Abstract:

Evaporation cells based on a new heating principle will be designed, fabricated and tested. This heating principle is based on direct resistive heating of two concentric tubes made on a refractory metal (Ta, Mo, W), with thin walls (0.1-0.2 mm), subject to a high electrical current (60-100 A). The inner pipe contains the material to be evaporated. The outer pipe, which also warms up, acts at the same time as a thermal screen for the inner pipe: as a consequence, higher temperatures are achieved in the inner part and also a higher amount of power is dissipated inside the inner pipe. The warming up to very high temperatures (over 2000 C) proceeds in a few tens of seconds, to be compared with several tens of minutes in standard evaporation cells where a crucible is warmed by using a W filament. Also, a precise temperature calibration may be obtained as function of the heating current only, whereas in conventional cells thermocouples are used. These thermocouples require additional vacuum current feedthroughs and also their thermal contact to the crucible may be problematic. A third advantage of the new principle is its relative low cost, based on the fact that the only expensive parts are the refractory material pipes. A new concept (dismountable assembly) will be developed also for the water cooling of the cell, whereas a single high current vacuum feedthrough is sufficient. One anticipates easy and fast manufacture of such devices, resulting in low delivery terms, as compared with 3-6 months for the actual evaporators. The estimated market is of some 500-1000 units in the European Community, whereas the stipulated benefit is of 5000 Euro per unit. The project will (i) implement the new heating principle; (ii) implement the new water cooling principle; (iii) achieve accuracte temperature calibration; (iv) demonstrate the ability to evaporate at high temperature, especially of metals that are usually evaporated by electron bombardment: Ti, Cr, V, Zr, Nb.

Abstract:

This project is dedicated to adapt and improve the magnetic measurements techniques for nanoparticle systems dispersed or not in liquid media having superparamagneic and bimagnetic (hard/soft) core-shell structures. The project focuses only on the magnetometry techniques. The synthesis of new superparamagnetic and bimagnetic nanocomposites is done trough other research projects of the author research group. The foreseen results are to reveal the limitation of individual approaches by investigating a phenomenon by different techniques. The Brownian relaxation contribution to the magnetization behavior will be obtained by a comparative study of the energy barrier distributions of dispersed nanoparticles in both liquid and frozen dilution medium. The applicative potential in hyperthermia of superparamagnetic and bimagnetic core-shell nanoparticle systems will be investigated by AC minor hysteresis. The effect of the dilution on the magnetic behavior will be studied by AC susceptibility measurements. FORC and Henkel techniques will give additional information on interparticle interaction, than the common AC and DC temperature dependence of magnetization.

Abstract:

This project intends to provide a financial background for developing the community of Surface Science in Romania. Thematics from physics and chemistry of surfaces will be tackled together with applications of surface science in biology and in technology; also new standards will be proposed for consistent data interpretation. The Project clusterizes the most important Romanian teams with preoccupations in surface science, namely all X-ray photoelectron spectroscopy teams with most of the community of thin film deposition, cluster and nanoparticle physics, surface reactivity, surface chemistry and photochemistry, multilayer physics and applications, magnetic fluids, functionalization of surfaces, cell attachment, studies of cellular membrane. The research teams belong to highly prominent Universities and Research Institutes from practically all geographical areas of the country. The Consortium disposes of infrastructure exceeding 10 million euros, of more than one hundreed highly qualified scientists which have generated during the past years more than 3 % of the national scientific visibility. The research will concentrate into four main areas: (i) magnetic properties of surfaces and low-dimensional systems; (ii) electrical properties of surfaces and heterostructures; (iii) surface chemistry; (iv) application of surface science in functionalized systems and in biology, together with (v) an area concentrating on standardization in X-ray photoelectron spectroscopy, Auger electron spectroscopy and related techniques. Each area is divided into several thematics; each thematic has at least one in-charge scientist. This Project will foster the surface science community in Romania and will contribute strongly to the development of high-technological industrial preoccupation in all geographical areas concerned. Several cutting-edge applications are also foreseen by pursuing the fundamental research proposed.
