B, 2006
ZnO nanorod arrays were fabricated using a hydrothermal method. The nanorods were studied by scanning electron microscopy, photoluminescence (PL), time-resolved PL, X-ray photoelectron spectroscopy, and positron annihilation spectroscopy before and after annealing in different environments and at different temperatures.

Synthesis of Na0.5Bi0.5TiO3 powders through hydrothermal method

Journal of Alloys and Compounds, 2010
Abstract Na0.5Bi0.5TiO3 (NBT) powders were successfully prepared by the hydrothermal method using TiCl4 and Bi(NO3)3·5H2O as raw materials and NaOH as mineralizer. The phase composition and particle morphology of the as-prepared powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron ...

CuS nanostructures prepared by a hydrothermal method

Journal of Alloys and Compounds, 2011
Abstract Without using any surfactant or template, novel CuS three-dimensional (3D) structures consisting of nanosheets were successfully synthesized via a convenient one-step hydrothermal approach. X-ray diffraction pattern showed that the as-prepared product was pure hexagonal phase CuS. Scanning electron microscopy and high-resolution transmission

Cerium doped NiO nanoparticles by hydrothermal method

AIP Conference Proceedings, 2020
Pure and cerium doped nickel oxide nanoparticles were prepared by hydrothermal method. Structural, optical, and morphological properties were studied by employing XRD, Raman, PL, and SEM analyses. The information about the functional group and chemical structure of the prepared sample was analyzed through FTIR.
