Autor: F. Jiménez, María Asunción Illarramendi, I. Ayesta, S. Diamant, Joseba Zubia, O. Palchik, Itxaso Parola, Jon Arrue

Publikováno v: SPIE Proceedings.

The emission properties of rhodamine-6G doped step-index cladded and uncladded thermoset fibres have been studied for a transversal excitation configuration. Measurements include a deep analysis of the amplified spontaneous emission and a detailed st

Autor: M. Deutsch, Aharon Gedanken, C. N. Sukenik, O. Palchik, B. M. Ocko, O. Gershevitz, R. Turgeman

Publikováno v: Crystal Growth & Design. 4:169-175

Highly ordered ZnO crystals of 0.15 μm width and 0.5 μm length were grown on silicon wafers coated with a monolayer of SiCl3(CH2)11−O−C6H5 molecules. Various techniques (contact angle measurements, ellipsometry, ATR-FTIR) were employed for dete

Synthesis of Europium Oxide Nanorods by Ultrasound Irradiation

Autor: Vilas G. Pol, Aharon Gedanken, O. Palchik, Israel Felner

Publikováno v: The Journal of Physical Chemistry B. 106:9737-9743

Europium oxide nanorods have been prepared by the sonication of an aqueous solution of europium nitrate in the presence of ammonia. The properties of the Eu2O3 nanorods were characterized by X-ray diffraction, thermogravimetric analysis, differential

Sonochemical Synthesis of Mesoporous Tin Oxide

Autor: and A. Zaban, Aharon Gedanken, Shlomit Chappel, Divesh N. Srivastava, O. Palchik

Publikováno v: Langmuir. 18:4160-4164

Nanosize mesoporous tin oxide was prepared by a sonochemical approach, using tin ethoxide as the inorganic precursor and cetyltrimethylammonium bromide as the organic structure-directing agent. The formation of mesoporous SnO2 was confirmed by compar

Sonochemical Deposition of Silver Nanoparticles on Silica Spheres

Autor: Divesh N. Srivastava, Vilas G. Pol, and A. M. Weiss, O. Palchik, V. Palchik, M. A. Slifkin, Aharon Gedanken

Publikováno v: Langmuir. 18:3352-3357

Silver nanoparticles with an average size of ∼5 nm were deposited on the surface of preformed silica submicrospheres with the aid of power ultrasound. Ultrasound irradiation of a slurry of silica submicrospheres, silver nitrate, and ammonia in an a

Synthesis of morphologically controlled lanthanum carbonate particles using ultrasound irradiation

Autor: Aharon Gedanken, Pethaiyan Jeevanandam, O. Palchik, Yu. Koltypin

Publikováno v: Journal of Materials Chemistry. 11:869-873

Lanthanum carbonate particles, which can be used as precursors to lanthanum oxide, have been synthesised from lanthanum nitrate and urea in the presence and absence of ultrasound irradiation. The use of ultrasound irradiation was found to have a rema

Microwave-assisted polyol method for the preparation of CdSe 'nanoballs'

Autor: O. Palchik, Aharon Gedanken, V. Palchik, M. A. Slifkin, R. Kerner, Aryeh Weiss

Publikováno v: Journal of Materials Chemistry. 11:874-878

The microwave-assisted polyol reduction method was applied to the preparation of CdSe “nanoballs”. The cubic and hexagonal forms of the CdSe nanoparticles obtained were analyzed by XRD, TEM, HRTEM, UV-VIS, photoluminescence (PL) and photoacoustic
