In this work, the effect of the incorporation of hydroxyapatite and comonomer containing amine groups on the mechanical, thermical, morphological and chemical properties of acrylic bone cements was studied. Cements was prepared with 2-diethyl amino ethyl acrylate (DEAEA) as comonomer in the liquid phase. It was found…
The nano-scale interaction between polymer molecules and nanoparticle is a key factor in determining the macro-scale strength of the composite. In recent years numerous efforts have been directed towards modeling nanocomposites in order to better understand the reasons behind the enhancement of mechanical properties,…
After a first part devoted to the oxidation kinetic at high temperature for HfC-containing nickel-based alloys this second part deals with the phenomena which can be post-mortem observed by metallography on the oxidizedNi-25Cr-0.25 to 0.50C-3.72-5.58Hf alloys. The samples generated in the first part were effectivelyme…
Rising energy prices and greater environmental awareness along with stringent emissions legislation in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied in this work, is heat recovery in the exhaust gas reci…
Bismuth ferrite (BFO) is a multiferroic material with cross-correlation between magnetic and electric orders. With no applied external fields the spin structure of BFO is anitferromagnetic and cycloidal. This ordering prevents the detection of the weak ferromagnetism known to exist in the material. The application of…

In this article, recent progress of polyion complex vesicles, PICsomes, were reviewed, particularly focusing ontheir design strategy, preparation and material–loading methods, characteristic properties, and biomedical applica-tions.
The numerical analysis of the diffraction of Gaussian beam and mode Gauss Laguerre (0,1) was held on a cylinder with a sub-wavelength radius with circular polarization of the input light, based on finite-difference time-domain method. The characteristics that provide subwavelength focusing such as the size of details,…
Partitioning and transmutation (P&T) is a promising method to safely handle minor actinides which origin from energy production by nuclear fission. In this concept, actinide co-conversion processes play an important role to close the fuel cycle. During the heterogeneous recycling of minor actinides, oxidic materials c…
The main objective of this work was to obtain fundamental insights in the aqueous vanadium precursor chemistry and in their relation to the vanadium oxide stoichiometry=phase formation, obtained via a solution deposition route.
A non–equilibrium molecular dynamics (MD)technique can be effectively utilized for calculation of permeability ofgases in microporous inorganic membranes as well as adsorption and diffusion simulations combined with the “sorp-tion–diffusion (SD)model”. The effects of microporous structures, such as membrane density an…
Improving resource efficiency and effectiveness of materials is becoming very important in itself in the current economy. Though some of the manufacturing of structured components has been undertaken with polymeric materials, there has been little use of sheet polymeric materials in order to develop micro-channel devi…
\nThis thesis summarizes the knowledge of the possibility of using organic fibres as dispersed reinforcement into cement composites. It is concretely a summary of knowledge about the types and properties of synthetic and cellulosic fibres, their influence on the properties of fresh and hardened cement composite and la…
En esta Tesis Doctoral se lleva a cabo la caracterización del estado fundamental y primer estado excitado triplete de una serie de hidrocarburos policíclicos aromáticos (PAHs) con carácter pro-aromático o quinoide basados en la unidad para-quinodimetano (p-QDM). Se estudian cuatro familias de compuestos divididas en:…
Ideal cancer therapy without side effects would be achieved by drug carriers, which can deliver anticancer drugsspecifically to cancer cells in tumor tissue. Thus, it is necessary to control both the biodistribution and cellularuptake of drug carriers. For this, physicochemical properties, especially surface charge of…

Zaradi zahteve po varovanju naravnih virov so zahteve po uporabi recikliranih materialov vse bolj pogoste tudi v gradbeni praksi, se posebej, ker je gradbenistvo velik porabnik naravnih virov. Uporaba recikliranih agregatov za cementne betone pomeni manjso porabo naravnih agregatov. Po drugi strani pa morajo cementni…
