The work in this thesis has been centred on the light emitting properties of silicon nanocrystals and the possible applications of this particular material platform to various topics ranging from bio-imaging to erbium ion sensitization. Silicon nanocrystals as bio-imaging agent have been investigated by employing coll…
L'objectif principal de cette these est de fournir un nouveau protocole qui permet la detection de la transition de spin (TS) dans un nano-objet unique. Dans ce but, nous proposons d'utiliser la luminescence comme sonde tres sensible qui peut etre employee a des echelles ou d'autres methodes conventionnelles ne sont p…
Development of the intrinsically OH- conductive polymeric electrolyte (alkaline polymer electrolyte, APE) is the critical component to enable the wide application of alkaline fuel cell (AFC) technology. Alkaline polymer electrolyte fuel cell (APEFC) based on AFC technology has been revived recently for applications in…
Trabajo presentado a la conferencia NanoSpain celebrada en Santander (España) del 27 de febrero al 1 de marzo de 2012.
The properties of any semiconductor device rely on the charge separation characteristics at interfaces within that device. The charge separation characteristics include relative energetics, interfacial electronic states, and the presence or absence of insulating layers. More importantly, the interfacial properties det…
The use of chimney necks and offtake pipes, made of polymeric composite materials such as glass reinforced plastic is the comprehensive solution in increasing the life cycle of gas exhaust ducts at their reconstruction and maintenance. The use of envelope made of polymeric composite materials makes it possible to obta…
As biomedical materials and implantable devices int eract with cells and biological fluids, it is fundamental to control the properties of interfaces between the material a nd the biological environment to address the organism resp onse towards a specific direction [1], by precisely desi gning surface chemistries [2],…
Az OTKA K76010 kutatói pályázat keretében nanokontaktusok viselkedését vizsgáltuk, melyekben az áram egyetlen atomon vagy egyetlen molekulán keresztül folyik. A kutatás keretében kifejlesztettünk egy molekulák kontrollált adagolására alkalmas mérőrendszert, mely egyedi molekulák kontaktálását teszi lehetővé folyékony…
The new catalyst is developed for process of oxidation SO2 in SO3 on the basis of a waste of manufactures. Samples of the catalyst of the various form are received. It is investigated efficiency of the catalyst from slimes at various temperature. Perspective ways of a solution of a problem of processing slimes a waste…
By interaction of alpha-oxides with alifatical and aromatical amines a row alkanolamines is received. The solidification of isocyanate containing forpolymers by alkanolamines is carried out and properties of the received polyurethane elastomers are investigated.

The results of investigation of the proportion of structural components in the alloy 25 mas % ZrO 2-75 mas % Al 2O 3 crystallized under nonequilibrium conditions. Found that increasing the cooling rate of the melt proportion between the amount of the primary crystals of corundum and eutectic colonies is not decreasing…
We investigate optical transmission spectra of yttria-stabilized zirconia single crystals that have been implanted with multi-charge Ag ions at the average energy of 168 keV in the dose range of (0.5÷4)·1016 cm-2 and subsequently annealed. The spectra are related to the formation of silver nanoparticles in the single…
Solid electrolyte Bi4V1.7Fe0.3O10.7 was obtained by means of polymer-salt composition pirolysis. There were produced three solid oxide fuel cells containing this electrolyte. Two of them have planar model of fuel cell. The configuration of the third cell is similar to the tube model. The planar cells differ from each…
In our work we have conducted researches intact and cariosity process of enamel and dentin of human tooth using by FTIRspectra-microscopy with use synchrotron radiations. It is shown that enamel caries is characterised by growth of deformation and valence vibrations N-C-O, N-H and C=O that speaks about destructive pro…
We present first-principles theoretical calculations of the structural and electronic properties of bimetallic clusters AunCu38-n. For the former, we first appeal to the lowest energy configurations of AunCu38-n (for different n) that we determined previously from an accurate and reliable optimization algorithm [P. J.…
The adsorption of polyelectrolytes, both as monolayers and as multilayers, was investigated as an easy and non-expensive way of producing lignocellulosic fibrous materials with enhanced mechanical properties. In the first part of the work described in this thesis, the adsorption of a polyelectrolyte monolayer onto the…
Due to the obsolescence of SnPb BGA components, electronics manufacturers that use SnPb solder paste either have to use lead-free BGAs and adjust the reflow process or re-ball these components with SnPb balls. The reliability of Lead-Free and Lead-Containing solder joints for BGA's has been investigated after re-balli…
The article provides a summary of performance of vehicle transmission and brake control for formulating and solving multiobjective parametric problems with adjustable design parameters. Characteristics for regulation of design parameters of transmission and brake control of class “B” passenger car are determined based…
In January 2011, a KTP project between Salford University and Nanoco Technologies was initiated to develop alternative, more efficient commercially viable routes to heavy metal-free quantum dots (QDs) allowing the exploitation of developing markets in the electronics industry. The technology developed by Nanoco was to…
